博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主小傅哥。 + +不少小伙伴都想放在简历上放一个动态博客链接，展示自己的过往技术经历和可运行的项目展示。通过这样的方式提高自己在面试中的竞争力。但因为没做过，又不知道从哪开始，找的一些案例教程又都很复杂。所以，小傅哥来帮你一下，让你SoEasy的搞定这东西。 + +
+ +
+ +当这个男人👨🏻准备下手的时候，一切技术将变得简单、容易，好理解！ + +我把本次的分内容定义为简历博客，并已经做好了博客的框架（[vuepress](https://theme-hope.vuejs.press/zh/)）和内容案例，以及部署需要的Nginx配置。如果你需要部署到线上，那么需要准备一台云服务器（[2c2g 50元/1年](https://gaga.plus/yun.html)）。另外你还可以注册一个域名（ICP备案2周），这样就可以通过域名访问你的专属博客了。【要我说，每个程序员👨🏻‍💻都应该有一个自己的域名，有了它你才有了做一些事情的可能】。**接下来我会带着你搭建一个如图所示的个人简历博客** + +
+ +
+ +那么，接下来小傅哥就带着你，完成下简历博客的搭建。 + +>文末提供了8个Java实战项目，嘎嘎提升简历竞争力。💐 + +## 一、搭建准备 + +- 简历博客项目：[https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-blog](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-blog) +- 一台云服务器，2c2g 推荐 50元/1年 [https://gaga.plus/yun.html](https://gaga.plus/yun.html) +- 云服务器搭建 Docker、安装 Portainer 教程地址（包括学习视频）：[https://bugstack.cn/md/road-map/docker.html](https://bugstack.cn/md/road-map/docker.html) +- 域名和域名备案（ICP备案2周），未购买也可以完成本节课程的操作。 +- SSL 申请，如果有域名了，可以申请免费的 SSL 让域名地址支持 HTTPS。申请地址：[https://yundun.console.aliyun.com/?p=cas#/certExtend/free/cn-hangzhou](https://yundun.console.aliyun.com/?p=cas#/certExtend/free/cn-hangzhou) +- Node.js 安装，地址：[https://nodejs.org/en/download](https://nodejs.org/en/download) - `选择自己机器适配的版本安装即可` + +## 二、项目说明 + +这里小傅哥已经把博客框架、内容案例、部署博客的环境，都准备好了。你只需要下载到本地就可以使用。 + +
+ +
+ +本博客采用 [VuePress Theme Hope](https://theme-hope.vuejs.press/zh/) 模板进行搭建。当你能完成部署本博客后，还可以参考模板做一些其他的扩展以及各类喜欢插件的安装。 + +- src 目录下，为博客的框架模板和已经写好的案例。在 `package.json`中有一个 `docs:build` 用于构建，还有一个 `docs:dev`用于本地启动测试。 +- dev-ops 提供的是博客的部署，这里的 docker-compose.yml 是 Docker 执行脚本安装 Nginx 环境。 +- 小傅哥在 `src/.vuepress-> config.ts`文件中下配置了把项目 build 到 nginx/html 文件夹。这样可以更加方便我们部署。 + +## 三、部署项目 + +当你把 xfg-dev-tech-blog 项目检出到本地，使用 IntelliJ IDEA 或者 WebStrom 工具打开后。会提示你执行 npm install 安装环境。如果没有提示你也可以自己在项目 Terminal 下执行。执行完安装就可以做博客的部署了。 + +
+ +
+ +### 1. 构建项目 + +
+ +
+ +- 打开项目的 `package.json`里面有`构建`和`运行`命名。 +- 构建的操作会把工程打包为 HTML 文件写入到 dev-ops/nginx/html 文件夹下。 +- 运行的操作会直接本地启动服务，启动后你可以在本地预览。这样你在修改一些内容的时候也可以随时看到效果。 + +### 2. 构建结果 + +
+ +
+ +- 如步骤操作，完成构建。当你看到 `dev-ops/nginx/html` 下有对应的一堆文件了，说明构建成功了。 + +### 3. Nginx 配置 + +对于 Nginx 的配置提供了3种方式，分别包括；IP访问、HTTP域名访问、HTTPS域名访问。 + +
+ +
+ +#### 1. localhost.conf + +这个配置方式为了方便，没有域名的伙伴们测试使用。也就是你部署后可以直接通过IP进行访问。 + +```shell +server { + listen 80; + listen [::]:80; + + location / { + root /usr/share/nginx/html; + index index.html; + } + + error_page 500 502 503 504 /50x.html; + location = /50x.html { + root /usr/share/nginx/html; + } + +} +``` + +- 直接把 80 请求转发到本地的根目录地址的 html 文件上即可 + +#### 2. http.blog.conf + +##### 2.1 配置域名解析 + +
+ +
+ +- 如果你有云服务器和域名，那么可以先如图，配置下域名解析地址。 + +##### 2.2 nginx 脚本 + +```shell +server { + listen 80; + listen [::]:80; + server_name blog.gaga.plus; + + location / { + root /usr/share/nginx/html; + index index.html; + } + + error_page 500 502 503 504 /50x.html; + location = /50x.html { + root /usr/share/nginx/html; + } + +} +``` + +#### 3. https.blog.conf + +如果你有域名那么还可以配置免费的ssl验证，配置完成后把 ssl key、pem 文件放到 dev-ops/nginx/ssl 文件夹下并上传到云服务器上。详细介绍：[https://bugstack.cn/md/devops/2023-04-18-nginx.html#_4-1-%E5%88%9B%E5%BB%BA%E8%AF%81%E4%B9%A6](https://bugstack.cn/md/devops/2023-04-18-nginx.html#_4-1-%E5%88%9B%E5%BB%BA%E8%AF%81%E4%B9%A6) + +```shell +server { + listen 80; + listen [::]:80; + server_name blogs.gaga.plus; + + rewrite ^(.*) https://$server_name$1 permanent; +} + +server { + listen 443 ssl; + server_name api.gaga.plus; + + ssl_certificate /etc/nginx/ssl/blogs.gaga.plus.pem; + ssl_certificate_key /etc/nginx/ssl/blogs.gaga.plus.key; + + ssl_session_cache shared:SSL:1m; + ssl_session_timeout 5m; + + ssl_ciphers HIGH:!aNULL:!MD5; + ssl_prefer_server_ciphers on; + + location / { + root /usr/share/nginx/html; + index index.html; + } + + error_page 500 502 503 504 /50x.html; + location = /50x.html { + root /usr/share/nginx/html; + } +} +``` + +- 这个方式就是配置 ssl 的方式。 + +### 4. 上传文件 + +
+ +
+ +- 小傅哥这里使用的是 [https://termius.com/](https://termius.com/) 连接云服务器的 SSH 工具，自带 SFTP 。`你也可以使用其他 SSH/FTP 工具` +- 通过这个工具，连接云服务器，并把我们在工程下创建的 `dev-ops` 上传到云服务器端。 + +### 5. 服务启动 + +接下来，你只需要在云服务器进入到 dev-ops 文件夹下，执行脚本 `docker-compose -f docker-compose.yml up -d` 即可完成部署。 + +
+ +
+ +
+ +
+ +- 在你初次部署的时候，会拉取 Nginx 镜像。拉取完成后则会自动部署。 +- 部署完成后可以进入到 portainer 中查看 nginx 运行，以及进入到日志中查看运行情况。 + +### 6. 访问博客 + +- IP地址：[http://117.72.37.243/](http://117.72.37.243/) +- HTTP地址：[http://blog.gaga.plus/](http://blog.gaga.plus/) +- HTTPS地址：[https://blogs.gaga.plus/](https://blogs.gaga.plus/) + +
+ +
+ +
+ +
+ +**全部完成撒花 💐** 现在你就可以在简历上挂一个自己的博客了，还可以在博客中秀出自己的技术肌肉💪🏻，赢得面试官的青睐！ + +>当然，有了简历博客，最好配有一套对应的高质量实战项目，撑起简历的技术度。那些CRUD/XXX管理系统，现在是越来越没竞争力了。早点学一些，每天积累一点，就能让自己有更多的选择。 + +## 四、实战项目 + +小傅哥工作10年+，深刻感受到在不同阶段(毕业~3年，3年~5年、5年+)都要有对应的能力，才能踏上换乘的列车。为了让自己的职业生涯走的更加稳妥，就不要只把自己当成满足工作需要的工具。早些积累、早些积累自己的技术栈体系闭环。这是非常重要的！！！ + +>小傅哥把工作中的技术经验，陆续的编写出对应的博客和实战项目，整整写了3年多。这些内容可以让一个研发小白成长为技术大牛！ + +

+所以为了能让更多的程序员👨‍💻‍更好的接受设计思想和架构思维，并能运用到实际的业务场景。本书的作者`小傅哥`，投入50天时间，从互联网实际业务开发中抽离出，交易、营销、秒杀、中间件、源码等22个真实场景，来学习设计模式实践使用的应用可上手技能。 + +### 1. 谁发明了设计模式？ + +设计模式的概念最早是由 `克里斯托佛·亚历山大` 在其著作 `《建筑模式语言》` 中首次提出的。 本书介绍了城市设计的 “语言”，提供了253个描述城镇、邻里、住宅、花园、房间及西部构造的模式， 而此类 “语言” 的基本单元就是模式。后来，`埃里希·伽玛`、 `约翰·弗利赛德斯`、 `拉尔夫·约翰逊` 和 `理查德·赫尔姆` 这四位作者接受了模式的概念。 1994 年， 他们出版了 `《设计模式： 可复用面向对象软件的基础》` 一书， 将设计模式的概念应用到程序开发领域中。 + +其实有一部分人并没有仔细阅读过设计模式的相关书籍和资料，但依旧可以编写出优秀的代码。这主要是由于在经过众多项目的锤炼和对程序设计的不断追求，从而在多年编程历程上提炼出来的心得体会。而这份经验最终会与设计模式提到的内容几乎一致，同样会要求高内聚、低耦合、可扩展、可复用。你可能也遇到类似的经历，在学习一些框架的源码时，发现它里的某些设计和你在做开发时一样。 + +### 2. 我怎么学不会设计模式？ + +钱也花了，书也买了。代码还是一坨一坨的！设计模式是由多年的经验提炼出来开发指导思想。就像我告诉你自行车怎么骑、汽车怎么开，但只要你没跑过几千公里，你能记住的只是理论，想上道依旧很慌！ + +**所以**，本设计模式专题系列开始，会带着你使用设计模式的思想去优化代码。从而学习设计模式的心得并融入给自己。当然这里还需要多加练习，一定是*人车合一*，才能站在设计模式的基础上构建出更加合理的代码。 + +### 3. 适合人群 + +1. 具备一定编程基础在工作1-3年的研发人员 +2. 希望通过此书提升编码思维，剔除到代码中的坏味道 +3. 有意愿成为架构师，但还处在一定瓶颈期 +4. 学习过设计模式，可是一直想找到一本可以落地真实场景参照的书籍 + +### 4. 我能学到什么 + +1. 优化平时开发中的ifelse语句，让代码更加整洁 +2. 看设计模式不再是用理论生搬硬套，这次可以有点用 +3. 站在更高的角度去看待编程开发，学会更多的面向对象的思维，尤其是；接口、抽象类、多态等使用 +4. 升职、加薪，良好的代码是效能提升的基础，成为本组编码最靓的精神小伙 + +### 5. 阅读建议 + +本书属于实战型而不是理论介绍类书籍，每一章节都有对应的完整代码，学习的过程需要参考书中的章节与代码一起学习，同时在学习的过程中需要了解并运行代码。学习完成后进行知识点的总结，以及思考🤔这样的设计模式在自己的业务场景中需要如何使用。 + +## 三、书中目录 + +设计模式遵循六大原则；单一职责(`一个类和方法只做一件事`)、里氏替换(`多态，子类可扩展父类`)、依赖倒置(`细节依赖抽象，下层依赖上层`)、接口隔离(`建立单一接口`)、迪米特原则(`最少知道，降低耦合`)、开闭原则(`抽象架构，扩展实现`)，会在具体的设计模式章节中，进行体现。 + +### 1. 创建型模式 + +**这类模式提供创建对象的机制， 能够提升已有代码的灵活性和可复用性。**

+ +
+ +**小傅哥的 WaLiCode，AI IDE Coding v0.1.0 发布！** + +市面上优秀的 AI IDE 非常多，但论最好用的还得是 Claude Code。所以借助于这些的“源码”学习，小傅哥基于 Tauri（Rust）桥接 Claude +Code 能力（这个设计也可以桥接其他的，如 OpenCode），在上层做一套 AI IDE 应用服务实现。通过工程、工程、代码块（含图片）对话的方式，驱动代码开发辅助提效处理。 +`也让大家可以通过 WaLiCode 感受到 Claude Code 的巴士体验！` + +

+ +
+ +- 多厂家模型灵活配置，支持自定义 OpenAI 格式的各类大模型接口，无论是智谱、火山引擎还是本地部署的模型，均可一键接入，满足不同场景的开发需求。 +- 各类的 token/coding plan，支持 OpenAI 格式就可以配置使用。 + +### 2. 产品首页 + +
+ +
+ +- 首先，安装软件后，打开 WaliCode 在初次使用会引导你配置 apikey，可以添加你需要的模型。得益于 Claude Code 和 WaliCode + 的扩展，上下文的使用会非常准确和节省，也就让你的模型消耗也会很低。 +- 之后，你可以打开文件夹选择自己的工程，进行对话框对话，以及智能终端对话。在对话中，你可以把模块、文件、代码以及图片，都放到对话框中，之后进行诉求描述。 + +### 3. 添加技能（Skills） + +
+ +
+ +- 在设置中可以添加你需要扩展的 Skills 技能，支持zip包上传、git地址直接拉取，可以非常方便的扩展 Skills。 +- 同时还为你提供了 SkillMP、ClawHub 官网 Skills 地址，随时去找你需要的技能扩展到工程里。 + +### 4. 添加服务（MCP） + +
+ +
+ +- 在设置中可以添加 MCP 服务能力，支持 stdio、sse、json 多种配置方式。极大的方便用户扩展自己的功能使用场景。 + +### 5. 智能终端 + +
+ +
+ +- 这是一个附属功能，方便用户可以在终端直接使用 Claude Code 能力。属于原生的扩展支持。 + +### 6. Git 能力 + +
+ +
+ +- 内置 Git 操作面板，支持分支切换、代码提交与状态查看。结合 AI 能力，还能自动分析变更并生成规范的提交信息。 + +> 好嘞，欢迎下载体验 [https://walicode.xiaofuge.cn/](https://walicode.xiaofuge.cn/) 遇到问题可以群里交流 😄 + +## 三、扩展学习（AI Agent） + +如果你希望自己不只是一个业务开发工程师，也具备 AI Agent 开发能力，让自己在这个 AI +时代做点什么，那么下面的教程你可以学习下。小傅哥也是在这些项目中积累的经验，可以一次次在 AI 快速迭代中，做一些有意思的事情。 + +

+ +
+ +- 2025年11月27日，Google 正式在 Maven 仓库管理中心，推送了 0.4.0 版本 ADK，该版本新增加了 Spring AI 的集成。[google-adk-spring-ai](https://central.sonatype.com/artifact/com.google.adk/google-adk-spring-ai) 至此，也因此，小傅哥决定基于这套服务组合，设计智能体脚手架。 +- 首先，Google ADK 是一个智能体框架，他自身也是支持直接对接各类大模型的 API，以及构建 ChatModel 的。但在整合 Spring AI、LangeChain4J 以后，Google ADK 的使用，将会得到已经使用上述组件的公司更大的青睐。 +- 之后，Spring AI 解决的 AI 对接的前半部分，让你可以把 AI API、Model、Prompt、RAG、Tool（Function、MCP）等，非常方便的构建出一个单一的 AI Agent 服务（也可以称之为是一个客户端）。 +- 然后，Google ADK 解决的是，多个 AI Agent 怎么协同工作的问题。这里包括，Sequential 序列顺序执行、Loop 循环执行、Parallel 并行执行，而这些执行方式，又可以组合搭配的配置到一个 Sequential 中进行顺序执行（注意图中颜色）。绿色的是大模型服务，绿色部分可以被深黄色或者浅青色包装，之后在组合到 SequentialAgent - 序列执行中。 +- 最后，Google ADK 提供了记忆上下文 Runner 执行器（也可以自己扩展实现），在这里又提供了钩子插件，你可以对执行过程中的流程，进行拦截。这个过程类似 Spring 容器中对 Bean 对象的处理，before、after 的过程。 + +### 2. 系统的分层结构 + +如图，整体简要架构设计（剥离其他流程，方便理解）； + +
+ +
+ +整个应用架构分为3层，包括；基础底座、脚手架、业务场景； + +- 基础底座，负责整 Spring AI + Google ADK 框架的使用，这里的重点在于整个智能体工作流程的设计和使用（第2部分20节课程）。 +- 脚手架，将基础底座使用 maven 抽取出脚手架，脚手架可以让我们快速复刻出一套基础工程（第3部分3节）。 +- 业务场景，结合 draw.io 绘图操作 + ai agent 智能体，做一套AI交互式画图系统（第4部分6节）。 + +### 3. 底座的运行流程 + +
+ +
+ +- 首先，从用户基于脚手架创建完成后，在使用 YML 文件进行智能体的配置，之后在启动项目后，会进行一些利的装配。api、model、agent、workflow、runner，再到 spring 容器。 +- 其中，关于智能体的工作流组装是非常巧妙的，可以自由组合出多种类型智能体。这部分不需要硬编码即可完成。 +- 最后，是整个内容装配完成后，提供了通用的接口能力可以进行对话。 + +### 4. 脚手架配置发布 + +
+ +
+ +- 左侧，对现有工程使用 maven-archetype-plugin 插件，构建工程脚手架。将当前的工程打包成一个可复用的 Archetype 模板。 +- 中间，打包好的脚手架，可以在本地直接使用，也可以发布jar到私服，让大家都可以使用。私服部分，后续在做处理。 +- 右侧，使用方可以基于命令，或者 IntelliJ IDEA 配置 Maven 脚手架的方式，创建和启动工程。这一节，我们先通过命令的方式使用。 + +## 四、应用场景举例 + +### 1. 普通对话 + +
+ +
+ +- 智能体搭建后，可以进行对话操作，基于你配置的 MCP 能力，它可以做很多事项。 + +### 2. draw.io + 画图 + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +## 一、项目介绍 + +面试官您好，本套 AI Agent 综合智能体脚手架 项目，主要为降低智能体开发门槛、提升业务系统集成效率而构建。项目涵盖了：`工程脚手架自动生成`、`智能工作流编排`、`多模态交互（文本/绘图/动作）` ，以及`手机自动化网关控制`等核心功能和场景方案。 + +整套项目，核心抽象并拆分了 AI Agent 执行过程所需的各项组件（`Armory 装配域` 、`Runner 执行器` 、 `Skills 技能库`等）到结构化的配置定义中，使其具备自由配置、灵活编排的特性。以此方式，开发者可以结合实际业务场景诉求，像搭积木一样编排复杂的智能体协作流程——例如项目中实现的 "AI + Draw.io 交互式绘图" 和 "Android 手机自动化网关 - MobileOpenClaw" 场景，达到“业务需要什么能力，就组装什么节点”的 AI Auto Agent 效果。 + +该项目在架构设计上，严格遵循 DDD（领域驱动设计） 分层架构进行开发，核心采用了 **组合模式（Composite Pattern）**，构建智能体的执行规则树（支持串行、并行、循环流转），并结合**工厂模式 （创建不同类型的 Agent/Tool 节点）**、 **策略模式 （处理不同的模型调用策略）** 以及 **责任链设计思维模式（这块按照不同的理解，说成规则树也可以） （处理节点间的上下文传递）** 来处理具体流程细节。这种设计不仅解耦了底层模型（支持 Spring AI、Google ADK）与上层业务逻辑，也使得系统在面对未来各类扩展性诉求（如新增 MCP 协议、对接新模型）时，能够更加灵活方便地进行迭代。 + +## 二、简历模板 + +**项目名称**：AI Agent 智能体通用脚手架（可以自己起项目名称） + +**项目架构**：DDD 领域驱动设计（六边形架构）、事件驱动架构、前后端分离、组合模式规则引擎、模块化微服务 + +**核心技术** ：Spring Boot 3.4、JDK 17+、Spring AI（LangChain4j）、Google ADK（Application Development Kit）、Kotlin (Android)、MCP (Model Context Protocol)、RAG (Vector Store)、Netty、Websocket、React、Draw.io (mxGraph)、TypeScript、Maven Archetype、Docker、Nginx - `不用都写，可以适当减少。` + +**项目描述** ： + +本项目是一套企业级 AI Agent 综合解决方案与标准化脚手架，旨在解决智能体开发中“编排难、落地难、复用难”的痛点。系统基于 DDD 分层架构，创新性地设计了 Armory（装配域） 引擎，将复杂的业务流程抽象为可配置的节点（Node）流转。支持用户通过低代码方式，动态组装 Advisor（顾问） 、 Tools（工具） 和 Workflows（工作流） 。此外基于本套脚手架，实现了从“文本对话”到“自动绘图（Draw.io）”再到“物理设备控制（手机网关）”的全链路智能化。该平台不仅显著降低了 AI 应用的开发门槛，还通过标准化的 MCP 协议，实现了跨生态的能力互通。 + +**核心职责** ： + +- 智能体架构设计与 DDD 建模 ： + + - 主导系统的领域驱动设计，划分 Armory（装配） 、 Runner（执行） 、 Skill（技能）等核心领域。采用 六边形架构 解耦底层模型依赖（Spring AI / Google ADK），确保系统可无缝切换不同的大模型供应商（OpenAI, Claude, DeepSeek）。 + - 设计基于 组合模式（Composite Pattern） 的执行规则引擎，实现了 Loop（循环优化） 、 Parallel（并行处理） 、 Sequential（串行执行） 等多种编排策略，支持复杂的动态工作流配置。 +- 核心组件抽象与开发 ： + + - 拆解并标准化 AI Agent 的核心原子能力，构建了包括 AgentNode （智能体节点）、 AiApiNode （接口节点）、 RouterNode （路由节点）在内的组件库。 + - 设计 DynamicContext（动态上下文） 机制，利用 责任链模式 在节点间传递会话状态与中间结果，解决了多智能体协作时的数据共享与状态一致性问题。 +- 多智能体协作与可视化场景实现（AI + Draw.io）- `这个场景可以独立展开作为一个简历` ： + + - 针对业务流程图绘制场景，设计了 Analyst（需求分析） -> Drawer（绘图执行） -> Reviewer（质量审查） 的多智能体协作链路（Multi-Agent System）。 + - 基于 React + Draw.io (mxGraph) 定制前端组件，开发了专门的 JSON 交互协议，使 AI 能够直接生成和修改 XML 图表数据，实现了“一句话生成专业 UML/流程图”的端到端能力。 + - 集成并适配（百度搜索） https://sai.baidu.com 等公开 MCP Server 资源，让绘图可以检索网络资源。 +- 智能体与硬件设备交互（端侧网关建设） - `这个场景可以独立展开作为一个简历` ： + + - 开发了 MobileOpenClaw（手机网关） ，通过 Netty 长连接 与 Android 端 AccessibilityService（无障碍服务） 通信，赋予 AI 操作物理设备的能力（点击、滑动、截图）。以 AutoPhone GLM 为参考，做设备通信设计。 + - 使用 auto-glm-9b 模型，分析用户诉求，网关网关入口下达操作指令。让手机端完成用户的行为动作。如；点赞、下单、刷抖音、收藏、发微信，等行为动作。 +- 脚手架工程化与提效 ： + + - 设计并发布 Maven Archetype 脚手架，支持一键生成包含完整依赖与最佳实践的 AI 工程代码。 + - 实现了 Agent 预热机制 ，在 Spring 容器启动时动态加载和校验模型配置，支持运营人员在不重启服务的情况下，通过配置中心热更新 Prompt 和编排逻辑。 + +## 三、面试题归档 + +### 项目架构与设计模式 + +#### 1. 请简述本项目的整体架构设计，以及为什么选择 DDD（领域驱动设计）？ +**参考答案：** +本项目采用了 **DDD（领域驱动设计）** 配合 **六边形架构（Hexagonal Architecture）**。 +- **分层设计**：将系统划分为 **API 接口层**（Controller/Trigger）、**应用层**（Service/Application）、**领域层**（Domain/Model）和 **基础设施层**（Infrastructure）。 +- **核心优势**： + - **解耦业务与技术**：核心业务逻辑（如 Agent 编排、策略执行）定义在 Domain 层，不依赖具体的 AI 模型（OpenAI/Claude）或数据库实现。通过 **适配器模式（Adapter Pattern）** 在 Infrastructure 层实现具体技术细节，方便随时替换底层 AI 服务商。 + - **高内聚低耦合**：各层职责清晰，便于单元测试和维护。例如，Armory 装配域专注于智能体构建，Chat 领域专注于对话逻辑。 + +#### 2. 在“智能体装配（Armory）”模块中，你是如何处理复杂的配置解析和对象构建的？使用了哪些设计模式？ +**参考答案：** +- **设计模式**：核心使用了 **组合模式（Composite Pattern）** 和 **责任链模式（Chain of Responsibility）** 的思想，构建了一个 **节点（Node）处理管道**。 +- **实现逻辑**： + - 将复杂的 Agent 构建流程拆解为一系列独立的 **Node**（如 `AiApiNode` 配置 API、`ChatModelNode` 配置模型、`AgentNode` 实例化智能体、`AgentWorkflowNode` 处理编排）。 + - 定义了统一的 `IArmoryService` 接口和 `AbstractArmorySupport` 抽象类，确保所有节点遵循相同的规范。 + - 使用 **工厂模式（Factory Pattern）**（`DefaultArmoryFactory`）来创建和管理这些节点。 + - 通过 **上下文对象（DynamicContext）** 在节点间传递配置数据，避免了方法参数爆炸，实现了构建逻辑的 **高扩展性**（新增节点只需实现接口并注册即可）。 + +#### 3. 项目中是如何实现 MCP (Model Context Protocol) 的？特别是“本地 MCP”是如何设计的？ +**参考答案：** +- **多协议支持**：项目支持 **SSE**（Server-Sent Events）和 **Stdio** 标准协议，通过 `McpClient` 统一封装。 +- **本地 MCP 设计**： + - **策略模式（Strategy Pattern）**：定义了 `ToolMcpCreateService` 策略接口，分别实现了 `SseMcpCreateStrategy`、`StdioMcpCreateStrategy` 和 **`LocalMcpCreateStrategy`**。 + - **反射与 Spring 容器**：**本地 MCP** 的核心是利用 Java 反射机制和 Spring 的 `ApplicationContext`。它根据配置的 `beanName` 和 `methodName` 直接查找并调用本地 Spring Bean 的方法，将其封装为 `FunctionCallback` 提供给 AI 模型。这使得 AI 可以直接调用本地业务代码（如查询数据库、发送邮件），无需走网络协议，**性能更高** 且 **开发更便捷**。 + +--- + +### 二、 并发编程与网络通信 (Netty) + +#### 4. 在“手机网关”模块中，Netty 服务端是如何解决 TCP 粘包/拆包问题的？通信协议是如何设计的？ +**参考答案：** +- **粘包/拆包解决方案**：使用了 Netty 自带的 **`LineBasedFrameDecoder`**。 + - **原理**：以换行符 `\n` 作为消息结束的标志。发送端在 JSON 数据后追加换行符，接收端的 Decoder 会自动根据换行符分割出完整的消息帧，从而解决 TCP 粘包和拆包问题。 +- **通信协议设计**：采用 **JSON 文本协议**。 + - **请求**：`{"type": "action", "command": "click", "x": 100, "y": 200}\n` + - **响应**：`{"type": "response", "status": "success", "data": "..."}\n` + - **优势**：协议简单，易于调试（人类可读），且 JSON 解析库成熟。 + +#### 5. Netty 是异步通信的，但业务层调用（如“让手机截图”）通常需要同步等待结果，你是如何实现的？ +**参考答案：** +- **核心机制**：使用了 JDK 的 **`CompletableFuture`** 实现 **异步转同步**。 +- **实现步骤**： + 1. **请求映射**：在发送指令前，创建一个 `CompletableFuture` 对象，并将其存入一个线程安全的 `ConcurrentHashMap`（Key 为请求 ID）。 + 2. **同步等待**：业务线程调用 `future.get(timeout)`，进入阻塞等待状态。 + 3. **异步回调**：当 Netty 的 `channelRead` 方法收到客户端响应时，根据响应中的 ID 从 Map 中取出对应的 `future`。 + 4. **唤醒线程**：调用 `future.complete(response)` 将结果填入，此时阻塞的业务线程会被唤醒并获取到结果。 + 5. **超时处理**：如果 `future.get()` 超时，抛出异常并从 Map 中移除该 Future，防止内存泄漏。 + +--- + +### 三、 AI 智能体编排与业务逻辑 + +#### 6. 请介绍一下项目中 Agent 工作流（Workflow）的设计，Loop、Parallel 和 Sequential 节点分别解决了什么问题？ +**参考答案：** +项目通过 `AgentWorkflowNode` 实现了类似 **LangChain** 或 **Google ADK** 的编排能力： +- **Sequential（串行编排）**： + - **场景**：任务之间有严格依赖关系。例如：`搜索信息` -> `整理摘要` -> `生成报告`。 + - **实现**：按顺序依次执行 List 中的 Agent，上一个 Agent 的输出作为下一个的输入。 +- **Parallel（并行编排）**： + - **场景**：任务独立且耗时，需要提高效率。例如：同时`搜索技术方案 A`、`搜索技术方案 B`、`搜索技术方案 C`，最后汇总对比。 + - **实现**：使用线程池并发执行多个 Agent，最后通过 `CountDownLatch` 或 `CompletableFuture.allOf` 等待所有任务完成并聚合结果。 +- **Loop（循环编排）**： + - **场景**：需要反复迭代直到满足条件。例如：`生成代码` -> `运行测试` -> `报错` -> `修正代码` -> `再运行测试`... 直到测试通过或达到最大重试次数。 + - **实现**：在 `LoopAgentNode` 中维护一个循环逻辑，根据 **评估函数（Evaluator）** 的结果决定是继续循环还是输出最终结果。 + +#### 7. 在“AI + Draw.io”场景中，如何确保 AI 生成的 XML 是可用的？前后端交互协议是如何设计的？ +**参考答案：** +- **质量控制（Reviewer Agent）**： + - 引入了 **多智能体协作（Multi-Agent System）** 机制。 + - 设计了专门的 **Reviewer（审查员）** 智能体。在 **Drawer（绘图员）** 生成 XML 后，Reviewer 会检查 XML 的语法正确性、连线逻辑（如是否交叉、是否有孤立节点）等。如果发现问题，Reviewer 会反馈给 Drawer 进行修正，直到通过审查。 +- **交互协议设计**： + - 定义了包含 `type` 字段的 JSON 协议： + - `type: "user"`：表示 AI 需要用户补充信息（如“请问您想要画什么类型的图？”），前端渲染为对话框。 + - `type: "drawio"`：表示 AI 生成了绘图数据，前端解析 XML 并调用 Draw.io 组件进行渲染。 + - `type: "review"`：表示正在审查中（可选，用于展示状态）。 + - **优势**：明确区分了 **对话交互** 和 **指令执行**，提升了用户体验。 + +#### 8. 你提到的“Spring AI 动态预热”是如何实现的？有什么作用？ +**参考答案：** +- **作用**： + - **快速响应**：AI 模型（尤其是加载了大量 Prompt 或上下文的模型）初始化较慢，预热可以避免用户第一次请求时的长延迟。 + - **配置校验**：在应用启动时尽早发现 API Key 错误、网络不通等配置问题，避免上线后报错。 +- **实现**： + - 利用 Spring 的 `ApplicationRunner` 或 `CommandLineRunner` 接口，在 Spring 容器启动完成后自动触发。 + - 读取配置文件中的 `warm-up` 列表，模拟一次简单的 AI 调用（如发送 "Hello"），强制初始化底层的 `ChatModel` 和 `Token` 连接池。 + +--- + +### 进阶与优化 (Spring AI/Skills/性能) + +#### 9. 在 Spring AI 集成中，项目是如何利用 "Skills" 机制来增强 RAG 或替代传统向量检索的？ +**参考答案：** +- **Skills 概念**：项目引入 `spring-ai-agent-utils`，将特定领域的知识（如 PDF 处理、系统巡检脚本）封装为 **Skills（技能书）**，这不仅仅是静态文本，还包含了可执行的代码逻辑（Tools）。 +- **与传统 RAG 对比**： + - **传统 RAG**：侧重于 **检索 (Retrieval)**，即从向量数据库中找到相关文本片段喂给 LLM。优点是知识覆盖面广，缺点是不仅准确率受限于检索算法，而且无法直接操作。 + - **Skills**：侧重于 **执行 (Action)**。它将“工具定义 + Prompt 模板 + 执行脚本（Python/Shell）”打包。Agent 识别到意图后，直接加载对应的 Skill 并执行脚本。 + - **优势**：减少了 LLM 的幻觉（执行逻辑是确定性的代码），缩短了 "Prompt -> 分析 -> 找工具 -> 执行" 的决策链路，对于特定任务（如“重启服务器”）比 RAG 更精准、更安全。 + +#### 10. 移动网关系统中，服务端如何处理 Netty 的异步通信与 Agent 同步决策之间的矛盾？ +**参考答案：** +- **矛盾点**：Netty 是基于事件驱动的异步框架，而 Agent 的思维链（Chain of Thought）通常是线性的、同步等待每一步结果的（例如：点击按钮 -> 等待截图 -> 分析截图 -> 下一步）。 +- **实现机制**： + - **Future 模式**：服务端维护一个 `Map> pendingResponses`。 + - **同步等待**：Agent 线程在发送指令后，调用 `future.get(timeout)` 阻塞等待。 + - **异步唤醒**：Netty 的 Handler 收到手机端响应后，根据 ID 从 Map 中取出对应的 Future，调用 `future.complete(response)`。 + - **异常处理**：设置超时时间（如 30秒），防止因手机端无响应导致 Agent 线程永久阻塞。 + +#### 11. 项目在装配 MCP (Model Context Protocol) 工具时使用了什么设计模式？解决了什么问题？ +**参考答案：** +- **设计模式**：使用了 **策略模式 (Strategy Pattern)** 配合 **工厂模式 (Factory Pattern)**。 +- **解决痛点**：在 `ChatModelNode` 中，如果使用大量的 `if-else` 来判断是创建 SSE 客户端、Stdio 客户端还是本地 Bean 调用，代码会非常臃肿且难以维护。 +- **实现细节**： + - 定义了 `ToolMcpCreateService` 策略接口。 + - 实现了 `SseMcpCreateStrategy`、`StdioMcpCreateStrategy`、`LocalMcpCreateStrategy` 等具体策略类。 + - 工厂类 `DefaultMcpClientFactory` 根据配置自动分发请求到对应的策略实现，从而实现了代码的 **开闭原则（Open/Closed Principle）**——新增一种协议只需增加一个策略类，无需修改原有逻辑。 + +#### 12. 针对智能体服务的异常处理，项目采用了怎样的分层处理策略？如果 Netty 服务端突然宕机，如何保证 Agent 任务的一致性？ +**参考答案：** +- **分层异常处理**： + - **Trigger 层**：`AgentServiceController` 使用 `try-catch` 全局捕获异常，并封装为统一的 `Response` 对象（包含错误码和提示信息），确保前端总是收到合法的 JSON 响应。 + - **Service 层**：业务逻辑中抛出自定义 `AppException`（如 `E0001` 智能体不存在），由上层统一处理，避免将底层堆栈信息直接暴露给用户。 +- **宕机恢复方案（进阶）**： + - **现状**：目前架构中 `CompletableFuture` 存储在内存中，宕机会导致任务丢失。 + - **优化思路**：引入 **持久化状态机（State Machine）**。在下发指令前，将 Task 状态（如 `PENDING_SCREENSHOT`）写入 Redis 或数据库。服务重启后，通过 Session ID 恢复上下文，或者手机端实现 **断线重连（Heartbeat）** 机制，重连后主动上报当前状态，Agent 根据最新截图重新规划后续步骤。 + +--- + +### AI Agent 核心八股文 (概念与原理) + +#### 13. 什么是 AI Agent（智能体）？它与传统的 LLM 应用（如 ChatGPT）有什么本质区别？ +**参考答案：** +- **AI Agent 定义**：AI Agent 是一个能够感知环境、进行推理规划、主动调用工具并采取行动以实现目标的智能系统。它具备 **感知（Perception）**、**大脑（Brain/LLM）**、**规划（Planning）** 和 **行动（Action/Tools）** 四大核心组件。 +- **与传统 LLM 区别**： + - **被动 vs 主动**：ChatGPT 等 LLM 应用通常是 **被动响应** 用户输入的（Input -> Output），无状态且单次交互。而 AI Agent 具备 **主观能动性**，它能将复杂目标拆解为一系列子任务，并主动调用工具（如搜索、API、代码执行）来获取信息或改变环境状态。 + - **工具使用能力**：传统 LLM 仅依赖训练数据（内部知识），存在幻觉且无法获取实时信息。Agent 通过 **Function Calling** 或 **MCP** 协议连接外部世界（Google、数据库、API），极大地扩展了能力边界。 + - **循环迭代**：Agent 通常采用 **ReAct (Reasoning + Acting)** 范式，即“思考 -> 行动 -> 观察结果 -> 再思考”，形成一个闭环，直到目标达成。 + +#### 14. 什么是 ReAct 范式？它是如何让 Agent 具备推理能力的？ +**参考答案：** +- **概念**：ReAct 是 **Reasoning（推理）** 和 **Acting（行动）** 的组合。它是一种 Prompt Engineering 技术，要求 LLM 在执行具体动作前，先生成一段“思维链（Thought）”。 +- **工作流程**： + 1. **Thought（思考）**：LLM 分析当前任务，决定下一步该做什么（例如：“我需要先搜索一下今天的日期”）。 + 2. **Action（行动）**：LLM 生成调用工具的指令（例如：`SearchTool.search("current date")`）。 + 3. **Observation（观察）**：工具执行并返回结果（例如：“2023-10-27”）。 + 4. **Repeat（循环）**：LLM 根据观察结果进行下一轮思考，直到得出最终答案（Final Answer）。 +- **优势**：相比直接生成答案（Zero-shot），ReAct 显著减少了幻觉，增强了解决复杂多步问题的能力，并提供了可解释的推理过程。 + +#### 15. 请解释 RAG（检索增强生成）与 Fine-tuning（微调）的区别及各自适用场景。 +**参考答案：** +- **RAG (Retrieval-Augmented Generation)**： + - **原理**：类似于“开卷考试”。在 LLM 生成答案前，先从外部知识库（向量数据库）中检索相关文档片段，作为上下文（Context）拼接到 Prompt 中喂给 LLM。 + - **适用场景**：需要**实时更新知识**（如新闻）、**私有数据查询**（如企业文档）、**降低成本**（无需训练模型）的场景。 + - **优缺点**：成本低、无遗忘问题，但受限于检索精度和 Context Window 长度。 +- **Fine-tuning (微调)**： + - **原理**：类似于“复习内化”。使用特定领域的数据集对预训练模型进行进一步训练，调整模型参数，使其掌握特定领域的知识或风格。 + - **适用场景**：需要**特定格式输出**（如代码生成、JSON提取）、**特定领域深度理解**（如医疗诊断）、**降低延迟**（无需检索）的场景。 + - **优缺点**：效果好、响应快，但成本高、知识更新困难（需重新训练）。 + +#### 16. 什么是向量数据库（Vector Database）？它在 AI Agent 中起什么作用？ +**参考答案：** +- **定义**：专门用于存储和检索高维向量（Vector / Embedding）的数据库。它支持 **近似最近邻搜索（ANN）**，能快速找到与查询向量距离最近的数据。 +- **Embedding（嵌入）**：将文本、图片、音频等非结构化数据转化为数字向量的过程。语义相似的内容，其向量在空间中的距离更近（如 Cosine Similarity）。 +- **在 Agent 中的作用**： + - **长期记忆（Long-term Memory）**：Agent 可以将对话历史、用户偏好存储在向量库中，实现跨会话记忆。 + - **知识库检索（Knowledge Base）**：存储海量文档片段，供 RAG 检索使用，弥补 LLM 训练数据的滞后性。 + +#### 17. 什么是 Chain of Thought (CoT)？它如何提升 LLM 的推理能力？ +**参考答案：** +- **概念**：思维链（Chain of Thought）是一种通过引导 LLM 生成**中间推理步骤**来解决复杂问题的技术。 +- **原理**：对于数学题或逻辑推理题，如果直接问答案，LLM 容易出错。但如果提示它“**Let's think step by step（让我们一步步思考）**”，或者在 Few-shot 示例中展示推理过程，LLM 就会模仿这种思维方式，将大问题拆解为小问题逐个击破。 +- **类型**： + - **Zero-Shot CoT**：仅添加提示词 "Let's think step by step"。 + - **Few-Shot CoT**：在 Prompt 中提供包含推理步骤的示例（）。 +- **价值**：显著提升了 LLM 在算术、常识推理和符号推理任务上的准确率，是 Agent 实现复杂规划的基础。 + +#### 18. 什么是 MCP (Model Context Protocol)？为什么它对 Agent 生态很重要？ +**参考答案：** +- **定义**：MCP 是一个开放标准协议，用于标准化 AI 模型与外部数据/工具的连接方式。它定义了统一的接口规范，使得工具（Tools）、资源（Resources）和提示（Prompts）可以跨平台、跨模型复用。 +- **核心价值**： + - **去碎片化**：解决了每个 AI 应用都需要为 Google Drive、Slack、GitHub 等写独立连接器（Connector）的问题。MCP 提供了统一的“插座”。 + - **即插即用**：开发者只需编写一次 MCP Server，任何支持 MCP 的 Client（如 Claude Desktop、Cursor、IDEA）都可以直接使用该工具。 + - **安全性**：通过标准化的鉴权机制（如 SSE + Token）管理数据访问权限。 diff --git a/docs/md/project/ai-agent-scaffold/part-0/mobile-openclaw.md b/docs/md/project/ai-agent-scaffold/part-0/mobile-openclaw.md new file mode 100644 index 000000000..478d0fc9b --- /dev/null +++ b/docs/md/project/ai-agent-scaffold/part-0/mobile-openclaw.md @@ -0,0 +1,62 @@ +--- +title: 手机小龙虾，这次我比小米下手早！ +lock: no +--- + +# 手机小龙虾，这次我比小米下手早！ + +作者：小傅哥 +

+ +
+ +综上所述，构建一个完整的智能体，需要综合运用上述所有技术和能力。为了统一标准、提升易用性，就很需要搭建一套统一的 AI Agent 智能体开发脚手架，剔除重复且复杂的工作环节，帮助业务快速融合并高效开展智能体开发。 \ No newline at end of file diff --git "a/docs/md/project/ai-agent-scaffold/part-1/\347\254\2541-2\350\212\202\357\274\232\347\263\273\347\273\237\346\236\266\346\236\204\350\256\276\350\256\241.md" "b/docs/md/project/ai-agent-scaffold/part-1/\347\254\2541-2\350\212\202\357\274\232\347\263\273\347\273\237\346\236\266\346\236\204\350\256\276\350\256\241.md" new file mode 100644 index 000000000..8eab70477 --- /dev/null +++ "b/docs/md/project/ai-agent-scaffold/part-1/\347\254\2541-2\350\212\202\357\274\232\347\263\273\347\273\237\346\236\266\346\236\204\350\256\276\350\256\241.md" @@ -0,0 +1,30 @@ +--- +title: 【更】第1-2节：系统架构设计 +pay: https://t.zsxq.com/sSD6u +--- + +# 《AI Agent 脚手架》第1-2节：系统架构设计 + +作者：小傅哥 +

+ +- 首先，在有了前面的内容学习后，我们了解到 RunnerNode 会做 InMemoryRunner 的构建，而这个对象的构建是需要拿到 SequentialAgentNode 作为最后一个节点，构建的 SequentialAgent 写入到上下文，到 RunnerNode 节点使用。它的核心本质是拿到 InMemoryRunner 创建的时候，所需 Agent 智能体。 +- 之后，这个 Agent 智能体，不非得以一个固定的写死，而是可以在配置文件中添加以 runner 配置，指定装配到 runner 中的 agent 名称。之后在 RunnerNode 构建 InMemoryRunner 的时候，则从上下文通过智能体名称获取 agent 装配进来即可。 +- 最后，思考下，AgentWorkflowNode 什么时候流转，这个流转则是根据当前 agentWorkflows 是不为空了，为空则直接流转到 RunnerNode 即可。RunnerNode 会根据配置的关联 agentName 进行配置。`这部分看代码的yml文件会更加清晰` diff --git "a/docs/md/project/ai-agent-scaffold/part-2/\347\254\2542-13\350\212\202\357\274\232\345\242\236\345\274\272\350\243\205\351\205\215-AgentWorkflowNode.md" "b/docs/md/project/ai-agent-scaffold/part-2/\347\254\2542-13\350\212\202\357\274\232\345\242\236\345\274\272\350\243\205\351\205\215-AgentWorkflowNode.md" new file mode 100644 index 000000000..144a44533 --- /dev/null +++ "b/docs/md/project/ai-agent-scaffold/part-2/\347\254\2542-13\350\212\202\357\274\232\345\242\236\345\274\272\350\243\205\351\205\215-AgentWorkflowNode.md" @@ -0,0 +1,417 @@ +--- +title: 【更】第2-13：增强装配-AgentWorkflowNode +pay: https://t.zsxq.com/qjhUb +--- + +# 《AI Agent 脚手架》第2-13：增强装配-AgentWorkflowNode + +作者：小傅哥 +

+ +
+ +- 左侧是旧版流程，LoopAgentNode、ParallelAgentNode、SequentialAgentNode，每个节点交叉流转。这次换到新版流程，所有的流转都由 AgentWorkflowNode 负责。这样会让三个功能 Agent 节点的职责更为清晰。 +- 这样，AgentWorkflowNode 就成了分发中心，三个 LoopAgentNode、ParallelAgentNode、SequentialAgentNode 智能体节点处理完业务后都回到 AgentWorkflowNode 即可。 + +## 三、功能实现 + +### 1. 工程结构 + +
+ +
+ +- 修改 LoopAgentNode、ParallelAgentNode、SequentialAgentNode，三个节点中的流转操作，都转移到 AgentWorkflowNode 处理。 +- 在 AgentWorkflowNode 中，要拿到当前 agentWorkflows 配置的列表中，步骤中第N个，把拿到的值作为当前的信息存储到上下文，之后流转到任何一个节点，只负责从上下文取到当前值即可。 + +### 2. 核心模块 + +#### 2.1 定义上下文 + +```java +@Data +@Builder +@AllArgsConstructor +@NoArgsConstructor +public static class DynamicContext { + + /** + * LLM API + */ + private OpenAiApi openAiApi;

+ +
+ +- 首先，需要结合 [react-drawio](https://github.com/marcveens/react-drawio) 插件，把 draw.io 嵌入到 react 程序里。在 react-drawio 的插件里，提供了相关的 API 操作，这可以让我们把 ai 生成的 xml 文件，让 draw.io 渲染出来。也可以读取到 draw.io 上的内容，再发给 ai 进行分析和调整。 +- 之后，是 ai agent 脚手架开发的程序，编写智能体提示词，让其可以以 xml 的格式返回。当然这部分也可以做一些限定，比如返回的数据是一个带有类型和内容的对象，如果类型 type 是对话，那么可以进行多次交流，如果返回类型是 xml，那么则直接渲染。目前的案例程序，会先直接返回 xml 直接渲染进来。 +- 最后，我们做这类内容，我们先有一个简单的清晰的流程和实现方案，能把整个流程串联起来。当你做的透彻以后，就可以继续扩展迭代功能了。 diff --git "a/docs/md/project/ai-agent-scaffold/part-4/\347\254\2544-1\350\212\202\357\274\232\345\210\235\345\247\213\345\214\226\345\267\245\347\250\213\346\220\255\345\273\272.md" "b/docs/md/project/ai-agent-scaffold/part-4/\347\254\2544-1\350\212\202\357\274\232\345\210\235\345\247\213\345\214\226\345\267\245\347\250\213\346\220\255\345\273\272.md" new file mode 100644 index 000000000..48d967c17 --- /dev/null +++ "b/docs/md/project/ai-agent-scaffold/part-4/\347\254\2544-1\350\212\202\357\274\232\345\210\235\345\247\213\345\214\226\345\267\245\347\250\213\346\220\255\345\273\272.md" @@ -0,0 +1,28 @@ +--- +title: 【更】第4-1节：初始化工程搭建 +pay: https://t.zsxq.com/PDeYZ +--- + +# 《AI Agent 场景应用 - ai draw.io》第4-1节：初始化工程搭建 + +作者：小傅哥 +

视频：[https://t.zsxq.com/DcL2p](https://t.zsxq.com/DcL2p) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +**25年3月初**，小傅哥，带着大家开启了 DeepSeek RAG、MCP 项目，随后兴起 MCP 服务提供的热潮，包括；支付宝、百度、高德，等等大厂开启了 MCP 服务计划。直至现在，市面上已经有了场景非常丰富的 MCP 服务。**那些第一波跟着小傅哥学习的伙伴，早早的让简历上多了一笔 MCP 服务开发和使用的经验！** + +
+ +
+ +**接下来，小傅哥将带着小伙伴，再往前多走一步！** + +RAG 教了，MCP 搞了，那么现在是时候，实现一套自动化的 Ai Agent 服务了。 + +如图，以通过数据库表动态配置的手段，完成相关物料的加载，包括；`模型（gpt-4.1/deepseek）`、`客户端`、`对话预设`、`执行规划（Planning）`、`顾问（记忆、RAG、日志）`、`工具（MCP`）等，在把单个 Client 串联，完成整个 Agent 调用链。这样一个 Agent 调用链可以以对话形式使用或通过 Agent 动态任务自动执行。 + +
+ +
+ +这套项目，小傅哥为它干了`1.87万`行代码（前后端），`14张`数据库表，全程动态化构建模块 Bean 对象，预热装配 Agent 服务。达到随用随配，自主组建出想要的各类的 Agent 功能服务。就以现在的丰富的 MCP 市场来可以说是，广阔天地，大有可为！在这套项目架构下，可以扩展出非常多的东西。 + +接下来，小傅哥就给大家，细致的介绍下这套项目，以及截图演示运行效果。 + +> 🧧 文末提供了全套 AI、RAG、MCP、Agent 项目、开发教程以及工程源码。此外还有非常多的互联网大厂项目（17个），都可以一并获取学习。 + +## 一、项目演示 + +这套项目的功能非常强大，全部都以 Agent 方式进行通信。所有的 Agent 都可以动态化配置，解耦的非常强👍🏻。接下来，小傅哥给大家演示下使用效果。 + +### 1. 前端页面 + +
+ +
+ +- 首先，我为智能对话体（MCP）配置了联网、CSDN自动发帖、文件操作服务。 +- 之后，我们可以通过预设的提示词模板，来调用对应的 MCP 服务，也可以多个 MCP 一起调用。如联网检索文章、生成解答，发布到论坛，在把文章名称记录到本地文件。这一系列操作都是可以的。 +- MCP 服务平台； + + - https://mcpfound.cc/ + - https://mcp.so/ + - https://sai.baidu.com/mcp + +> 结合知识库、MCP、提示词规划、上下文记忆，可以有非常多的场景可以玩。后续小傅哥还会继续分享可玩场景。 + +### 2. 后台页面 + +#### 2.1 配置智能体（动态预热） + +
+ +
+ +#### 2.2 动态任务 + +
+ +
+ +- 系统会自动的把任务加载到系统内执行，完成智能体的调用。 +- 有了这个操作，你配置好的智能体，他就可以连续24小时的工作了。除了自动发文章，你可以配置出各种东西。比如特朗普推特、黄金、股票价格，每天早上出一个文件，邮件方式推送给自己。兼职美滋滋。 + +#### 2.3 MCP管理 + +
+ +
+ +- 市面上有非常的多的 MCP 服务，我们可以选择的这些服务来组装出我们的智能体。 +- 系统支持配置 stdio、sse，两种方式。无论是自己开发的 MCP 还是市面的都可以使用。（课程中有教大家，基于 Spring AI 怎么开发 MCP 服务） + +## 二、系统设计 + +### 1. 功能流程 + +
+ +
+ +- 如图，从上往下，以任务或会话方式，调用 agent 为目标，串联各个 client。形成内部处理 a2a 流程。 +- 之后，对于 client 则由系统都动态的方式创建 bean 对象。运营在 ai agent 后台配置相关数据即可。 + +### 2. 库表设计 + +
+ +

课程：[https://t.zsxq.com/GwNZp](https://t.zsxq.com/GwNZp) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主小傅哥。 + +刚上周，老板说：`”把咱们招聘里也加一条，具备AI应用开发能力的优先！“`。是呀，现在越来越多的企业都在用AI开发能力提效了，如；聊天软件增加一键唯独信息归档提取、工作文档资料携AI对话分析、工程SQL语句脚本辅运营自动完成数据处理、代码编写用AI完成自动评审等等。这些都是在AI的基础上在构建应用，以后也会越来越多！所以，具备AI应用开发能力，也是每个工程师最应该具备的基础能力了。 + +并且用不了多久，各大互联网企业都将大量的推进落地，自有 [MCP](https://github.com/modelcontextprotocol) 服务的实现，用于增强企业 AI 应用的提效能力。因为 [MCP](https://github.com/modelcontextprotocol) 的加入，可以让你；一条命令`帮研发`，调用应用系统日志、排查系统CPU负载、自主选择是否调度数据库信息。也可以一条命令`帮运营`，搞定复杂的SQL执行、导出报表、分析数据、完成促活营销券的自动化配置上架。这就是 [MCP](https://github.com/modelcontextprotocol) 的魅力！👍🏻 + +
+ +
+ +**那么牛，MCP 是什么？** + +专业的术语 `MCP = Model Context Protocol` 模型上下文协议，可实现应用与外部数据源和工具之间的无缝集成。无论您是构建 AI 驱动的 IDE、增强聊天界面还是创建自定义 AI 工作流，MCP 都提供了一种标准化的方式来连接他们所需的上下文。 + +`来吧，上图！让你看看它是啥！` + +
+ +
+ +- 首先，站在用户的使用视角，研发或者运营，可以通过话术描述，完成系列的 AI 工作流，并拿到最终的结果。这就是 MCP 最终为你提供的服务。 +- 那么，你可以想象，在日常的工作中，运营、研发、产品、测试等，都有非常多的重复非创作性的工作，占用了大量的时间成本。尤其是研发，写写代码，就有运营过来，帮我查个问题吧，小嘚嘚。但如果有这样的借助于 MCP 实现的 AI 工作流，就可以完成80%以上的工作量。 +- 之后，站在技术的实现视角，MCP 是一个标准结构框架，你可以按照它（Spring AI）提供的 SDK 开发方式，完成本地化 API 的接入开发。让 AI 有明确的方式调用各类 API 服务接口。如果没有 MCP 这会是一件很麻烦的事情。 + +**跟着小傅哥学习，从不走偏！😄** + +- 2022年底，ChatGPT 开始火爆。 +- 2023年2月，小傅哥，开启了第一个基于AI的项目，ChatGPT AI 问答助手项目。让所有伙伴，都能学习到 AI 如何开发应用。 +- 2023年4月，启动OpenAI(ChatGPT/ChatGLM)微服务应用体系构建大型项目，让大家可以用微信登录、微信支付/蓝兔支付，构建自己的可对外付费提供服务的 OpenAI。这一年上车学习的伙伴，很多做了自己的 AI 产品，除了提高编程技能，又小赚了一辆宝马。 +- 2024年7月，结合企业诉求，开启 OpenAI + Github Acitons，实现代码自动化评审。这一年，不少伙伴在自己的公司中都有落地，个人也得到了述职晋升。 +- 2025年3月，咱们再起启航，基于 Ollama 部署 DeepSeek，开发 RAG 知识库，解析文档和Git仓库代码。这个东西，将是企业中构建自己知识库的又一项非常重要的事情。有了知识库，AI 代码的自动评审，会更加精准，也可以辅助分析需求等。 + +那么，接下来小傅哥就细致的介绍下，本次开启的新项目，可以让大家学习到哪些知识，掌握哪些技术。 + +> Spring AI MCP 与 24年末发布，学习此 AI 应用开发项目，你将是第一批具备 Java AI 应用实战开发能力的人。竞争力，嘎嘎滴！ + +## 一、能学到啥 + +这是一套综合`前后端 + Dev-Ops`，基于 Spring Ai 框架实现，Ai Agent 智能体。耗时7个多月，38节课程（`视频`+`文档`），从 RAG 到 MCP，再实现出互联网企业级，可编排的 Ai Agent 智能体，现已全部开发完成 + 部署上线。💐 + +该项目是结合当下最火的 Ollama、DeepSeek、SpringAI 等技术构建的 RAG 知识库实现。从前端到后端到 dev-ops 的全栈式功能手把手实现。 + +- 前端，基于 AI 工具，设计前端对话页面，完成 HTML、JS、TailwindCSS 的编码工作。 +- 前端，配置跨域服务接口，前后端分离实现 UI + 服务端接口对接。 +- 后端，构建双层架构，直接面向需求编码。让学习伙伴更轻松完成 RAG 知识库核心知识的学习。 +- 后端，基于 Spring AI 完成 DeepSeek、OpenAI 双模型的策略对接，处理文本向量的解析和存储。 +- 后端，使用 postgresql 存储切割文本向量数据，完成知识库的解析和存储。 +- 后端，处理多样文本`（.md、.sql、.txt、.word...）`的解析储存以及Git克隆代码库遍历切割存储。 +- 后端，使用 Redis 存储知识库标签，用于检索展示使用。 +- 后端，基于 Flux 编写流式会话接口，以及增加知识库检索功能。 +- 运维，基于 Docker 部署 Ollama 环境，完成 DeepSeek 大模型配置。 +- 运维，使用 Linux、Docker、Nginx 完成项目的打包、构建、上线！ + +虽然，知识库都有很多现成的工具。但研发的能力不是在于功能应用，而是具备这样的开发技能储备，在有需要的时候，可以举手🙋🏻‍♀️”我会，我来做！“ + +> 此项目，全程视频手把手操作 + 全部的小册文档，你可以轻松上手学会这样一个项目！ + +## 二、项目介绍 + +这是一套基于 Ollama DeepSeek 大模型构建的增强 RAG 知识库检索项目，在这套项目上，实现了除普通文档知识解析外，增加了 Git 代码库的拉取和解析，并提供操作接口。为工程师做项目开发时，`需求分析`、`研发设计`、`辅助编码`、`代码评审`、`风险评估`、`上线检测`等，做工程交付提效。 + +
+ +
+ +### 第1期，RAG 我们做了什么 + +在 《DeepSeek RAG 增强知识库》第1阶段，基于 Spring AI 0.8.1 开发了一套可以上传文件和Git仓库进行解析、切割、存储，到使用向量库完成 AI 的知识库问答系统。并最终通过 Docker 部署上线。 + +#### 1. 对话页面 + +
+ +
+ +- 这是全程视频手把手，带着大家通过AI工具，完成的UI设计实现课程会演示这个操作），实现的一款非常简单漂亮的UI效果。 +- 我们可以结合知识库，进行更加有效的提问。像是公司中，会把知识库提供出一个标准接口，给其他各个AI应用平台提供能力。 + +#### 2. 上传知识 + +
+ +
+ +- 上传知识，可以解析不同类型的知识库。 +- 除了课程提供的文档库、代码库，你可以增加其他的知识库，如；网页的解析，与网页内容对话。让我们的UI，增加一个侧边栏，读取当前网页内容，分析对话。这样在公司中的一些工程的日志，错误分析时，可以更快的处理。 + +#### 3. 解析知识 - 后台日志 + +
+ +
+ +- 上传知识后，可以看到日志信息。 +- 一套工程作为知识库是非常具有开发价值的，在我们做提问的时候就不需要，人工的去分析工程，而是直接使用了。 + +### 第2期，MCP 我们要做什么 + +与第2期相比，第1期可以称之为小试牛刀，让小伙伴们以最快、最快的往事，积累，运用 Spring AI 框架，开发自己的 RAG 知识库。~~也是方便有些死鬼，早点写到简历上~~ + +到了第2期，你就开始吃上细糠了，小傅哥会带着你升级 Spring AI 框架为 1.0.0-M6 最新版本，多模型配置和操作 PG 向量库，使用 GPU 搭建响应速度更好的 Ollama DeepSeek 大模型（秒级处理），以及对接官网 DeepSeek 的大模型和统一 one-api 对接方式。 + +但这还只是开始，随着基础框架的升级完成，我们将进入 MCP 服务的开发实现。通过 AI 指令，完成 AI 工作流，调度各项 MCP 处理我们的任务作业。如图，举例操作； + +
+ +
+ +- 基于 MCP 服务的开发和对接，通过 AI 工作流指令，完成数据的采集和存放动作。💡 聪明的小伙伴以及开始联想，基于这样的 AI 开发，可以替代很多的日常工作啦。**没想到吧，也把自己替代了** 但仍然，蠢蠢欲动（我不做，别人也做呀）！~~实现后，晋升又有的讲啦！简历也有东西写啦！~~ +- 有了 MCP 后，相当于把我们需要；在一个网页操作数据库查询数据、打开另外一个网页看天气预报，再手动的创建个文件把以上的信息获取后，复制粘贴到文件里。这一些列操作，都让 AI 通过 MCP 模型上下文协议进行处理。也就是 AI 可以调用后台接口啦！ + +### 第3期，Agent 我们要做什么 + +RAG 教了，MCP 搞了，那么现在是时候，实现一套自动化的 Ai Agent 服务了。 + +如图，以通过数据库表动态配置的手段，完成相关物料的加载，包括；`模型（gpt-4.1/deepseek）`、`客户端`、`对话预设`、`执行规划（Planning）`、`顾问（记忆、RAG、日志）`、`工具（MCP`）等，在把单个 Client 串联，完成整个 Agent 调用链。这样一个 Agent 调用链可以以对话形式使用或通过 Agent 动态任务自动执行。 + +
+ +
+ +本项目分为，用户端、管理端和服务端，服务端统一提供接口能力，管理端维护 AI Agent 智能体配置、用户端提供使用服务。 + +#### 1. 登录界面 + +
+ +
+ +- 这一部分在数据库表增加了 admin_user 表，有配置登录账号和密码，可以简单做校验。 + +#### 2. 管理界面 + +
+ +
+ +- 管理后台目前提供了，代理管理（拖拉拽编排方式配置智能体），资源管理（model、client、mcp、advisor、prompt） +- 数据分析、系统设置，是样例，你可以继续扩展你所需要的内容。 + +#### 3. 代理管理 + +##### 3.1 代理列表 + +
+ +
+ +- 这里的代理列表，就是通过拖拉拽配置的智能体。可以点击【查看】看到明细，也可以【新建】，还可以删除。 +- 点击【加载】则是调用服务端，把数据加载到 Spring 容器，之后就可以使用了。 + +##### 3.2 代理配置 + +
+ +
+ +- 当你点击一个代理配置，则会展示出拖拉拽的数据到页面上。这部分会从数据库读取，之后展示出来，全部可视化。 +- 如果你点击了Save则会做出一份新的，之后对于旧的，你可以自己手动删除。 + +#### 4. 资源管理 + +
+ +
+ +- 资源管理下，是配置一个智能体所需的各项资源信息，你可以在这里进行维护。如，MCP 工具管理。 + +#### 5. 页面使用 + +##### 5.1 对话交流 + +
+ +
+ +##### 5.2 场景解析 + +
+ +
+ +##### 5.3 监控分析 + +
+ +
+ +- 配置后的智能体，可以在智能体选择里进行获取使用。之后进行提问。 +- 效果还不错，这里小傅哥验证了配置的智能体进行提问。 + +## 三、关于系统设计 + +本套系统设计，也是花费了非常大的心思。 + +### 1. 执行流程 + +
+ +
+ +在整个 Ai Agent 的实现中，小傅哥带着大家分析设计了4种方案，包括；固定执行的、循环执行的、智能分析决策的还有一个按照步骤规划的。这些流程都有适合于自己业务场景使用。在代码中也都有不同方案的实现，之后通过用户选择后进行动态化的策略调度。 + +### 2. 核心动作 + +#### 2.1 数据装配 + +
+ +
+ +- 首先，以构建 AiClientNode 的对话客户端为目的，已经完成了相关的元素实例化步骤。本节这里要处理的是，顾问角色的构建，以及构建 AiClientNode 节点。 +- 之后，AiClientNode 的构建，是关联了其他各项元素的，所以在构建时，需要在 AiClientNode 节点，从 Spring 容器通过 getBean 的方式，检索到对应的各项元素。 + +#### 2.2 动态调度 + +
+ +
+ +- 这里会根据用户的请求，进行策略路由，找到所需的 Ai Agent 执行策略进行处理。这里小傅哥也有意加入不同的策略，让大家可以看到很多的 Ai Agent 设计思路。 + +#### 2.3 执行策略（01） + +
+ +
+ +- 以程序启动为开始，进行自动化装配。这个过程我们先把一些想预先启动的数据库中的 agent 配置所需的 client 客户端进行服务初始化。之后写入到 Spring 容器，方便在执行 Agent 时进行使用。`前面有伙伴问，为什么把实例化的对象写入到 Spring 容器，这里就是原因` +- 客户端（UI），进行 POST 接口请求，这个过程需要封装一个 SSE 流式响应的接口，让 Step 1~4 各个执行步骤，把过程信息写入到流式接口。这里要注意，需要给接口返回的**对象**添加上对应的类型（什么步骤、什么节点、什么过程），以便于反馈给用户 Agent 在做什么。 + +#### 2.4 执行策略（02） + +
+ +
+ +- 这是其中的一种 Ai Agent 执行策略方式，通过用户的提问进行分析、规划、列出执行步骤，之后依次执行。 +- 所有的这些实现都有相应的代码，带着大家使用规则树框架清晰的实现出来。 + +## 四、课程目录 + +### 1. 课程目录 + +**第1阶段** spring-ai v0.8.1 - RAG 静态知识库（本阶段，需要配置附件的 setting.xml） + +- 第1节：关于 AI RAG 知识库项目介绍 +- 第2节：初始化知识库工程&提交代码 +- 第3节：Ollama DeepSeek 流式应答接口... +- 第4节：Ollama DeepSeek 流式应答页面... +- 第5节：Ollama RAG 知识库上传、解析和验证 +- 第6节：Ollama RAG 知识库接口服务实现 +- 第7节：基于AI工具，设计知识库UI和接口对接 +- 第8节：Git仓库代码库解析到知识库 +- 第9节：扩展OpenAI模型对接，以及完整AI对接 +- 第10节：云服务器部署知识库（Docker、Ngin... + +**第2阶段** spring-ai v1.0.0 - MCP 动态知识库 + +- 第11节：吃上细糠，升级SpringAI框架 +- 第12节：康庄大道，上手 AI MCP 工作... +- 第13节，道山学海，实现MCP自动发帖服务（... +- 第14节，海纳百川，上线MCP自动发帖服务 +- 第15节，川流不息，实现MCP微信公众号消息通知服务 +- 第16节：息息相通，MCP 服务部署上线（sse 模式） + +**第3阶段** spring-ai v1.0.0 - Ai Agent 进行中「如果着急面试，可以直接做3阶段，完成到13节很够面试啦」 + +- 第3-0节：Ai Agent 项目介绍和系统演示【最初版本，含完整代码】 +- 第3-1节，Ai Agent 业务流程、系统架构、库表设计说明 +- 第3-2节：初始化项目工程 +- 第3-3节：Ai Agent 测试案例 +- 第3-4节：根据 Ai Agent 案例，设计库表 +- 第3-5节：多数据源和Mapper配置 +- 第3-6节：数据加载模型设计 +- 第3-7节：动态实例化客户端API +- 第3-8节：动态实例化对话模型 +- 第3-9节：实例化对话客户端 +- 第3-10节：Agent执行链路分析 +- 第3-11节：Agent执行链路设计 +- 第3-12节：Agent服务接口和UI对接（第一版AutoAgent效果） +- 第3-13节，Agent-ELK日志分析场景 +- 第3-14节，Agent-Prometheus监控分析场景 +- 第3-15节：AgentFlow执行链路分析（扩展思路） +- 第3-16节：FlowAgent执行链路设计（扩展思路） +- 第3-17节：增加调度器策略执行Agent链路 +- 第3-18节：动态执行智能体任务 +- 第3-19节：拖拉拽编排数据存储 +- 第3-20节：Agent管理后台实现 +- 第3-21节：在云服务器部署上线 + +### 2. 编程环境 + +- JDK 17 ~ 21 +- Postgresql +- SpringBoot 3.2.3 - Spring AI 0.8.1 ~ 1.0.0+ +- Redis +- Docker +- Ollama + DeepSeek + GPU - +- RAG、MCP、Function Call + +课程包括文档 + 小册，全程视频带着做。课程地址：[https://t.zsxq.com/GwNZp](https://t.zsxq.com/GwNZp) + +> 综上，你可以看到此套项目的完整的介绍，这些也都是企业里非常实用的技能积累。有希望提高自己的编程能力和面试材料的，可以马上加入学习。 + +--- + +课程包括；视频、小册、1 对 1 答疑解惑、专属VIP项目交流群，并且提供简历编写模板结构的一条龙🐲服务。让你学习后，直接拉开与还在玩具项目其他人的差距，面试脱颖而出提高竞争力！！！ + diff --git a/docs/md/project/ai-knowledge/ext/ai-agent-auto.md b/docs/md/project/ai-knowledge/ext/ai-agent-auto.md new file mode 100644 index 000000000..95cbe407e --- /dev/null +++ b/docs/md/project/ai-knowledge/ext/ai-agent-auto.md @@ -0,0 +1,137 @@ +--- +title: Ai Agent VS 字节扣子？ +lock: no +--- + +# Ai Agent VS 字节扣子？ + +作者：小傅哥 +

+ +- 首先，我们要基于 [flowgram.ai](https://flowgram.ai/) 框架，开发自己需要的 Node 节点（后面会有代码说明，方便伙伴扩展）。这里增加了；task、agent、client、too-mcp、model。 +- 之后，在页面点击添加节点，并选择好每个节点，应该配置的属性信息，以及连接节点关系。 +- 最后，点击保存，他会给你一个json 对象，按照对象的结构，创建服务端接口即可接收和保存。（相关保存操作，会在后续课程中添加，如果有诉求可以先把前端代码下载下去，对照json开发接口即可） + +> 本套全段代码 [ai-agent-station-front](#) 已经添加到课程中，可以进入获取。地址：[https://t.zsxq.com/GwNZp](https://t.zsxq.com/GwNZp) + +## 二、怎么添加节点 + +### 1. 下载前端工程 + +首先，你要下载 [ai-agent-station-front](https://gitcode.net/KnowledgePlanet/ai-agent-station-front) 到本地使用 trae.ai 打开。如果没有提示你，要自己手动执行 npm install 初始化工程。 + +
+ +
+ +- 首先，[flowgram.ai](https://flowgram.ai/) 官网提供了各种案例，可以下载一个进行扩展。这里小傅哥就是下载好的一个，之后添加我们需要的节点。 +- 之后，docs 下的 ai-agent-station.sql 为的是让 ai 可以使用，自动创建 node 节点的（下文有演示）。 +- 另外，这里的代码，对于稍微有些 react 编码基础的伙伴，是可以非常方便看懂的。后端工程师，如果不懂也没关系，让 ai 来解答以及操作。 + +### 2. Ai 编码，添加节点 + +
+ +
+ +- 首先，下载一份国际版 trae.ai，这里有使用文档。[https://bugstack.cn/md/road-map/trae.html](https://bugstack.cn/md/road-map/trae.html) 使用 cursor 也可以，其实这东西，重要的就是好用的模型。 +- 之后，nodes 下是各种节点，我们可以拖拽一份让 ai 编码参考。并告诉ai，以哪个库表信息来编写新的节点。（有时候可能有问题，如果有问题，可以手动修改下） + +## 三、点击保存，查看json + +
+ +
+ +
+ +
+ +- 点击保存，就可以拿到节点和链接的关系数据了。这份数据是可以和数据库对应上。 +- 后续课程从0到1的实现过程中，会和后端接口联动，存储数据。现在你也可以先下载前端代码，尝试编码。 + diff --git a/docs/md/project/ai-knowledge/ext/ai-agent-job.md b/docs/md/project/ai-knowledge/ext/ai-agent-job.md new file mode 100644 index 000000000..01634d737 --- /dev/null +++ b/docs/md/project/ai-knowledge/ext/ai-agent-job.md @@ -0,0 +1,97 @@ +--- +title: 阶段性总结，Ai Agent 的重要性 +lock: no +--- + +# 阶段性总结，Ai Agent 的重要性 + +作者：小傅哥 +

Agent设计模式在你们项目中是如何体现的？ + +**回答**：我们的Agent设计模式主要体现在多层次的智能体架构设计上。首先是**策略模式**的应用，通过IExecuteStrategy接口定义执行策略，AutoAgentExecuteStrategy实现自动执行逻辑；其次是**责任链模式**的核心应用，我们设计了四步执行链：RootNode→Step1AnalyzerNode（任务分析）→Step2PrecisionExecutorNode（精准执行）→Step3QualitySupervisorNode（质量监督）→Step4LogExecutionSummaryNode（执行总结），每个节点继承AbstractExecuteAutoSupport并实现特定的业务逻辑；再次是**工厂模式**，通过DefaultAutoAgentExecuteStrategyFactory创建执行策略处理器，管理DynamicContext动态上下文；最后是**模板方法模式**，AbstractExecuteAutoSupport定义了执行模板，各个Step节点实现具体的doApply方法。这种设计实现了"问题分析→自主规划→精准执行→质量监督"的完整AI Agent执行循环，每个步骤都可以独立配置不同的ChatClient、Prompt和Advisor，真正实现了智能体的可编排和可扩展。 + +### 4. Spring AI中的Advisor顾问角色是如何设计和实现的？ + +**回答**：Advisor顾问角色是我们AI Agent的核心能力之一，主要负责上下文记忆和知识库访问。我们实现了两种主要的Advisor：PromptChatMemory用于维护对话历史，通过maxMessages参数控制记忆长度；RagAnswerAdvisor用于访问向量知识库，通过topK和filterExpression参数控制检索精度。在实现上，我们继承了Spring AI的BaseAdvisor，重写了aroundCall方法来拦截对话请求，在请求前注入相关上下文信息，在响应后更新记忆状态。这种设计让AI Agent具备了持续学习和知识积累的能力，大大提升了对话的准确性和连贯性。 + +### 5. RAG知识库的分词和向量化是如何设计的？ + +**回答**：我们的RAG知识库基于PGVector实现，使用OpenAI的Embedding模型进行向量化。在分词策略上，我们使用TokenTextSplitter按照token数量进行智能分割，既保证了语义的完整性又控制了向量的维度。向量存储采用1536维的向量空间，支持余弦相似度检索。在数据预处理阶段，我们会对上传的文档进行清洗和标准化，提取关键信息并添加元数据标签，这些标签可以用于后续的过滤检索。检索时通过SearchRequest配置topK参数控制返回结果数量，通过filterExpression进行精确过滤，确保检索结果的相关性和准确性。 + +### 6. MCP协议的设计理念和实现方式是什么？ + +**回答**：MCP（Model Context Protocol）是我们实现工具调用的核心协议，它定义了AI模型与外部工具之间的标准化通信接口。我们支持两种通信方式：stdio模式适用于本地工具调用，通过标准输入输出进行通信；sse模式适用于远程服务调用，通过Server-Sent Events实现实时通信。在实现上，我们为每个MCP服务定义了标准的Function接口，使用@Tool注解标记可调用的方法，通过MethodToolCallbackProvider将Java方法暴露为MCP工具。比如微信通知MCP通过WeiXinNoticeService提供消息推送能力，CSDN发帖MCP提供自动发布文章的能力。这种设计让AI Agent能够调用各种外部服务，大大扩展了智能体的能力边界。 + +### 7. 你们是如何实现AI Agent的动态编排和热部署的？ + +**回答**：我们通过Spring的动态Bean注册机制实现了AI Agent的热部署能力。核心思路是将AI Agent的各个组件（Model、Prompt、Advisor、MCP）抽象为可配置的Bean，存储在数据库中。当配置发生变化时，通过ArmoryCommandEntity触发重新装配流程，使用DefaultArmoryStrategyFactory的策略模式动态创建新的组件实例，然后通过registerBean方法将新组件注册到Spring容器中。整个过程采用责任链模式，依次执行AiClientApiNode、AiClientModelNode、AiClientAdvisorNode、AiClientNode等节点，确保组件的正确装配顺序。这种设计让我们能够在不重启服务的情况下，动态调整AI Agent的能力配置，大大提升了系统的灵活性和运维效率。 + +### 8. 智能体任务调度服务是如何设计的，如何实现自动化巡检？ + +**回答**：我们基于Spring TaskScheduler扩展实现了智能体任务调度服务，支持定时和事件驱动两种触发方式。定时巡检通过Cron表达式配置执行周期，自动收集系统指标、日志信息、告警数据等，然后调用专门的巡检Agent进行智能分析，最终生成HTML格式的巡检报告。事件驱动巡检则监听MQ消息，当收到告警信息时立即触发相应的巡检动作。在实现上，我们为每种巡检场景配置了专门的Agent，比如性能巡检Agent配置了Prometheus MCP工具，日志巡检Agent配置了ELK MCP工具。巡检结果会通过微信公众号MCP自动推送给相关人员，实现了从发现问题到通知处理的全自动化流程。 + +### 9. 你们的MCP服务是如何保证安全性的？ + +**回答**：我们设计了通用的MCP Nginx Token校验机制来保证数据传输安全性。首先在Nginx层配置了统一的鉴权模块，所有MCP请求都需要携带有效的Token才能通过；Token采用JWT格式，包含用户身份、权限范围、过期时间等信息；在应用层，我们为每个MCP服务配置了独立的访问密钥，支持定期轮换；对于敏感操作如数据库访问、文件操作等，还增加了二次验证机制。此外，我们还实现了请求频率限制、IP白名单、操作审计日志等安全措施。在数据传输过程中，所有敏感信息都进行了加密处理，确保即使在网络传输过程中被截获也无法直接使用。 + +### 10. 前端的拖拽编排功能是如何实现的？ + +**回答**：我们基于React和flowgram.ai框架实现了AI Agent的可视化编排功能。前端采用节点式的流程图设计，每个节点代表一个AI Agent组件，用户可以通过拖拽的方式组合不同的Model、Prompt、Advisor、MCP组件。在技术实现上，我们使用React Flow作为基础图形引擎，自定义了各种组件节点的渲染逻辑；通过Context API管理全局状态，实时同步编排配置；使用WebSocket与后端保持连接，支持实时预览和调试。当用户完成编排后，前端会将配置信息序列化为JSON格式发送给后端，后端解析配置并动态创建对应的AI Agent实例。这种设计让非技术人员也能够轻松配置和使用AI Agent，大大降低了使用门槛。 + +### 11. 在实现多模型适配时遇到了什么挑战，是如何解决的？ + +**回答**：最大的挑战是不同AI模型的API格式和调用方式差异很大，直接适配会导致代码耦合度过高。我们的解决方案是引入one-api服务作为统一的模型网关，将所有第三方模型的API统一转换为OpenAI格式。在系统内部，我们只需要适配OpenAI的接口规范，通过配置不同的baseUrl和apiKey就能接入各种模型。同时我们还自研了SDK组件，封装了模型调用的通用逻辑，包括重试机制、超时处理、错误码转换等。这种设计不仅简化了开发复杂度，还提升了系统的稳定性和可扩展性，当需要接入新模型时只需要在one-api层配置即可。 + +### 12. 大规模并发场景下，AI Agent的性能是如何保证的？ + +**回答**：我们从多个维度进行了性能优化。首先是连接池管理，为每个模型API配置了独立的连接池，避免相互影响；其次是异步处理，所有AI调用都采用异步方式，通过ResponseBodyEmitter实现流式响应，用户可以实时看到AI的思考过程；然后是缓存策略，对于相同的问题我们会缓存AI的回答，减少重复计算；在资源调度上，我们使用自定义的线程池进行任务分发，根据任务类型和优先级进行智能调度。此外，我们还实现了熔断降级机制，当某个模型服务不可用时自动切换到备用模型，保证服务的高可用性。通过这些优化，我们的系统能够支持数千并发用户同时使用。 + +### 13. 如何保证AI Agent执行过程中的数据一致性？ + +**回答**：我们采用了事件驱动架构来保证数据一致性。每个AI Agent的执行过程被拆分为多个步骤，每个步骤完成后都会发布相应的事件，下一个步骤监听事件后开始执行。在数据库层面，我们使用了分布式事务来保证跨服务的数据一致性，关键操作都包装在事务中执行。对于长时间运行的AI任务，我们实现了断点续传机制，将执行状态持久化到数据库，即使服务重启也能从断点继续执行。同时我们还建立了完善的监控和告警机制，实时监控AI Agent的执行状态，一旦发现异常立即进行人工干预。这种设计确保了即使在复杂的业务场景下，数据的一致性和完整性也能得到保证。 + +### 14. 这个AI Agent系统给公司带来了什么实际价值？ + +**回答**：我们的AI Agent系统在多个方面为公司创造了显著价值。在开发效率方面，代码评审Agent将人工评审时间从平均2小时缩短到15分钟，准确率达到95%以上；在运维效率方面，智能巡检Agent实现了7×24小时自动监控，故障发现时间从小时级缩短到分钟级，运维人员的重复性工作减少了80%；在内容创作方面，文章生成Agent帮助技术团队每月自动产出50+篇高质量技术文章，大大提升了公司的技术影响力。更重要的是，这套系统的可编排特性让我们能够快速响应新的业务需求，从需求提出到Agent上线的周期从原来的2周缩短到2天，大大提升了业务响应速度。 + +### 15. 在项目推广过程中遇到了什么阻力，是如何解决的？ + +**回答**：最大的阻力来自于用户对AI准确性的担忧和使用习惯的改变。为了解决这个问题，我们采用了渐进式推广策略。首先选择了代码评审这个相对低风险的场景进行试点，通过大量的测试数据证明AI的准确性；然后我们设计了人机协作的工作模式，AI负责初步分析，人工负责最终决策，让用户逐步建立信任；在用户体验方面，我们提供了详细的操作文档和培训视频，还建立了用户反馈机制，根据用户建议持续优化产品功能。经过3个月的推广，用户接受度从最初的30%提升到了85%，现在已经成为团队日常工作的重要工具。 + +### 16. 未来你们计划如何进一步优化和扩展这个系统？ + +**回答**：我们有几个重要的优化方向。首先是增强AI Agent的自主学习能力，通过强化学习让Agent能够从历史执行结果中学习，不断优化自己的决策策略；其次是扩展更多的业务场景，比如客服机器人、数据分析助手、项目管理助手等；在技术架构方面，我们计划引入更先进的向量数据库和图数据库，提升知识检索的准确性和效率；在用户体验方面，我们正在开发移动端应用，让用户能够随时随地使用AI Agent服务。同时我们也在探索多模态AI的应用，让Agent能够处理图片、音频、视频等多种类型的数据，进一步扩展应用场景。预计在未来一年内，我们的AI Agent系统将覆盖公司80%以上的业务流程。 + +### 17. 在设计通用对话分析模型时，你们是如何处理问题分析、自主规划、精准执行这个循环的？ + +**回答**：我们设计了一个四阶段的执行循环：问题分析、自主规划、精准执行、内容判罚。在问题分析阶段，AI Agent首先理解用户意图，提取关键信息和上下文；自主规划阶段，Agent根据可用的工具和知识库制定执行计划，选择最优的执行路径；精准执行阶段，按照计划调用相应的MCP工具和Advisor，获取执行结果；内容判罚阶段，Agent评估执行结果是否满足用户需求，如果不满足则重新进入规划阶段。整个过程中，我们为每个阶段配置了不同的Model、MCP、Prompt组合，比如规划阶段使用逻辑推理能力强的模型，执行阶段使用工具调用能力强的模型。这种设计让AI Agent具备了类似人类的思考和执行能力。 + +### 18. 你们的向量数据库检索性能是如何优化的？ + +**回答**：我们从多个层面优化了向量检索性能。在索引层面，PGVector使用了HNSW（Hierarchical Navigable Small World）算法构建高效的向量索引，支持近似最近邻搜索；在查询优化方面，我们实现了查询缓存机制，对于相似的查询直接返回缓存结果；在数据分片方面，我们按照业务领域对向量数据进行分片存储，减少检索范围；在并发控制方面，我们使用了连接池和异步查询，提升并发处理能力。此外，我们还实现了智能的预加载机制，根据用户的历史查询模式预先加载可能需要的向量数据到内存中。通过这些优化，我们的向量检索响应时间从原来的500ms优化到了50ms以内，同时支持千级并发查询。 + +### 19. 在实现MCP服务的过程中，stdio和sse两种模式各有什么优缺点？ + +**回答**：stdio模式的优点是实现简单，适合本地工具调用，通信开销小，调试方便；缺点是只能用于本地服务，不支持远程调用，扩展性有限。sse模式的优点是支持远程调用，可以跨网络部署，支持实时双向通信，扩展性强；缺点是实现复杂度高，需要处理网络异常和重连机制，通信开销相对较大。在实际应用中，我们根据具体场景选择合适的模式：对于文件系统操作、本地命令执行等场景使用stdio模式；对于微信通知、CSDN发帖、远程API调用等场景使用sse模式。为了统一开发体验，我们封装了通用的MCP客户端，屏蔽了底层通信细节，开发者只需要关注业务逻辑即可。 + +### 20. 你们是如何保证AI Agent在复杂业务场景下的稳定性的？ + +**回答**：我们建立了多层次的稳定性保障机制。在架构层面，采用微服务设计，单个服务的故障不会影响整个系统；在服务层面，实现了熔断降级机制，当某个依赖服务不可用时自动切换到备用方案；在数据层面，建立了完善的备份和恢复机制，关键数据都有多副本保护；在监控层面，实现了全链路监控，从请求接入到响应输出的每个环节都有详细的监控指标；在异常处理方面，我们为每种可能的异常场景都设计了对应的处理策略，包括重试、降级、人工介入等。此外，我们还建立了完善的测试体系，包括单元测试、集成测试、压力测试、混沌工程测试等，确保系统在各种极端情况下都能稳定运行。通过这些措施，我们的系统可用性达到了99.9%以上。

+ +
+ +AI Agents 是**系统** ，它通过赋予 **大型语言模型(LLMs)** **访问工具** 和**知识** 来扩展其能力，从而使 **LLMs** 能够**执行操作** 。 + +- **系统** ：将 Agents 视为一个由许多组件组成的系统，而不仅仅是单个组件，这一点很重要。在基本层面上，AI Agent 的组件包括： + - **环境** - AI Agent 运行的定义空间。例如，如果我们有一个旅行预订 AI Agent，则环境可以是 AI Agent 用来完成任务的旅行预订系统。 + - **传感器** - 环境具有信息并提供反馈。AI Agents 使用传感器来收集和解释有关环境当前状态的信息。在旅行预订 Agent 示例中，旅行预订系统可以提供诸如酒店可用性或航班价格之类的信息。 + - **执行器** - 一旦 AI Agent 接收到环境的当前状态，对于当前任务，Agent 会确定要执行的操作以更改环境。对于旅行预订 Agent，它可能是为用户预订可用房间。 +- **大型语言模型** - Agents 的概念在 LLMs 创建之前就已存在。使用 LLMs 构建 AI Agents 的优势在于它们能够解释人类语言和数据。这种能力使 LLMs 能够解释环境信息并制定改变环境的计划。 +- **执行操作** - 在 AI Agent 系统之外，LLMs 仅限于根据用户提示生成内容或信息的情况。在 AI Agent 系统内部，LLMs 可以通过解释用户请求并使用其环境中可用的工具来完成任务。 +- **访问工具** - LLM 可以访问哪些工具由 1) 它运行的环境和 2) AI Agent 的开发者定义。对于我们的旅行 Agent 示例，Agent 的工具受预订系统中可用操作的限制，开发者可以将 Agent 的工具访问权限限制为航班。 +- **知识** - 除了环境提供的信息外，AI Agents 还可以从其他系统、服务、工具甚至其他 Agents 中检索知识。在旅行 Agent 示例中，此知识可以是位于客户数据库中的用户旅行偏好信息。 + +我们可以以一个人，作为视角来理解 AI Agent，Memory 记忆是人的大脑，Tools 是人的身体和四肢，Rag 知识库是过往的经验储备，MCP 是我们与外部的连接调用。而整个人就是这个智能体 AI Agent。 + +## 二、AI 智能体的工作原理 + +每个智能体都定义了角色、个性和沟通风格，包括具体指令和可用工具的说明。 + +
+ +
+ +- **角色**：角色是智能体的核心特征，定义了其性格和行为方式。一个定义良好的角色可以帮助智能体在与环境和用户互动时保持一致性。随着时间的推移，智能体会通过经验积累和环境互动不断发展和完善其角色。 +- **记忆**：智能体的记忆系统由短期记忆、长期记忆、共识记忆和情景记忆组成。短期记忆用于处理即时互动，长期记忆存储历史数据和对话，情景记忆记录过去的互动细节，而共识记忆则用于在智能体之间共享信息。通过这些记忆系统，智能体能够回忆过去的互动，适应新情况，保持上下文一致性，并从经验中学习以提高性能。 +- **工具**：工具是智能体用来与环境互动并增强其功能的资源。它们可以是函数或外部资源，帮助智能体访问信息、处理数据或控制外部系统以执行复杂任务。工具根据其界面类型进行分类，包括物理界面、图形界面和基于程序的界面。通过工具学习，智能体能够理解工具的功能及其应用场景，从而有效地使用这些工具。 +- **模型**：大语言模型 (LLM) 是构建 AI 智能体的基础，赋予智能体理解、推理和行动的能力。LLM 作为智能体的“大脑”，使其能够处理和生成语言，而其他组件则支持智能体的推理和行动能力。 + +> https://github.com/google/A2A 多个 Agent 间，可以使用 A2A 协议，完成 Agent 和 Agent 对接。 + +## 三、AI Agent 场景应用 + +### 1. BCP 智能巡检 + +
+ +
+ +- 场景：在日常的互联网toc场景的系统中，每天都会有不同程度的客诉，这些客诉问题需要进行大量的系统排查。 +- 方案：将企业内的各项系统服务，开发出 MCP 服务接口（APIs），并为每个核心业务流程提供排查链路计划。在发生系统报警时，以报警为触达手段，排查系统日志、账户、Redis、Dev-Ops 服务等，给给出综合的解决方案。 +- 其他：不同配置的 Agent 是可以连接通信的，一个 Agent 就是一个配置出来的 ChatClient 对话体。 + +### 2. 工具AI化设计 + +
+ +
+ +- 场景：其实现在除了编程方面，其他很多软件并没有那么快速的接入 AI Agent。如 trae.ai\cursor 都是编程的利器，可以更快速的迭代开发代码。那么同样的 SSH 链接云服务器的工具，也可以通过 AI Agent 进行扩展，提高我们的操作服务器部署软件的效率。 +- 方案：设计 Linux SSH MCP Server 服务，同时提供 SFTP 以及云服务器的对接。再加上 Linux RAG 知识库。这样我们就可以以对话和编码的方式操作服务器。如，部署 JDK，安装 NodeJS，执行系统镜像的构建、推送、拉取、部署等操作。 + +### 3. toc场景AI化 + +
+ +
+ +- 场景：目前的大部分购物操作，都是人工的方式自己在平台检索，之后对于不懂的在进行客服提问，最后去下单。那么这里也可以加入 AI 操作，自主的完成购物、下单，以及将来退货的操作。 +- 方案：为产品提供购物话术 RAG 增强检索能力，以及提供货物、下单、结算、物流的 MCP 服务。用户和 AI 对话过程中，完成货品的组装选择和下单。聊聊天就把东西买好了，还能给提供产品的使用和维护。 + +### 4. AI Agent 编排 + +
+ +
+ +- 当我们有大量的 MCP 服务实现、RAG 知识库沉淀后，会催生出 AI Agent 的编排能力实现。你可以按需组装一套自己的对话 AI Agent。 +- 类似的场景实现：[https://github.com/n8n-io/n8n](https://github.com/n8n-io/n8n) - 付费的。不过很多企业会借助之前的 BPMN 实现的低代码，扩展出 AI Agent 编排实现。 + +```java +docker volume create n8n_data +docker run -it --rm --name n8n -p 5678:5678 -v n8n_data:/home/node/.n8n registry.cn-hangzhou.aliyuncs.com/xfg-studio/n8n:1.88.0 +``` + diff --git "a/docs/md/project/ai-knowledge/promotion/AI MCP \345\267\262\347\273\217\345\270\256\346\210\221\342\200\234\345\271\262\346\264\273\342\200\235\344\272\206\357\274\201.md" "b/docs/md/project/ai-knowledge/promotion/AI MCP \345\267\262\347\273\217\345\270\256\346\210\221\342\200\234\345\271\262\346\264\273\342\200\235\344\272\206\357\274\201.md" new file mode 100644 index 000000000..88403fbe1 --- /dev/null +++ "b/docs/md/project/ai-knowledge/promotion/AI MCP \345\267\262\347\273\217\345\270\256\346\210\221\342\200\234\345\271\262\346\264\273\342\200\235\344\272\206\357\274\201.md" @@ -0,0 +1,119 @@ +--- +title: AI MCP 已经一天24小时，给我“打工”了！ +lock: no +--- + +# AI MCP 已经一天24小时，给我“打工”了！ + +作者：小傅哥 +

课程：[https://t.zsxq.com/GwNZp](https://t.zsxq.com/GwNZp) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +一天24篇推文，500+收藏，2.6万+阅读量，我已经让 AI 帮我干活了！这是小傅哥最新实现的一套 `mcp-server-csdn`，完全不需要我上手，就可以定时的执行文章编写和发表。 + +
+ +
+ +
+ +
+ +只要你配置好对应的话题，AI MCP 就会自动创作文章和发表。虽然单篇流量不一定都高，但架不住我根本没出手呀，走的就是一个量大取胜！**这不是自动发帖，这是自动创业呀😂！简直美滋滋！** + +
+ +

+ +
+ +
+ +
+ +如图，我们可以给程序设定一套话术描述，让它去做指定类型的文章创作和发表。在 AI 完成内容创作后，会调用 MCP 服务，传递接口入参值，再由 MCP 服务，完成文章的发表。 + +如果，我们希望发布的文章具备当前热点。可以增加一个 MCP 服务，这个服务来检索牛客网最新的求职面试信息，再加上各个大厂招聘要求描述信息等。基于这些信息先获取到面试热点话题，在结合话题与设定的面试场景话术一起生成对应的文章。**MCP 就像是你的员工，你可以交代A员工做什么后，交接给B员工继续处理。** + +## 二、MCP 怎么开发的 + +首先，MCP 是一套标准的模型上下文协议，它不限制非得使用那种语言实现。如；NodeJS、Python、Java，都可以实现 MCP 服务。以 Spring AI 框架举例，Java 工程师可以，以非常简单的使用 Java 代码开发普通的业务逻辑，之后配置上 AI MCP 工具类注解和完成 Bean 对象的实例化即可。 + +
+ +
+ +- 如图，正常的搭建 SpringBoot 应用程序，编写对接 CSDN 发帖接口。之后给服务方法配置上 Tool 工具注解。那么它就会被 Spring AI MCP 注册和使用了。 +- 同时，一个工程里可以有很多的这样的服务和工具。比如你要开发一个各大平台集成的发帖/文章的服务，那么也可以增加其他的对接类在同一个工程里。最终配置上 AI MCP 的注册即可。 + +## 三、MCP 怎么对接的 + +把 Java 开发实现的 MCP 服务端，打包成一个 Jar，把这个 Jar 配置到 MCP 客户端工程里。即可完成 MCP 服务的调用。并且一个 MCP 客户端，也可以对接多套 MCP 服务，这些服务可以以 AI 工作流的形式完成自己的工作。 + +
+ +
+ +
+ +
+ +- 如图，在 SpringBoot 工程中，增加MCP 服务的配置对接。这个时候 AI 对话就那可以拿到 MCP 工具进行对话。并将要执行的信息，通过 MCP 服务工具完成处理。 +- 并且，你可以把 MCP 服务，打包构建镜像部署到（服务器/Nas），让它一天24小时的干活。用不了多久，你就成为某个领域内容的专家了！ + +## 四、MCP 怎么学习下？ + +小傅哥，已经为你准备好了一套 AI RAG、MCP、Function Call 实践编程课程，使用 Java + Spring AI 框架，增强自己的 AI 应用开发能力，迅速囤积编程技能！如下，课程目录，全程文档小册 + 视频带着你从0到1学习。 + +

+ +- 首先，站在用户的使用视角，研发或者运营，可以通过话术描述，完成系列的 AI 工作流，并拿到最终的结果。这就是 MCP 最终为你提供的服务。 +- 那么，你可以想象，在日常的工作中，运营、研发、产品、测试等，都有非常多的重复非创作性的工作，占用了大量的时间成本。尤其是研发，写写代码，就有运营过来，帮我查个问题吧，小嘚嘚。但如果有这样的借助于 MCP 实现的 AI 工作流，就可以完成80%以上的工作量。 +- 之后，站在技术的实现视角，MCP 是一个标准结构框架，你可以按照它（Spring AI）提供的 SDK 开发方式，完成本地化 API 的接入开发。让 AI 有明确的方式调用各类 API 服务接口。如果没有 MCP 这会是一件很麻烦的事情。 + +好啦📢，这就是小傅哥即将为你开启的**《DeepSeek RAG 增强知识库》**第2阶段，`MCP 服务开发和对接`。让你具备 AI 开发能力，遥遥领先于还在扣 CRUD 项目的小伙伴，做面试最牛的仔，最职场最靓的人！ + +> Spring AI MCP 与 24年末发布，学习此 AI 应用开发项目，你将是第一批具备 Java AI 应用实战开发能力的人。竞争力，嘎嘎滴！ + +## 第1期，RAG 我们做了什么 + +在 《DeepSeek RAG 增强知识库》第1阶段，基于 Spring AI 0.8.1 开发了一套可以上传文件和Git仓库进行解析、切割、存储，到使用向量库完成 AI 的知识库问答系统。并最终通过 Docker 部署上线。 + +
+ +
+ +- 基于，RAG 这样的一套知识库，你可以完成文本和代码库的解析。以及自行扩展提供出 RAG 知识库的接口，对接到 OpenAI 代码自动评审（小傅哥社群的另外一个项目），增强代码评审效果。 +- 在这套项目中，可以学习到 Ollama DeepSeek 本地化&云服务部署，以及流式接口的开发、基于 AI 完成页面与知识库对话接口的处理，Linux、Docker 的部署等。小项目不大，但非常锻炼人！ + +## 第2期，MCP 我们要做什么 + +与第2期相比，第1期可以称之为小试牛刀，让小伙伴们以最快、最快的往事，积累，运用 Spring AI 框架，开发自己的 RAG 知识库。~~也是方便有些死鬼，早点写到简历上~~ + +到了第2期，你就开始吃上细糠了，小傅哥会带着你升级 Spring AI 框架为 1.0.0-M6 最新版本，多模型配置和操作 PG 向量库，使用 GPU 搭建响应速度更好的 Ollama DeepSeek 大模型（秒级处理），以及对接官网 DeepSeek 的大模型和统一 one-api 对接方式。 + +但这还只是开始，随着基础框架的升级完成，我们将进入 MCP 服务的开发实现。通过 AI 指令，完成 AI 工作流，调度各项 MCP 处理我们的任务作业。如图，举例操作； + +
+ +
+ +- 基于 MCP 服务的开发和对接，通过 AI 工作流指令，完成数据的采集和存放动作。💡 聪明的小伙伴以及开始联想，基于这样的 AI 开发，可以替代很多的日常工作啦。**没想到吧，也把自己替代了** 但仍然，蠢蠢欲动（我不做，别人也做呀）！~~实现后，晋升又有的讲啦！简历也有东西写啦！~~ +- 有了 MCP 后，相当于把我们需要；在一个网页操作数据库查询数据、打开另外一个网页看天气预报，再手动的创建个文件把以上的信息获取后，复制粘贴到文件里。这一些列操作，都让 AI 通过 MCP 模型上下文协议进行处理。也就是 AI 可以调用后台接口啦！ + +## 课程目录计划 💐 + +此课程会扩展很多基于 Java 的 AI 开发能力学习，帮助大家积累相关的场景解决方案。在这个过程中你可以最快的掌握最新的技术，早早的提前别人一步。 + +

课程：[https://t.zsxq.com/SNsgH](https://t.zsxq.com/SNsgH) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +两年多了，从2023年1月起，小傅哥就开始关注AI、跟进AI，落地 AI 技术相关的场景项目。`做了 AI 问答自动回复助手`、`OpenAI 应用服务（含支付买额度 + OpenAI SDK 开发）`、`OpenAI 代码评审`、`Ai Agent 智能体（RAG、MCP）`，让一众伙伴积累到了丰富的AI应用开发技术，可以满足当下互联网AI应用开发招聘诉求。**那么接下来，关于 AI 小傅哥还要带着大家什么呢？🤔** + +
+ +
+ +**足够高频，互联网AI应用场景，必备项目！** + +现阶段，众多互联网公司把 AI 作为公司的战略目标，基于 AI 为公司各类场景提效。甚至不少公司要求程序员的编码，AI 占比要有30%以上（来自于某论坛研发分享）。还在各个部门设立 AI 应用创新组。 + +而 AI 的主要提效方式，则是自研实现或基于 Dify 搭建一套 AI Agent 智能体。通过智能体把公司的文档资料转换为 RAG 知识库，再通过 MCP 协议对接各类应用的服务接口。这样我们对 AI Agent 智能体下达命令后，就可以进行分析，规划，执行，直至产出最终的结果。更多关于智能体的实现介绍，可以参考[《AI Agent 智能体设计实现》](https://mp.weixin.qq.com/s/dwsfadYKs7Uy4YvHfLFsVQ) + +**死鬼，重点来啦！** + +公司里为了扩展智能体可提效的场景，就要把现有的公司的各类应用服务接口，`日志的`、`监控的`、`服务的`、`交易的`、`结算的`、`营销的`、`人群的`、`数据的`等等，都要转换为 AI Agent 智能体可识别的 MCP 服务接口。这样就可能有成百上千，成千上完，甚至几十万个接口要做实现。 + +那肯定不能每个接口都写一遍 MCP 服务！所以，对于这样的场景问题，公司里会做一套统一的 MCP Gateway 网关服务系统，其他个各类接口（http、rpc），都可以通过一键配置的方式转换为 MCP 协议类型的接口，被 AI 可以识别和使用。 + +
+ +
+ +而小傅哥这次带着你做的 AI 类项目，就是实现一套这样的 **MCP GateWay 网关服务系统**。小傅哥，会带着你，实现MCP服务，分析 MCP 协议，通过做AI服务代理、网页协议对接、JSON-RPC2标准等方式，把 MCP 协议厘清，之后在手把手的带着你编写响应式的 MCP Gateway 网关能力（鉴权也可以放到网关做）。 + +> 🧧 文末提供了，小傅哥所有编程实战项目获取方式，一次加入即可获得17个已完结的和本次新开展的。 + +## 一、能学到啥 + +该项目是 AI 应用场景下的通用技术服务组件类项目，以解决接口 MCP 协议转换而设计实现。在整个项目中，你可以积累到关于 MCP 协议的深度分析，学习分析协议的技巧和方案，并积累关于设计一个组件解决通用场景问题的能力。 + +- 【前端】基于 html、js、div、css，设计 MCP 协议分析页面。 +- 【前端】基于 html、js、div、css，构建一套服务端管理系统，便于 MCP 协议的录入和使用。 +- 【后端】MCP 协议的分析、理解、运用。掌握 MCP 开发和使用的能力。 +- 【后端】基于 MCP 协议的分析和网关设计诉求，构建网关服务库表。 +- 【后端】运用 DDD 分层架构，设计 MCP 网关服务系统。 +- 【后端】构建AI代理服务，断点调试分析 MCP 协议。 +- 【后端】设计 MCP 分析协议网页服务，链接 MCP 服务，观察 MCP 协议。 +- 【后端】基于 Flux 响应式接口，设计实现 MCP 协议的 sse 连接、initialize 初始化响应、tools 工具的 list 反馈和 call 调用等。 +- 【后端】提供 MCP 协议的动态录入和加载能力，以及提供录入接口组件，便于其他系统可快速录入。 +- 【后端】设计 MCP 网关协议鉴权服务，确保 MCP 服务使用的安全性。 +- 【后端】熟练使用 okhttp3、retrofit2 框架，动态对接 HTTP 服务接口，用于 MCP 协议 toos/call 工具调用。 +- 【后端】扩展学习 rpc 泛化调用，给 MCP 协议提供使用。其实有了这套东西，还可以对接如硬件设备 rs232 串口通信，让 MCP 服务，管理你的硬件设备。 +- 【运维】熟练使用 Docker 在本地和服务端的配置和部署应用，以及在本地构建前后端镜像。 +- 【运维】熟练掌握 Git、GitCode，对工程代码的管理，推送、拉取、切换分支、合并代码等操作。 + +此外，小傅哥对于每个章节还讲解了章节的诉求、流程的设计，之后再到方案实现和功能验证。并在每个章节留有作业让大家练习。当然这还没有完，你知道小傅哥这个架构师画图还是非常牛逼的，所以你还能看到各种画图的技巧，耳濡目染的把这些东西学习成自己的本事！~ + +## 二、项目介绍 + +本项目是 AI Agent 智能体，关于 MCP 协议对接的通用网关服务项目，以解决各类业务接口便捷转换为 MCP 协议而设计实现。通过这样的配置，可以大大的简化从普通http、rpc接口到 MCP 协议的转换操作。这样的项目，也是每个互联网公司在做 AI Agent 智能体时，必备的基础设施项目。 + +### 1. 更新计划 + +本项目目前已经做了基础的筹备和验证，计划于10.26日开始更新课程。整体课程预计在20+节左右。带着你完整的实现一套 AI MCP Gateway 网关服务项目。 + +### 2. 项目资料 + +#### 2.1 协议分析 - 页面 + +

+ +
+ +**不了解呀，那怎么办！** + +所以，除了做 AI Agent 智能体，小傅哥还带着你深入核心技术的设计与实现，手把手带着你搓一套 AI MCP 网关（各个大厂都在做的东西）。有这样一套东西，再配合 AI Agent 智能体，就把技术深度给拉起来了。`最后写简历效果咋样？` 有伙伴反馈，如下； + +
+ +
+ +企业里为啥看重这个？ + +现在虽然是 AI 时代，AI 编码，但能驾驭 AI 的人主要是程序员，能更强的驾驭 AI 编码的，肯定编程经验丰富的。所以，你如果能在核心复杂场景里，提供出对应的技术解决方案，那么肯定是会受到企业招聘青睐的。（没有这方面经验，AI 写出来，你都不敢真的对外上线用起来）。 + +那么，为啥是 AI MCP 网关，在企业里那么重要呢？ + +当下互联网toc的业务场景，你会看到你用的购物（天猫、京东）、出行（滴滴）、外卖（美团、饿了吗），都有 AI 场景，这些场景辅助用户完成购物、出行、点餐，极大的增加体验。但本质来说，是 AI 对接了业务系统。怎么对接的呢，方式就是通过 MCP 协议对接，把业务项目的接口（http、rpc）转换为可被 AI 识别的接口，以此方式完成对接。但如果全部手动编码实现，是非常麻烦的。所以 AI MCP Gateway 统一解决这样一个场景问题，是非常有价值的。 + +

视频：[https://t.zsxq.com/i8tV1](https://t.zsxq.com/i8tV1) + +>大家好，我是技术UP主小傅哥。 + +今天是我们 **《AI MCP Gateway 网关服务系统》** 项目学习的第1节课程，小傅哥会带着大家，以互联网公司正规的承接产品需求到开发部署上线的流程，带着大家以第一主人公视角的方式进行学习。这样既可以保证你学习到项目内容，也能了解到公司里正规的开发模式，以后进入到公司也可以很好的融入团队，承接项目需求。加油💪🏻！让我们开启新项目之旅！ + +## 一、本章诉求 + +站在产品视角，分析 AI MCP Gateway 网关服务系统，这样一个产品功能需求的背景、诉求和目的。 + +需求是怎么来的呢？ + +作为互联网公司里的研发，我们通常都是从业务产品经理那承接需求，评审 PRD 文档，之后研发进行详细设计，给出设计文档在评审，评审通过后开始进入编码开发，以及推进后续的测试和上线。 + +那么，还有一类需求是不需要业务产品经理的，往往是纯技术产品经理或者研发和技术一起驱动的，这类的需求包括，系统的重构、组件的设计、框架的升级等。他们虽然也是需求，但不直接影响到产品经理的业务需求，所以往往由技术产品或者研发推动。 + +所以，像是 AI MCP Gateway 网关服务系统，是附属于 AI 应用开发部门的项目，一般是由 AI 技术产品经理推动，这类产品经理，往往比纯业务产品经理要多一些技术储备的。虽然他们编码不熟练，但对技术是有不错的储备，可以很好的规划和推进技术产品。 + +## 二、项目背景 + +MCP 协议的定义和发布，改变了我们使用 AI 的形态。 + +LLM 大模型第一次以 chatgpt 问世时，就足以震撼到我们。它具备各行各业的知识储备，可以识别人类语言，可以完成逻辑关系推理。在很长一段时间里，我们都是把问题抛给大模型，大模型回答后，我们在根据它的回复，复制粘贴到具体的场景进行处理。 + +但大模型不能无中生有，不能根据你的提问，直接帮你完成最终的处理。如；帮我查询最近一天内数据库账户表写入的数据量，这是做不到的，因为大模型并不能直接连接到我们的数据库或者其他任何服务。 + +在 2023 年前，如果想让大模型和程序代码互动，我们经常做的方式是写提示词，告诉大模型我的程序具备什么样的能力，有什么样的接口格式，你需要分析我的问题，并按照最终的执行给出结构化参数。json 格式为 `{"function":"query_user_account","arguments":{"sc":"渠道值"}}` 之后再根据大模型的结果调用对应的程序方法。不过以上方式执行起来的误差较大，经常是需要慢慢微调提示词。 + +到了 2023年6月，OpenAI 发布 gpt-3.5-turbo-0613 模型，给 API 的调用提供了 Function Calling 的能力，只需要在请求 API 的时候传入 functions 参数，告知大模型本地有哪些函数方法可以被调用使用即可。到了 2023年11月，gpt-3.5-turbo-1106 发布，这回开始支持 tools 函数，我们可以在提问的时候，进行网络检索，天气对接。但是这些功能代码， 都被嵌入到大模型调用中，编写起来耦合在一块，维护起来很麻烦。 + +直至到2024年11月，Anthropic 发布了 MCP 协议，将 tools 的封装单独抽离到独立的服务，这种服务称之为 MCP 服务，然后通过远程协议的模式提供给大模型调用。而 MCP 协议的主要作用是将服务转换为可以被大模型识别的格式结构（后面章节会细分析 MCP 协议）。 + +**MCP 为何重要？** + +- MCP 在构建或与 AI 应用程序或代理集成时减少了开发时间和复杂性。 +- MCP 提供对数据源、工具和应用程序生态系统的访问，这将增强功能并改善最终用户体验。 +- MCP 可产生功能更强大的 AI 应用程序或代理，它们可以在必要时访问您的数据并代表您采取行动。 + +
+ +
+ +自从有了 MCP 协议以后，市面上开始出现各类的 AI Agent 智能体服务，如被大家熟知的 `Dify`、`Corz`、`Trae.ai/Cursor` 等。这些都是通用的智能体服务，可以解决市面上大部分通用场景问题。 + +到这以后，各个公司开启了自己的 AI Agent 智能体实现，对公司里自身业务场景进行提效。如账户服务、交易订单、计息计罚、还款计划等，做成智能客户和AI运营工具，都可以为企业提效。那么这里就有一个问题，这些接口想被大模型识别，就要开发为 MCP 协议服务，只有 MCP 协议才能被大模型识别的协议，公司里的各项服务要想被大模型调用，就要编写为一个个的 MCP Server 服务端，这个工作量是非常大的。 + +
+ +
+ +所以，为了解决需要把大量接口开发成 MCP 协议服务的工作，我们可以设计一个 MCP 网关服务系统。它的核心工作原理在于，设计实现一套 MCP 协议的统一服务入口，管理和使用动态化注册的 HTTP/RPC 服务接口。MCP 协议的接口会被接入 MCP 服务的大模型，进行调用，核心过程包括；`建立sse连接创建会话ID`、`初始化服务`、`获取 tools 工具列表`、`响应工具调用`。这些内容，小傅哥会在后续的协议分析中带着大家学习。 + +综上，当我们有了一套 MCP 网关以后，就可以把我们各项所需的接口，快速🔜转换为 MCP 协议，配置给 AI Agent 智能体系统进行使用啦。这也是我们本次课程的最终目的。 + + diff --git "a/docs/md/project/ai-mcp-gateway/\347\254\2541-2\350\212\202\357\274\232\347\263\273\347\273\237\345\273\272\346\250\241\350\256\276\350\256\241.md" "b/docs/md/project/ai-mcp-gateway/\347\254\2541-2\350\212\202\357\274\232\347\263\273\347\273\237\345\273\272\346\250\241\350\256\276\350\256\241.md" new file mode 100644 index 000000000..2ad3c04f6 --- /dev/null +++ "b/docs/md/project/ai-mcp-gateway/\347\254\2541-2\350\212\202\357\274\232\347\263\273\347\273\237\345\273\272\346\250\241\350\256\276\350\256\241.md" @@ -0,0 +1,24 @@ +--- +title: 【更】第1-2节：系统建模设计 +pay: https://t.zsxq.com/FKXfD +--- + +# 《AI MCP Gateway 网关服务系统》第1-2节：系统建模设计 + +作者：小傅哥 +

+ +
+ +- 以用户对数据库的操作为视角，发生用户类的行为操作时【账户、下单、流水】，则会根据用户ID（userId）进行路由，把数据分配到x库y表中。 +- 路由计算的处理，是以配置了 `@DBRouter`注解的 DAO 方法进行路由切面开始。通过获取用户ID（userId）值进行哈希索引计算。哈希值 & 2从n次幂数量的库表 - 1 得到一个值，在根据这个值计算应该分配到哪个库表上去。比如这个是6，分库分表是2库4表，共计8个，那么6就分配到了1库4+2库2个等于6，也就得到了2库2表。 +- 对于计算得到的分库分表值，存入到 ThreaLocal 中，这个东西的目的是可以在一个线程的调用中，可以随时获取值，而不需要通过方法传递。 +- 最后 Spring 在执行数据库操作前，会获取路由。而路由组件则实现了动态路由，从 ThreadLocal 中获取。此外注意，因为还有分表的操作，比如 table 需要为 table_01 这个动作是由 MyBatis Plugin 插件开发实现的。 + +关于数据库路由组件单独录制了课程，更多细节内容可以学习。[数据库分库分表路由组件](https://bugstack.cn/md/road-map/db-router.html) - 这个小组件足够写个简历项目用。 + +此外 [sharding-jdbc](https://bugstack.cn/md/road-map/sharding-jdbc.html) 也可以做分库分表，但直接使用小伙伴们会错过理解分库分表的核心设计，所以我们这里选择使用星球「码农会锁」里的 DB-Router 进行分库分表。 diff --git "a/docs/md/project/big-market/api/\347\254\25414\350\212\202\357\274\232\346\212\275\345\245\226\346\264\273\345\212\250\350\256\242\345\215\225\346\265\201\347\250\213\350\256\276\350\256\241.md" "b/docs/md/project/big-market/api/\347\254\25414\350\212\202\357\274\232\346\212\275\345\245\226\346\264\273\345\212\250\350\256\242\345\215\225\346\265\201\347\250\213\350\256\276\350\256\241.md" new file mode 100644 index 000000000..bbfa8d339 --- /dev/null +++ "b/docs/md/project/big-market/api/\347\254\25414\350\212\202\357\274\232\346\212\275\345\245\226\346\264\273\345\212\250\350\256\242\345\215\225\346\265\201\347\250\213\350\256\276\350\256\241.md" @@ -0,0 +1,35 @@ +--- +title: 第14节：抽奖活动订单流程设计 +pay: https://t.zsxq.com/18CO46Oux +--- + +# 《大营销平台系统设计实现》 - 营销服务 第14节：抽奖活动订单流程设计 + +作者：小傅哥 +

+ +- 首先，用户抽奖开始，需要领取活动，扣减个人账户额度。生成一个抽奖订单。每个用户都有一个活动账户额度，里面包含了；总可参与次数、月可参与次数、日可参与次数。这样的设计是为了应对复杂的业务需求。那么有这样的表，就不能只是在一个表里扣减额度，因为每天都要扣减额度，但只在一个账户中扣减，日的次数第一天扣减完，第二天相当于回复为原始库存继续扣减。所以这里要生成一个出每日活动账户，当前则在自己的日账户中扣减。而总库存的日，是一种镜像记录，方便查询统计的。 +- 账户，在扣减额度和用户的订单，要在一个事务内完成。但不能和后续的抽奖结果继续做事务，因为抽奖的过程还有很多的操作，而已包括缓存的处理，而他们都不能做事务。所以这部分是分开的。 +- 之后，抽奖策略结果计算完毕后，把奖品ID写入中奖记录表中，同时写一个 task 任务表。任务表是发 MQ 消息的。但在写入完成奖品订单后，则直接发送一个 MQ 消息【发送后更新 task 表状态】，如果发送失败则还有 task 任务表，由 job 任务扫描的方式处理。这样可以尽快的发送 MQ 消息。 +- 最后，接收发送的 MQ 开始发放奖品，本节暂时先不处理奖品的发放。 diff --git "a/docs/md/project/big-market/api/\347\254\25418\350\212\202\357\274\232\351\242\206\345\217\226\346\264\273\345\212\250\346\211\243\345\207\217\350\264\246\346\210\267\351\242\235\345\272\246.md" "b/docs/md/project/big-market/api/\347\254\25418\350\212\202\357\274\232\351\242\206\345\217\226\346\264\273\345\212\250\346\211\243\345\207\217\350\264\246\346\210\267\351\242\235\345\272\246.md" new file mode 100644 index 000000000..fdf28d893 --- /dev/null +++ "b/docs/md/project/big-market/api/\347\254\25418\350\212\202\357\274\232\351\242\206\345\217\226\346\264\273\345\212\250\346\211\243\345\207\217\350\264\246\346\210\267\351\242\235\345\272\246.md" @@ -0,0 +1,36 @@ +--- +title: 第18节：领取活动扣减账户额度 +pay: https://t.zsxq.com/198oqnRQL +--- + +# 《大营销平台系统设计实现》 - 营销服务 第18节：领取活动扣减账户额度 + +作者：小傅哥 +

课程：[https://t.zsxq.com/14gswKIeX](https://t.zsxq.com/14gswKIeX) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主小傅哥。 + +👨🏻‍💻 经过5.1假期的一顿框框输出，终于完成了[《大营销项目》](https://bugstack.cn/md/project/big-market/big-market.html)第二阶段的开发和上线，体验地址：[https://gaga.plus](https://gaga.plus) 有了这个项目的落地，也终于可以给大家完整的梳理出一套 DDD 落地指引规范。包括；战略、战术、战役，各个阶段都要做什么，`怎么做风暴模型和四色建模`。有了这套东西参考，小白也能目标明确的做 DDD 项目开发啦！ + +
+ +
+ +**我一直讲，要先实践，再理论！** + +编程，偏理科的东西要先上手实践，再做理论理解。因为所有的理论提出，也都是建立有了实践结果后，抽象出来的理论。但你上来就要用理论去反推结果，并不是一件容易的事情。就像不少的 DDD 文章，往往会用一个理论，去讲另外一个理论，这也导致很多没有实践过的小白伙伴，压根不知道讲的是什么。最终觉得 DDD 太难！ + +所以在近2年的时间里，小傅哥分享了非常多的 DDD 实践内容，包括；DDD 工程结构&脚手架、各项分布式技术栈在 DDD 结构下的使用、DDD 实战项目&小场景训练。这些内容都可以在 [bugstack.cn](https://bugstack.cn) 学习。 + +接下来，小傅哥会带着你走一遍`研发设计评审`，讲解 DDD 落地项目的全部过程。 + +>文末有对应本项目的 DDD 工程代码地址，理论 + 代码 + 视频，学的嘎嘎透彻！ + +## 一、战略、战术、战役 + +首先 DDD 是一种软件设计方法，[Domain-driven design (DDD) is a major software design approach.](https://en.wikipedia.org/wiki/Domain-driven_design) 来自维基百科。软件设计方法涵盖了；范式、模型、框架、方法论，主要活动包括建模、测试、工程、开发、部署、维护。来自维基百科的[软件设计](https://en.wikipedia.org/wiki/Software_design)涵盖信息介绍。 + +在 DDD 领域驱动设计中，常提到`战略`、`战术`，和一少部分会讲到`战役`。这3个词主要讲的是不同的开发阶段所需要完成的事项； + +- 战略 - 建模；领域划分、界限上下文、核心领域 +- 战术 - 架构；工程结构、领域对象、领域服务、领域事件 +- 战役 - 编码；设计原则、设计模式 + +DDD 的战略、战术和战役设计相辅相成，战略提供系统的建模作为宏观指导，战术下面有N个战役，两者则关注具体的实现和编码落地。 + +在维基百科中有不少 DDD 非常好的资料，其中一个是关于事件风暴的，讲解了执行战略设计中风暴模型的步骤。 + +
+ +
+ +>有了这基础认知，接下来我们通过《大营销项目》从需求到设计，一步步了解系统的领域驱动设计。 + +## 二、产品需求 + +### 1. 产品诉求 + +如图，是一个复杂的营销抽奖场景玩法需求，涵盖了；`活动配置`、`签到&奖励`、`活动账户`、`抽奖策略「责任链+规则树」`、`库存扣减`、`抽奖满N次后阶梯抽奖`等。面对这样的复杂系统，非常适合使用 DDD 落地。 + +
+ +
+ +分析需求； + +1. 整体概率相加，总和为1或者分值计算，概率范围千分位 +2. 抽奖为免费抽奖次数 + 用户消耗个人积分抽奖 +3. 抽奖活动可给用户分配可抽奖次数，通过点击签到发放 +4. 活动延伸配置用户库存消耗管理，单独提供表配置各类库存 + 用户可用总库存、用户可用日库存 +5. 部分抽奖规则，需要抽奖n次后解锁，才能有机会抽取 +6. 抽奖完成增加（运气值/积分值/抽奖次数）记录，让用户获得奖品。 +7. 奖品对接，自身的积分、内部系统的奖品 +8. 随机积分，发给你积分。 +9. 黑名单用户抽奖，则给予固定的奖品。 + +### 2. 业务流程 + +依照于产品需求，在产品的 PRD 文档中还会绘制出业务流程图。产品的流程图会比较粗一些，研发后期需要根据产品的 PRD 文档做具体的设计。 + +
+ +
+ +- 产品经理会详细的介绍整个系统的功能流程和需要对接接口文档。 +- 以上就是以用户旅程为维度，从点击签到获得活动账户额度，再到一些列抽奖、抽奖策略、中奖结果和奖品发放的流程。 + +## 三、系统架构 + +如果首次承接的是一个新的系统，还需要对系统进行架构设计，是单体架构还是分布式架构，以及所要用到的技术栈。最好在提供好相关的落地案例和DDD脚手架。—— 没有这些东西，就想说点理论，就让团队用DDD写代码，那就是天方夜谭！*你都没写出DDD代码，兄弟👬🏻哪里去复制！* + +**资料**：—— 详细介绍了 DDD 落地的案例和通用的脚手架。 +- DDD 架构：[https://bugstack.cn/md/road-map/ddd.html](https://bugstack.cn/md/road-map/ddd.html) +- MVC2DDD：[https://bugstack.cn/md/road-map/mvc2ddd.html](https://bugstack.cn/md/road-map/mvc2ddd.html) +- DDD 脚手架：[https://bugstack.cn/md/road-map/ddd-archetype-maven.html](https://bugstack.cn/md/road-map/ddd-archetype-maven.html) + +### 1. 分布式架构 + +
+ +
+ +### 2. 分布式技术 + +
+ +
+ +## 四、战略设计 + +不少伙伴，都讲过不知道怎么开始 DDD，主要是拿到一个需求，不知道从哪下手，也不知道那些领域的模型是怎么弄出来的。好，这次小傅哥就给你整个完整的案例，告诉你如何开始。 + +### 1. 用例图 + +根据业务需求画系统用例图； + +
+ +
+ +- 用例图（英语：use case diagram）是用户与系统交互的最简表示形式，展现了用户和与他相关的用例之间的关系。通过用例图，人们可以获知系统不同种类的用户和用例。用例图也经常和其他图表配合使用。 +- 用例图，也可以等同于是用户故事（英语：User story）（软件开发和项目管理中的常用术语），主旨是以日常语言或商务用语撰写句子，是一段简单的功能表述。以客户或使用者的观点撰写下有价值的功能、引导、框架来与使用者进行互动，进而推动工作进程。可以被认为是一种规格文件，但更精确而言，它代表客户的需求与方向。以该用户故事来反应对象在组织内的其工作职责、范围、需要进行的任务等。用户故事在敏捷开发方法中用来定义系统需要提供的功能和实现需求管理。 +- 尽管用例本身会涉及大量细节和各种可能性，用例图却能提纲挈领地让人了解系统概况。它为“系统做什么”提供了简化了的图形表示，因此被誉为“搭建系统的蓝图”。 + +### 2. 事件风暴定义 + +在使用 DDD 的标准对系统建模前，一堆人要先了解 DDD 的操作手段，这样才能让产品、研发、测试、运营等了解业务的伙伴，都能在同一个语言下完成系统建模。 + +
+ +
+ +- 蓝色 - 决策命令，是用户发起的行为动作，如；开始签到、开始抽奖、查看额度等。 +- 黄色 - 领域事件，过去时态描述。如；签到完成、抽奖完成、奖品发放完成。它所阐述的都是这个领域要完成的终态。 +- 粉色 - 外部系统，如你的系统需要调用外部的接口完成流程。 +- 红色 - 业务流程，用于串联决策命令到领域事件，所实现的业务流程。一些简单的场景则直接有决策命令到领域事件就可以了。 +- 绿色 - 只读模型，做一些读取数据的动作，没有写库的操作。 +- 棕色 - 领域对象，每个决策命令的发起，都是含有一个对应的领域对象。 + +**👩🏻‍🏫敲黑板** 综上，左下角的示意图。就是一个用户，通过一个策略命令，使用领域对象，通过业务流程，完成2个领域事件，调用1次外部接口个过程。我们在整个 DDD 建模过程中，就是在寻找这些节点。 + +### 3. 寻找领域事件 + +接下来，大量的时间，都是在挖掘领域事件。这个过程就是一堆人头脑风暴的过程，避免错失流程节点。 + +
+ +
+ +- 根据产品 PRD 文档，一起开会梳理有哪些领域事件。其实大多数领域事件一个人都可以想到，只是有些部分小的场景和将来可能产生的事件不一定覆盖全。所以要通过产品、测试、以及团队的架构师，一起讨论。 +- 像是整个大营销的抽奖会包括如图所列举的事件。在列举这个阶段，你用在乎格式。也可以是每个人准备好黄色便签纸，想到一个就贴到黑板上一个，只是穷举完成。—— 实际做DDD中，也是这样用便签纸贴黑板，所以用不同的颜色做区分。 + +### 4. 识别领域角色和对象 + +在确定了领域事件以后，接下来要做的就是通过决策命令串联领域事件，并填充上所需要的领域对象。这块的操作，新手可以分开处理，如先给领域事件添加决策命令、执行用户和领域对象，最后在串联流程。就像 `事件风暴定义` 中的示意一样。 + +
+ +
+ +- 首先，通过用户的行为动作，也就是决策命令，串联到对应的领域事件上。并对复杂的流程提供出红色的业务流程。 +- 之后，为决策命令添加领域对象，每一个领域在整个流程中都起到了至关重要的作用。 + +### 5. 划分领域边界 + +有了识别出来的领域角色的流程，就可以非常容易的划分出领域边界了。先在事件风暴图上圈出领域边界，之后在单独提供领域划分。 + +#### 5.1 圈出领域 + +
+ +
+ +#### 5.2 领域边界 + +
+ +
+ +- 到这步咱们就可以获得整个项目中 DDD 的领域边界划分了。之后再往下就是具体的每个领域对象的详细设计和流程设计。 + +### 6. 研发详细设计 + +#### 6.1 实体对象 + +
+ +
+ +- 你需要对每一个领域对象进行字段的详细设计。并划分出它们的上下文关系。一般在公司中，这部分设计完成，其他人也能对照你的设计进行代码开发。 + +#### 6.2 流程设计 + +
+ +
+ +- 流程设计，就是更详细的设计了。每一步要调用到哪个系统，哪个接口，要执行什么动作就全部都有了。 + +## 五、工程实现 + +DDD 的战略设计做完，划分出领域边界以后。接下来就是要执行战术和战役了。也就是在工程中做编码实现。但一定要懂得设计原则和设计模式，否则写不出好的代码的。 + +
+ +
+ +- 工程实现，就是在确定的框架结构中编码。可以是洋葱架构、整洁架构、菱形架构等等。这部分内容的可以通过实战项目来锻炼，获得编码技巧。 + +## 六、实战项目 + +注意📢，加入小傅哥的【星球：码农会锁】即可获得大营销项目学习，此外还包括：OpenAI 应用、API网关、Lottery抽奖、IM通信、SpringBoot Starter 组件开发、IDEA Plugin 插件开发等，并还有开源项目学习。 + +提示🔓，加入星球即可解锁全部项目，后续的新项目也可以学习。这些内容非常适合提高编程思维和编码能力。与小demo项目不同，这些内容的积累都是面试中的利器！ + +> [🧧加入](https://t.zsxq.com/14gswKIeX) 这样成体系的全量项目学习，放在一些平台售卖，至少都要上千块。但小傅哥的星球，只需要100多，就可以获得大厂架构师对你手把手教学！[https://gaga.plus](https://gaga.plus) - 项目演示地址。 diff --git a/docs/md/project/big-market/dev-ops/openai_big_market.md b/docs/md/project/big-market/dev-ops/openai_big_market.md new file mode 100644 index 000000000..24d9541ea --- /dev/null +++ b/docs/md/project/big-market/dev-ops/openai_big_market.md @@ -0,0 +1,415 @@ +--- +title: 第4节：课程完结，上线部署教程 +lock: no +--- + +# 《大营销平台系统设计实现》 - 开发运维 第4节：课程完结，上线部署教程 + +作者：小傅哥 +

+ +- 大营销项目到了当前的第2阶段，会把各项分布式技术栈综合运用到项目中。这些技术栈也是各个中大厂中所选择的技术栈。 +- Dubbo 用于内部微服务间的通信，Nacos 作为它的注册中心，起到负载的作用。 +- xxl-job 是分布式任务调度系统，负责任务的分发。 +- Redis 处理缓存数据、延迟队列、分布式锁。【还有库存类无锁化处理】 +- 数据库采用分布式分表设计，之后通过 binlog 使用 canal 同步数据到 Elasticsearch 提供聚合查询。 +- Zookeeper 作为动态配置使用【也可以使用其他的，这里更多的想基于 Zookeeper 把动态更新的原理体现给大家】 +- MQ 消息作为微服务内的信息流转使用。【Kafka、RocketMQ、RabbitMQ 都可以】 +- 最后是服务的负载部署，和熔断限流配置。 + +>综上这些分布式技术栈，在项目中实战锻炼一遍，也就彻底的搞清楚了分布式架构系统的设计原理和实现手段了。 + +## 三、流程设计 + +与一些网上免费demo项目的不同，大营销系统具有非常细腻业务流程。在公司真实做项目怎么做设计，就把这样细腻的流程设计展示给大家。这样读者以后进入公司做项目开发的时候，也能拿出一手漂亮的图稿、细腻的思考。 + +如图是大营销流程前面2个阶段的业务流程执行过程，从这里就能看出整个系统的设计是含带有设计模式的思考的。所以在你看到小傅哥的代码时，也会发现；“源码代码可以写的这么清晰！” 这也是你学习这样一个系统的价值。 + +
+ +
+ +- 面试中最怕的就是项目没得讲，没有一个不错的架构，也没有技术的创新，还没有设计模式对场景的解决。整个项目就像是 CRUD 把数据库的数据展示到页面，就结束了。所以面试中让讲点东西也都讲不出来。 +- 而星球「码农会锁」全部项目，都在为你灌输高级的编码架构技巧和实战设计方案。让你学习后不仅是面试，也能在工作中拿出漂亮的设计，让领导刮目相看。（这可都是一年年评价晋升、涨薪的技巧） + +> 👏🏻欢迎加入小傅哥的星球一起学习下，感受感受高质量的编码，也让自己那一圈子里腰部以上的人！ + +## 四、启动学习 + +小傅哥是把星球「码农会锁」当成互联网公司中一个事业群，所需要开发的技术项目来进行构建。所以在小傅哥的星球既可以学习业务项目，还可以掌握技术组件项目。同时为了大家更好的补充项目学习中欠缺的技术点。小傅哥还把各项技术栈拆成独立的案例分享给大家。 + +>🧧星球「码农会锁」的知识体量是非常成体系的，也非常全面。加入这样一个星球，你的技术就可以稳步提升了！项目预览地址：https://gaga.plus diff --git a/docs/md/project/big-market/extra/big-market-v3.md b/docs/md/project/big-market/extra/big-market-v3.md new file mode 100644 index 000000000..2ddc2617a --- /dev/null +++ b/docs/md/project/big-market/extra/big-market-v3.md @@ -0,0 +1,159 @@ +--- +title: 第二阶段启动，分布式架构进行70% +lock: no +--- + +# 《大营销平台系统》第二阶段启动，分布式架构进行70% + +作者：小傅哥 +
博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主，小傅哥。 + +我发现，其实不少伙伴并不具有分布式架构开发的经验，而学生👩🏻‍🎓不懂也是在所难免的，但那些`死鬼面试官`管你是不是学生，只要有卷王在，那就拔尖面。还有一部分伙伴一直在公司做 ERP、做B端的，就是业务流程，长、长、长、长、长，但核心技术基本没咋使用。 + +
+ +
+ +**那微服务&分布式架构，都有哪些知识点呢？要怎么学？🤔** + +微服务是把一个庞大的单体应用，拆分为独立的个体应用，每个个体应用通过分布在各个云服务器上进行分布式部署，再通过统一配置中心进行管理分布式应用节点。`这里有人提到 DDD 架构，DDD 是对每个应用软件开发的设计手段。与微服务和分布式，不相关。你可以用其他任何软件设计方法来实现一个独立的应用。` + +那么因为从单体拆分到微服务，在部署成分布式架构，也就需要了如；RPC、MQ、Redis、任务调度、分库分表、配置中心、数据同步等各项技术栈的配合使用。因而也引出了；`接口幂等`、`一致性事务`、`掉单补偿`、`延迟队列`、`延迟双删`、`任务扫描`、`熔断`、`降级`、`限流`、`全链路监控`、`TTL打标`等一些列的知识点。**如图；是小傅哥带着伙伴们基于分布式架构实践的系统。** + +
+ +
+ +那么，接下来小傅哥就基于这样一套系统，给大家介绍分布式架构中一些场景的解决方案。 + +>文末有整套项目的学习路径，涵盖；视频(每节30分钟~60分钟)、小册、代码，学起来嘎嘎有收获！ + +## 一、业务介绍 + +### 1. 场景（字节掘金平台） + +为了方便大家理解这块的业务，我们可以看下字节旗下掘金平台的一款实际使用的抽奖效果。因为目前小傅哥做的这块大营销是非常全面的，完全可以支撑掘金的这套使用的。【皮肤UI随便换，电商、出行、外卖各个场景都能用】 + +
+ +
+ +- 地址：[https://juejin.cn/user/center/lottery](https://juejin.cn/user/center/lottery) + +- 流程：`每次点击签到赠送钻石`、`每天免费抽奖1次`、`200个钻石兑换1次抽奖`、`2000个钻石抽奖10次`、`1次抽奖增加10个幸运值`、`6000幸运值可以抽奖到非钻石的实物奖品`、`部分奖品需要抽奖N次后解锁`。—— 这些都是要在系统设计中考虑的点，看着可能不多，但其实满是流程。这也能看出字节研发的功底👍🏻。 + +### 2. 流程 + +基于业务场景诉求，我们来画一下整体的系统的流程。可能看着不大，但流程非常密集。没有点功底，那代码都得写的稀乱。 + +
+ +
+ +- 首先，以用户发起动作为开始，第1步为运营配置活动装配上线，第2~6步为用户参与抽奖活动动作。 +- 之后，第2~4步，为用户对积分的消耗转换为活动账户。类似于你去抓娃娃那，用钱💰换成了币子，几个币子可以抓一次娃娃。 +- 继续，用户从抽奖开始，就类似于商品下单，要扣减他的活动额度账户，比如今天可以参与1次抓娃娃，那么创建一笔流水记录。这样用户如果中途失败了，还可以用流水记录重新发起抽奖。 +- 往下，就可以进入抽奖策略环节了，也就是抽奖大转盘上体现的抽奖N次解锁、多少积分可以抽奖到哪些范围奖品【其实还有黑名单用户抽奖兜底】，这里还有库存的处理。如果2个人同时抽奖到最后1个库存的奖品，就看谁快了，占用了库存的得到奖品，另外一个只能走兜底奖品。 +- 最后，记录用户的中奖信息，和写一个 task 任务表。推送 MQ 消息的方式处理调用接口发奖和回更发奖记录。 + +>那么整个这样的业务和对应的研发流程设计，中间会有哪些细节的场景问题呢？🤔 接下来分析下。 + +## 二、场景方案 + +### 1. 为什么使用分库分表，做了分库分表数据聚合查询如何处理？ + +首先我们要知道，是前期就做好分库分表方案，还是后期在做系统重构分库分表和数据迁移哪个成本高。显然是后面的成本更高。 + +而互联网中大厂中，分库分表的架构设计都是非常熟练的，因为有成熟方案，所以前期就分库分表了。但，为了解释服务器空间。所以把分库分表的库，用服务器虚拟出来机器安装。这样即不过多的占用服务器资源，也方便后续数据量真的上来了，好拆分。 + +那么这里的分库分表后的数据怎么提供汇总、聚合的查询呢？ + +这里需要用到阿里的 canal 组件，基于 mysql 的 binlog 日志，把自己伪装为一个从数据库，通过 dump 交换完成数据的接收和处理。最终把数据同步到 Elasticsearch 等文件服务中在提供聚合查询。对于需要实时的查询以及数据的处理，还可以用到 Flink 方式进行流式计算。 + +### 2. 抽奖奖品库存如何处理，怎么保证最终一致性？ + +在抽奖秒杀这样的场景下，都需要把库存缓存到 Redis 中进行使用。而不能数据库表加行级锁，否则大量的秒杀进行通过加锁和等待释放，就会夯住数据库链接直至拖垮整个服务。 + +那么使用缓存通过大营销项目中的颗粒度更低的分段锁后，怎么来保证一致性呢。这里需要3个步骤，首先是每次扣减完库存，都会写入到 Redis 延迟队列 / MQ 延迟消息，缓慢更新数据库库存。之后是 Redis 内的预热库存消耗完毕后，发送最终 MQ 消息，更新数据库的剩余库存为 0，最终活动结束后，还有任务补偿，扫描抽奖所产生的的参与记录单，更新最终的库存消耗。这里就可以用订单 MQ 通过 Flink 计算，更新最终库存也是可以的。 + +### 3. 写入中奖记录，发送MQ消息失败如何处理？ + +本身发送MQ是可能存在万分之一或者十万分之的失败的，而数据库操作和MQ操作，本身不能做数据库事务。但又要保证失败后的补偿处理。所以要结合中奖记录在写一条发送MQ的任务记录，任务记录上有一个状态，标记是否发送完成，这样就可以通过任务扫描的方式完成 MQ 的补偿发送。 + +但这里要知道，做完本身的中奖记录和任务记录后写库事务后，要顺序的可以是多线程的方式，完成一次MQ发送，并且更新数据库 Task 记录。这里是为了业务流程最快的推进，如果是更新失败也没关系，还有兜底的任务补偿。【任务补偿的数量并不多，但非常需要这个手段】 + +### 4. 生产者可能多次发送同一个MQ，怎么保证奖品不会超发？ + +这是一个幂等的设计处理，MQ 的消息是必须含带具有唯一标识的业务ID的。比如订单ID、奖品ID、支付单ID、交易单ID、贷款单ID等等。接收MQ的系统，通过唯一ID业务，更新或者写库的时候可以保证幂等性。这样也就不会产生超发的可能。 + +### 5. 抽奖算法如何提供O(1)时间复杂度，提高抽奖效率？ + +在大营销系统中，运营人员配置好抽奖活动后，开始上线对外后，会进行数据的预热数据。这个预热的过程会把活动信息、策略信息、库存信息都存储到 Redis 里进行使用。 + +而抽奖的策略就是记录了一个策略下N个奖品的概率，将概率转换为对应的整数数量，写入到缓存中。那么在抽奖的时候就按照整数数量生成随机数来抽奖。这样用空间换时间的效率是非常高的。 + +### 6. 如何对所有分布式节点的应用，活动信息本地内存更新？ + +通常我们会有诉求在不重启系统的时候，就要动态变更所有分布式应用节点中某个属性的值，如开关、缓存、调试日志开启/关闭、熔断、限流、或者抽奖黑名单以及概率等。这些东西通常不是 Redis 存储，而是应用中具体字段的属性值，这样效率更高。 + +而这个操作需要使用到类似于 Zookeeper 组件的临时节点监听，动态变更字段值。详细：[https://bugstack.cn/md/road-map/zookeeper.html](https://bugstack.cn/md/road-map/zookeeper.html) + +### 7. 应用刚启动完成，外部调用过程中发现操作数据库连接池不足，超时断开，过一会又好了？是什么问题？ + +因为它是刚开始有问题，过一会又好了，所以很有可能是池化的连接数配置的最小值与最大值不是一个，这样应用就会先初始一个最小范围的连接数，随着调用没了在初始化到最大连接数。所以一般我们会把最小连接数和最大连接数配置为一个，避免使用的时候还需要初始化。因为初始化连接也是需要花费时间的。【再有注意配置链接的超时时间，不要太小，也不要太大】 + +### 8. 消费MQ的过程中，如果使用多线程会遇到什么问题？ + +这是一个非常容易产生事故的问题，本身 MQ 消费就是多个应用分别消费，如果有消费失败的，可以抛异常重试。但如果是一个消费 MQ 的应用，里面写了多线程，就可能会出现大量的 MQ 挤压，消费不过来，导致系统瘫痪。而如果你重启，那么这些拉下来的 MQ 消息也就随时丢失了。 + +### 9. 分库分表怎么让任务扫描到指定的库表？ + +分库分表以后，需要扫描每个库表中的任务表，则需要手动设定具体要扫描的库和表。如果分库分表的数量比较多，可以用不同的任务配置扫描不同的库表方式来部署，这样可以提高扫描效率。 + +如果说扫描出来的数据需要更低的延迟性，可以考虑做[低延迟任务调度设计](https://bugstack.cn/md/road-map/zookeeper.html)。 + +> 综上都是微服务&分布式架构设计中会出现的场景问题，这些东西是需要实际编码学习才能更好的理解的。更多的问题汇总：[https://bugstack.cn/md/project/big-market/notes.html](https://bugstack.cn/md/project/big-market/notes.html) + +## 三、架构演示 + +小傅哥对于这样一套微服务分布式架构做了非常多的系统方案细节设计，举例如下方便大家参考。—— 这些方案都有平均40-50分钟的视频，由浅入深，循序渐进的讲解。 + +### 1. 活动参与流程 + +

+ +
+ +**那微服务的对接，你有经验吗？** + +没有🤔？没关系，小傅哥为你实打实的提供两套微服务项目的对接使用，包括；后端对接、前端对接，以及不同方式的接口形式对接方案。在这个过程中让你搞懂，这些微服务的对接思路、方式和落地手段。有了这些经验后续你也可以把这样的微服务，衔接到各种项目了上了。让你的项目成为一个蜘蛛网🕸一样的微服务布局。 + +本篇文章提到的两套微服务分别是；`OpenAI 应用项目`、`大营销系统服务 - 抽奖、积分、兑换、返利`，这两套微服务都是小傅哥在星球「码农会锁」为大家提供的实战项目，本节为大家提供出对接方案和效果。非常提高综合实战能力。 + +> 文末有加入学习方式，可以获得整套课程的；视频、文档、代码、面试题、简历模板等。 + +## 一、项目简述 + +- **OpenAi 应用项目**：前后端+Dev-Ops，全栈技术实践。以OpenAi场景，运用DDD架构，实现从微信公众号扫码登录，到下单支付对个人账户充值，完成 OpenAi 控制敏感词过滤以及多渠道策略模型的对话消费的全流程。 +- **大营销平台系统**：前后端+Dev-Ops，全栈技术实践。项目将先以最新DDD架构和模式进行重构Lottery项目，扩展用户、账户、积分、兑换、分享模块，以及和 OpenAI 进行微服务整合，RPC/HTTP 通信完成项目综合使用。 + +>项目演示地址：[https://gaga.plus](https://gaga.plus) - 你可以直接在线查看项目的演示运行效果。这些项目都是企业级的设计和实现，远比简单的 CRUD 那种 DEMO 项目要牛皮的多！ + +## 二、对接方案 + +OpenAI 应用项目，提供了`支付购买对话额度`的服务。那么我们为了促进用户在 OpenAI 项目上的使用粘性，就可以添加营销模块。让用户在完成`每日签到和支付`后，就可以获得相应的积分，再通过积分兑换抽奖次数完成抽奖。抽奖有机会获得不同级别的`对话额度`赠送。以此完成用户行为旅程循环。 + +
+ +
+ +- OpenAI 前端应用，通过 Nginx 负载，HTTP 方式调用 OpenAI 后端和大营销后端服务。完成前端的UI的业务流程串联。 +- OpenAI 后端应用，在支付完成后，调用大营销的返利接口。大营销可以配置完成某个用户行为动作后对应给到积分或者抽奖次数。这个对接可以是 HTTP 或者 RPC 对接。 +- 大营销平台系统，在抽奖的时候增加 OpenAI 额度奖品。也就是抽奖后可以给一个n次数的对话额度，所以大营销需要对接到 OpenAI 提供的 HTTP 接口，处理额度奖品发放操作。 + +## 三、对接效果 + +OpenAI + 大营销，这是一套综合`前后端 + DevOps`的全体系技术实战项目。采用 DDD 架构设计落地，运用设计模式编写整洁的代码实现。结合 OpenAi 技术、微信支付渠道、敏感词过滤、营销积分、兑换、返利的综合玩法项目。 + +### 1. 营销页 + +

核心技术：SpringBoot、MyBatis、MySQL、Redis、SpringCloud/Dubbo【按需添加，只是对外的接口形式】、React、TypeScript +- 项目描述：Raffle 抽奖模块是整个大营销平台系统中非常重要的一个模块，也是本次项目中我来负责的设计和实现的模块。此模块主要以支撑各类差异化抽奖流程，如；通用抽奖、黑名单、人群、N消耗积分指定抽奖范围、抽奖N次解锁奖品等各类玩法的支持。在此系统模块的设计中运用到了模板模式、责任链模式、组合模式、工厂模式，解决代码的可扩展性，并对抽奖的计算和秒杀做了设计的优化，可以支撑单机 4c16g 服务器 500 ~ 800 TPS 的吞吐量（**参考值，以实际压测为准**），抽奖接口响应时长`45毫秒~100毫秒`左右。「不同服务器，带宽，以及是否还配置有环境相关，会有不同的数据效果」 +- 核心职责： + - 以PRD文档诉求和对功能的评审，设计出抽奖的领域模型功能，以及在抽奖的流程抽象上，分为；抽奖前、抽奖中、抽奖后，的节点上扩展各项行为动作。如抽奖前的人群判断、抽奖中库存扣减、抽奖后兜底奖励等。 + - 依赖于领域模型的定义，设计出抽奖库表。抽象抽奖过程为抽奖策略表、策略明细表、规则配置表、规则树动作表，这样会让抽奖更好扩展。 + - 设计模板模式定义抽奖流程标准，再在模板模式中，调用责任链完成抽奖，对于抽奖中和后的动作使用组合模式的规则树进行动态处理【支持库表配置】。 + - 在项目架构中定义统一标准的 api 由触发器层实现，在触发器层定义监听、任务、http、rpc模块，所有的行为动作，都理解为触发行为。 + - 抽奖也是一种峰值流量高的业务场景，因此在设计奖品库存扣减上，采用了 Redis decr 分段消费和加锁兜底的设计，同时对于消费成功的库存，异步队列方式 + 定时任务更新库存。这样可以不超卖的同时，又减少数据库的压力。 + - 在项目开发中熟练运用了 IntelliJ IDEA、WEbStorm、Docker、MySQL、云服务器、SSH工具，并已将项目完整部署到线上【在校伙伴可以提供线上案例版】。 + - 项目采用分布式架构设计，Dubbo 提供 RPC 接口，Nacos 作为注册中心。多机实例任务由 xxl-job 进行调度管理。分库分表数据通过 canal 同步 binlog 日志到 ElasticSearch 进行聚合查询。 + - 通过 RabbitMQ 解耦系统流程，包括；抽奖发奖流程、异步调账消息、异步行为返利，以及在 Redis 缓存库存消耗完毕后，推送MQ消息更新数据库库存和清空延迟队列。 + +## 三、面试问题 + +小傅哥本身也是一个面试官，面试过实习、校招、社招、架构师，不同的面试诉求会有不同的考察范围。通过这些考察范围的问题让求职者通过案例举证，来阐述自己的能力项。而这些能力项的匹配，则是招聘的要求。这里不得不提到，有些小卡拉米的简历，只言片语的项目描述，浮皮潦草的个人职责。是真的没进入面试就没了！ + +接下来是关于大营销平台项目的面试问题解答，可以参考。 + +-

+ +### 1. 你的项目工程是怎么搭建的？ + +项目的搭建类似于使用 start.spring.io 脚手架创建的，在我们的项目中，使用了统一 maven-archetype-plugin 插件，自定义了一套 DDD 工程骨架脚手架。同类项目都是使用这套脚手架创建项目，因为脚手架定义了统一的版本标准和对应配套的开发环境，所以使用起来更加容易。【如果延伸提问，你还了解哪种搭建脚手架的方式，可以回答 [FreeMarker](http://freemarker.foofun.cn/)】 + +### 2. 在你的这个项目中，都用到了什么开发工具？项目是怎么部署的 + +使用到了 IntelliJ IDEA、WebStorm、Sequel Ace/Navicat、ApiPost、Docker、SwitchHosts、Termius（SSH）等，项目上线的时候使用了2个方式，一个是本地构建前后端镜像，PUSH 到 Docker Hub，再通过编写 docker compose 脚本，在云服务器部署。另外一个是搭建 Jenkins 配置部署流水线的方式进行部署。 + +### 3. 整个项目开发过程中，你熟练的掌握了哪些技术栈 + +在整个项目开发中熟练的使用了 SpringBoot、MyBatis、Redisson 等技术框架，在编程功能实现，熟练的结合与 Spring 容器，通过 Map 自动装配 Java 语言实现的策略模式。以及在项目中较多的使用了 Redisson 框架，向 Redis 写入 key-value、queue、map、lock 等数据类型，实现业务功能。 + +### 4. 在项目开发过程中，你有遇到过哪些运行时异常，怎么排查解决的 + +如刚开始项目开发引入脚手架以外的组件，进行调试的时候，因为Jar版本不同。出现过编译通过，调用的时候方法不存在。通过 Maven Helper 插件，检查到有其他组件多引入了相同Jar包。另外还有一些如开发调试中发现的空指针问题，如查后需要增加空对象判断。此外其他一些更多是功能流程实现细节上，如项目中的规则树节点判断流程问题，抛出一些自定义的异常。这些通过在方法上断点调试逐步的解决。 + +### 5. 因为你的项目是前后端分离的，接口跨域怎么做的？ + +首先我们知道，Web跨域（Cross-Origin Resource Sharing，CORS）是一种安全机制，用于限制一个域下的文档或脚本如何与另一个源的资源进行交互。这是一个由浏览器强制执行的安全特性，旨在防止恶意网站读取或修改另一个网站的数据，这种攻击通常被称为“跨站点脚本”（Cross-Site Scripting，XSS）。 + +所以在我的前后端分离项目中，通过配置 @CrossOrigin 注解来解决跨越问题。开发阶段 `Access-Control-Allow-Origin: *`、上线阶段 `Access-Control-Allow-Origin: https://gaga.plus` + +### 6. 看到你的项目用到了 DDD，这也是我们很感兴趣的技术点，你可以介绍下你在使用 DDD 做这个项目时，都运用了 DDD 哪些知识。 + +DDD 是一种软件设计方法，软件设计方法涵盖了范式、模型、框架、方法论等内容，而 DDD 的很多规范约定，都是为了提高工程交付质量。如几个很重要的知识点；框架分层结构、领域、实体、聚合、值对象、依赖倒置等。它所有的手段，都希望以一个功能逻辑的实现为聚合，将功能所需的对象、接口、逻辑，按照领域划分到自己的领域内。 + +就像在这个项目中，我负责实现的抽奖中的策略，就是一个独立的领域模型。在这个领域中我需要提供策略的装载、随机数算法计算、抽奖模板调用（含责任链和规则树）功能，这样一个领域就像划分好的一个独立个体，它拥有属于它的对象信息（实体、值对象、聚合），当需要使用数据库资源、缓存资源，以及外部接口资源的时候，都通过依赖倒置进行调用。也就是说，我的领域不做其他模块的引入，而是领域只负责业务功能实现，所需的所有数据，则有外部接口通过依赖倒置提供。[更多理论知识](https://t.zsxq.com/17tqSU5CE) + +### 7. 你的抽奖流程中，哪些被定义为值对象，哪些被定义为实体对象 + +在 DDD 的规范定义中，值对象通常用于描述对象属性的值，不具备唯一ID，不影响数据变化。如；数据库中字段的枚举值、业务流程中属性对象。如抽奖流程中，RuleLimitTypeVO 规则限定方式的枚举值对象、还有 RuleTreeVO 规则树值对象。而那些实体对象，则具备唯一ID，会影响到最后的写库动作。如；抽奖发起实体、奖品信息实体对象。并且我们可以把一些和实体对象相关的功能聚合到对象内，这样的通用性会更好，避免所有调用方都需要自己编写逻辑。 + +### 8. 关于访问数据层的依赖倒置，是怎么使用的，有什么好处，你可以描述下吗 + +DDD 中的依赖倒置是一个非常好的设计，尤其是与 MVC 结构对比的时候，MVC 的贫血模型结构设计，数据库持久化对象，很容易被当做业务对象使用，这样后期非常难维护。但在 DDD 的分层结构用，是以 domain 领域实现为核心，一个 domain 领域下所需的外部服务，都由领域层定义接口，让基础层做具体实现。而数据库持久化操作，定义的 PO 对象，就被这样的方式被限定在基础层了，外部是没法引入使用的，也就天然的防止了数据库持久化对象进入业务中。 + +### 9. 我看你简历有提到，把抽奖划分为抽奖前、中、后，三个动作。请具体结合场景讲解下，为什么这样设计 + +这个的设计得益于在 Spring/MyBatis 框架源码的学习，在源码中经常会出现对一个流程进行拆分解耦，流程可扩展的点，如 Spring 是 Bean 对象的拆解，MyBatis 是会话流程的拆解。所以在设计大营销的抽奖模块时，对于需求中的各类功能点；黑名单抽奖、权重抽奖、默认抽奖、抽奖N次解锁、兜底抽奖等等情况，是可以拆解为抽奖前、中、后，3个行为动作的，基于这样的考虑后，就可以设计出非常容易扩展的松耦合结构。 + +### 10. 是什么场景下使用了责任链模式，什么场景使用了组合模式，为什么？ + +在设计完抽奖前、中、后，搜耦合的结构模型后，对于抽奖前要执行哪种抽奖，但单向选择问题。所以这里使用了责任链模式，进行节点流程判断，从黑名单、权重，最后到默认，走一个单独的具体抽奖，所以使用责任链更为合适。 + +之后是进入抽奖的中和后，这两部的流程是相对复杂的，需要判断用户抽奖了几次，对于不同次会限定是否能获得某个奖品，同时还有库存的扣减，如果库存不足或者不满足n次抽奖得到某个奖品，则会进行兜底。那么这就是一个树规则的交叉流程，所以会使用了组合模式构建一颗规则树，并通过数据库表的动态配置决定在抽奖前完成后，后续的流程要如何进行。 + +[视频讲解](https://www.bilibili.com/video/BV1f2421M7kc) + +### 11. 抽奖也是一种瞬时峰值很高的业务场景，那么对于抽中奖品后的库存扣减是怎么做的？ + +关于库存的扣减，是一个非常重要的流程。尤其是这种单独资源竞争的场景，如果设计的不好，很容易把服务打挂。 + +所以在这套系统设计中，为了避免库存扣减直接更新库表的行级锁，而导致大量的用户进行等待状态。所以把数据库表的库存同步到 Redis 缓存中，在通过 decr 扣减（incr 的话就和总量比）的方式进行消费，同时为了确保在临界状态、库存恢复、异常处理等情况下不超卖，而对每一条产生从 incr 值，与抽奖的策略ID组合一个key，进行 setnx 加锁兜底，来保证不超卖。—— 这样的设计是颗粒度更小的锁方案设计，性能接近于无锁化。 + +### 12. 你讲到库存的扣减是通过 Redis 滑块锁实现的👍🏻，那么最终同步库是怎么做的，怎么降低对数据库的压力的？ + +关于 redis 缓存和数据库表库存数据的流程，设计了异步更新，保持最终一致性的设计。在执行完库存的扣减操作后（在抽奖中规则树库存节点流程），发送一个扣减完成到 Redis 的异步队列（可以使用MQ+延迟消费），之后通过定时 Schedule Job 来消费队列。这样就可以控制效率速率，降低对数据库的压力。（因为我们不能 Redis 扣减的多快，就直接打到库表上，那样对数据库的压力依然很大，容易打挂） + +### 13. 你提到了接口的单一职责设计，这部分具体讲解下。 + +单一职责原则的核心思想是，一个类应该只有一个引起它变化的原因。也就是说一个类应该只负责一项任务或功能，如果一个类承担了过多的职责，那么这个类就会变得复杂，难以维护和扩展。 + +这样的原则在一些需要长期使用、迭代、维护的功能设计上，是非常重要的。我们要尽可能的让大营销的抽奖领域领域模块具备独立性，所以要使用单一职责原则。在这个原则约束下，设计了3个接口类；抽奖策略接口、奖品信息接口、库存处理接口（异步扣减等），这样3个接口的设计，在将来需要扩展的时候，会非常容易。（可能会问具体编码，问的比较多样性，这部分需要自己阅读代码来学习） + +### 14. 在项目中你提到了可以支持不同场景的抽奖诉求，比如；多少积分后可以抽奖一个固定范围的奖品，或者抽奖n次后，才可以中奖某个奖品。这部分你是怎么做的？库表怎么设计的？ + +这块的流程，就是前面关于大营销抽奖领域模型的设计，从而确定的库表设计。也就是常说的领域->驱动设计。 + +库表包括；策略表、策略明细（库存、概率、规则key）、奖品表、规则表、规则树（3个表）—— 这部分在学习项目后，需要具备能在纸上画出库表ER图。 + +### 15. 你的抽奖接口响应时间是多少？ + +这样的问题主要考察你是否做了项目的上线，以及了解过接口的响应时间。如果做过就非常好回答，没做过乱说是挺容易被继续提问的。 + +参考数据；2c2g 云服务器，部署项目（含mysql、redis），占用63%内存，抽奖接口响应时间为38~55毫秒（项目有完整的手把手部署教程，还有监控部署教程，可以自己部署验证）。 + +### 16.（开放问题）你在做项目中，什么问题难住你的时间最长，为什么？ + +这是一个开放问题，重点考察你对项目的开发中个人的积累。你可以针对自己的学习过程中，有哪个流程的实现，让你最为有感触，即可回答。 + +如；可以对大营销抽奖模型流程的设计和库表设计，最为耗时，因为你不断的在思考如何拆解出一个好扩展的松耦合结构，同时拆解后，还要保证搜耦合下的高内聚。所以这部分是比较耗时的。同时也可以说在设定某个方法的，名称、入参、出参时，做了大量的思考。因为名字的定义非常影响以后的理解。好的代码就是文档，所以对于这样的东西花费不少时间。 + +### 17. 为什么使用分库分表，做了分库分表数据聚合查询如何处理？ + +首先我们要知道，是前期就做好分库分表方案，还是后期在做系统重构分库分表和数据迁移哪个成本高。显然是后面的成本更高。 + +而互联网中大厂中，分库分表的架构设计都是非常熟练的，因为有成熟方案，所以前期就分库分表了。但，为了节省服务器空间。所以把分库分表的库，用服务器虚拟出来机器安装。这样即不过多的占用服务器资源，也方便后续数据量真的上来了，好拆分。 + +那么这里的分库分表后的数据怎么提供汇总、聚合的查询呢？ + +这里需要用到阿里的 canal 组件，基于 mysql 的 binlog 日志，把自己伪装为一个从数据库，通过 dump 交换完成数据的接收和处理。最终把数据同步到 Elasticsearch 等文件服务中在提供聚合查询。对于需要实时的查询以及数据的处理，还可以用到 Flink 方式进行流式计算。 + +### 18. 抽奖奖品库存如何处理，怎么保证最终一致性？ + +在抽奖秒杀这样的场景下，都需要把库存缓存到 Redis 中进行使用。而不能数据库表加行级锁，否则大量的秒杀进行通过加锁和等待释放，就会夯住数据库链接直至拖垮整个服务。 + +那么使用缓存通过大营销项目中的颗粒度更低的分段锁后，怎么来保证一致性呢。这里需要3个步骤，首先是每次扣减完库存，都会写入到 Redis 延迟队列 / MQ 延迟消息，缓慢更新数据库库存。之后是 Redis 内的预热库存消耗完毕后，发送最终 MQ 消息，更新数据库的剩余库存为 0，最终活动结束后，还有任务补偿，扫描抽奖所产生的的参与记录单，更新最终的库存消耗。这里就可以用订单 MQ 通过 Flink 计算，更新最终库存也是可以的。 + +### 18. 写入中奖记录，发送MQ消息失败如何处理？ + +本身发送MQ是可能存在万分之一或者十万分之的失败的，而数据库操作和MQ操作，本身不能做数据库事务。但又要保证失败后的补偿处理。所以要结合中奖记录在写一条发送MQ的任务记录，任务记录上有一个状态，标记是否发送完成，这样就可以通过任务扫描的方式完成 MQ 的补偿发送。 + +但这里要知道，做完本身的中奖记录和任务记录后写库事务后，要顺序的可以是多线程的方式，完成一次MQ发送，并且更新数据库 Task 记录。这里是为了业务流程最快的推进，如果是更新失败也没关系，还有兜底的任务补偿。【任务补偿的数量并不多，但非常需要这个手段】 + +### 19. 生产者可能多次发送同一个MQ，怎么保证奖品不会超发？ + +这是一个幂等的设计处理，MQ 的消息是必须含带具有唯一标识的业务ID的。比如订单ID、奖品ID、支付单ID、交易单ID、贷款单ID等等。接收MQ的系统，通过唯一ID业务，更新或者写库的时候可以保证幂等性。这样也就不会产生超发的可能。 + +### 20. 抽奖算法如何提供O(1)时间复杂度，提高抽奖效率？ + +在大营销系统中，运营人员配置好抽奖活动后，开始上线对外后，会进行数据的预热数据。这个预热的过程会把活动信息、策略信息、库存信息都存储到 Redis 里进行使用。 + +而抽奖的策略就是记录了一个策略下N个奖品的概率，将概率转换为对应的整数数量，写入到缓存中。那么在抽奖的时候就按照整数数量生成随机数来抽奖。这样用空间换时间的效率是非常高的。 + +### 21. 如何对所有分布式节点的应用，活动信息本地内存更新？ + +通常我们会有诉求在不重启系统的时候，就要动态变更所有分布式应用节点中某个属性的值，如开关、缓存、调试日志开启/关闭、熔断、限流、或者抽奖黑名单以及概率等。这些东西通常不是 Redis 存储，而是应用中具体字段的属性值，这样效率更高。 + +而这个操作需要使用到类似于 Zookeeper 组件的临时节点监听，动态变更字段值。详细：[https://bugstack.cn/md/road-map/zookeeper.html](https://bugstack.cn/md/road-map/zookeeper.html) + +### 22. 应用刚启动完成，外部调用过程中发现操作数据库连接池不足，超时断开，过一会又好了？是什么问题？ + +因为它是刚开始有问题，过一会又好了，所以很有可能是池化的连接数配置的最小值与最大值不是一个，这样应用就会先初始一个最小范围的连接数，随着调用没了在初始化到最大连接数。所以一般我们会把最小连接数和最大连接数配置为一个，避免使用的时候还需要初始化。因为初始化连接也是需要花费时间的。【再有注意配置链接的超时时间，不要太小，也不要太大】 + +### 23. 消费MQ的过程中，如果使用多线程会遇到什么问题？ + +这是一个非常容易产生事故的问题，本身 MQ 消费就是多个应用分别消费，如果有消费失败的，可以抛异常重试。但如果是一个消费 MQ 的应用，里面写了多线程，就可能会出现大量的 MQ 挤压，消费不过来，导致系统瘫痪。而如果你重启，那么这些拉下来的 MQ 消息也就随时丢失了。 + +### 24. 分库分表怎么让任务扫描到指定的库表？ + +分库分表以后，需要扫描每个库表中的任务表，则需要手动设定具体要扫描的库和表。如果分库分表的数量比较多，可以用不同的任务配置扫描不同的库表方式来部署，这样可以提高扫描效率。 + +如果说扫描出来的数据需要更低的延迟性，可以考虑做[低延迟任务调度设计](https://bugstack.cn/md/road-map/zookeeper.html)。 + +> 综上都是微服务&分布式架构设计中会出现的场景问题，这些东西是需要实际编码学习才能更好的理解的。更多的问题汇总：[https://bugstack.cn/md/project/big-market/notes.html](https://bugstack.cn/md/project/big-market/notes.html) + +### 25. 如果在多机部署的情况下，是不是每台机器都会有这个定时任务，如果它们都捞到同一条发送失败的消息，会不会导致消息的重复发送？怎么避免？ + +问题：[https://t.zsxq.com/4uoyl](https://t.zsxq.com/4uoyl) + +1. 幂等的这个是ok的，没问题的。 +2. 一个任务就是要有多机备份，避免一个挂了，就没有人执行了。之后这里的方案是加锁； + - 2.1

我都不知道怎么答 + +量化人群，是量化分析师，通过 Python、R 语言对历史数据进行建模（R语言有数据分析公式）。目的是为了根据一个人的，人标签和行为数据，跑出谁喜欢xxx，谁爱购买xxx，谁有xxx意向。之后创建出人群包。这样系统会根据人群包做抽奖、发券等的差异化。 + +### 27. 有个问题想确认一下 大营销系统和业务系统 是在同一个注册中心里吗，业务系统是直接调用抽奖服务的dubbo接口么 + +一个公司里，rpc 都是一个注册中心。 + +### 28. 关于幂等和流程解耦 + +- Q1: rabbitMQ判断重复消费的逻辑是什么，是直接在数据库中查询返利记录表是否有相同的订单ID(这个订单ID对应着当天日期？)的记录，如果发现重复就不消费？ +- Q2: 感觉“签到返利”这一块也有点像幂等性的实现，即可能会执行多次签到动作，但每天只会执行一次返利操作？ +- Q3: 对于“签到返利”这种行为，用MQ解耦是不是太小题大做了。首先它并不是什么高流量的行为，没必要用MQ来削峰填谷；其次，这样会不会导致执行了 签到 操作之后，用户积分得隔较长一段时间才会更新，出现数据不一致的情况？ + +回答：[https://t.zsxq.com/zbUUb](https://t.zsxq.com/zbUUb) + +### 29. 前几天面试官问我策略领域和奖品领域为什么要划分开 + +1. 这部分要从建模讲，最开似的系统建模是整理出用户用例图，根据用例图梳理四色建模的领域事件。[四色建模过程](https://bugstack.cn/md/project/big-market/ddd.html) +2. 在领域事件脑暴完成，之后就是识别领域角色和对象，这个过程会显而易见的发现有抽奖领域、发奖领域。他们可以作为解耦设计，独立使用。因为抽奖不一定发奖，抽奖可以独立提供算法结果，由外部其他系统使用。发奖也可以除了抽奖的发奖，还有积分兑换的发奖等。如果抽奖和发奖合并，那么外部调用就会不那么清晰。 + +### 30. 根据抽奖问题问了如果把redis中 滑块锁过期时间设置为活动过期时间的时候，如果活动时间很长导致滑块锁过多怎么解决 + +可以考虑给活动库存的锁的key上年月日，每个日的key，明天就重新从新的key开始了。之后这样就比较好较短时间存储了。 [更多讨论](https://t.zsxq.com/vNy0U) + +### 31. 分布式锁使用场景 + +项目中有两个地方使用了分布式锁，分别来处理库存的抢占竞争和分布式任务调度的抢占。 + +1. 库存的抢占设计的是接近于无锁化的库存编号自增后加锁，做兜底设计，这样的用户的抢占就是 incr 后的结果加锁，降低竞争。 +2. 另外一个是项目是分布式架构，有多个任务执行（补偿mq、流转订单状态等），之后如2个任务，一起补偿发mq，避免发送多了，就会做一个抢占设计。谁先拿到可执行key，那么这个任务就执行。这样确保了，一个任务挂了，也可以有另外任务做处理。 + +## 四、公司面试 + +### 【美团】1. 领域模型是怎么设计的，抽奖过程是什么样，DDD四层架构和职责，以及为什么要这么设计？少卖和超卖。 + +问题：[https://t.zsxq.com/180Qz9WCg](https://t.zsxq.com/180Qz9WCg) + +1. 虽然目前大营销是开发了第1个阶段，但在前面讲解中把所有的流程是都介绍了。领域模型官方话术是头脑风暴，罗列事件和行为，在根据实体来划分领域的。简单说也就是根据业务流程划分的。这个过程包括；活动域、抽奖域、积分域、兑换域。也就是用户通过某种行为记录，发放计算，兑换活动参与资格，完成抽奖获得奖品。 +2. 抽奖的流程可以根据目前的设计实现来描述，举例，掘金的这个抽奖就可以用星球的大营销来实现；https://juejin.cn/user/center/lottery?from=lucky_lottery_menu_bar 可以多体验下，体验透彻了，在结合项目的实现，也就能描述出来了。 +3. 关于 DDD 的分层结构介绍，和每层的关系；https://bugstack.cn/md/road-map/mvc2ddd.html +4. 超卖不会出现，有个保证的点，一个是 decr 值的限制，另外一个是对每个key加锁的兜底设计。确保了不会超卖。少卖是有可能的，核心原因是因为 decr 操作和数据操作不是是一个事务，有可能库存扣减完了，但最终操作库失败了。那么这个库存就丢失了，可能会少卖。但一般并不会对少卖做过多的流程，如果想管理，也可以把少卖的库存异常，加入单独的 redis 队列来重新消费就可以了。 + +### 【淘天】2. 对于数据库和redis的一致性怎么解决 + +问题：[https://t.zsxq.com/18ddtmzqW](https://t.zsxq.com/18ddtmzqW) + +- 第1个手段；每次消费 decr 值，写入延迟队列，趋势更新数据库数据。最终一致。 +- 第2个手段；decr 库存值消耗为0时，发送mq消息，更新最终库存量。（可能不准，比如 decr 值消耗中，少卖的情况） +- 第3个手段；活动到期后，任务扫描活动产生订单量，校准库存。 + +### 【其他】3. 什么情况下使用DDD架构，什么情况下使用mvc架构？ + +DDD 是软件设计方法，对复杂的项目更为合适。但这里要清楚，DDD 如果只的是设计方法中的建模工程结构，和 MVC 对比的话。DDD 的结构更为先进，即使不使用 DDD 的软件设计方法，只遵循这套结构，都是可以编写出非常好的代码的。MVC 的约束相对较低，个人开发还好，如果多人协作，会出现腐化严重的问题。 + +### 【其他】4. 设计模式带来了什么好处？举个例子 + +设计模式可以让工程设计的迭代性、扩展性、维护性，都更强，更好。如，抽奖策略计算中，用到了责任链、组合模式的规则树。规则树可以动态的调整配置的节点，来满足各种业务诉求。还可以结合产品需求，迭代的时候添加对应的节点开发就可以。避免了大量if...else的使用，让变动范围缩小到指定的类中。研发成本更低，提测质量更高（测试更快），交付效率更强。这些都是使用设计模式的优势。 + +### 【其他】5. 最近大营销抽奖项目被问到抽奖项目按道理应该不是一个高并发的过程，不是想那种抢优惠券这种属于高并发，那如果抽奖不是高并发，那为啥还要把库存缓存到redis去抗并发呢？ + +要好好留心日常的场景，都是面试的话术； +1. 春晚红包是不是抽奖，拼多多一进页面就有各种【转转转】来获得一个券，支付完成又一个转转转。直接领券远没有抽奖来的刺激，即使是发券，也是用抽奖方式更多。 +2. 每秒的请求量如果超过1000tps，打到库上资源竞争，都会出现大量的数据库连接等待。一般一个应用分配的数据库连接池也就那么20来个。如果都打到库上，都能把库打挂。 +3. 面试这么问，大部分是为了通过一个质疑的场景，来看是否有思考过。而不是面试问什么就是什么，反而是问什么就不是什么，但不是什么，要拿出举证理由。 + +### 【其他】6. 抽奖算法提问 + +1. 问：数据库路由算法 答：hashcode保证两次散列结果一致，扰动函数保证散列均匀。 问：除了hashcode数据库路由算法还有其他的吗？ +2. 问：抽奖除了加分布式锁还有没有别的思路？ 答：这里本质上还是保证库存不超卖，说了低并发下的数据库行锁，redis队列 问：还有其他思路吗？ 答：想不出来了（面试官说依赖高性能的中间态，这块没理解） +3. 计次模型，设计一天一次的参与规则，怎么实现？ +4. 抽奖算法的实现？这个随机怎么可控，怎么避免高价的奖品一开始就被抽掉了，类似于活动中间阶段才能中一次一等奖 +5. 了解过其他抽奖算法吗？ +6. 黑名单如果上到一定规模，比如百万级别，有其他的设计思路吗？ +7. 扣减库存的分段竞态锁用 incr 还是 decr，为什么是 incr/decr？ +8. 如果活动开始了，要加奖品库存怎么办？ + +- 问题1；[https://bugstack.cn/md/algorithm/logic/math/2022-11-05-fibonacci.html](https://bugstack.cn/md/algorithm/logic/math/2022-11-05-fibonacci.html) +- 问题2；还有，预生成中奖结果。比如微信春晚红包，提前把奖品随机好，写入到个人记录。用户开奖只是到点查看结果。【如果提到高性能中间件这个可以再继续让面试聊下，因为有可能问题和听者理解的不一致了】 +- 问题3；这个课程里提供了总、月、日库存。 +- 问题4；有次数锁、有权重，可以避免一开始就中一等奖。也是课程的。 +- 问题5；算法如；线性同余生成器、梅森旋转算法、洗牌算法、加权随机。 +- 问题6；黑名单一般会设定人群标签，写入到 Redis 使用。之后库里只是配置了一个人群标签的标识。 +- 问题7；incr 和总量比，decr 和 0 比。decr 适合过程中不允许补充库存的。incr 可以在过程中添加库存，因为总量可以增加对比。【问题8】 + +### 【携程】7. 我跟他说用户在抽奖系统用积分兑换抽奖机会，我方会向mq发消息，积分微服务那边（不是我们组负责的）拿到消息之后扣减会员的积分，他问我： + +- 你为什么在这种积分扣减用mq？我说流量削峰，他说这不是关键。 +- ️如果用户用脚本频繁兑换抽奖机会，你们怎么应对的。 +- 果下游服务迟迟没有对mq进行消息消费，你们怎么处理的？你假设作为系统的架构者，是怎么监控这种状况的。 + +解答：[https://t.zsxq.com/0jjqr](https://t.zsxq.com/0jjqr) + +1. 当你描述为积分和抽奖是单独的系统，你要生成兑换商品订单，拿订单的唯一单号，rpc/http 调用积分系统扣减积分，返回一个交易单号和时间。【如果是微信、支付宝类支付，就需要等待回调，因为还要走支付渠道很多流程，没法直接返回】 +2. 你通过积分支付接口返回的信息开始变更订单记录，发放抽奖次数。 +3. 用户是用自己的积分兑换的，账户会进行额度拦截。之后接口会配置频次拦截【大营销第4阶段有这个设计】 +4. 系统是有边界管控的，在实际工作中，当前的系统要保证发送mq，下游的系统要保证消费mq。mq的消费会有监控配置，比如日常每分钟100次，如果连续n次在n分钟内，低于80次或者高于140次，则进行报警。这样就可以监控到了。 + +### 【其他】8. 关于上下游交互的问题 + +1. 每次面试官都会问一嘴，基于ratelimiter是做单机限流吗？ +实际生产中主要是使用分布式限流吗，为什么要基于分布式做呢，单机限流满足不了需求吗，分布式限流具体实现方式是什么呢，基于redis、zookeeper自己实现还是基于限流框架做呢 +2. 限流、降级有必要做到外部服务粒度的嘛？（例如有3个外部系统，有必要为每个系统单独限流、降级吗，例如只是不提供给某个系统服务） +3. 奖品单状态的变更，我还是有一点模糊，如果是下游发奖，那下游应该是不能访问奖品服务的库吧，那下游发完奖如何更新奖品单状态呢？会有回调接口或者是下游再发一个发奖完毕的消息吗？ +4. 抽奖活动会和业务系统绑定吗？是不是得在活动表加一个字段，然后鉴权的时候只能调用当前系统的抽奖活动 + +解答：[https://t.zsxq.com/7uTKz](https://t.zsxq.com/7uTKz) + +### 【网易】9. 在抽奖过程时，需要预热处理，可是不可能让用户点击活动装配呀，这个问题你怎么解决? + +第一个视频里提到了，是在活动运营配置后，可以审核通过就预热了。等待活动到了有效期就可以使用了。 + +### 【网易】10. 在抽奖的结果中，如果一个用户在前端抽到了一个奖品，对用户是可见的。可是在扣减库存时，却发现没有了对应的库存，此时应该怎么办? + +库表设计中，抽奖的每条策略是有库存限制的，抽到后才会展示给用户。如果库存不足直接就是兜底积分了。这个也有人遇到过反过来问的，为什么要给策略上也加库存，直接奖品加库存不就可以。其实是不可以的。 + +### 【其他】11. 既然为了想承受更高并发使用redis做库存扣减，那生成奖品id后续要等中奖订单入库才能给用户展示结果吗？那用redis做库存扣减不就没意义了 + +最核心的其实是，如果没有redis做库存扣减，就要数据库里的一个库存记录做扣减。那么就会有成千上万条的请求在同一个表行记录开始独占竞争加锁，其余的请求进入等待，直至耗尽所有数据库连接。那么整个系统服务也就会被拖垮，一个普通的查询也会从原来的几十毫秒变成到一分钟也拿不到结果了。 + +使用redis，就是为了解决这个事情。之后在写入库里的记录，都是无竞争的。那么就不会让数据库被夯住。可以快速被处理。在大厂的数据库配置，基本这类操作不会被 redis 慢多少。 + +解答：[https://t.zsxq.com/kCjDL](https://t.zsxq.com/kCjDL) + +### 【其他】12. 你说你的系统压测指标是3000QPS（简历上我写了3000QPS压测指标），你认为你做的是这个系统压测到3000的时候，他的瓶颈在哪里？ + +1. 你应该是描述的单个接口压测，3000qps，qps 指查询，这个过程没有写库，没有事务的操作。瓶颈往往在于接口串联的多，也包括rpc微服务，层层调用带来的性能损耗。其中性能损耗最大的，一般是风控类接口。之后优化可以用多线程并行调用，之后在统一把数据合并处理。你在回答的时候，可以讲，之前是多少qps，响应时间tp99、tp999、max是多少，之后经过与外部接口的协调，增加redis缓存预热，以及你在把接口通过多线程异步并行查询，提高了接口性能，增加了qps指标。另外，还有是单机还是分布式，每台机器配置的jvm，比如原来的指标配置是什么样，这次配置的是多少（这些可以从普罗米修斯监控得出，之后整理成回答）如果回答数据类的，一定要压测。 + +2. 抽奖用的是你的个人库存，这部分可以加分布式锁，一个活动，一个sc场景，只能一个抽奖进行中活动，这样组合一个key加分布式锁就可以了。 + +3. incr 这个星球里有很多资料了，分段锁接近于无锁化，乐观锁。而以前的直接加锁，锁全活动是独占锁，悲观锁。我们要的目的就是接近于不加锁，并且保证性能。另外 lua 脚本实际压测性能并不好。incr + 锁，尽可能避免超卖。但不加锁，基本等于裸奔，虽然大概率不出问题，但出问题是不可知的。我们做系统设计，就要考虑它可能存在的风险，尽可能降低，而不是等待它发生。资料；https://t.zsxq.com/F1J0L - 这里的话术可以使用「海恩法则、薛定谔的猫、墨菲定律、蝴蝶效应及熵增原理」。 + +- 解答：[https://t.zsxq.com/Gdttm](https://t.zsxq.com/Gdttm) +- 扩展：[https://t.zsxq.com/FWBzl](https://t.zsxq.com/FWBzl) + +>问题1：加分段锁的目的是为了什么？ + +答：核心目标是为了防止低概率下集群、主从故障导致的超卖，做一个兜底逻辑。 + +>问题2：如果不需要补库存，分段锁是不是可以不用加？ + +答：即使不考虑手动补库存的情况，如果集群、主从故障，不加分段锁还是会可能超卖的，所以这里的分段锁不单单是为了补库存的场景而设计。 + +>问题3：那直接 incr 不可以吗？ + +答：在 redis 集群模式下，incr 请求操作可能发生网络抖动超时返回。这个时候 incr 有可能成功，也有可能失败。可能是请求超时，也可能是请求完的应答超时。那么 incr 的值可能就不准。【实际使用中10万次，可能会有10万零1和不足10万】，那么为了这样一个临界状态的可靠性，所以添加 setNx 加锁只有成功和失败。 + +还有一种情况是主从切换的时候，如果主节点的 incr 还没同步到从节点，主节点挂了，丢失了部分未同步的数据，incr 的值从 8 变成 6，如果没有加锁就可能超卖，属于极端情况下的一种兜底策略，有 setNX 锁拦截后，会更加可靠。 + +>问题4：那如果考虑集群故障，机器挂掉的情况，setNX 不也会报错吗？ + +答：setNX 如果失败了，就直接报错返回 "活动库存不足" 即可，也就是可能会导致少卖，但是不会导致超卖。并且 incr 和 setNX 的 key 不同，incr 的 key 和滑块锁的 key 大概率不在同一节点上，从而双重保证，如果 senNx 的 key 和库存的 key 节点都 down 机了，那这里确实有超卖的可能，不过这个概率可以低到忽略不计。 + +>问题5：decr 和 incr 两种扣减方式有什么不同？ + +答：二种方式都可以，decr 适合固定库存场景，和 0 对比，incr 适合可以补库存的场景，和库存总量对比。 + +>问题6：那为什么要分段，直接对一个 key senNX 不可以吗？ + +答：分段锁的话，setNX 因为是非独占锁，所以 key 不存在释放。setNX 的 key 的过期时间可以优化为活动的有效期时间为结束。而独占锁，其实你永远也不好把握释放时间，因为秒杀都是瞬态的，释放的晚了活动用户都走了，释放的早了，流程可能还没处理完。 + +>问题7：incr 扣减模式下，如果同一个用户并发进来，那么缓存中的库存就会+并发数，但实际这个用户只会领取到一条数据，所以就要恢复并发数-1的库存数量。这样种情况并不是 redis 不稳定导致的，而是同一用户并发导致的，应该及时去恢复数据啊，不然的话缓存中的库存直接一下就给一个用户并发干没了，然后再去恢复，效率太低了吧？ + +答：不需要恢复，还是回到上面，核心是保证不超卖，关于库存恢复，一般这类抽奖都是瞬态的，且 redis 集群非常稳定。所以很少有需要恢复库存，如果需要恢复库存，那么是把失败的秒杀 incr 对应的值的 key，加入到待消费队列中。等整体库存消耗后，开始消耗队列库存，等补偿恢复，活动已经基本过去了。所以超卖，快速结束是最好的。这个一般是基于运营策略配置何种方式恢复库存，可以失败的专门扫描到恢复库存列表用于消耗，也可以不恢复（因为失败概率很低，也允许不超买即可）。 + +###

+ +
+ +**为什么毕业生，画不出来这些图？** + +其实不只毕业生，很多工作1-3年的也画不出这些系统的架构图。主要是因为，在校的时候没有学过，市面的一些简单学习项目也都是 CRUD 的 demo 级别项目，工作了以后如果又是一些小厂，大部分就是完成功能需求而已。所以很多人压根就没有画过这些图。 + +但作为程序员👨🏻‍💻这个行业的伙伴，如果还想多职业生涯走的更长，也多赚点米，那么就需要好好的在一个大型项目中锻炼这些画图的技能。因为一图胜前言，有时候图好，前途就好！ + +那一个系统都会做出哪些个设计图呢？这里会包括；`系统架构图`、`业务拓扑图`、`用户用例图`、`业务流程图`、`系统建模图`，之后就是细分实现功能的 UML 流程图。这里小傅哥会以此的给大家做绘制和讲解，这趟车🚗你可以学习到很多！ + +>文末提供了本次分享系统设计图对应的系统工程全套代码、文档、视频和面试官以及简历资料。 + +## 一、系统的场景 + +这是互联网公司C端场景，峰值流量最高的一套**营销类业务系统**，业务涵盖；`抽奖`、`活动`、`积分`、`返利`、`兑换`，这些核心的业务流程。像是在`抖音商城`、`京东金融`、`滴滴出行`、`拼多多`，都有这样业务场景。如图； + +
+ +
+ +整个系统是一个包括 `前后端 + Dev-Ops` 的全栈式综合编程实战项目，基于 React + SpringBoot + 分布式技术栈 + Nginx + Grafana + Docker 云服务，开发、部署、上线、监控，全体系技术运用构建。 + +> 接下来，小傅哥就给大家分别的展示出各项设计图，包括；`系统架构图`、`业务拓扑图`、`用户用例图`、`业务流程图`、`系统建模图`。 + +## 二、系统架构图 + +**软件架构**是有关软件整体结构与组件的抽象描述，用于指导大型软件系统各个方面的设计。软件架构会包括软件组件、组件之间的关系，组件特性以及组件间关系的特性。软件架构可以和建筑物的架构相比拟。软件架构是构建计算机软件，开发系统以及计划进行的基础，可以列出开发团队需要完成的任务。 + +
+ +
+ +- 这是一套大营销系统的分布式架构设计图，从前端到负载，从服务治理到后端分布式技术栈体现，从应用到部署和监控的全体系展示。在这样一套系统架构中，你可以清楚的知道从前到后的流程、各项分布式技术栈的用途、整个系统的脉络关系。所以这样的一个图可以清晰的指导我们做系统的搭建。 +- `佛瑞德·布鲁克斯`在写作《人月神话》一书时提及：软件系统的架构是有关软件系统该作什么以及不该作什么的实体观点。这些观点应和软件的实现分开。架构师的角色是“观点的看守者”，确认系统中增加的部分是符合此架构，因此可以保有概念完整性 +- 另外程序员`马尔文·康威`在1967年论文发表了康威定律，其中提到一个组织开发的软件，其架构会反映其组织架构。佛瑞德·布鲁克斯在写作《人月神话》一书时，就在书上时提到此例子，命名为“康威定律”。 + +## 三、用户用例图 + +用例图（英语：use case diagram）是用户与系统交互的最简表示形式，展现了用户和与他相关的用例之间的关系。通过用例图，人们可以获知系统不同种类的用户和用例。用例图也经常和其他图表配合使用。 + +- 用例图，也可以等同于是用户故事（英语：User story）（软件开发和项目管理中的常用术语），主旨是以日常语言或商务用语撰写句子，是一段简单的功能表述。以客户或使用者的观点撰写下有价值的功能、引导、框架来与使用者进行互动，进而推动工作进程。可以被认为是一种规格文件，但更精确而言，它代表客户的需求与方向。以该用户故事来反应对象在组织内的其工作职责、范围、需要进行的任务等。用户故事在敏捷开发方法中用来定义系统需要提供的功能和实现需求管理。 +- 尽管用例本身会涉及大量细节和各种可能性，用例图却能提纲挈领地让人了解系统概况。它为“系统做什么”提供了简化了的图形表示，因此被誉为“搭建系统的蓝图”。 + +
+ +
+- 用例图是研发进入设计阶段第一个图，通过用例图了解整个系统中发生的流程行为。这个图虽然很粗，但非常适合做后续的设计指导。 + + +## 四、业务拓扑图 + +系统业务拓扑图通常是指系统中各个组件和业务流程的可视化表示。这类图示有助于理解和分析系统如何运作、各组件之间的关系、数据流动的路径以及可能的瓶颈或失败节点。 + +
+ +
+ +- 业务拓扑图，展示出了业务实现中的关系模型，包括整个系统会从哪里展示，包括了哪些核心业务功能和执行的链路。以及数据的走向。 +- 有了系统业务拓扑图，开发者、系统架构师和运维人员可以更直观地理解系统的结构和业务逻辑，从而更有效地进行设计、部署、监控和故障排除。 + +## 五、四色建模图 + +如果系统是 DDD 开发的，还需要做四色建模。在使用 DDD 的标准对系统建模前，一堆人要先了解 DDD 的操作手段，这样才能让产品、研发、测试、运营等了解业务的伙伴，都能在同一个语言下完成系统建模。 + +- 蓝色 - 决策命令，是用户发起的行为动作，如；开始签到、开始抽奖、查看额度等。 +- 黄色 - 领域事件，过去时态描述。如；签到完成、抽奖完成、奖品发放完成。它所阐述的都是这个领域要完成的终态。 +- 粉色 - 外部系统，如你的系统需要调用外部的接口完成流程。 +- 红色 - 业务流程，用于串联决策命令到领域事件，所实现的业务流程。一些简单的场景则直接有决策命令到领域事件就可以了。 +- 绿色 - 只读模型，做一些读取数据的动作，没有写库的操作。 +- 棕色 - 领域对象，每个决策命令的发起，都是含有一个对应的领域对象。 + +
+ +
+ +- 系统建模后可以细分出系统开发中要实现的领域，包括；返利、活动、策略、奖品，兑换可以是单独的领域也可以合并到返利实现。 +- 具体的建模过程可以阅读 [《架构：DDD 领域驱动设计，战略、战术、战役，落地指引规范》](https://bugstack.cn/md/project/big-market/ddd.html) + +## 六、业务流程图 + +系统业务功能流程图（Business Functional Flow Diagram，BFD）是一种用于描述和展示系统内业务功能及其之间关系的图形化工具。它通常用于系统分析和设计阶段，以帮助理解和沟通业务流程、功能要求以及系统的各个组件如何协同工作。 + +
+ +
+ +- 在该流程中，详细的展示出了系统的业务流转关系，从1~6的用户行为，全面的展示出了系统中的流程动作。怎么抽奖、怎么返利、怎么兑换积分。 +- 画这个图到时候，首先，需要识别系统中的主要业务功能。这些业务功能通常可以通过业务需求文档、需求分析会谈以及与业务用户的交流中得出。之后，识别各业务功能之间的关系和依赖性。这包括理解哪些业务功能依赖于哪些其他功能，以及它们如何相互作用。最后，绘制流程图，以图形方式展示业务功能和它们之间的关系。 + +## 七、工程分层图 + +工程的分层有 MVC 三层架构、DDD 四层架构，其实 DDD 不能只是说它是架构，因为用于承载 DDD 的架构是；整洁架构、洋葱架构、六边形架构、菱形架构这些。 + +
+ +
+ +- 六边形架构，会把本身提供到外部的放到trigger，让接口调用、消息监听、任务调度，都可以统一一个入口处理。而对于需要调用外部同类的能力统一放到 infrastructure 基础设施层，包括；数据库、缓存、配置、调用其他方的接口。 +- querys 模块是为了提供查询设计的模块，这样一些基本简单的查询就不需要再走到 domain 领域层了。 +- 更多关于 DDD 的工程模型，可以在 [bugstack.cn](https://bugstack.cn) 进入《路书》中阅读9篇系统架构部分。 + +## 八、扩展类知识 + +这是小傅哥为大家提供的一套综合锻炼编程能力的实战项目大课。全程视频手把手，一个个章节、一步步流程的带着大家从0到1，需求分析、工程设计和代码实现。 + +课程完成后，有可参考简历编写模板、简历面试问题汇总、项目延展性思考和分析，以及项目中的架构、设计模式在场景方案中的运用。 + +- 课程目录：[https://bugstack.cn/md/project/big-market/big-market.html](https://bugstack.cn/md/project/big-market/big-market.html) +- 系统建模：[https://bugstack.cn/md/project/big-market/ddd.html](https://bugstack.cn/md/project/big-market/ddd.html) +- 简历参考：[https://bugstack.cn/md/project/big-market/notes.html](https://bugstack.cn/md/project/big-market/notes.html) +- 面试问题：[https://bugstack.cn/md/project/big-market/notes.html](https://bugstack.cn/md/project/big-market/notes.html) diff --git "a/docs/md/project/big-market/web/\347\254\2541\350\212\202\357\274\232React\345\267\245\347\250\213\345\210\233\345\273\272\345\222\214\346\212\275\345\245\226\347\273\204\344\273\266\344\275\277\347\224\250.md" "b/docs/md/project/big-market/web/\347\254\2541\350\212\202\357\274\232React\345\267\245\347\250\213\345\210\233\345\273\272\345\222\214\346\212\275\345\245\226\347\273\204\344\273\266\344\275\277\347\224\250.md" new file mode 100644 index 000000000..c3ea21f50 --- /dev/null +++ "b/docs/md/project/big-market/web/\347\254\2541\350\212\202\357\274\232React\345\267\245\347\250\213\345\210\233\345\273\272\345\222\214\346\212\275\345\245\226\347\273\204\344\273\266\344\275\277\347\224\250.md" @@ -0,0 +1,32 @@ +--- +title: 第1节：React工程创建和抽奖组件使用 +pay: https://t.zsxq.com/17Jfuonzc +--- + +# 《大营销平台系统设计实现》 - 前端页面 第1节：React工程创建和抽奖组件使用 + +作者：小傅哥 +

+ +
+ +- 整个流程其实简单，复杂点在于怎么提供一个异步响应接口，并怎么把这个需要一堆的调用代码的实现，分配到各个类里去处理。 +- 而同时小傅哥也希望把另外一套DDD架构，通过这个项目需求给大家展示出来。 + +## 三、架构讲解 + +### 1. 模型抽象 + +小傅哥提到了一个简单的开发模型。开发代码可以理解为：`“定义属性 -> 创建方法 -> 调用展示”`但这个模型结构过于简单，不太适合运用了各类分布式技术栈以及更多逻辑的 DDD 架构。所以在 DDD 这里，我们把开发代码可以抽象为：`“触发 -> 函数 -> 连接”` 如图； + +
+ +
+ +- DDD 架构常用于微服务场景，因此也一个系统的调用方式就不只是 HTTP 还包括；`RPC 远程`、`MQ 消息`、`TASK 任务`，因此这些种方式都可以理解为触发。 +- 通过触发调用函数方法，我们这里可以把各个服务都当成一个函数方法来看。而函数方法通过连接，调用到其他的接口、数据库、缓存来完成函数逻辑。 + +接下来，小傅哥在带着大家把这些所需的模块，拆分到对应的DDD系统架构中。 + +
+ +
+ +### 2. 架构分层 + +如下是 DDD 架构的一种分层结构，也可以有其他种方式，核心的重点在于适合你所在场景的业务开发。以下的分层结构，是小傅哥在使用 DDD 架构多种的方式开发代码后，做了简化和处理的。右侧的连线是各个模块的依赖关系。接下来小傅哥就给大家做一下模块的介绍。 + +
+ +
+ +- **接口定义 - xfg-frame-api**：因为微服务中引用的 RPC 需要对外提供接口的描述信息，也就是调用方在使用的时候，需要引入 Jar 包，让调用方好能依赖接口的定义做代理。 +- **应用封装 - xfg-frame-app**：这是应用启动和配置的一层，如一些 aop 切面或者 config 配置，以及打包镜像都是在这一层处理。你可以把它理解为专门为了启动服务而存在的。 +- **领域封装 - xfg-frame-domain**：领域模型服务，是一个非常重要的模块。无论怎么做DDD的分层架构，domain 都是肯定存在的。在一层中会有一个个细分的领域服务，在每个服务包中会有【模型、仓库、服务】这样3部分。 +- **仓储服务 - xfg-frame-infrastructure**：基础层依赖于 domain 领域层，因为在 domain 层定义了仓储接口需要在基础层实现。这是依赖倒置的一种设计方式。 +- **领域封装 - xfg-frame-trigger**：触发器层，一般也被叫做 adapter 适配器层。用于提供接口实现、消息接收、任务执行等。所以对于这样的操作，小傅哥把它叫做触发器层。 +- **类型定义 - xfg-frame-types**：通用类型定义层，在我们的系统开发中，会有很多类型的定义，包括；基本的 Response、Constants 和枚举。它会被其他的层进行引用使用。 +- **领域编排【可选】 - xfg-frame-case**：领域编排层，一般对于较大且复杂的的项目，为了更好的防腐和提供通用的服务，一般会添加 case/application 层，用于对 domain 领域的逻辑进行封装组合处理。 + + diff --git "a/docs/md/project/chatgpt/api/\347\254\2545\350\212\202\357\274\232\345\205\254\344\274\227\345\217\267\345\217\221\351\200\201\351\252\214\350\257\201\347\240\201\351\211\264\346\235\203\347\231\273\345\275\225.md" "b/docs/md/project/chatgpt/api/\347\254\2545\350\212\202\357\274\232\345\205\254\344\274\227\345\217\267\345\217\221\351\200\201\351\252\214\350\257\201\347\240\201\351\211\264\346\235\203\347\231\273\345\275\225.md" new file mode 100644 index 000000000..c18c7663e --- /dev/null +++ "b/docs/md/project/chatgpt/api/\347\254\2545\350\212\202\357\274\232\345\205\254\344\274\227\345\217\267\345\217\221\351\200\201\351\252\214\350\257\201\347\240\201\351\211\264\346\235\203\347\231\273\345\275\225.md" @@ -0,0 +1,41 @@ +--- +title: 第5节：公众号发送验证码鉴权登录 +pay: https://t.zsxq.com/10sh5hUmt +--- + +# 《ChatGPT 微服务应用体系构建》 - chatgpt-api 第5节：公众号发送验证码鉴权登录 + +作者：小傅哥 +

博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +于5.1启动，耗时3个多月开发的 OpenAI 项目，**终于到了上线对外的时候**。可能很多伙伴会想到，Github 不是有不少的开源项目吗，为啥还自己做？ + +为啥🤔。嗯，好问题！因为我是一个程序员👨🏻‍💻，我需要对各项技术的实现方案有深度的理解，我不能在工作或者面试中被提问的时候，说你去看开源项目吧。 + +此外大部分 Github 的开源项目主要以前端为主，并没有一个前后端结合的开发。而实际上，当我们真的需要在业务场景来使用时，就不只是前端页面，还需要在后端做各项的控制和管理。而这样的架构设计，就势必会涉及到；`前后端分离`、`前端工程架构`、`后端工程架构(DDD)`、`登录授权鉴权`、`大模型SDK实现(okhttp)`、`流式异步响应开发对接`、`库表字段索引精细设计`、`API多渠道路由`、`内网穿透服务测试`、`前后端镜像打包`、`docker-compose 服务部署和回滚策略`、`公众号验签配置`，等等技术知识的运用。 + +**所以**，你跟开源项目学的是简单的应用，跟小傅哥学习；`学的是架构设计的魅力`、`学的是技术实现的巧妙`。学的是，让你在晋升、述职、面试，时交流的底气。**那么现在小傅哥把这样一个上线项目，拆分成一个个章节学习，让你也能具备这样的能力。** + +## 一、先看效果 + +**体验地址：[openai.itedus.cn](https://openai.itedus.cn/)** + +

+
+
+ +## 二、再说流程 + +当一个项目引入后端能力以后，就可以扩展非常多的能力。而所有的控制都是在做用户的行为处理，而这些行为就是业务需求。当不同的码农面对相同的业务，写出的代码可就不一样了。所以小傅哥也是希望让你能学习到**怎么架构和编码出高质量的代码**。 + +📢 我告诉你，当前的需求就是；公众号扫码获取验证码登录，登录后访问 OpenAI 服务，访问后需要根据是用户绑定的APIKey还是系统APIKey分别调用，如果是系统APIKey则需要限制调用次数，而用户自己绑定的则不需要。此外调用的 OpenAI 模型和渠道不同，需要进行判断和处理。那么这样的代码你想怎么写？🤔 会不会写出 if···else 的面条代码？ + +如果你不想写出面条代码，那么就看看小傅哥给你设计的流程图结构。如下； + +
+ +
+ +- 首先，在这套流程中，小傅哥将核心业务和支撑核心业务的分支流程进行拆解。一切的分支都是为了支撑主干流程运行，而分支的存在和去除，都应以模块插件的方式进行使用。这样会更好的维护和使用。 +- 之后，我想说。写代码就像擦屁屁的纸，80%的面积都是保护手的。所以这除了那20%的核心点以外，要让那支撑系统运行的 80% 分支逻辑，采用设计模式进行进行分治和抽象的设计实现。 +- 所以，这里有了路由模块和规则引擎的使用。因为他们可以更好的被添加和移除。而每次变动的时候，也都是固定范围的变动，不会让整体流程都陷入测试风险中。 + +**所以**，你还觉得写代码就只是if···else吗，这哪是写代码，这TM是老子在用代码构建一个世界！ + +## 三、之后上线 + +一个系统的上线对外，会有太多太多的细节要考虑。而这样的内容，只有实践了才能真的吸收这些知识。尤其是出一些事故时，都是留下一个个技术成长的故事。 + +
+ +
+ +那么我们现在以 OpenAI 个人上线对外一个项目的背景进行思考 🤔，看看会有哪些点需要处理； +1. 技术栈的使用，不宜过多。要尽量减少运维成本。比如你可以使用 Guava 替代 Redis 使用。 +2. 数据库可以考虑单独购买，避免数据丢失。但同时也需要考虑，如果数据丢失，用户可以根据自己的加密卡Key进行重新绑卡。 +3. 因为本身服务器的成本就比较高，所以尽量控制被白piao。比如任何一个Key都可以在你部署的服务上使用，其实意义不大。可以通过只授权加密 Key 的方式进行使用。 +4. 此外要考虑，多种的调用渠道，如果某个挂了。要能替换对应渠道的访问地址，所以还需要把渠道对应的地址做成可配置的，之后用户写入库里，写入的只是渠道码这样就可以方便替换。 +5. 打包部署上线，一定要先在本地测试验证，验证完全没问题在上线。否则你就单台服务器没有负载能力的情况下，基本就要挂了。 +6. 如果你在本地测试仍不放心，可以修改一个端口和一个 docker-compose-pre-v1.0.yml 进行部署测试。可千万别修改原来正式对外的 compose 直接部署，这会出问题的。 +7. 要有一个可以回滚的处理，可以配置 docker-compose-prod-v1.0.yml 版本的添加。如果1.1版本出问题，可以快速使用 1.0 版本重新部署。 +7. 数据库表的使用，要注意字段的设计，索引的设计，否则就你那一卡拉米资源的数据库配置，真的可能因为你没有索引被打挂。此外可得把用户名和密码设计的强悍一些，别被比特币勒索。 +7. 定期导出 MySQL 数据库表数据，或者有自动备份功能的数据库服务器也是可以的。 +8. 因为你的代码，确实是你的代码。这可不是公司的，也不是有别人参与的。所以为了能在迭代或者处理问题的时候，快速解决。一定是要非常好的架构，非常清晰的编码。 + +## 四、系统介绍 + +加入小傅哥的星球【码农会锁】，就可以完整的学习此套项目。另外星球还有，Lottery、API网关、IM、组件开发、插件开发等项目一起学习。 + +
+ +
+ +小傅哥带着大家写的项目，从来不是凑数项目，也从不写一堆的 CRUD 代码。而是按照互联网企业级中所开发项目的模式进行架构、设计和实现。所以你跟着小傅哥学习，学的是编程的思维和编码的能力。如下是系统的架构分层； + +
+ +
+ +- 以上内容，分别包括；API、WEB、SDK，以及 Dev-Ops 部署相关的内容。 +- 所以这套项目的学习，学的是前端、后端、架构、部署、运维等一整套东西，非常具有含金量。 \ No newline at end of file diff --git a/docs/md/project/chatgpt/extra/ChatGPT-v1.2.md b/docs/md/project/chatgpt/extra/ChatGPT-v1.2.md new file mode 100644 index 000000000..c0617cd34 --- /dev/null +++ b/docs/md/project/chatgpt/extra/ChatGPT-v1.2.md @@ -0,0 +1,179 @@ +--- +title: 又完结一个新项目，小而美、小而精！ +lock: no +--- + +# 又完结一个新项目，小而美、小而精！ + +作者：小傅哥 +

博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +经过10.1国庆假期💐，小傅哥在 [星球：码农会锁](#) 发布的 OpenAI 课程项目中，新嵌入了一个小型电商系统。支持用户商品下单，微信扫码支付，异步额度充值的全流程实现。**而且这套支付已经上线运行，卷的就是真实！** + +
+ +
+ +此项目对接支付开发小电商，会采用DDD领域分层实现，非常具有学习价值。 + +此前，在面试中我看到过众多伙伴写的电商或外卖项目中，写到了支付。也因此拉高了对求职者面试的兴趣。但实际面试下来，大部分校招简历的支付都是模拟的支付，或者说根本没有对接过支付。从而导致面试中，问到；`支付流程`、`掉单处理`、`发货补偿`等真实场景，都没法回答。所以也就高开低走了！ + +那么鉴于这样的情况，小傅哥就想在一个项目中，缩小电商场景后，重点突出支付流程的设计实现。并且在整个支付的设计中，采用领域驱动设计的思想进行设计和实现。让你既有丰富的业务流程知识、也有厚实的方案实现。 + +**当我拿出提交记录，阁下又该如何应对！🤨** + +
+ +

+ +
+ +### 2. 支付页 + +

+ +
+ +- 左侧，是整个项目所涉及的领域服务，包括；生成式服务、权限校验、微信支付、用户账户、订单交易、商品。构成整个服务功能。 +- 右侧，以用户视角下，了解各个领域的上下文关系。从微信对接、权限校验、再到生成式服务和账户域使用。以及本节要实现的订单交易域。 + +## 二、下单支付，怎么设计？ + +做业务功能开发，我们可以先只思考核心的主流程。那么本节要做的功能，最核心的就是用户选择商品下单，之后生成一个支付URL，用户扫码支付。再接收到支付成功回调后，把用户购买的订单发货【额度充值】。 + +
+ +
+ +这是一个非常核心的主流程。有了主流程，我们在思考下可能出现的异常流程。如； + +1. 用户订单创建成功，但创建支付单 HTTP 超时失败。 +2. 支付回调时，系统宕机或者本身服务出问题。 +3. 支付成功后发送MQ消息，消息丢失，用户支付掉单。 +4. 长时间未支付，超时订单。 + +那么，这些就都是可能出现的异常流程。虽然概率很低，但随着使用规模的增加，很低概率的问题，也会产生较大规模的客诉问题。所以要针对这些流程做补偿处理。 + +
+ +
+ +- 针对1~4提到异常流程，一条支付链路就会被扩展为现在的样子，在各个流程中需要穿插进入异常补偿流程。 +- 用户下单，但可能存在之前下的**残单**，那么就要对应给予补充的流程后，再返回回去。 +- 支付回调，仍然可能有异常。所以要有掉单补偿和发货补偿。两条任务处理。 + +## 三、DDD工程结构设计 + +说了业务流程，又提到了 DDD 领域驱动设计，那么接下来咱们看看系统的工程分层结构。有了这个东西，才能感受到 DDD 的设计。 + +
+ +
+ +- 一个小型充值类电商，至少需要3个表；用户账户、商品表、订单表。那么流程则为，用户选择商品下单，支付成功后对个人账户进行充值使用。 +- 基于这样的流程在工程的 domain 领域中，加入 order 领域表。 +- 就说，学习过的项目，看过的工程结构。有如此清晰整洁的吗？ + +## 四、代码实现设计和细节体现 + +业务流程说了、工程结构看了。接下来要看看代码在DDD模型结构是怎么体现的。 + +

+ - 首先这是我们xxx公司/实践/实训的第一个OpenAI项目，后续势必会有更多的场景以不同的方式接入。包括 SDK 独立接入、API 接口接入、MQ 消息接入，以及使用提供好的服务类接入。所以在这部分设计的时候，我采用了微服务的架构设计，按照职责边界进行拆分设计。 + - 采用 DDD 架构 API，以及便于不同领域模块的独立设计，一个领域就是一个功能域。在功能域中提供模型、仓储、事件、服务。这样可以更好扩展。 + - 鉴于生成式服务的文本生成可能会有不可靠信息，所以对这部分内容添加了敏感词的过滤。并可根据不同场景选择不同范围的敏感词处理。 + - OpenAI 大模型有多种，这部分在架构上设计独立的 SDK，在实现上采用了 Session

注意：你还可以根据项目中提到的各类技术和章节，来编写你的职责。 + +## 三、面试问题 + +谢二机同学你好，你做的这个项目我非常感兴趣，我们公司也有这样的OpenAI 业务对接，正好可以结合你做的这个[《OpenAI大模型项目》](https://bugstack.cn/md/project/chatgpt/chatgpt.html)聊一下。 + +### 1. 你的这个项目的背景和需求来自哪里？ + +**校招身份举例** + +面试官您好，此项目的最核心背景和诉求，是我希望找到一个可以真实锻炼技术应用的场景。并且可以基于此项目的设计、开发、上线、运维等一系列动作，提高编程思维和落地能力。而此项目的只是一个载体，在项目中我所运用到的微信对接、登录鉴权、异步接口、下单支付、异步发货、账户管理等场景可以运用到其他任何一个项目中使用。所以我选择开发 这样一个项目。 + +并且此项目运用了DDD分层架构，领域驱动设计实现，对于各个场景都遵守了设计原则和设计模式，解决各类复杂场景的实现。如；生成式服务流程中运用模板模式、策略模式、工厂模式，解决对话过程中所需的规则过滤、模型校验、账户状态、账户扣减等开发流程。【项目提问过程中，有时候会让绘制下项目的分层结构、核心流程，之后会基于你画的这些进行提问】 + +通过以上项目的学习我锻炼到了相关项目所用到的核心技术使用，架构设计和落地实现。而此项目的学习，也为我以后在工作中解决实际场问题，打下了牢固的基础。 + +### 2. 项目为什么使用DDD架构，有什么好处？ + +首先是 DDD 的结构分层更加清晰（DDD 是一种软件设计方法，软件设计方法涵盖了范式、模型、框架、方法论），与 MVC 相比避免了 PO、VO 对象被乱用的可能。而这也是在 DDD 中将行为和逻辑封装到一个领域内进行处理，也就是常说的充血模型结构。这样的结构方式，就可以更好的做到业务流程松耦合，功能实现高内聚。 + +那么在这个 OpenAI 项目中，按照业务流程涵盖了`鉴权登录`、`OpenAI`、`下单`、`微信`，4个大的核心场景。这4个核心场景恰好是4个领域，每个领域可以独立开发设计，再通过上层进行编排使用。如果是小项目直接由 trigger 触发器层的进行编排，如果是较大型复杂项目可以增加 case 编排层，再由 trigger 层调用。【层之间是防腐，防腐避免了对象和服务被污染】 + +相对比与MVC结构，这样的架构设计，不会因为引入更多的功能，系统的复杂度也随之提高。因为所有的流程都被拆解了，每个功能都聚合到自己的领域内，这样的复杂度不会增加，并且也更好维护。 + +### 3. 充血模型和贫血模型分别合适什么场景？ + +在 DDD 架构中，充血模型，主要的价值在于解决具有生命周期的流程。如生成式对话、商品下单支付、用户登录授权等流程。因为这些流程中具有较复杂的场景模型和唯一ID，所以采用充血模型结构，会很适合的将状态和行为封装到同一的领域包中进行聚合开发实现。这样的实现方式，也为以后扩展、迭代、维护做了良好的基建，避免工程过于腐化。—— `注意关于DDD的知识，可以把这里的5个视频都刷下。` [https://bugstack.cn/md/road-map/mvc.html(opens new window)](https://bugstack.cn/md/road-map/mvc.html) + +而贫血模型则比较适合 Querys 场景，因为这些场景只是数据的汇总查询，没有唯一ID和生命周期。所以比较适合在工程中提供 query 模块，使用贫血模型开发。 + +### 4. 项目开发中你是怎么提交代码的？ + +首先我是在自己的Gitcode仓库中创建了一个空的项目地址，之后复制项目地址 `https://xxxx.git`。在本地创建 OpenAI SpringBoot 工程，以及工程中 app、domain、infrastructure、trigger、types 5个 modules 模块。在之后在 idea 点开 Git 菜单创建本地仓库，再把仓库中需要提交的内容右键 Add 添加。最后 `Ctrl + Shift + K` 推送代码，推送时配置复制的 git 地址。 + +这个过程中我会注意不要把一些本地文件如 `.idea`、`编译文件` 等提交上去，这些文件可以添加到 `.gitignore` 文件中忽略提交。后续的开发中，会按照`时间-姓名-功能`的规范拉取开发分支，编写代码和提交。开发验证完毕后合并 master 分支进行部署。【如果多人开发，可以把开发分支合并到 test 分支进行部署测试】 + +### 5. 这个项目有部署上线吗？怎么部署的，部署后内存占用如何，请描述下。 + +项目上线了，并且对项目部署了 Prometheus + Grafana 监控组件，以及配置了前端百度统计 PV、UV。部署的方式是先购买了一台`2c4g 5M`带宽的云服务器以及申请备案了域名，之后在前后端应用配置 Dockerfile 打包镜像推送到 DockerHub，之后编写 docker compose 含环境（MySQL、Redis等）脚本，在云服务器执行部署的。因为本项目的登录采用了公众号登录，所以在部署后把服务端接口地址，配置到公众号控制台进行验签和接收验证码登录。 + +整个项目部署完成后，占用了53%~61%的服务器内存，Tomcat 配置了最大连接数是250，OpenAI 调用接口熔断为6秒【OpenAi有时候会有超时】，同时在前端也配置了50秒主动断开。压测过接口的响应，按照目前的服务器可以压测到 50 ~ 80 TPS【随着不同的文本量提问，会有波动。OpenAI 响应有时候会需要7-10秒完成】，日常测试接口响应平均值在3~10秒。—— 这些数据来自于压测后 Grafana 监控的展示【星球内提供了 Grafana 监控配置面板】。 + +这里为什么后端有超时熔断，前端也加了50秒超时主动断开。因为 OpenAI 接口的响应是 ResponseBodyEmitter 异步应答，当返回一个数据块以后，代表已经有响应，则不会计算服务端的超时。但第一次应答后，后面的数据如果卡主了，仍可能一直无应答。所以前端加上主动超时断开会更稳妥。【一般情况下，1~5秒，服务端开始应答】 + +### 6. 你的项目对接了哪些 OpenAI？怎么对接的？ + +在项目的开发阶段对接了 ChatGPT 和国内智谱AI ChatGLM，两款AI产品，都有文生文、文生图、多模态的图文理解等功能。对接的方式是采用会话模型（MyBatis Session）流程，使用 retrofit2 + OkHttp3 框架，封装 OpenAI HTTP 接口。提供统一的出入参，并使用工厂模式，构建 OpenAI 启动阶段所需的验证、日志、执行流程。并最终对外提供 OpenAI 会话服务。 + +星球大模型项目的 OpenAI SDK 提供了两种，一种是独立的 ChatGPT-SDK-Java、ChatGLM-SDK-Java，以及一个综合的 OpenAI-SDK-Java 对接了国内外90%的大模型。这里你可以按照自己的学习积累程度来描述。此外这些 SDK 也已经发布到了 Maven 中央仓库，外部人员也可以使用【有不少伙伴参与了 SDK 开发，你也可以讲自己参与了一起开发或者是你独立内部开发的】。 + +### 7. 因为你的项目是前后端分离的，接口跨域怎么做的？ + +首先我们知道，Web跨域（Cross-Origin Resource Sharing，CORS）是一种安全机制，用于限制一个域下的文档或脚本如何与另一个源的资源进行交互。这是一个由浏览器强制执行的安全特性，旨在防止恶意网站读取或修改另一个网站的数据，这种攻击通常被称为“跨站点脚本”（Cross-Site Scripting，XSS）。 + +所以在我的前后端分离项目中，通过配置 @CrossOrigin 注解来解决跨越问题。开发阶段 `Access-Control-Allow-Origin: *`、上线阶段 `Access-Control-Allow-Origin: https://gaga.plus` + +### 8. 请描述下商品下单支付场景。以及怎么保证的补偿。 + +下单支付场景在整个项目中是一块非常核心的流程，首先是系统设计采用了 DDD 架构，对商品下单按照业务流程拆解出来了单独的领域模块。在设计实现上，以购物车为下单入参的实体对象，出参为支付单实体。保存的是订单的聚合信息。 + +因为本身下单是一个较为复杂的流程，所以在编码实现上采用了模板模式，定义出下单的标准过程。商品下单的流程需要先查询是否存在`已下单未支付`和`已下单但无支付单`的订单，对这样两种订单分别进行处理。已下单未支付，在有效期内未关单的直接返回给用户直接支付。已下单但无支付单则调用(微信/支付宝沙箱/蓝兔)创建支付订单，保存库表记录后返回给前端用户进行支付。此外的流程则直接执行购物车商品ID查询，组装聚合订单数据，创建支付单，保存库表记录和返回给用户。在用户支付完成后，接收支付回调消息，推送（MQ/Redis发布订阅/Guava事件）信息，由系统中 trigger 模块下的监听处理接收支付成功消息，完成商品的发货处理。 + +那么这里可能发生的调单情况，接收回调消息处理失败。则由定时任务扫描库表订单超过15分钟未支付的订单，查询支付平台（微信/支付宝沙箱/蓝兔）是否已支付，如果支付则发送事件消息走后续的补货流程。另外如果超过15分钟以上未支付则进行本地关单，不对支付平台关单（支付平台有自己的时间），这样可以让用户的体验更加舒服。用户超时后支付，仍可以走后续的发货流程。但如果用户刷新界面，则获取创建新的支付单。 + +### 9. 你的订单表也是一个频繁使用的表，那么库表有哪些核心字段，索引有哪些？ + +有用户ID（用的公众号创建的 openid）、商品ID、商品名称、商品金额、订单ID、下单时间、订单状态、支付单类型（微信、支付宝）、支付单号、支付时间、交易单号、交易状态等。表中对订单ID、用户唯一创建了唯一索引，对订单状态和订单时间创建组合索引（提高扫描效率）。 + +### 10. 我看到OpenAI的体验，都是渐进式展示的，这块后端使用了什么接口形式？ + +这部分是使用 SpringBoot 应用提供的 HTTP 接口，返回的是 ResponseBodyEmitter 异步请求处理协议。它是 SpringMVC 所提供的一个异步响应提，当你控制器中返回一个 ResponseBodyEmitter 实例时，Spring MVC 会开启一个异步请求处理，这样就可以在单个请求中发送多个 OpenAI 应答数据块。这样的应答方式是非常适合 OpenAI 这样需要大批量应答数据的场景。此外因为服务端的接口需要 Nginx 转发，所以在 Nginx 端还需要关闭分块解码（chunked_transfer_encoding）、关闭转发缓冲（proxy_buffering）、关闭应答缓存（proxy_cache），这样最终才能是一个渐进式的展示效果。 + +### 11. 你的项目中对接了 ChatGPT 和 ChatGLM 两个模型，那么使用了什么设计模式？ + +关于 ChatGPT、ChatGLM 两个 OpenAI 服务，在项目中定义了一个通信渠道策略接口，接口方法返回统一的格式数据。两款 OpenAI 服务分别实现自己接口处理。之后两个实现的策略模式注入到 Map 中，Key 是一个枚举值。当前端选择不同的模型进行问答时，则根据模型的枚举值从 Map 中选择出对应的策略处理类。这样即使后续拓展其他的 OpenAI 服务也非常容易扩展。 + +### 12. 你在项目中有支付购买的次数，那么对应就会有额度扣减、账户的校验、还有模型的使用类型，这些是怎么实现的？ + +其实除了账户、额度、模型，还有敏感词过滤，在这部分实现中我定义了统一的 ILogicFilter 过滤接口，分别实现不同的过滤诉求。在通过工厂的封装，装配上不同的过滤规则类。用户进行问答后，会对用户的信息分别进行校验。这部分也就是整体 OpenAI 应答中使用的模板、工厂、策略三个设计模式。另外像是这样的调用验证方式，也可以使用责任链的方式处理。 + +之后这里在说下敏感词，敏感词对接了通用的敏感词库，但校验的过于严格同时不是动态的，所以可能不准。后来又对接了[云服务厂商的敏感词过滤服务+图片审核服务](https://bugstack.cn/md/project/ddd-scene-solution/sensitive-word-content-moderation.html)。可以配置广告、舆情、敏感类等都可以配置过滤。 + +### 13. 你是怎么处理异常的？ + +项目中在对接 OpenAI 接口、数据库、缓存、下单调用等，是有可能出现超时、数据接口更新、数据库连接、缓存数据问题等异常，这些异常属于功能异常。是在每个领域模型内可能发生的问题情况。为了让异常保持统一，具备业务语意，所以在 types 层了定义业务异常类 ChatGPTException 和对应的异常码枚举【0000 成功、0001 失败、0002 非法参数、0003 未登录、OE001 商品以下架等异常码】这样就可以标准化返回给前端，针对不同的异常进行信息展示。 + +### 14. 对于返回给前端的接口，返回从出参结果怎么定义的？ + +定义一个 `Response` 添加 code、info、data（枚举类型）参数，统一封装返回结果。这是一个通用设计，应该不止我开发的系统，在我去F12看各个网站的时候，也都是这样统一标准的接口出参。 + +### 15. 公众号里可以对接 OpenAI 自动回复吗？ + +技术上可以对接的，在公众号配置完接口地址验签成功后，就可以接收用户在公众号发送的消息了，之后根据消息内容请求 OpenAI 同步响应接口（也可以是异步接口用 Future 封装）。但这里要注意一点，我是个人公众号开发，不能直接根据用户ID给用户返回信息，只能随着请求一次返回。 + +那么就有可能用户提问后，我调用 OpenAI 接口，因为会需要较长时间返回数据，超过公众号5秒限制，就会得不到数据。所以这块利用公众号的回调机制，5秒+3次，我再后端使用了 CountDownLatch 进行等待，每次都耗时5秒，让公众号第3次在从我的后端获取数据返回。这样可以最大限度保证，一次提问就能获得数据。如果仍然没有获得数据，则提示给用户需要再次提问同样的问题。这个时候我会以问题作为key，获取OpenAI的结果缓存回答给用户。 + +### 16. 应用程序使用了什么数据库连接池，连接数配置如何？ + +配置了 SpringBoot 默认提供的 hikari 连接池。在这之前我也有压测过 [c3p0、dbcp、druid、hikari](https://bugstack.cn/md/road-map/connection-pool.html) 这四款连接池，其中 hikari 是效率最高也是最稳定的，dbcp 相对较差，但如果不使用连接池那么会更差。 + +在我的应用中，配置最小空闲连接数（minimum-idle）是15个，最大连接数（maximum-pool-size）是25个。本身下单接口的平均响应时间是48毫秒，那么 `1秒 / 0.048秒/事务 = 约20.83事务/秒/连接` 也就是 `20.83事务/秒/连接 * 25连接 = 约520.75事务/秒` 这个量级是非常够用的。如果不够可以适当调整连接数大小。 + +### 17. 是否支持分布式部署？ + +是的，一个项目是否支持分布式部署的标识在于它的数据处理是基于单体的还是基于分布式架构的，当一台机器宕机用户在访问时候轮训到下一台机器是否还可以保证业务进行。像是这套项目使用数据库存储用户、账户、商品、下单，在 Redis 存放用户的登录鉴权，那么就可以基于 Nginx 轮训的方式配置多态应用的负载，以此支持分布式架构。 + +### 18. 登录这个业务过程是什么样？ + +企业公众号登录的模型是通过 AccessToken 创建二维码凭证 ticket，并让前端根据凭证创建带参登录二维码。当用户扫码后，对接公众号的服务端会收到回调信息，里面含带了 ticket、openid，那么这个时候就可以创建出 jwt token，前端页面不断通过 ticket 轮训接口获取绑定登录信息即可。 + +另外是个人公众号，它是没有这个权限的。所以只能是让用户在公众号中回复一个固定编号（405），之后服务端接受到固定编号后创建一个唯一登录验证码分配给 openid，用户在通过在页面填写验证码的方式进行登录。填写验证码后，调用服务端接口进行鉴权下发 jwt token 即可。 + +### 19. 如果现在需要让你扩展一个功能，比如接入图片转代码/根据流程图生成代码你会怎么做？ + +这种问题是比较偏开放性的，如果做完项目又结合项目扩展了新的功能，那么回答这类问题会更加得心应手。因为如果你扩展了新的功能，那么你就会知道怎么先去了解需要对接功能的文档【技术调研】，之后结合文档来做对应的案例，让案例覆盖80%你要实现的功能。这样你大概知道了这样东西是可以使用的。 + +接下来梳理代码，设计接入方式和流程，并设计这部分的领域功能，开发完成功能以后开始进行测试验证。这部分是单元测试。测试通过后，开始提供对应的服务的接口，如果是旧的功能扩展，则要考虑兼容性，比如增加了新的模型枚举。可参考案例：[OpenAI + TLDraw 设计图转前端代码](https://bugstack.cn/md/project/ddd-scene-solution/openai-tldraw.html) + +### 20.（开放问题）你在做项目中，什么问题难住你的时间最长，为什么？ + +这是一个开放问题，重点考察你对项目的开发中个人的积累。你可以针对自己的学习过程中，有哪个流程的实现，让你最为有感触，即可回答。 + +这还是比较多的，这个项目有很多的创新设计让代码更好的维护，也有一些取巧的架构方案。比如提到的个人公众号，没有带参二维码就只能通过让用户主动回复生产验证码绑定openid解决，用户在输入验证码进行登录。 + +另外是一个下单的场景，这块的DDD领域设计，到底要用什么作为入参，什么做为出参，进行下单。经过了大量的思考，应该模拟生活中的超时，推着购物车到收银台，创建支付单，扫码登录。所以在系统设计上，以购物车为入参的实体对象，出参为支付单信息【可以扫码支付】，中间的流程用聚合对象保存订单信息。这块的设计，非常清晰和好维护。所以也是一个记忆非常深刻的点。 + +## 四、公司面试 + +### 1. 面试被问openai项目有被问到为什么要使用okhttp3和retrofit，我回答的是用他们来封装对http的调用，面试官说是为什么要选择okhttp3而不是其他的框架？这块我没有接触过其他框架所以回答的不是很好，想问下小傅哥这个问题应该怎么回答 + +- 问题：[https://t.zsxq.com/xXQZr](https://t.zsxq.com/xXQZr) + +1. 面试官要问的是，对于 http 的封装调用，你都了解哪些框架。如；Apache HttpClient、OkHttp、Retrofit、Spring RestTemplate、Spring WebClient、Feign，甚至 hutool 也提供了封装框架。 +2. 之后你要说明，这些框架的优劣势对比，并重点介绍 OkHttp、Retrofit + - 2.1 OkHttp - OkHttp是一个现代的HTTP客户端，它提供了简洁的API和高效的性能。它支持同步阻塞调用和异步调用，并且能够处理SPDY、HTTP/2和WebSocket等协议。 + - 2.2 Retrofit - Retrofit是一个类型安全的HTTP客户端，它通过注解将HTTP API转换为Java接口。它通常与OkHttp一起使用，提供了一个高层次的抽象来处理网络请求。 +3. 对于2中使用的框架，还可以提到目前在微信支付sdk、支付宝sdk，都有使用现代简洁高效的 okttp 框架，对于一些标准度更高的调用则使用 Retrofit，因为他可以简单配置即可使用，屏蔽了对接细节。这与以往的 httpclient 对接方式相比，代码更加简洁，维护成本更低。 \ No newline at end of file diff --git

+ +
+ +**能做一个上线运行的项目，就能多学到一半的知识量**！ + +不上线，就不知道系统需要多大的服务器。不上线，就不能拿到系统的监控数据。不上线，就不清楚系统都有哪些异常。不上线，就不记得要给数据库表做索引优化。说的直白了，没有上线的项目，还只能算是开发阶段的`“技术玩具”`。甚至可能很多系统开发中的流程都是不健全的，缺少细节的处理和流程的补偿。所以，从这个项目开始，小傅哥在星球【码农会锁】带着大家做的项目，都将以上线为最终结果。 + +当我们把系统做完，配置上监控。看到系统负载和调用量那一刻，这个系统才是一个完整的系统。 + +
+ +
+ +那么，接下来小傅哥就对整个系统，做一次从需求到技术落地的复盘总结。让大家可以学习到的更多。 + +>文末有加入学习方式。此外在本项目的业务场景底座上，后续将开启新的上线项目，你猜猜会是什么项目！👍🐂 + +## 一、先说你能学到的 + +首先呢，此项目是一个真实运行在线上有用户使用的系统，所以所有的需求设计和落地实现，都以真实情况进行考量。那么也就是说，所有学习此项目的伙伴，都将学习到真实场景的实战技能。这些技能会通过课程的3个阶段来完成，如下； + +
+ +
+ +- 第1阶段【基础】：01节~23节，学习工程的前后端基础框架搭建开发、实现 OpenAi 异步响应式对话、微信公众号鉴权登录。 +- 第2阶段【深度】：24节~29节，运用模板、策略、工厂，添加多规则过滤引擎，处理白名单、敏感词、账户额度、状态、模型的验证，以及完成核心商品下单、微信支付、账户充值流程。这部分的 DDD 领域模型设计的非常漂亮。 +- 第3阶段【广度】：30节~32节，多渠道策略模型OpenAi对接，系统监控(Prometheus + Grafana)、分布式技术栈扩展，让系统具备分布式部署能力。 + +此项目拆成3个阶段，让大家学习不会有太大压力，如果你着急完成并希望面试，那么完成第1阶段即可编写简历中使用。`整体项目预计在3周~4周可学习完成，如果不编写前端预计在2~3周学习完成。` + +## 二、需求是怎么来的 + +OpenAi 项目，最早来自于小傅哥分别部署过的两个前端开源项目，给大家提供生成式服务。从最开始的部署完就能使用，到后来对接公众号登录引流粉丝关注，再到设计加密ApiKey降低资源投入成本，这样一步步形成了整个需求诉求。 + +
+ +

博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +鉴于智谱AI发布了最新一代 `GLM3.0`、`GLM4.0` 基座大模型，我又要对自己开发的这款开源 [chatglm-sdk-java](https://github.com/fuzhengwei/chatglm-sdk-java) 进行改造了！因为需要做新老接口的模型调用中数据格式兼容，这将是一场`编码设计`与`复杂场景`的对抗挑战。**💐 请看小傅哥如何操刀改造！** + +
+ +
+ +**为什么改造SDK会比较复杂？🤔** + +通常来说，我们开发好一款SDK后，就会投入到项目中使用，而使用的方式会根据SDK的出入参标准进行对接。比如一个接口的入参原本有2个参数，`A String`、`B String` 类型，但现在因为有额外的功能添加，从2个参数调整为3个参数，同时需要对原本的 B 参数 String 类型，扩展为 Object 类型，添加更多的属性信息。同时出参也有对应响应结构变化。 + +那么对于这种线上正在使用又需要改造代码的情况，我们不可能把原有的代码都铲了不要，所以需要做一些优雅的兼容的开发处理。让工程更加好维护、好迭代。 + +**在设计原则和设计模式的锤炼下，写出高质量的代码** + +
+ +
+ +那么，接下来小傅哥就带着大家讲讲这段关于GLM新增模型后 SDK 的重构操作。 + +>文末有整个 SDK 的源码，直接免费获取，拿过去就是嘎嘎学习！ + +## 一、需求场景 + +**智谱AI文档**：[https://open.bigmodel.cn/overview](https://open.bigmodel.cn/overview) + +本次文档中新增加了 GLM-3-Turbo、GLM-4、GLM-4v、cogview，这样四个新模型，与原来的旧版 chatGLM_6b_SSE、chatglm_lite、chatglm_lite_32k、chatglm_std、chatglm_pro，在接口调用上做了不小的修改。因为新版的模型增加了如插件「联网、知识库、函数库」、画图、图片识别这样的能力，所以出入参也有相应的变化。 + +### 1. curl 旧版 + +```shell +curl -X POST \ + -H "Authorization: Bearer BearerTokenUtils.getToken(获取)" \ + -H "Content-Type: application/json" \ + -H "Accept: text/event-stream" \ + -d '{ + "top_p": 0.7, + "sseFormat": "data", + "temperature": 0.9, + "incremental": true, + "request_id": "xfg-1696992276607", + "prompt": [ + { + "role": "user", + "content": "写个java冒泡排序" + } + ] + }' \ + http://open.bigmodel.cn/api/paas/v3/model-api/chatglm_lite/sse-invoke +``` + +- 注意：旧版的调用方式是把模型放到接口请求中，如；`chatglm_lite` 就是放到请求地址中。 + +### 2. curl 3&4 + +```shell +curl -X POST \ + -H "Authorization: Bearer BearerTokenUtils.getToken(获取)" \ + -H "Content-Type: application/json" \ + -d '{ + "model":"glm-3-turbo", + "stream": "true", + "messages": [ + { + "role": "user", + "content": "写个java冒泡排序" + } + ] + }' \ + https://open.bigmodel.cn/api/paas/v4/chat/completions +``` + +- 注意：新版的模型为入参方式调用，接口是统一的接口。此外入参格式的流式可以通过参数 `"stream": "true"` 控制。 + +### 3. curl 4v + +```shell +curl -X POST \ + -H "Authorization: Bearer BearerTokenUtils.getToken(获取)" \ + -H "Content-Type: application/json" \ + -d '{ + "messages": [ + { + "role": "user", + "content": [ + { + "type": "text", + "text": "这是什么图片" + }, + { + "type": "image_url", + "image_url": { + "url" : "支持base64和图片地址；https://bugstack.cn/images/article/project/chatgpt/chatgpt-extra-231011-01.png" + } + } + ] + } + ], + "model": "glm-4v", + "stream": "true" + }' \ + https://open.bigmodel.cn/api/paas/v4/chat/completions +``` + +- 注意：多模态4v模型，content 字符串升级为对象。这部分与 chatgpt 的参数结构是一致的。所以我们在开发这部分功能的时候，也需要做兼容处理。因为本身它既可以支持对象也可以支持 conten 为字符串。 + +### 4. curl cogview + +```shell +curl -X POST \ + -H "Authorization: Bearer BearerTokenUtils.getToken(获取)" \ + -H "Content-Type: application/json" \ + -d '{ + "model":"cogview-3", + "prompt":"画一个小狗狗" + }' \ + https://open.bigmodel.cn/api/paas/v4/images/generations +``` + +- 注意：图片的文生图是一个新的功能，旧版没有这个接口。所以开发的时候按照独立的接口开发即可。 + +--- + +**综上，这些接口开发还需要注意；** + +1. 首先，小傅哥根据官网文档编写了对应的 curl 请求格式。方便开发时可以参考和验证。 +2. 之后，curl 旧版是文本类处理，curl 3&4 是新版的文档处理。两个可以对比看出，旧版的入参是 prompt，新版是 messages +3. 另外，本次API文档新增加了文生图，和4v（vision）多模态的图片识别。 + +> 接下来，我们就要来设计怎么在旧版的SDK中兼容这些功能实现。 + +## 二、功能实现 + +### 1. 调用流程 + +
+ +
+ +如图，是整个本次 SDK 的实现的核心流程，其中执行器部分是本次重点开发的内容。在旧版的 SDK 中是直接从`会话请求`进入模型的调用，没有执行器的添加。而执行器的引入则是为了解耦调用过程，依照于不同的请求模型（chatglm_std、chatglm_pro、GLM_4...），可以调用到不同的执行器上去。 + +### 2. 执行器「解耦」 + +#### 2.1 接口 + +```java +public interface Executor { + + /** + * 问答模式，流式反馈 + * + * @param chatCompletionRequest 请求信息 + * @param eventSourceListener 实现监听；通过监听的 onEvent 方法接收数据 + * @return 应答结果 + * @throws Exception 异常 + */ + EventSource completions(ChatCompletionRequest chatCompletionRequest, EventSourceListener eventSourceListener) throws Exception; + + // ... 省略部分接口 +} +``` + +#### 2.2 旧版 + +```java +public class GLMOldExecutor implements Executor { + + /** + * OpenAi 接口 + */ + private final Configuration configuration; + /** + * 工厂事件 + */ + private final EventSource.Factory factory; + + public GLMOldExecutor(Configuration configuration) { + this.configuration = configuration; + this.factory = configuration.createRequestFactory(); + } + + @Override + public EventSource completions(ChatCompletionRequest chatCompletionRequest, EventSourceListener eventSourceListener) throws Exception { + // 构建请求信息 + Request request = new Request.Builder() + .url(configuration.getApiHost().concat(IOpenAiApi.v3_completions).replace("{model}", chatCompletionRequest.getModel().getCode())) + .post(RequestBody.create(MediaType.parse("application/json"), chatCompletionRequest.toString())) + .build(); + + // 返回事件结果 + return factory.newEventSource(request, eventSourceListener); + } + + // ... 省略部分接口 + +} +``` + +#### 2.3 新版 + +```java +public class GLMExecutor implements Executor, ResultHandler { + + /** + * OpenAi 接口 + */ + private final Configuration configuration; + /** + * 工厂事件 + */ + private final EventSource.Factory factory; + /** + * 统一接口 + */ + private IOpenAiApi openAiApi; + + private OkHttpClient okHttpClient; + + public GLMExecutor(Configuration configuration) { + this.configuration = configuration; + this.factory = configuration.createRequestFactory(); + this.openAiApi = configuration.getOpenAiApi(); + this.okHttpClient = configuration.getOkHttpClient(); + } + + @Override + public EventSource completions(ChatCompletionRequest chatCompletionRequest, EventSourceListener eventSourceListener) throws Exception { + // 构建请求信息 + Request request = new Request.Builder() + .url(configuration.getApiHost().concat(IOpenAiApi.v4)) + .post(RequestBody.create(MediaType.parse(Configuration.JSON_CONTENT_TYPE), chatCompletionRequest.toString())) + .build(); + + // 返回事件结果 + return factory.newEventSource(request, chatCompletionRequest.getIsCompatible() ? eventSourceListener(eventSourceListener) : eventSourceListener); + } + + + // ... 省略部分接口 + +} +``` + +
+ +
+ +在新版的执行实现中，除了 IOpenAiApi.v4 接口的变动，还有一块是对外结果的封装处理。这是因为在旧版的接口对接中使用的是 EventType「add、finish、error、interrupted」枚举来判断。但在新版中则只是判断 stop 标记符。所以为了让之前的SDK使用用户更少的改动代码，这里做了结果的封装。 + +### 3. 注入配置 + +**源码**：`cn.bugstack.chatglm.session.Configuration` + +```java +public HashMap newExecutorGroup() { + this.executorGroup = new HashMap<>(); + // 旧版模型，兼容 + Executor glmOldExecutor = new GLMOldExecutor(this); + this.executorGroup.put(Model.CHATGLM_6B_SSE, glmOldExecutor); + this.executorGroup.put(Model.CHATGLM_LITE, glmOldExecutor); + this.executorGroup.put(Model.CHATGLM_LITE_32K, glmOldExecutor); + this.executorGroup.put(Model.CHATGLM_STD, glmOldExecutor); + this.executorGroup.put(Model.CHATGLM_PRO, glmOldExecutor); + this.executorGroup.put(Model.CHATGLM_TURBO, glmOldExecutor); + // 新版模型，配置 + Executor glmExecutor = new GLMExecutor(this); + this.executorGroup.put(Model.GLM_3_5_TURBO, glmExecutor); + this.executorGroup.put(Model.GLM_4, glmExecutor); + this.executorGroup.put(Model.GLM_4V, glmExecutor); + this.executorGroup.put(Model.COGVIEW_3, glmExecutor); + return this.executorGroup; +} +``` + +- 对于不同的模型，走哪个执行器，在 Configuration 配置文件中写了这样的配置信息。 +- 这样当你调用 CHATGLM_TURBO 就会走到 glmOldExecutor 模型，调用 GLM_4V 就会走到 glmExecutor 模型。 + +### 4. 参数兼容 + +ChatCompletionRequest 作为一个重要的应答参数对象，在本次的接口变化中也是调整了不少字段。但好在小傅哥之前就提供了一个 toString 对象的方法。在这里我们可以做不同类型参数的处理。 + +```java +public String toString() { + try { + // 24年1月发布新模型后调整 + if (Model.GLM_3_5_TURBO.equals(this.model) || Model.GLM_4.equals(this.model) || Model.GLM_4V.equals(this.model)) { + Map paramsMap = new HashMap<>(); + paramsMap.put("model", this.model.getCode()); + if (null == this.messages && null == this.prompt) { + throw new RuntimeException("One of messages or prompt must not be empty！"); + } + paramsMap.put("messages", this.messages != null ? this.messages : this.prompt); + if (null != this.requestId) { + paramsMap.put("request_id", this.requestId); + } + if (null != this.doSample) { + paramsMap.put("do_sample", this.doSample); + } + paramsMap.put("stream", this.stream); + paramsMap.put("temperature", this.temperature); + paramsMap.put("top_p", this.topP); + paramsMap.put("max_tokens", this.maxTokens); + if (null != this.stop && this.stop.size() > 0) { + paramsMap.put("stop", this.stop); + } + if (null != this.tools && this.tools.size() > 0) { + paramsMap.put("tools", this.tools); + paramsMap.put("tool_choice", this.toolChoice); + } + return new ObjectMapper().writeValueAsString(paramsMap); + } + + // 默认 + Map paramsMap = new HashMap<>(); + paramsMap.put("request_id", requestId); + paramsMap.put("prompt", prompt); + paramsMap.put("incremental", incremental); + paramsMap.put("temperature", temperature); + paramsMap.put("top_p", topP); + paramsMap.put("sseFormat", sseFormat); + return new ObjectMapper().writeValueAsString(paramsMap); + } catch (JsonProcessingException e) { + throw new RuntimeException(e); + } +} +``` + +- 如果为本次调整的新增模型，则走新的方式装配参数信息。 +- 通过这样的方式可以很轻松的把以前叫做 prompt 的字段调整为 messages 名称。类似的操作可以看具体的代码。`关于字段的出入参处理，但比较同类，就不一一列举了` + +## 三、功能验证 + +**注意**：测试前需要申请ApiKey [https://open.bigmodel.cn/overview](https://open.bigmodel.cn/overview) 有非常多的免费额度。 + +```java +@Before +public void test_OpenAiSessionFactory() { + // 1. 配置文件 + Configuration configuration = new Configuration();

+ +
+ +在很早之前就关注了智谱Ai(ChatGLM)，也看到官网有一个Java对接的[SDK](https://github.com/zhipuai/zhipuai-sdk-java/)方式。但从前几天开始正式对接发现，这SDK是8月份提交的，10个commit，而且已经2个月没有更新了。所以真的是不少Bug呀，呀，呀！如果不去修改它的SDK代码，就没法对接。如；`ConfigV3类中，拆分ApiKey的操作；String[] arrStr = apiSecretKey.split(".");` 但这里的`.`是正则的关键字，所以根本没法拆分。一起动就报错 `invalid apiSecretKey` 这对于初次对接并且没有看源码的伙伴来说，是不小的炸雷。 + +不过，虽然 SDK 有点赶工，不好用。但不影响`智谱Ai(ChatGLM)`是个好东西。他的官网中有API HTTP 接口对接描述。所以，小傅哥决定跟着按照它的文档写一个能简单对接，代码有干净整洁的 SDK 让大家使用。 + +

+ +
+ +- 工程非常注重会话的设计和使用，因为框架的根基搭建好以后，扩展各项功能就会有迹可循。`大部分代码就是因为早期没有考虑好框架，最后功能来了被填充的很乱。` + +### 2. 会话流程 + +

+ +
+ +但自从有了 OpenAI 以后，我一直惦记着，能不在 Draw.io 这样的工具出设计图后，让 OpenAI 识别自动转换为 HTML 代码。之后把这样的东西做成一整套工具来使用，大大的方便`二把刀前端们`快速完成从UI到HTML的初稿。 + +为此小傅哥基于[开源项目](https://github.com/SawyerHood/draw-a-ui)，使用 [React](https://zh-hans.react.dev/learn) + [TLDraw](https://github.com/tldraw/tldraw) + [OpenAI](https://platform.openai.com/docs/api-reference/chat/create)（多模态 gpt-4-vision） 做了一款这样的工具案例； + +
+ +
+ +对于研发工程师来说，只是使用其实没多大意义，重要的是知道这东西是怎么实现的。那么接下来小傅哥就来详细给大家介绍下具体的设计实现过程。 + +>文末提供了该案例的课程地址（含源码）和项目的体验地址。体验地址：https://openai.itedus.cn/#/draw + +## 一、场景说明 + +本节小傅哥会带着大家先以最简单的方式完成 OpenAI 多模态接口与 TLDraw 的对接，再讲解项目中如何使用策略模式拆解不同类型的 OpenAI 服务接口（`文生文`、`文生图`、`多模态`）。 + +
+ +
+ +- 首先，我们知道 OpenAI 的多模态模型，是需要像接口中传一个 BASE64 图片信息，并给予对应的描述性 Prompt 脚本。这样 OpenAI 就会知道我们要基于对这个图片做什么。 +- 那么，我们就需要一款在线画图的工具，比如 [TLDraw](https://github.com/tldraw/tldraw) 或者 [Draw.io](https://github.com/jgraph/drawio) 把这样的绘图能力引入到 React 工程中。通过绘图后生成截图，再把图片转换为 BASE64 就可以使用。 +- 最后，把 OpenAI 传递回来的接口数据，用 React 进行展示和效果渲染。也就是操作完成后，你可以看到 HTML 对应的展示效果。 + +## 二、功能实现 + +### 1. 多模态接口 + +```java +curl -X POST "https://api.openai.com/v1/chat/completions" \ + -H "Content-Type: application/json" \ + -H "Authorization: Bearer sk-kgUPx1vKDywFbsun7c05Ed5eA4C24d4aA7B06aE9F76e6eFe" \ + -d '{ + "model": "gpt-4-vision-preview", + "max_tokens": 4096, + "messages": [ + { + "role": "system", + "content": "Your-System-Prompt-Here" + }, + { + "role": "user", + "content": [ + { + "type": "image_url", + "image_url": { + "url": "https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg" + } + }, + { + "text": "Turn this into a single html file using tailwind.", + "type": "text" + } + ] + } + ] + }' + +``` + +- 首先，我们做一个东西的时候，要先知道最根本调用是如何处理的。 +- 之后，多模态接口与以往的 gpt-3.5、gpt-4.0 都是用的同一个接口，`v1/chat/completions` 只是用了 `gpt-4-vision-preview` 模型。同时 content 既可以是单独的描述字符串，也可以是对象类型含有 `type`、`text`、`image_url` 的方式进行使用。 + +## 二、前端实现 + +本案例基于 React 构建的前端页面，如果你还是个前端小白可以学习此份教程；[https://zh-hans.react.dev/learn](https://zh-hans.react.dev/learn) —— 全中文官网资料非常适合入门。 + +### 1. 工程介绍 + +
+ +
+ +工程主要分为三块，OpenAI 接口、存储和工具类、TLDraw UI绘制页面 + 调用 OpenAI 接口的实现。 + +### 2. tldraw 组件 + +在开发前端代码的时候，需要按照 `npm install @tldraw/tldraw@2.0.0-alpha.17` 组件。 + +```react +// 引入组件 +const Tldraw = dynamic(async () => (await import('@tldraw/tldraw')).Tldraw, { + ssr: false, +}) + +// 使用组件 + +``` + +- 引入组件后就可以在 page.tsx 中使用这个组件了，目前你启动 react 会看到整个运行出来的 UI 设计页面。 + +### 3. 生成图片 + +```react +// tldraw 可以把当前页面转换为 svg 图片 +const svg = await editor.getSvg(Array.from(editor.currentPageShapeIds)) +// 基于工具把 svg 图片转换为 png图片 +const png = await svg2image(svg, { + type: 'png', + quality: 1, + scale: 1, +}) +// 再把png图片在前端直接转换为 base64 +const dataUrl = (await blobToBase64(png!)) as string +``` + +### 4. 调用接口 + +```react +try { + let json = await getResponseFromAPI(dataUrl, prompt) +} catch (error: any) { + console.log(error) + alert(`Error from open ai: ${JSON.stringify(error.message)}`) + return +} +``` + +- 之后就可以同步调用接口数据等待返回结果，回显到页面即可。 + +## 三、使用体验 + +### 1. 初始动作 + +```react +echo "BASE_API_URL=url-your-proxy like https://xxxxx.proxy.com/v1/chat/completions \r\nOPENAI_API_KEY=sk-your-key" > .env.local +rm -rf node_modules +npm install +npm run dev +``` + +- 推荐使用 WebStorm 打开 openai-tldraw 工程，它会自动的提示你执行 `npm install` 构建项目。 +- 当你进入 openai-tldraw 工程中，需要先执行 echo 教程，创建出 `.env.local` 文件。这个配置里写入你 BASE_API_URL 和 OPENAI_API_KEY +- 最后在工程中 package.json 点击 dev 左侧的绿色按钮或者执行 `npm run dev` 都会启动工程。 +- 启动后访问地址：[http://localhost:3000/](http://localhost:3000/) + +### 2. 生成效果 + +

+ +
+ +小傅哥，先举个这样登录的例子🌰，让大家熟悉下这个业务场景。 + +这是一个 CSDN 微信扫码登录的场景，通过 F12 打开浏览器的控制台，可以看到不断的请求一个网络地址，判断用户是否扫码。当你使用微信扫码后，则会登录成功跳转到网站的首页。 + +
+ +
+ +通过这样的一个页面效果展示，我们粗略的可以知道，用户页面不断的 checkScan 检测，是需要用到一个唯一ID值。而当用户用微信扫码后，这个唯一ID值则可以通过微信公众号获取到并保存，同时创建出唯一ID 和 Token 的映射关系。那么当 checkScan 扫描到服务端有这么一个映射，则可以把 Token 取回来存到浏览器中，让用户登录成功。 + +流程就是这样，那具体的代码实现是如何处理的呢？接下来小傅哥就给大家分享下，怎么来实现一下这个方案。 + +>文末提供了「星球：码农会锁」🧧优惠加入方式，以及本节课程的代码地址。项目演示地址：[https://gaga.plus](https://gaga.plus) + +## 一、流程设计 + +微信扫码登录的流程主要包括；用户、浏览器、后端服务、公众号，这四个部分。我们可以先通过UML流程图，了解下整个调用关系。 + +
+ +
+ +- 首先，由用户发起登录操作。让WEB页面从服务端获取登录凭证。 +- 之后，前端页面拿到登录凭证后，可以使用 Ticket 从公众号服务平台换取二维码。 +- 最后，用户扫码登录。扫码后，服务端会接收到来自公众号的回调消息，服务端再把回调消息中的 openid【用户唯一标识】和 ticket 进行绑定。这个时候你也可以创建出 jwt token 反馈给前端，作为登录成功的存储信息，后续校验 jwt token 就可以了。 + +有了这样一个流程的理解，接下来，我们就可以看下代码是如何实现的了。 + +## 二、对接文档 - 公众号平台 + +- 微信公众号测试平台：[https://mp.weixin.qq.com/debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index](https://mp.weixin.qq.com/debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index) - `不需要申请公众号即可完成测试，类似沙箱环境` +- 获取 Access Token 文档：[https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Get_access_token.html](https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Get_access_token.html) +- 生成带参数的二维码：[https://developers.weixin.qq.com/doc/offiaccount/Account_Management/Generating_a_Parametric_QR_Code.html](https://developers.weixin.qq.com/doc/offiaccount/Account_Management/Generating_a_Parametric_QR_Code.html) - `最终就是用户扫描的二维码` +- 内网穿透工具，[natapp.cn](https://natapp.cn/) - 因为需要让公众号调用到本地的服务，所需要把你的服务映射到公网上使用。注意；要选择付费的12元，否则不能对接。 + +## 三、功能实现 + +小傅哥这里采用了 DDD 的工程模型结构，开发公众号扫码登录服务端案例。如果你对 DDD 还不是太熟悉，可以看下小傅哥写的系列 DDD 教程；[《Java 简明教程》](https://bugstack.cn/md/road-map/road-map.html) + +### 1. 工程结构 + +

+ +- xfg-dev-tech-app 是启动应用程序的入口，其他模块也被直接或者间接的引入到 app 模块下，这样才能被 Spring 扫描加载。 +- xfg-dev-tech-infrastructure 是基础设施层，用于对接外部接口、缓存、数据库等相关内容的连接使用。本节主要是对接微信开发平台的接口。采用的是 retrofit2 技术框架，这样对接起来更加方便。 +- xfg-dev-tech-domain 是功能实现层，像是登录的具体实现，就是在 domain 领域层实现的。你将来使用 DDD 做的其他功能，也是放到 domain 领域下实现，每一个功能就是就是一个模块。 +- xfg-dev-tech-types 用于定义基本的类型、枚举、错误码等内容。 + +### 2. 二维码获取 + +从[微信官网文档](https://developers.weixin.qq.com/doc/offiaccount/Account_Management/Generating_a_Parametric_QR_Code.html)阅读可以知道，为了获取扫码登录的二维码，则需要3步； +1. 先获取 AccessToken，它是公众号的全局唯一接口调用凭据，公众号调用各接口时都需使用access_token。 +2. 通过 AccessToken 获取 ticket 凭证，凭证用于衔接用户扫码登录和公众号回调后获取凭证，以此关联用户登录信息。 +3. 通过 ticket 传递给前端，前端页面访问微信地址直接获取二维码。 + +#### 2.1 接口对接 - retrofit2 + +```java +public interface IWeixinApiService { + + /** + * 获取 Access token + * 文档：Get_access_token + * + * @param grantType 获取access_token填写client_credential + * @param appId 第三方用户唯一凭证 + * @param appSecret 第三方用户唯一凭证密钥，即appsecret + * @return 响应结果 + */ + @GET("cgi-bin/token") + Call getToken( + @Query("grant_type") String grantType, + @Query("appid") String appId, + @Query("secret") String appSecret + ); + + /** + * 获取凭据 ticket + * 文档：Generating_a_Parametric_QR_Code + * 前端根据凭证展示二维码 + * + * @param accessToken getToken 获取的 token 信息 + * @param weixinQrCodeRequestDTO 入参对象 + * @return 应答结果 + */ + @POST("cgi-bin/qrcode/create") + Call createQrCode(@Query("access_token") String accessToken, @Body WeixinQrCodeRequestDTO weixinQrCodeRequestDTO); + +} +``` + +- 使用 retrofit2 对接接口，它可以以一种面向对象的思维，使用 HTTP 接口，免去自己处理中间的对接过程。 +- 另外 okhttp3 框架对接接口也非常好用，有的时候可以配合一起使用。 + +```java +@Slf4j +@Configuration +public class Retrofit2Config { + + private static final String BASE_URL = "https://api.weixin.qq.com/"; + + @Bean + public Retrofit retrofit() { + return new Retrofit.Builder() + .baseUrl(BASE_URL) + .addConverterFactory(JacksonConverterFactory.create()) + .build(); + } + + @Bean + public IWeixinApiService weixinApiService(Retrofit retrofit) { + return retrofit.create(IWeixinApiService.class); + } + +} +``` + +- 使用 retrofit2 开发好接口后，在再 xfg-dev-tech-app 模块的 config 文件夹下，创建服务。【这有点像 MyBatis 的 Dao 接口一样，只需要定义好接口即可】 + +#### 2.2 ApiPost 请求 + +接口：`https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket=TICKET` + +

+ +http、rpc，属于即时性调用，立即反馈结果的场景。mq 用于异步驱动，流程解耦。而拼团组队的场景，组队是需要多人参与和支付的情形，只有统一完成拼团后，才能 mq 驱动后续流程。而不是一开始 http 请求就能立马拼团组队完成。 + +### 2. 为什么做了微服务的拆分，拆分的依据是什么？为什么拆分了微服务之后还要拆分领域？可不可以每个领域都作为一个微服务？ + +微服务的目的是划分大的系统边界，拆分原则可以包括；按业务功能拆分、按数据模型拆分、按团队结构拆分、按技术特性拆分、按变更频率拆分，但不要过度细化的拆分，避免造成分布式系统过度复杂性。 + +而对于拼团场景是一个独立的营销玩法，可以被拆分成一个独立的微服务。这样迭代、维护、上线，也都会更加轻量，也便于与其他平台对接。之后对于拼团内的服务模块，都以支撑拼团为主，符合最新当前的诉求进行设计。当然没有永远的适合，如果将来拼团变得更大，需要支撑的场景更多，也会考虑做模块的微服务拆分。 + +### 3. 优惠试算使用了多线程异步加载，为什么这里不用缓存？ + +试算加载的是当前用户行为的最新数据，而缓存则不适用于此场景。当然如果试算中有一些不频繁变化的偏固定的配置类数据，则可以通过缓存处理。另外，在公司（美团、京东、字节、滴滴等）拼团场景则更为复杂，试算时候需要的数据量更多，多线程则会更体现出必要性。 + +### 4. 平台在高并发下的扣减库存和防止超卖是怎么做的？ + +这一块的库存扣减使用的是无锁化设计，setnx 兜底。但如果是加分布式锁，则会出现排队问题，达不到最大并发的效果。而因库存使用了 redis 计数 + 锁，以及添加了幂等恢复量，所以不会有超卖问题。 + +### 1. 项目设计与架构 + +1. **为什么选择DDD领域驱动设计？如何划分领域边界？** + **答**：DDD能有效解决复杂业务逻辑的拆解问题，通过四色建模和业务场景分析，划分出活动域（管理拼团规则）、标签域（用户画像和权限过滤）、交易域（订单和结算）。例如，拼团锁单流程属于交易域，而人群标签过滤属于标签域。 +2. **微服务间如何通信？如何保证数据一致性？** + **答**：对内外对接系统，分别采用HTTP（Feign/RestTemplate）和 MQ（RabbitMQ）方案。关键链路（如订单结算）通过MQ保证最终一致性，结合本地事务表+补偿任务（如定时检查未完成的结算请求）。 +3. **六边形架构如何落地？解决了什么问题？** + **答**：通过适配器层隔离核心业务与外部依赖（如数据库、Redis）。例如，订单结算的核心逻辑独立于HTTP回调或MQ监听的具体实现，提升核心代码的稳定性和可测试性。 + +> DDD 是一个亮点，中大厂公司都在推进 DDD 的项目重构。站在技术角度，这样的架构更好维护。站在领导角度，这样的拆分可以更好了解系统设计便于制订KPI。同时有清晰的业务领域划分，AI 开发工具可以更好的结合进来。[招聘里DDD的体现，jump 🏃🏻](https://bugstack.cn/md/zsxq/memorabilia/job-hire-jd.html) + +### 2. 核心技术实现 + +1. **Redis在项目中如何应用？举例说明** + **答**：1）BitMap存储用户标签（如是否参与过某活动）；2）分布式锁控制拼团组队结算触达并发；3）缓存活动配置（如有效期、折扣规则），降低数据库压力。 + +2. **责任链模式如何解耦复杂流程？举例说明** + **答**：拼团锁单流程拆解为多个处理器链：活动状态校验→用户资格校验→库存检查。每个处理器独立实现，通过工厂模式动态组装，避免if-else嵌套。 + +3. **异步线程如何优化性能？如何管理线程池？** + **答**：将营销数据加载从串行改为并行（如使用CompletableFuture）。通过动态线程池监控任务队列和拒绝策略，结合普罗米修斯采集指标，避免线程池耗尽。`注意多准备下多线程、线程池的八股` + +### 3. 核心业务场景 + +1. **拼团结算的HTTP和MQ双重回调如何设计？如何保证可靠性？** + **答**：1）结算后同时发送HTTP请求和MQ消息；2）异步线程池处理回调，失败后进入重试队列；3）定时任务补偿未完成回调，配合分布式锁避免重复执行。 +2. **人群标签如何通过BitMap实现？举例说明** + **答**：例如，用户ID哈希后映射到BitMap的某一位。运营配置“仅限新用户”的活动时，Job任务扫描历史订单，将老用户对应位标记为0，查询时通过`BITCOUNT`判断资格。 +3. **策略模式在折扣计算中的应用？如何扩展新策略？** + **答**：定义接口`DiscountStrategy`，实现类 `MJCalculateService`（满减）、`NCalculateService`（N元购）、`ZJCalculateService`（直减）、`ZKCalculateService`（折扣）。新增策略时只需添加实现类并注册到Spring上下文，通过策略工厂按类型调用。 + +### 4. 高并发与容错（这部分会在第3阶段加入） + +1. **如何解决库存超卖问题？** + **答**：1）Redis原子操作（DECR）预扣库存；2）数据库最终扣减时加乐观锁；3）异步补偿任务回滚异常订单。 +2. **分布式锁的实现方案？遇到过哪些坑？** + **答**：基于Redis的Redisson（看门狗机制续期）。注意点：1）锁粒度细化（按活动ID+商品ID）；2）避免锁过期后业务未执行完，需结合版本号校验。 +3. **如何设计熔断降级策略？** + **答**：Sentinel监控外部服务（如支付接口）的异常比例，超阈值时熔断，降级为返回默认错误码或缓存数据，并记录日志供补偿任务处理。 + +### 5. 监控与运维（这部分会在第3阶段加入） + +如配置说明接入普罗米修斯监控，同时也可以使用 arthas、dump mat。地址：[https://bugstack.cn/md/road-map/grafana.html](https://bugstack.cn/md/road-map/grafana.html) + +1. **普罗米修斯监控哪些指标？如何定位性能瓶颈？** + **答**：监控接口TP99、线程池活跃度、Redis命中率、MQ堆积量。通过Grafana仪表盘分析慢SQL（MyBatis拦截器采集）或高耗时责任链节点。 +2. **动态配置中心如何实现？如何保证实时性？** + **答**：基于Nacos/Zookeeper，配置变更时通过Spring Cloud Bus通知服务。关键配置（如活动开关）结合本地缓存，通过@RefreshScope实时生效。 +3. **Docker化部署的优化经验？** + **答**：1）多阶段构建减小镜像体积；2）JVM参数调优（-Xmx限制内存）；3）健康检查接口 skywalking、artash 探针结合，实现系统监控。 + +### 6. 设计模式与代码规范 + +1. **规则树模式如何实现？举例说明** + **答**：根节点为入口，子节点为具体规则（如切量、标签过滤）。每个节点实现`RuleNode`接口，通过组合模式构建树形结构，支持动态扩展节点。 +2. **如何避免策略模式带来的类膨胀问题？** + **答**：1）将策略实现类定义为无状态Bean，复用实例；2）通过注解+自动扫描注册策略；3）策略参数化配置，减少重复代码。 +3. **AOP在项目中的典型应用场景？** + **答**：1）DCC 动态配置中心；2）@LogTrack 记录核心链路日志（切面加日志，可以让 DeepSeek 写个案例）； + +### 7. 扩展性与业务，你怎么设计新功能？ + +1. **如何支持多种拼团类型（如老带新、阶梯团）？** + **答**：抽象拼团模板（Template Pattern），定义成团条件接口（如人数满额、金额达标）。新增类型时实现接口，并通过工厂模式注入。 +2. **如何设计活动预热机制？** + **答**：1）活动开始前定时任务加载配置到Redis；2）缓存热门活动的商品信息；3）通过压测工具预热JVM和线程池。 +3. **如何实现灰度发布？** + **答**：1）Apollo配置中心按用户ID百分比切流；2）网关层根据请求头路由到新老服务；3）结合Prometheus监控异常，快速回滚。 + +### 8. 综合问题 + +1. **项目中最大的挑战是什么？如何解决？** + **答**：高并发下Redis雪崩。解决方案：1）缓存分层（本地缓存+Redis）；2）热点数据预加载；3）随机过期时间。 +2. **如果让你重构系统，会优化哪些点？** + **答**：1）引入分库分表解决订单表膨胀；2）增加AI + RAG + MCP 提供智能分析和运营服务；3）使用Guava本地缓存，管理复杂数据结构。 +3. **如何向非技术人员解释系统设计？** + **答**：类比“组队购物”，系统像智能管家：1）自动匹配规则（如折扣）；2）确保组队不超时；3）失败时自动重试，保证最终成功。 + +### 9. 人群标签 + +人群标签这一部分该怎么回答？ + +在互联网公司里，量化数据分析师（经营分析）会把各类系统工程的数据采集到统一大数据集群，之后通过 Python、R 语言，建一个数据模型的方式跑数。比如 xxx 类人群，购物喜好、收藏喜好、用券喜好、高频下单、回购，以及从第三方获取的数据（键盘输入）、浏览器帖子等。根据这些数据定义一个量化模型，做一个跑数作业，之后这些数据，可以写成人群标签。标签为bitmap（小型只要判断不存在的），以及直接记录用户id到redis的，更准确的判断人是否存在。之后研发引入数据包到系统中（也就是 redis 对接）之后使用。 + +>关于系统面试问题，涉及到的监控、数据、指标类，最好使用云服务部署上线 + 普罗米修斯监控完成压测和优化。 diff --git a/docs/md/project/group-buy-market/promotion/group-buy-market-v1.md b/docs/md/project/group-buy-market/promotion/group-buy-market-v1.md new file mode 100644 index 000000000..7164dcd4b --- /dev/null +++ b/docs/md/project/group-buy-market/promotion/group-buy-market-v1.md @@ -0,0 +1,93 @@ +--- +title: 新"拼多多"系项目，编码3千行，进度35%，设计模式拉满！ +lock: no +--- + +# 新"拼多多"系项目，编码3千行，进度35%，设计模式拉满！ + +作者：小傅哥 +

博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是小傅哥。 + +近几周在做公司的一个项目重构，有多复杂呢！`整个工程近40万行代码`，`重构部分单个类超过3000行`。历史最长周期的代码有`快10年以上`。而这东西到我手了，再继续这么写，早晚搞出事故！**所以，我决定改变一下。** + +
+ +
+ +**你不可能停了业务需求再重构！** + +在互联网公司中，产品需求交付永远是第1位的，他们不关心你代码是怎么实现的。但不要出问题，出了问题就是你的问题。 + +而长期需求迭代经历数年的代码，早已腐化的非常严重。但重构又绝对是非常考验工程师的业务经验和技术能力的。**往往重构不佳，就从维护一份屎山，到维护两份啦！** + +但好在，我的工程落地经验积累较多，通过巧妙的设计模式运用，能从复杂的流程中划分出边界结构，从而降低业务功能的理解难度。与此同时，为了让其他的伙伴在不是特别能熟练使用设计模式的情况下，我把设计模式常用的模型结构，独立成一个单独的组件包，主要引入就可以按照这样的结构来开发代码。从一定程度上，让大家的代码都能在不错的水平上。 + +>如果，你也想提高自己的代码能力和工程驾驭能力，那么可以跟着小傅哥一起学习下。 + +## 一、实践出真知 + +编程这东西，最好的学习方式就是实践。拿一个真实项目，结合实际的需求，上手操作一遍，小白也能扎扎实实的学习到实际的技术运用。 + +所以，小傅哥为了让大家能学习到，关于工程中运用设计模式，解决实际场景的重构问题。专门提供了一个新的项目，在项目中解耦出标准的通用设计模型结构，再到需求中运用处理实际问题。 + +这个项目就是小傅哥的技术社群，星球「码农会锁」，最新的第14个项目《拼团交易平台系统》，结合实际场景设计和落地的设计模式方案。—— 这个项目，会给你设计模式更牛的认知，妥妥的让你可以在自己的项目使用上设计模式！ + +
+ +
+ +`拼多多`、`京东`、`腾讯`，都有很多这样的拼团场景，之所以选择这样的业务需求，就是让大家可以结合实际的项目来学习真实的技术。**这套项目目前已经进行了13节，全程视频+小册，手把手带着设计和编码。** + +>接下来，我们就看看，小傅哥是怎么带着大家玩转设计模式的！ + +## 二、提炼通用模型 + +`条条大路通罗马，但放到项目工程中，就有点受不了了！` + +咋回事呢？🤔 + +只要不加规范，同样是做规则树、责任链、策略模式，都能有非常多的方式。那么，每来一个新人，就可能再多出来一份新的设计方式。这些一类的但非常差异化的东西，在下一个人要迭代需求的时候，就会有非常多的地方，有不同的改法。可能想死的新都有。 + +所以，为了把这些东西规范化，小傅哥设计了一套模型模板，单独提炼于项目需求逻辑之外。所有，有需要使用的场景，都可以引入使用。大家都在一个标准下使用设计模式，维护、迭代、扩展，也都非常容易。 + +
+ +
+ +- 首先，随着拼团项目的开发，定义2套了标准的通用设计模式结构。2种模式的责任链和1套规则树。这套责任链还用到了大家常学的数据结构中的链表设计和实现。 +- 之后，这套模型非常巧妙的运用到业务场景中。举例像是规则树，还提供了多线程数据异步加载，自由化功能逻辑编排。这样的设计模式，可以解决非常多的场景问题。 + +> 为了更好的理解这样的模型运行，接下来，小傅哥甩个图给大家感受下！—— 小傅哥，画图可牛了，见图就知意。 + +## 三、小图很美！💐 + +如图，是拼团的部分流程。营销类场景的系统都是很复杂的，它的流程节点非常多，也经常做扩展和调整。所以要做非常细腻的设计，满足复杂流程的实现。 + +
+ +
+ +- 以上这两部分流程分别包括试算和锁定优惠，这里会使用到规则树和责任链进行实现。 +- 下面，就介绍下关于规则树和责任链的设计和使用。 + +### 1. 规则树 + +`千万别觉得设计模式没有用`，否则也不会那么多源码框架中，会有那么多设计模式使用。MyBatis 一个框架，都用了10种设计模式！ + +像是这些设计模式，合理的设计好，是真的可以解决非常复杂的业务流程编码，让代码变得优雅。既不会有那么多的 if···else，也不会让代码逻辑成片的堆到一个类中。 + +
+ +
+ +- 如图，这是一个规则树模型，解决的拼团中实际的场景业务。从根节点、开关节点、营销节点、人群节点，再到最终的正常和异常结束节点。每个节点分别处理自己的业务流程。 +- 你可以想象，如果没有这样的设计模式模型结构，那么在代码中，就是一个大方法中，一堆的逻辑编写，维护的成本是非常高的。 + +**展示一段代码，让兄弟👬🏻看看这是啥样的！** + +```java +@Slf4j +@Service +public class MarketNode extends AbstractGroupBuyMarketSupport { + + @Resource + private ThreadPoolExecutor threadPoolExecutor; + /** + * Spring 注入详细说明 + */ + @Resource + private Map discountCalculateServiceMap; + @Resource + private ErrorNode errorNode; + @Resource + private TagNode tagNode; + + @Override + protected void multiThread(MarketProductEntity requestParameter, DefaultActivityStrategyFactory.DynamicContext dynamicContext) throws ExecutionException, InterruptedException, TimeoutException { + // 异步查询活动配置 + QueryGroupBuyActivityDiscountVOThreadTask queryGroupBuyActivityDiscountVOThreadTask = new QueryGroupBuyActivityDiscountVOThreadTask(requestParameter.getActivityId(), requestParameter.getSource(), requestParameter.getChannel(), requestParameter.getGoodsId(), repository); + FutureTask groupBuyActivityDiscountVOFutureTask = new FutureTask<>(queryGroupBuyActivityDiscountVOThreadTask); + threadPoolExecutor.execute(groupBuyActivityDiscountVOFutureTask); + + // 异步查询商品信息 - 在实际生产中，商品有同步库或者调用接口查询。这里暂时使用DB方式查询。 + QuerySkuVOFromDBThreadTask querySkuVOFromDBThreadTask = new QuerySkuVOFromDBThreadTask(requestParameter.getGoodsId(), repository); + FutureTask skuVOFutureTask = new FutureTask<>(querySkuVOFromDBThreadTask); + threadPoolExecutor.execute(skuVOFutureTask); + + // 写入上下文 - 对于一些复杂场景，获取数据的操作，有时候会在下N个节点获取，这样前置查询数据，可以提高接口响应效率 + dynamicContext.setGroupBuyActivityDiscountVO(groupBuyActivityDiscountVOFutureTask.get(timeout, TimeUnit.MINUTES)); + dynamicContext.setSkuVO(skuVOFutureTask.get(timeout, TimeUnit.MINUTES)); + + log.info("拼团商品查询试算服务-MarketNode userId:{} 异步线程加载数据「GroupBuyActivityDiscountVO、SkuVO」完成", requestParameter.getUserId()); + } + + @Override + public TrialBalanceEntity doApply(MarketProductEntity requestParameter, DefaultActivityStrategyFactory.DynamicContext dynamicContext) throws Exception { + log.info("拼团商品查询试算服务-MarketNode userId:{} requestParameter:{}", requestParameter.getUserId(), JSON.toJSONString(requestParameter)); + + // 获取上下文数据 + GroupBuyActivityDiscountVO groupBuyActivityDiscountVO = dynamicContext.getGroupBuyActivityDiscountVO(); + if (null == groupBuyActivityDiscountVO) { + return router(requestParameter, dynamicContext); + } + + GroupBuyActivityDiscountVO.GroupBuyDiscount groupBuyDiscount = groupBuyActivityDiscountVO.getGroupBuyDiscount(); + SkuVO skuVO = dynamicContext.getSkuVO(); + if (null == groupBuyDiscount || null == skuVO) { + return router(requestParameter, dynamicContext); + } + + // 优惠试算 + IDiscountCalculateService discountCalculateService = discountCalculateServiceMap.get(groupBuyDiscount.getMarketPlan()); + if (null == discountCalculateService) { + log.info("不存在{}类型的折扣计算服务，支持类型为:{}", groupBuyDiscount.getMarketPlan(), JSON.toJSONString(discountCalculateServiceMap.keySet())); + throw new AppException(ResponseCode.E0001.getCode(), ResponseCode.E0001.getInfo()); + } + + // 折扣价格 + BigDecimal deductionPrice = discountCalculateService.calculate(requestParameter.getUserId(), skuVO.getOriginalPrice(), groupBuyDiscount); + dynamicContext.setDeductionPrice(deductionPrice); + + return router(requestParameter, dynamicContext); + } + + @Override + public StrategyHandler get(MarketProductEntity requestParameter, DefaultActivityStrategyFactory.DynamicContext dynamicContext) throws Exception { + // 不存在配置的拼团活动，走异常节点 + if (null == dynamicContext.getGroupBuyActivityDiscountVO() || null == dynamicContext.getSkuVO() || null == dynamicContext.getDeductionPrice()) { + return errorNode; + } + + return tagNode; + } + +} +``` + +这是其中的一个营销节点，处理拼团营销试算的过程； + +1. multiThread 负责异步多线程方式加载数据，节省数据获取时间。 +2. doApply 处理业务流程，最后用 router 路由到下一个节点。 +3. get 是获取到下一个节点，是走到哪里由这块判断。 + +
+ +
+ +> 这套结构模型可以解决非常多的业务场景，而且每一个类都可以非常清晰的表达出具体的业务逻辑。无论以后是维护代码、迭代需求还是排查线上问题都变得很容易。 + +### 2. 责任链 + +规则树与责任链相比，规则树会有很多分叉流程，但责任链比较轻量主要负责单链路流程，在编码过程中不需要考虑流程的流转。相对来说更轻量了。 + +这里小傅哥设计了2套责任链模型，model1 - 单例链、model2 - 多例链（动态组装多套）。如图； + +
+ +
+ +- 如图，ILink 使用了数据结构责任链模型，ILogicHandler 为处理具体的业务功能逻辑。这里巧妙的设计在于把链的管理和业务逻辑的受理进行拆分，之后再由 LinkArmory 进行链路装配。**「当你看到代码的时候会觉得这真爽！原来写代码可以这样有意思」** +- 因为 LinkedList 实现如链表一样的方法，有添加，也有摘除链，所以还可以根据数据库配置动态处理链的实例化。 + +```java +@Service +public class Rule02TradeRuleFactory { + + @Bean("demo01") + public BusinessLinkedList demo01(RuleLogic201 ruleLogic201, RuleLogic202 ruleLogic202) { + + LinkArmory linkArmory = new LinkArmory<>("demo01", ruleLogic201, ruleLogic202); + + return linkArmory.getLogicLink(); + } + + @Bean("demo02") + public BusinessLinkedList demo02(RuleLogic202 ruleLogic202) { + + LinkArmory linkArmory = new LinkArmory<>("demo02", ruleLogic202); + + return linkArmory.getLogicLink(); + } + + @Data + @Builder + @AllArgsConstructor + @NoArgsConstructor + public static class DynamicContext { + private String age; + } + +} +``` + +- 之后就可以动态的使用这套责任链完成功能需求的处理。demo01、demo02，分别组装了自己的责任链。 + +> 以上，在小傅哥的全部项目中也只是冰山一角，如果你加入小傅哥的社群学习，我还会让你感受到更多的关于工程在实际场景下设计的魅力！ + +## 四、一套学习进阶路线图！ + +**10年互联网大厂的经历，得出**；`最快的成长方式，是不要重复做一件事，而是能成体系的，有阶段性的成长。` + +为此小傅哥做了一整套的实战学习进阶项目，从小白到大佬，全程视频手把手带着从0到1，一步步完成项目的设计、开发和上线。在整套内容学习过程中，小傅哥为你提供了非常好的技术交流社群，及时解决学习问题。还包括调试你的问题代码，带你快速🔜出坑！ + +

+ +**我能哪些方面使用 Ai 提效呢？** + +在互联网程，序员工程开发方面，关于 Ai 提效最为常见的，也是市面上使用最多的，就是各类的 Ai 编码软件。如 cursor、trae.ai、IntelliJ IDEA 中的各类 Ai 插件，都可以辅助我们完成项目的编码操作。甚至一些简单的 HTML 页面，几乎在刚开始开发阶段，可以快速搭建起来，确实非常提效。 + +不过这些都是固定的软件，他们并没有深度结合到业务场景中，从整个研发的生命周期看，还有非常多的节点可以被 Ai 提效。如；需求评审、研发设计、系统发布、代码评审、单测用例、业务监控、问题排查&故障分析等。都可以深入自身的业务，运用 Ai 开发进行提效。 + +这里尤其是问题排查和故障分析，在互联网企业中，尤其是大厂的业务，几乎每天都要配和运营的反馈的客诉，系统的报警日志，性能的降低反馈，进行人工检索`系统监控`、`日志`、`分析`，这部分要投入大量的人工成本，虽然可能系统并不是真的有问题，但也要一遍遍的排查这些问题。 + +所以，结合这样的场景，小傅哥在带着大家的实战项目，也逐步的引出关于 Ai 在应用项目上的提效处理。今天分享的一个场景就是基于 Ai MCP 分析系统的 ELK 日志。后面还会分析关于监控、数据库一起分析。 + +>🧧 文末提供了小傅哥技术社群全套的17个应用实战项目，一次加入可以获得全部的文档、源码、视频，嘎嘎提高能力！ + +## 一、系统说明 + +小傅哥带着社群伙伴，做了一套 **《拼团交易平台系统》**，因为拼团是非常重要的 toc 业务场景，也是拼多多、腾讯、京东等服务平台，交易支付时候，最为常见的一种营销手段。它可以通过用户自传播方式增强交易量，也是拼多多最开始起家形成巨大规模的一个业务逻辑。 + +该系统采用了 DDD 领域驱动设计进行建模，拆分领域模块边界，形成；活动领域、人群领域、交易领域，来构建拼团营销交易流程，达到试算、锁单、结算等步骤流程。这个过程中提炼了通用设计模式，规则树、责任链，可以非常有效的统一的治理流程编排实现。 + +
+ +
+ +
+ +
+ +如图，是两套微服务的对接链路。 + +- 首先，在小型支付商城，创建订单的过程中，调用拼团营销锁单。这个时候就拿到了当笔订单的优惠金额。之后创建支付订单唤起收银台，之后用户就可以按照最终的优惠金额进行支付了。 +- 之后，在支付完成后，收到回调消息，进行营销拼团进度结算。直至拼团组队进度完成，在回调给支付商城，触达交易结算。 + +这样一整套完整的交易营销流程，是非常真实的实际场景对接处理方案。尤其是营销场景下的复杂的试算、规则的过滤，再到结算的处理，都是使用了非常巧妙的编码操作，使用了非常好的设计模式进行设计。这块非常有的学！ + +## 二、配置日志 + +### 1. 系统部署（ELK） + +
+ +
+ +- 基于 Docker 部署 ELK 系统，采集上报日志。 + +### 2. 上报配置 + +```java + + + + + + + ${LOG_STASH_HOST}:4560 + + + + + + + + + + + + +``` + +- 通过增加 LogstashTcpSocketAppender 上报系统日志到 ELK。 + +### 3. 生产日志 + +开始下面的操作之前，需要启动 SpringBoot 服务，访问接口，让系统产生一些运行日志。 + +
+ +
+ +```java +25-06-08.08:05:08.441 [http-nio-8091-exec-2] INFO ZJCalculateService -b601d8d5-ff62-4adb-8260-16d8b6af53ef 优惠策略折扣计算:0 +25-06-08.08:05:08.445 [http-nio-8091-exec-2] INFO EndNode -b601d8d5-ff62-4adb-8260-16d8b6af53ef 拼团商品查询试算服务-EndNode userId:xfg04 requestParameter:{"channel":"c01","goodsId":"9890001","source":"s01","userId":"xfg04"} +25-06-08.08:05:08.451 [http-nio-8091-exec-2] INFO MarketIndexController -b601d8d5-ff62-4adb-8260-16d8b6af53ef 查询拼团营销配置完成:xfg04 goodsId:9890001 response:{"code":"0000","data":{"activityId":100123,"goods":{"deductionPrice":20.00,"goodsId":"9890001","originalPrice":100.00,"payPrice":80.00},"teamList":[],"teamStatistic":{"allTeamCompleteCount":0,"allTeamCount":2,"allTeamUserCount":4}},"info":"成功"} +``` + +- 访问的是拼团试算接口，产生一些数据运行日志。在这个过程中，会多次访问系统，触发拼团接口的限流操作。多一些日志也能更好的让 Ai MCP 进行分析。 + +### 4. 查看日志 + +
+ +
+ +- 配置文章后，访问 Kibana 数据可视化后台，这会你可以看到上报上来的日志信息。 +- 到这里，日志配置完成。接下来，我们就可以就 Ai MCP，来访问日志了。 + +## 三、日志分析 + +AI MCP 是小傅哥社群内的另外一套项目，[《DeepSeek RAG、MCP、Agent》](https://t.zsxq.com/GwNZp) 智能体，课程。课程里有讲解如何开发和使用 MCP 服务，以及构建 Agent 智能体。地址：[https://t.zsxq.com/GwNZp](https://t.zsxq.com/GwNZp) - `感兴趣的伙伴可以进入学习` + +这里小傅哥选择一个 ElasticSearch MCP 服务，对接到咱们的 ELK 日志上，通过对接的 MCP 服务帮我们检索日志。 + +### 1. 环境说明 + +- AI 对话客户端；https://claude.ai/download - 不非得使用这个客户端。像是 trae.ai、cursor 等，能配置 mcp 服务的都可以的。 +- 发码平台：https://sms-activate.io/ - `claude.ai 注册需要使用` +- node 环境，需要 v18+ https://nodejs.org/en/download +- mcp 服务01；https://github.com/modelcontextprotocol/servers/tree/main/src/filesystem +- mcp 服务02；https://github.com/elastic/mcp-server-elasticsearch + +### 2. 客户端使用 + +#### 2.1 配置文件 + +
+ +
+ +```java +{ + "mcpServers": { + "elasticsearch-mcp-server": { + "command": "npx", + "args": [ + "-y", + "@elastic/mcp-server-elasticsearch" + ], + "env": { + "ES_URL": "http://127.0.0.1:9200", + "ES_API_KEY": "your-api-key" + } + }, + "filesystem": { + "command": "npx", + "args": [ + "-y", + "@modelcontextprotocol/server-filesystem", + "/Users/fuzhengwei/Desktop" + ] + } + } +} +``` + +- 配置后要重启客户端。注意 `/Users/fuzhengwei/Desktop` 更换为你的文件夹。 + +#### 2.2 对话提问 + +
+ +
+ +
+ +
+ +- 对话提问：`获取所有限流用户，并在 /Users/fuzhengwei/Desktop 创建限流文件写入用户。` +- 这样他就可以通过 ES 查询我们产生的日志数据，并给出分析报告。 + +#### 2.3 日志文件 + +
+ +
+ +- 打开产生的日志文件，可以把限流的用户拉取出来。方便我们分析提供问题。 + +### 3. 代码调用 + +这部分涉及到星球的 AI Agent 项目，工程地址：[https://gitcode.net/KnowledgePlanet/ai-agent-station-study](https://gitcode.net/KnowledgePlanet/ai-agent-station-study) + +#### 3.1 直接调用 + +```java +package cn.bugstack.ai.test.spring.ai; + +@Slf4j +@RunWith(SpringRunner.class) +@SpringBootTest +public class AiAgentMCPESTest { + + private ChatModel chatModel; + + private ChatClient chatClient; + + @Resource + private PgVectorStore vectorStore; + + public static final String CHAT_MEMORY_CONVERSATION_ID_KEY = "chat_memory_conversation_id"; + public static final String CHAT_MEMORY_RETRIEVE_SIZE_KEY = "chat_memory_response_size"; + + @Before + public void init() { + + OpenAiApi openAiApi = OpenAiApi.builder() + .baseUrl("https://apis.itedus.cn") + .apiKey("sk-vo81adWzUz1G0LBQ1cF1B804A1E04aC*****可申请") + .completionsPath("v1/chat/completions") + .embeddingsPath("v1/embeddings") + .build(); + + chatModel = OpenAiChatModel.builder() + .openAiApi(openAiApi) + .defaultOptions(OpenAiChatOptions.builder() + .model("gpt-4.1-mini") + .toolCallbacks(new SyncMcpToolCallbackProvider(stdioMcpClientElasticsearch()).getToolCallbacks()) + .build()) + .build(); + } + + @Test + public void test_chat_model_call() { + Prompt prompt = Prompt.builder() + .messages(new UserMessage( + """ + 有哪些工具可以使用 + """)) + .build(); + + ChatResponse chatResponse = chatModel.call(prompt); + + log.info("测试结果(call):{}", JSON.toJSONString(chatResponse)); + } + + @Test + public void test_chat_model_call_es() { + Prompt prompt = Prompt.builder() + .messages(new UserMessage( + """ + 查询xfg01日志，DSL 语句； + { + `index`: `springboot-logstash-2025.06.07`, + `queryBody`: { + `size`: 10, + `sort`: [ + { + `@timestamp`: { + `order`: `desc` + } + } + ], + `query`: { + `match`: { + `message`: `xfg01` + } + } + } + } + """)) + .build(); + + ChatResponse chatResponse = chatModel.call(prompt); + + log.info("测试结果(call):{}", JSON.toJSONString(chatResponse)); + } + + /** + * https://sai.baidu.com/server/Elasticsearch%2520MCP%2520Server/awesimon?id=02d6b7e9091355b91fed045b9c80dede + * https://github.com/elastic/mcp-server-elasticsearch + */ + public McpSyncClient stdioMcpClientElasticsearch() { + + Map env = new HashMap<>(); + env.put("ES_URL","http://127.0.0.1:9200"); + env.put("ES_API_KEY","none"); + + var stdioParams = ServerParameters.builder("npx") + .args("-y", "@elastic/mcp-server-elasticsearch") + .env(env) + .build(); + + var mcpClient = McpClient.sync(new StdioClientTransport(stdioParams)) + .requestTimeout(Duration.ofSeconds(100)).build(); + + var init = mcpClient.initialize(); + + System.out.println("Stdio MCP Initialized: " + init); + + return mcpClient; + + } + +} +``` + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +经过小傅哥这么多年的努力，👨🏻‍💻认认真真的做编程项目之下，一点点把来自于互联网真实技术教给社群伙伴。现在也是行了起来。在大学里`优秀毕业生分享上`，也能被伙伴认可，拿出来写到黑板上啦！ + +
+ +
+ +**他们是这么评价小傅哥的！** + +小傅哥在大型互联网，`toc业务场景，工作这么多年`，也确实积累了丰富的业务+技术经验。也深知，对于一个从事此行业的编程人员，应该学习哪些项目才能快速成长。 + +
+ +
+ +为此，小傅哥做了一整套项目，`由浅入深，循序渐进`。以不同难度级别的项目，带着小伙伴们稳扎稳打的成长。有了这样的真实场景学习，`既可以`提高自己的编程思维和编码能力，`又能`在面试中讲解出各种场景方案，`还能`为以后入职进入到公司快速融入团队。可以说是，一举多得。 + +> 🧧 文末提供了全套的实战项目，含有；业务项目、组件项目、创新AI项目，各项目对应的文档、视频、代码，全部提供给大家学习使用。 + +## 一、项目介绍 + +**于24年末，小傅哥以线上真实toc业务场景**，设计了一套 **《拼团交易平台系统》**，帮助大家深入学习，`前后端技术`、`分布式架构`、`微服务对接`、`Dev-Ops 发布上线`、`AI MCP + ELK + 普罗米修斯监控`、通用组件扳手工程设计等。可以说学习这样一套项目，就能完整的积累各项互联网toc场景常见方案和通用技术。 + +像是这样的项目，基本大家在使用各个互联网app的时候，都能体会到拼团的应用。如；`美团拼单`、`滴滴拼券`、`京东/拼多多购物`、`腾讯`等，都可以看到。所以这也是面试中面试官非常喜欢聊的业务和实现方案。 + +
+ +
+ +现在这套项目已经讲解了38节课程，所有的拼团正向流程 + 分布式方案 + Dev-Ops 部署和监控，都已完成。接下来将开启逆向退单流程。也就是7月5日，周末开启。 + +## 二、业务流程 + +如图，以用户旅途视角来看整个拼团流程。 + +
+ +
+ +- 如图，以上为用户旅途视角的全流程。从运营配置拼团活动，到用户从「小型支付商城（对接的一个场景）」，开始查看带有拼团优惠的上，进行试算，过滤规则。再到参与拼团，完成下单和一系列的流程处理。之后是拼团对于支付收单的入账计算，达成拼团目标后，回调（HTTP/MQ）商城服务，完成整个交易过程。 +- 之后，我们要考虑的是如何处理逆向流程，也就是退单的过程。退单分为当前过程中，拼团是否完成，未完成则根据是否支付了，取消锁单量和完成量。如果拼团已完成，则取消锁单量和完成量，拼团优惠释放后，则回调商城（refundGroupBuySuccess）,完成退单退货服务。 +- 一般，对于已经完成拼团的，有用户退单是不会对其他用户已经完成交易的进行退单的，会造成很差的体验。这部分成本往往由商家和平台分摊，毕竟平台的目的是为了卖货。 + +## 三、详细设计 + +### 1. 服务对接 + +
+ +
+ +### 2. 正向流程 + +
+ +
+ +### 3. 逆向流程 + +

视频：[https://t.zsxq.com/1VRZq](https://t.zsxq.com/1VRZq) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +今天是我们《拼团交易平台系统》项目学习的第1节，我们先从需求分析开始理解这样一个项目要做什么，要解决什么场景问题。同时也要知道研发是怎么承接的产品需求。 + +在互联网公司中，一个需求首先是从业务侧发起的盈利目标，拆分为不同的运营策略。再把对应的策略由产品经理设计为可以支撑市场运营操作完成盈利目标的具体项目。所以这里有一般有3个角色，包括；业务人员、运营人员、产品经理。他们分别在自己的岗位产生不同的资料，包括；MRD、BRD、PRD。 + +- 市场需求文档（MRD）： MRD是从市场的角度出发，描述目标市场的需求和机会。它通常包括目标客户群、市场趋势、竞争分析、市场机会、产品定位以及产品应该实现的市场目标等。MRD通常由产品经理或市场分析师编写，目的是定义产品应该解决的市场问题和满足的用户需求。 +- 业务需求文档（BRD）： BRD更侧重于业务角度，描述业务目标、业务流程、业务规则、业务问题以及业务需求。它是从组织的业务视角来定义需求，包括业务背景、业务目标、影响分析、风险评估等。BRD通常由业务分析师编写，目的是确保项目解决了正确的业务问题，并与公司的业务战略保持一致。 +- 产品需求文档（PRD）： PRD是更详细的文档，它根据MRD和BRD中确定的需求，具体描述产品的功能性和非功能性需求。PRD包括用户故事、用例、功能列表、性能要求、界面设计、用户体验等。PRD通常由产品经理编写，目的是为设计团队和开发团队提供一个明确的、详细的产品实现指南。 + +而研发最终看到的就是这份 PRD 文档，根据产品对 PRD 文档与各个负责的业务线研发进行的评审，让研发了解本次项目所需完成的工作。之后研发在会后根据 PRD 文档进行详细的设计和系统建模。这一部分前期的工作几乎占据了整个项目周期的50%以上的时间。所以研发写代码，只是众多环节中的一环。 + +接下来，我们来对本次的《拼团交易平台系统》进行需求分析，让大家细致的了解拼团的场景业务。你可以把这个过程就是当成你自己在承接一次产品需求，在学习的过程中把思考和扩展的点在评论区讨论，互相积累补充。 + +## 一、项目背景 + +>拼团系统可以用于，《小型支付商城》、《OpenAI应用》，这类带有支付场景购买商品的系统。我们这里以这样两个系统作为使用场景作为举例。也可以作用于任何其他的交易类系统。 + +针对目前的`小型支付商城系统`、`OpenAI应用系统`，商品购买交易同比增速放缓，需要引入新的营销策略促进商品交易量。在交易数据统计分析中得到，市场存在同类竞品，商品价格设定低于目前我们的商品定价，所以用户购买意愿偏低。 + +所以为了盘活沉睡用户，需要适当降低商品价格。但为了达到传播的效果，所以需要引入拼团方式，以客带客，靠用户自身传播的方式进行交易拉新。这样的处理方式对比于 KOL，会让利商品价值到用户自身。【KOL 等同于抖音大主播直播卖货】 + +
+ +
+ +另一方面，通过本项目的增加，逐步完善功能产品和运营服务体系，优化整体的产品架构，增强市场竞争力。 + +## 二、产品方案 + +因为我们所实现的是一个平台类系统，可以满足各类交易场景的拼团需求接入。所以在实现这套系统时候，不要与其他系统耦合。并提供相关的研发侧对接标准。 + +此外我们要提供前端案例对接展示，满足后续其他系统，如；《小型支付商城》、《OpenAI应用》对接时候有可参考样例。 + +### 1. 前端页面 + +

+ +
+ +- 首先，站在运营的角度，要为这次拼团配置对应的拼团活动。那么就会涉及到；给哪个渠道的什么商品ID配置拼团，这样用户在进入商品页就可以看到带有拼团商品的信息了。之后要考虑，这个拼团的商品所提供的规则信息，包括；折扣、时间、人数等。还要拿到折扣的一个试算金额。这个试算出来的金额，就是告诉用户，通过拼团可以拿到的最低价格。 +- 之后，站在用户的角度，是参与拼团。首次发起一个拼团与参与已存在的拼团进行数据的记录，达成拼团约定拼团人数后，开始进行通知。这个通知的设计站在平台角度可以提供回调，那么任何的系统也就都可以接入了。 +- 另外，为了支撑这套库表，也会有人群的设计。人群是互联网公司中非常常用的手段，比如要把所有符合某个条件的用户ID，全部写入到一个特定的 Redis 记录中，之后就可以专门为这些人做特定的拼团活动了。 +- 那么，拼团活动表，为什么会把折扣拆分出来呢。因为这里的折扣可能有多种迭代到一个拼团上。比如，给一个商品添加了直减10元的优惠，又对符合的人群id的用户，额外打9折，这样就有了2个折扣迭代。所以拆分出来会更好维护。这是对常变的元素和稳定的元素进行设计的思考。 \ No newline at end of file diff --git "a/docs/md/project/group-buy-market/\347\254\2541-3\350\212\202\357\274\232\347\240\224\345\217\221\347\263\273\347\273\237\350\256\276\350\256\241.md" "b/docs/md/project/group-buy-market/\347\254\2541-3\350\212\202\357\274\232\347\240\224\345\217\221\347\263\273\347\273\237\350\256\276\350\256\241.md" new file mode 100644 index 000000000..140d609ca --- /dev/null +++ "b/docs/md/project/group-buy-market/\347\254\2541-3\350\212\202\357\274\232\347\240\224\345\217\221\347\263\273\347\273\237\350\256\276\350\256\241.md" @@ -0,0 +1,34 @@ +--- +title: 【更】第1-3节：研发系统设计 +pay: https://t.zsxq.com/ESHMx +--- + +# 《拼团交易平台系统》第1-3节：研发系统设计 + +作者：小傅哥 +

+ +
+ +- group_buy_activity 拼团活动配置表中，融合了渠道和商品ID，属于和活动配置绑定了。 +- sku 商品信息，已经包含了渠道SC值和商品ID。而商品表咱们前面提到过，它是由接入方同步的商品信息，也可以不走这里，直接用 RPC/HTTP 接口查询数据，所以 sku 表不适合绑定互动ID。 +- 那么，就需要一个新的表来关联活动和商品信息配置，表名为 sc_sku_activity 必备字段；SC渠道、活动ID、商品ID。（自己创建库表后可以和课程的库表对比） +- 你可以根据这样的信息来创建你的库表，同时移除 group_buy_activity 表中 SC渠道值和商品ID。 + +## 二、业务流程 + +如图，整个改动流程的核心为让 MarketNode 节点的查询由原来方式改为先查询SC商品活动配置关联表，获得到活动ID，再查询活动信息。这期间如果有效的活动配置信息无，那么则走到 ErrorNode 节点，返回一个指定的错误码。 + +
+ +
+ +- 首先，你可以先通过如图的调用过程，理解本节要完成的编程动作。包括解耦后的新的库表关联关系。 +- 之后，编码的时候异步多线程查询商品关联配置，如果配置的信息为空，或者不存在有效的活动，那么可以返回一个 null。当拿到null 以后，可以做判断进行路由，走到 ErrorNode 节点。「这部分代码一定自己尝试下，多思考。」 \ No newline at end of file diff --git "a/docs/md/project/group-buy-market/\347\254\2542-7\350\212\202\357\274\232\344\272\272\347\276\244\346\240\207\347\255\276\350\212\202\347\202\271\350\277\207\346\273\244.md" "b/docs/md/project/group-buy-market/\347\254\2542-7\350\212\202\357\274\232\344\272\272\347\276\244\346\240\207\347\255\276\350\212\202\347\202\271\350\277\207\346\273\244.md" new file mode 100644 index 000000000..4f4da3c8f --- /dev/null +++ "b/docs/md/project/group-buy-market/\347\254\2542-7\350\212\202\357\274\232\344\272\272\347\276\244\346\240\207\347\255\276\350\212\202\347\202\271\350\277\207\346\273\244.md" @@ -0,0 +1,33 @@ +--- +title: 【更】第2-7节：人群标签节点过滤 +pay: https://t.zsxq.com/EL4gD +--- + +# 《拼团交易平台系统》第2-7节：人群标签节点过滤 + +作者：小傅哥 +

+ +- 首先，团购的商品下单。下单过程分为创建流水单、锁定营销优惠（拼团、积分、券）、创建支付订单、唤起收银台支付、用户扫码支付、支付完成核销优惠等。 +- 那么，这里用户以拼团方式下单，创建流水单完成后，需要与拼团系统交互，锁定营销优惠。更新流水单优惠金额和支付金额。接下来就可以创建支付单了（支付单需要最终的支付金额）。 +- 注意，拼团表 group_buy_order 除了有目标量（target_count）、完成量（complete），还要有一个锁单量（lock_count），当锁单量达到目标量后，用户在此组织下，不能在参与拼团。直至这些用户支付完成达成拼团或者锁单超时回退支付营销，空出可参与锁单量，这样其他用户可以继续参与。 \ No newline at end of file diff --git "a/docs/md/project/group-buy-market/\347\254\2543-1\350\212\202\357\274\232DeepSeek\350\256\276\350\256\241\346\213\274\345\233\242UI.md" "b/docs/md/project/group-buy-market/\347\254\2543-1\350\212\202\357\274\232DeepSeek\350\256\276\350\256\241\346\213\274\345\233\242UI.md" new file mode 100644 index 000000000..6b35c4ec2 --- /dev/null +++ "b/docs/md/project/group-buy-market/\347\254\2543-1\350\212\202\357\274\232DeepSeek\350\256\276\350\256\241\346\213\274\345\233\242UI.md" @@ -0,0 +1,36 @@ +--- +title: 【更】第3-1节：DeepSeek设计拼团UI +pay: https://t.zsxq.com/TnhqL +--- + +# 《拼团交易平台系统》第3-1节：DeepSeek设计拼团UI + +作者：小傅哥 +

课程：[https://t.zsxq.com/WCWAb](https://t.zsxq.com/WCWAb) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +**你说气人不**，每每公司`晋升提报`和`加薪`的时候，总是那些手里有俏活的👬🏻兄弟。业务项目虽然是根基，但大家都做也就拉不开差距，而技术类组件、通用服务、功能平台，倒不是所有人都能搞的，这类结合业务场景的提取共性问题，凝练成通用解决方案的项目，可以开发一个就解决了全大部门的问题，所以做这类项目很亮眼！ + +
+ +
+ +**这类项目也有门槛！** + +看着好像做个技术组件也没啥，但实际真想做的时候，你会发现你不知道什么服务可以被抽取为通用组件，不具备这样的经验和眼界。同时即使知道做啥了，也不知道如何结合像 Spring、MyBatis 源码能力，开发出一个通用的组件来，能让其他业务项目引入使用。 + +有人讲这东西不就是重复造轮子吗？🤔 还真不是，重复造轮子，指的市面上有的，或者公司里有个基础平台组有的。但这类的轮子往往不是深度结合业务的，而是那种无业务属性的功能逻辑的轮子，比如；rpc、xxl-job、mq 等。但一个业务组，他所需要的是解决通用业务场景问题的轮子，但这类东西又不属于基础平台研发组，所以往往都是业务组自己来解决这类场景问题。 + +所以，让自己具备开发组件的能力，是非常非常重要的，这即是抽象业务也是驾驭源码的能力体现。 + +小傅哥已经为大家提供了非常多的通用组件项目，如；`扳手工程（DCC动态配置中心、设计模式、动态限流、任务调度）`、`BCP 透视业务监控`、`动态线程池`、`支付SDK组件`、`SpringBoot Starter （16个合集）`、`IntelliJ IDEA Plugin 插件开发能力（具备这个的，开发了不少AI类组件）`。 + +这次小傅哥给大家再加一个新的组件《本地任务消息组件》，该组件解决业务场景远程调用HTTP或推送MQ消息，最终一致的问题。 + +## 一、能学到啥 + +- 【架构】掌握 DDD 分层与端口-适配器模式，清晰划分 domain/infrastructure/trigger/config 模块，提升可维护性与扩展性。 +- 【后端】学习注解+AOP 方式受理任务消息，结合事务边界进行统一处理，理解 `@LocalTaskMessage` 与切面配合的落地实践。 +- 【后端】掌握本地消息表设计与分片扫描策略（按门牌号 houseNumber 分片），实现高效拉取与顺序处理，提升系统可靠性。 +- 【后端】熟悉 Spring Event 事件驱动与异步消费，使用 `ApplicationEvent`+`@EventListener`+`@Async` 实现解耦通知链路。 +- 【后端】实践策略模式实现可插拔通知能力，支持 HTTP 与 RabbitMQ 两种通知通道，并在成功/失败时更新任务状态。 +- 【后端】熟练使用 OkHttp3 与 Retrofit2 统一封装 HTTP 网关，掌握动态 URL、Header、Body 的组合与异常处理。 +- 【后端】了解 RabbitMQ 事件发布的可选依赖注入方式，避免未配置 MQ 时的强依赖导致应用启动失败。 +- 【配置】掌握 `@ConfigurationProperties` 驱动的多任务组动态调度配置，支持 cron 与 fixedDelay 两种触发方式，并可配置批次大小 limit。 +- 【运维】学习 `ThreadPoolTaskScheduler` 的线程池化调度管理，合理设置线程名与池大小，提升任务调度的可观测性与稳定性。 +- 【数据】掌握原生 JDBC 访问与 DAO 封装，完成插入、状态更新、分片条件查询、最小游标查询等落地实现。 +- 【测试】通过示例命令对象 `TaskMessageEntityCommand` 的构建与调用，理解入参约定、枚举策略与配置对象的协作。 +- 【实践】提升异常、日志与枚举的综合使用能力，建立稳定的错误处理。 + +## 二、项目介绍 + +**《本地消息任务组件》** 项目，是以自定义注解 AOP 切入或编程的方式，动态化完成数据库表事务和消息推送（HTTP、MQ），达到最终一致性的目的。 + +>在没有这样的组件的时候，为了完成业务流程的同时，在发送一个MQ消息或则远程调用 HTTP 操作，都需要自己写一个本地消息表，之后还要维护消息表的扫描补偿。 + +操作方式如图； + +
+ +
+ +- 用户可以选择通过注解或者直接调用组件服务的方式进行使用。也就不用业务项目工程再维护关于本地消息表的写入和 MQ 或者 HTTP 的处理和补偿了。 +- 注解方式，会自动获取入参，入参需要为 TaskMessageEntityCommand 对象，它可以是某个入参的对象。之后配置 req.command 也可以获取。 + +## 三、产品方案 + +### 1. 产品概述 + +本地任务消息组件基于 Spring 框架能力，设计并实现了通用功能内核，便于集成到各类业务系统中。在业务系统中，组件支持在事务内完成数据写库的同时，写入一条本地消息记录（需在业务系统数据库中创建符合组件规范的本地消息表）。写入完成后，组件同步推送 Spring 事件，触发事务外的异步处理，如 MQ 消息发送或 HTTP 回调。即使异步处理失败，组件内置的本地消息表定时任务（支持自定义配置“门牌号”多任务并行扫描，提升扫描吞吐量）会持续检测并重试通知，确保消息最终一致性和业务流程的可靠执行。 + +### 2. 技术架构 + +
+ +
+ +- 首先，Local Task Message 任务消息组件，是以解决通用业务场景中的，本地数据库事务和外部MQ/HTTP调用一致性问题而设计实现的。让上游业务系统，不需要在每个流程中，都要做大量的重复编码。而是通过注解或者直接调用组件内核服务即可完成消息的通知操作。 +- 之后，Local Task Message 任务消息组件，并不是一个单纯的工具性功能，而是剩余一个领域服务内核，它具备完整的领域功能，具备操作数据库表的能力，以及接收 Spring Event 事件，对接 MQ、HTTP 完成和外部的交互处理。 +- 然后，上游系统在使用这套服务时，只需要配置好对应的本地消息表（一个事务下，连的同一个库），以及引入组件和完成yml配置，即可直接使用。 + +### 3. 功能流程 + +
+ +
+ +- 引入本地消息组件后，以用户开发dao入库操作为开始，可以通过注解或者调用组件服务 `ILocalTaskMessageHandleService` 驱动同一个事务下，进行消息推送。 +- 切面的方式，会更为优雅简洁，不需要用户自己在维护调用关系。 +- 整个操作会由组件自行处理写库操作，基于 Spring Event 的监听和通知，触发消息推送。完成 http、mq 的调用逻辑。同时还有基于门牌号扫描的逻辑，增强吞吐量。 + +## 四、课程目录 + +现课程已全部录制完成，接下来会日更📅项目💐； + +

+ +
+ +1. 营销，是一个非常庞大的系统体系。包括众多的模块组成，其中抽奖只是一个重要的微服务之一。 +2. 包括，营销平台、返利平台、积分账户、抽奖系统、券系统、灌券系统、售卖系统，以及各类玩法的组件系统。它们的关系如图所示。 + +### 2. 为什么自研路由组件 + +如果面试问：“为什么要自研，市面不是有吗，怎么回答？” 可以从以下3个点解答； +1. 维护性；市面的路由组件比如 shardingsphere 但过于庞大，还需要随着版本做一些升级。而我们需要更少的维护成本。 +2. 扩展性；结合自身的业务需求，我们的路由组件可以分库分表、自定义路由协议，扫描指定库表数据等各类方式。研发扩展性好，简单易用。 +3. 安全性；自研的组件更好的控制了安全问题，不会因为一些额外引入的jar包，造成安全风险。 + +当然，我们的组件主要是为了更好的适应目前系统的诉求，所以使用自研的方式处理。就像shardingsphere 的市场占有率也不是 100% 那么肯定还有很多公司在自研，甚至各个大厂也都自研一整套分布式服务，来让自己的系统更稳定的运行。分库分表基本是单表200万，才分。那么面试怎么说； + +你们为什么分库分表？ + +1. 我们分库分表用的非常熟。但不能为了等到系统到了200万数据，才拆。那么工作量会非常大 +2. 我们的做法是，因为有成熟方案，所以前期就分库分表了。但，为了解释服务器空间。所以把分库分表的库，用服务器虚拟出来机器安装。这样即不过多的占用服务器资源，也方便后续数据量真的上来了，好拆分。 +3. 同时，抽奖系统，是瞬时峰值较高的系统，历史数据不一定多。所以我们希望，用户可以快速的检索到个人数据，做最优响应。因为大家都知道，抽奖这东西，push发完，基本就1~3分钟结束，10分钟人都没了。所以我们这也是做了分库分表的理由。 + +### 3. 规则引擎的设计目的 + +1. 面试官您好。关于规则引擎这块，首先；这是一个基于降低重复编码和提高可维护性的，并需要符合当前项目诉求的，同时不过渡的设计和减少运维成本的前提下，在技术调研后所做的微型规则引擎设计实现。 +2. 此规则引擎的主要作用是解决，抽奖业务场景中对个性化运营诉求的处理，如；人群身份标签、交易记录、活动资格、授信状态等规则的可配置化的交叉使用。 +3. 所以基于这样的情况，此规则引擎的设计是一个二叉树判断，实现手段运用到了组合模式、工厂模式等。并为了便于维护和使用，进行了库表对二叉树的抽象设计，树根、节点、子叶，映射为二叉树编码的相关属性信息。同时，也可以基于这样的库表做前端页面的托拉拽配置操作，降低运营成本。 +4. 最后，其实动态的规则引擎配置，其实放大了看就是 BPMN + Drools + Groovy，的一个低代码实现框架。综上，面试官这个就是我在做规则引擎设计的一些思考、调研和落地。如果以后咱公司有其他更大的场景，我也可以扩展为 Reta 算法和低代码方案进行架构落地实现。 + +### 4. 秒杀的滑块锁讲解 + +1. 是针对于用户参与的活动库存加锁的，如果是独占锁是针对于活动ID加锁的。 +2. 滑块锁的核心是去竞态，避免独占影响系统的响应性能。关于此类锁，这里又做了视频做了详细的讲解；[Redis | bugstack 虫洞栈](https://bugstack.cn/md/road-map/redis.html) - 如图。别看提秒杀一堆人说，但如果还讲用独占锁做活动的秒杀场景，就没做过大规模的秒杀。独占是会很大概率出事故的。 +3. 那为什么加一个锁呢，incr 不就可以。加锁是兜底，你不知道什么时候会出现 incr 不对的情况。如；集群配置问题【特例】、出现redis问题，需要恢复库存。如果没有锁，可能会超卖。[https://t.zsxq.com/12sNS4E2J](https://t.zsxq.com/12sNS4E2J) - 第一条评论加了说明。 +4. 对于非交易的活动类场景，要的就是一个快。快速响应、快速释放，可接受容错失败概率。但不要磨磨唧唧影响我的主核心交易链路。但凡在618、双11，营销敢超时，就直接下掉。保证用户可下单可支付。否则这黄金时间点，你耽误1分钟都是几个亿的成交额。所以，这类营销秒杀场景下，根本就是保证不超卖，也不恢复库存。 + +注意：独占锁是加给个人流程的 - 无资源竞争，如贷款单受理。分段/滑块/无锁化，是加给库存的 - 有资源竞争，如秒杀、商品发货等集中资源类。就跟大超时的收银台一样。原来就1个出口，后来一排出口，在后来又有无人化的电子出口。点点那个软件。 + +举例；incr 的速度很快，就像进入了公共的卫生间🚾。一个坑一个门，谁进去谁就锁上。没有就跑到下一个门。你说你不锁门吧，也没问题。但别人不知道，一拽开就比较尴尬。所以要加锁，锁门。 + +## 四、面试刷题 + +- [关于抽奖系统怎么写到简历里](https://t.zsxq.com/07yKZJFkR) +- [抽奖系统，面试被问到表的设计，要怎么答？](https://t.zsxq.com/04EYNRF6m) +- [抽奖系统一般部署多少实例比较合适，系统大概能抗住多大的流量？](https://t.zsxq.com/04zNzZVFa) +- [抽奖系统为什么自研路由组件？](https://t.zsxq.com/04Am6mIqR) +- [抽奖项目分布式事务如何解决?](https://t.zsxq.com/04yzF27UB) +- [抽奖系统 TPS 5000~8000 服务器配置大概情况](https://t.zsxq.com/04fA6meyB) +- [抽奖系统mq重发的时候是怎么保证幂等性](https://t.zsxq.com/04ZrJYBy7) +- [面试时抽奖系统被问到类似qps、tps这些指标如何回答？](https://t.zsxq.com/04eqV7YNf) +- [问分库分表，别给我回答分2个库，每个库4个表，那你分那个毛用，一看就是假的](https://t.zsxq.com/04y3FAmq3) +- [想问问大家在面试的时候自我介绍，是怎么介绍抽奖项目的，个人项目还是公司项目？](https://t.zsxq.com/04BMN7myv) +- [说一下抽奖系统拓扑结构](https://t.zsxq.com/043BiQje6) +- [聚合和聚合根在抽奖系统的体现?](https://t.zsxq.com/04jyRjA6I) +- [抽奖系统DDD和MVC的区别](https://t.zsxq.com/04EAameYz) +- [描述你遇到的一个技术问题-抽奖事故及优化](https://t.zsxq.com/04EuvJe6U) +- [为什么用户领取活动完毕，发送MQ去更新数据库中的库存](https://t.zsxq.com/04vjAq3RR) +- [量化规则引擎是一个组件，如果有一个新的业务进来，如何复用?

DDD 是什么 + +那 DDD 是什么呢？来自于维基百科的一段定义：["Domain-driven design (DDD) is a major software design approach. "](https://en.wikipedia.org/wiki/Domain-driven_design)，DDD 是一种软件设计方法。也就是说 DDD 是指导我们做软件工程设计的一种手段，它提供了用切割工程模型的各类技巧，如；领域、界限上下文、实体、值对象、聚合、工厂、仓储等。通过 DDD 的指导思想，我们可以在前期投入更多的时间，更加合理的规划出可持续迭代的工程设计。 + +在 DDD 中有一套共识的工程两阶段设计手段，包括；战略设计、战术设计。 + +- **战略设计**，主要以应对复杂的业务需求，通过抽象、分治的过程，合理的拆分为独立的多个微服务，从而分而治之。与之评价拆分的是否合理，则是在需求开发上线时候，是否每次都大量操作多个微服务开发和上线。这样的战略设计是一种失败的微服务单体设计。所以少数几个中等规模的单体应用，周围环绕着一个服务生态系统，这更有意义。[你实际上并没有构建微服务 @贾斯汀·埃瑟里奇](https://www.simplethread.com/youre-not-actually-building-microservices/) + +- **战术设计**，在这个范畴下，主要以讨论如何基于面向对象思维，运用领域模型来表达业务概念。通常在不做领域模型设计的架构，也就是通常映射到 MVC 三层架构下，`Service + 数据模型`的开发模式，会让 Service 扁平的、大量的，平铺出非常复杂的业务逻辑代码。再加上行为对象与功能逻辑的分离，贫血模型的开发方式，让行为对象的不断交叉使用，也是让系统不断增加复杂度，并到难以维护的根因。所以这一阶段要设计每一个可以表达领域概念的模型，并运用实体、聚合、领域服务来承载。 + +## 2. DDD 的概念 + +什么是充血模型，领域内都包括什么，实体、聚合、值对象，有什么区别？这样一些"为什么"的概念，也是战术设计过程中非常重要的知识项。搞清楚它们才能做 DDD 设计。 + +### 2.1 充血模型 + +**充血模型**，指将对象的属性信息与行为逻辑聚合到一个类中，常用的手段如在对象内提供属于当前对象的`信息校验`、`拼装缓存Key`、`不含服务接口调用的逻辑处理`等。 + +
+ +
+ +- 这样的方式可以在使用一个对象时，就顺便拿到这个对象的提供的一系列方法信息，所有使用对象的逻辑方法，都不需要自己再次处理同类逻辑。 +- 但不要只是把充血模型，仅限于一个类的设计和一个类内的方法设计。充血还可以是整个包结构，一个包下包括了用于实现此包 Service 服务所需的各类零部件（模型、仓储、工厂），也可以被看做充血模型。 +- 同时我们还会再一个同类的类下，提供对应的内部类，如用户实名，包括了，通信类、实名卡、银行卡、四要素等。它们都被写进到一个用户类下的内部子类，这样在代码编写中也会清晰的看到子类的所属信息，更容易理解代码逻辑，也便于维护迭代。 \ No newline at end of file diff --git "a/docs/md/project/s-pay-mall/part-1/\347\254\2542\350\212\202\357\274\232DDD \345\273\272\346\250\241\346\226\271\346\263\225.md" "b/docs/md/project/s-pay-mall/part-1/\347\254\2542\350\212\202\357\274\232DDD \345\273\272\346\250\241\346\226\271\346\263\225.md" new file mode 100644 index 000000000..a0239bfa2 --- /dev/null +++ "b/docs/md/project/s-pay-mall/part-1/\347\254\2542\350\212\202\357\274\232DDD \345\273\272\346\250\241\346\226\271\346\263\225.md" @@ -0,0 +1,40 @@ +--- +title: 第1-2节 DDD 建模方法 +pay: https://t.zsxq.com/teMSw +--- + +# 《小型支付商城系统》第1-2节 DDD 建模方法 + +作者：小傅哥 +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +**什么是系统的工程结构，工程框架的作用是什么？** + +其实，工程结构的存在作用目的，是为了承载工程系统开发的模型划分，定义工程服务开发过程中实施标准。说白了，就是你在工程实现时，在哪个层访问数据库、哪个层使用缓存、哪个层调用外部接口、哪个层做功能实现，这就是工程框架结构定义的目的。 + +但在 `Service + 贫血模型` 的三层结构开发指导下，是没有细分出面向对象工程结构设计的趋于划分的。所以在通常意义的 MVC 下，开发过程所有需要的内容，都会堆砌到 Service 实现类中。这也是为什么 DDD 领域驱动设计的落地工程结构，会出现；洋葱架构、整洁架构、菱形架构、六边形架构等这些架构模型。因为我们需要更细致的划分，来承载 DDD 设计概念中映射的领域、仓储、适配、编排、触发，并重视面向对象过程。—— 其实你一上学，学Java就开始学面向对象了，只不过一点点在忘记它。 + +## 一、为啥需要架构 + +说到开发代码为啥需要架构，就想买了个房子，为啥要隔出厨房、客厅、卧室、卫生间一样，核心目的就是让不同的职责分配到不同的区域内。虽然在代码中是没有马桶要放卫生间、沙发要放客厅、床要放卧室。但他有一些列的科目信息要引入到工程。 + +**在工程开发时会涉及到的核心科目；** + +
+ +
+ +如；统一的异常、数据库的连接、日志的打印、外部服务的调用、消息的监听、任务的轮训以及服务的实现等一些列的东西要处理，分配到不同的工程包下承载。在 DDD 之前，我们一直用 MVC 的分层结构承接这些内容； + +
+ +
+ +通用的、配置的、组件的、持久化的、内部的、外部的，在以往的单体应用时代开发下，其实是没有这么多东西的，那时候的工程结构都偏向于 Service + 贫血模型实现。 + +但随着微服务的演进，越来越多的内容被填充到工程中，这个时候你细心的查看架构，就会发现原本的 MVC 结构其实已经变的非常混乱了。一个 Service 中为了实现自己的功能，要引入一堆的东西，这些原子的功能与 Service 自身的服务耦合在一块。也导致了工程的维护成本越来越大。 + +>这样的三层工程结构分配方式，对于要承载庞大的分布式技术栈体系显然是有点小马拉大车，三缸机带不动SUV一样。 + +## 二、工程结构设计 + +2004年，Eric Evans 在发表了一部名为《Domain Driven Design》的著作。2005年 Alistair Cockburn 提出的“六边形关系图”理论，2008年 Jeffrey Palermo 提出了洋葱架构。虽然这些架构并不是专门为 DDD 而出，但巧的是这些架构都在 DDD 一书发表之后陆续推出新的架构模型。同时这些架构的分层设计方式也都与 DDD 非常契合，在这些架构下也可以很好的落地 DDD 设计方法。 + +
+ +
+无论是六边形架构，还是洋葱架构，或是[张毅老师](http://zhangyi.xyz/)提到的南向网关/北向网关的菱形架构，他们的目标都是以领域服务为核心，隔离内部实现与外部资源的耦合。 + +在 DDD 分层架构下，以支撑 domain 核心领域实现拆分出基础设施（infrastructure），来承接对外部资源的调用。触发器（trigger）向外部提供服务。之后 app 为应用启动、api 为接口定义、types 为通用信息、case 为编排。 + +在这样一套结构下，用于开发工程的各项科目也可以被优雅的分配到各个分层结构了。相对于 Service + 数据模型的贫血模型结构，现在就主要以 domain 为核心开发业务功能，不会在 domain 工程模块下，引入其他各类外部组件了，这样就可以更加关心业务功能开发。 + +之后是这样的思想映射到工程中，常见的分层结构会有两套，一套是整洁分层，另外一套是六边形分层。 \ No newline at end of file diff --git "a/docs/md/project/s-pay-mall/part-2/\347\254\2541\350\212\202\357\274\232\345\260\217\345\236\213\346\224\257\344\273\230\345\225\206\345\237\216\351\234\200\346\261\202\350\256\276\350\256\241.md" "b/docs/md/project/s-pay-mall/part-2/\347\254\2541\350\212\202\357\274\232\345\260\217\345\236\213\346\224\257\344\273\230\345\225\206\345\237\216\351\234\200\346\261\202\350\256\276\350\256\241.md" new file mode 100644 index 000000000..5197a4c88 --- /dev/null +++ "b/docs/md/project/s-pay-mall/part-2/\347\254\2541\350\212\202\357\274\232\345\260\217\345\236\213\346\224\257\344\273\230\345\225\206\345\237\216\351\234\200\346\261\202\350\256\276\350\256\241.md" @@ -0,0 +1,32 @@ +--- +title: 第2-1节：需求PRD讲解 +pay: https://t.zsxq.com/2iM7V +--- + +# 《小型支付商城系统》第2-1节：需求PRD讲解 + +作者：小傅哥 +

+ +
+ +- 首先， w13scan 的流程是这样，你需要先启动一个这样的被动扫描服务，之后再你的浏览器中配置网页请求代理地址。这个代理地址就是 w13scan 服务。 +- 那么，这个时候你所有在浏览器发起的请求，都会经过 w13scan 走一圈。这样，就可以把请求的网址进行一系列安全扫描检查，查看是什么样的漏洞。 +- 另外，w13scan 不只是可以被动扫描还可以主动配置路径扫描一个固定的网站地址检测。 +- 最后，w13scan 会把扫描到的安全漏洞以html方式展示出来，我们可以在这个网页上查看漏洞检测结果。也就可以在进一步对存在的漏洞进行挖局，如拿到 heapdump 在解析它的信息了。 + +## 二、案例工程 + +这里小傅哥为你提供了完整的案例测试工程，你可以直接完整体验。`你需要有 docker 环境或者 Python 3.6+` + +
+ +
+ +地址：[https://github.com/fuzhengwei/xfg-dev-tech-w13scan-jdumpspider](https://github.com/fuzhengwei/xfg-dev-tech-w13scan-jdumpspider) + +- 首先，你需要下载这个工程到本地电脑，便于安装环境和测试。 +- 如图，已经为你描述了案例的功能。 + +## 三、被动扫描 + +**源码**：[https://github.com/fuzhengwei/w13scan](https://github.com/fuzhengwei/w13scan) - 小傅哥 fork 的 w13scan 并做了镜像打包。源码文档里提供了安装和使用说明。 + +### 1. 组件安装 - docker 方式 + +```java +# docker-compose -f docker-compose.yml up -d +version: '3.8' +services: + w13scan: + image: fuzhengwei/w13scan:1.0 + container_name: w13scan + ports: + - "7778:7778" + volumes: + - ./output:/w13scan/W13SCAN/output + entrypoint: ["python3", "w13scan.py", "-s", "0.0.0.0:7778", "--html"] + tty: true +``` + +
+ +
+ +- 你可以通过脚本 `docker-compose -f docker-compose.yml up -d` 脚本执行 w13scan 的服务安装。 +- 另外，如果你不能执行 docker-compose 还可以通过提供的 `docker run -d --name w13scan -p 7778:7778 -v ./output:/w13scan/w13scan/output fuzhengwei/w13scan:1.0 python3 w13scan.py -s 127.0.0.1:7778 --html` + +### 2. 组件安装 - Python 方式 + +这个方式就把代码拉到自己本地，进行构建和启动。 + +
+ +
+ +```java +git clone https://github.com/fuzhengwei/w13scan.git +cd w13scan # 进入git目录 +pip3 install -r requirements.txt +cd W13SCAN # 进入源码目录 +python3 w13scan.py -h +``` + +```java +python3 w13scan.py -s 127.0.0.1:7778 --html # 端口可省略，默认为7778,开启--html即实时生成html报告 +``` + +- 安装完成后启动，也可以看到一个 ` HTTPServer is running at address('0.0.0.0','7778')......` 日志。 + +### 3. 代理配置 + +无论使用那种方式部署，启动完成后，都需要给浏览器配置代理。其实也就是你的电脑的网络哪里配置下代理。 + +
+ +
+ +- 给你的网络配置代理服务，我这里是 mac 电脑点网络wifi那里进入的配置。你可以找到你的位置进行添加。 + +### 4. 下载证书 + +下载：[http://w13scan.ca/](http://w13scan.ca/) + +一定是你服务启动成功，代理配置成功。那么你在点击下载后，才能下载一个 `download.crt` 文件。之后双击点开信任即可。 + +### 5. 开始使用 + +一切配置成功后，你可以在浏览器访问你想检查漏洞的网址，一段时间后就可以看到被动扫描组件检测的数据信息了。之后进入到 `w13scan/W13SCAN/output` 查看检测文件了。这些 html 文件直接用浏览器打开和刷新即可。 + +
+ +
+ +
+ +
+ +- 现在你就看到一些展示的系统安全漏洞了，再根据这些漏洞进行**友好的访问** + +## 四、heapdump 下载 + +测试前你可以先启动 xfg-dev-tech-w13scan-jdumpspider 应用。这样就可以做后面的流程以及获取 heapdump 日志了。 + +### 1. 问题背景 + +测试工程中的 yml 配置。这个配置为了配合普罗米修斯做监控使用的，但要注意如果只是这样配置，是很有风险的。 + +```java +# 监控 +management: + endpoints: + web: + exposure: + include: "*" + endpoint: + health: + show-details: always + metrics: + export: + prometheus: + enabled: true + prometheus: + enabled: true +``` + +- 如果你的 SpringBoot 系统配置了这样的监控，并且没有配置相关的安全校验，Spring Security 那么现在你就暴漏了自己的端点。 + +### 2. 端点访问 + +地址：[http://127.0.0.1:8091/actuator/env](http://127.0.0.1:8091/actuator/env) + +

博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！ + + + +大家好，我是技术UP主小傅哥。 + +天才般的发明，**ai ssh 命令行工具**，让 ai 的使用不只局限在 `ai 对话提问`、`ai idea 辅助编码`，也可以直接让操作系统具备 ai 能力。其实这才是我一直想要的东西！😄 + +
+ +
+ +**ai 正在改变产品设计！** + +2025年，是 ai agent 智能体爆发的一年，它所提效的接入方式可以分三层来看； + +先是中间这一层，是 ai agent 接入服务和软件，像是大家使用的 trae.ai 或者小傅哥分享过的 [draw.io + ai](https://bugstack.cn/md/road-map/draw.io.html)，以及各个互联网公司用 ai 提效做的一些场景客服，系统巡检，日志分析等。 + +之后上面这一层，是从用户视角，模拟用户行为使用软件，而不是直接接入到软件api上。它使用的方式是 AutoGLM-Phone-9B 手机模型，以 ADB 或者无障碍模式，让手机可以接收用户指令，完成操作。如；`打开京东，搜索东北老式麻辣烫，加入购物车，以默认地址，进行支付购买。下单支付完成后，微信发给xxx告诉，她预计送达时间。` 如果感兴趣，可以基于这篇文章进行实践。[《手机 + agent，这是要掀桌子！》](https://bugstack.cn/md/algorithm/model/autoglm-phone-agent.html) + +然后底下这一层，是从系统层面，不再依赖于直接对接某个软件，某个api，而是以系统层面直接操作软件，或者完成整个行为动作。如，在云服务器/本地，配置好 jdk、maven、docker 环境，之后帮我拉取 git clone xxx 仓库代码，本地完成 maven 构建和启动。以及在遇到问题时候，让 ai 直接检索并处理都是非常可以的。 + +好，那接下来，小傅哥给大家分享下，如何安装一个 ai ssh 工具（没有这个教程，很多人是安装不上的！）。 + +>🧧 文末提供了小傅哥所有编程实战项目获取方式，一次加入即可获得19个已完结的实战项目，也有非常多的 AI 类项目，一定要补充学习！ + +## 一、工具介绍 + +ai ssh 是命令行工具，可以安装到 Mac、Windows、Linux 上，以通过 terminal（终端）直接操作系统进行使用。它的场景也包括你打开的 IntelliJ IDEA 下面的 terminal 终端中使用，这样就天然的嵌入到了 IntelliJ IDEA 中了，非常方便。 + +目前这类的 ai ssh 命令行工具软件也非常多，包括；[opencode.ai](https://opencode.ai/)、[claude](https://claude.com/product/claude-code)、[openai codex](https://github.com/openai/codex)、[阿里千问 - qianwen code](https://github.com/QwenLM/qwen-code)，都出了对应的软件。 + +在整体体验后，效果还是都不错的，这里是 opencode 的终端使用截图； + +
+ +
+ +- opencode 默认提供了一些免费模型，可以输入 `/models` 进行选择。 +- 另外还可以通过配置文件，添加其他模型，如 claude 模型、openai 模型、小米模型等。 + +## 二、软件安装 + +以下软件安装，会需要用到 gcc、nodejs 20+ 版本，建议安装 Ubuntu 24 版本，可以不需要折腾系统环境。 + +### 1. 脚本说明 + +这软件好用是挺好用，但它的源都在 Github 上，很多伙伴在执行官网脚本 `curl -fsSL https://opencode.ai/install | bash` 是安装不上的。所以，小傅哥做了一个对应的脚本，方便大家更加简化的安装使用。 + +
+ +
+ +- 脚本（gitcode）：[https://gitcode.com/Yao__Shun__Yu/xfg-dev-tech-docker-install](https://gitcode.com/Yao__Shun__Yu/xfg-dev-tech-docker-install) +- 脚本（github）：[https://github.com/fuzhengwei/xfg-dev-tech-docker-install](https://github.com/fuzhengwei/xfg-dev-tech-docker-install) + +### 2. 脚本下载 + +```java +git clone https://gitcode.com/Yao__Shun__Yu/xfg-dev-tech-docker-install.git +``` + +- 你可以通过命令的方式把脚本拉取到本地电脑或者云服务器上。 + +### 3. 脚本授权 + +```java +find . -name "*.sh" -type f -exec chmod +x {} \; +``` + +- 全部授权 + +```java +chmod +x terminal.sh +``` + +- 指定授权 + +### 4. 执行安装 + +
+ +
+ +```java +./terminal.sh +``` + +- 执行安装时，选择1，opencode code，这个是比较推荐的。 +- 无论是 Windows、Mac、Linux 都可以使用这个脚本进行安装，我已经做好了对应的脚本。 +- 安装完成后，需要输入 `opencode` 之后 Enter（回车）进入到系统中。如果提示 opencode 不是有效的命令，可以检查是否安装过程中有个提示 `source .../bashrc` 可以自行执行刷新。 + +## 三、软件配置 + +### 1. 命令使用 + +
+ +
+ +
+ +
+ +- `/init` - 创建/更新 Agents.md" +- `/review` - 检查变化" +- `/new` - 创建新的会话" +- `/models` - 选择模型" +- `/agents` - 智能体方式" +- `/session` - 会话列表" +- `/status` - 查看状态" +- `/mcp` - 选择mcp服务" +- `/theme` - 选择主题" +- `/editor` - 编辑" +- `/connect` - 链接模型提供者" +- `/help` - 帮助" +- `/commands` - 命令" +- `/exit` - 调试模式" + +> 这些可能会随着版本更新而调整，你可以依次尝试下。 + +### 2. 配置模型（自定义 - 可选） + +
+ +
+ +
+ +
+ +```java +{ + "$schema": "https://opencode.ai/config.json", + "provider": { + "my-model-openai": { + "npm": "@ai-sdk/openai-compatible", + "name": "OpenAPI", + "options": { + "apiKey": "你的apikey", + "baseURL": "https://你的baseURL/v1" + }, + "models": { + "gpt-4.1": { + "name": "gpt-4.1" + } + } + }, + "my-model-glm": { + "npm": "@ai-sdk/openai-compatible", + "name": "GLMAPI", + "options": { + "apiKey": "你的apikey", + "baseURL": "https://open.bigmodel.cn/api/paas/v4" + }, + "models": { + "glm-4.7": { + "name": "glm-4.7" + } + } + } + }, + "model": "my-model-openai/gpt-4.1" +} +``` + +- 如果你想自己更换下模型，比如使用 openai 的或则 claude 的，那么需要你在脚本下的 terminal/opencode.json 进行更换，之后执行 `./opencode.json.sh` 进行创建。 +- 如果先执行了 ``./opencode.json.sh`` 之后想更换配置的模型，则可以通过 vim 命令，编辑 `/root/.config/opencode/opencode.json` +- 其他的还有一些像是 mcp 的配置，可以参考官网（避免调整了配置错），[https://opencode.ai/docs/mcp-servers/](https://opencode.ai/docs/mcp-servers/) + + +## 三、软件使用 + +### 1.

+ +
+ +最近一段时间受不少 AiGC 类广告的影响，`文生图`、`文生视频`、`故事成片`，在家动动手就能赚钱。一个视频都几千、几万的点赞。 + +听起来做这个也挺简单，让 DeepSeek 生成口播故事，把故事放到 AiGC 软件（现在一堆），选择故事成片，在把视频上传到抖音、快手、头条，完活！**就是不赚钱！** + +>本文会分享 AiGC 视频制作的过程和注意点。另外作为技术人员，我们可以自己部署一个文生视频的软件服务，以及了解相关的 API 技术，也为后续自己开发 AiGC 做积累。 + +## 选择一个赛道！下场！ + +首先，你可以想好一个创作的主题，如果有多个主题，可以分别投放到不同的软件平台，尽量先垂直一个系列更新，如果一直没有流量，后面可以干掉重新换主题来。 + +主题可以包括；`婆媳关系`、`中老年相亲`、`农村故事`、`鬼故事`、`好看的景色+音乐`、`儿童诗歌`，也就是你尽量要找一些高频有大量客群的场景，只要推荐到这样的人群标签下，视频的播放量还是很高的。 + +
+ +
+ +但不要想着这样就能赚钱，如果只是试试水，基于 DeepSeek 生成关键信息的故事（主题、背景、人物、故事线），再把故事放到文生视频完成后上传即可。**但这样做好，基本属于徒劳！** + +在我尝试推了几个鬼故事后，没有看到什么流量，这时候有个哥们加我，说我这样推没用的。我也好奇的去加了下关注，他是专门做鬼故事系列的，每个内容都很精良，而且属于 TM 鬼故事 + 擦边！还备注上（收徒）！ + +
+ +
+ +所以，从这块开始，我发现要想让一个内容有较不错的流量，需要以下几点； + +1. 故事主体框架是明确、不能纯用 DeepSeek 来写。故事可以基于一些比较火的小说来制造。看过越多小说的，做这方面越有优势。 +2. 故事内容太干净了也没有人看，在 DeepSeek + 文生视频允许的范围内，你都可以“肆意”创作。 +3. 如果你时间更多，也更想做好，那么要对生成的视频，逐帧剪辑，也可能要多生成几次来使用。并制造好吸引人的封面！ +3. 长期主义，1~3，你可以都不用考虑。而是真的一点点来结合 AI 来写长期有意义的故事。 + +**不过，就算以上这样你都做了，也可能一点流量都没有！**😂 + +## AiGC 软件工具 + +在有了内容以后，就是 AI 生成视频了。AI 生成视频的软件有很多，基本也都是付费的。😂 所以说，你不一定赚不赚钱，但 AI 创作课程和 AI 软件是赚钱。 + +我体验了，可灵 AI、录咖 AI，还有抖音剪映自带的 AI 生成类工具。可灵 AI 适合文生图片、数字人口播，剪映 AI 适合文生视频。因为我本身就需要日常剪辑视频，开了剪映会员，所以可以直接使用。可灵 AI 是少量付费体验了下。 + +
+ +
+ +- 剪映 APP 有个 AI 图片成片，进入后选择 AI 故事成片。 +- 你可以把 DeepSeek/AI 生成口播故事（2000字 - 3000字），放进来转换即可。完成后，把视频下载下来，上传到你的各个平台。 + +## 我以为一分钱也赚不到的时候！ + +**在我折腾了快一周，以为分币赚不到的时候，来活了！** + +有个“粉丝”，关注了我。给我讲，接活不。我问啥活，她说，关注这个没事主播，点赞视频和收藏，完成后给6块钱。我没想到，她真给！ + +
+ +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +在互联网大厂应用系统开发中，有一项非常重要的技术手段，保证新迭代功能的可靠性。虽然，这像技术也不是“银弹（啥都能搞定）”，但缺少这项技术，对于极其复杂的业务场景新上线功能，总感觉心里没底！—— 它就是`流量录制`和`流量回放`！ + +
+ +
+ +**如何保证系统的可靠性？** + +互联网大厂toc场景，非常重视交付的可靠性，甚至大于交付的效率性。所以，在整个研发声明周期过程中，要有 PRD 评审、研发设计代码、代码评审、代码分支合并评审，以及在这个过程中还有测试人员进行全流程的验证。 + +但即使这样，面对经历了数十年迭代的系统，单工程甚至几十万行代码，极其复杂的业务系统流程，测试也是可能会出现疏漏。这种疏漏如，虽然非本次需求迭代的场景，但是其他业务场景因当前系统的一个枚举，一个参数的变动，都会影响到数十条业务。哪怕不是代码变动，仅仅是重构了小部分代码块，调整了前后顺序，当前业务无影响，但确影响了某次其他任务的跑批结果！ + +一次事故，可能是扣绩效和年终奖，也可能是影响晋升提名，还可能是直接毕业🎓啦！所以，在互联网大厂班组🧱搬砖，会学到很多高级技巧，来保证系统的可靠性。 + +>关注小傅哥 [bugstack.cn](https://bugstack.c) 博客，编程路书，可以学习到非常多的互联网企业使用技能，补全自己的短板！如；系统架构、开发环境、开发技术、授权框架、常用类库、工程测试、质量监控、发布部署等。 + +## 一、说说概念 + +其实简单来讲，流量录制，核心的本质就是把线上运行的应用，在有流量请求到服务接口后，把请求接口的入参和执行的结果，都保存下来。之后流量回放，则是把这些保存下来的入参信息，在开发环境/测试环境/预发环境，进行请求，之后验证请求后的结果是否与线上录制的流量结果一致。整个的这个过程，就是流量的录制和回放。 + +但实际的操作场景要比这个过程复杂，如；录制流量的操作，要无侵入代码的，要把整个调用链路，全部录制下来，而不是单个接口。同时录制的不只是对接口的操作，还有缓存、rpc、数据库（MyBatis）、es，等各类组件兼容，都能确保可正确录制到完整数据，以便在流量回放时，可以mock掉数据接口，以此只验证功能逻辑。 + +说到，逻辑和数据，这里想到了DDD架构的领域层和基础设施层，领域层（domain）专门业务功能逻辑的，而基础设置层（infrastructure）则是提供数据的。这样有了业务功能和数据获取的分离，不让核心业务逻辑又掺杂外部接口的调用，其实维护和迭代起来，是会更加容易的。 + +## 二、讲讲原理 + +为了可以无侵入式的完成系统的流量录制和流量回放，这里引入了一个 Java Agent 字节码增强技术，通过在程序启动阶段，对工程代码的方法进行埋点。这个埋点，就等同于动态的通过 class 文件写入新的代码，新的代码可以采集到方法的出入参信息，并把这些信息发送到流量录制存储方，或者执行时进行mock接口请求结果处理。 + +这部分技术方案，小傅哥于19-20年，编写了先关的技术资料。其中包括了用于处理字节码增强技术的，asm、javassist、byte-buddy 三种框架。 + +

+ +
+ +- 运行脚本后，可以查看到当前服务的运行数据信息。另外这里还有一些 JVM 基础知识，补充给大家。 + +#### 4.1.1 jvm 内存空间都有啥 + +在 Java 运行环境中，JVM（Java Virtual Machine, Java 虚拟机）是执行 Java 程序的引擎，而内存管理是 JVM 非常重要的一部分。JDK 1.8 中的 JVM 内存空间主要分为以下几个区域，每个区域都有其特定的用途： + +1. 堆（Heap）： + - 用途：堆是 JVM 中内存最大的一块，用于存储所有的对象实例和数组。几乎所有对象都在此分配内存，垃圾收集器也在这里执行。 + - 分代垃圾收集机制：堆内存被进一步划分为新生代和老年代。 + - 新生代（Young Generation）：用于存放新创建的对象。其中又分为伊甸园区（Eden Space）和两个幸存者区（Survivor Spaces，通常称为 S0 和 S1）。 + - 老年代（Old Generation）：用于存放生命周期较长的对象。 + +2. 方法区（Method Area）（在 JDK 1.8 中已被细化为元空间 Metaspace）： + - 用途：存储已被加载的类元数据、常量、静态变量等。在 JDK 1.8 中，用于取代永久代（PermGen）。 + - 元空间（Metaspace）：与永久代不同，元空间用的是本地内存而不是堆内存，这避免了 Java 中永久代容量不足导致的内存问题。 + +3. 栈（Stack）： + - 用途：每个线程创建时会分配一个栈，它用来存储局部变量表、操作数栈、动态链接、方法出口等。栈内存会自动随着方法的进出而分配和释放。 + - 特性：栈是线程私有的，每个线程都有自己的栈。 + +4. 程序计数器（Program Counter Register）： + - 用途：是一个较小的内存空间，用于指示当前线程所执行的字节码的行号。 + - 特性：它是唯一一个在 Java 虚拟机规范中没有规定任何 OutOfMemoryError 情况的区。 + +5. 本地方法栈（Native Method Stack）： + - 用途：与 Java 栈类似，但它主要用于处理本地方法（Native Method）的执行。 + - 特性：也是线程私有的，负责本地方法的调度和执行。 + +这些内存区的设计是为了支持 Java 的垃圾收集机制和多线程并发运行，确保 Java 应用程序能够高效和稳定地执行。了解这些内存区的功能和作用，可以帮助开发者优化 Java 应用的性能，并有效管理内存使用。 + +#### 4.1.2 垃圾回收算法 + +GC 核心在于通过不同的算法来高效管理内存资源。常用的 GC 算法包括： + +1. 标记-清除算法（Mark and Sweep）： + - 标记阶段：遍历所有的对象引用，标记活动的对象。 + - 清除阶段：清理掉未被标记的对象。 + - 缺点：容易造成内存碎片，因为清除后内存是不连续的。 + +2. 复制算法（Copying）： + - 将活动的对象从一块内存（From space）复制到另一块（To space），然后清理整块 From space。 + - 优点：内存分配简单，不会产生碎片。 + - 缺点：需要预留多余的内存空间实行复制。 + +3. 标记-整理算法（Mark-Compact）： + - 标记阶段：和标记-清除相似。 + - 整理阶段：将所有活动对象移到一端，处理剩余的空间为可用。 + - 减少了碎片化问题，但相比复制算法更复杂。 + +4. 分代收集算法： + - 根据对象的生命周期不同，将堆分为新生代和老年代。 + - 新生代使用复制算法，老年代使用标记-清除 或 标记-整理。 + - 优点：优化了大多数对象短命这一特性带来的效率。垃圾回收算法。 + +#### 4.1.3 垃圾收集器 + +Java 提供了多种垃圾收集器，适用于不同应用场景： + +1. Serial GC： + - 单线程收集器，非常适合单线程环境和小型应用。 + - 效率高但可能造成长时间的停顿。 + +2. Parallel GC (Throughput Collector)： + - 多线程收集器，用于最大化 CPU 吞吐量。 + - 适合后台处理任务和高效利用系统资源的场景。 + +3. CMS GC (Concurrent Mark-Sweep Collector)： + - 重点在于缩短停顿时间，适合响应时间敏感的应用。 + - 较轻量级的 GC，但处理老年代垃圾时效率不如 Parallel。 + +4. G1 GC (Garbage-First Collector)： + - 设计用于大堆，提供可预测的停顿时间。 + - 将堆划分为不同的区域（Region），针对不同老化级别进行回收。 + +5. ZGC / Shenandoah GC： + - 尝试实现低延迟垃圾回收，几乎不会造成任何长时间的停顿。 + +#### 4.1.4 code_cache (代码缓存区)、compressed_class_space (压缩类空间)、metaspace (元空间)，他们的用途是什么，有什么要注意的。 + +在 Java 虚拟机（JVM）中，非堆内存部分包括多个区域，每个区域负责存储不同种类的数据，这里重点介绍 Code Cache（代码缓存区）、Compressed Class Space（压缩类空间）和 Metaspace（元空间）的用途及注意事项。 + +##### 1. Code Cache（代码缓存区） + +用途： +- JIT 编译代码：Java 虚拟机的即时编译器（Just-In-Time Compiler，JIT）会将频繁使用的字节码编译成本地机器码，以提高运行性能。编译后的本地代码存储在代码缓存区中。 +- 性能提升：通过存储这些编译后的代码，JVM 可以避免对同一代码片段重复进行解释，从而提升执行速度。 + +注意事项： +- 内存限制：代码缓存区有固定的最大值（可通过 `-XX:ReservedCodeCacheSize` 参数配置），需要注意在长时间运行的应用程序中这个区不会被耗尽，否则可能导致性能退化。 +- 清理与优化：JVM 在启动时和运行过程中可能会执行代码缓存的清理和优化，这个过程会对性能有一定影响。 + +##### 2. Compressed Class Space（压缩类空间） + +用途： +- 存储类元数据：在开启类指针压缩的情况下（默认开启），这个空间用于存储类元数据的压缩指针，以节省内存空间。 +- 支持元空间：压缩类空间是元空间的一部分，专门用来优化类加载器的内存消耗。 + +注意事项： +- 有固定最大限制：虽然是元空间的一部分，但压缩类空间有自己的最大内存限制（默认为 1GB），可以通过 `-XX:CompressedClassSpaceSize` 参数调整。 +- 适配性告诉：32 位 JVM 不使用压缩类空间功能，64 位 JVM 在默认情况下是开启的，因其节省的内存对大型应用尤其重要。 + +##### 3. Metaspace（元空间） + +用途： +- 替换永久代：Java 8 开始，用元空间替代了永久代，用于存储类的元数据（类的结构信息、方法、字段等）。 +- 动态调整大小：与永久代不同，元空间作为物理内存的一部分，不断增长（直到达到物理内存上限），默认不设置上限，灵活性更高。 + +注意事项： +- 内存泄漏风险：尽管更灵活，但如果不加限制，糟糕的类加载策略可能导致元空间内存泄漏。在开发环境中尤其要防止过度类加载。 +- 调整与监控：可以通过 `-XX:MetaspaceSize` 和 `-XX:MaxMetaspaceSize` 进行调节，适当限制，在实际使用中密切监控。 +- 自动释放：JVM 在内存不足时会尝试回收未使用的类加载的内存，虽然一般无需手动干预，了解这方面的配置有助于优化内存使用。 + +这些部分的配置和监控是调优 JVM 的重要组成部分，适当的配置可以防止内存泄漏、排查性能瓶颈，并为应用程序的稳定性提供保障。 + +### 4.2 火焰图 + +#### 4.2.1 生成脚本 + +profiler 命令支持生成应用热点的火焰图。本质上是通过不断的采样，然后把收集到的采样结果生成火焰图。火焰图可以清楚的看到程序运行中对象的创建，这样你就可以发现那些大对虾(像)从哪来的？ + +操作过程，开启采集 `profiler start --event alloc` 等待程序执行，关闭采集 `profiler stop --format html` + +我们操作中，开启采集后，可以先执行多次的 curl-one.sh 调用接口，多产生点对象。 + +```java +profiler start --event alloc + +profiler getSamples + +profiler status + +profiler stop --format html +``` + +
+ +
+ +- 执行完成后，你会得到一个火焰图的 html 文件。之后就可以打开了。 + +#### 4.2.2 查看图表 + +
+ +
+ +1. 这里的x轴代表采样总量（也就是此刻所有执行的耗时cpu的方法）。这是注意的是x 轴并不代表时间，而是所有的调用方法合并后，按字母顺序排列。 +2. Y轴代表方法的调用栈深度，每一层都是一个方法。顶部是正在执行的方法。当然调用栈越深，火焰就越高。 +3. 鼠标可以点击的选中的每个框就代表了一个栈里的函数，其宽度可以直接理解为CPU时间占比（其实是采样的数量以及与采样总量的占比）。 +4. 那么，也就是说占比比较宽的框就表示：a.该函数运行时间较长（单次时间长）b.被调用次数较多.（调用频率高）进而被采样的次数比较多，占用的CPU时间多。 +4. 这样你就知道了是哪里在创建大对像。比如一些数据库对象，缓存对象等，特别大，又耗时，一下就监控出来了。 + +> Arthas 提供的功能还有很多，不过咱们要换个更加舒服的方式使用了。如下。 + +## 五、IDEA Plugin Arthas + +### 1. 安装插件 + +
+ +
+ +### 2. 使用插件 + +这些命令你都可以通过 Arthas IDEA Plugin 插件复制出来使用。 + +- [monitor](https://arthas.aliyun.com/doc/monitor.html) - 方法执行监控 +- [stack](https://arthas.aliyun.com/doc/stack.html) - 输出当前方法被调用的调用路径 +- [trace](https://arthas.aliyun.com/doc/trace.html) - 方法内部调用路径，并输出方法路径上的每个节点上耗时 +- [tt](https://arthas.aliyun.com/doc/tt.html) - 方法执行数据的时空隧道，记录下指定方法每次调用的入参和返回信息，并能对这些不同的时间下调用进行观测 +- [watch](https://arthas.aliyun.com/doc/watch.html) - 方法执行数据观测 + +更多命令 [https://arthas.aliyun.com/doc/commands.html](https://arthas.aliyun.com/doc/commands.html) + +#### 2.1 复制命令 + +
+ +
+ +#### 2.2 使用命令 + +
+ +
+ +- 如图你就可以监控到方法的运行信息了。 + +### 3. 其他命令 + +#### 3.1 查看代码 + +
+ +
+ +- 线上运行的代码，不确定是否是最新的，那么这样就可以一步获取到并对比。 + +#### 3.2 接口参数 + +
+ +
+ +- 有时候预发验证服务，因为不会打印所有的服务接口出入参信息，但遇到问题不好排查。 +- 那么使用 Arthas 插件，就可以直接获取到接口的出入参了，方便排查问题。 + +> 其他更多命令可以通过官网的命令提示和插件一起使用验证了。 diff --git a/docs/md/road-map/buddy.md b/docs/md/road-map/buddy.md new file mode 100644 index 000000000..0902d75f4 --- /dev/null +++ b/docs/md/road-map/buddy.md @@ -0,0 +1,213 @@ +--- +title: Docker 镜像构建 - Buddy +lock: need +--- + +# Docker 镜像构建 - Buddy + +作者：小傅哥 +

+ +
+ +## 三、添加项目 + +地址：[https://app.buddy.works/](https://app.buddy.works/) + +
+ +
+ +- 首先，需要在首页选择【添加项目】，并根据步骤选择你的仓库。 +- 之后，这里小傅哥选择了专用服务器，填写我的Gitcode仓库地址。「Gitcode的账密就是CSDN的账密」 +- 提示：你可以Fork代码到自己的仓库进行使用 [https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-jenkins](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-jenkins) + +## 四、添加流水线 + +流水线，就跟它的名字一样，用于构建项目所需的一条链路流程。如；Maven 构建、镜像打包&发布、SSH 基本驱动容器启动。也可以是 Maven 构建后直接通过 SFTP 把Jar传递到 Linux 服务器，在通过 SSH 链接执行 Shell 脚本完成 Jar 的镜像打包和部署。 + +所以，接下来我们先来完成一个流水线的最基础 Maven 构建，之后再分别添加不同类型的流水线操作。「Buddy提供了各种插件，你可以分别组合他们进行使用，完成项目的部署。」 + +注意📢：流水线上的节点，你可以在右侧的绿色按钮进行关闭，只执行你需要的节点。比如现在你已经知道 Maven 构建成功了，只需要推送镜像。那么可以去掉上一个节点，这样速度更快。 + +
+ +
+ +### 1. Docker 流水线 + +- 说明：这条流水线的步骤为；Maven 构建、构建Docker镜像、推送Docker镜像、SSH连接服务器拉取镜像和部署。 +- 步骤：你可以点击**小加号+**，选择添加不同的流水线节点。 + +
+ +
+ +#### 1.1 构建Docker镜像 + +
+ +
+ +#### 1.2 推送Docker镜像 + +
+ +
+ +- 注意📢：你已经在 [https://hub.docker.com/](https://hub.docker.com/) 创建了自己的镜像，比如我的是；[fuzhengwei/xfg-dev-tech-jenkins](fuzhengwei/xfg-dev-tech-jenkins) 这样你的镜像才能PUSH进去。 + +#### 1.3 SSH连接服务器拉取镜像和部署 + +
+ +
+ +```shell +# 先删除之前的容器和镜像文件 +if [ "$(docker ps -a | grep xfg-dev-tech-jenkins)" ]; then +docker stop xfg-dev-tech-jenkins +docker rm xfg-dev-tech-jenkins +fi +if [ "$(docker images -q xfg-dev-tech-jenkins)" ]; then +docker rmi xfg-dev-tech-jenkins +fi + +docker pull fuzhengwei/xfg-dev-tech-jenkins:2.0 +docker run -itd -p 8091:8091 --name xfg-dev-tech-jenkins fuzhengwei/xfg-dev-tech-jenkins:2.0 +``` + +- 注意：拉取镜像的速度取决于你的服务器所在的地区，有时候会拉取失败。如果你的云服务器拉取镜像总是失败❌，可以选择第二个方式 SSH 流水线。它不需要走到DockerHub，能减少网络操作。 + +### 2. SSH 流水线 + +说明：这条流水线的步骤为；Maven构建、通过 SFTP 上传构建的Jar到云服务器。之后通过 SSH 执行 Shell 脚本，在云服务器创建出 Dockerfile 「注意路径」，这样 Docker镜像就直接在云服务器的 Docker上了，不需要在通过 DockerHub 拉取镜像。最后通过 SSH 执行 Shell 脚本启动服务即可。 + +
+ +
+ +#### 2.1 SFTP 上传Jar + +
+ +
+ +- 配置好传输地址、目标地址，通过 SSH 连接云服务器进行传输。 +- `/dev-ops`这个是云服务器的地址，你可以自己定义任何的地址。如果文件夹不存在，也会自动创建。 + +#### 2.2 创建Dockerfile + +
+ +
+ +```shell +#!/bin/bash + +cd /dev-ops + +# 定义Dockerfile的路径 +DOCKERFILE_PATH="https://bugstack.cn/images/roadmap/tutorial/Dockerfile" + +# 创建Dockerfile并写入内容 +cat > $DOCKERFILE_PATH << 'EOF' +# 基础镜像 openjdk:8-jre-slim +FROM openjdk:8-jre-slim + +# 作者 +MAINTAINER xiaofuge + +# 配置 +ENV PARAMS="" + +# 时区 +ENV TZ=PRC +RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone + +# 添加应用 +ADD target/xfg-dev-tech-app.jar /xfg-dev-tech-app.jar + +## 在镜像运行为容器后执行的命令 +ENTRYPOINT ["sh","-c","java -jar $JAVA_OPTS /xfg-dev-tech-app.jar $PARAMS"] +EOF + +echo "Dockerfile has been created." +``` + +- 因为我们把 Maven 构建的 Jar 传到了云服务器。所以需要在 Jar 对应的目录下，创建出 Dockerfile 这样就可以通过执行 Dockerfile 完成镜像的构建了。 +- 此外如果你的代码库配置有 Dockerfile，也可以通过 SFTP 的方式把 Dockerfile 上传到云服务器对应 Jar 的位置。「我只是帮你选择了一个更稳的方式」 + +#### 2.3 运行服务 + +
+ +
+ +```shell +# 先删除之前的容器和镜像文件 +if [ "$(docker ps -a | grep xfg-dev-tech-jenkins)" ]; then +docker stop xfg-dev-tech-jenkins +docker rm xfg-dev-tech-jenkins +fi +if [ "$(docker images -q xfg-dev-tech-jenkins)" ]; then +docker rmi xfg-dev-tech-jenkins +fi + +cd /dev-ops +docker build -t xiaofuge/xfg-dev-tech-jenkins:1.3 . +docker run -itd -p 8091:8091 --name xfg-dev-tech-jenkins xiaofuge/xfg-dev-tech-jenkins:1.3 +``` + +- `cd /dev-ops`进入到文件路径。之后构建镜像和部署。 + +## 五、运行流水线 + +

+ +
+ +canal ，译为水道/管道/沟渠，主要用途是基于 MySQL 数据库增量日志解析，提供增量数据订阅和消费。 + +早期阿里巴巴因为杭州和美国双机房部署，存在跨机房同步的业务需求，实现方式主要是基于业务 trigger 获取增量变更。从 2010 年开始，业务逐步尝试数据库日志解析获取增量变更进行同步，由此衍生出了大量的数据库增量订阅和消费业务。 + +它的工作原理是，canal 模拟 MySQL slave 的交互协议，伪装自己为 MySQL slave ，向 MySQL master 发送dump 协议。在 MySQL master 收到 dump 请求，开始推送 binary log 给 slave (即 canal ) 这样 canal 再解析 binary log （binlog）进行配置分发，同步到 Elasticsearch 等系统中进行使用。 + +那么有了 canal 就可以把分库分表的数据同步到 Elasticsearch，提供汇总查询和聚合操作，也就不需要把轮训每个分库分表数据了。 + +## 二、测试预期 + +本文的案例会把MySQL，2库4表的数据，通过 Sharding 分库分表写入数据后，同步到 Elasticsearch。分库分表如下（环境安装中会自动安装数据库和设置库表）； + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +本文的宗旨在于通过简单干净实践的方式教会读者，如何实现一个分库分表的路由组件。这里包括；AOP、路由散列算法、动态数据源切换等相关知识。 + +本文涉及的工程： + +- xfg-dev-tech-db-router：[https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-db-router](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-db-router) + +## 一、需求分析 + +`如果要做一个数据库路由，都需要做什么技术点？` + +首先我们要知道为什么要用分库分表，其实就是由于业务体量较大，数据增长较快，所以需要把用户数据拆分到不同的库表中去，减轻数据库压力。 + +分库分表操作主要有垂直拆分和水平拆分： +- 垂直拆分：指按照业务将表进行分类，分布到不同的数据库上，这样也就将数据的压力分担到不同的库上面。最终一个数据库由很多表的构成，每个表对应着不同的业务，也就是专库专用。 +- 水平拆分：如果垂直拆分后遇到单机瓶颈，可以使用水平拆分。相对于垂直拆分的区别是：垂直拆分是把不同的表拆到不同的数据库中，而水平拆分是把同一个表拆到不同的数据库中。如：user_001、user_002 + +而本章节我们要实现的也是水平拆分的路由设计，如图 1-1 + +![图 1-1](https://bugstack.cn/assets/images/middleware/blog-4-1.png) + +那么，这样的一个数据库路由设计要包括哪些技术知识点呢？ + +- 是关于 AOP 切面拦截的使用，这是因为需要给使用数据库路由的方法做上标记，便于处理分库分表逻辑。 +- 数据源的切换操作，既然有分库那么就会涉及在多个数据源间进行链接切换，以便把数据分配给不同的数据库。 +- 数据库表寻址操作，一条数据分配到哪个数据库，哪张表，都需要进行索引计算。在方法调用的过程中最终通过 ThreadLocal 记录。 +- 为了能让数据均匀的分配到不同的库表中去，还需要考虑如何进行数据散列的操作，不能分库分表后，让数据都集中在某个库的某个表，这样就失去了分库分表的意义。 + +综上，可以看到在数据库和表的数据结构下完成数据存放，我需要用到的技术包括：`AOP`、`数据源切换`、`散列算法`、`哈希寻址`、`ThreadLoca`l以及`SpringBoot的Starter开发方式`等技术。而像`哈希散列`、`寻址`、`数据存放`，其实这样的技术与 HashMap 有太多相似之处，**那么学完源码造火箭的机会来了** 如果你有过深入分析和学习过 HashMap 源码、Spring 源码、中间件开发，那么在设计这样的数据库路由组件时一定会有很多思路的出来。*接下来我们一起尝试下从源码学习到造火箭！* + +## 二、技术调研 + +在 JDK 源码中，包含的数据结构设计有：数组、链表、队列、栈、红黑树，具体的实现有 ArrayList、LinkedList、Queue、Stack，而这些在数据存放都是顺序存储，并没有用到哈希索引的方式进行处理。而 HashMap、ThreadLocal，两个功能则用了哈希索引、散列算法以及在数据膨胀时候的拉链寻址和开放寻址，所以我们要分析和借鉴的也会集中在这两个功能上。 + +### 1.

+} +``` + +- **数据结构**：哈希桶数组 + 链表 + 红黑树 +- **散列算法**：扰动函数、哈希索引，可以让数据更加散列的分布 +- **寻址方式**：通过拉链寻址的方式解决数据碰撞，数据存放时会进行索引地址，遇到碰撞产生数据链表，在一定容量超过8个元素进行扩容或者树化。 +- **学到什么**：可以把散列算法、寻址方式都运用到数据库路由的设计实现中，还有整个数组+链表的方式其实库+表的方式也有类似之处。 + +## 三、设计实现 + +### 1. 定义路由注解 + +**定义** + +```java +@Documented +@Retention(RetentionPolicy.RUNTIME) +@Target({ElementType.TYPE, ElementType.METHOD}) +public @interface DBRouter { + + String key() default ""; + +} +``` + +**使用** + +```java +@Mapper +public interface IUserDao { + + @DBRouter(key = "userId") + User queryUserInfoByUserId(User req); + + @DBRouter(key = "userId") + void insertUser(User req); + +} +``` + +- 首先我们需要自定义一个注解，用于放置在需要被数据库路由的方法上。 +- 它的使用方式是通过方法配置注解，就可以被我们指定的 AOP 切面进行拦截，拦截后进行相应的数据库路由计算和判断，并切换到相应的操作数据源上。 + +### 2. 解析路由配置 + +![](https://bugstack.cn/assets/images/middleware/blog-4-4.png) + +- 以上就是我们实现完数据库路由组件后的一个数据源配置，在分库分表下的数据源使用中，都需要支持多数据源的信息配置，这样才能满足不同需求的扩展。 +- 对于这种自定义较大的信息配置，就需要使用到 `org.springframework.context.EnvironmentAware` 接口，来获取配置文件并提取需要的配置信息。 + +**数据源配置提取** + +```java +@Override +public void setEnvironment(Environment environment) { + String prefix = "router.jdbc.datasource."; + + dbCount = Integer.valueOf(environment.getProperty(prefix + "dbCount")); + tbCount = Integer.valueOf(environment.getProperty(prefix + "tbCount")); + + String dataSources = environment.getProperty(prefix + "list"); + for (String dbInfo : dataSources.split(",")) { + Map dataSourceProps = PropertyUtil.handle(environment, prefix + dbInfo, Map.class); + dataSourceMap.put(dbInfo, dataSourceProps); + } +} +``` + +- prefix，是数据源配置的开头信息，你可以自定义需要的开头内容。 +- dbCount、tbCount、dataSources、dataSourceProps，都是对配置信息的提取，并存放到 dataSourceMap 中便于后续使用。 + +### 3. 数据源切换 + +在结合 SpringBoot 开发的 Starter 中，需要提供一个 DataSource 的实例化对象，那么这个对象我们就放在 DataSourceAutoConfig 来实现，并且这里提供的数据源是可以动态变换的，也就是支持动态切换数据源。 + +**创建数据源** + +```java +@Bean +public DataSource dataSource() { + // 创建数据源 + Map targetDataSources = new HashMap<>(); + for (String dbInfo : dataSourceMap.keySet()) { + Map objMap = dataSourceMap.get(dbInfo); + targetDataSources.put(dbInfo, new DriverManagerDataSource(objMap.get("url").toString(), objMap.get("username").toString(), objMap.get("password").toString())); + } + + // 设置数据源 + DynamicDataSource dynamicDataSource = new DynamicDataSource(); + dynamicDataSource.setTargetDataSources(targetDataSources); + return dynamicDataSource; +} +``` + +- 这里是一个简化的创建案例，把基于从配置信息中读取到的数据源信息，进行实例化创建。 +- 数据源创建完成后存放到 `DynamicDataSource` 中，它是一个继承了 AbstractRoutingDataSource 的实现类，这个类里可以存放和读取相应的具体调用的数据源信息。 + +### 4. 切面拦截 + +在 AOP 的切面拦截中需要完成；数据库路由计算、扰动函数加强散列、计算库表索引、设置到 ThreadLocal 传递数据源，整体案例代码如下： + +```java +@Around("aopPoint() && @annotation(dbRouter)") +public Object doRouter(ProceedingJoinPoint jp, DBRouter dbRouter) throws Throwable { + String dbKey = dbRouter.key(); + if (StringUtils.isBlank(dbKey)) throw new RuntimeException("annotation DBRouter key is null！"); + + // 计算路由 + String dbKeyAttr = getAttrValue(dbKey, jp.getArgs()); + int size = dbRouterConfig.getDbCount() * dbRouterConfig.getTbCount(); + + // 扰动函数 + int idx = (size - 1) & (dbKeyAttr.hashCode() ^ (dbKeyAttr.hashCode() >>> 16)); + + // 库表索引 + int dbIdx = idx / dbRouterConfig.getTbCount() + 1; + int tbIdx = idx - dbRouterConfig.getTbCount() * (dbIdx - 1); + + // 设置到 ThreadLocal + DBContextHolder.setDBKey(String.format("%02d", dbIdx)); + DBContextHolder.setTBKey(String.format("%02d", tbIdx)); + logger.info("数据库路由 method：{} dbIdx：{} tbIdx：{}", getMethod(jp).getName(), dbIdx, tbIdx); + + // 返回结果 + try { + return jp.proceed(); + } finally { + DBContextHolder.clearDBKey(); + DBContextHolder.clearTBKey(); + } +} +``` + +- 简化的核心逻辑实现代码如上，首先我们提取了库表乘积的数量，把它当成 HashMap 一样的长度进行使用。 +- 接下来使用和 HashMap 一样的扰动函数逻辑，让数据分散的更加散列。 +- 当计算完总长度上的一个索引位置后，还需要把这个位置折算到库表中，看看总体长度的索引因为落到哪个库哪个表。 +- 最后是把这个计算的索引信息存放到 ThreadLocal 中，用于传递在方法调用过程中可以提取到索引信息。 + +## 四. 测试验证 + +### 1. 库表创建 + +```java +create database `bugstack_01`;

+ +
+ +**刚入行，直接就开大吗？** + +在我最早接触编程的时候，还是9大内置对象，servlet、jsp、前端也是刚接触《锋利的JQuery》的时代。甚至很多流程代码都堆到了 jsp 页面，后端也就是连库做 CRUD 操作。多好的时代，学一点东西，就能上班赚钱了。现在要学的可就多了，仅专业技能部分，都能在写满简历 1/3 篇幅了！ + +但没办法，人嘛，总是要向钱低头的，向前！毕竟，互联网公司都是飞速迭代发展的，所以，要想混个能在群里喊【收到、收到】的资格，也得加倍学习。 + +所以，小傅哥就给大家分享下，关于系统分层架构的演进过程，看看这东西是怎么从简简单单变得复复杂杂的。 + +## 一、单层架构 + +单层架构并不算一个规范的架构定义，只是在早期 MVC 三层架构（模型、试图、控制器）还没有那么普及，以及国内开发的项目程序还没有那么规范的时候，用于快速搭建简单网页功能的一种设计。 + +
+ +
+ +所有的分层结构的设计，都是以承接功能实现诉求为目的，这一阶段仅仅是完成网页的数据展示，也几乎没有用户交互。所以，很多时候是有多少个页面，就有多少个 Controller 提供接口，以及编写好调用数据库查询数据的操作。 + +## 二、三层架构 + +1978年，MVC模式最早由 [Trygve Reenskaug](https://zh.wikipedia.org/w/index.php?title=Trygve_Reenskaug&action=edit&redlink=1) 提出，**MVC模式**的目的是实现一种动态的程序设计，使后续对程序的修改和扩展简化，并且使程序某一部分的重复利用成为可能。除此之外，此模式透过对复杂度的简化，使程序结构更加直观。 + +
+ +
+ +- 当 Controller 里承载业务功能逐步变多以后，我们开始思考怎么把这些东西分区存放。那么可以把各类对象归类到一个文件夹，之后把 Controller 里的复杂逻辑拆分为一个个原子的 service 服务，让 Controller 的接口负责调用。 +- 目前的分层架构，就可以适合开发一些复杂逻辑的场景诉求了，不过整体系统的承载量仍然是偏弱一些的。 + +## 三、三层架构（分布式） + +3层架构出现的很早，其实本身的设计没有考虑复杂的分布式场景。在从三层架构演变到可以支持分布式架构的时候，是没有一个统一的标准规范的，更多的各个公司里自己直接从旧工程里添加了新的 module 分层模块。 + +
+ +
+ +- 首先，一个分布式架构要，对接 rpc、提供 rpc、消费 mq、生产 mq，还要做定时任务（最终一致性补偿），单一个 rpc 的使用，就需要在程序定义出一个 export 层，要打包对外的服务接口，让使用方式引入使用。关于为什么需要这样的方式，可以在 [bugstack.cn](https://bugstack.cn/md/road-map/dubbo.html) 编程路书中，开发技术部分 dubbo 学习。 +- 之后，原本的 MVC 三层结构就不够用了。只要添加上，export、rpc 这样的分层，原本 service 直接处理数据库的操作，也要考虑拆分出来。可能这部分每个公司还不一样，其实即使一个公司，不同组，也是有很大的差异。这个也是目前互联网公司中的项目里的一个现状问题。 +- 思考，现在的工程模型结构其实很杂，装填了太多的东西进去了。除此之外，因为都是原子化编写，没有在做分区。一个系统里 service 都有上千个类，每个类里又有上千行代码。在坐的各位，应该都会在这些屎山中赚钱。 + +## 四、四层架构 + +DDD 是思想，六边形/菱形/整洁架构是分层，DDD 通过建模思想，指导我们以从用例图（use case diagram）出发，与产品、研发、测试一起在一个规范下，脑暴建模。在这个过程中，以结果为导向，分析出可能存在的领域服务。这些领域服务，如登录完成，下单完成，支付完成，收货完成，根据结果态，分析支撑这样的服务所需的对象（实体）、流程、规则等。这样我们可以更加清晰的构建一套系统。 + +而，六边形（常用的）架构，则是用于承接 DDD 领域驱动设计对系统分析后的编码实现。六边形可以说是专门为 DDD 做的配套架构，虽然也可以用 MVC 来编写，但这样是会失去面向对象设计和编码的优势，让代码逻辑混乱在一起。所以，这也是各个互联网公司开始往 DDD 架构切换的目的。这件事，我已经干了好几年了！ + +
+ +
+ +- 首先，六边形架构，以 DDD 领域驱动实际为指引，为 domai 层，设计充血模型结构，如；登录、下单、支付，在每个模块下，包含完整的服务、模型、适配。适配的目的是这个领域里所需的数据，都通过适配的方式从外部调用进来，比如；数据库、缓存、接口等。这是一种 ACL 防腐设计，将来外部的接口变化了，也不会影响我们的领域服务，只要按照领域服务的适配标准提供即可。 +- 之后，围绕着领域 domain 开始，需要啥就让外部的基础设施层实现领域层的接口来提供。而接口要提供啥能力，就调用 case 编排 domain 层，或则简单的由 domain 层直接提供也可以。 +- 最后，也就是 trigger 触发器，我们把接口、任务、mq等都理解为一种触发，之后让 trigger 调用 case 层。case 或者 domain 的目的，就是分摊 trigger 以前 Controller 编写逻辑代码的压力。让 trigger 只是负责对外逻辑的封装，错误码，异常即可。 + +综上，就是关于架构分层的一个演进过程，现在还有 AI 的加入，AI 也会逐步成为整个工程架构中的一块。关于这部分的架构设计，与业务工程的结合，小傅哥也会在 bugstack.cn 博客中陆续更新。 + diff --git a/docs/md/road-map/ddd-guide-01.md b/docs/md/road-map/ddd-guide-01.md new file mode 100755 index 000000000..1b8868b28 --- /dev/null +++ b/docs/md/road-map/ddd-guide-01.md @@ -0,0 +1,186 @@ +--- +title: DDD 概念理论 +lock: need +--- + +# DDD 是什么？—— 你以前只会用 Service + 贫血模型！ + +作者：小傅哥 +
博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主小傅哥。 + +DDD 是什么，这应该是每个想使用 DDD 开发项目的研发伙伴，遇到的第一个疑问，只有搞清楚它到底是什么才好上手使用。而 DDD 既不是 MVC 一样的工程结构，也不能直接等同于微服务架构，更不是一种设计模式。 + +## 1. DDD 是什么 + +那 DDD 是什么呢？来自于维基百科的一段定义：["Domain-driven design (DDD) is a major software design approach. "](https://en.wikipedia.org/wiki/Domain-driven_design)，DDD 是一种软件设计方法。也就是说 DDD 是指导我们做软件工程设计的一种手段，它提供了用切割工程模型的各类技巧，如；领域、界限上下文、实体、值对象、聚合、工厂、仓储等。通过 DDD 的指导思想，我们可以在前期投入更多的时间，更加合理的规划出可持续迭代的工程设计。 + +在 DDD 中有一套共识的工程两阶段设计手段，包括；战略设计、战术设计。 + +- **战略设计**，主要以应对复杂的业务需求，通过抽象、分治的过程，合理的拆分为独立的多个微服务，从而分而治之。与之评价拆分的是否合理，则是在需求开发上线时候，是否每次都大量操作多个微服务开发和上线。这样的战略设计是一种失败的微服务单体设计。所以少数几个中等规模的单体应用，周围环绕着一个服务生态系统，这更有意义。[你实际上并没有构建微服务 @贾斯汀·埃瑟里奇](https://www.simplethread.com/youre-not-actually-building-microservices/) + +- **战术设计**，在这个范畴下，主要以讨论如何基于面向对象思维，运用领域模型来表达业务概念。通常在不做领域模型设计的架构，也就是通常映射到 MVC 三层架构下，`Service + 数据模型`的开发模式，会让 Service 扁平的、大量的，平铺出非常复杂的业务逻辑代码。再加上行为对象与功能逻辑的分离，贫血模型的开发方式，让行为对象的不断交叉使用，也是让系统不断增加复杂度，并到难以维护的根因。所以这一阶段要设计每一个可以表达领域概念的模型，并运用实体、聚合、领域服务来承载。 + +## 2. DDD 的概念 + +什么是充血模型？领域内都包括什么？实体、聚合、值对象，有什么区别？这样一些"为什么"的概念，也是战术设计过程中非常重要的知识项。搞清楚它们才能做 DDD 设计。 + +### 2.1 充血模型 + +**充血模型**，指将对象的属性信息与行为逻辑聚合到一个类中，常用的手段如：在对象内提供属于当前对象的`信息校验`、`拼装缓存Key`、`不含服务接口调用的逻辑处理`等。 + +
+ +
+ +- 这样的方式可以在使用一个对象时，就顺便拿到这个对象的提供的一系列方法信息，所有使用对象的逻辑方法，都不需要自己再次处理同类逻辑。 +- 但不要只是把充血模型，仅限于一个类的设计和一个类内的方法设计。充血还可以是整个包结构，一个包下包括了用于实现此包 Service 服务所需的各类零部件（模型、仓储、工厂），也可以被看做充血模型。 +- 同时我们还会再一个同类的类下，提供对应的内部类，如用户实名，包括了，通信类、实名卡、银行卡、四要素等。它们都被写进到一个用户类下的内部子类，这样在代码编写中也会清晰的看到子类的所属信息，更容易理解代码逻辑，也便于维护迭代。 + +### 2.2 领域模型 + +**领域模型**，指特定业务领域内，业务规则、策略以及业务流程的抽象和封装。在设计手段上，通过风暴模型拆分领域模块，形成界限上下文。最大的区别在于把原有的`众多 Service + 数据模型`的方式，拆分为独立的有边界的领域模块。每个领域内创建自身所属的；领域对象（实体、聚合、值对象）、仓储服务(DAO 操作)、工厂、端口适配器Port（调用外部接口的手段）等。 + +那么，现在这里有几个概念：领域服务、领域对象、仓储定义、事件消息、端口适配器。我们先来看他们是怎么从贫血模型演变过来的，在细分讲解每个概念。 + +
+ +
+ +- 在原本的 Service + 贫血的数据模型开发指导下，Service 串联调用每一个功能模块。这些基础设施（对象、方法、接口）是被相互调用的。这也是因为贫血模型并没有面向对象的设计，所有的需求开发只有详细设计。 +- 换到充血模型下，现在我们以一个领域功能为聚合，拆分一个领域内所需的 Service 为领域服务，VO、Req、Res 重新设计为领域对象，DAO、Redis 等持久化操作为仓储等。举例：一套账户服务中的，授信认证、开户、提额降额等，每一个都是一个独立的领域，在每个独立的领域内，创建自身领域所需的各项信息。 +- 领域模型还有一个特点，它自身只关注业务功能实现，不与外部任何接口和服务直连。如；不会直接调用 DAO 操作库，也不会调用缓存操作 Redis，更不会直接引入 RPC 连接其他微服务。而是通过仓库和端口适配器，定义调用外部数据的含有出入参对象的接口标准，让基础设施层做具体的调用实现——通过这样的方式让领域只关心业务实现，同时做好防腐。 + +### 2.3 实体、聚合、值对象 + +原本在贫血模型下的开发，常常是不会特别在意一个方法的出入参对象的，也经常是很多个服务共用一个VO对象作为入参，只要这个对象能把我需要的属性信息带进来就可以了。 + +但在 DDD 的领域模型设计下，领域对象的设计是非常面向对象的。而且在整个风暴事件的四色建模过程也是在以领域对象为驱动进行的。 + +实体、聚合、值对象，三者位于每个领域下的领域对象内，服务于领域内的领域服务。三个对象定义具体如下： + +

+ +1. 胳膊、腿、身体，都是实体对象，和这个人生命有关。 +2. 帽子、手套、裤衩，都是值对象，是这个人穿戴的，不具有生命属性。 +3. 聚合，就是要写库一个事务，一次形成，可以聚合。把胳膊、腿、身体，放一块，一起让数据库执行事务。 + +> **实体** + +是依托于持久化层数据以领域服务功能目标为指导设计的领域对象。持久化PO对象是原子类对象，不具有业务语义，而实体对象是具有业务语义且有唯一标识的对象，跟随于领域服务方法的全生命周期对象。如：用户PO持久化对象，会涵盖，用户的开户实体、授信实体、额度实体对象。也包括如商品下单时候的购物车实体对象。这个对象也通常是领域服务方法的入参对象。 + +- 概念：实体 = 唯一标识 + 状态属性 + 行为动作（功能），是DDD中的一个基本构建块，它代表了具有唯一标识的领域对象。实体不仅仅包含数据（状态属性），还包含了相关的行为（功能），并且它的标识在整个生命周期中保持不变。 +- 特征： + - **唯一标识**：实体具有一个可以区分其他实体的标识符。这个标识符可以是一个ID、一个复合键或者是一个自然键，关键是它能够唯一地标识实体实例。 + - **领域标识**：实体的标识通常来源于业务领域，例如用户ID、订单ID等。这些标识符在业务上有特定的含义，并且在系统中是唯一的。 + - **委派标识**：在某些情况下，实体的标识可能是由ORM（对象关系映射）框架自动生成的，如数据库中的自增主键。这种标识符虽然可以唯一标识实体，但它并不直接来源于业务领域。 +- 用途： + - **表达业务概念**：实体用于在软件中表达具体的业务概念，如用户、订单、交易等。通过实体的属性和行为，可以描述这些业务对象的特征和能力。 + - **封装业务逻辑**：实体不仅仅承载数据，还封装了业务规则和逻辑。这些逻辑包括验证数据的有效性、执行业务规则、计算属性值等。这样做的目的是保证业务逻辑的集中和一致性。 + - **保持数据一致性**：实体负责维护自身的状态和数据一致性。它确保自己的属性和关联关系在任何时候都是正确和完整的，从而避免数据的不一致性。 +- 实现手段： + - **定义实体类**：在代码中定义一个类，该类包含实体的属性、构造函数、方法等。 + - **实现唯一标识**：为实体类提供一个唯一标识的属性，如ID，并确保在实体的生命周期中这个标识保持不变。 + - **封装行为**：在实体类中实现业务逻辑的方法，这些方法可以操作实体的状态，并执行相关的业务规则。 + - **使用ORM框架**：利用ORM框架将实体映射到数据库表中，这样可以简化数据持久化的操作。 + - **实现领域服务**：对于跨实体或跨聚合的操作，可以实现领域服务来处理这些操作，而不是在实体中直接实现。 + - **使用领域事件**：当实体的状态发生变化时，可以发布领域事件，这样可以通知其他部分的系统进行相应的处理。 + +> **值对象** + +这个对象在领域服务方法的生命周期过程内是不可变对象，也没有唯一标识。它通常是配合实体对象使用。如为实体对象提供对象属性值的描述，比如：一个公司雇员的级别值对象，一个下单的商品收货的四级地址信息对象。所以在开发值对象的时候，通常不会提供 setter 方法，而是提供构造函数或者 Builder 方法来实例化对象。这个对象通常不会独立作为方法的入参对象，但做可以独立作为出参对象使用。 + +- 概念：值对象是由一组属性组成的，它们共同描述了一个领域概念。与实体（Entity）不同，值对象不需要有一个唯一的标识符来区分它们。值对象通常是不可变的，这意味着一旦创建，它们的状态就不应该改变。 +- 特征： + - **不可变性（Immutability）**：值对象一旦被创建，它的状态就不应该发生变化。这有助于保证领域模型的一致性和线程安全性。 + - **等价性（Equality）**：值对象的等价性不是基于身份或引用，而是基于对象的属性值。如果两个值对象的所有属性值都相等，那么这两个对象就被认为是等价的。 + - **替换性（Replaceability）**：由于值对象是不可变的，任何需要改变值对象的操作都会导致创建一个新的值对象实例，而不是修改现有的实例。 + - **侧重于描述事物的状态**：值对象通常用来描述事物的状态，而不是事物的唯一身份。 + - **可复用性（Reusability）**：值对象可以在不同的领域实体或其他值对象中重复使用。 +- 用途： + - 金额和货币（如价格、工资、费用等） + - 度量和数据（如重量、长度、体积等） + - 范围或区间（如日期范围、温度区间等） + - 复杂的数学模型（如坐标、向量等） + - 任何其他需要封装的属性集合 +- 实现手段： + - **定义不可变类**：确保类的所有属性都是私有的，并且只能通过构造函数来设置。 + - **重写equals和hashCode方法**：这样可以确保值对象的等价性是基于它们的属性值，而不是对象的引用。 + - **提供只读访问器**：只提供获取属性值的方法，不提供修改属性值的方法。 + - **使用工厂方法或构造函数创建实例**：这有助于确保值对象的有效性和一致性。 + - **考虑序列化支持**：如果值对象需要在网络上传输或存储到数据库中，需要提供序列化和反序列化的支持。 + +> **聚合** + +当你对数据库的操作需要使用到多个实体时，可以创建聚合对象。一个聚合对象，代表着一个数据库事务，具有事务一致性。聚合中的实体可以由聚合提供创建操作，实体也被称为聚合根对象。一个订单的聚合，会涵盖：下单用户实体对象、订单实体、订单明细实体和订单收货四级地址值对象。而那个作为入参的购物车实体对象，已经被转换为实体对象了。—— 聚合内事务一致性，聚合外最终一致性。 + +- 概念：聚合是领域模型中的一个关键概念，它是一组具有内聚性的相关对象的集合，这些对象一起工作以执行某些业务规则或操作。聚合定义了一组对象的边界，这些对象可以被视为一个单一的单元进行处理。 +- 特征： + - **一致性边界**：聚合确保其内部对象的状态变化是一致的。当对聚合内的对象进行操作时，这些操作必须保持聚合内所有对象的一致性。 + - **根实体**：每个聚合都有一个根实体（Aggregate Root），它是聚合的入口点。根实体拥有一个全局唯一的标识符，其他对象通过根实体与聚合交互。 + - **事务边界**：聚合也定义了事务的边界。在聚合内部，所有的变更操作应该是原子的，即它们要么全部成功，要么全部失败，以此来保证数据的一致性。 +- 用途： + 1. **封装业务逻辑**：聚合通过将相关的对象和操作封装在一起，提供了一个清晰的业务逻辑模型，有助于业务规则的实施和维护。 + 2. **保证一致性**：聚合确保内部状态的一致性，通过定义清晰的边界和规则，聚合可以在内部强制执行业务规则，从而保证数据的一致性。 + 3. **简化复杂性**：聚合通过组织相关的对象，简化了领域模型的复杂性。这有助于开发者更好地理解和扩展系统。 +- 实现手段： + - **定义聚合根**：选择合适的聚合根是实现聚合的第一步。聚合根应该是能够代表整个聚合的实体，并且拥有唯一标识。 + - **限制访问路径**：只能通过聚合根来修改聚合内的对象，不允许直接修改聚合内部对象的状态，以此来维护边界和一致性。 + - **设计事务策略**：在聚合内部实现事务一致性，确保操作要么全部完成，要么全部回滚。对于聚合之间的交互，可以采用领域事件或其他机制来实现最终一致性。 + - **封装业务规则**：在聚合内部实现业务规则和逻辑，确保所有的业务操作都遵循这些规则。 + - **持久化**：聚合根通常与数据持久化层交互，以保存聚合的状态。这通常涉及到对象-关系映射（ORM）或其他数据映射技术。 + + +### 2.4 仓储和适配器 + +在 DDD 的设计方法中，领域层做到了只关心领域服务实现。最能体现这样设计的就是仓库和适配器的设计。通常在 `Service + 数据模型`的设计中，会在 Service 中引入 Redis、RPC、配置中心等各类其他外部服务。但在 DDD 中，通过仓储和适配器以及基础设施层的定义，解耦了这部分内容。 + +
+ +
+ +- 特征： + - 封装持久化操作：Repository负责封装所有与数据源交互的操作，如创建、读取、更新和删除（CRUD）操作。这样，领域层的代码就可以避免直接处理数据库或其他存储机制的复杂性。 + - 领域对象的集合管理：Repository通常被视为领域对象的集合，提供了查询和过滤这些对象的方法，使得领域对象的获取和管理更加方便。 + - 抽象接口：Repository定义了一个与持久化机制无关的接口，这使得领域层的代码可以在不同的持久化机制之间切换，而不需要修改业务逻辑。 + +- 用途： + - 数据访问抽象：Repository为领域层提供了一个清晰的数据访问接口，使得领域对象可以专注于业务逻辑的实现，而不是数据访问的细节。 + - 领域对象的查询和管理：Repository使得对领域对象的查询和管理变得更加方便和灵活，支持复杂的查询逻辑。 + - 领域逻辑与数据存储分离：通过Repository模式，领域逻辑与数据存储逻辑分离，提高了领域模型的纯粹性和可测试性。 + - 优化数据访问：Repository实现可以包含数据访问的优化策略，如缓存、批处理操作等，以提高应用程序的性能。 + +- 实现手段： + - 定义Repository接口：在领域层定义一个或多个Repository接口，这些接口声明了所需的数据访问方法。 + - 实现Repository接口：在基础设施层或数据访问层实现这些接口，具体实现可能是使用ORM（对象关系映射）框架，如MyBatis、Hibernate等，或者直接使用数据库访问API，如JDBC等。 + - 依赖注入：在应用程序中使用依赖注入（DI）来将具体的Repository实现注入到需要它们的领域服务或应用服务中。这样做可以进一步解耦领域层和数据访问层，同时也便于单元测试。 + - 使用规范模式（Specification Pattern）：有时候，为了构建复杂的查询，可以结合使用规范模式，这是一种允许将业务规则封装为单独的业务逻辑单元的模式，这些单元可以被Repository用来构建查询。 + +>Repository模式是DDD（领域驱动设计）中的一个核心概念，它有助于保持领域模型的聚焦和清晰，同时提供了灵活、可测试和可维护的数据访问策略。 + +仓储解耦的手段使用了依赖倒置的设计，所有领域需要的外部服务，不在直接引入外部的服务，而是通过定义接口的方式，让基础设施层实现领域层接口（仓储/适配器）的方式来处理。 + +那么也就是基础设置层负责原则对接`数据库`、`缓存`、`配置中心`、`RPC接口`、`HTTP接口`、`MQ推送`等各项资源，并承接领域服务的接口调用各项服务为领域层提供数据能力。 + +同时这也会体现出，领域层的实现是具有业务语义的，而到了基础设置层则没有业务语义，都是原子的方法。通过原子方法的组合为领域业务语义提供支撑。 + +### 2.5 领域编排 + +在 DDD 中，每一个领域都是界限上下文拆分的独立结果，而实现业务流程的功能则需要串联各个领域模块提供一整条链路的完整服务。所以也常说领域内事务一致性，领域外最终一致性。 + +同时这些领域模块因为是独立的，所以也可以被复用。在不同的场景功能诉求下，可以选择不同的领域模块进行组装，这个过程就像搭积木一样。 + +但这里有一个取舍，如果项目相对来说并不大，也没有太多的编排处理。那么可以直接让触发器层对接领域层，减少编排层后，编码会更加便捷。 + +### 2.6 触发器 + +在所有的模型都定义完成后，领域业务被串联了。那么接下来则是使用，而使用的方式可以包括；接口（http/rpc）、消息监听、定时任务等方式，这些方式统一被定义为触发动作。 + +由触发发起对编排功能的调用处理，如：定时任务做信贷的计息、开户成功消息通知返利优惠券、提供接口让外部调用授信逻辑等——这些都是触发动作。 diff --git a/docs/md/road-map/ddd-guide-02.md b/docs/md/road-map/ddd-guide-02.md new file mode 100755 index 000000000..c74c5e72a --- /dev/null +++ b/docs/md/road-map/ddd-guide-02.md @@ -0,0 +1,138 @@ +--- +title: DDD 建模方法 +lock: need +--- + +# DDD 建模 —— 架构师总说的风暴模型是什么？ + +作者：小傅哥 +

+ +
+ +上图是整个四色建模的指导图，通过寻找领域事件，发起事件命令，完成领域事件的过程，完成 DDD 工程建模。 + +- 蓝色 - 决策命令，是用户发起的行为动作，如：开始签到、开始抽奖、查看额度等。 +- 黄色 - 领域事件，过去时态描述。如：签到完成、抽奖完成、奖品发放完成。它所阐述的都是这个领域要完成的终态。 +- 粉色 - 外部系统，如你的系统需要调用外部的接口完成流程。 +- 红色 - 业务流程，用于串联决策命令到领域事件，所实现的业务流程。一些简单的场景则直接由决策命令到领域事件就可以了。 +- 绿色 - 只读模型，做一些读取数据的动作，没有写库的操作。 +- 棕色 - 领域对象，每个决策命令的发起，都是含有一个对应的领域对象。 + +**👩🏻‍🏫敲黑板** 综上，上图左下部分的示意图表达的是：“一个用户，通过一个策略命令，使用领域对象，通过业务流程，完成2个领域事件，调用1次外部接口”的过程。我们在整个 DDD 建模过程中，就是在寻找这些节点。 + +## 3. 超市举例 + +我们先通过一个真实场景的案例，代入下 DDD 四色建模的术语，这样可以更有益大家对四色建模理解。这个场景是一个在超市购物的场景。想象下，一个男人，得到了老婆的"命令"，去大超市拿着空的购物车，推进去一圈圈的走，最终完成购物打车回家。 + +
+ +
+ +- 脑子中的想法，是媳妇给下达的指令。我们可以理解为决策命令。行为人带着决策命令来到超市。 +- 购物车是一种实体，需要填充数据的实体。行为人，带着实体，进入到超市中从各个货架选购商品，装入购物车。选购商品为业务流程，装满的购物车为领域事件。也就是最终态，完成媳妇交代的任务。而手里的烟，则是另外一个领域事件。也就是说，一次的行为动作可以完成多个领域事件。 +- 最终购物完成后，打车回家。则是下一个领域流程。通过把从加入出门、做地铁、进超市、采购、打车回家，一整条领域串联起来就是领域编排。 + +综上，DDD 的领域建模过程，就是一种真实的场景头脑风暴过程，所以可以让更多人同时讨论，拆分出各项领域的边界和领域模型。 + +## 4. 业务案例 + +接下来，我们在以一个真实的业务场景来分析系统的四色建模过程： + +### 1. 产品诉求 + +如图，是一个复杂的营销抽奖场景玩法需求，涵盖了；`活动配置`、`签到&奖励`、`活动账户`、`抽奖策略「责任链+规则树」`、`库存扣减`、`抽奖满N次后阶梯抽奖`等。面对这样的复杂系统，非常适合使用 DDD 落地。 + +
+ +
+ +分析需求； + +1. 整体概率相加，总和为1或者分值计算，概率范围千分位 +2. 抽奖为免费抽奖次数 + 用户消耗个人积分抽奖 +3. 抽奖活动可给用户分配可抽奖次数，通过点击签到发放 +4. 活动延伸配置用户库存消耗管理，单独提供表配置各类库存 + 用户可用总库存、用户可用日库存 +5. 部分抽奖规则，需要抽奖n次后解锁，才能有机会抽取 +6. 抽奖完成增加（运气值/积分值/抽奖次数）记录，让用户获得奖品。 +7. 奖品对接，自身的积分、内部系统的奖品 +8. 随机积分，发给你积分。 +9. 黑名单用户抽奖，则给予固定的奖品。 + +### 2. 用例图 + +根据业务需求画系统用例图； + +
+ +
+ +- 用例图（英语：use case diagram）是用户与系统交互的最简表示形式，展现了用户和与他相关的用例之间的关系。通过用例图，人们可以获知系统不同种类的用户和用例。用例图也经常和其他图表配合使用。 +- 用例图，也可以等同于是用户故事（英语：User story）（软件开发和项目管理中的常用术语），主旨是以日常语言或商务用语撰写句子，是一段简单的功能表述。以客户或使用者的观点撰写下有价值的功能、引导、框架来与使用者进行互动，进而推动工作进程。可以被认为是一种规格文件，但更精确而言，它代表客户的需求与方向。以该用户故事来反应对象在组织内的其工作职责、范围、需要进行的任务等。用户故事在敏捷开发方法中用来定义系统需要提供的功能和实现需求管理。 +- 尽管用例本身会涉及大量细节和各种可能性，用例图却能提纲挈领地让人了解系统概况。它为“系统做什么”提供了简化了的图形表示，因此被誉为“搭建系统的蓝图”。 + +### 3. 寻找领域事件 + +接下来，大量的时间，都是在挖掘领域事件。这个过程就是一堆人头脑风暴的过程，避免错失流程节点。 + +
+ +
+ +- 根据产品 PRD 文档，一起开会梳理有哪些领域事件。其实大多数领域事件一个人都可以想到，只是有些部分小的场景和将来可能产生的事件不一定覆盖全。所以要通过产品、测试、以及团队的架构师，一起讨论。 +- 像是整个大营销的抽奖会包括如图所列举的事件。在列举这个阶段，你用在乎格式。也可以是每个人准备好黄色便签纸，想到一个就贴到黑板上一个，只是穷举完成。—— 实际做DDD中，也是这样用便签纸贴黑板，所以用不同的颜色做区分。 + +### 4. 识别领域角色和对象 + +在确定了领域事件以后，接下来要做的就是通过决策命令串联领域事件，并填充上所需要的领域对象。这块的操作，新手可以分开处理，如先给领域事件添加决策命令、执行用户和领域对象，最后再串联流程。就像 `事件风暴定义` 中的示意一样。 + +
+ +
+ +- 首先，通过用户的行为动作，也就是决策命令，串联到对应的领域事件上。并对复杂的流程提供出红色的业务流程。 +- 之后，为决策命令添加领域对象，每一个领域在整个流程中都起到了至关重要的作用。 + +### 5. 划分领域边界 + +有了识别出来的领域角色的流程，就可以非常容易的划分出领域边界了。先在事件风暴图上圈出领域边界，之后在单独提供领域划分。 + +#### 5.1 圈出领域 + +
+ +
+ +#### 5.2 领域边界 + +
+ +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主小傅哥。 + +凡是做到架构师岗位的，都是具有一定技术思维敏感性的，不会主观评价好和坏，但能推演出业务与技术的迭代发展被动熵增与减熵增的意识。就像拿MVC与DDD对比，也能确切的感受到，在架构方面对比于单体应用的分布式架构，是要额外引入非常多的技术栈使用。但这些模块在 MVC 下并没有设计好如何"安置"他们，就像一个老城区里突然引入了很多外来人口，不知道怎么安置一样。**不过 DDD 就像雄安新区做了整体规划！** + +
+ +
+ +**什么是系统的工程结构，工程框架的作用是什么？** + +其实，工程结构的存在作用目的，是为了承载工程系统开发的模型划分，定义工程服务开发过程中实施标准。说白了，就是你在工程实现时，在哪个层访问数据库、哪个层使用缓存、哪个层调用外部接口、哪个层做功能实现，这就是工程框架结构定义的目的。 + +但在 `Service + 贫血模型` 的三层结构开发指导下，是没有细分出面向对象工程结构设计的趋于划分的。所以在通常意义的 MVC 下，开发过程所有需要的内容，都会堆砌到 Service 实现类中。这也是为什么 DDD 领域驱动设计的落地工程结构，会出现；洋葱架构、整洁架构、菱形架构、六边形架构等这些架构模型。因为我们需要更细致的划分，来承载 DDD 设计概念中映射的领域、仓储、适配、编排、触发，并重视面向对象过程。—— 其实你一上学，学Java就开始学面向对象了，只不过一点点在忘记它。 + +>本节是DDD概率系列的第3节，讲解 DDD 架构设计，在 [bugstack.cn](https://bugstack.cn) 路书中有完整系列内容，可以查阅。 + +## 一、为啥需要架构 + +说到开发代码为啥需要架构，就想买了个房子，为啥要隔出厨房、客厅、卧室、卫生间一样，核心目的就是让不同的职责分配到不同的区域内。虽然在代码中是没有马桶要放卫生间、沙发要放客厅、床要放卧室。但他有一些列的科目信息要引入到工程。 + +**在工程开发时会涉及到的核心科目；** + +
+ +
+ +如；统一的异常、数据库的连接、日志的打印、外部服务的调用、消息的监听、任务的轮训以及服务的实现等一些列的东西要处理，分配到不同的工程包下承载。在 DDD 之前，我们一直用 MVC 的分层结构承接这些内容； + +
+ +
+ +通用的、配置的、组件的、持久化的、内部的、外部的，在以往的单体应用时代开发下，其实是没有这么多东西的，那时候的工程结构都偏向于 Service + 贫血模型实现。 + +但随着微服务的演进，越来越多的内容被填充到工程中，这个时候你细心的查看架构，就会发现原本的 MVC 结构其实已经变的非常混乱了。一个 Service 中为了实现自己的功能，要引入一堆的东西，这些原子的功能与 Service 自身的服务耦合在一块。也导致了工程的维护成本越来越大。 + +>这样的三层工程结构分配方式，对于要承载庞大的分布式技术栈体系显然是有点小马拉大车，三缸机带不动SUV一样。 + +## 二、工程结构设计 + +2004年，Eric Evans 在发表了一部名为《Domain Driven Design》的著作。2005年 Alistair Cockburn 提出的“六边形关系图”理论，2008年 Jeffrey Palermo 提出了洋葱架构。虽然这些架构并不是专门为 DDD 而出，但巧的是这些架构都在 DDD 一书发表之后陆续推出新的架构模型。同时这些架构的分层设计方式也都与 DDD 非常契合，在这些架构下也可以很好的落地 DDD 设计方法。 + +
+ +
+无论是六边形架构，还是洋葱架构，或是 张毅老师 - http://zhangyi.xyz/ 提到的南向网关/北向网关的菱形架构，他们的目标都是以领域服务为核心，隔离内部实现与外部资源的耦合。 + +在 DDD 分层架构下，以支撑 domain 核心领域实现拆分出基础设施（infrastructure），来承接对外部资源的调用。触发器（trigger）向外部提供服务。之后 app 为应用启动、api 为接口定义、types 为通用信息、case 为编排。 + +在这样一套结构下，用于开发工程的各项科目也可以被优雅的分配到各个分层结构了。相对于 Service + 数据模型的贫血模型结构，现在就主要以 domain 为核心开发业务功能，不会在 domain 工程模块下，引入其他各类外部组件了，这样就可以更加关心业务功能开发。 + +之后是这样的思想映射到工程中，常见的分层结构会有两套，一套是整洁分层，另外一套是六边形分层。 + +### 1. 整洁架构 - 工程结构 + +
+ +
+ +- 整洁架构的分包形式，会将所有的外部依赖使用和工程内要对外的，统一定义到适配器层。这里可以理解为对外适配和对内适配。 +- 阿里的 cola 偏整洁架构 [阿里架构 cola 的相关内容](https://www.aliyun.com/sswb/610119.html) + +### 2. 六边形架构 - 工程结构 + +
+ +
+ +六边形架构，会把本身提供到外部的放到trigger，让接口调用、消息监听、任务调度，都可以统一一个入口处理。而对于需要调用外部同类的能力统一放到 infrastructure 基础设施层，包括；数据库、缓存、配置、调用其他方的接口。 + +## 三、领域模型设计 + +虽然大家用的都是 DDD，也都有对应的模块和分包，但在细节之处还是会有一些差异。就像家里的家庭成员，衣服、裤子、鞋子，是所有人的衣服都放一起，还是每个人有独立的衣柜只放自己的。这块是有差异的。另外这东西没有绝对的好和坏，就像厨房里的碗筷是是放一起的，卫生间的马桶也是共用的，这说明分包也是需要按照最符合自己所需来设定。 + +### 1. 分包方式 + +如下，是两种分包方式； + +
+ +
+ +- 方式1；DDD 领域科目类型分包，类型之下写每个业务逻辑。 +- 方式2；业务领域分包，每个业务领域之下有自己所需的 DDD 领域科目。 + +比如，你现在一个工程下有用户、积分、抽奖、支付，（紧凑的聚合类微服务有时候更易于维护），那么这些包一种是分为独立的业务包方式2这种，另外一种就是大家都在一个坛子里吃饭，要啥去各个地方找。所以你更倾向于那种呢？ + +### 2. 领域模型 + +DDD 领域驱动设计的中心，主要在于领域模型的设计，以领域所需驱动功能实现和数据建模。一个领域服务下面会有多个领域模型，每个领域模型都是一个充血结构。**一个领域模型 = 一个充血结构** + +
+ +
+ +- model 模型对象； + - aggreate：聚合对象，实体对象、值对象的协同组织，就是聚合对象。 + - entity：实体对象，大多数情况下，实体对象(Entity)与数据库持久化对象(PO)是1v1的关系，但也有为了封装一些属性信息，会出现1vn的关系。 + - valobj：值对象，通过对象属性值来识别的对象 By 《实现领域驱动设计》 +- repository 仓储服务；从数据库等数据源中获取数据，传递的对象可以是聚合对象、实体对象，返回的结果可以是；实体对象、值对象。因为仓储服务是由基础层(infrastructure) 引用领域层(domain)，是一种依赖倒置的结构，但它可以天然的隔离PO数据库持久化对象被引用。 +- service 服务设计；这里要注意，不要以为定义了聚合对象，就把超越1个对象以外的逻辑，都封装到聚合中，这会让你的代码后期越来越难维护。聚合更应该注重的是和本对象相关的单一简单封装场景，而把一些重核心业务方到 service 里实现。**此外；如果你的设计模式应用不佳，那么无论是领域驱动设计、测试驱动设计还是换了三层和四层架构，你的工程质量依然会非常差。** +- 对象解释 + - DTO 数据传输对象 (data transfer object)，DAO与业务对象或数据访问对象的区别是：DTO的数据的变异子与访问子（mutator和accessor）、语法分析（parser）、序列化（serializer）时不会有任何存储、获取、序列化和反序列化的异常。即DTO是简单对象，不含任何业务逻辑，但可包含序列化和反序列化以用于传输数据。 + +## 四、分层调用链路 + +接下来我们把 DDD 的分层架构平铺展开，看看从一个接口的实现到各个模块分层中的调用链路关系是什么样的。这样在做自己的代码开发中也可以参考到应该把什么的功能分配到哪个模块中处理。 + +![](https://bugstack.cn/images/roadmap/tutorial/road-map-ddd-05.png) + +从APP层、触发器层、应用层，这三块主要对领域层的上下文逻辑封装、触发式(MQ、HTTP、JOB)使用，并最终在应用层中打包发布上线。这一部分的都是使用的处理，所以也不会有太复杂的操作。 + +当进入领域层开始，也是智力集中体现的开始了。所有你对工程的抽象能力，都在这一块区域体现。 + +**关于对象定义**；vo、po、dto、entity、aggregate、req、res、response

三个领域模块。并在每个模块下提供了对应的测试内容。这块是整个模型的重点，其他模块都可以通过测试看到这里的调用过程。 + +### 3. 领域 + +一个领域模型中包含3个部分；model、repository、service 三部分； +- model 对象的定义 【含有；valobj = VO、entity、Aggregate】 +- repository 仓储的定义【含有PO】 +- service 服务实现 + +以上3个模块，一般也是大家在使用 DDD 时候最不容易理解的分层。比如 model 里还分为；valobj - 值对象、entity 实体对象、aggregates 聚合对象； +- **值对象**：表示没有唯一标识的业务实体，例如商品的名称、描述、价格等。 +- **实体对象**：表示具有唯一标识的业务实体，例如订单、商品、用户等； +- **聚合对象**：是一组相关的实体对象的根，用于保证实体对象之间的一致性和完整性； + +关于model中各个对象的拆分，尤其是聚合的定义，会牵引着整个模型的设计。当然你可以在初期使用 DDD 的时候不用过分在意领域模型的设计，可以把整个 domain 下的一个个包当做充血模型结构，这样编写出来的代码也是非常适合维护的。 + +### 4. 环境(开发/测试/上线) + +**源码**：`xfg-frame-ddd/pom.xml` + +```pom + + dev + + true + + + dev + + + + test + + test + + + + prod + + prod + + +``` + +- 定义环境；开发、测试、上线。 + +**源码**：`xfg-frame-app/application.yml` + +```java +spring: + config: + name: xfg-frame + profiles: + active: dev # dev、test、prod +``` + +- 除了 pom 的配置，还需要在 application.yml 中指定环境。这样就可以对应的加载到；`application-dev.yml`、`application-prod.yml`、`application-test.yml` 这样就可以很方便的加载对应的配置信息了。尤其是各个场景中切换会更加方便。 + +### 5. 切面 + +一个工程开发中，有时候可能会有很多的统一切面和启动配置的处理，这些内容都可以在 xfg-frame-app 完成。 + +
+ +
+ +**源码**：`cn.bugstack.xfg.frame.aop.RateLimiterAop` + +```java +@Slf4j +@Aspect +public class RateLimiterAop { + + private final long timeout; + private final double permitsPerSecond; + private final RateLimiter limiter; + + public RateLimiterAop(double permitsPerSecond, long timeout) { + this.permitsPerSecond = permitsPerSecond; + this.timeout = timeout; + this.limiter = RateLimiter.create(permitsPerSecond); + } + + @Pointcut("execution(* cn.bugstack.xfg.frame.trigger..*.*(..))") + public void pointCut() { + } + + @Around(value = "pointCut()", argNames = "jp") + public Object around(ProceedingJoinPoint jp) throws Throwable { + boolean tryAcquire = limiter.tryAcquire(timeout, TimeUnit.MILLISECONDS); + if (!tryAcquire) { + Method method = getMethod(jp); + log.warn("方法 {}.{} 请求已被限流，超过限流配置[{}/秒]", method.getDeclaringClass().getCanonicalName(), method.getName(), permitsPerSecond); + return Response.builder() + .code(Constants.ResponseCode.RATE_LIMITER.getCode()) + .info(Constants.ResponseCode.RATE_LIMITER.getInfo()) + .build(); + } + return jp.proceed(); + } + + private Method getMethod(JoinPoint jp) throws NoSuchMethodException { + Signature sig = jp.getSignature(); + MethodSignature methodSignature = (MethodSignature) sig; + return jp.getTarget().getClass().getMethod(methodSignature.getName(), methodSignature.getParameterTypes()); + } + +} +``` + +**使用** + +```java +# 限流配置 +rate-limiter: + permits-per-second: 1 + timeout: 5 +``` + +- 这样你所有的通用配置，又和业务没有太大的关系的，就可以直接写到这里了。—— 具体可以参考代码。 + +## 六、工程测试验证 + +- 首先；整个工程由 SpringBoot 驱动，提供了 road-map.sql 测试 SQL 库表语句。你可以在自己的本地mysql上进行执行。它会创建库表。 +- 之后；在 application.yml 配置数据库链接信息。 +- 之后就可以打开 ApiTest 进行测试了。你可以点击 Application 类的绿色箭头启动工程，使用触发器里的接口调用测试，或者单元测试RPC接口，小傅哥也提供了泛化调用的方式。 + +
+ +
+ +- 如果你正常获取了这样的结果信息，那么说明你已经启动成功。接下来就可以对照着DDD的结构进行学习，以及使用这样的工程结构开发自己的项目。 diff --git a/docs/md/road-map/ddd-model.md b/docs/md/road-map/ddd-model.md new file mode 100644 index 000000000..d4d443a2b --- /dev/null +++ b/docs/md/road-map/ddd-model.md @@ -0,0 +1,15 @@ +--- +title: DDD 建模案例 +lock: need +--- + +# 架构的本质之 DDD 四色建模 + +作者：小傅哥 +

+ +
+ +- 如果你接触过较大型且已经长期维护项目的 MVC 架构，你就会发现这里的 DAO、PO（持久化）、VO（业务对象） 对象，在 Service 层相互调用。那么长期开发后，就导致了各个 VO 里的属性字段数量都被撑的特别大。这样的开发方式，将`”状态”`、`“行为“`分离到不同的对象中，代码的意图渐渐模糊，膨胀、臃肿和不稳定的架构，让迭代成本增加。 +- 而 DDD 架构首先以解决此类问题为主，将各个属于自己领域范围内的行为和逻辑封装到自己的领域包下处理。这也是 DDD 架构设计的精髓之一。它希望在分治层面合理切割问题空间为更小规模的若干子问题，而问题越小就容易被理解和处理，做到高内聚低耦合。这也是康威定律所提到的，解决复杂场景的设计主要分为：分治、抽象和知识。 + +## 二、简化理解 + +在给大家讲解 MVC 架构的时候，小傅哥提到了一个简单的开发模型。开发代码可以理解为：`“定义属性 -> 创建方法 -> 调用展示” `但这个模型结构过于简单，不太适合运用了各类分布式技术栈以及更多逻辑的 DDD 架构。所以在 DDD 这里，我们把开发代码可以抽象为：`“触发 -> 函数 -> 连接”` 如图； + +
+ +
+ +- DDD 架构常用于微服务场景，因此也一个系统的调用方式就不只是 HTTP 还包括；`RPC 远程`、`MQ 消息`、`TASK 任务`，因此这些种方式都可以理解为触发。 +- 通过触发调用函数方法，我们这里可以把各个服务都当成一个函数方法来看。而函数方法通过连接，调用到其他的接口、数据库、缓存来完成函数逻辑。 + +接下来，小傅哥在带着大家把这些所需的模块，拆分到对应的DDD系统架构中。 + +## 三、架构分层 + +如下是 DDD 架构的一种分层结构，也可以有其他种方式，核心的重点在于适合你所在场景的业务开发。以下的分层结构，是小傅哥在使用 DDD 架构多种的方式开发代码后，做了简化和处理的。右侧的连线是各个模块的依赖关系。接下来小傅哥就给大家做一下模块的介绍。 + +
+ +
+ +- **接口定义 - xfg-frame-api**：因为微服务中引用的 RPC 需要对外提供接口的描述信息，也就是调用方在使用的时候，需要引入 Jar 包，让调用方好能依赖接口的定义做代理。 +- **应用封装 - xfg-frame-app**：这是应用启动和配置的一层，如一些 aop 切面或者 config 配置，以及打包镜像都是在这一层处理。你可以把它理解为专门为了启动服务而存在的。 +- **领域封装 - xfg-frame-domain**：领域模型服务，是一个非常重要的模块。无论怎么做DDD的分层架构，domain 都是肯定存在的。在一层中会有一个个细分的领域服务，在每个服务包中会有【模型、仓库、服务】这样3部分。 +- **仓储服务 - xfg-frame-infrastructure**：基础层依赖于 domain 领域层，因为在 domain 层定义了仓储接口需要在基础层实现。这是依赖倒置的一种设计方式。 +- **领域封装 - xfg-frame-trigger**：触发器层，一般也被叫做 adapter 适配器层。用于提供接口实现、消息接收、任务执行等。所以对于这样的操作，小傅哥把它叫做触发器层。 +- **类型定义 - xfg-frame-types**：通用类型定义层，在我们的系统开发中，会有很多类型的定义，包括；基本的 Response、Constants 和枚举。它会被其他的层进行引用使用。 +- **领域编排【可选】 - xfg-frame-case**：领域编排层，一般对于较大且复杂的的项目，为了更好的防腐和提供通用的服务，一般会添加 case/application 层，用于对 domain 领域的逻辑进行封装组合处理。 + +## 四、领域分层 + +DDD 领域驱动设计的中心，主要在于领域模型的设计，以领域所需驱动功能实现和数据建模。一个领域服务下面会有多个领域模型，每个领域模型都是一个充血结构。**一个领域模型 = 一个充血结构** + +
+ +
+ +- model 模型对象； + + - aggreate：聚合对象，实体对象、值对象的协同组织，就是聚合对象。 + - entity：实体对象，大多数情况下，实体对象(Entity)与数据库持久化对象(PO)是1v1的关系，但也有为了封装一些属性信息，会出现1vn的关系。 + - valobj：值对象，通过对象属性值来识别的对象 By 《实现领域驱动设计》 +- repository 仓储服务；从数据库等数据源中获取数据，传递的对象可以是聚合对象、实体对象，返回的结果可以是；实体对象、值对象。因为仓储服务是由基础层(infrastructure) 引用领域层(domain)，是一种依赖倒置的结构，但它可以天然的隔离PO数据库持久化对象被引用。 +- service 服务设计；这里要注意，不要以为定义了聚合对象，就把超越1个对象以外的逻辑，都封装到聚合中，这会让你的代码后期越来越难维护。聚合更应该注重的是和本对象相关的单一简单封装场景，而把一些重核心业务方到 service 里实现。**此外；如果你的设计模式应用不佳，那么无论是领域驱动设计、测试驱动设计还是换了三层和四层架构，你的工程质量依然会非常差。** + +- 对象解释 + - DTO 数据传输对象 (data transfer object)，DAO与业务对象或数据访问对象的区别是：DTO的数据的变异子与访问子（mutator和accessor）、语法分析（parser）、序列化（serializer）时不会有任何存储、获取、序列化和反序列化的异常。即DTO是简单对象，不含任何业务逻辑，但可包含序列化和反序列化以用于传输数据。 + +## 五、架构源码 + +### 1. 环境 + +-

三个领域模块。并在每个模块下提供了对应的测试内容。这块是整个模型的重点，其他模块都可以通过测试看到这里的调用过程。 + +### 3. 领域 + +一个领域模型中包含3个部分；model、repository、service 三部分； +- model 对象的定义 【含有；valobj = VO、entity、Aggregate】 +- repository 仓储的定义【含有PO】 +- service 服务实现 + +以上3个模块，一般也是大家在使用 DDD 时候最不容易理解的分层。比如 model 里还分为；valobj - 值对象、entity 实体对象、aggregates 聚合对象； +- **值对象**：表示没有唯一标识的业务实体，例如商品的名称、描述、价格等。 +- **实体对象**：表示具有唯一标识的业务实体，例如订单、商品、用户等； +- **聚合对象**：是一组相关的实体对象的根，用于保证实体对象之间的一致性和完整性； + +关于model中各个对象的拆分，尤其是聚合的定义，会牵引着整个模型的设计。当然你可以在初期使用 DDD 的时候不用过分在意领域模型的设计，可以把整个 domain 下的一个个包当做充血模型结构，这样编写出来的代码也是非常适合维护的。 + +### 4. 环境(开发/测试/上线) +

+spring: + config: + name: xfg-frame + profiles: + active: dev # dev、test、prod +``` + +- 除了 pom 的配置，还需要在 application.yml 中指定环境。这样就可以对应的加载到；`application-dev.yml`、`application-prod.yml`、`application-test.yml` 这样就可以很方便的加载对应的配置信息了。尤其是各个场景中切换会更加方便。 + +### 5. 切面 + +一个工程开发中，有时候可能会有很多的统一切面和启动配置的处理，这些内容都可以在 xfg-frame-app 完成。 + +
+ +
+ +**源码**：`cn.bugstack.xfg.frame.aop.RateLimiterAop` + +```java +@Slf4j +@Aspect +public class RateLimiterAop { + + private final long timeout; + private final double permitsPerSecond; + private final RateLimiter limiter; + + public RateLimiterAop(double permitsPerSecond, long timeout) { + this.permitsPerSecond = permitsPerSecond; + this.timeout = timeout; + this.limiter = RateLimiter.create(permitsPerSecond); + } + + @Pointcut("execution(* cn.bugstack.xfg.frame.trigger..*.*(..))") + public void pointCut() { + } + + @Around(value = "pointCut()", argNames = "jp") + public Object around(ProceedingJoinPoint jp) throws Throwable { + boolean tryAcquire = limiter.tryAcquire(timeout, TimeUnit.MILLISECONDS); + if (!tryAcquire) { + Method method = getMethod(jp); + log.warn("方法 {}.{} 请求已被限流，超过限流配置[{}/秒]", method.getDeclaringClass().getCanonicalName(), method.getName(), permitsPerSecond); + return Response.builder() + .code(Constants.ResponseCode.RATE_LIMITER.getCode()) + .info(Constants.ResponseCode.RATE_LIMITER.getInfo()) + .build(); + } + return jp.proceed(); + } + + private Method getMethod(JoinPoint jp) throws NoSuchMethodException { + Signature sig = jp.getSignature(); + MethodSignature methodSignature = (MethodSignature) sig; + return jp.getTarget().getClass().getMethod(methodSignature.getName(), methodSignature.getParameterTypes()); + } + +} +``` + +**使用** + +```java +# 限流配置 +rate-limiter: + permits-per-second: 1 + timeout: 5 +``` + +- 这样你所有的通用配置，又和业务没有太大的关系的，就可以直接写到这里了。—— 具体可以参考代码。 + +## 六、测试验证 + +- 首先；整个工程由 SpringBoot 驱动，提供了 road-map.sql 测试 SQL 库表语句。你可以在自己的本地mysql上进行执行。它会创建库表。 +- 之后；在 application.yml 配置数据库链接信息。 +- 之后就可以打开 ApiTest 进行测试了。你可以点击 Application 类的绿色箭头启动工程，使用触发器里的接口调用测试，或者单元测试RPC接口，小傅哥也提供了泛化调用的方式。 + +
+ +
+ +- 如果你正常获取了这样的结果信息，那么说明你已经启动成功。接下来就可以对照着DDD的结构进行学习，以及使用这样的工程结构开发自己的项目。 diff --git a/docs/md/road-map/disruptor.md b/docs/md/road-map/disruptor.md new file mode 100644 index 000000000..73362e753 --- /dev/null +++ b/docs/md/road-map/disruptor.md @@ -0,0 +1,183 @@ +--- +title: Disruptor +lock: need +--- + +# Disruptor 高性能环形消息队列应用，Log4j 2 也用到了这套技术。 + +作者：小傅哥 +

+ +
+ +**什么是柔性事务？** + +在分布式软件系统架构设计中，所有的并发资源的竞争，都会往`无锁化`、`非独占竞争`，以及`柔性事务`设计。柔性事务用于替代传统事务管理中（如ACID属性：原子性、一致性、隔离性、持久性），在分布式架构系统中的使用场景。通过消息、补偿，协调不同服务间的一致性。 + +
+ +
+ +那么在消息的使用中，除了有 MQ 消息，使用于微服务之间。还有本地消息，可以作用在各个领域间驱动流程。关于本地消息可以用，Spring 的监听、Redis 发布订阅、Guava EventBus 事件总线，这些内容在小傅哥博客 [bugstack.cn](https://bugstack.cn) 《路书》中有相关的案例。之后本节咱们介绍一个新的高性能组件 Disruptor 的使用。 + +## 一、关于 Disruptor + +Disruptor 是一种高性能的并发框架，最初由 LMAX 开发，用于解决高吞吐量、低延迟的消息处理问题。它提供了一种无锁的、有序的事件处理模型，非常适合处理需要高性能的场景。Disruptor 本身并不是用于实现事务的框架，而是一个事件处理器。因此，要在 Disruptor 上实现柔性事务，需要结合其事件处理能力与柔性事务的模式。 + +- 源码：[https://github.com/LMAX-Exchange/disruptor](https://github.com/LMAX-Exchange/disruptor) +- 文档：[https://lmax-exchange.github.io/disruptor/](https://lmax-exchange.github.io/disruptor/) - 谷歌浏览器右键点翻译为中文。 + +## 二、实战案例 + +### 1. 工程结构 + +小傅哥准备好了一份基于 Disruptor 事件消息的使用案例工程，你可以直接上手体现。 + +

+ +
+ +**啥是云服务器？** + +云服务器，就等同于自己的另外一个电脑💻，在另外一台电脑部署 redis、mysql、mq等，本地电脑连接过去使用。尤其是 Windows 电脑用户，真心建议搞个云服务器，否则你会浪费非常多的时间这套 Windows 适配问题。 + +
+ +
+ +这样有了云服务器，就可以不用嚯嚯本地电脑了，安装了卸，卸了安装，把自己本机电脑环境弄的乱码起糟，全是费时费力的事。有这精力，不如用一台云服务器部署环境，开发完成项目后，再上线云服务器。既节省本地电脑资源，又锻炼了云服务器操作，起步一举两得！ + +
+ +
+ +不过，放心！别担心你不会用云服务器，因为小傅哥已经给你准备了一件安装云服务器环境的脚本，和各类部署环境和构建项目的视频。**即使是小卡拉米，也能跟着学习下来。** + +> 🧧小傅哥还提供了非常多的编程实战项目，包括；业务的、组件的、AI的、源码的、轮子的，可以关注公众号「bugstack虫洞栈」回复「星球」加入。 + +## 一、优惠云服务器地址 + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +**好用，真的好用！** 自从使用 Docker 后，我可以非常简单的`安装`、`使用`、`卸载`各类所需的软件，如；MySql、Redis、RabbitMQ、XXL-Job、FRP，等一些列开发环境和我自己开发的好的项目进行上线发布。以前一个MySql安装到卸载，可能半天时间都没了。但有 Docker 后，我自己既可以是开发工程师也是可以是软件实施工程师。因为他可以一行脚本即可完成所有的操作，脚本在，环境就在，服务就在。 + +
+ +
+ +**那 Docker 是什么呢？** + +Docker 是什么，其实来自于 Docker 的图标已经说明。Docker 的图标是一条鲸鱼 🐳一样的大船，上面摆放了很多集装箱。你可以把这些集装箱当做是一个个不同的应用程序，虽然不同但可以统一用一套集装箱（脚本命令）承载，并承放在统一一条大船上（环境上）。而且这些集装箱都有自己的编号ID（有自己的IP）互相隔离，不受影响。 + +Docker 是一个用于开发、发布和运行应用程序的开放平台。Docker 可让您将应用程序与基础架构分离，以便快速交付软件。借助 Docker，您可以像管理应用程序一样管理基础架构。通过利用 Docker 的发布、测试和部署代码方法，您可以显著减少编写代码和在生产中运行代码之间的延迟。 + +官网：[https://www.docker.com/](https://www.docker.com/) +文档：[https://docs.docker.com/get-started/docker-overview/](https://docs.docker.com/get-started/docker-overview/) + +## 一、Docker 安装在哪 + +Docker 可以安装在 Windows + wsl2、Mac、Linux，支持 ARM、AMD 架构。它可以通过软件下载安装和执行脚本命令安装，也可以通过云服务器提供的镜像直接购买云服务器时选择使用。我们可以看下 Docker 和虚拟机安装在操作系统上的关系来了解 Docker 的安装位置。 + +
+ +
+ +与虚拟机的安装使用相比，Docker 会把应用所需的依赖、函数库、甚至其他的软件应用可以一起打包成一个镜像，这样在应用程序运行时，就可以直接调用本地函数库，然后和 Linux 内核进行通信。有了这样的设计，你也就不需要关心每一个应用所需的环境都是啥了，也不用为每一个应用安装各类环境到 Linux 或者虚拟机了。也就做到了跨系统的运行。这有点类似于 Java 的 JVM 虚拟机。 + +- 本地安装：[https://www.docker.com/](https://www.docker.com/) - 下载 Mac、Windows 你需要的版本进行安装。 +- 云服务器：[https://bugstack.cn/md/road-map/docker.html](https://bugstack.cn/md/road-map/docker.html) - centos 7.9 其他的也都类似操作即可。 + +>安装完成后都可以通过命令操作，安装、部署、卸载软件。文末提供了教程链接。 + +## 二、Docker 怎么工作 + +Docker 为了屏蔽软件使用差异，会统一对这些软件进行镜像打包，把一个软件所需的各类环境都打包到镜像中。我们在使用的时候，就是使用各类平台提供好的软件镜像，进行服务部署。同样的我们也可以作为镜像提供方，把我们的应用程序 SpringBoot、React、VUE 等，打包成镜像，让我们在其他地方，如云服务器进行部署。或者提供给全网的人员，进行部署使用。 + +
+ +
+ +如图，这是一整套的，本地拉取镜像、部署环境、开发代码、发布镜像，再到云服务器拉取镜像、部署项目和环境的过程。在这个过程中，我们也可以借助于如 Github Action 完成镜像的构建和发布，还可以在云服务器上直接构建镜像，减少了拉取拉取的过程。 + +> 你可以理解为，Docker 就是一个中心和一个客户端，中心管理镜像，客户端拉取使用或者构建发布镜像。 + +## 三、Docker 命令说明 + +Docker 的操作是通过脚本命令配置和执行完成使用，不过不用害怕命令😱，命令是最简单、直接、可靠的方式。当你习惯命令以后，你会很喜欢它，并且知道只要执行这个命令就一定会有结果，而不像被软件包装后，不确定是软件的问题还是命令的问题。 + +Docker 安装软件分为直接使用和通过 Docker Compose 脚本。直接使用如；`docker run -d --restart=always --name portainer -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock portainer/portainer` 这条命令会自动拉取和执行脚本。不过对于更大的项目部署，Docker Compose 脚本更好用。 + +
+ +
+ +- 如图，是整个 Docker Compose 在配置一套执行脚本后，各个脚本的核心用途。当然 Docker Compose 还有不少的命令，比如容量的限制、端口的处理、默认的命令等，都是可以操作的，凡是你想的合理的，它都可以支持。 +- 特别注意，安装到云服务器的docker部署的应用，外部访问需要走公网IP:Port端口，之后这个端口要在安全组打开。这样就类似于你再本地自己的电脑发，访问另外一台电脑上的服务了。 +- 如果在使用中遇到其他命令不理解的，可以让 [openai](https://openai.itedus.cn) 解释。 + +## 四、Docker 实操教程 + +此外，为了大家更好的使用 Docker 搭建各类环境，小傅哥为大家准备好了文档和视频。可以放心食用。 + +- 文档：[https://bugstack.cn/md/road-map/docker.html](https://bugstack.cn/md/road-map/docker.html) - 这是一个系列，你可以从左侧目录选择阅读。 +- 视频：[https://www.bilibili.com/video/BV1xw411W7xf](https://www.bilibili.com/video/BV1xw411W7xf) - 对应一整套的视频，手把手操作。 \ No newline at end of file diff --git a/docs/md/road-map/docker.md b/docs/md/road-map/docker.md new file mode 100644 index 000000000..3fb609b15 --- /dev/null +++ b/docs/md/road-map/docker.md @@ -0,0 +1,386 @@ +--- +title: Docker 环境配置（手动安装） +lock: need +--- + +# Docker 环境配置（手动安装） + +作者：小傅哥 +

+ +
+ +**Ai Agent 会结合到各个场景！** + +可以想象，将来我们使用的各种工具，都会很方便的以标准的协议方式结合到 AI Agent 智能体。这就像小傅哥，25年，年初开始做 Ai Agent 时，对一个智能体的执行过程，是需要自己进行分析，设计，实现的（`那时候我就在讲，Agent 也会出标准框架`）。到了年中的时候 Google ADK 除了 0.1.0 最初的版本，年尾发布了 0.4.0，这个框架提供了构建智能体的最基本框架，可以整合 Spring AI、Langchain4j 快速构建智能体。 + +>Spring AI、Langchain4j 提供的是 AI 封装能力，Google ADK 提供的是 Agent 执行能力（并行、循环、串行）的组装和使用。 + +未来（甚至不会太久），各个软件与 Ai Agent 的对接会变得非常容易，你手里用到的各项软件，都可以很方便的添加上智能体的能力。就像，我们现在用到的 `trae.ai`、`Cursor`，在以后 Ai Agent 基础能力成熟后，在结合 `Visual Studio Code` 给出软件对接标准协议，那么任何一个人都可以快速的搭建出一个智能体编码工具。除此之外，其他的软件也都会逐步提供出这样的能力。 + +扩展的思路分析完毕，小傅哥这次先带着大家了解下，draw.io 是怎么与 Ai 结合使用的。 + +>🧧 文末提供了小傅哥所有编程实战项目获取方式，一次加入即可获得19个已完结的和本次新开展的。 + +## 一、关于 draw.io + +draw.io 是一个用于绘制通用图表的 JavaScript 客户端编辑器。 + +官网：[https://www.drawio.com/](https://www.drawio.com/) +代码：[https://github.com/jgraph/drawio](https://github.com/jgraph/drawio) + +

+ +
+ +- 关于通信，就引入了 RPC 框架，而 Dubbo 就是其中的一个实现方式。 +- 那为啥用 Dubbo 呢？其实核心问题就一个，为了提高通信效率。因为 Dubbo 的底层通信是 Socket 而不是 HTTP 所以通信的性能会更好。同时 Dubbo 又有分布式的高可用设计，在一组部署了交易服务的实例宕机后，会被从注册中心摘除，之后流量会打到其他服务上。 + +## 二、要怎么使用 + +
+ +
+ +Dubbo 的使用分为2方，一个是接口的提供方，另外一个是接口的调用方。接口的提供方需要提供出被调用方使用接口的描述性信息。这个信息包括：接口名称、接口入参、接口出参，只有让调用方拿到这些信息以后，它才能依托于这样的接口信息做一个代理操作，并在代理类中使用 Socket 完成双方的信息交互。 + +所以你看上去调用 RPC 接口好像和使用 HTTP 也没啥区别，无非就是引入了 POM 配置，之后再配置了注解就可以使用了。但其实，它是把你的 Jar 当做代理的必要参数使用了。**本文也会介绍，具体是怎么代理的** + +## 三、使用的案例 + +对于编程的学习来说，其实最开始的那一下，不是搞明白所有原理，而是先让自己可以看到运行出来的效果。哎，之后就去分析原理，这样会舒服的多。 + +所以小傅哥这里提供了一套简单的 Dubbo 使用案例，只要你满足最基本的配置条件，就可以运行出效果； +1.

+ +
+ +- 你要先点击 root 下的 install 操作，这样就会自动构建了。 +- 如果你电脑配置有点低，也会出现一些`气人怪相`，比如就刷不进去，install 了也引用不了。记得要 clean 清空下，也可以直接到 maven 文件夹去清空。 + +### 2. 接口使用方 + +有些小卡拉米觉得前面的坑都扫干净了，就完事了。没有接下来还有坑，让你一搞搞一天，半夜也睡不好。 + +#### 2.1 POM 引入 + +```xml + + cn.bugstack + xfg-dev-tech-dubbo-api + 1.0-SNAPSHOT + +``` + +- POM 的配置，就是把 Jar 包给引用进来。因为 Dubbo 需要根据这个接口，做一个代理操作。**不引入，你代码就爆红啦！爆红啦！🌶** + +#### 2.2 消费配置 + +**源码**：`application.yml` + +```java +dubbo: + application: + name: xfg-dev-tech-dubbo + version: 1.0.0 + registry: + address: zookeeper://127.0.0.1:2181 +# address: N/A + protocol: + name: dubbo + port: 20881 +``` + +- 配置了 zookeeper 你就用第一个，代码中对应 `@DubboReference(interfaceClass = IUserService.class, version = "1.0.0")` +- 配置了 N/A 你就用第二个，代码中必须指定直连。`@DubboReference(interfaceClass = IUserService.class, url = "dubbo://127.0.0.1:20881", version = "1.0.0")` + +#### 2.3 代码配置 + +**源码**：`cn.bugstack.dev.tech.dubbo.consumer.test.ApiTest` + +```java +// 直连模式；@DubboReference(interfaceClass = IUserService.class, url = "dubbo://127.0.0.1:20881", version = "1.0.0") +@DubboReference(interfaceClass = IUserService.class, version = "1.0.0") +private IUserService userService; + +@Test +public void test_userService() { + UserReqDTO reqDTO = UserReqDTO.builder().userId("10001").build(); + Response resDTO = userService.queryUserInfo(reqDTO); + log.info("测试结果 req: {} res: {}", JSON.toJSONString(reqDTO), JSON.toJSONString(resDTO)); +} +``` + +**测试结果** + +```java +2023-07-08 15:37:22.291 INFO 62481 --- [ main] c.b.d.tech.dubbo.consumer.test.ApiTest : 测试结果 req: {"userId":"10001"} res: {"code":"0000","data":{"userAge":20,"userId":"10001","userName":"小傅哥"},"info":"成功"} +2023-07-08 15:37:22.324 INFO 62481 --- [tor-Framework-0] o.a.c.f.imps.CuratorFrameworkImpl : backgroundOperationsLoop exiting +``` + +- 如果不出啥意外，到这你就可以直接启动运行了。并看到测试结果。 +- 但别忘记了，你启动的时候，需要先启动 xfg-dev-tech-dubbo 让接口提供方跑起来。 + +## 四、原理的分析 + +都说 Jar 是提供可描述性信息的，对方才能代理调用。那么这个过程是怎么干的呢，总不能一问这个，就让小卡拉米们去手写 Dubbo 呀！所以小傅哥会通过最简单模型结构，让你了解这个 Dubbo 通信的原理，方便小卡拉米们上手。 + +
+ +
+ +- 如果所示，接口使用方，对接口进行代理。什么是代理呢，代理就是用一个包装的结构，代替原有的操作。在这个包装的结构里，你可以自己扩展出任意的方法。 +- 那么，这里的代理。就是根据接口的信息，创建出一个代理对象，在代理对象中，提供 Socket 请求。当调用这个接口的时候，就可以对接口提供方的，发起 Socket 请求了。 +- 而 Socket 接收方，也就是接口提供方。他收到信息以后，根据接口的描述性内容，进行一个反射调用。这下就把信息给请求出来，之后再通过 Socket 返回回去就可以了。 + +好，核心的原理就这么点。接下来，我们从代码中看看。 + +### 1. 接口反射 - 提供方 + +**源码**：`cn.bugstack.dev.tech.dubbo.trigger.socket.RpcServerSocket` + +```java +@Slf4j +@Service +public class RpcServerSocket implements Runnable { + + private ApplicationContext applicationContext; + + public RpcServerSocket(ApplicationContext applicationContext) { + this.applicationContext = applicationContext; + new Thread(this).start(); + } + + @Override + public void run() { + EventLoopGroup bossGroup = new NioEventLoopGroup(); + EventLoopGroup workerGroup = new NioEventLoopGroup(); + + try { + ServerBootstrap b = new ServerBootstrap(); + b.group(bossGroup, workerGroup) + .channel(NioServerSocketChannel.class) + .option(ChannelOption.SO_BACKLOG, 128) + .childHandler(new ChannelInitializer() { + @Override + public void initChannel(SocketChannel channel) { + channel.pipeline().addLast(new ObjectEncoder()); + channel.pipeline().addLast(new ObjectDecoder(ClassResolvers.cacheDisabled(null))); + channel.pipeline().addLast(new SimpleChannelInboundHandler>() { + + @Override + protected void channelRead0(ChannelHandlerContext channelHandlerContext, Map request) throws Exception { + // 解析参数 + Class clazz = (Class) request.get("clazz"); + String methodName = (String) request.get("methodName"); + Class[] paramTypes = (Class[]) request.get("paramTypes"); + Object[] args = (Object[]) request.get("args"); + + // 反射调用 + Method method = clazz.getMethod(methodName, paramTypes); + Object invoke = method.invoke(applicationContext.getBean(clazz), args); + + // 封装结果 + Map response = new HashMap<>(); + response.put("data", invoke); + + log.info("RPC 请求调用 clazz:{} methodName:{}, response:{}", clazz.getName(), methodName, JSON.toJSON(response)); + // 回写数据 + channelHandlerContext.channel().writeAndFlush(response); + } + }); + } + }); + + ChannelFuture f = b.bind(22881).sync(); + f.channel().closeFuture().sync(); + } catch (Exception e) { + e.printStackTrace(); + } finally { + bossGroup.shutdownGracefully(); + workerGroup.shutdownGracefully(); + } + } + +} +``` + +这段代码主要提供的功能包括： +1. Netty Socket 启动一个服务端。 +2. 注入 ApplicationContext applicationContext 用于在接收到请求接口信息后，获取对应的 Bean 对象。 +3. 根据请求来的 Bean 对象，以及参数的必要信息。进行接口的反射调用。 +4. 最后一步，就是把接口反射请求的信息，再通过 Socket 返回回去。 + +### 2. 接口代理 - 调用方 + +打开工程：[xfg-dev-tech-dubbo-test](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-dubbo-test) + +**源码**：`cn.bugstack.dev.tech.dubbo.consumer.config.RPCProxyBeanFactory` + +```java +@Slf4j +@Component("rpcProxyBeanFactory") +public class RPCProxyBeanFactory implements FactoryBean, Runnable { + + private Channel channel; + + // 缓存数据，实际RPC会对每次的调用生成一个ID来标记获取 + private Object responseCache; + + public RPCProxyBeanFactory() throws InterruptedException { + new Thread(this).start(); + while (null == channel) { + Thread.sleep(150); + log.info("Rpc Socket 链接等待..."); + } + } + + @Override + public IUserService getObject() throws Exception { + + ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); + Class[] classes = {IUserService.class}; + InvocationHandler handler = new InvocationHandler() { + @Override + public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { + + if (Object.class.equals(method.getDeclaringClass())) { + return method.invoke(this, args); + } + + Map request = new HashMap<>(); + request.put("clazz", IUserService.class); + request.put("methodName", method.getName()); + request.put("paramTypes", method.getParameterTypes()); + request.put("args", args); + + channel.writeAndFlush(request); + + // 模拟超时等待，一般RPC接口请求，都有一个超时等待时长。 + Thread.sleep(350); + + return responseCache; + } + }; + + return (IUserService) Proxy.newProxyInstance(classLoader, classes, handler); + } + + @Override + public Class getObjectType() { + return IUserService.class; + } + + @Override + public void run() { + EventLoopGroup workerGroup = new NioEventLoopGroup(); + try { + Bootstrap b = new Bootstrap(); + b.group(workerGroup) + .channel(NioSocketChannel.class) + .option(ChannelOption.AUTO_READ, true) + .handler(new ChannelInitializer() { + + @Override + protected void initChannel(SocketChannel channel) throws Exception { + channel.pipeline().addLast(new ObjectEncoder()); + channel.pipeline().addLast(new ObjectDecoder(ClassResolvers.cacheDisabled(null))); + channel.pipeline().addLast(new SimpleChannelInboundHandler>() { + + @Override + protected void channelRead0(ChannelHandlerContext channelHandlerContext, Map data) throws Exception { + responseCache = data.get("data"); + } + }); + } + }); + ChannelFuture channelFuture = b.connect("127.0.0.1", 22881).syncUninterruptibly(); + this.channel = channelFuture.channel(); + channelFuture.channel().closeFuture().syncUninterruptibly(); + } finally { + workerGroup.shutdownGracefully(); + } + } + +} +``` + +这段代码主要提供的功能包括： +1. 实现 `FactoryBean` 为的是把这样一个代理对象，交给 Spring 容器管理。 +2. 实现 Runnable 接口，并在接口中，创建 Netty 的 Socket 客户端。客户端中接收来自服务端的消息，并临时存放到缓存中。**注意 Dubbo 中这块的处理会复杂一些，以及请求同步响应通信，这样才能把各个接口的调动记录下来** +3. `getObject()` 对象中，提供代理操作。代理里，就可以自己想咋搞咋搞了。而 Dubbo 也是在代理里，提供了如此的操作，对接口提供方发送请求消息，并在超时时间内返回接口信息。因为反射调用，需要你`提供类`、`方法`、`入参类型`、`入参内容`，所以我们要把这些信息传递给接口提供方。 + +### 3. 服务测试 - 消费验证 + +- 启动 xfg-dev-tech-dubbo +- 测试 xfg-dev-tech-dubbo-test + +```java +@Resource(name = "rpcProxyBeanFactory") +private IUserService proxyUserService; + +@Test +public void test_proxyUserService(){ + UserReqDTO reqDTO = UserReqDTO.builder().userId("10001").build(); + Response resDTO = proxyUserService.queryUserInfo(reqDTO); + log.info("测试结果 req: {} res: {}", JSON.toJSONString(reqDTO), JSON.toJSONString(resDTO)); +} +``` + +**测试结果** + +```java +2023-07-08 16:14:51.322 INFO 74498 --- [ main] c.b.d.tech.dubbo.consumer.test.ApiTest : 测试结果 req: {"userId":"10001"} res: {"code":"0000","data":{"userAge":20,"userId":"10001","userName":"小傅哥"},"info":"成功"} +``` + +- 这里我们给 IUserService 注入一个自己代理好的对象，之后就可以调用验证了。 +- 好啦，到这我们就把关于 Dubbo 的事交代明白了，以上内容较多。小卡拉米需要细细的品味吸收！ diff --git a/docs/md/road-map/dump-mat.md b/docs/md/road-map/dump-mat.md new file mode 100644 index 000000000..15b94bd5e --- /dev/null +++ b/docs/md/road-map/dump-mat.md @@ -0,0 +1,239 @@ +--- +title: dump eclipse mat +lock: need +--- + +# Eclipse MAT 分析 Java heap space dump 日志 + +作者：小傅哥 +

Git 起源故事 + +讲到 Git 就不得不提一下 Linux，因为如果没有 Linux 也就没有 Git 的诞生，这里是有一段 **10天** 写出 Git 的故事！ + +众所周知，Linus 于 1991年 创建了开源的 Linux，从此 Linux 系统不断发展壮大。但 Linux 的壮大是靠全世界热心的开发者参与的，不过这么多人在世界各地为 Linux 编写代码，那代码是如何管理的呢？事实是，2002 之前，合并代码的操作都是 Linux 老爷子自己手动合并的！ + +但 2000 年的时候，不是已经 [SVN](https://zh.wikipedia.org/wiki/Subversion) 可以使用了吗？但 Linus 坚决反对 CVS、SVN 这些集中式的管理工具，不仅速度差还得联网操作。虽然有商用版的功能好一些，但这与 Linux 开源精神不符。所以 Linus 就不用，看人家这开源精神！ + +不过到了 2002年，Linux 都发展10年了，在这么手动的合并代码，让社区的兄弟也苦不堪言，强烈反对。为此，林纳斯·托瓦兹（Linus Torvalds）决定使用 BitKeeper 作为 Linux 内核主要的版本控制系统用以维护代码。BitKeeper 的东家 BitMover 公司，看 Linux 开源的不容易，授权 Linux 社区免费使用这个版本控制系统。 + +哈哈哈，但好景不长！2005年，安德鲁·垂鸠（Andrew Tridgell）写了一个简单程序，可以连接 BitKeeper 的仓库，BitKeeper 著作权拥有者拉里·麦沃伊认为安德鲁·垂鸠对 BitKeeper 内部使用的协议进行逆向工程，决定收回无偿使用 BitKeeper 的许可。Linux 内核开发团队与 BitMover 公司进行磋商，但无法解决他们之间的歧见。林纳斯·托瓦兹决定自行开发版本控制系统替代 BitKeeper ，以10天的时间编写出 git 第一个版本！—— 牛皮！ + +有了 Git 以后，GitHub 平台也于2007年10月1日开始开发。网站于2008年2月以beta版本开始上线，4月份正式上线。GitHub 里面的项目可以通过标准的 Git 命令进行访问和操作。—— 这就是 Linux、Git、Github 的故事。 + +## 2. 软件安装 + +Git 是一个软件工具，在使用前需要进行安装。 + +- 地址：[https://git-scm.com/downloads](https://git-scm.com/downloads) - `选择需要的版本下载` 网盘资源：[https://www.alipan.com/s/LqwsNfHRx54](https://www.alipan.com/s/LqwsNfHRx54) - `也提供了 Git 软件，在 dev-ops -> 环境 -> git 下` +- 演示：[https://learngitbranching.js.org/](https://learngitbranching.js.org/) - `可直接查看动画效果，引导式学习Git命令操作。` + +**配置代理** + +```java +git config --global http.proxy ip:port +git config --global https.proxy ip:port +``` + +- 如果你有代理地址可以配置 + +### 2.1 Mac + +```java +# 如果你没有 brew 命令，则需要先安装下；https://brew.sh/index_zh-cn +brew install git +``` + +### 2.2 Windows + +- [32-bit Git for Windows Setup](https://github.com/git-for-windows/git/releases/download/v2.41.0.windows.1/Git-2.41.0-32-bit.exe) +- [64-bit Git for Windows Setup](https://github.com/git-for-windows/git/releases/download/v2.41.0.windows.1/Git-2.41.0-64-bit.exe) + +### 2.3 Linux + +#### Debian/Ubuntu + +获取适用于您的 Debian/Ubuntu 版本的最新稳定版本 + +**如果没有安装npm可以安装** + +``` +# sudo apt update +# sudo apt install nodejs npm +# node -v +# npm -v +``` + +**安装git** + +``` +# apt-get install git +``` + +对于 Ubuntu，此 PPA 提供最新的稳定上游 Git 版本 + +``` +# add-apt-repository ppa:git-core/ppa +# apt update; apt install git +``` + +#### Centos + +```java +sudo yum install git +``` + +## 3. 配置账户 + +当你拿到一个Git的仓库（Github、Gitcode、Gitee、GitLab），让你克隆（git clone）代码的时候，不要`虾呵呵`的上去就点个zip下载。 + +

+ +
+ +- 像是 Mac 电脑会自动默认的配置好 IntelliJ IDEA Git 直接使用即可，如果你的电脑在 IntelliJ IDEA 打开工程后，提示没有 Git 则可进入设置手动配置。 +- 配置后，点击 Test 可以测试出 Git 的版本。 + +### 5.2 检出代码 + +#### 5.2.1 方式1；打开工程前 + +
+ +
+ +#### 5.2.2 方式2；打开工程后 + +
+ +
+ +- 打开工程后，也可以通过菜单栏中的 Git 进行检出操作。 + +### 5.3 图形界面 + +#### 5.3.1 分支使用 + +
+ +
+ +#### 5.3.2 提交代码 + +
+ +
+ +#### 5.3.3 查看记录 + +
+ +
+ +#### 5.3.4 查看对比 + +
+ +
+ +- 这个代码对比非常适合代码评审，也可以用于自己学习代码。可以知道任意两个分支的代码差异，也就知道了代码上一次是什么样，这一次是做了什么开发。 + +#### 5.3.5 合并分支 + +在公司中很多时候是大家一起在一个工程开发代码，那么这个时候就会涉及合并代码的。如果有多人共同开发一个接口方法，就会在合并的时候产生冲突。所以要特别注意。 + +注意，📢在Git中，`merge`和`rebase`是两种用于合并分支变更的方法。每种方法都有其特定的用途和行为： + +Merge + +- **概念**: `merge`命令用于将一个分支的更改合并到当前分支，通常会生成一次新的合并提交（commit），从而保留分支历史。 +- **历史记录**: 使用`merge`会保留所有开发历史记录，包括分支点，这使得历史记录图呈现出一个分叉和合并的树状结构。 +- **使用场景**: + - 当你想保留完整的历史记录，了解如何以及何时进行了分支。 + - 通常用于将分支合并到主分支(如`main`或`master`)时，以保留分支的历史上下文。 +- **命令**: + ```bash + git checkout main + git merge feature-branch + ``` + +Rebase + +- **概念**: `rebase`命令用于重新定位一系列的提交，可以将分支上的更改申请到另一分支的顶端，因而能得到更线性的历史。 +- **历史记录**: Rebase重新写了提交历史（改变了提交的父提交），这会导致更线性的提交历史，从而更清晰，但会丢失分支合并信息。 +- **使用场景**: + - 当你希望提交历史更加简洁和线性。 + - 合并特性分支到主分支前用以避免杂乱的分支合并历史。 + - 需要小心在共享分支上使用，因为重写的提交历史会影响他人。 +- **命令**: + ```bash + git checkout feature-branch + git rebase main + ``` + +选择何时使用 + +- **Merge**适合用于保持完整的提交历史，不改变现有提交的哈希。 +- **Rebase**适合用于清理提交历史，通常在提交尚未推送至共享存储库时使用。 + +一般情况下，对于已对外分享的分支，尤其是共享存储库中的`main`或`master`分支，尽量避免使用`rebase`。而对于个人开发的特性分支，`rebase`可以帮助维护一个清晰的提交历史。 + +**普通合并** + +
+ +
+ +- 在实际的开发中，大家承接新的需求，会从master拉一个新的分支。拉取后，开始编写代码，完成开发后提交。 +- 之后切换到master分支，通过把自己的开发的分支合并回master分支进行提交。 +- 注意：如果多人开发，同时修改一个类，可能会引起合并冲突，这个审核要点开类，查看冲突进行合并，不要把自己和他人的代码合并丢失。 + +**冲突合并** + +
+ +
+ +1. 选择，你要从哪个分支合并到 test 分支。右键选择 Merge into test +2. 如果你合并到test分支的代码，有其他人也在同一行做了改变或者格式化了代码，就会弹出一个合并冲突。这个时候你需要点 Merge 进行合并。 +3. 在点击 Merge 后，你会看到具体冲突的代码是什么，你可以有选择的从左右合并到中，最后点击 Apply。这个时候要注意不要把让别人的代码合并丢喽。 +4. 合并完的代码，不要直接 push，你要先本地 install 看是否可以打包。以及如果可以运行的话，可以本地先跑一下。 最后 push 提交合并代码即可。 + +#### 5.3.6 回滚分支 + +回滚提交和回滚push + +
+ +
+ +如果出现了合并代码冲突后，丢失了代码，那么这个时候一般要进行回滚操作，重新合并。 + +虽然 Git 提供了回滚代码的功能，但一定要谨慎使用。怎么谨慎？第一个谨慎就是 push 的代码一定确保可以构建和运行，否则不要 push！第二个谨慎是要回滚代码，需要和团队中对应的伙伴打招呼，避免影响别人测试或者上线。 + +
+ +
+ +1. 先选择要在哪个分支的哪次提交上进行回滚。这里选择的是 test 分支上的提交进行回滚。 +2. 这里选择 Hard 回滚。因为我们所有的都是合并到 test 分支，所以 test 分支丢失也没问题。可以重新合并。但要和同组伙伴提前说明。 +3. 回滚后，你会看到代码只剩下从回滚往下的提交内容了。 +4. 回滚后，你不能直接 push 提交了，这个之后会报错；`fast-forward` 因为此时本地分支落后于远程分支。 +5. 所以要通过 `git push origin HEAD --force` 进行强制提交。或者你可以把 test 的远程分支删掉，之后在提交。 + +## 6. 提交工程 - IntelliJ IDEA + +那么首次创建的工程怎么提交到代码库呢？🤔 + +### 6.1 创建本地仓库 + +
+ +
+ +- Create Git repository 创建一个本地的暂存库。你可以把开发的内容暂时提交到本地仓库中。 + +### 6.3 提交本地代码 + +
+ +
+ +- 把本地仓库提交到本地代码库待提交列表中。 +- 后续你在创建的代码，会默认自动加入进来。*如果你是通过打开文件夹复制进去的，不会被添加，需要手动 +Add* +- 添加后就可以参考 5.3 中的操作提交代码了。 + +### 6.4 创建远程仓库 + +你可以选择 GitHub/GitCode/Gitee/GitLab 任意地方创建自己的工程库。教程； +- [https://bugstack.cn/md/road-map/github.html](https://bugstack.cn/md/road-map/github.html) +- [https://bugstack.cn/md/road-map/gitcode.html](https://bugstack.cn/md/road-map/gitcode.html) +- [https://bugstack.cn/md/road-map/gitee.html](https://bugstack.cn/md/road-map/gitee.html) + +
+ +
+ +### 6.5 推送本地工程 + +
+ +
+ +
+ +
+ +- 最后推送完成就可以看到自己的代码进入仓库中了！ + +## 7. 操作界面 - git-gui + +Git 附带了用于提交 ( [git-gui](https://git-scm.com/docs/git-gui) ) 和浏览 ( [gitk](https://git-scm.com/docs/gitk) ) 的内置 GUI 工具，但也有一些第三方工具可供用户寻求特定于平台的体验。 + +
+ +
+ +- Git 提供了操作的客户端界面，你可以按需下载使用。 +- 地址：[https://git-scm.com/docs/git-gui](https://git-scm.com/docs/git-gui) + +## 8. 分支命名 + +不同公司中对Git的使用分支命名规范也略有差异，不过整体都会分为；`上线`、`预发`、`开发`、`测试`，这样几个分支。如图是一种比较简单使用的拉取分支方式。 + +
+ +
+ +- master/main 作为主分支，不可直接修改代码代码，只能从分支合并到主分支进行进行提交。同时，master 分支的合并需要进行审批，审批后才能合并。 +- 开发前，先从 master 分支，拉一个开发分支。`2024/10/11/xfg-xxx` 使用带有斜线的分支命名会自动创建文件夹，对于多人开发的项目，可以直接归档。 +- 后开发，也就是研发已经完成了本地的验证。进行测试时，可以把研发的开发分支合并到 test 分支，提交、部署、测试。遇到测试bug，需要回到可发分支修改代码，之后合并到 test 分支部署验证。 +- pre/release 预发分支，用于测试完成后，把研发的开发分支合并到预发分支进行预发上线，上线后测试人员进行验证。最终完成验证后，把开发分支合并到 master 分支，并需要由架构师对合并代码审批通过。最后进行上线开量验证。 +- 如果是修复bug的，可以添加一个 `fix-用户名缩写-具体功能` + +## 9. 提交规范 + +保持一个标准的统一的规范提交代码，在后续的评审、检查、合并，都会非常容易处理。 + +
+ +
+ +**提交规范**：`type:【需求名】desc #id` 如：`feat:【抽奖算法】O1、Ologn 时间复杂度算法实现 #需求id（github pr/行云等会有自动关联）` *参考Commit message 规范* + +```java +# 主要type +feat: 增加新功能 +fix: 修复bug + +# 特殊type +docs: 只改动了文档相关的内容 +style: 不影响代码含义的改动，例如去掉空格、改变缩进、增删分号 +build: 构造工具的或者外部依赖的改动，例如webpack，npm +refactor: 代码重构时使用 +revert: 执行git revert打印的message + +# 暂不使用type +test: 添加测试或者修改现有测试 +perf: 提高性能的改动 +ci: 与CI（持续集成服务）有关的改动 +chore: 不修改src或者test的其余修改，例如构建过程或辅助工具的变动 +``` + +> 前提通知，谨慎回滚。如果是回滚 Master 更要特别小心，别把工作回滚丢了。 + +## 10. 操作手册 + +- 文档：[https://git-scm.com/book/zh/v2](https://git-scm.com/book/zh/v2) - `可以直接对照着操作，练习命令` +- PDF：[https://github.com/progit/progit2-zh/releases/download/2.1.62/progit.pdf](https://github.com/progit/progit2-zh/releases/download/2.1.62/progit.pdf) +- 演示：[https://learngitbranching.js.org/](https://learngitbranching.js.org/) - `可直接查看动画效果，引导式学习Git命令操作。` + +--- + +

+ +
+ +这些免费的不错的大模型（LLM），也都是有对应的频次和最大出入/输出token的限制。虽然不会让咱们玩命的调用测试。但在程序开发初期，对于单个功能的验证还是非常方便的。接下来，小傅哥就给大家演示下，关于 Github 免费提供的大模型如何配置使用。 + +## 一、模型说明 + +### 1. 官网地址 + +官网：[https://github.com/marketplace?type=models](https://github.com/marketplace?type=models) + +

+ +
+ +- 环境；jdk 1.8、Maven 3.6.x、Docker 环境 +- 代码；在 xfg-dev-tech-grafana 测试工程中提供了测试代码和环境安装 + +### 1. 配置修改 + +
+ +
+ +- 首先，你需要打开 prometheus.yml 修改监控采集应用的IP地址。这个配置还可以监控例如 MySQL 和其他应用。 + +### 2. 安装监控 + +文件：`docker-compose.yml` + +```java +version: '3' +# 执行脚本；docker-compose -f docker-compose.yml up -d +# 拷贝配置；docker container cp grafana:/etc/grafana/ ./docs/dev-ops/ +services: + # 数据采集 + prometheus: + image: bitnami/prometheus:2.47.2 + container_name: prometheus + restart: always + ports: + - 9090:9090 + volumes: + - ./etc/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml + # 监控界面 + grafana: + image: grafana/grafana:10.2.0 + container_name: grafana + restart: always + ports: + - 4000:4000 + depends_on: + - prometheus + volumes: + - ./etc/grafana:/etc/grafana +``` + +
+ +
+ +
+ +
+ +- 这是 docker compose 执行脚本，如果你本地已经安装了 Docker 可以直接执行 安装即可。 +- 注意；如果你是生产使用，则需要修改 `etc/grafana/grafana.ini` 中 datasources 为 mysql 这样在后面迁移的时候也会非常容易。 + +### 3. 监控配置 + +- 安装完监控环境以后，可以先打开 Grafana 地址：[http://127.0.0.1:4000](http://127.0.0.1:4000) - `admin/admin` + +- 地址：[http://127.0.0.1:4000/dashboards](http://127.0.0.1:4000/dashboards) - 打开仪表盘，导入监控面板配置。 + +
+ +
+ +
+ +
+ +- 打开导入面板后，把案例工程中的 JSON 复制到导入面板的 JSON 里，点击 Load 这样就配置进去了。 +- 不过这会你还看不见数据，因为工程还没有启动，没有往里写入数据。 + +## 三、测试应用说明 + +### 1. 熔断配置 + +```pom + + com.netflix.hystrix + hystrix-javanica + 1.5.18 + +``` + +- 这个熔断的组件，不需要引入 SpringCloud 一堆的东西，使用起来更加容易。 + +```java +@Configuration +public class HystrixConfig { + + @Bean + public HystrixCommandAspect hystrixCommandAspect() { + return new HystrixCommandAspect(); + } + +} +``` + +- 引入 POM 后，添加 HystrixConfig 熔断配置。 + +### 2. 接口配置 + +这里小傅哥提供了2个接口，一个普通的查询数据接口，一个是 OpenAi 中服务的给前端异步响应结果的接口。尤其是 OpenAi 异步接口，我们在实际使用的时候，也总会有超时熔断，所以这里给大家添加上。 + +#### 2.1 普通接口 + +```java +/** + * curl http://localhost:8091/api/hystrix/query_order_info + */ +@HystrixCommand(commandProperties = { + @HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "50") +}, fallbackMethod = "queryOrderInfo_error" +) +@RequestMapping(value = "query_order_info", method = RequestMethod.GET) +public String queryOrderInfo() throws InterruptedException { + new CountDownLatch(1).await(); + return "您的订单信息查询完毕"; +} + +private String queryOrderInfo_error() throws InterruptedException { + return "Fallback Hello"; +} +``` + +- 测试过程中，超时熔断时间，可以设置的较大一些，也可以先不添加超时熔断的注解。 + +#### 2.2 异步接口 + +```java +/** + * curl http://localhost:8091/api/hystrix/stream + */ +@HystrixCommand(commandProperties = { + @HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "150") +}, fallbackMethod = "stream_error" +) +@RequestMapping(value = "/stream", method = RequestMethod.GET) +public ResponseBodyEmitter stream(HttpServletResponse response) throws Exception { + response.setContentType("text/event-stream"); + response.setCharacterEncoding("UTF-8"); + response.setHeader("Cache-Control", "no-cache"); + ResponseBodyEmitter emitter = new ResponseBodyEmitter(); + emitter.send("异步响应"); + new Thread(() -> { + for (int i = 0; i < 200; i++) { + try { + emitter.send("hi xfg-dev-tech-grafana\r\n" + i); + Thread.sleep(250); + } catch (Exception e) { + throw new RuntimeException(e); + } + } + emitter.complete(); + }).start(); + return emitter; +} + +public ResponseBodyEmitter stream_error(HttpServletResponse response) throws IOException { + response.setContentType("text/event-stream"); + response.setCharacterEncoding("UTF-8"); + response.setHeader("Cache-Control", "no-cache"); + ResponseBodyEmitter emitter = new ResponseBodyEmitter(); + emitter.send("Err"); + emitter.complete(); + return emitter; +} +``` + +- 另外一个是一步响应接口，如果响应时间较长，则进入超时熔断方法中。 + +## 四、服务压测验证 + +### 1. 配置信息 + +**application.yml** + +```yml +server: + port: 8091 + # 1核2G内存，可默认配置 200；4核8G内存【accept-count=1000、max-threads=800、max-connections=10000】，线程数经验值800。线程池过大，cpu调度会消耗大量时间 + tomcat: + mbeanregistry: + enabled: true + max-connections: 20 # 最大连接数 + threads: + max: 20 # 设定处理客户请求的线程的最大数目，决定了服务器可以同时响应客户请求的数,默认200 + min-spare: 10 # 初始化线程数,最小空闲线程数,默认是10 + accept-count: 10 # 等待队列长度 +``` + +- 我们在 YML 文件中指定了 tomcat 的连接数配置为 20 个，处理线程最多也是20个。 +- 同时还添加了监控空你暴露为true，这样 Grafana 才能监控到。 + +### 2. 压测工具 + +压测工具有很多，包括；[JMeter、ApacheBench、Siege](https://bugstack.cn/md/road-map/jmeter.html) 小傅哥已经在前面写过文章，也可以去参考使用。 + +不过这里为了让大家更加简单的压测下，小傅哥使用了 ApiPost 工具自带的压测，这样不需要自己再安装其他工具就可以简单压测下了。 + +
+ +
+ +- 你只要把2个接口配置到 ApiPost 就可以用一键压测工具进行压测。 + +### 3. 压测观察 + +
+ +
+ +- 这里小傅哥压测了下接口 `http://localhost:8091/api/hystrix/stream` 接口。因为这个接口设置了超时，可以看见，快速的就把连接数给占满了。 +- 所以如果你的应用配置的 Tomcat 连接数不合理，之后接口又容易超时，超时后又没有熔断，那么很容易就会把你的服务拖垮。很多新人在做一些对外的应用时，如果没有注意到这些，那么也是很容易宕机的。 diff --git a/docs/md/road-map/guava.md b/docs/md/road-map/guava.md new file mode 100644 index 000000000..e069bde8c --- /dev/null +++ b/docs/md/road-map/guava.md @@ -0,0 +1,143 @@ +--- +title: guava +lock: need +--- + +# Guava 使用 + +作者：小傅哥 +

+ +
+ +不少伙伴问为啥自研，😂 但其实从我进入互联网大厂，核心的分布式技术框架，几乎就全部都是公司自研。从 rpc、mq、缓存组件（配合redis集群）、配置中心、分库分表、任务调度、全链路监控，再到我们提到的 API 网关，全部的都是自研。 + +后来才知道，因为之前用过一些开源组件，在流程承载方面发生过重大事故。因为是开源的组件，没法对每一个细节进行把控。而全部的自研，就会有非常强的把控力度，各个细节实现都可以做具体的优化方案，同时所有的组件自研，还可以更好的串联起来使用。另外还有一个点，就是这些开源的组件，更容易被攻击，如果有漏洞要升级，那公司全升级一遍的成本，不亚于一次大规模裁员的赔偿！当然，一些中小厂还是用市面开源的就好，因为自研的成本并不低！ + +那么为了让大家更好的了解下大厂的API，今天我们就来体验一款大厂开发的元原生API网关。有了这样一个学习，在看API网关项目，也会更清楚自己在做什么。 + +- 官网：[https://higress.io/](https://higress.io/) +- 源码：[https://github.com/alibaba/higress](https://github.com/alibaba/higress) +- 部署：[https://github.com/higress-group/higress-standalone](https://github.com/higress-group/higress-standalone) - `独立运行版，用于测试` +- 案例：[https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-higress](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-higress) - `部署测试` + +>Higress 是一套比较庞大的工程，为了让大家可以方便的体验到，小傅哥会教给大家怎么做一个独立的部署和配置网关负载。此外文末还提供了基于 Netty 的 API网关学习教程。 + +## 一、Higress 介绍 + +Higress 是基于阿里内部两年多的 Envoy Gateway 实践沉淀，以开源 [Istio](https://github.com/istio/istio) 与 [Envoy](https://github.com/envoyproxy/envoy) 为核心构建的云原生 API 网关。Higress 实现了安全防护网关、流量网关、微服务网关三层网关合一，可以显著降低网关的部署和运维成本。 + +

+ +
+ +- 服务来源支持非常多的类型，包括；Nacos、Zookeeper、Consul、Eureka、固定地址、DNS 域名。这里小傅哥选择固定地址配置。 +- 分别配置了 nginx-01、nginx-02 这样我们配置路由的时候可以负载到这2个地址。 + +### 2. 路由配置 + +路由配置的作用就是指定你通过网关地址负载到对应的目标服务上，这里我们会让 http://117.72.37.243/api/ 请求负载到2个 nginx 上。 + +

+ +
+ +整个**API网关**设计核心内容分为这么五块； + +- `第一块`：是关于通信的协议处理，也是网关最本质的处理内容。这里需要借助 NIO 框架 Netty 处理 HTTP 请求，并进行协议转换泛化调用到 RPC 服务返回数据信息。 +- `第二块`：是关于注册中心，这里需要把网关通信系统当做一个算力，每部署一个网关服务，都需要向注册中心注册一个算力。而注册中心还需要接收 RPC 接口的注册，这部分可以是基于 SDK 自动扫描注册也可以是人工介入管理。当 RPC 注册完成后，会被注册中心经过AHP权重计算分配到一组网关算力上进行使用。 +- `第三块`：是关于路由服务，每一个注册上来的Netty通信服务，都会与他对应提供的分组网关相关联，例如：wg/(a/b/c)/user/... a/b/c 需要匹配到 Nginx 路由配置上，以确保不同的接口调用请求到对应的 Netty 服务上。PS：如果对应错误或者为启动，可能会发生类似B站事故。 +- `第四块`：责任链下插件模块的调用，鉴权、授信、熔断、降级、限流、切量等，这些服务虽然不算是网关的定义下的内容，但作为共性通用的服务，它们通常也是被放到网关层统一设计实现和使用的。 +- `第五块`：管理后台，作为一个网关项目少不了一个与之对应的管理后台，用户接口的注册维护、mock测试、日志查询、流量整形、网关管理等服务。 + +>项目学习地址：[https://bugstack.cn/md/assembly/api-gateway/api-gateway.html](https://bugstack.cn/md/assembly/api-gateway/api-gateway.html) \ No newline at end of file diff --git a/docs/md/road-map/http.md b/docs/md/road-map/http.md new file mode 100644 index 000000000..ff004b0fc --- /dev/null +++ b/docs/md/road-map/http.md @@ -0,0 +1,279 @@ +--- +title: http +lock: need +--- + +# HTTP 框架使用和场景实战 - 结合ChatGLM自动回帖！ + +作者：小傅哥 +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +本文的宗旨在于通过简单干净实践的方式，向读者介绍一款基于内存的分布式SQL数据库Apache Ignite的部署、使用和性能测试。 + +那有了Redis这样优秀的NoSql数据库，为啥还会用到Apache Ignite呢？ + +不知道你是否有想过一个事情，就是Redis这样的内存数据库，如果能支持SQL语句，是不是就更牛了。这样一来本身存在MySQL数据库里的数据，就可以原封不动的封到内存中使用。既保留了原有的业务逻辑，又使用上了内存读取高性能。 + +所以，它来了。Apache Ignite是一个兼容ANSI-99、水平可扩展以及容错的分布式SQL数据库，作为一个SQL数据库，Ignite支持所有的DML指令，包括SELECT、UPDATE、INSERT和DELETE，它还实现了一个与分布式系统有关的DDL指令的子集。Ignite的一个突出特性是完全支持分布式的SQL关联，Ignite支持并置和非并置的数据关联。并置时，关联是在每个节点的可用数据集上执行的，而不需要在网络中移动大量的数据，这种方式在分布式数据库中提供了最好的扩展性和性能。 + +
+ +
+ +本文涉及的工程： + +- xfg-dev-tech-ignite：[https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-ignite](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-ignite)- `docs/dev-ops 提供了 mysql、ignite 安装脚本，和数据初始化操作。` +- 官网站点：[https://ignite.apache.org/](https://ignite.apache.org/) - `官网 docs 可以阅读安装和使用` +- 中文文档：[https://ignite-service.cn/doc/2.7.0/sql/](https://ignite-service.cn/doc/2.7.0/sql/) - `这是一个 Ignite 的中文站点` +- 管理工具：[DBeaver](https://dbeaver.io/download/) - `安装最新版，直接可以连接 Ignite 数据库` + +## 一、案例说明 + +本案例中为了对比MySQL和Ignite的性能差异，以及如何同时使用两套数据库，这里小傅哥会在一个工程中分别配置出不同的数据库对应数据源的创建和MyBatis的配置用。如果说你做过小傅哥的 [DB-Router](https://bugstack.cn/md/road-map/db-router.html) 组件开发，那么也可以在组件中添加对Ignite内存数据库的路由配置。这样的使用会更加方便，也可以自动的通过注解来切换数据源的使用。 + +
+ +
+ +- SpringBoot应用的yml配置，本身默认是配置一个数据源的。但我们这里需要把Ignite也配置出数据源并让它可以结合MyBatis进行使用。所以需要做一点编码的扩展使用。`具体可以参考源码` +- 与此同时还需要考虑对 Dao、Mapper 分不同的路径进行加载使用。因为本身来说，他们就是一套东西的不同数据源使用方式。 + +## 二、环境安装 + +在安装执行 docker-compose.yml 脚本之前，你需要先在本地安装 [docker](https://bugstack.cn/md/road-map/docker.html)之后 IntelliJ IDEA 打开 docker-compose.yml 文件，如图操作即可安装。 + +
+ +
+ +- 在 docker-compose.yml 中会先安装 MySQL 并执行 sql 文件夹里的 SQL 语句初始化数据库表。之后会安装 Ignite 环境，安装后需要用到 [DBeaver](https://dbeaver.io/download/) 连接使用。同时 compose 中还安装了一个 ApacheBench 压测工具。 + +## 三、连接配置 + +首先确保你已经安装过 [DBeaver](https://dbeaver.io/download/) ，之后就可以连接和创建表了。 + +### 1. 选择 Ignite + +

+ +
+ +- 这里提供了 Ignite、MySQL 的 HTTP 访问接口，分别进行压测。 + +### 1. Ignite 压测 + +- 初始化ID值：`ab -c 1 -n 1 http://127.0.0.1:8091/api/ignite/start` +- 写入数据：`ab -c 20 -n 50000 http://127.0.0.1:8091/api/ignite/insert` +- 随机加载内存1000条数据：`ab -c 20 -n 1000 http://127.0.0.1:8091/api/ignite/cacheData` +- 根据加载到内存的数据查询Ignite：`ab -c 20 -n 1000 http://127.0.0.1:8091/api/ignite/selectByOrderId` - 记得给 OrderId 加索引 + +
+ +
+ +### 2. MySQL 压测 + +- 初始化ID值：`ab -c 1 -n 1 http://127.0.0.1:8091/api/ignite/start` +- 写入数据：`ab -c 20 -n 50000 http://127.0.0.1:8091/api/ignite/insert` +- 随机加载内存1000条数据：`ab -c 20 -n 1000 http://127.0.0.1:8091/api/ignite/cacheData` +- 根据加载到内存的数据查询MySQL：`ab -c 20 -n 1000 http://127.0.0.1:8091/api/ignite/selectByOrderId` - 记得给 OrderId 加索引 + +
+ +
+ +--- + +**综上**，Ignite 略胜一筹，确实纯内存的数据库会更快一些。也适合在一些需要内存计算的场景中，并且不改变MySQL表结构的情况下，做一些优化的是使用。 \ No newline at end of file diff --git a/docs/md/road-map/intellij-idea-remote-jvm-debug.md b/docs/md/road-map/intellij-idea-remote-jvm-debug.md new file mode 100644 index 000000000..185282c0f --- /dev/null +++ b/docs/md/road-map/intellij-idea-remote-jvm-debug.md @@ -0,0 +1,225 @@ +--- +title: IntelliJ IDEA Remote JVM Debug +lock: need +--- + +# IntelliJ IDEA Remote JVM Debug - 本地远程调试服务器运行代码 + +作者：小傅哥 +

+ +
+ +**你的代码本地没法启动！** + +其实并不是所有的工程代码，都能本地启动运行的。尤其复杂的工程，与外部对接非常多，甚至还有一些是风险控制的问题，本地是不能启动直接调用的。也就是控制研发人员，不允许本地程序调用其他程序的接口。那么对于这样的工程，研发的自测就要通过编写 [mock](https://bugstack.cn/md/road-map/mock.html) 方式进行单元化测试。 + +不过这里会有一个问题，单元化的测试，mock 的数据是不会随着外部所有程序的调整动态的变更的，而是随着研发编写需求，一次写好后，后续如果这个功能没有被调整，那么 mock 测试也不会在调整了。同时还因为 mock 覆盖的场景不全，不知道引入的外部那么多接口都有哪些新增的逻辑。因而，你可能本地运行没问题，但部署到测试环境，就会有一些不缺性的报错。 + +对于这里的报错，当你没有 debug 手段的时候，就要把前后的报错数据，都要复制到本地，通过 mock 的方式验证程序逻辑，一点点排查。不过，这个过程也要花费好长时间，尤其是一些复杂的逻辑与外部交互又非常多的时候，调试起来很耗费时间。 + +所以，程序员👨🏻‍💻对于实在难以调试的代码，还有一种方式就是远程调试。把代码部署到服务器，通过请求服务器的接口，本地的 IntelliJ IDEA 打开的工程，就可以调试对应的运行数据。可以非常高效的解决 bug！ + +接下来，小傅哥就带着大家做一个这样的案例。如果你是一个新手小白，就更有必要学习一下这样的手段了。 + +> 🧧 文末还提供了17个实战项目，全套的文档、视频、代码，都可以获取。还有非常清晰的学习路线！嘎嘎冲！ + +## 一、测试工程 + +这里小傅哥为你准备好了一个测试工程，你可以直接下载验证。 + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +如果在面试的时候，面试官问你DDD是什么，你怎么解释？是不是感觉DDD的资料也看了不少，但好像还没有一个定义给DDD，所以炸一听这有的问题的时候，还真有点慌。 + +
+ +
+ +那DDD是什么呢？🤔 + +**关于DDD是什么，在维基百科有一个明确的定义。"Domain-driven design (DDD) is a major software design approach." 也就是说DDD是一种主要的软件设计方法。而软件设计涵盖了；范式、模型、框架、方法论。** + +- 范式（paradigm）指的是一种编程思想。 +- 模型（model）指的是对现实世界或者问题的抽象描述。 +- 框架（framework）指的是提供了一系列通用功能和结构的软件工具。 +- 方法论（methodology）指的是一种系统的、有组织的解决问题的方法。 + +所以，DDD不只是只有指导思想，伴随的DDD的还包括框架结构分层。但说到底，这些仍然是理论讨论。在没有一个DDD落地项目物参考下，其实大部分码农是没法完成DDD开发的。所以小傅哥今年花费了5个月假期/周末的时间，完成的《DDD简明开发教程》，帮助大家落地DDD编码。 + +>文末可以获取到基于DDD架构开发的实战项目。 + +## 一、能学到啥 + +因为DDD本身有很多的方法论，指导着框架结构的设计，从而控制着工程模块间的平衡。这种平衡的约束，起到了很好的防腐作用，天然的控制了职责的分离。不过也因为有了这些约束，很多初次上手DDD的研发伙伴不知道怎么下手了。所以以下这些内容，则是帮你进入DDD开发； + +1. 为你，提供整个DDD简单版、DDD标准版，脚手架使用，并配合提供 docker compose 一键开发环境安装。这样你再使用的时候就可以更加容易进入了。 +2. 为你，深度讲解DDD分层结构、DDD全模块调用链路、MVC2DDD的升级关闭和对比、DDD领域模型(账户/支付)的设计和编码。 +3. 为你，拆分独立案例，讲解应用启动、配置加载、各类技术框架和分布式技术栈，在DDD分层结构下具体到每个模块中的使用手段。如；MyBatis、Dubbo、RocketMQ、Redis、Zookeeper、Sharding-JDBC、XXL-Job等。—— 这些案例都来自于业务场景中的常用使用方式，非常具有代表性。 +4. 为你，讲解工程开发中常用类库和工程的测试压测处理方案。如；Guava、OKHTTP、Mock、JMeter、AB、Siege等。这些东西是为了更好的完成代码交付。 +5. 为你，工程开发最后的阶段，提供；Docker、Portainer 云服务操作，以及包括对工程的全链路监控学习。此外基础的 IntelliJ IDEA、Maven、Git、Github/Gitcode/Gitee，的使用教程。 + +以上，这些内容的学习，可以让你既掌握DDD架构的开发使用，又能快速的学会各项基础技术栈和分布式技术栈的运用，还能学习到监控、压测、云服务操作。可以说是一举多得！嘎嘎强！ + +## 二、小册演示 + +可以这么说，这套DDD的小册课程是非常基础入门，又覆盖得极其全面。哪怕是小白研发，也能完全跟着走下来。既有文章又有视频，每一个小知识点都是一个独立的案例讲解。以下就是DDD小册内的一些截图，可以参考看下。 + +### 1. 工程结构模型 + +

DDD难落地，不是DDD有多难，是没经验的人做DDD，不清楚范式、模型、框架、方法论，只能抱着理论给团队伙伴讲，并且在很多细节使用上没法把控，导致越来越难维护。`上DDD==上一坨屎`。 +3. 不是非得多复杂的系统才能用DDD，简单系统使用DDD，也会更好的维护。因为很多没彻底做过DDD的开发的，甚至并不知道domain的核心是什么，眼里只有聚合、聚合、聚合。 +4. 能在MVC结构下写代码不错的人，到DDD可以写的更好。DDD只是软件设计方法的改变，但不决定原本代码垃圾的人，换个结构代码就牛逼了。 +5. 不具备DDD结构设计和调整的研发，会生搬硬套DDD。所以没法根据自身业务需求调整分层的结构，如在domain领域编排复用极低的场景，可以去掉application/case层，这样会减少大量的对象转换。 +6. 千万别说设计模式没用，好好看看一些高质量的框架源码，对于；分治、抽象、知识(设计原则、设计模式)的运行，是有多好。没用设计模式的DDD，就像没有家具的四居室，卧室里可以安装马桶。厨房里可以放个床。 + +## 五、加入学习 + +注意📢，DDD开发小册为小傅哥提供的免费学习资料，提供了基础内容的讲解。此外加入小傅哥【星球：码农会锁】还有DDD应用级实战项目课程，通过这些课程的实操，对实际业务场景进行架构、设计、编码、上线，更加扎实的掌握DDD领域驱动设计的运用。项目体验地址：[https://gaga.plus](https://gaga.plus) - 小傅哥为星球项目部署的演示平台。 + +- 【免费】- DDD开发小册；[https://bugstack.cn/md/road-map/road-map.html](https://bugstack.cn/md/road-map/road-map.html) +- 【付费】- DDD实战项目；[https://t.zsxq.com/14NGs0bGU](https://t.zsxq.com/14NGs0bGU) - `OpenAi 大模型应用`、`Lottery 分布式抽奖`、`Api网关`、`IM通信`等 + +>这样一套全体系的实战项目，放在一些平台售卖，至少都是几百块。但小傅哥的星球，只需要100来块钱，就可以获得几千元的学习项目！ + +>[🧧加入学习](https://bugstack.cn/md/zsxq/other/join.html) + +小傅哥的【星球：码农会锁】，是一条龙🐲成体系的学习，因为这些内容都是小傅哥原创编写，所以学习起来的衔接性会非常强，有紧有收、循序渐进！欢迎加入，可别错过！ + +

+ +
+ +- 配置了Git仓库的连接凭证，才能从Git仓库拉取代码。 +- 如果你还需要操作如 ssh 也需要配置凭证。 + +## 三、新建任务 + +一个任务就是一条构建发布部署项目的操作。 + +### 1. 配置任务 + +
+ +
+ +``` +xfg-dev-tech-jenkins +``` + +### 2. 配置Git + +
+ +
+ +```java +# 你可以 fork 这个项目，到自己的仓库进行使用 +https://gitcode.net/KnowledgePlanet/ddd-scene-solution/xfg-dev-tech-content-moderation.git +``` + +### 3. 配置Maven + +
+ +
+ +- 在高级中设置 Maven 配置的路径 `/usr/local/maven/conf/settings.xml`。这样才能走自己配置的阿里云镜像仓库。 + +```shell +clean install -Dmaven.test.skip=true +``` + +### 3. 配置Shell + +```shell +# 先删除之前的容器和镜像文件 +if [ "$(docker ps -a | grep xfg-dev-tech-app)" ]; then +docker stop xfg-dev-tech-app +docker rm xfg-dev-tech-app +fi +if [ "$(docker images -q xfg-dev-tech-app)" ]; then +docker rmi xfg-dev-tech-app +fi + +# 重新生成 +cd /var/jenkins_home/workspace/xfg-dev-tech-jenkins/xfg-dev-tech-app +docker build -t xiaofuge/xfg-dev-tech-app . +docker run -itd -p 8091:8091 --name xfg-dev-tech-app xiaofuge/xfg-dev-tech-app +``` + +
+ +
+ +- 当你熟悉后还可以活学活用，比如这里只是做build 但不做run执行操作。具体的部署可以通过 docker compose 执行部署脚本。 +- 另外如果你有发布镜像的诉求，也可以在这里操作。 + +## 四、测试验证 + +### 1. 工程准备 + +**工程**：`https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-jenkins` 你可以fork到自己的仓库进行使用，你的账号密码就是 CSDN 的账号密码。 + +```java +@SpringBootApplication +@RestController() +@RequestMapping("/api/") +public class Application { + + public static void main(String[] args) { + SpringApplication.run(Application.class); + } + + /** + * http://localhost:8091/api/test + */ + @RequestMapping(value = "/test", method = RequestMethod.GET) + public ResponseBodyEmitter test(HttpServletResponse response) { + response.setContentType("text/event-stream"); + response.setCharacterEncoding("UTF-8"); + response.setHeader("Cache-Control", "no-cache"); + + ResponseBodyEmitter emitter = new ResponseBodyEmitter(); + + String[] words = new String[]{"嗨，臭宝。\r\n", "恭喜💐 ", "你的", " Jenkins ", " 部", "署", "测", "试", "成", "功", "了啦🌶！"}; + new Thread(() -> { + for (String word : words) { + try { + emitter.send(word); + Thread.sleep(250); + } catch (IOException | InterruptedException e) { + throw new RuntimeException(e); + } + } + }).start(); + + return emitter; + } + +} +``` + +- 工程中提供了接口；`http://localhost:8091/api/test` + +### 2.

+ +
+ +进入到 apache-jmeter-5.5/bin 目录下； + +- Mac 电脑，在 jmeter 上右键，选择终端启动。 +- Windows 电脑，直接点 jmeter.bat 启动。 + +### 2. 配置语言 + +
+ +
+ +修改语言有2个方式； + +- 进入 apache-jmeter-5.5/bin/jmeter.properties 设置 language=zh_CN +- 如图，进入页面，手动选择。 + +## 二、配置说明 + +
+ +
+ +这是 JMeter 压测配置中非常简单的一个**测试计划**，在这个测试计划下需要包括`线程组 - 负责运行`、`取样器(压测的接口) - 负责调接口`和`至少一个监听器 - 负责看结果`。这样才能完成压测并获得结果。 + +### 1. 线程组 + +
+ +
+ +通过线程组开启对HTTP接口的请求循环操作方式。它可以模拟配置出流量的负载均值请求、峰值请求、逐步加量等场景。 + +#### 1.1 函数线程组 + +
+ +
+ +- Open Mode Thread Group 支持配置简单的配置和 Groovy 脚本 如；`${__groovy((1..5).collect { "rate(" + it*10 + "/sec) random_arrivals(10 sec) pause(1 sec)" }.join(" "))}` - 请求10次，每次都递进。 +- 你还可以配置这些参数；`rate(0/min) random_arrivals(10 min) rate(100/min)`、`rate(0/min) random_arrivals(5 min) rate(100/min)random_arrivals(100 min)rate(100/min) random_arrivals(5 min) rate(0/min)` - 通过这样的规律，就可以找到如何配置了。 +- 此外还支持 JMeter 函数：`pause(2 min) rate(${__Random(10,50,)}/min)random_arrivals(${__Random(10,100,)} min) rate(${__Random(10,1000,)}/min)` - 也可以多行配置。 +- 负载举例；总时长为1分10秒。前10秒内，速率达到10/s，然后，在1分钟内吞吐量将保持在10/s。最大吞吐量为600个/分钟。配置：`rate(0/s) random_arrivals(20 s) rate(10/s) random_arrivals(1 m) rate(10/s)` + +#### 1.2 简单线程组 + +
+ +
+ +简单线程组配置起来更简单，也适合一些循环压测的场景。 +- 线程数：一个用户相当于一个线程。 +- Ramp-Up：预期线程组的所有线程从启动-运行-释放的总时间。ramp up=0时，表示瞬时加压，启动线程的时间无限趋近于0。在负载测试的时候，尽量把ramp up设置大一些，让性能曲线平缓，容易找到瓶颈点。 +- 循环次数：线程组的循环次数，如果不设置，则表示在调度时间范围内一直循环(jmeter不停的发请求)。 +- 调度器：执行的时间设置。 + +--- + +此外，JMeter 还可以安装插件，设置更多的线程组模型来压测。 + +### 2. 取样器 + +JMeter 把对压测的内容，抽象为取样器。包括HTTP接口、FTP服务等。 + +
+ +
+ +如图你可以通过这样的方式，在创建好的线程组下，创建一个取样器(HTTP压测接口)。不过这里小傅哥更建议你使用 cURL 方式导入使用。 + +#### 2.1 复制 cURL + +
+ +
+ +#### 2.2 导入 cURL + +
+ +
+ +- 导入以后，可以把HTTP请求拖到线程组下面。 + +### 3. 监听器 + +线程组是各类方式的模拟压测调用，取样器HTTP是压测的接口。那么监听器就是看线程组对取样器HTTP的压测结果。 + +
+ +
+ +## 三、工程准备 + +为了让大家更加方便的测试，不用自己在折腾，可以直接使用测试工程。测试工程内提供了测试的接口，以及对应的 jmx 脚本。启动后就可以执行测试。 + +
+ +
+ +- docker-compose.yml 是部署 JMeter 到 Docker 的脚本。并在脚本中映射了本地的压测脚本。 +- one.jmx 是在使用 JMeter 时导出的脚本，你可以直接复制 JMeter 脚本，也可以让 JMeter 保存脚本的时候选择到这个路径下。 +- 注意 one.jmx 有压测对应接口的 IP，测试的时候需要修改为你的服务器/本机IP才可以。`127.0.0.1` + +## 四、压测验证 + +### 1. 本地压测 + +- 开启服务：xfg-dev-tech-jmeter +- 启动压测：JMeter + +
+ +
+ +
+ +
+ +### 2. 脚本压测 + +
+ +
+ +压测命令：`jmeter -n -t one.jmx -l one.jtl` + +## 五、其他工具 + +- [ApacheBench](https://httpd.apache.org/docs/2.4/programs/ab.html)：一个轻量级的HTTP性能测试工具，可以模拟多种类型的负载，并提供详细的测试报告。脚本：`ab -n 10 -c 2 http://localhost:8091/api/jmeter/query_order_info?orderId=100001` +- [Siege](#)：是常用的HTTP性能测试工具，可以模拟多个并发用户发送请求。脚本：`siege -c10 -r1 -p http://localhost:8091/api/jmeter/query_order_info?orderId=100001` +- [ApiPost](https://www.apipost.cn/)：自带接口简单压测模拟，安装更加简单，适合初步压测验证。 \ No newline at end of file diff --git a/docs/md/road-map/joycode.md b/docs/md/road-map/joycode.md new file mode 100644 index 000000000..4bdf9bb1f --- /dev/null +++ b/docs/md/road-map/joycode.md @@ -0,0 +1,209 @@ +--- +title: JoyCode +lock: need +--- + +# JoyCode - 代码洪流 一念即成！ + +作者：小傅哥 +

+ +- 你可以通过 Create 创建主题消息，填写后点击 Submit 保存。 + +## 二、消息流程 + +本节的重点内容在于如何优雅的发送 MQ 消息，让消息聚合到领域层中，并在发送的时候可以不需要让使用方关注过多的细节。【如图】 + +
+ +
+ +- 在领域层中提供一个 event 包，定义事件消息。也就是一个领域中要发什么消息，就定义什么消息。这个消息只归属于当前领域中。 +- 定义的消息则由仓储继承实现【一个领域如果拆分的合理，一般只会有一 +- 个事件驱动，也就有一个事件消息】，如果是有多个消息一种是拆分领域，另外一种是提供多个仓储，还有一种是由仓储层注入实现。 +- 这里我们先有个影响，之后在到代码部分再看下就会更加清楚是怎么实现的了。 + +## 三、代码实现 + +### 1. 工程结构 + +
+ +
+ +- domain 是领域层，提供一个个领域服务。如果一个工程有多个领域，则有不同的 a、b、c 领域包，每个包下有一套【event、model、repository、service】。 +- 在领域层定义的 event 事件，里面涵盖了事件消息。而这个事件消息可以让 UserRepository 继承实现。最终完成消息发送。 +- 最后是 trigger 触发器层，所有的 http、rpc、job、mq 都是一种触发行为。通过触发器的 listener 监听，来接收 mq 消息。 + +### 2. 环境配置 + +application-dev.yml + +```yml +spring: + kafka: + bootstrap-servers: localhost:9092 + producer: + # 发生错误后，消息重发的次数。 + retries: 1 + #当有多个消息需要被发送到同一个分区时，生产者会把它们放在同一个批次里。该参数指定了一个批次可以使用的内存大小，按照字节数计算。 + batch-size: 16384 + # 设置生产者内存缓冲区的大小。 + buffer-memory: 33554432 + # 键的序列化方式 + key-serializer: org.apache.kafka.common.serialization.StringSerializer + # 值的序列化方式 + value-serializer: org.apache.kafka.common.serialization.StringSerializer + # acks=0 ： 生产者在成功写入消息之前不会等待任何来自服务器的响应。 + # acks=1 ： 只要集群的首领节点收到消息，生产者就会收到一个来自服务器成功响应。 + # acks=all ：只有当所有参与复制的节点全部收到消息时，生产者才会收到一个来自服务器的成功响应。 + acks: 1 + +... + +# 配置主题 +kafka: + topic: + group: xfg-group + user: xfg-topic +``` + +- 完整配置可参考源码。 +- 需要注意的配置，`bootstrap-servers: localhost:9092` +- user: xfg-topic 是发送消息的主题，可以在 kafka 后台创建。 +- group: xfg-group 任意即可。 + +### 2. 代码实现 + +#### 2.1 配置发送事件 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.event.EventPublisher` + +```java +@Slf4j +@Component +public class EventPublisher { + + @Resource + private KafkaTemplate kafkaTemplate; + + public void publish(String topic, BaseEvent.EventMessage eventMessage) { + try { + String messageJson = JSON.toJSONString(eventMessage); + kafkaTemplate.send(topic, messageJson); + log.info("发送MQ消息 topic:{} message:{}", topic, messageJson); + } catch (Exception e) { + log.error("发送MQ消息失败 topic:{} message:{}", topic, JSON.toJSONString(eventMessage), e); + throw e; + } + } + +} +``` + +- 这个是一个启动 kafka 消息的模板。我们把它放到基础层中。 + +#### 2.2 事件消息定义 + +**源码**：`cn.bugstack.xfg.dev.tech.domain.event.UserMessageEvent` + +```java +public class UserMessageEvent extends BaseEvent { + + @Value("${kafka.topic.user}") + private String topic; + + @Override + public EventMessage buildEventMessage(UserMessage data) { + return EventMessage.builder() + .id(RandomStringUtils.randomNumeric(11)) + .timestamp(new Date()) + .data(data) + .build(); + } + + @Override + public String topic() { + return topic; + } + + /** + * 要推送的事件消息，聚合到当前类下。 + */ + @Data + @Builder + @AllArgsConstructor + @NoArgsConstructor + public static class UserMessage { + private String userId; + private String userName; + private String userType; + } + +} +``` + +- 首先，BaseEvent 是一个基类，定义了消息中必须的 id、时间、泛型数据。每一个要发送的消息都按照这个结构来发。 +- 关于消息的发送，这是一个非常重要的设计手段，事件消息的发送，消息体的定义，聚合到一个类中来实现。可以让代码更加整洁。 + +#### 2.3 事件消息发送 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.repository.UserRepository` + +```java +@Service +public class UserRepository extends UserMessageEvent implements IUserRepository { + + @Resource + private EventPublisher publisher; + + @Override + public void doSaveUser(UserEntity userEntity) { + // 推送消息 + publisher.publish(this.topic(), this.buildEventMessage(UserMessageEvent.UserMessage.builder() + .userId(userEntity.getUserId()) + .userName(userEntity.getUserName()) + .userType(userEntity.getUserTypeVO().getDesc()) + .build())); + } + +} +``` + +- 用仓储实现类继承事件消息，在完成数据的操作后，推送消息。 + +#### 2.4 事件消息监听 + +**源码**：`cn.bugstack.xfg.dev.tech.trigger.listener.KafkaMessageListener` + +```java +@Slf4j +@Component +public class KafkaMessageListener { + + @KafkaListener(topics = "${kafka.topic.user}", groupId = "${kafka.topic.group}", concurrency = "1") + public void topic_test(ConsumerRecord record, Acknowledgment ack, @Header(KafkaHeaders.RECEIVED_TOPIC) String topic) { + Optional message = Optional.ofNullable(record.value()); + if (message.isPresent()) { + Object msg = message.get(); + try { + // 逻辑处理 + + // 确认消息消费完成，如果抛异常消息会进入重试 + ack.acknowledge(); + log.info("Kafka消费成功!

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +不少程序员👨🏻‍💻伙伴，一到618、双11和开学季的时候，总会问买个 Windows 电脑，还是搞个 MacBook Pro？网上搜的很多对比，都是说同配置的苹果更贵，但心里总痒痒也好奇，MacBook Pro 是不更好用还能装个B！ + +
+ +
+ +**如果你是程序员👨🏻‍💻，我更推荐苹果电脑。为啥？** + +首先，Windows 和 Mac 没有好坏之分，只不过 Windows 有 Windows 的使用场景、Mac 有 Mac 的应用领域。你喜欢打游戏、折腾些硬件对接、综合工作和娱乐，那 Windows 就是最强的选择。 + +但如果只在程序员这一行业对比编程写代码，一台笔记本，灵敏的触控板让你忘记鼠标的存在，苹果 IOS、IPad、Mac 全家桶式的多设备互通，可以做到极致的体验。 + +而更重要的是，Java 写好的代码是要放到 Linux 运行，而不是 Windows，所有你在所需的环境、所编写的脚本，可以无差别从 Mac 转移到 Linux 使用。这是 Windows 没法做到的，甚至 Windows 要在这块浪费掉你很多的时间。*不是不能用，就是不丝滑！* + +>接下来，小傅哥分享下 Mac 电脑的使用经验。新入坑伙伴可以参考。 + +## 一、我的经历 - 入坑 Mac！ + +2019年，在这之前我只用过 Windows 电脑，包括；台式机、笔记本，还有自己DIY的台式机。Windows 给我感觉就是抗造，能自己折腾，加个内存，换个固态硬盘。打起来游戏方便，无论是澄海3c还是lol英雄联盟。 + +但在这之前，我也就只有一台 thinkstation 的台式机，每次长假期赔媳妇出门，我都想着要是有个笔记本电脑，我就可以在外面写代码。要不多没意思。所以，我的理由就有了！ + +2019年，趁着618活动，搞了第一台 Mac 电脑 i5 8G 256G SSD。说实话这个配置一点也不高，而且价格也不便宜 `¥10189.00` 元。好在送一个 `Beats Solo3 Wireless`耳麦。 + +
+ +
+ +不过 `Beats Solo3 Wireless` 被我在咸鱼转手卖掉回血了。 + +
+ +
+**但谁能想得到，这台电脑在5个月以后，还能给我返回来 5000 元！** + +2019年，双11备战誓师大会。抽取幸运备战人员，清空购物车！最高清空额度，就是同年 618 期间消费的额度，上限 5000 元！ + +
+ +
+ +这不巧了🐴，这不巧了🐴！618，我呀，我买了电脑，` ¥10189.00`！Duang、Duang、Duang，大转盘一转，还真抽中我了！那一刻，我决定做个抽奖系统！ + +
+ +
+ +从此开启了苹果全家桶系列，苹果手机、IPad mini、IPad Pro ...，讲真，确实好用！那有人问，你 Mac 电脑，也打不了游戏呀？嗯，我媳妇给我买了PS5，还中了一台 Switch 😂 + +> 是的，后来我做了 Lottery 抽奖系统，还有大营销系统（Lottery Plus）！ + +## 二、体验对比 - Mac 优势 + +这里我不谈那些打游戏、或者和一些硬件的适配。因为你有那些诉求，直接选择 Windows 就可以。比如；外星人也不错。 + +- 续航基本在10个小时左右，你是不需要带着充电电源的。像是在公司，双周需求评审，要占用一整个下午，这个期间电脑不需要插电源。 +- 不需要每天早上来开机，晚上回去关机。只要它不死机，甚至半年不都不关机。合上就走，打开就用。 +- 对于常用的技术编程环境类软件，直接下载就安装。因为这类软件是按照 Linux 系统做的，不是按照 Windows 系统做的。很多时候 Windows 要做兼容。比如执行脚本、安装 Docker，Windows 都要折腾一下。 +- 不需要安装各类杀毒软件，安装和卸载软件十分方便。有一些 Mac 的软件是付费的软件，但很多是一次付费终身使用，一点广告没有。不付费也可以破解使用，很多 Mac 软件都提供了破解版。 +- 尤其是 M2、M3 系列的 Mac，性能很炸裂，同时开几个 IDEA + 一堆环境类软件，以及一堆的打开的网页也很丝滑。 +- 切屏极其容易，多屏幕工作在 Mac 上是利器，可以不同的屏幕处理不同的事项。但在 Windows 切屏就挺费力气！ +- Mac 电脑可以外接显示器，这个 Windows 也有。但 Mac 还可以和 IPad 联动，功能叫随行。 +- Mac 上复制的内容，或者苹果手机上复制内容，可以互相粘贴。也可以极其简单的方式互传文件。 +- Mac 电脑的触控板，一周内可习惯，习惯后不需要使用鼠标了。感受过 Mac 的触控板，会感觉鼠标是个鸡肋。间接的你不会有一个鼠标手「长时间用鼠标会做病」。 +- 和其他的软件设备，比如 nas 可以直接链接操作。你可以 Mac 电脑打开 idea，但代码放到 nas 上。这个很爽！并且 nas 可以直接给你提供 docker 环境。下一期可以介绍下 nas 的使用。 + +>其实，我认为还有一点是最重要的。做软件开发的，应该体验最好的软件逻辑。这可以让你的编程思维得到提升。虽然 Mac 比 Windows 贵，但折腾 Windows 浪费的时间也很贵。 + +## 三、装机分享 - 我的软件 + +Mac 电脑的软件非常好安装，双击打卡，之后交给它！ + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +诶，`你八股背的挺好，怎么实操这么差？`哎，`你算法刷的挺多，怎么编码这么烂？`啊，`你不是做过微服务，怎么不知道咋引包？`这是越来越多的面试官在招聘完的真实反馈，很多伙伴的经验不是来自于实践而是背诵！ + +

+ +
+ +对于这样的报错，我估计不少伙伴碰到了都有点慌。怎么我刚下载下来的工程，什么都做没做就报错了。这个包在仓库里也没有呀？之所以你会感觉很慌，是因为没有微服务项目的开发经验。 + +
+ +
+只要你碰到这样一个报错，那么在“作者/开发者/公司”的仓库中，一定会有这样一个其他的微服务，只要下载到自己本地，用 IntelliJ IDEA 打开，点击右侧的 maven install 就可以初始化包到你的本地 Maven 仓库了，这样你就能引入了。 + +那关于微服务的包的构建和使用有什么管理和规范吗？🤔 有的！ + +## 二、微服务包管理 + +无论是我们个人开发还是在公司开发，都是有一套微服务包的开发和推送以及使用的规范。大家默认统一遵守，所以开发中才会非常协调的进行。 + +
+ +
+ +首先，公司中有很多业务，很多需求，这些东西不能都在一个工程里开发。那么势必就会拆分为多个微服务系统以及通用的技术解决方案组件。那么这些微服务和组件之间就会存在引入调用关系。尤其是一些大的互联网公司，更是会采用 RPC 的通信解决内部微服务之间的高效调用，而 RPC 通信不同于 HTTP 是需要引入接口定义包的，所以必然存在一个微服务中引入另外一个微服务的 Jar 也就是 POM 配置。 + +那么，如果是你个人验证阶段，是先在自己本地开发验证。这个时候不会发包到 maven 公司统一仓库或者中心仓库，那么就需要你自己本地在 A 服务中进行 install，把包发到个人的 maven 本地仓库文件夹中，之后你的 B 服务就可以引入使用了。 + +之后，站在整个公司的视角。你开发完的组件，不只是你使用，还有其他很多人使用。但跨部门，跨组的别人又不一定都有你的代码库权限，这个时候就需要把本地微服务的 Jar 发包到公司的 Maven 镜像库中。一般稍微大一点的公司都会有自己的 Maven 镜像库，如果公司比较小则会使用阿里云这类云厂商提供的的制品库，如；[https://packages.aliyun.com/](https://packages.aliyun.com/) 让公司的所有人 Maven setting 配置文件都配置这套制品库，这样就解决了一个人发包，其他人也能拉取到使用。 + +另外，如果你想你发的包，不只是你自己或公司里的人使用，那么就要把包发到 Maven 统一的中心仓库。[https://central.sonatype.com/publishing](https://central.sonatype.com/publishing) 这个过程稍微有点漫长，会持续 `4-12` 个小时才能完全同步好。 + +> 下文会提到如何发包到阿里云制品库和 Maven 中心仓库。 + +## 三、微服发包规范 + +工程发包会分为开发阶段的 snapshot 包和正式上线使用的 release 包，snapshot 包同一个版本发包后可以被替代，release 包，只能每次更换版本号。 + +```pom + + cn.bugstack + xfg-dev-tech-api + 0.0.0-SNAPSHOT + + + + cn.bugstack + xfg-dev-tech-api + 1.0 + +``` + +- 0.0.0-SNAPSHOT 以 SNAPSHOT 结尾是开发阶段包，都是 0.0.0-SNAPSHOT 命名。 +- release 包，只需要命名版本号即可。 + +另外这样的微服务包的版本号，在一个工程中每个模块都需要在发包的时候一起操作修改。如果是手动的修改就容易遗漏导致问题，所以这里我们要使用 Maven 提供的插件管理包。如； + +``` + + org.codehaus.mojo + versions-maven-plugin + 2.7 + +``` + +
+ +
+ +- 配置好 `versions-maven-plugin` 点击 `version:set` 就可以统一管理工程的版本号了。 + +## 四、阿里云效发包 - 研发组内用 + +### 1. 阿里云制品库 + +地址：[https://packages.aliyun.com/](https://packages.aliyun.com/) - 填写个人信息申请即可。 + +
+ +
+ +申请后，你会看到制品仓库配置，包括生产库和非生产库，他们主要负责给你提供 release、snapshot 发包和拉取。 + +### 2. 发包配置 + +分别进入 release、snapshot，都可以获得一份 Maven settings.xml 配置文件，把两份文件夹下载后可以找到 release、snapshot 的差异，合并成一份文件。这样你就可以在本地发 release、snapshot 包了。 + +

+ +

+ +
+ +**打开工程时：** + +
+ +
+ +- 配置好你的 Maven 地址就可以使用了。 + +## 四、命令操作 + +IntelliJ IDEA Maven 面板提供了操作控制； + +
+ +
+ +- clean：清理，执行该命令会删除项目路径下的target文件，但是不会删除本地的maven仓库已经生成的jar文件。 +- validate：验证，验证工程正确性，所需信息完整否。 +- compile：编译，大伙都知道java的识别文件是.class，编译生成class文件,编译命令，只编译选定的目标，不管之前是否已经编译过，会在你的项目路径下生成一个target目录，在该目录中包含一个classes文件夹，里面全是生成的class文件及字节码文件。与build区别：只编译选定的目标，不管之前是否已经编译过。 +- test：测试，单元测试。 +- package：打包，将工程文件打包为指定的格式，例如JAR，WAR等（看你项目的pom文件，里面的packaging标签就是来指定打包类型的）。这个命令会在你的项目路径下一个target目录，并且拥有compile命令的功能进行编译，同时会在target目录下生成项目的jar/war文件。如果a项目依赖于b项目，打包b项目时，只会打包到b项目下target下，编译a项目时就会报错，因为找不到所依赖的b项目，说明a项目在本地仓库是没有找到它所依赖的b项目，这时就用到install命令。 +- verify：核实，主要是对package检查是否有效、符合标准。 +- install：安装，将包安装至本地仓库，以让其它项目依赖。该命令包含了package命令功能，不但会在项目路径下生成class文件和jar包，同时会在你的本地maven仓库生成jar文件，供其他项目使用（如果没有设置过maven本地仓库，一般在用户/.m2目录下。如果a项目依赖于b项目，那么install b项目时，会在本地仓库同时生成pom文件和jar文件，解决了上面打包package出错的问题）。 +- build：建造，功能类似compile，区别是对整个项目进行编译。与compile区别及特点：是对整个工程进行彻底的重新编译，而不管是否已经编译过。Build过程往往会生成发布包，这个具体要看对IDE的配置了，Build在实际中应用很少，因为开发时候基本上不用，发布生产时候一般都用ANT等工具来发布。Build因为要全部编译，还要执行打包等额外工 作，因此时间较长。 +- site：站点，生成项目的站点文档。 +- deploy：配置部署，复制到远程仓库。前提需要在工程 POM 和 Maven 里配置上相关的信息以及账号。 + +## 五、构建配置 + +```java + + 项目名称 + + + org.apache.maven.plugins + maven-compiler-plugin + 3.0 + + 1.8 + 1.8 + UTF-8 + + + + org.apache.maven.plugins + maven-resources-plugin + 2.5 + + UTF-8 + + + + + org.codehaus.mojo + versions-maven-plugin + 2.7 + + + +``` + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +本文的宗旨在于通过简单干净实践的方式教会读者，如何使用 [Mock](https://zh.wikipedia.org/wiki/%E6%A8%A1%E6%8B%9F%E5%AF%B9%E8%B1%A1) 进行工程的单元测试，以便于验证系统中的独立模块功能的健壮性。 + +从整个工程所处不同阶段的测试手段包括；单元测试、集成测试、系统测试、验收测试、性能测试、安全测试、回归测试，以及兼容、可靠、可用性测试。 + +而单元测试的重点在于，对工程开发中的代码，进行流程中的单元化测试。如一整个下单流程中，需要调用各项外部的接口(风控、账户、营销、试算、支付)，才能完成整个下单流程。但在本地开发过程中，不太能将所有的外部接口都调试为开发环境可用状态，所有这个时候要做单元化测试，对于一些不能随时提供服务的接口进行 [Mock](https://zh.wikipedia.org/wiki/%E6%A8%A1%E6%8B%9F%E5%AF%B9%E8%B1%A1) 处理。 + +本文涉及的工程： + +- xfg-dev-tech-mock：[https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-mock](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-mock) +- chatglm-sdk-java：[https://gitcode.net/KnowledgePlanet/road-map/chatglm-sdk-java](https://gitcode.net/KnowledgePlanet/road-map/chatglm-sdk-java) + +## 一、案例背景 + +因为 Mock 单元测试的重点，主要体现在；功能流程较长、调用外部接口稳定性较差、测试过程中希望可以不启动 SpringBoot 应用就能对单个功能模块进行测试验证。 + +所以本章节带着这样一个案例背景的情况，小傅哥带着大家把 [《HTTP 框架使用和场景实战 - 结合ChatGLM自动回帖！》](https://bugstack.cn/md/road-map/http.html) 做一个小重构。来对 Mock 框架进行验证使用。 + +
+ +
+ +- 首先，这里使用 DDD 工程模型结构，搭建出测试工程。—— DDD 是一种软件设计方法，而软件的设计方法涵盖了；范式、模型、框架、方法论。所以通常下 MVC 与 DDD 的对比先从模型、框架在到思想设计和方法论。 +- 之后，我们在这样的一个模型结构下，实现出自动回帖的领域功能。而这个模型的实现恰好需要调用外部的接口和 ChatGLM SDK，这与我们要做的 Mock 测试正好符合，因为在大部分开发场景下，远程的 HTTP 调用可能不不会一直可用，所以可以用 Mock 方式进行模拟。 + +## 二、功能实现 + +### 1. 工程结构 + +
+ +
+ +- 在 domain 中实现一个zsxq的自动回帖领域，而它所需的要调用的接口则由基础设施层提供。 +- 另外在 app 中还有 ChatGLM SDK 的配置启动，也会被注入到 AiReply 实现类中。 + +### 2. Ai模块启动 + +```yml +# ChatGLM SDK Config +chatglm: + sdk: + config: + # 状态；true = 开启、false 关闭 + enabled: false + # 官网地址 + api-host: https://open.bigmodel.cn/ + # 官网申请 https://open.bigmodel.cn/usercenter/apikeys + api-secret-key: d570f7c5d289cdac2abdfdc562e39f3f.trqz1dH8ZK6ED7Pg +``` + +```java +@Bean +@ConditionalOnProperty(value = "chatglm.sdk.config.enabled", havingValue = "true", matchIfMissing = false) +public OpenAiSession openAiSession(ChatGLMSDKConfigProperties properties) { + // 1. 配置文件 + cn.bugstack.chatglm.session.Configuration configuration = new cn.bugstack.chatglm.session.Configuration(); + configuration.setApiHost(properties.getApiHost()); + configuration.setApiSecretKey(properties.getApiSecretKey()); + // 2. 会话工厂 + OpenAiSessionFactory factory = new DefaultOpenAiSessionFactory(configuration); + // 3. 开启会话 + return factory.openSession(); +} +``` + +- 所有的这些配置类的服务，都可以放到 app下的 config 模块中。 +- ChatGLM 可以直接在官网申请，默认会赠送18元的额度，对于它所提供的模型，还是非常够测试使用的。 + +### 3. 基础设置 - 接口调用 + +#### 3.1 接口 - 防腐对接 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.gateway.api.IZSXQApi` + +```java +public interface IZSXQApi { + + /** + * 查询知识星球帖子内容 + * + * @return 帖子数据 + * @throws IOException 异常 + */ + ResponseDTO topics() throws IOException; + + /** + * 回复帖子 + * + * @param topicId 帖子ID + * @param content 回复内容 + */ + void comment(long topicId, String content); + +} +``` + +- 在基础设置层中定义 gateway 网关接口调用，对于外部的接口使用，中间要做一层防腐，不要直接把外部的接口暴露出去使用。 + +#### 3.2 使用 - 依赖倒置 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.gateway.adapter.ZSXQAdapter` + +```java +public class ZSXQAdapter implements IZSXQAdapter { + + @Resource + private IZSXQApi zsxqApi; + + @Override + public List queryTopics() { + try { + ResponseDTO responseDTO = zsxqApi.topics(); + RespData respData = responseDTO.getRespData(); + List topics = respData.getTopics(); + List topicsItemVOList = new ArrayList<>(); + + for (TopicsItem topicsItem : topics) { + TopicsItemVO topicsItemVO = TopicsItemVO.builder() + .topicId(topicsItem.getTopicId()) + .talk(topicsItem.getTalk().getText()) + .showCommentsItems(topicsItem.getShowComments() != null ? topicsItem.getShowComments().stream() + .map(showCommentsItem -> { + TopicsItemVO.ShowCommentsItem item = new TopicsItemVO.ShowCommentsItem(); + item.setUserId(showCommentsItem.getOwner().getUserId()); + return item; + }) + .collect(Collectors.toList()) : new ArrayList<>()) + .build(); + + topicsItemVOList.add(topicsItemVO); + } + + return topicsItemVOList; + } catch (IOException e) { + throw new RuntimeException(e); + } + } + + @Override + public boolean comment(long topicId, String content) { + zsxqApi.comment(topicId, content); + return true; + } + +} +``` + +- 注意，TopicsItemVO 对象来自于 domain 下领域中模型下的 VO 对象。因为是依赖倒置的，所以 infrastructure 引用的是 domain 并对其接口做实现处理。 +- 并且，TopicsItemVO 只是需要获取自己需要的对象，还可以做简单的封装处理。这样可以衔接外部接口和内部逻辑中间的桥梁，不做强关联。 + +### 4. 任务调度 + +**源码**：`cn.bugstack.xfg.dev.tech.job.ReplyJob` + +```java +public class ReplyJob { + + @Resource + private IAiReply aiReply; + + @Scheduled(cron = "0/10 * * * * ?") + public void exec() throws Exception { + log.info("自动回帖任务开始执行..."); + aiReply.doAiReply(); + } + +} +``` + +- 现在在 trigger 触发器层中的 job 下，就可以调用我们已经实现好的 AiReply 自动回帖功能了。 +- 此外，注意 Application 中 `@EnableScheduling` 注解是开启的，否则任务不能执行。 + +## 三、系统测试 + +### 1. 集成测试 + +```java +@Slf4j +@RunWith(SpringRunner.class) +@SpringBootTest +public class ApiTest { + + @Resource + private IAiReply aiReply; + + @Test + public void test_IAiReply() { + aiReply.doAiReply(); + } + +} +``` + +- 通常情况下这种测试是最多的，写多少功能，就直接测试调用。如功能中所用到的；HTTP接口、RPC接口、数据库、Redis等资源，都会需要使用到。有时候也因为这样，所以不好测试。那么单元测试就出现了。 + +### 2. 单元测试 + +```java +@Slf4j +@RunWith(SpringRunner.class) +@SpringBootTest +public class MockTest { + + @Resource + private IAiReply aiReply; + + @MockBean + private IZSXQAdapter izsxqAdapter; + + @Test + public void test_doAiReply() throws InterruptedException, JsonProcessingException { + Mockito.when(izsxqAdapter.queryTopics()).thenReturn(new ArrayList() {{ + TopicsItemVO topicsItemVO = new TopicsItemVO(); + topicsItemVO.setTopicId(10001L); + topicsItemVO.setTalk(" 提问 java 冒泡排序"); + add(topicsItemVO); + }}); + + Mockito.when(izsxqAdapter.comment(Mockito.anyLong(), Mockito.anyString())).thenReturn(true); + + aiReply.doAiReply(); + + // 等待；ChatGLM 异步回复 + new CountDownLatch(1).await(); + } + +} +``` + +
+ +
+ +- 在基于使用 SpringBoot 的启动，以及一部分功能需要走真实调用的情况下，另外一部分功能的接口可能没法调用时。可以使用这样的一种 MockBean 的方式进行处理，并对整条链路上调用到的接口方法进行 Mock 处理。`Mockito.when(调用到的接口).thenReturn(返回的结果); +- 那么现在在测试方法中，做了2个Mock操作，把查询帖子和回复帖子，都给处理掉。也就是有了 Mock 以后，程序调用到这里，就直接走 Mock 里设置的结果信息了。 + +### 3. 功能测试 + +```java +@Slf4j +@RunWith(MockitoJUnitRunner.class) +public class ZSXQAdapterTest { + + @Mock + private IZSXQApi mockZsxqApi; + + @InjectMocks + private ZSXQAdapter zsxqAdapterUnderTest; + + @Test + public void testQueryTopics() throws Exception { + // Setup + final List expectedResult = Arrays.asList(TopicsItemVO.builder() + .topicId(0L) + .talk("talk") + .showCommentsItems(Arrays.asList(TopicsItemVO.ShowCommentsItem.builder() + .userId(0L) + .build())) + .build()); + + // Configure IZSXQApi.topics(...). + final ResponseDTO responseDTO = new ResponseDTO(); + final RespData respData = new RespData(); + final TopicsItem topicsItem = new TopicsItem(); + final ShowCommentsItem showCommentsItem = new ShowCommentsItem(); + final Owner owner = new Owner(); + owner.setUserId(0L); + showCommentsItem.setOwner(owner); + topicsItem.setShowComments(Arrays.asList(showCommentsItem)); + final Talk talk = new Talk(); + talk.setText("talk"); + topicsItem.setTalk(talk); + topicsItem.setTopicId(0L); + respData.setTopics(Arrays.asList(topicsItem)); + responseDTO.setRespData(respData); + when(mockZsxqApi.topics()).thenReturn(responseDTO); + + // Run the test + final List result = zsxqAdapterUnderTest.queryTopics(); + + // Verify the results + assertEquals(expectedResult, result); + + log.info("测试结果：{}", JSON.toJSONString(result)); + } + +} +``` + +
+ +
+ +- 除了前面两种测试，我们在开发功能的时候，还有场景测试；不启动 SpringBoot 但希望对实现的功能进行测试。 +- 那么这里所体现的就是这样的测试，主要使用；`@RunWith(MockitoJUnitRunner.class)`、`@Mock`、`@InjectMocks` 相当于模拟了一个启动的过程，只不过都是 Mock 的信息。但你可以根据这些信息来调试你的接口。 +- 提示：你可以安装 `IDEA Plugin Squaretest` 它能自动的帮你生成Mock单元测试。`这个插件是收费的，但还好不贵。` diff --git a/docs/md/road-map/mvc.md b/docs/md/road-map/mvc.md new file mode 100644 index 000000000..8f3d6027e --- /dev/null +++ b/docs/md/road-map/mvc.md @@ -0,0 +1,140 @@ +--- +title: MVC 架构设计 +lock: need +--- + +# 架构的本质之 MVC 架构 + +作者：小傅哥 +

+ +所以，为了不至于让一个类撑到爆💥，需要把黄色的对象、绿色的方法、红色的接口，都分配到不同的包结构下。这就是你编码人生中所接触到的第一个解耦操作。 + +## 二、分层框架 + +MVC 是一种非常常见且常用的分层架构，主要包括；M - mode 对象层，封装到 domain 里。V - view 展示层，但因为目前都是前后端分离的项目，几乎不会在后端项目里写 JSP 文件了。C - Controller 控制层，对外提供接口实现类。DAO 算是单独拿出来用户处理数据库操作的层。 + +
+ +
+ +- 如图，在 MVC 的分层架构下。我们编程3步的所需各类对象、方法、接口，都分配到 MVC 的各个层次中去。 +- 因为这样分层以后，就可以很清晰明了的知道各个层都在做什么内容，也更加方便后续的维护和迭代。 +- 对于一个真正的项目来说，是没有一锤子买卖的，最开始的开发远不是成本所在。最大的开发成本是后期的维护和迭代。而架构设计的意义更多的就是在解决系统的反复的维护和迭代时，如何降低成本，这也是架构分层的意义所在。 + + +## 三、调用流程 + +接下来我们再看下一套 MVC 架构中各个模块在调用时的串联关系； + +
+ +
+ +- 以用户发起 HTTP 请求开始，Controller 在接收到请求后，调用由 Spring 注入到类里的 Service 方法，进入 Service 方法后有些逻辑会走数据库，有些逻辑是直接内部自己处理后就直接返回给 Controller 了。最后由 Controller 封装结果返回给 HTTP 响应。 +- 同时我们也可以看到各个对象在这些请求间的一个作用，如；请求对象、库表对象、返回对象。 + +## 四、架构源码 + +### 1. 环境 + +- JDK 1.8 +- Maven 3.8.6 - 下载安装maven后，本地记得配置阿里云镜像，方便快速拉取jar包。源码中 `docs/maven/settings.xml` 有阿里云镜像地址。 +- SpringBoot 2.7.2 +- MySQL 5.7 - 如果你使用 8.0 记得更改 pom.xml 中的 mysql 引用 + +### 2. 架构 + +- **源码**：[`https://gitcode.net/KnowledgePlanet/road-map/xfg-frame-mvc`](https://gitcode.net/KnowledgePlanet/road-map/xfg-frame-mvc) +- **树形**：`安装 brew install tree` `IntelliJ IDEA Terminal 使用 tree` + +```java +. +├── docs +│   └── mvc.drawio - 架构文档 +├── pom.xml +├── src +│   ├── main +│   │   ├── java +│   │   │   └── cn +│   │   │   └── bugstack +│   │   │   └── xfg +│   │   │   └── frame +│   │   │   ├── Application.java +│   │   │   ├── common +│   │   │   │   ├── Constants.java +│   │   │   │   └── Result.java +│   │   │   ├── controller +│   │   │   │   └── UserController.java +│   │   │   ├── dao +│   │   │   │   └── IUserDao.java +│   │   │   ├── domain +│   │   │   │   ├── po +│   │   │   │   │   └── User.java +│   │   │   │   ├── req +│   │   │   │   │   └── UserReq.java +│   │   │   │   ├── res +│   │   │   │   │   └── UserRes.java +│   │   │   │   └── vo +│   │   │   │   └── UserInfo.java +│   │   │   └── service +│   │   │   ├── IUserService.java +│   │   │   └── impl +│   │   │   └── UserServiceImpl.java +│   │   └── resources +│   │   ├── application.yml +│   │   └── mybatis +│   │   ├── config +│   │   │   └── mybatis-config.xml +│   │   └── mapper +│   │   └── User_Mapper.xml +│   └── test +│   └── java +│   └── cn +│   └── bugstack +│   └── xfg +│   └── frame +│   └── test +│   └── ApiTest.java +└── road-map.sql +``` + +以上是整个🏭工程架构的 tree 树形图。整个工程由 SpringBoot 驱动。 +- Application.java 是启动程序的 SpringBoot 应用 +- common 是额外添加的一个层，用于定义通用的类 +- controller 控制层，提供接口实现。 +- dao 数据库操作层 +- domain 对象定义层 +- service 服务实现层 + +## 五、测试验证 + +- 首先；整个工程由 SpringBoot 驱动，提供了 road-map.sql 测试 SQL 库表语句。你可以在自己的本地mysql上进行执行。它会创建库表。 +- 之后；在 application.yml 配置数据库链接信息。 +- 之后就可以打开 ApiTest 进行测试了。你可以点击 Application 类的绿色箭头启动工程，使用 UserController 类提供接口的方式调用程序；http://localhost:8089/queryUserInfo + +

项目：[大营销平台系统](https://bugstack.cn/md/project/big-market/ddd.html) - DDD 领域驱动设计，战略、战术、战役，落地指引规范。 + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主小傅哥。**MVC讲解了，DDD讲解了。接下来这个章节，我们讲讲从MVC到DDD的重构！** + +为了避免概念的混淆和下文内容方便讲解，先进行DDD概念认知确认： + +1. [Domain-driven design (DDD) is a major software design approach.](https://en.wikipedia.org/wiki/Domain-driven_design) 来自维基百科。DDD 是一种软件设计方法。 +2. 软件的设计方法涵盖了：范式、模型、框架、方法论，主要活动包括建模、测试、工程、开发、部署、维护。来自维基百科的[软件设计](https://en.wikipedia.org/wiki/Software_design)涵盖信息介绍。 +3. 所以在当前语境下，MVC与DDD的对比，只是对比软件落地的框架结构，并不是软件设计思想和思维建模的全方面对比。所以如果读者再给一些其他伙伴阐述MVC和DDD的对比时，也是有必要说明语境的，避免没必要的纠结于理论，而忽略了交流讨论的意义。 + +那么，接下来在此语境下，我们进行MVC和DDD的重构讲解： + +**MVC 旧工程腐化严重，迭代成本太高。DDD 新工程全部重构，步子扯的太大。** 这是现阶段在工程体系化治理中，我们所面临的最大问题：`既想运用 DDD 的思想循序渐进重构现有工程，又想不破坏原有的工程体系结构以保持新需求的承接效率。` + +
+ +
+ +经过实践得知，DDD 架构能解决，现阶段 MVC 贫血结构中所遇到的众多问题。 + +众所周知，MVC 分层结构是一种贫血模型设计，它将”状态“和”行为“分离到不同的包结构中进行开发使用。domain 里写 po、vo、enum 对象，service 里写功能逻辑实现。也正因为 MVC 结构没有太多的约束，让前期的交付速度非常快。但随着系统工程的长期迭代，贫血对象开始被众多 serivice 交叉使用，而 service 服务也是相互调用。这样缺少一个上下文关系的开发方式，让长期迭代的 MVC 工程逐步腐化到严重腐化。 + +**MVC 工程的腐化根本**，就在于对象、服务、组件的交叉混乱使用。时间越长，腐化的越严重。 + +
+ +
+ +在 MVC 的分层结构就像家里所有人的衣服放一个大衣柜、所有人的裤子放一个大库柜。衣服裤子(对象)，很少的时候很节省空间，**因为你的裤子别人可能也拿去穿，复用一下开发速度很快**。但时间一长，就越来越乱了。🤨 一条裤子被加肥加大，所有人都穿。 + +而 DDD 架构的模型分层，则是以人为视角，**一个人就是一个领域，一个领域内包括他所需的衣服、裤子、袜子、鞋子**。虽然刚开始有点浪费空间，但随着软件的长周期发展，后续的维护成本就会降低。 + +那么，接下来我们就着重看一下，从 MVC 到 DDD 的轻量化重构应该怎么做。🍻 + +>文章后面，含有 MVC 到 DDD 重构编码实践讲解。此文也是 MVC、DDD 的架构编码指导经验说明。 + +## 一、能学到啥 + +本文是偏实战可落地的 DDD 知识分享，也是从 MVC 到 DDD 的可落地方案讲解。在本文中会介绍 DDD 架构下的分层结构、调用全景图以及非常重要的 MVC 到 DDD 应该如何映射和编码。所以如下这一系列内容都是你能获得的知识： + +1. DDD 领域驱动设计，对应的分层结构讲解。涵盖调用关系、依赖关系、对象转换以及各层的功能划分。—— 简单且清晰。 +2. DDD 调用全景图，以一张全方位的结构关系调用视图，展开 DDD 的血脉流转关系。有了这一张视图，你会更加清楚的知道 DDD 的调用链路结构和各个代码都要写到那一层。 +3. MVC 映射 DDD 后的调整方案，在尽可能低的成本下，让 MVC 结构具备 DDD 领域驱动设计的实现思想。这样的调整，可以在一定程度上，阻止旧工程的腐化程度，提高编码质量。同时也为后续从 MVC 到 DDD 的迁移，做好基础。 +4. MVC、DDD 是工程设计骨架，设计原则、设计模式是工程实现血肉。所以设计模式也是本文要展示的重点内容。 +5. 一整套实战开源课程；讲解在 DDD 架构中，各项技术栈：Dubbo、MQ、Redis、Zookeeper - 配置中心等的分层使用。—— 否则你可能都不知道一个 MQ 消息发送要放在哪里。有了 DDD 分层架构，这些东西会被归类的特别清晰。 + +此外，除了这些碎片化的知识学习，还有应用级实战项目锻炼：Lottery DDD 架构设计、ChatGPT 新DDD架构设计、API网关 会话设计 - 学习架构能力和编程思维，以及高端的编码技巧。 + +## 二、架构分层(DDD) + +在 DDD 架构分层中，domain 模块最重要的，也是最大的那个。所有的其他模块都要围着它转。所有 domain 下的各个领域模块，都包含着一组完整的：model - 模型对象、service - 服务处理，以及在有需要操作数据库时，再引入对应的 IRepository - 仓储服务。这个 domain 的实现，就像是实现了一个炸药包，炸药包的火药、引线、包布等都是一个个物料被封装到一起使用。 + +如下是 DDD 架构所呈现出的一种四层架构分层，可能和一些其他的 DDD 分层略有差异，但核心的重点结构是不变的。尤其是 domain 领域、infrastructure 基础，是任何一个 DDD 架构分层都需要有的分层模块。 + +
+ +
+ +- **应用封装 - app**：这是应用启动和配置的一层，如一些 aop 切面或者 config 配置，以及打包镜像都是在这一层处理。你可以把它理解为专门为了启动服务而存在的。 +- **接口定义 - api**：因为微服务中引用的 RPC 需要对外提供接口的描述信息，也就是调用方在使用的时候，需要引入 Jar 包，让调用方好能依赖接口的定义做代理。 +- **领域封装 - trigger**：触发器层，一般也被叫做 adapter 适配器层。用于提供接口实现、消息接收、任务执行等。所以对于这样的操作，这里把它叫做触发器层。 +- **领域编排【可选】 - case**：领域编排层，一般对于较大且复杂的的项目，为了更好的防腐和提供通用的服务，一般会添加 case/application 层，用于对 domain 领域的逻辑进行封装组合处理。但对于一些小项目来说，完全可以去掉这一层。少量一层对象转换，代码的维护成本会降低很多。 +- **领域封装 - domain**：领域模型服务，是一个非常重要的模块。无论怎么做DDD的分层架构，domain 都是肯定存在的。在一层中会有一个个细分的领域服务，在每个服务包中会有【模型、仓库、服务】这样3部分。 +- **仓储服务 - infrastructure**：基础层依赖于 domain 领域层，因为在 domain 层定义了仓储接口需要在基础层实现。这是依赖倒置的一种设计方式。所有的仓储、接口、事件消息，都可以通过依赖倒置的方式进行调用。 +- **外部接口 - gateway**：对于外部接口的调用，也可以从基础设施层分离一个专门的 gateway 网关层，来封装外部 RPC/HTTP 等类型接口的调用。 +- **类型定义 - types**：通用类型定义层，在我们的系统开发中，会有很多类型的定义，包括：基本的 Response、Constants 和枚举。它会被其他的层进行引用使用。(这一层没有画到图中) + +综上就是 DDD 架构思想下的工程分层模型结构，DDD 架构的领域驱动设计的重点包括：结构边界更加清晰、重视上下文调用、分离业务功能与基础支撑。总之一句话，就是各司其职。那么鉴于如此清晰工程结构，该如何将旧存工程，MVC 转向 DDD 呢？接下来就重点介绍下。 + +## 三、工程重构(MVC->DDD) + +经过实践验证，不需要太高成本，MVC 就可以天然的向 DDD 工程分层的模型结构转变。重点是不改变原有的工程模块的依赖关系，将贫血的 domain 对象层，设计为充血的结构。**对于 domain 原本在 MVC 分层结构中，就是一个被依赖层，恰好可以与其他层做依赖倒置的设计方案处理**。具体如图所示： + +
+ +
+ +左侧是我们常见的 MVC 分层结构，右侧是给大家上文讲解过的 DDD 分层结构。从 MVC 到 DDD 的映射，使用了相同颜色进行标注。之后我来介绍一些细节： + +在 MVC 分层结构中，所有的逻辑都集中在 service 层，也是文中提到的腐化最严重的层，要治理的也是这一层。所以首先我们要将 service 里的功能进行拆解。 + +1. service 中具备领域特性的服务实现，抽离到原本贫血模型的 domain 中。在 domain 分层中添加 xxx、yyy、zzz 分层领域包，分别实现不同功能。**注意每个分层领域包内都具备完整的 DDD 领域服务内所需的模块** +2. service 中的基础功能组件，如：缓存Redis、配置中心等，迁移到 dao 层。这里我们把 dao 层看做为基础设施层。它与 domain 领域层的调用关系，为依赖倒置。也就是 domain 层定义接口，dao 层依赖于 domain 定义的接口，做依赖倒置实现接口。 +3. service 本身最后被当做 application/case 层，来调用 domain 层做服务的编排处理。 + +因为恰好，MVC 分层结构中，也是 service 和 dao 依赖于 domain，这和 DDD 分层结构是一致的。所以经过这样的映射拆分代码实现调用结构后，并不会让工程结构发生变化。那么只要工程结构不发生变化，我们的改造成本就只剩下代码编写风格和旧代码迁移成本。 + +MVC 分层结构中的 export 层是 RPC 接口定义层，由 web 层实现。web 是对 service 的调用。也就是 DDD 分层结构中调用 application 编排好的服务。这部分无需改动。**但如果你原有工程把 domain 也暴露出去了，则需要把对应的包迁移到 export** 因为 domain 包有太多的核心对象和属性，还包括数据库持久化对象。这些都不应该被暴露。 + +MVC 分层中，因为有需要对外部 RPC 接口的调用，所以会单独有一层 RPC 来封装其他服务的接口。这一层被 domain 领域层使用，可以定义 adapter 适配器接口，通过依赖倒置，在 rpc 层实现 domain 层定义的调用接口。 + +此外 dao 层，在 MVC 结构中原本是比较单一的。但经过改造后会需要把基础的 Redis 使用、配置中使用，都迁移到 dao 层。因为原本在 service 层的话，domain 层是调用不到的这些基础服务的，而且也不符合服务功能边界的划分。 + +**综上**，就是从 MVC 到 DDD 重构架构的拆解实现方案。这是一种最低成本的最佳实施策略，完全可以保证 MVC 的结构，又可以应用上 DDD 的架构分层优势。也能运用 DDD 领域驱动设计思想，重构旧代码，增加可维护性。 + +到这里，分层结构问题我们说清楚了。从 MVC 调整结构到 DDD 后，工程模型中的调用链路关系是什么样呢？接下来我们再展开架构，看细节关系。 + +## 四、分层调用链路 + +接下来我们把 DDD 的分层架构平铺展开，看看从一个接口的实现到各个模块分层中的调用链路关系是什么样的。这样在做自己的代码开发中也可以参考到应该把什么的功能分配到哪个模块中处理。 + +
+ +
+ +从APP层、触发器层、应用层，这三块主要对领域层的上下文逻辑封装、触发式(MQ、HTTP、JOB)使用，并最终在应用层中打包发布上线。这一部分的都是使用的处理，所以也不会有太复杂的操作。 + +当进入领域层开始，也是智力集中体现的开始了。所有你对工程的抽象能力，都在这一块区域体现。 + +接下来我们着重介绍下领域层和基础层的模块职责功能；**图中下方是对象的流转，可以注意下。** + +### 1. 领域服务层 + +我们可以当 domain 领域层为一个充血模型结构，在一个 domain 领域层中，可以有多个领域包。当然理想状态下，如果你的 DDD 拆分的特别干净的新工程，那么可能一个 domain 就一个领域。但大部分时候微服务的拆分鉴于成本考虑不会那么细，还有一些老工程的重构，都是一个工程内有多个领域，对应的解决方案是在一个工程下建多个同级分层包。比如：账户领域包、授信领域包、结算领域包等，每个包内聚合实现不同的功能。 + +每一个 domain 下的领域包内，都包括：model 模型、仓储、接口、事件和服务的处理。 + +model 模型对象 + +- aggreate：聚合对象，实体对象、值对象的协同组织，就是聚合对象。 +- entity：实体对象，大多数情况下，实体对象(Entity)与数据库持久化对象(PO)是1v1的关系，但也有为了封装一些属性信息，会出现1vn的关系。 +- valobj：值对象，通过对象属性值来识别的对象 By 《实现领域驱动设计》 + +repository 仓储服务：从数据库等数据源中获取数据，传递的对象可以是聚合对象、实体对象，返回的结果可以是：实体对象、值对象。因为仓储服务是由基础层(infrastructure) 引用领域层(domain)，是一种依赖倒置的结构，但它可以天然的隔离PO数据库持久化对象被引用。 + +adapter 接口服务：是依赖于外包的其他 HTTP/RPC 接口的封装调用，通过在 domain 领域层定义适配器接口，再由依赖于 domain 的基础层设施层或者一个单独的专门处理接口的额外分层，来实现 domain 定义的适配器接口，完成对依赖的 HTTP/RPC 进行封装处理。 + +event 事件消息：在服务实现中，经常会有业务完成后，对外发送消息的情况。这个时候，可以在领域模型中定义事件消息的接口，再由基础设施层完成消息的推送。 + +service 服务设计：这里要注意，不要以为定义了聚合对象，就把超越1个对象以外的逻辑，都封装到聚合中，这会让你的代码后期越来越难维护。聚合更应该注重的是和本对象相关的单一简单封装场景，而把一些重核心业务放到 service 里实现。**此外，如果你的设计模式应用不佳，那么无论是领域驱动设计、测试驱动设计还是换了三层和四层架构，你的工程质量依然会非常差。** + +### 2. 基础设施层 + +`提供数据库持久化`、`提供Redis和配置中心数据支撑`、`提供事件消息推送`、`提供外部服务接口封装`。总之这一层的核心目的就是更好的辅助 domain 领域层完成领域功能的开发。 + +而调用方式则为依赖倒置，也就是`领域服务层`定义接口，`基础设施层`做功能实现。这样可以有效的避免基础设施层中的对象被对外暴露，如数据库持久化对象，在这样的分层结构中，天然的被保护在基础设施层中，外部是没法引入的，否则就循环依赖了。 + +有了这一层以后，domain 层不会关心数据的细节处理。传递给基础设施层的方法中，会把聚合对象或实体对象通过接口方法传递下来。之后在基础设施层中完成数据事务的操作。也会含有事务处理后，写入Redis缓存和发送MQ消息。如果说有跨领域的事务，一般可能就是跨库表，这个时候要使用 MQ 事件的方式进行驱动。 + +### 3. 类型对象层 + +这一层就比较简单了，只是一些通用的出入参对象 Response，还有枚举对象、异常对象等。供给于对外的接口层使用。但如果是 RPC 这样的接口，建议同 RPC 对外提供的接口描述包中提供，因为对外只提供1个轻量化的包且不依赖于任何其他包，是最好维护管理的。 + +## 五、只是换了别墅 + +从 MVC 到 DDD，我们有一点是必须清楚的认知的。 + +
+ +
+从 MVC 到 DDD 我们只是换了一个更大、格局更清晰的房子🏡，但并不能决定你从 MVC 到 DDD 代码就变得非常干净、漂亮、整洁了。因为从 MVC 到 DDD 只是骨架变了，但骨架之下的血肉并没有改变。 + +如果你仍是把原有的烂代码平移到新的分层架构中，就相当于把老房子里的破旧家具衣物鞋帽搬过来而已。所以依照于软件设计的原则：分治、抽象和知识，但知识是设计原则和设计模式的运用。所以要想把代码写好，就一定是要把`DDD + 设计模式`，才能真的把代码写好。接下来，小傅哥再给大家举个使用模式在 DDD 分层结构中重构的案例。 + +## 六、重构现有代码 + +软件设计第一原则，康威定律所提到的，分治、抽象和知识，是用于系统设计和实现的指导说明。分治和抽象，我们可以用 DDD 思想映射的分层架构来处理，但知识则是设计原则和设计模式的运用。 + +所以，如果没有合理的运用设计知识来对代码进行细化处理，那么即使拆分出流程边界再清晰的架构，也很难做出好维护的代码。而通常最常用的设计模式，无外乎：工厂、策略、模板的组合使用，少部分会用到责任链、建造者、组合模式。那么接下来，再分享一个带有流程的设计模式使用，让大家可以有一份可参考的工程代码设计。 + +### 1. 场景设定 + +这里我们做一个提额场景的设定。估计大家都用过信用卡💳，它有一个初始的额度，在后续的使用中会随着信用的积累和消费的增加，进行提高额度。而额度的提高则需要一系列的校验判断并最终做出提额处理。流程如下： + +
+ +
+ +这样的流程图，是我们做业务开发的小伙伴，经常看到的。做一系列的流程判断处理，之后完成一个具体的功能。简单来说，就是 if···else 写代码，一条条的校验。但写着写着，时间一长就会发现代码变得特别混乱。最主要的原因就是，那些为了支撑完成业务的各类判断是不稳定因素，会随着业务的变化不断的调整。甚至有时候就直接下掉了。但你的代码中就多了一条 `// 业务说暂时不使用，你也不敢删！`就像有首歌唱的🎤：**“需求依旧停在旷野上，你的代码被越拉越长。直到远去的马蹄声响，呼唤你的Bug传四方。”** + +所以对于这样的功能流程设计，怎么办呢？总不能让旷野的马蹄，一直拉着你的bug在奔袭。 + +### 2. 代码现状 + +`一个接口一个实现，一个实现代码一片。` +`一片一片，又一片，代码行数，两三千。` + +
+ +
+ + +大部分我们在 MVC 工程分层结构下，参与开发的代码，基本都是定义一个接口，就写一片功能实现。功能实现中，如果看到有现成的接口，直接拿来复用。所有的实现并不会基于接口、抽象、模板等进行，所以最终这样的代码腐化的非常严重。 + +### 3. 重新分层 + +重构前，先说明下新的分层处理；如图 + +
+ +
+ +- 首先，在原有的 domain 贫血模型中，添加一个对应的领域包。credit 你可以是自己的其他的领域包。之后的 domain 则为充血模型设计。 +- 之后，在领域包内实现自己的业务逻辑，注意这里需要用到设计模式来实现。代码实现中需要用到的数据查询、缓存使用、接口调用，全部采用依赖倒置的方式让基础层/接口层，来提供具体的实现逻辑。而 domain 层只是定义接口和使用 Spring 的注入进行使用。 + + +### 4. 重构代码 + +抽象类，是一个非常好用的类。一种是可以定义出流程结构，让代码变得清晰干净。再有一种是定义共用方法，让其他实现类可复用。 + +那么这里，我们就使用抽象类定义模板 + 策略和工厂实现的规则引擎处理频繁变动的校验类流程，完成代码开发。如图我们先设计下代码的实现结构。 + +
+ +
+ + +- 首先，定义一个受理调额的接口。因为额度的调整，包括：提额、降额。所以不要把名字写的太死。 +- 之后，由抽象类实现接口。在抽象类中定义出整个调用链路关系，并把一些公用的数据类支撑逻辑，提到支撑类里。这和 Spring 的设计很像。 +- 之后，因为规则校验这东西是为了支撑核心流程走下去的，而且还是随着业务频繁变动的。那就没必要在主线业务流程中，用 if···else 贴膏药的写代码，而是应该拆解出来。所以这里设计一个策略模式实现的规则校验，并通过工厂对外提供服务。 +- 最后，这些零件类的东西都处理好后。就可以在抽象类的子类实现中进行调用处理了。 + +### 5. 代码呈现 + +经过设计模式的重构处理，现在的代码就以如下形式体现了。—— 拆解出来的伪代码，具体可以参考过往的一些设计模式运用。 + +```java +public AdjustAssetOrderEntity acceptAdjustAssetApply(AdjustAssetApplyEntity adjustAssetApplyEntity) { + // 1. 参数校验 + this.parameterVerification(adjustAssetApplyEntity); + + // 2. 查询申请单数据，如已经存在则直接返回 + AdjustAssetOrderEntity orderEntity = queryAssetLog(adjustAssetApplyEntity.getPin(), adjustAssetApplyEntity.getAccountType(), adjustAssetApplyEntity.getTaskNo(), adjustAssetApplyEntity.getAdjustType()); + if (null != orderEntity) { + log.info("pin={} taskNo={} 受理申请，检索到任务存在进行中的申请单。", adjustAssetApplyEntity.getUserId(), adjustAssetApplyEntity.getTaskNo()); + return orderEntity; + } + + // 3. 以下流程放到分布式锁内处理【避免相同请求二次进入】 + String lockId = genLockId(adjustAssetApplyEntity.getAdjustType(), adjustAssetApplyEntity.getUserId()); + try { + // 3.1 分布式锁：加锁 + long state = lock(lockId); + if (0 == state) { + throw new AccountRuntimeException(BizResultCodeEm.DISTRIBUTED_LOCK_EXCEPTION.getCode(), "分布式锁异常，当前用户行为处理中。"); + } + + // 3.2 账户查询 + UserAccountInfoDTO userAccountInfoDTO = queryJtAccount(adjustAssetApplyEntity.getUserId(), adjustAssetApplyEntity.getAccountType()); + + // 3.3 基础校验：(1)账户类型、(2)状态状态、(3)额度类型、(4)账户逾期、(5)费率类型【暂无】 + LogicCheckResultEntity logicCheckResultEntity = doCheckLogic(adjustAssetApplyEntity, userAccountInfoDTO, + DefaultLogicFactory.LogicModel.ACCOUNT_TYPE_FILTER.getCode(), + DefaultLogicFactory.LogicModel.ACCOUNT_STATUS_FILTER.getCode(), + DefaultLogicFactory.LogicModel.ACCOUNT_QUOTA_FILTER.getCode(), + DefaultLogicFactory.LogicModel.ACCOUNT_OVERDUE_FILTER.getCode() + ); + + if (!AssetCycleQuotaAlterCodeEnum.E0000.getCode().equals(logicCheckResultEntity.getCode())) { + log.info("userId={} taskNo={} 规则校验过滤拦截。code:{} info:{}", adjustAssetApplyEntity.getUserId(), adjustAssetApplyEntity.getTaskNo(), logicCheckResultEntity.getCode(), logicCheckResultEntity.getInfo()); + throw new AccountRuntimeException(logicCheckResultEntity.getCode(), logicCheckResultEntity.getInfo()); + } + + // 3.4 受理调额 + return this.acceptAsset(adjustAssetApplyEntity, userAccountInfoDTO); + } finally { + // 3.1 分布式锁：解锁 + this.unlock(lockId); + } +} +``` + +这样的处理后，代码就变得非常清晰了。 + +1. 先是做基础的校验和数据的查询判断，之后加锁避免一个人超时申请。而后，进行规则引擎的调用和处理，根据不同的诉求，开发不同的规则，并配置的方式进行使用。 +2. 最后所有的这些东西处理完成后，就是做最终的调额处理了。 + +## 七、编程经验 + +- 重构，是一直都在发生的事情，不能积累到最后才重构。那只有重做的可能。 +- 工厂、模板、策略，这3个设计模式，就可以解决80%的场景问题。 +- 小傅哥的编码标准也会成为伙伴参考的案例，所以小傅哥会更严格要求自己的标准。 diff --git a/docs/md/road-map/mybatis.md b/docs/md/road-map/mybatis.md new file mode 100644 index 000000000..37ec011c2 --- /dev/null +++ b/docs/md/road-map/mybatis.md @@ -0,0 +1,488 @@ +--- +title: MyBatis +lock: need +--- + +# MyBatis 使用教程和插件开发 + +作者：小傅哥 +

+ +此场景的业务用于对指定的用户进行**晋升加薪调幅**，但因为加薪会需要操作3个表，包括：雇员表 - 修改个人Title、薪资表 - 修改薪酬、调薪记录表 - 每一次加薪都写一条记录。 + +### 1. model + +#### 1.1 值对象 + +```java +public enum EmployeePostVO { + + T1("T-1", "初级工程师"), + T2("T-2", "初级工程师"), + T3("T-3", "中级工程师"), + T4("T-4", "中级工程师"), + T5("T-5", "高级工程师"), + T6("T-6", "高级工程师"), + T7("T-7", "架构师"), + T8("T-8", "架构师"); + + private final String code; + private final String desc; + + // 省略部分 + +} +``` + +- 当一个实体对象中的一个值，是有多个范围时候，则需要定义出值对象。由于此类的值对象更贴近于当前的场景业务，所以一般不会被定义为共用的枚举。如此此类值范围，都会被定义为值对象。 + +#### 1.2 实体对象 + +```java +@Data +@Builder +@AllArgsConstructor +@NoArgsConstructor +public class EmployeeEntity { + + /** 雇员级别 */ + private EmployeePostVO employeeLevel; + /** 雇员岗位Title */ + private EmployeePostVO employeeTitle; + +} + +@Data +@Builder +@AllArgsConstructor +@NoArgsConstructor +public class EmployeeSalaryAdjustEntity { + + /** 总额调薪 */ + private BigDecimal adjustTotalAmount; + /** 基础调薪 */ + private BigDecimal adjustBaseAmount; + /** 绩效调薪 */ + private BigDecimal adjustMeritAmount; + +} +``` + +- 实体对象是对数据库对象的抽象，大多数时候是 1:1 的关系结构，在一些复杂的模型场景中会是1:n的结构。 + +#### 1.3 聚合对象 + +```java +@Data +@Builder +@AllArgsConstructor +@NoArgsConstructor +public class AdjustSalaryApplyOrderAggregate { + + /** 雇员编号 */ + private String employeeNumber; + /** 调薪单号 */ + private String orderId; + /** 雇员实体 */ + private EmployeeEntity employeeEntity; + /** 雇员调薪实体 */ + private EmployeeSalaryAdjustEntity employeeSalaryAdjustEntity; + +} +``` + +- 聚合对象是对实体对象和值对象的封装，代表着一类业务的聚合。通常是作为 service 服务层中入参出现。 + +### 2. repository + +```java +public interface ISalaryAdjustRepository { + + String adjustSalary(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate); + +} +``` + +- 仓储在 DDD 中的设计，是一种依赖倒置关系，由 domain 定义接口，之后由引入 domain 包的基层层 infrastructure 实现功能。 +- 此外，因为是依赖倒置，所以天然的隔离了 PO 数据库持久化对象，不会被对外使用。这个设计是非常巧妙的。当我们从结构上定义了原则，就不会有人乱引用对象了。 + +### 3. service + +```java +public interface ISalaryAdjustApplyService { + + String execSalaryAdjust(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate); + +} +``` + +- 当前场景简单，所以不需要额外的设计模式使用。但如果是复杂场景，必须考虑设计模式，否则代码都写到 SalaryAdjustApplyService 实现类里，那么将非常难维护。 +- 不要只是把聚合对象当充血模型，你的充血结构是整个 domain 下的每一个领域包，也就是让这里的状态与行为看做为一整个结构。 + +📢 **综上**，有了这样的模型结构设计定义，相信你也可以很好的拆分自己的业务对象并完成领域功能实现了。 + +## 三、配置文件 + +
+ +
+ +- 工程中关于 MyBatis 的使用，在 xfg-dev-tech-app 下进行统一配置。因为所有配置信息都放到一起，比较方便管理，也利于线上上线后，提取配置文件。 + +## 四、功能实现 + +接下来我们介绍一些关于 MyBatis 的使用功能，但你可以带着 DDD 的思想来看这些内容实现时所在的位置，这会让你不只是学习 MyBatis 也能学会一些 DDD 的设计。 + +### 1. 插入&批量插入 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.dao.IEmployeeDAO` + +```java +@Mapper +public interface IEmployeeDAO { + + void insert(EmployeePO employee); + + void insertList(List list); + + void update(EmployeePO employeePO); + + EmployeePO queryEmployeeByEmployNumber(String employNumber); + +} +``` + +**xml**：`employee_mapper.xml` + +```xml + + INSERT INTO employee(employee_number, employee_name, employee_level, employee_title, create_time, update_time) + VALUES(#{employeeNumber}, #{employeeName}, #{employeeLevel}, #{employeeTitle}, now(), now()) + + + + INSERT INTO employee(employee_number, employee_name, employee_level, employee_title, create_time, update_time) + VALUES + + (#{item.employeeNumber}, #{item.employeeName}, #{item.employeeLevel}, #{item.employeeTitle}, now(), now()) + + +``` + +- 使用配置文件的方式比较好维护，当然也可以尝试使用 MyBatis 提供的注解方式，完成数据的操作。 + +### 2. 事务&注解编程 + +Spring 提供的事务分为注解事务和编程事务，编程事务可以更细粒度的控制。 + +Spring Boot 事务管理的级别可以通过 `@Transactional` 注解的 `isolation` 属性进行配置。常见的事务隔离级别有以下几种： + +1. `DEFAULT`：使用底层数据库的默认隔离级别。MySQL 默认为 `REPEATABLE READ`，Oracle 默认为 `READ COMMITTED`。 +2. `READ_UNCOMMITTED`：最低的隔离级别，允许读取未提交的数据变更，可能会导致脏读、不可重复读和幻读问题。 +3. `READ_COMMITTED`：允许读取已经提交的数据变更，可以避免脏读问题，但可能会出现不可重复读和幻读问题。 +4. `REPEATABLE_READ`：保证同一事务中多次读取同一数据时，结果始终一致，可以避免脏读和不可重复读问题，但可能会出现幻读问题。 +5. `SERIALIZABLE`：最高的隔离级别，可以避免脏读、不可重复读和幻读问题，但会影响并发性能。 + +在 Spring Boot 中，默认的事务隔离级别为 `DEFAULT`。如果没有特殊需求，建议使用默认隔离级别。 + +SpringBoot 事务的传播行为可以通过 `@Transactional` 注解的 `propagation` 属性进行配置。常用的传播行为有以下几种： + +1. `Propagation.REQUIRED`：默认的传播行为，如果当前存在事务，则加入该事务，否则新建一个事务； +2. `Propagation.SUPPORTS`：如果当前存在事务，则加入该事务，否则以非事务的方式执行； +3. `Propagation.MANDATORY`：如果当前存在事务，则加入该事务，否则抛出异常； +4. `Propagation.REQUIRES_NEW`：无论当前是否存在事务，都会新建一个事务，如果当前存在事务，则将当前事务挂起； +5. `Propagation.NOT_SUPPORTED`：以非事务的方式执行操作，如果当前存在事务，则将当前事务挂起； +6. `Propagation.NEVER`：以非事务的方式执行操作，如果当前存在事务，则抛出异常； +7. `Propagation.NESTED`：如果当前存在事务，则在该事务的嵌套事务中执行，否则新建一个事务。嵌套事务是独立于外部事务的，但是如果外部事务回滚，则嵌套事务也会回滚。 + +除了传播行为，`@Transactional` 注解还可以配置其他属性，例如隔离级别、超时时间、只读等。 + +#### 2.1 注解事务 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.repository.SalaryAdjustRepository` + +```java +@Transactional(rollbackFor = Exception.class, timeout = 350, propagation = Propagation.REQUIRED, isolation = Isolation.DEFAULT) +public String adjustSalary(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate) { + String employeeNumber = adjustSalaryApplyOrderAggregate.getEmployeeNumber(); + String orderId = adjustSalaryApplyOrderAggregate.getOrderId(); + EmployeeEntity employeeEntity = adjustSalaryApplyOrderAggregate.getEmployeeEntity(); + EmployeeSalaryAdjustEntity employeeSalaryAdjustEntity = adjustSalaryApplyOrderAggregate.getEmployeeSalaryAdjustEntity(); + EmployeePO employeePO = EmployeePO.builder() + .employeeNumber(employeeNumber) + .employeeLevel(employeeEntity.getEmployeeLevel().getCode()) + .employeeTitle(employeeEntity.getEmployeeTitle().getDesc()).build(); + // 更新岗位 + employeeDAO.update(employeePO); + EmployeeSalaryPO employeeSalaryPO = EmployeeSalaryPO.builder() + .employeeNumber(employeeNumber) + .salaryTotalAmount(employeeSalaryAdjustEntity.getAdjustTotalAmount()) + .salaryMeritAmount(employeeSalaryAdjustEntity.getAdjustMeritAmount()) + .salaryBaseAmount(employeeSalaryAdjustEntity.getAdjustBaseAmount()) + .build(); + // 更新薪酬 + employeeSalaryDAO.update(employeeSalaryPO); + EmployeeSalaryAdjustPO employeeSalaryAdjustPO = EmployeeSalaryAdjustPO.builder() + .employeeNumber(employeeNumber) + .adjustOrderId(orderId) + .adjustTotalAmount(employeeSalaryAdjustEntity.getAdjustTotalAmount()) + .adjustBaseAmount(employeeSalaryAdjustEntity.getAdjustMeritAmount()) + .adjustMeritAmount(employeeSalaryAdjustEntity.getAdjustBaseAmount()) + .build(); + // 写入流水 + employeeSalaryAdjustDAO.insert(employeeSalaryAdjustPO); + return orderId; +} +``` + +- 这个事务所做的内容，就是前面小傅哥提到的调整薪资的处理。它的具体操作就是放到仓储层实现。 +- 注意事务注解的配置。 + +#### 2.2 编程事务 + +##### 2.2.1 事务模板 + +
+ +
+ +- 使用编程事务，需要在这里创建出一个事务模板，当然你不创建也可以使用。只不过这样统一的配置会更加方便。 + +##### 2.2.2 事务使用 + +```java +private TransactionTemplate transactionTemplate; +@Override +public void insertEmployeeInfo(EmployeeInfoEntity employeeInfoEntity) { + transactionTemplate.execute(new TransactionCallbackWithoutResult() { + @Override + protected void doInTransactionWithoutResult(TransactionStatus status) { + try { + EmployeePO employeePO = EmployeePO.builder() + .employeeNumber(employeeInfoEntity.getEmployeeNumber()) + .employeeName(employeeInfoEntity.getEmployeeName()) + .employeeLevel(employeeInfoEntity.getEmployeeLevel()) + .employeeTitle(employeeInfoEntity.getEmployeeTitle()) + .build(); + employeeDAO.insert(employeePO); + EmployeeSalaryPO employeeSalaryPO = EmployeeSalaryPO.builder() + .employeeNumber(employeeInfoEntity.getEmployeeNumber()) + .salaryTotalAmount(employeeInfoEntity.getSalaryTotalAmount()) + .salaryMeritAmount(employeeInfoEntity.getSalaryMeritAmount()) + .salaryBaseAmount(employeeInfoEntity.getSalaryBaseAmount()) + .build(); + employeeSalaryDAO.insert(employeeSalaryPO); + } catch (Exception e) { + status.setRollbackOnly(); + e.printStackTrace(); + } + } + }); +} +``` + +- 之后就可以手动处理事务了，因为手动的处理可以更细节的控制，也可以根据返回的结果，手动回滚。而不非得异常回滚。 + +### 3. 插件&数据加密 + +使用 MyBatis 时，也会经常会用到插件开发。尤其是做一些数据的加解密、路由、日志等，都可以基于插件实现。 + +那么这里小傅哥就带着你实现一个对指定字段加解密的处理，比如雇员的姓名、薪资、级别是可以隐藏的，避免被有心之人盗取。 + +**源码**：`cn.bugstack.xfg.dev.tech.plugin.FieldEncryptionAndDecryptionMybatisPlugin` + +```java +@Intercepts({ + @Signature(type = Executor.class, method = "update", args = {MappedStatement.class, Object.class}), + @Signature(type = Executor.class, method = "query", args = {MappedStatement.class, Object.class, RowBounds.class, ResultHandler.class}) +}) +public class FieldEncryptionAndDecryptionMybatisPlugin implements Interceptor { + + /** + * 密钥，必须是16位 + */ + private static final String KEY = "1898794876567654"; + /** + * 偏移量，必须是16位 + */ + private static final String IV = "1233214566547891"; + + @Override + public Object intercept(Invocation invocation) throws Throwable { + Object[] args = invocation.getArgs(); + MappedStatement mappedStatement = (MappedStatement) args[0]; + Object parameter = args[1]; + String sqlId = mappedStatement.getId(); + + if (parameter != null && (sqlId.contains("insert") || sqlId.contains("update")) ) { + String columnName = "employeeName"; + if (parameter instanceof Map) { + List parameterList = (List) ((Map) parameter).get("list"); + for (Object obj : parameterList) { + if (hasField(obj, columnName)) { + String fieldValue = BeanUtils.getProperty(obj, columnName); + String encryptedValue = encrypt(fieldValue); + BeanUtils.setProperty(obj, columnName, encryptedValue); + } + } + } else { + if (hasField(parameter, columnName)) { + String fieldValue = BeanUtils.getProperty(parameter, columnName); + String encryptedValue = encrypt(fieldValue); + BeanUtils.setProperty(parameter, columnName, encryptedValue); + } + } + } + + Object result = invocation.proceed(); + + if (result != null && sqlId.contains("query")) { + // 查询操作，解密 + String columnName = "employeeName"; + if (result instanceof List) { + List resultList = (List) result; + for (Object obj : resultList) { + if (!hasField(obj, columnName)) continue; + String fieldValue = BeanUtils.getProperty(obj, columnName); + if (StringUtils.isBlank(fieldValue)) continue; + String decryptedValue = decrypt(fieldValue); + BeanUtils.setProperty(obj, columnName, decryptedValue); + } + } + } + + return result; + } + + public String encrypt(String content) throws Exception { + Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); + byte[] raw = KEY.getBytes(); + SecretKeySpec secretKeySpec = new SecretKeySpec(raw, "AES"); + IvParameterSpec ivParameterSpec = new IvParameterSpec(IV.getBytes()); + cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivParameterSpec); + byte[] encrypted = cipher.doFinal(content.getBytes()); + return Base64.getEncoder().encodeToString(encrypted); + } + + /** + * AES解密 + * + * @param content 密文 + * @return 明文 + * @throws Exception 异常 + */ + public String decrypt(String content) throws Exception { + Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); + byte[] raw = KEY.getBytes(); + SecretKeySpec secretKeySpec = new SecretKeySpec(raw, "AES"); + IvParameterSpec ivParameterSpec = new IvParameterSpec(IV.getBytes()); + cipher.init(Cipher.DECRYPT_MODE, secretKeySpec, ivParameterSpec); + byte[] encrypted = Base64.getDecoder().decode(content); + byte[] original = cipher.doFinal(encrypted); + return new String(original); + } + + public boolean hasField(Object obj, String fieldName) { + Class clazz = obj.getClass(); + while (clazz != null) { + try { + Field field = clazz.getDeclaredField(fieldName); + return true; + } catch (NoSuchFieldException e) { + clazz = clazz.getSuperclass(); + } + } + return false; + } + +} +``` + +

+ +
+ +**有些事故隐藏的很深！** + +其实很多时候事故也不是一开始就有的，而是随着需求的迭代，达到某一个条件后触达到事故的发生条件了才出现的。就像 MySQL 的时区配置问题，它既有不同版本 JDBC 连接引擎的不同，又有数据库设置的时区，还有服务端设置的时区，还包括在使用数据库配置时指定的时区。这些条件综合发生时才会出现事故。 + +接下来，小傅哥就给大家分享下为啥是 8.0.22 版本才会引发时区错误问题。 + +## 一、问题场景 + +这是一条很普通的SQL语句； + +```java + + INSERT INTO employee(employee_number, employee_name, employee_level, employee_title, create_time, update_time) + VALUES(#{employeeNumber}, #{employeeName}, #{employeeLevel}, #{employeeTitle}, now(), now()) + +``` + +修改下这条普通的SQL语句； + +```java + + INSERT INTO employee(employee_number, employee_name, employee_level, employee_title, create_time, update_time) + VALUES(#{employeeNumber}, #{employeeName}, #{employeeLevel}, #{employeeTitle}, #{createTime}, now()) + +``` + +接下来在执行插入SQL语句； + +
+ +
+ +- 原本直接使用数据库语句 now() 的并没有问题，而改为由程序透传的时间 createTime 后，日期时间发生了错误。差了8个小时。 +- 通常一般我们操作数据库的时候，写入的时间，往往都是 now()。但有时候比如要外部透传用户下单时间做本系统做一个返利活动，在什么时间内才返利，要记录时间。这个时候发现写入数据库的时间就不对了。 +- 因为原本你的系统都是走的数据库时间，现在突然多了一个来自系统的透传时间，那么你可能是注意不到的。另外由于本机的开发环境与服务器配置不一样，所以最终直至上线开始跑数据了，才发现问题。这个就是一般出现事故的原因。 + +## 二、排查配置 + +### 1. mysql jdbc 版本 + +```java + + mysql + mysql-connector-java + 8.0.22 + +``` + +- 8.0.22 版本，官网提示有bug；`https://dev.mysql.com/doc/relnotes/connector-j/en/news-8-0-23.html` + +### 2. 链接参数配置 + +```java +jdbc:mysql://127.0.0.1:3306/road-map?useUnicode=true&characterEncoding=utf8&autoReconnect=true&zeroDateTimeBehavior=convertToNull&useSSL=true +``` + +- 注意首次没有配置时区。配置时区需要增加参数；`&serverTimezone=Asia/Shanghai` + +### 3. mysql time-zone 配置 + +```java +show variables like '%time_zone%'; + ++------------------+--------+ +| Variable_name | Value | ++------------------+--------+ +| system_time_zone | CST | +| time_zone | SYSTEM | ++------------------+--------+ +``` + +- 命令修改时区；`SET time_zone = 'SYSTEM';` +- 命令修改时区；`SET time_zone = '+8:00';` +- 注意CST配置，不是中国时区。默认是美国中部时间。 + - 美国中部时间 Central Standard Time (USA) UTC-05:00 或 UTC-06:00 + - 澳大利亚中部时间 Central Standard Time (Australia) UTC+09:30 + - 中国标准时 China Standard Time UTC+08:00 + - 古巴标准时 Cuba Standard Time UTC-04:00 + + +### 4. linux 服务器时间 + +```java +[root@lavm-aqhgp9nber ~]# timedatectl + Local time: Sat 2024-08-31 13:57:07 CST + Universal time: Sat 2024-08-31 05:57:07 UTC + RTC time: Sat 2024-08-31 05:57:06 + Time zone: Asia/Shanghai (CST, +0800) + NTP enabled: yes +NTP synchronized: yes + RTC in local TZ: no + DST active: n/a +``` + +- 命令修改时区；`sudo timedatectl set-timezone Asia/Shanghai` +- 命令修改时区；`sudo timedatectl set-timezone America/New_York` + +## 三、源码问题 - MySQL JDBC + +### 1. 8.0.22 版本问题 + +在 8.0.0 ~ 8.0.22 版本中，如果未配置时区，`serverTimezone=Asia/Shanghai` 则会取服务端时区，所以如果服务端配置的是 CST 时区，则会有问题。调试源码； + +**com.mysql.cj.protocol.a.NativeProtocol#configureTimezone** + +

It was because while Connector/J 5.1 does not preserve a time instant by default, Connector/J 8.0.22 and earlier tried to do so by converting a timestamp to the server's session time zone before sending its value to the server. In this release, new mechanisms for controlling timezone conversion has been introduced—see Preserving Time Instants for details. Under this new mechanism, the default behavior of Connector/J 5.1 in this respect is preserved by setting the connection property preserveInstants=false.

+ +
+ +如上所列规范包括：建表相关规范、字段相关规范、索引相关规范、使用相关规范。 + +### 1. 建表相关规范 + +1. 库名、表名、字段名，使用小写和下划线 _ 分割 +2. 库名、表名、字段名，不超过12个字符。默认支持64个字符。 +3. 库名、表名、字段名，见名知意，建议使用名词而不是动词。 +4. 使用 InnoDB 存储引擎。支持；事务、锁、高并发 性能好。 +5. 推荐使用 utf8mb4 可以存emoji +6. 单表字段数，建议不超过40个 + +### 2. 字段相关规范 + +1. 整型定义中不显示设置长度，如使用 INT，而不是INT(4) +2. 存储精度浮点数，使用 DECIMAL 替代 FLOAT、DOUBLE +3. 所有字段，都要有 Comment 描述 +4. 所有字段应定义为 NOT NULL +5. 超过2038年，用DATETIME存储 +6. 短数据类型 0~80 选用 TINYINT 存储 +7. UUID 有全局唯一统一字段属性，适合做同步ES使用。 +8. IPV4，用无符号 INT 存储 +9. IPV6，用VARBINARY存储 +10. JSON MySql 8.x 新增特性 +11. update_time 设置 on update 更新属性 + +### 3. 索引相关规范 + +1. 要求有自增ID作为主键，不要使用随机性较强的 order_id 作为主键，会导致innodb内部page分裂和大量随机I/O，性能下降。 +2. 单表索引建议控制在5个以内，单索引字段数不超过5个。注意：已有idx(a, b)索引，又有idx(a)索引，可以把idx(a)删了，浪费空间，降低更新、写入性能。* 单个索引中，每个索引记录的长度不能超过64KB +3. 利用覆盖索引来进行查询操作，避免回表。另外建组合索引的时候，区分度最高的在最左边。 +4. `select(count(distinct(字段)))/count(id) = 1` 的区分度，更适合建索引。在一些低区分度的字段，例如type、status上建立独立索引几乎没意义，降低更新、写入性能。 +5. 防止因字段不同造成的隐式转换，导致索引失效。 +6. 更新频繁的字段，不要建索引。 + +### 4. 使用相关规范 + +1. 单表数据量不超过500万行，ibc 文件大小不超过 2G +2. 水平分表用取模，日志、报表类，可以用日期 +3. 单实例表数目小于 500 +4. alter表之前，先判断表数据量，对于超过100W行记录的表进行alter table，必须在业务低峰期执行。因为alter table会产生表锁，期间阻塞对于该表的所有写入 +5. SELECT语句必须指定具体字段名称，禁止写成 `“*”select *` 会将不需要读的数据也从MySQL里读出来，造成网卡压力，数据表字段一旦更新，但model层没有来得及更新的话，系统会报错 +6. insert语句指定具体字段名称，不要写成 `insert into t1 values(…)` +7. `insert into…values(XX),(XX),(XX)..` 这里XX的值不要超过5000个，值过多会引起主从同步延迟变大。 +8. `union all` 和 `union`，不要超过5个子句，如果没有去重的需求，使用union all性能更好。 +9. in 值列表限制在500以内，例如 `select… where userid in(….500个以内…)`，可以减少底层扫描，减轻数据库压力。 +10. 除静态表或小表（100行以内），DML语句必须有where条件，且尽量使用索引查找 +11. 生产环境禁止使用 hint，如 sql_no_cache，force index，ignore key，straight join等。 +要相信MySQL优化器。hint是用来强制SQL按照某个执行计划来执行，但随着数据量变化我们无法保证自己当初的预判是正确的。 +12. where条件里，等号左右字段类型必须一致，否则会造成隐式的类型转化，可能导致无法使用索引 +13. 生产数据库中强烈不推荐在大表执行全表扫描，查询数据量不要超过表行数的25%，否则可能导致无法使用索引 +14. where子句中禁止只使用全模糊的LIKE条件进行查找，如like ‘%abc%’，必须有其他等值或范围查询条件，否则可能导致无法使用索引 +15. 索引列不要使用函数或表达式，如 `where length(name)=10` 或 `where user_id+2=1002`，否则可能导致无法使用索引 +16. 减少使用or语句 or有可能被 mysq l优化为支持索引，但也要损耗 mysql 的 cpu 性能。可将or语句优化为union，然后在各个where条件上建立索引。如 `where a=1 or b=2` 优化为 `where a=1… union …where b=2, key(a),key(b)` 某些场景下，也可优化为 `in` +17. 分页查询，当limit起点较高时，可先用过滤条件进行过滤。如 `select a,b,c from t1 limit 10000,20`; 优化为 `select a,b,c from t1 where id>10000 limit 20`; +18. 同表的字段增删、索引增删等，合并成一条DDL语句执行，提高执行效率，减少与数据库的交互。 +19. `replace into` 和 `insert on duplicate key update` 在并发环境下执行都可能产生死锁（后者在5.6版本可能不报错，但数据有可能产生问题），需要catch异常，做事务回滚，具体的锁冲突可以关注`next key lock`和`insert intention lock` +20. TRUNCATE TABLE 比 DELETE 速度快，且使用的系统和事务日志资源少，但 TRUNCATE 无事务且不触发 trigger ，有可能造成事故，故不建议在开发代码中使用此语句。说明： TRUNCATE TABLE 在功能上与不带 WHERE 子句的 DELETE 语句相同。 + +## 三、建表语句 + +**环境说明**； + +- MySQL 8.0.32 - 可使用 Docker 安装，脚本放到本案例仓库了。 +- [Sequel Ace](https://www.sequelpro.com/) + +```sql +# ************************************************************ +# Sequel Ace SQL dump +# 版本号： 20050 +# +# https://sequel-ace.com/ +# https://github.com/Sequel-Ace/Sequel-Ace +# +# 主机: localhost (MySQL 8.0.32) +# 数据库: road_map +# 生成时间: 2023-08-12 07:19:03 +0000 +# ************************************************************ + + +/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +在这之前我犹豫🦑了好久，一台不错的 Nas 四五千块，买这个东西能帮助我啥呢 🤔？但后来发现，这台 2c8g 双盘位 4TB Nas，等同于个人拥有了一台永久可用的，软件丰富的，具备远程访问能力的，终身 Linux 服务器。 + +
+ +
+ +**谁更适合买一台 Nas？** + +虽然 Nas 确实很不错，但也不是所有人都有诉求，也不用都买很高配置很贵的。那谁有 Nas 诉求呢？家里有娃的，有大量的照片、视频、文件，需要家人一起存储使用。另外是喜欢看4k蓝光电影，可以用 Nas 搭建一套家庭影院。很多 Nas 也是主打这些功能。 + +但其实我买 Nas，有上面的功能诉求，但还有作为程序员👨🏻‍💻的编程诉求。我希望能在这台 Nas 上安装 Docker 部署环境，并能通过 SSH 客户端，以使用 Linux 的方式，连接 Nas 完成项目的构建、镜像打包和部署。 + +>嘿嘿，使用起来，它还真可以！不过，别买错 Nas，有些并不支持！ + +## 一、Nas 是啥？ + +NAS（Network Attached Storage，网络附加存储）是一种通过标准的网络拓扑结构（例如以太网）连接到一群计算机上的存储设备。它是一种具有很大存储容量的电脑外敷设备，通过集线器或交换机直接连在网络上，提供跨平台文件共享功能。 + +更简单的来讲，你就把它当做一台部署在家里的 Linux 服务器就好，只不过它的体积不大，但有很大的硬盘容量。所有开通了权限的用户，都可以使用这台共享服务器。并且它提供了很多的软件资源和网络访问服务。 + +## 二、买的哪家的 Nas？ + +市面的 Nas 有很多，如；群晖、威联通、绿联、极空间、华为。它们到没有绝对的谁家好，只不过有会一些目标人群的不同。有一些网上的对比，可以参考； + +| 品牌 | 优势 | 劣势 | +|----------|----------------------------------------------------------------------|----------------------------------------------------------------------| +| 群晖 | - 软件生态丰富，DSM系统用户友好 | - 价格较高 | +| | - 稳定性和可靠性强 | - 硬件规格在同价位上可能不如竞争对手 | +| | - 拥有庞大的用户社区和丰富的在线资源 | | +| | - 提供多种数据保护和备份解决方案 | | +| 威联通 | - 硬件性能强，提供更高的硬件规格 | - 软件复杂性较高，新手用户可能较难上手 | +| | - 支持虚拟化、容器化应用和多媒体功能 | - 某些情况下软件更新可能导致系统不稳定 | +| | - 提供丰富的扩展选项 | | +| 绿联 | - 价格实惠，适合预算有限的用户 | - 功能较为基础，适合简单存储需求 | +| | - 简单易用，适合家庭用户和小型办公室 | - 在NAS市场的知名度和用户基础不如群晖和威联通 | +| 极空间 | - 性价比高，适合中小企业和个人用户 | - 软件生态和用户界面不如群晖和威联通成熟 | +| | - 提供较为合理的硬件配置 | - 相对较小的用户社区和技术支持资源 | + + +我买的是一台 `群晖 DS723+` 并配了`8G内存` + `2*2TB`硬盘互备，因为咱们要做 Docker 安装各类软件，内存大一些更好。选择群晖主要就是想着这东西资源丰富，可以像使用 Linux 服务器一样使用 Nas 满足开发和存储需求。 + +
+ +
+ +> 用了群晖 Nas 有5个月了，越用越爽。电脑里的东西基本都搬到群晖了，电脑只成为一个工具了，不在搞那么多存储。 + +## 三、Nas 的编程用途 + +群晖 Nas 提供了 群晖管家 APP，只要开启 QuickConnect，无论在家内网还是外网都可以访问和管理 Nas。另外群晖还提供了专门做照片和视频同步管理的 Photos Mobile APP 你可以直接下载使用。 + +它所有的这些东西，只要对照提供的说明书都可以下载使用。难度极低，很好上手。这里小傅哥主要给大家分享下编程的用途。 + +这里首先，对于使用 Windows 的小伙伴，如果你有台 Nas，就不需要本地做那么多让 Windows 兼容 Linux 的事情了。你可以直接在这个上面安装提供的 Docker 套件，并完成对应用程序的打包、构建以及 PUSH 镜像到 DockerHub。 + +另外就是很多小伙伴的电脑配置不高，容量也不大，可以考虑购买 Nas 分摊一部分本身电脑的压力。就像我，如果开启多个 IntelliJ IDEA，在开启 Docker 提供分布式软件环境、在搞一堆网页，以及开启视频录制。这个时候就会非常卡顿了。所以我搞了台 Nas 来解决这个事情。 + +### 1. 有很多编程软件 + +群晖 Nas 提供了非常多的配套软件，适合于不同场景诉求的伙伴使用。所以很多买群晖的伙伴都说，是买软件送设备。嘿嘿，不过我更喜欢这部分编程相关的，尤其是这个 Docker、Git Server，嗖的就安装好。 + +
+ +
+ +- Nas 还支持配置定时开机关机、休眠，这样会比较省电，也不用一直在那打开着。 +- 另外可以自建frp，让自己的nas服务可以直接被公网访问。一年￥48 2c2g 服务器即可。[https://618.gaga.plus](https://618.gaga.plus) 专属地址。[frp](https://bugstack.cn/md/road-map/frp.html) 教程在 bugstack.cn - 路书中。 + +### 2. Docker 使用 + +
+ +
+ +
+ +
+ +- 你可以在提供的操作界面配置 Docker Compose，完成项目文件的配置和启动。之后的体验就和正常 Linux 安装 Docker 部署软件一样了。 +- 不过我通常把这里都只是作为配置后的操作界面，配置的操作，我会在用SSH工具直接链接到Nas上。 + +### 3. SSH 连接 Nas + +因为本身 Nas 也是一台 Linux 服务器，所以可以直接用 SSH 连接使用。推荐使用 [https://termius.com/](https://termius.com/) 工具链接，很好用。 + +- 账号：你的 Nas 登录账号 +- 密码：你的 Nas 登录密码 + +
+ +
+ +登录以后，你就可以像使用 Linux 一样操作了，不过大部分执行类命令，要加上 sudo，比如 `sudo docker images` + +### 4. 构建项目 + +有了 Nas 有个很大的好处就是，你可以本地直接当 Nas 的硬盘是本地的一个文件夹，直接打开就操作。里面的文件直接复制粘贴进去或者拿出来就可以。 + +
+ +

+ +
+ +**自己部署的 DeepSeek 功能还挺多！** + +自己基于 Ollama 部署的一套 DeepSeek，可以提供独属于你自己一套的 AI，并且可以做图片识别、联网、知识库。而且如果你是一个需要使用 DeepSeek 接口做开发的码农，还可以直接使用自己提供的这套 API 做开发。 + +接下来，小傅哥就带着你使用 Docker 完成 Ollama 的安装和 DeepSeek 模型的部署。Docker 可以在任何环境执行，小傅哥自己是放到 Nas 环境里部署。部署完成后，安装谷歌浏览器插件 Page Assist 使用 Ollama 部署的 DeepSeek 模型。 + +## 一、部署脚本 + +小傅哥这里为你提供了执行安装的脚本，以及测试API的方法； + +
+ +
+ +- 代码：[https://github.com/fuzhengwei/xfg-dev-tech-ollama](https://github.com/fuzhengwei/xfg-dev-tech-ollama) +- dev-ops，提供了 docker-compose.yml 部署 ollama 脚本。这个文件你可以放到任何安装了 Docker 的环境里执行。 +- src 代码，提供的是测试这套 Ollama 下的大模型。除了你本节部署的 DeepSeek，以后部署其他的也可以这样使用。 + +## 二、部署安装 + +### 1. 执行脚本 + +
+ +
+ +```java +# docker compose -f docker-compose.yml up -d +version: '3.8' +services: + ollama: +# image: ollama/ollama:0.5.10 + image: registry.cn-hangzhou.aliyuncs.com/xfg-studio/ollama:0.5.10 + container_name: ollama + restart: unless-stopped + ports: + - "11434:11434" +``` + +- 原始镜像 `image: ollama/ollama:0.5.10` 代理镜像 `registry.cn-hangzhou.aliyuncs.com/xfg-studio/ollama:0.5.10` +- Nas 可以通过界面操作执行启动，如果你是 Linux 服务器，安装了 Docker，可以使用命令执行 `docker compose -f docker-compose.yml up -d` + +### 2. 模型说明 - DeepSeek + +| 模型 | 内存 | 存储 | 特点 | +| ---------------- | ---- | ------ | ---------------------------------------------------- | +| deepseek-r1:1.5b | 8G | 12GB | 轻量级模型，运行速度快，性能有限。 | +| deepseek-r1:7b | 16G | 80GB | 平衡型模型，性能较好，硬件需求适中。 | +| deepseek-r1:14b | 32G | 200GB | 高性能模型，擅长复杂任务（数学推理，代码生成） | +| deepseek-r1:32b | 64G | 320GB | 专业级模型，性能强大，适合高精度任务 | +| deepseek-r1:70b | 128G | 500GB+ | 顶级模型，性能最强，适合大规模计算和高复杂任务执行。 | + +- 这里小傅哥选择的是 1.5b 模型，你可以按照自己的机器配置进行选择。 + +### 3. 模型安装 - DeepSeek + +你需要进入到 Ollama 管理后台执行安装模型脚本； + +
+ +
+ +```java +# 拉取模型 +ollama pull deepseek-r1:1.5b + +# 运行模型 +ollama run deepseek-r1:1.5b + +# 联网模型 +ollama pull nomic-embed-text +``` + +- 命令：`docker exec -it ollama /bin/bash` 也可以进入控制台 +- 首先，安装完成后，可以执行运行之后在后台进行对话。对话完成需要关闭的话，运行 Ctrl + D 关闭。 +- 之后，安装联网模型。这个过程要持续一会。另外不要一下就选很大的模型，怕你扛不住。 + +## 三、配置插件 + +官网：[https://github.com/n4ze3m/page-assist](https://github.com/n4ze3m/page-assist) + +### 1. 搜索安装 + +为了更方便的使用 DeepSeek 模型，这里可以在谷歌浏览器安装一个 Page Assist 插件。 + +
+ +
+ +- 点击安装 Page Assist 插件 + +### 2. 链接地址 + +
+ +
+ +### 3. 设置中文 + +
+ +
+ +### 4. 配置知识库 - RAG + +
+ +
+ +### 5. 添加知识库 - PDF/MD + +
+ +
+ +## 四、对话使用 + +### 1. ai对话 + +
+ +
+ +- 你可以选择模型、联网、图片识别和自己设定的知识库。 + +### 2. 页面对话 + +
+ +
+ +- 你可以在插件上右键，之后就可以与你需要的另外的网页进行对话。理解网页内容做解答。 + +## 五、API 对接 + +### 1. curl 接口 + +```java +curl http://192.168.1.109:11434/api/generate \ + -H "Content-Type: application/json" \ + -d '{ + "model": "deepseek-r1:1.5b", + "prompt": "1+1", + "stream": false + }' + +``` + +- 这是请求 Ollama DeepSeek 模型的 curl 操作。 + +### 2. 代码请求 + +#### 2.1 配置接口 + +```java +@Configuration +public class OllamaConfig { + + @Bean + public OllamaApi ollamaApi() { + Retrofit retrofit = new Retrofit.Builder() + .baseUrl("http://192.168.1.109:11434") + .addConverterFactory(JacksonConverterFactory.create()).build(); + + return retrofit.create(OllamaApi.class); + } + + public interface OllamaApi { + @POST("/api/generate") + Call generate(@Body OllamaRequest request); + } + + @Data + @AllArgsConstructor + @NoArgsConstructor + public static class OllamaRequest { + private String model; + private String prompt; + private boolean stream; + } + + // ... 省略部分代码 +} +``` + +- 这里我们使用 retrofit2 框架封装对模型API的访问。 + +#### 2.2 访问接口 + +```java +@Slf4j +@RunWith(SpringRunner.class) +@SpringBootTest +public class OllamaTest { + + @Resource + private OllamaConfig.OllamaApi api; + + @Test + public void test_chat() throws IOException { + OllamaConfig.OllamaRequest request = new OllamaConfig.OllamaRequest( + "deepseek-r1:1.5b", + "1+1", + false + ); + + Call generate = api.generate(request); + Response execute = generate.execute(); + OllamaConfig.OllamaResponse response = execute.body(); + + log.info("测试结果:{}", JSON.toJSONString(response.getResponse())); + } + +} +``` + +

+ +- 首先，关于安装可以使用 curl 向导式一次安装，也可以使用 npm 安装软件后，在启动配置向导。在 [xfg-dev-tech-docker-install](https://gitcode.com/Yao__Shun__Yu/xfg-dev-tech-docker-install) 一键安装脚本中，提供了 `sudo ./openclaw.sh` 安装脚本，附带的会帮助你完成 nodejs 22+ 的检测和安装，以及飞书组件的提示，会简化一些你的操作。 +- 然后，在执行 `sudo openclaw onboard` 运行向导后，会告诉你这个软件的安全提示，你可以通过`←` `→`选择 yes 安装即可。再往后，会进行模型的选择，这里支持好多模型，本案例使用的 [glm apikey](https://www.bigmodel.cn/glm-coding?ic=KFLKGANUMO) +- 之后，一系列选择后（不分可以跳过），包括通信渠道（飞书）也可以先跳过，即可完成安装。安装后可以通过 `sudo openclaw gateway` 启动网关。这样 openclaw 也就正式启动起来了。 +- 再后，安装飞书插件 `sudo openclaw plugins install @m1heng-clawd/feishu --registry https://registry.npmmirror.com` 这东西的目的是让 openclaw 可以对接上飞书。 + +### 2. 常用命令 + +| 命令 | 作用 | 备注 / 参数 | +| :----------------------------------------------------------- | :---------------------- | :-------------------------------------------- | +| `npm install -g openclaw@latest --registry https://registry.npmmirror.com` | 安装 openclaw | | +| `openclaw onboard` | 安装引导 | | +| `openclaw status` | 查看 Gateway 状态 | 检查网关是否可达及运行状况 | +| `openclaw health` | 健康检查 | 主要检测 core 运行和依赖情况 | +| `openclaw doctor` | 综合诊断与修复建议 | 可配合 `--yes` / `--non-interactive` 自动执行 | +| `openclaw configure` | 交互式配置向导 | 用于设置模型、通道、凭据等 | +| `openclaw config get ` | 获取配置值 | 指定路径提取配置 | +| `openclaw config set ` | 设置配置项 | 支持 JSON5/raw 文本 | +| `openclaw config unset ` | 清除配置项 | 移除单个键值 | +| `openclaw channels list` | 列出已登录通道 | 可观察 WhatsApp/Telegram 等登录状态 | +| `openclaw channels login` | 登录新的通道账号 | 用于扫描/授权链接 | +| `openclaw skills list` | 列出技能 | 查看可用/已安装的技能 | +| `openclaw skills info ` | 技能详情 | 观察某项技能参数或版本 | +| `openclaw plugins list` | 列出插件 | 查看已安装插件 | +| `openclaw plugins install ` | 安装插件 | 例如 @openclaw/voice-call | +| `openclaw plugins enable ` | 启用插件 | 之后通常需要重启网关 | +| `openclaw logs --follow` | 显示日志 | `--json / --plain / --limit` 等组合使用 | +| `openclaw gateway` | 启动 Gateway 网关 | | +| `openclaw gateway install` | 安装系统服务 | 根据平台注册 Gateway 守护进程 | +| `openclaw gateway start` | 启动 Gateway 网关 | 系统服务模式下启动 | +| `openclaw gateway stop` | 停止 Gateway 网关 | 同上 | +| `openclaw gateway restart` | 重启 Gateway 网关 | 适合配置变更后应用 | +| `openclaw gateway status` | 网关系统服务状态 | 不同于 `openclaw status`，会探测服务单元 | +| `openclaw uninstall` | 卸载 Gateway 服务及数据 | 官方推荐使用 | +| `openclaw uninstall --all --yes --non-interactive` | 全自动卸载 | 包含状态、workspace、插件等 | +| `openclaw uninstall --state` | 删除状态文件 | 不删除 workspace/CLI | +| `openclaw uninstall --workspace` | 删除工作区 | 移除 agent/workspace 文件 | +| `openclaw uninstall --service` | 仅卸载服务 | 不删除数据 | +| `openclaw uninstall --dry-run` | 模拟卸载 | 显示结果但不实际执行 | + +## 三、部署操作 + +### 1. 创建飞书 + +
+ +

+ +
+ +- 创建应用后，点击发布应用。这样你创建的应用才是有效的。 + +#### 1.3 事件配置（机器人）- openclaw 配置之前 + +
+ +
+ +- 飞书应用创建后，还需要配置机器人。但这会配置也是失败的，因为 openclaw 还没有关联上来。 +- 这里需要在 openclaw 配置飞书通信渠道，之后重启 openclaw 网关，这里点击保存并配置权限（`接收消息`、`通讯录基本信息`），点击确认开通权限。在发布一个新应用，再和飞书机器人对话就可以使用了。 + +### 2. 安装应用（openclaw） + +#### 2.1 执行脚本（含带引导） + +```java +curl -fsSL https://openclaw.ai/install.sh | sudo bash -s -- --registry https://registry.npmmirror.com +``` + +- openclaw 官网版 + +```java +curl -fsSL https://clawd.org.cn/install.sh | sudo bash -s -- --registry https://registry.npmmirror.com +``` + +- openclaw-cn 中文社区版，适合新人伙伴使用。熟练后，使用官网版即可。他们操作的方式是一样的。 +- 安装后的使用差异，一个是 `sudo openclaw config` 一个是 `sudo openclaw-cn config` + +#### 2.2 引导配置 + +```java +sudo npm install -g openclaw@latest --registry https://registry.npmmirror.com +sudo npm install -g openclaw-cn@latest --registry https://registry.npmmirror.com + +# 运行向导 +sudo openclaw onboard +sudo openclaw-cn onboard +``` + +- 注意 `-cn` 为中文版，如果你不是执行的 curl 一键安装版本，是采用了 安装 `openclaw@latest` 程序，那么需要自己执行引导配置。 + +##### 2.2.1 安全提示 + +
+ +
+ +##### 2.2.2 配置方式 + +
+ +
+ +##### 2.2.3 模型配置 + +
+ +
+ +
+ +
+ +##### 2.2.4 通信通道（飞书） + +**选择渠道** + +
+ +
+ +**安装插件** + +
+ +
+ +- 如果未安装过飞书插件，可以选择安装，也可以跳过后，后续在安装。 +- 单独安装插件 `sudo openclaw-cn plugins install @m1heng-clawd/feishu` + +**配置凭证** + +
+ +
+ +- 把你的应用凭证，配置到 openclaw 应用程序里。之后继续回车。 +- 注意，一会要会到飞书页面，配置事件关联到 openclaw 上。 + +##### 2.2.5 技能配置 + +
+ +
+ +##### 2.2.6 部署完成 + +
+ +
+ +
+ +
+ +```java +ubuntu@VM-0-2-ubuntu:~$ sudo openclaw-cn gateway +``` + +- 配置完成后，要启动下网关。能看到以上信息，表示运行没问题了。 +- 现在要到 3.1 接着配置飞书。 + +### 3. 配置飞书 + +#### 3.1 事件配置（机器人） + +
+ +
+ +- 注意，完成 2.2.6 步骤后，再回来操作。 +- openclaw 关联上飞书以后，点击**添加事件**，以及添加上相关权限。完成后，会提示你发布一个新应用。 + +#### 3.2 发布应用 + +
+ +
+ +- 点击发布应用，版本号 +1 + +#### 3.3 打开应用 + +
+ +
+ +- 这会对话飞书，会提示执行一个命令，类似于验证签名。 +- 命令 `sudo openclaw-cn pairing approve feishu KF2BRAXW` + +#### 3.4 验证前面（+重启网关） + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +本文的宗旨在于通过简单干净实践的方式教会读者，多种类型的任务执行组件使用案例，包括：Quartz 使用、扩展 Spring-Schedule 自动增加任务、XXL-Job 分布式任务调度。其中像 Spring-Schedule 小傅哥还添加了一些 Spring 组件开发的能力可自动扩展任务、对 XXL-Job 的配置引入了 Docker Compose 自动化安装和自动初始化 MySQL 数据库 xxl-job.sql 库表数据。这些都是为了让你在不同的场景选择合适的框架，同时也能更简单的使用这些框架。 + +本章节的任务调度组件会放到 DDD 的 Trigger 模块中，也就是触发器层。我们认为所有的调用行为，HTTP、RPC、MQ、任务，都是一个触发的入口，所以对于任务调度也放到这一层使用。 + +本文涉及的工程： + +- xfg-dev-tech-quartz：[https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-quartz](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-quartz) +- xxl-job-docker.compose.yml 安装：[xxl-job-docker.compose.yml](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-quartz/-/blob/master/docs/xxl-job/xxl-job-docker-compose.yml) - `xxl-job 已提供了最简化安装自动导入库表操作` + +## 一、案例背景 + +任务调度是一个非常重要的功能组件，常作用于：定时清理数据 - 冷数据迁移、活动状态扫描 - 过期活动关闭、消息发送补偿 - MQ失败重发、支付掉单补偿 - 支付幂等重试，等各类场景都会用到任务调度组件。它可以帮我们执行确定规则的业务或功能流程。 + +
+ +
+ +- 以整个 DDD 分层架构中，以触发器层为入口编写任务调度方法。任务的实现方式有多种，如果你的场景较为简单，则使用 Spring 或者 Quartz 提供的任务实现方式即可。如果你的场景较为复杂，需要分布式任务管理，那么最好配置一套如 XXL-Job 这样的分布式任务调度组件来使用。 +- 所有的触发器中的任务，都只是固定时间频次下的执行入口，最终需要调用领域层所提供的方法完成具体的业务逻辑。如果你使用 DDD 分层有 case/application 防腐处理，则会调用这一编排层，而不是 domain 领域层。 + +## 二、任务模型 + +当你的微服务应用是一组较小的模型结构时，其实任务与服务结合在一起即可，让它与自己的领域绑定。但如果微服务的体量很大，那么这组微服务所对应的任务也会较多，同时需要一些分布式的能力，让调度的算力可以更快更好的运用起来。 + +所以一般这个时候就需要引入把任务单独拆分出一个微服务系统，一般可以叫做 xxx-worker 系统，他们就是专门处理任务的一个个执行器。把这些执行器注册到任务调度中心，由任务调度中心统一管理各项任务的执行。这样如果有一个任务在一个算力执行器上失败或者说执行器宕机了，那么可以把任务迁移到其他算力执行器上执行。这就是分布式的好处。 + +
+ +
+ +- 如图，就是分布式架构下。执行器系统被任务调度中心管理，调用微服务提供的接口，完成对微服务接口的调用。 +- 一般分布式引用的微服务接口，也都是 RPC 接口，这样就已经具备了负载能力。 +- 任务调度与 MQ 消息是一组非常常用的技术栈组合，MQ 失败的消息，经常是由任务扫描补偿，继续发送MQ消息，驱动流程的执行。 + +## 三、环境安装 + +本案例所需安装的环境主要是 XXL-Job 的一套 MySQL 库和 XXL-Job 应用以及对应的库表初始化。为了让大家使用起来更加简单，小傅哥这里提供了一套 compose.yml 支持 AMD 和 ARM 架构使用。 + +
+ +
+ +- 在此位置找到执行文件，如果你本机已经安装过 [Docker](https://bugstack.cn/md/road-map/docker.html) 那么在 IntelliJ IDEA 中直接执行即可。 + +### 1. 执行 compose.yml + +文件：[docs/xxl-job/xxl-job-docker-compose.yml](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-quartz/-/blob/master/docs/xxl-job/xxl-job-docker-compose.yml) + +```yml +# 命令执行 docker-compose up -d +version: '3.9' +services: + # http://127.0.0.1:9090/xxl-job-admin admin/123456 - 安装后稍等会访问即可 + # 官网镜像为 xuxueli/xxl-job-admin 但不支持ARM架构【需要自己打包】，所以找了一个 kuschzzp/xxl-job-aarch64:2.4.0 镜像支持 AMD/ARM + xxl-job-admin: + image: kuschzzp/xxl-job-aarch64:2.4.0 + container_name: xxl-job-admin + restart: always + depends_on: + - mysql + ports: + - "9090:9090" + links: + - mysql + volumes: + - ./data/logs:/data/applogs + - ./data/xxl-job/:/xxl-job + environment: + - SPRING_DATASOURCE_URL=jdbc:mysql://mysql:3306/xxl_job?serverTimezone=UTC&characterEncoding=utf8&autoReconnect=true&serverTimezone=Asia/Shanghai + - SPRING_DATASOURCE_USERNAME=root + - SPRING_DATASOURCE_PASSWORD=123456 + - SERVER_PORT=9090 + + # MySQL 8.0.32 支持 AMD/ARM + mysql: + image: mysql:8.0.32 + container_name: mysql + command: --default-authentication-plugin=mysql_native_password + restart: always + environment: + TZ: Asia/Shanghai + # MYSQL_ALLOW_EMPTY_PASSWORD: 'yes' 可配置无密码，注意配置 SPRING_DATASOURCE_PASSWORD= + MYSQL_ROOT_PASSWORD: 123456 + MYSQL_USER: xfg + MYSQL_PASSWORD: 123456 + depends_on: + - mysql-job-dbdata + ports: + - "13306:3306" # 如果你无端口占用，可以直接使用 3306 + volumes: + - ./sql:/docker-entrypoint-initdb.d + volumes_from: + - mysql-job-dbdata + + # 自动加载数据 + mysql-job-dbdata: + image: alpine:3.18.2 + container_name: mysql-job-dbdata + volumes: + - /var/lib/mysql +``` + +
+ +
+ +- 在 IDEA 中打开 xxl-job-docker-compose.yml 你会看到一个绿色的按钮在左侧侧边栏，点击即可安装。或者你也可以使用命令安装：`# /usr/local/bin/docker-compose -f /docs/xxl-job/xxl-job-docker-compose.yml up -d` - 比较适合在云服务器上执行。 +- 在 compose 中提供了 xxl-job 所需要的库的依赖安装，以及自动加载文件下的初始化库表数据。这个库表数据来自于 xxl-job sql：[https://gitee.com/xuxueli0323/xxl-job/blob/master/doc/db/tables_xxl_job.sql](https://gitee.com/xuxueli0323/xxl-job/blob/master/doc/db/tables_xxl_job.sql) - `这里小傅哥把 SQL 文件下载到了本地，用于初始化安装使用` +- 标签：`depends_on` - 依赖于谁先安装、`MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'` - 可以设置MySQL无密码安装、`mysql-job-dbdata` - 一个启动安装数据库初始化脚本的镜像。并且需要在 MySQL 安装时使用 `volumes_from` 标签引入。 + +### 2. 访问 xxl-job + +**地址**：[http://127.0.0.1:9090/xxl-job-admin](http://127.0.0.1:9090/xxl-job-admin) - admin/123456 - 安装后稍等启动完成，就可以访问啦。 + +
+ +
+ +- 默认的账号 admin 密码 123456 + +### 3. 执行器管理 + +执行器的作用，就是让 xxl-job-admin 这个任务调度系统，调用注册上来的执行器完成任务的执行。客户端需要配置好这里的执行器名称才能注册上来。你可以根据自己的需要新增新的执行器，也可以在测试的时候使用默认的这个执行器名称。 + +
+ +
+ +- 本地服务启动后，会注册进来一个执行器的地址，OnLine 机器地址会显示。 + +### 4. 任务配置 + +任务的作用，就是执行器下具体的执行方法，按照配置的时间下发到任务中执行。 + +```java +@Slf4j +@Component +public class XXLJob { + + @XxlJob("demoJobHandler") + public void doJob() { + // 可以在任务中，调用一些业务方法逻辑的实现，如定时扫描超时未支付订单为关单处理，恢复库存 + log.info("执行任务 - XXL-Job - 01"); + } + +} +``` + +
+ +
+ +- 一个执行器下管理的任务一般会有很多，所以你在测试的时候也可以尝试新增一些任务来测试。 + +## 四、工程实现 + +### 1. 工程结构 + +
+ +
+ +- 首先，trigger 触发器模块下有3类任务，分别是 Quartz、Schedule 和 XXL-Job 分布式任务。XXL-Job 所需的配置会多一些，需要 application-dev.yml 配置 xxl-job 参数，之后配置 Config 启动任务。最后是 XXL-Job 使用任务。 +- QuartzJob 就是一个直接使用的案例，但像 XXL-Job 也是基于 Quartz 扩展的，小傅哥也做了一个分布式任务调度的中间件，如果感兴趣也可以学习。[https://bugstack.cn/md/assembly/middleware/%E7%AC%AC%2015%20%E7%AB%A0%20%E5%88%86%E5%B8%83%E5%BC%8F%E4%BB%BB%E5%8A%A1%E8%B0%83%E5%BA%A6.html](https://bugstack.cn/md/assembly/middleware/%E7%AC%AC%2015%20%E7%AB%A0%20%E5%88%86%E5%B8%83%E5%BC%8F%E4%BB%BB%E5%8A%A1%E8%B0%83%E5%BA%A6.html) +- ScheduleJob 是基于 Spring 提供的 Schedule 进行的扩展，可以根据自定义注解添加任务和自动启动。这个方式也是非常好用的。 + +### 2. 配置文件 + +**引入POM** + +```pom + + + org.quartz-scheduler + quartz + 2.3.2 + + + + + org.springframework.boot + spring-boot-starter-quartz + 3.1.2 + + + + + com.xuxueli + xxl-job-core + 2.4.0 + +``` + +- 分别包括：Quartz、XXL-Job 两个组件 + +**添加配置** + +```yml +# xxl-job https://www.xuxueli.com/xxl-job/#%E6%AD%A5%E9%AA%A4%E4%B8%80%EF%BC%9A%E8%B0%83%E5%BA%A6%E4%B8%AD%E5%BF%83%E9%85%8D%E7%BD%AE%EF%BC%9A +xxl: + job: + # 验证信息 官网Bug https://github.com/xuxueli/xxl-job/issues/1951 + accessToken: default_token + # 注册地址 + admin: + addresses: http://localhost:9090/xxl-job-admin + # 注册执行器 + executor: + # 执行器注册 [选填]：优先使用该配置作为注册地址，为空时使用内嵌服务 ”IP:PORT“ 作为注册地址。从而更灵活的支持容器类型执行器动态IP和动态映射端口问题。 + address: + appname: xxl-job-executor-sample + # 执行器IP 配置为本机IP [选填]：默认为空表示自动获取IP，多网卡时可手动设置指定IP，该IP不会绑定Host仅作为通讯实用；地址信息用于 "执行器注册" 和 "调度中心请求并触发任务"； + ip: + # 执行器端口号 [选填]：小于等于0则自动获取；默认端口为9999，单机部署多个执行器时，注意要配置不同执行器端口； + port: 9999 + # 执行器运行日志文件存储磁盘路径 [选填] ：需要对该路径拥有读写权限；为空则使用默认路径； + logpath: ./data/applogs/xxl-job/jobhandler + # 执行器日志文件保存天数 [选填] ： 过期日志自动清理, 限制值大于等于3时生效; 否则, 如-1, 关闭自动清理功能； + logretentiondays: 30 +``` + +xxl-job 有一些必要的配置信息 +- accessToken，默认是一个 default_token - 它的官网也有 issue 提到这个bug，如果未配置，应该为空。[https://github.com/xuxueli/xxl-job/issues/1951](https://github.com/xuxueli/xxl-job/issues/1951) +- addresses，是一个注册地址，也就是我们访问 xxl-job 的地址 +- appname，我们这里使用了官网默认提供的执行器的名称 xxl-job-executor-sample 你可以新增或者修改。 +- ip、port 意思是你把本地的执行器注册到调度中心，如果你的 XXL-Job 部署到云服务器，而本地启动服务的时候，你是可以注册到服务端的，但调度中心没法调用到你本地的服务，因为你本地没有公网IP。这个时候你可以使用 natapp 做映射内网穿透进行测试。 + +### 3. 任务配置 + +#### 3.1 Quartz 任务 + +**源码**：`cn.bugstack.xfg.dev.tech.job.QuartzJob` + +```java +@Slf4j +@Component() +public class QuartzJob { + + @Scheduled(cron = "0/3 * * * * ?") + public void execute01() { + // 可以在任务中，调用一些业务方法逻辑的实现，如定时扫描超时未支付订单为关单处理，恢复库存 + log.info("执行任务 - Quartz - 01"); + } + + @Scheduled(cron = "0/3 * * * * ?") + public void execute02() { + // 可以在任务中，调用一些业务方法逻辑的实现，如定时扫描超时未支付订单为关单处理，恢复库存 + log.info("执行任务 - Quartz - 02"); + } + +} +``` + +- Quartz 支持在一个类中，配置多个任务，每个任务方法都可以配置自己执行策略。 +- 此类方式非常适合一些不需要统一任务调度的简单场景使用。 + +#### 3.2 Spring-Schedule 扩展任务 + +**配置任务注册器** - 在 app config 下 + +```java +@Slf4j +@Configuration +@EnableScheduling +public class JobRegistrarAutoConfig implements SchedulingConfigurer { + + private final ApplicationContext applicationContext; + + public JobRegistrarAutoConfig(ApplicationContext applicationContext) { + this.applicationContext = applicationContext; + } + + @Override + public void configureTasks(ScheduledTaskRegistrar taskRegistrar) { + Map jobBeanMap = applicationContext.getBeansOfType(ExtScheduleJob.class); + Collection jobBeans = jobBeanMap.values(); + for (ExtScheduleJob job : jobBeans) { + ExtScheduleJobConfig extScheduleJobConfig = AnnotationUtils.findAnnotation(job.getClass(), ExtScheduleJobConfig.class); + if (extScheduleJobConfig == null || !extScheduleJobConfig.state()) continue; + + log.info("启动任务 {} {}", extScheduleJobConfig.jobName(), extScheduleJobConfig.cronExpression()); + taskRegistrar.addCronTask(job, extScheduleJobConfig.cronExpression()); + } + } + +} +``` + +- JobRegistrarAutoConfig 实现了 SchedulingConfigurer 的类，可以自己自动化的根据所有实现了 ExtScheduleJob 类进行任务扩展添加。 +- 这是一种扩展方式，有了这样的扩展方式，如果你是做同类的任务需求，只是配置不同的话，那么还可以基于 yml 配置，来创建出不同的代理任务。 + +#### 3.3 XXL-Job + +**源码**：`cn.bugstack.xfg.dev.tech.job.XXLJob` + +```java +@Slf4j +@Component +public class XXLJob { + + @XxlJob("demoJobHandler") + public void doJob() { + // 可以在任务中，调用一些业务方法逻辑的实现，如定时扫描超时未支付订单为关单处理，恢复库存 + log.info("执行任务 - XXL-Job - 01"); + } + +} +``` + +

+ +
+ +- 这是一套 DDD 工程模型，也可以说整个教程其实都是 DDD 工程模型的拆解讲解，将各个模块嵌入到 DDD 分层架构中，看看他们是如何使用的。 +- 工程分为，app、domain、infrastructure、trigger 这样的四层，其实还有一个 types 通用层。 + + - app；用于配置 Redis 的相关启动操作，鉴于 SpringBoot 以及 Redis 版本问题，这里我们自己来创建客户端，更好兼容版本的差异。同时也可以扩展一些额外的功能。 + - domain；是领域服务层，order 可以看做是一个订单域，包括订单的创建、支付、查询，都可以在这个领域实现。*这个订单领域涉及的表就是前面章节，所压测的表 [【压测】MySQL 连接池 c3p0、dbcp、druid、hikari](https://bugstack.cn/md/road-map/connection-pool.html)* + - infrastructure；基础层是对 domain 依赖倒置的实现，具体到库的操作、缓存的操作，都是用这一层来实现。所以我们操作 Redis 的加锁、缓存，也会放到这里来处理。 + - trigger；触发器层，一般也有叫接口层。一般 http、rpc、job、mq、listener 都是在这一层进来使用。所以我们订阅 Redis 的消息也是放到这一层中处理。 + - types；工程中还有一个通用类型层，定义一些非专属 domain 领域内的公共资源。如配置一个自定义注解，来处理一些类的动态加载和组件开发。本章中我们就定义了一个这样的注解，来动态注入实例化的 Bean 对象。**这块非常值得学习一下，因为它是解决此类场景的高级编码** + +### 2. 配置缓存 + +在 app 模块下的 config 中，创建 RedisClientConfigProperties 配置类和 RedisClientConfig 客户端启动类。用于通过 Redisson 创建 Redis 的连接客户端。 + +```yml +redis: + sdk: + config: + host: localhost + port: 6379 + password: 123456 + pool-size: 10 + min-idle-size: 5 + idle-timeout: 30000 + connect-timeout: 5000 + retry-attempts: 3 + retry-interval: 1000 + ping-interval: 60000 + keep-alive: true +``` + +- 本身 Spring 也提供了 Redis 的配置，但鉴于兼容问题和后续的功能拓展，还是比较建议自己添加配置。 +- 关于代码的实现部分，可以参考 RedisClientConfigProperties、RedisClientConfig + +### 3. 数据缓存 + +Redis 的大部分操作其实都是缓存数据，提高系统的 QPS，在插入、更新、删除(逻辑删)、查询的时候，依赖于 Redis 进行提速操作。 + +
+ +
+ +```java +// 设置到缓存，在创建订单完成后写入缓存 +redissonService.setValue(orderId, orderEntity); + +@Override +public OrderEntity queryOrder(String orderId) { + OrderEntity orderEntity = redissonService.getValue(orderId); + if (null == orderEntity) { + UserOrderPO userOrderPO = userOrderDao.selectByOrderId(orderId); + orderEntity = new OrderEntity(); + orderEntity.setUserName(userOrderPO.getUserName()); + orderEntity.setUserId(userOrderPO.getUserId()); + // 设置到缓存 + redissonService.setValue(orderId, orderEntity); + } + return orderEntity; +} +``` + +- 在插入数据的时候，可以一并切入缓存。如果有更新操作，可以考虑删除缓存，在查询更新。因为更新操作，很多时候都是部分字段更新，这个时候直接更新缓存容易不准。 +- 最后就是查询时，用缓存拦截，避免所有的查询都打到库上。这样可以提高系统的 QPS +- 另外关于缓存击穿，说的就是你本来要在缓存存放大量数据的，但存放偏差或者漏了，那么这个时候大量请求都打到库上，导致把数据库拖垮。尤其是那种需要做事务加锁有资源竞争的，会更严重。 + +### 4. 加锁处理 + +使用 Redis 加分布式锁，也是分布式架构设计中非常常用的手段。常用于的场景包括；流程较长，耗时较多的个人开户、下单行为。也包括；一些资源竞争时加分布式锁，排队处理请求。但对于资源竞争的这类库存占用，如果加分布式锁是非常影响系统的吞吐量的，因为所有的用户都在等待上一个用户做完流程后释放锁的处理，相当于你即使系统是分布式的了，但这里的分布式锁依然会把性能拖慢。所以如图，我们要考虑两种场景不同的加锁方式。 + +
+ +
+ +```java +/** 独占锁 */ +@Override +public String createOrderByLock(OrderAggregate orderAggregate) { + RLock lock = redissonService.getLock("create_order_lock_".concat(orderAggregate.getSkuEntity().getSku())); + try { + lock.lock(); + long decrCount = redissonService.decr(orderAggregate.getSkuEntity().getSku()); + if (decrCount < 0) return "已无库存[初始化的库存和使用库存，保持一致。orderService.initSkuCount(\"13811216\", 10000);]"; + return createOrder(orderAggregate); + } finally { + lock.unlock(); + } +} + +/** 分段锁，也可以称为无锁化 */ +@Override +public String createOrderByNoLock(OrderAggregate orderAggregate) { + UserEntity userEntity = orderAggregate.getUserEntity(); + SKUEntity skuEntity = orderAggregate.getSkuEntity(); + // 模拟锁商品库存 + long decrCount = redissonService.decr(skuEntity.getSku()); + if (decrCount < 0) return "已无库存[初始化的库存和使用库存，保持一致。orderService.initSkuCount(\"13811216\", 10000);]"; + String lockKey = skuEntity.getSku().concat("_").concat(String.valueOf(decrCount)); + RLock lock = redissonService.getLock(lockKey); + try { + lock.lock(); + return createOrder(orderAggregate); + } finally { + lock.unlock(); + } +} +``` + +- 对于第1类的场景，主要是为了避免用户在一次操作后，又反复申请。系统上避免重复受理，所以添加分布式锁的方式进行拦截。如果不加分布式锁，就会进入到库表中通过唯一的索引拦截，这样对数据库的压力就比较大。 +- 对于第2类的场景，是采用了分段或者自增滑块的锁方式进行处理，减少对同一个锁的等待，而是生成一堆的锁，让用户去使用。**也就是最开始案例背景的图中，一个个⭕️圆圈的分段锁** + +### 5. 发布/订阅 + +此场景的案例会涉及到如何向 Spring 动态注入已经实例化后的 Bean 对象。为什么会出现这个场景呢？ + +首先 Redis 的发布订阅，简单案例代码如下； + +```java +// 创建Redisson客户端 +RedissonClient redisson = Redisson.create(); + +// 获取RTopic对象 +RTopic topic = redisson.getTopic("myTopic"); + +// 发布消息 +topic.publish("Hello, Redisson!"); + +// 添加监听器 +topic.addListener(String.class, (channel, msg) -> { + System.out.println("Received message: " + msg); +}); + +// 关闭Redisson客户端 +redisson.shutdown(); +``` + +- 发布和订阅，是我们需要对同一个 Topic 进行发布和监听操作。但这个操作的代码是一种手动编码，但在我们实际使用中，如果所有的都是手动编码，**一个是非常麻烦，再有一个是非常累人**。 +- 所以这里小傅哥决定给你来个高级编码，通过自定义注解，来完成动态监听和将对象动态注入到 Spring 容器中，让需要注入的属性，可以被动态注入。 + +#### 5.1 自定义注解 + +```java +@Retention(RetentionPolicy.RUNTIME) +@Target({ElementType.TYPE}) +@Documented +public @interface RedisTopic { + + String topic() default ""; + +} +``` + +- 起到了一种标识作用。`快捷键；你可以在 IDEA 工程中，摁2下 Shift 搜索这个类。` + +#### 5.2 注解使用 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.trigger.mq#RedisTopicListener02` + +```java +@Slf4j +@Service +@RedisTopic(topic = "testRedisTopic02") +public class RedisTopicListener02 implements MessageListener { + + @Override + public void onMessage(CharSequence channel, String msg) { + log.info("02-监听消息(Redis 发布/订阅): {}", msg); + } + +} +``` + +- 对需要监听 RedisTopic 的类，进行注解配置。之后在下面的代码中使用。 + +#### 5.3 动态注入 + +**源码**：`cn.bugstack.xfg.dev.tech.config.RedisClientConfig#redissonClient` + +```java +// 添加监听 +String[] beanNamesForType = applicationContext.getBeanNamesForType(MessageListener.class); +for (String beanName : beanNamesForType) { + MessageListener bean = applicationContext.getBean(beanName, MessageListener.class); + Class beanClass = bean.getClass(); + if (beanClass.isAnnotationPresent(RedisTopic.class)) { + RedisTopic redisTopic = beanClass.getAnnotation(RedisTopic.class); + + RTopic topic = redissonClient.getTopic(redisTopic.topic()); + topic.addListener(String.class, bean); + + // 动态创建 bean 对象，注入到 spring 容器，bean 的名称为 redisTopic，对象为 RTopic + ConfigurableListableBeanFactory beanFactory = applicationContext.getBeanFactory(); + beanFactory.registerSingleton(redisTopic.topic(), topic); + } +} +``` + +- 通过 applicationContext 获取所有实现了 MessageListener 接口的类，并对这个类的注解进行识别。 +- 所有使用了咱们定义注解的类，都进行获取获取 Topic 和添加监听操作。获取的 bean 对象，就是要监听的类。 +- 最后一步，再把这个类，通过 Spring 的 BeanFactory 工厂，进行注册。这样你再其他类中，就可以自动注入 topic 对象了，并进行 push 消息操作。 + +#### 5.4 使用对象 + +```java + +@Slf4j +@Repository +public class OrderRepository implements IOrderRepository { + + @Resource + private IRedisService redissonService; + @Resource + private IUserOrderDao userOrderDao; + + @Resource + private RTopic testRedisTopic; + + @Resource(name = "testRedisTopic02") + private RTopic testRedisTopic02; + + @Resource(name = "testRedisTopic03") + private RTopic testRedisTopic03; + + + @Override + public String createOrder(OrderAggregate orderAggregate) { + + // 省略... + + testRedisTopic02.publish(JSON.toJSONString(orderEntity)); + testRedisTopic03.publish(JSON.toJSONString(orderEntity)); + + return orderId; + } +} +``` + +- testRedisTopic 是我们硬编码创建的 Bean 对象，testRedisTopic02、testRedisTopic03 是我们通过自定义注解动态创建的 Bean 对象。 +- 之后就可以在需要 push 消息的方法中，使用 publish 发布你的消息内容了，并可以在监听中获取到消息。 + +## 四、功能测试 + +### 1. 分布式锁压测 + +**源码**：`cn.bugstack.xfg.dev.tech.test.domain.OrderServiceTest` + +```java +@Test +public void test_createOrder() throws InterruptedException { + String sku = RandomStringUtils.randomNumeric(9);

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +本文的宗旨在于通过简单干净实践的方式教会读者，使用 Docker 配置 RocketMQ 并在基于 DDD 分层结构的 SpringBoot 工程中使用 RocketMQ 技术。因为大部分 MQ 的发送都是基于特定业务场景的，所以本章节也是基于 [《MyBatis 使用教程和插件开发》](https://bugstack.cn/md/road-map/mybatis.html) 章节的扩展。 + +本章也会包括关于 MQ 消息的发送和接收应该处于 DDD 的哪一层的实践讲解和使用。 + +本文涉及的工程： + +- xfg-dev-tech-rocketmq：[https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-rocketmq](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-rocketmq) +- RocketMQ Docker 安装：[rocketmq-docker-compose-mac-amd-arm.yml](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-rocketmq/-/blob/master/docs/rocketmq/rocketmq-docker-compose-mac-amd-arm.yml) +- 导入测试库表 [road-map.sql](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-rocketmq/-/blob/master/docs/mysql/road-map.sql) + +## 一、案例背景 + +首先我们要知道，MQ 消息的作用是用于：`解耦过长的业务流程`和`应对流量冲击的消峰`。如：用户下单支付完成后，拿到支付消息推动后续的发货流程。也可以是我们基于 [《MyBatis 使用教程和插件开发》](https://bugstack.cn/md/road-map/mybatis.html) 中的案例场景，给雇员提升级别和薪资的时候，也发送一条MQ消息，用于发送邮件通知给用户。 + +
+ +
+ +- 从薪资调整到邮件发送，这里是2个业务流程，通过 MQ 消息的方式进行连接。 +- 其实MQ消息的使用场景特别多，原来你可能使用多线程的一些操作，现在就扩展为多实例的操作了。发送 MQ 消息出来，让应用的各个实例接收并进行消费。 + +## 二、领域事件 + +因为我们本章所讲解的内容是把 RocketMQ 放入 DDD 架构中进行使用，那么也就引申出领域事件定义。所以我们先来了解下，什么是领域事件。 + +领域事件，可以说是解耦微服务设计的关键。领域事件也是领域模型中非常重要的一部分内容，用于标示当前领域模型中发生的事件行为。一个领域事件会推进业务流程的进一步操作，在实现业务解耦的同时，也推动了整个业务的闭环。 + +
+ +
+ +- 首先，我们需要在领域模型层，添加一块 event 区域。它的存在是为了定义出在当前领域下所需的事件消息信息。信息的类型可以是model 下的实体对象、聚合对象。 +- 之后，消息的发送是放在基础设置层。本身基础设置层就是依赖倒置于模型层，所以在模型层所定义的 event 对象，可以很方便的在基础设置层使用。而且大部分开发的时候，MQ消息的发送与数据库操作都是关联的，采用的方式是，做完数据落库后，推送MQ消息。所以定义在仓储中实现，会更加得心应手、水到渠成。 +- 最后，就是 MQ 的消费，MQ 的消费可以是自身服务所发出的消息，也可以是外部其他微服务的消息。就在小傅哥所整体讲述的这套简明教程中 DDD 部分的触发器层。 + +## 三、环境安装 + +本案例涉及了数据库和RocketMQ的使用，都已经在工程中提供了安装脚本，可以按需执行。 + +
+ +
+ +这里主要介绍 RocketMQ 的安装： + +### 1. 执行 compose yml + +**文件**：[docs/rocketmq/rocketmq-docker-compose-mac-amd-arm.yml](https://gitcode.net/KnowledgePlanet/road-map/xfg-dev-tech-rocketmq/-/blob/master/docs/rocketmq/rocketmq-docker-compose-mac-amd-arm.yml) - 关于安装小傅哥提供了不同的镜像，包括Mac、Mac M1、Windows 可以按需选择使用。 + +```yml +version: '3' +services: + # https://hub.docker.com/r/xuchengen/rocketmq + # 注意修改项： + # 01：data/rocketmq/conf/broker.conf 添加 brokerIP1=127.0.0.1 + # 02：data/console/config/application.properties server.port=9009 - 如果8080端口被占用，可以修改或者添加映射端口 + rocketmq: + image: livinphp/rocketmq:5.1.3 + container_name: rocketmq + ports: + - 9009:9009 + - 9876:9876 + - 10909:10909 + - 10911:10911 + - 10912:10912 + volumes: + - ./data:/home/app/data + environment: + TZ: "Asia/Shanghai" + NAMESRV_ADDR: "rocketmq:9876" +``` + +- 在 IDEA 中打开 rocketmq-docker-compose-mac-amd-arm.yml 你会看到一个绿色的按钮在左侧侧边栏，点击即可安装。或者你也可以使用命令安装：`# /usr/local/bin/docker-compose -f /docs/dev-ops/environment/environment-docker-compose.yml up -d` - 比较适合在云服务器上执行。 +- 首次安装可能使用不了，一个原因是 brokerIP1 未配置IP，另外一个是默认的 8080 端口占用。可以按照如下小傅哥说的方式修改。 + +### 2. 修改默认配置 + +1. 打开 `data/rocketmq/conf/broker.conf` 添加一条 `brokerIP1=127.0.0.1` 在结尾 + +```java +# 集群名称 +brokerClusterName = DefaultCluster +# BROKER 名称 +brokerName = broker-a +# 0 表示 Master, > 0 表示 Slave +brokerId = 0 +# 删除文件时间点，默认凌晨 4 点 +deleteWhen = 04 +# 文件保留时间，默认 48 小时 +fileReservedTime = 48 +# BROKER 角色 ASYNC_MASTER为异步主节点，SYNC_MASTER为同步主节点，SLAVE为从节点 +brokerRole = ASYNC_MASTER +# 刷新数据到磁盘的方式，ASYNC_FLUSH 刷新 +flushDiskType = ASYNC_FLUSH +# 存储路径 +storePathRootDir = /home/app/data/rocketmq/store +# IP地址 +brokerIP1 = 127.0.0.1 +``` + +2. 打开 ``data/console/config/application.properties` 修改 `server.port=9009` 端口。 + +```java +server.address=0.0.0.0 +server.port=9009 +``` + +- 修改配置后，重启服务。 + +### 3. RockMQ登录与配置 + +#### 3.1 登录 + +RocketMQ 此镜像，会在安装后在控制台打印登录账号信息，你可以查看使用。 + +
+ +
+ +
+ +
+ +登录：[http://localhost:9009/](http://localhost:9009/) + +#### 3.2 创建Topic + +
+ +
+ +- 也可以使用命令创建：`docker exec -it rocketmq sh /home/app/rocketmq/bin/mqadmin updateTopic -n localhost:9876 -c DefaultCluster -t xfg-mq` + +#### 3.3 创建消费者组 + +
+ +
+ +- 也可以使用命令创建：`docker exec -it rocketmq sh /home/app/rocketmq/bin/mqadmin updateSubGroup -n localhost:9876 -c DefaultCluster -g xfg-group` + +## 四、工程实现 + +### 1. 工程结构 + +
+ +
+ +- MQ 的使用无论是 RocketMQ 还是 Kafka 等，都很简单。但在使用之前，要考虑好怎么在架构中合理的使用。如果最初没有定义好这些，那么胡乱的任何地方都能发送和接收MQ，最后的工程将非常难以维护。 +- 所以这里整个MQ的生产和消费，是按照整个 DDD 领域事件结构进行设计。分为在 domain 使用基础层生产消息，再由 trigger 层接收消息。 + +### 2. 配置文件 + +**引入POM** + +```xml + + + org.apache.rocketmq + rocketmq-client-java + 5.0.4 + + + org.apache.rocketmq + rocketmq-spring-boot-starter + 2.2.0 + +``` + +**添加配置** + +```yml +# RocketMQ 配置 +rocketmq: + name-server: 127.0.0.1:9876 + consumer: + group: xfg-group + # 一次拉取消息最大值，注意是拉取消息的最大值而非消费最大值 + pull-batch-size: 10 + producer: + # 发送同一类消息的设置为同一个group，保证唯一 + group: xfg-group + # 发送消息超时时间，默认3000 + sendMessageTimeout: 10000 + # 发送消息失败重试次数，默认2 + retryTimesWhenSendFailed: 2 + # 异步消息重试次数，默认2 + retryTimesWhenSendAsyncFailed: 2 + # 消息最大长度，默认1024 * 1024 * 4(默认4M) + maxMessageSize: 4096 + # 压缩消息阈值，默认4k(1024 * 4) + compressMessageBodyThreshold: 4096 + # 是否在内部发送失败时重试另一个broker，默认false + retryNextServer: false +``` + +### 3. 定义领域事件 + +**源码**：`cn.bugstack.xfg.dev.tech.domain.salary.event.SalaryAdjustEvent` + +
+ +
+ +```java +@EqualsAndHashCode(callSuper = true) +@Data +public class SalaryAdjustEvent extends BaseEvent { + + public static String TOPIC = "xfg-mq"; + + public static SalaryAdjustEvent create(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate) { + SalaryAdjustEvent event = new SalaryAdjustEvent(); + event.setId(RandomStringUtils.randomNumeric(11)); + event.setTimestamp(new Date()); + event.setData(adjustSalaryApplyOrderAggregate); + return event; + } + +} +``` + +- 每个领域的消息，都有领域自己定义。发送的时候再交给基础设施层来发送。 + +### 4. 消息发送 + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.event.EventPublisher` + +
+ +
+ +```java +@Component +@Slf4j +public class EventPublisher { + + @Setter(onMethod_ = @Autowired) + private RocketMQTemplate rocketmqTemplate; + + /** + * 普通消息 + * + * @param topic 主题 + * @param message 消息 + */ + public void publish(String topic, BaseEvent message) { + try { + String mqMessage = JSON.toJSONString(message); + log.info("发送MQ消息 topic:{} message:{}", topic, mqMessage); + rocketmqTemplate.convertAndSend(topic, mqMessage); + } catch (Exception e) { + log.error("发送MQ消息失败 topic:{} message:{}", topic, JSON.toJSONString(message), e); + // 大部分MQ发送失败后，会需要任务补偿 + } + } + + /** + * 延迟消息 + * + * @param topic 主题 + * @param message 消息 + * @param delayTimeLevel 延迟时长 + */ + public void publishDelivery(String topic, BaseEvent message, int delayTimeLevel) { + try { + String mqMessage = JSON.toJSONString(message); + log.info("发送MQ延迟消息 topic:{} message:{}", topic, mqMessage); + rocketmqTemplate.syncSend(topic, MessageBuilder.withPayload(message).build(), 1000, delayTimeLevel); + } catch (Exception e) { + log.error("发送MQ延迟消息失败 topic:{} message:{}", topic, JSON.toJSONString(message), e); + // 大部分MQ发送失败后，会需要任务补偿 + } + } + +} +``` + +- 在基础设施层提供 event 事件的处理，也就是 MQ 消息的发送。 + + +**源码**：`cn.bugstack.xfg.dev.tech.infrastructure.repository.SalaryAdjustRepository` + +```java +@Resource +private EventPublisher eventPublisher; + +@Override +@Transactional(rollbackFor = Exception.class, timeout = 350, propagation = Propagation.REQUIRED, isolation = Isolation.DEFAULT) +public String adjustSalary(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate) { + + // ... 省略部分代码 + + eventPublisher.publish(SalaryAdjustEvent.TOPIC, SalaryAdjustEvent.create(adjustSalaryApplyOrderAggregate)); + return orderId; +} +``` + +在 SalaryAdjustRepository 仓储的实现中，做完业务流程开始发送 MQ 消息。这里有2点要注意： +1. 消息发送，不要写在数据库事务中。因为事务一直占用数据库连接，需要快速释放。 +2. 对于一些强MQ要求的场景，需要在发送MQ前，写入一条数据库 Task 记录，发送消息后更新 Task 状态为成功。如果长时间未更新数据库状态或者为失败的，则需要由任务补偿进行处理。 + +### 5. 消费消息 + +**源码**：`cn.bugstack.xfg.dev.tech.trigger.mq.SalaryAdjustMQListener` + +
+ +
+ +```java +@Component +@Slf4j +@RocketMQMessageListener(topic = "xfg-mq", consumerGroup = "xfg-group") +public class SalaryAdjustMQListener implements RocketMQListener { + + @Override + public void onMessage(String s) { + log.info("接收到MQ消息 {}", s); + } + +} +``` + +- 消费消息，配置消费者组合消费的主题，之后就可以接收到消息了。接收以后你可以做自己的业务，如果抛出异常，消息会进行重新接收处理。 + +## 六、测试验证 + +### 1. 单独发送消息测试 + +```java +@Slf4j +@RunWith(SpringRunner.class) +@SpringBootTest +public class RocketMQTest { + + @Setter(onMethod_ = @Autowired) + private RocketMQTemplate rocketmqTemplate; + + @Test + public void test() throws InterruptedException { + while (true) { + rocketmqTemplate.convertAndSend("xfg-mq", "我是测试消息"); + Thread.sleep(3000); + } + } + +} +``` + +- 这里方便你来发送消息，验证流程。 + +### 2. 业务流程消息验证 + +```java +@Test +public void test_execSalaryAdjust() throws InterruptedException { + AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate = AdjustSalaryApplyOrderAggregate.builder() + .employeeNumber("10000001") + .orderId("100908977676003") + .employeeEntity(EmployeeEntity.builder().employeeLevel(EmployeePostVO.T3).employeeTitle(EmployeePostVO.T3).build()) + .employeeSalaryAdjustEntity(EmployeeSalaryAdjustEntity.builder() + .adjustTotalAmount(new BigDecimal(100)) + .adjustBaseAmount(new BigDecimal(80)) + .adjustMeritAmount(new BigDecimal(20)).build()) + .build(); + String orderId = salaryAdjustApplyService.execSalaryAdjust(adjustSalaryApplyOrderAggregate); + log.info("调薪测试 req: {} res: {}", JSON.toJSONString(adjustSalaryApplyOrderAggregate), orderId); + Thread.sleep(Integer.MAX_VALUE); +} +``` + +```java +23-07-29.15:40:52.307 [main ] INFO HikariDataSource - HikariPool-1 - Start completed. +23-07-29.15:40:52.445 [main ] INFO EventPublisher - 发送MQ消息 topic:xfg-mq message:{"data":{"employeeEntity":{"employeeLevel":"T3","employeeTitle":"T3"},"employeeNumber":"10000001","employeeSalaryAdjustEntity":{"adjustBaseAmount":80,"adjustMeritAmount":20,"adjustTotalAmount":100},"orderId":"100908977676004"},"id":"98117654515","timestamp":"2023-07-29 15:40:52.425"} +23-07-29.15:40:52.517 [main ] INFO ISalaryAdjustApplyServiceTest - 调薪测试 req: {"employeeEntity":{"employeeLevel":"T3","employeeTitle":"T3"},"employeeNumber":"10000001","employeeSalaryAdjustEntity":{"adjustBaseAmount":80,"adjustMeritAmount":20,"adjustTotalAmount":100},"orderId":"100908977676004"} res: 100908977676004 +23-07-29.15:40:52.520 [ConsumeMessageThread_1] INFO SalaryAdjustMQListener - 接收到MQ消息 {"data":{"employeeEntity":{"employeeLevel":"T3","employeeTitle":"T3"},"employeeNumber":"10000001","employeeSalaryAdjustEntity":{"adjustBaseAmount":80,"adjustMeritAmount":20,"adjustTotalAmount":100},"orderId":"100908977676004"},"id":"98117654515","timestamp":"2023-07-29 15:40:52.425"} +``` + +- 当执行一次加薪调整后，就会接收到MQ消息了。 diff --git a/docs/md/road-map/sharding-jdbc.md b/docs/md/road-map/sharding-jdbc.md new file mode 100644 index 000000000..d9460f692 --- /dev/null +++ b/docs/md/road-map/sharding-jdbc.md @@ -0,0 +1,234 @@ +--- +title: sharding-jdbc +lock: need +--- + +# sharding-jdbc 使用教程和模型结构 + +作者：小傅哥 +

+ } +} +``` + +- **场景**：IAwardService 接口有多个实现类，可以通过 @Resource、@Autowired 注解注入，也可以通过构造函数注入。在 Spring 官网文档中，是推荐使用构造函数注入的：`The Spring team generally advocates constructor injection, as it lets you implement application components as immutable objects and ensures that required dependencies are not null.` [https://docs.spring.io/spring-framework/reference/core/beans/dependencies/factory-collaborators.html](https://docs.spring.io/spring-framework/reference/core/beans/dependencies/factory-collaborators.html) +- **用途**：Map 注入是一个非常好的注入手段，我们可以把每个 IAwardService 实现类设定好 Bean 的名称为数据库中的奖品 awardKey。在发奖的时候，可以直接根据 awardKey 从 Map 中获取到对应的 Bean 对象，这样也就省去了 `if···else` 大量的判断操作。 + +### 2. 空注入判断 + +```java +public class NullAwardService implements IAwardService { + + @Override + public void doDistributeAward(String userId) { + + } + +} + +@Autowired(required = false) +private NullAwardService nullAwardService; +``` + +- **场景**：NullAwardService 没有配置 @Service 注册，或者在程序中手动实例化的这个 Bean 对象，根据不同诉求，在没有创建的时候。可以使用 `@Autowired(required = false)` 进行注入。这样就不会报错 nullAwardService 空指针异常。 +- **用途**：当我们在使用支付、openai外部接口对接测试阶段，可能有些时候是需要关闭服务的，也就是不实例化对象。那么这个时候就配置 `@Autowired(required = false)` 避免注入空指针 + +### 3. 优先实例化 + +```java +@Slf4j +@Service("openai_model") +// Primary 首选 Bean 对象标记 +@Primary +@Order(1) +public class OpenAIModelAwardService implements IAwardService { + + @Override + public void doDistributeAward(String userId) { + log.info("发奖服务，OpenAI 模型奖励 {}", userId);

+``` + +- **场景**：是一个案例中使用到了 `@ConditionalOnProperty` 注解，我们也可以自定义一个 Conditional 的实现类，之后把这个实现类配置到需要实例化的对象上面，通过 matches 匹配条件方法的实现，决定是否实例化。 +- **用途**：这个场景的用途和 `@ConditionalOnProperty` 是一样的，只不过我们可以更好的自定义控制。 + +### 7. 根据环境配置实例化对象 + +```java +@Slf4j +@Service +// 用于根据配置环境实例化 Bean 对象 +@Profile({"prod", "test"}) +@Lazy +public class AliPayAwardService implements IAwardService { + + public AliPayAwardService() { + log.info("如一些支付场景，必须指定上线后才能实例化");

+} +``` + +- **场景**：`@Scope("prototype")` 可以设定对象类型为原型对象，每次获得的对象都是一个新的实例化对象。 +- **用途**：对于动态，不同责任链创建，可以使用这个配置，确保每个对象都是自己的。 + +### 10. 其他注解 + +- `@EnableScheduling`：允许启动任务的注解，放到 Application 上，确保任务启动执行。 +- `@DependsOn({"openai_model", "openai_use_count", "user_credit_random"})` Bean 对象实例化中，依赖于哪些对象。 +- `@Autowired private Environment env;` 环境配置注入，可以获取到 application.yml 中的配置数据 `env.getProperty("app.name"), env.getProperty("app.version")` +- `@Async` 异步方法注解，可以用于调用某个方法后，让下面的具体逻辑方法为异步执行，主方法直接返回结果。可以用于一些申请导出数据到文件的场景。 + +## 三、源码分析 + +这里的 Map 注入比较有特点，小傅哥把它的流程和核心代码给大家描述下，方便感兴趣源码的伙伴，可以去看下源码调试跟进。 + +
+ +
+ +在 Spring 框架中，依赖注入（DI）是通过一系列的步骤和组件来实现的。对于构造函数注入，特别是注入 `Map` 类型的依赖，Spring 需要处理以下几个关键步骤： + +1. **Bean Definition 解析**：Spring 解析配置文件或注解，生成 BeanDefinition 对象。 +2. **Bean 实例化**：Spring 根据 BeanDefinition 创建 Bean 实例。 +3. **依赖注入**：Spring 将所需的依赖注入到 Bean 中。 + +### 1. 核心源码 + +具体到构造函数注入 `Map` 类型的依赖，Spring 主要通过以下源码来处理： + +#### 1.1 `AutowiredAnnotationBeanPostProcessor` + +```java +public class AutowiredAnnotationBeanPostProcessor implements BeanPostProcessor { + // 省略其他代码 + + @Override + public PropertyValues postProcessProperties(PropertyValues pvs, Object bean, String beanName) { + InjectionMetadata metadata = findAutowiringMetadata(beanName, bean.getClass(), pvs); + try { + metadata.inject(bean, beanName, pvs); + } catch (Throwable ex) { + throw new BeanCreationException(beanName, "Injection of autowired dependencies failed", ex); + } + return pvs; + } +} +``` + +`AutowiredAnnotationBeanPostProcessor` 是处理依赖注入的核心类之一。它会扫描 Bean 的构造函数、字段和方法上的 `@Autowired` 注解，并进行相应的依赖注入。 + +#### 1.2 `ConstructorResolver` + +```java +public class ConstructorResolver { + // 省略其他代码 + + public BeanWrapper autowireConstructor( + final String beanName, final RootBeanDefinition mbd, Constructor[] chosenCtors, final Object[] explicitArgs) { + + // 省略其他代码 + + Constructor constructorToUse = null; + ArgumentsHolder argsHolderToUse = null; + Object[] argsToUse = null; + + // 省略其他代码 + + for (Constructor candidate : candidates) { + Class[] paramTypes = candidate.getParameterTypes(); + if (argsToUse == null) { + // 省略其他代码 + argsHolder = createArgumentArray( + beanName, mbd, resolvedValues, bw, paramTypes, paramNames, getUserDeclaredConstructor(candidate), autowiring); + } + // 省略其他代码 + } + + // 省略其他代码 + + BeanWrapperImpl bw = new BeanWrapperImpl(beanInstance); + initBeanWrapper(bw); + + return bw; + } +} +``` + +`ConstructorResolver` 是负责解析和调用构造函数的类。它会根据 BeanDefinition 和构造函数的参数类型，选择合适的构造函数并进行实例化。 + +#### 1.3 `DefaultListableBeanFactory` + +```java +public class DefaultListableBeanFactory extends AbstractAutowireCapableBeanFactory + implements ConfigurableListableBeanFactory, BeanDefinitionRegistry { + + // 省略其他代码 + + @Override + protected Map findAutowireCandidates(String beanName, Class requiredType, DependencyDescriptor descriptor) { + String[] candidateNames = BeanFactoryUtils.beanNamesForTypeIncludingAncestors(this, requiredType); + Map result = new LinkedHashMap<>(candidateNames.length); + for (String candidate : candidateNames) { + if (!isSelfReference(beanName, candidate) && isAutowireCandidate(candidate, descriptor)) { + result.put(candidate, getBean(candidate)); + } + } + if (result.isEmpty() && !indicatesMultipleBeans(requiredType)) { + DependencyDescriptor fallbackDescriptor = descriptor.forFallbackMatch(); + for (String candidate : candidateNames) { + if (!isSelfReference(beanName, candidate) && isAutowireCandidate(candidate, fallbackDescriptor)) { + result.put(candidate, getBean(candidate)); + } + } + } + return result; + } +} +``` + +`DefaultListableBeanFactory` 是 Spring 中最常用的 BeanFactory 实现类。它负责管理 Bean 的定义和生命周期，并提供依赖查找和注入的功能。 + +### 2. 具体流程 + +1. **解析 BeanDefinition**： + Spring 解析配置文件或注解，生成 `AwardController` 的 `BeanDefinition` 对象。 +2. **选择构造函数**： + `AutowiredAnnotationBeanPostProcessor` 会扫描 `AwardController` 的构造函数，发现它有一个 `Map` 类型的参数。 +3. **查找依赖**： + `ConstructorResolver` 会根据构造函数参数的类型，查找 Spring 容器中所有 `IAwardService` 类型的 Bean，并将它们放入一个 `Map` 中。这个 `Map` 的键是 Bean 的名称，值是对应的 `IAwardService` 实例。 +4. **实例化 Bean**： + `ConstructorResolver` 使用找到的依赖，调用 `AwardController` 的构造函数，创建 `AwardController` 实例。 +5. **注入依赖**： + `DefaultListableBeanFactory` 将创建好的 `Map` 注入到 `AwardController` 的构造函数中。 diff --git a/docs/md/road-map/spring-oauth2-sso-01.md b/docs/md/road-map/spring-oauth2-sso-01.md new file mode 100644 index 000000000..9e029ad50 --- /dev/null +++ b/docs/md/road-map/spring-oauth2-sso-01.md @@ -0,0 +1,502 @@ +--- +title: OAuth2 SSO +lock: need +--- + +# OAuth2 SSO - 前后端分离，单点登录案例 + +作者：小傅哥 +

+ +
+ +其实在公司里是一套统一的授权服务和组件的，并且维护用户的ID、用户的关联绑定也都是这套系统来处理的。之后这套系统会和 API 网关进行对接，等网关下发到你的后端服务系统时，在内部微服间流转就是真实的用户ID啦。 + +那么为了让伙伴们更好的理解关于 OAuth2 SSO 统一单点登录的前后端分离服务，小傅哥这里做了一个结合 Spring Security OAuth2很容易理解案例工程。学习后就可以扩展使用 SSO 到你自己的系统了，比如可以做一个统一的用户鉴权中心。 + +## 一、单点登录 + +单点登录（Single Sign-On，SSO）是一种认证技术，用户只需进行一次身份验证，就可以访问多个相互信任的应用系统，而无需再次输入凭证。SSO的主要目的是简化用户的登录过程，提高用户体验和安全性，同时减少管理多个用户名和密码的复杂性。 + +
+ +
+ +SSO的工作原理通常涉及以下几个步骤： + +1. **身份验证**：用户在第一次访问SSO系统时输入用户名和密码等凭据进行验证。 +2. **创建会话**：成功验证后，系统创建一个会话，可以是令牌、票证或其他凭据，以证明用户的身份。 +3. **访问授权**：当用户访问不同的应用时，SSO系统将会话信息传递给这些应用，以确认用户的身份并授予访问权限。 +4. **信任机制**：应用之间需要建立信任关系，通常通过共享密钥或使用公钥基础设施（PKI）来实现验证和授权。 + +SSO的优点包括： + +- **提高用户体验**：用户只需记住一个用户名和密码，减少了填写登录信息的次数。 +- **增强安全性**：集中管理用户身份，方便监控和保护密码策略。 +- **降低管理成本**：减少IT部门处理密码重置等事务的工作量。 + +## 二、案例工程 + +### 1. 编程环境 + +- JDK 1.8 + +- SpringBoot 2.6.2 + +- Maven 3.8.1 + +- Docker - 负责安装 Nginx，如果没有 Docker 就本地直接安装 Nginx + +- SwitchHosts - 切换host，映射自定义域名地址，可以避免跨域问题。如果没有就直接修改本地的 host 文件。你可以配置自己的。 + +```java +192.168.1.107 sso.xfg.com +192.168.1.107 client1.xfg.com +192.168.1.107 client2.xfg.com +``` + +- 工程：[https://github.com/fuzhengwei/xfg-dev-tech-oauth2-sso](https://github.com/fuzhengwei/xfg-dev-tech-oauth2-sso) + +### 2. 工程结构 + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +你知道互联网大厂最怕的是什么吗？但凡有点这样的风吹草动，我们就要花费大量的时间进行修复和上线。一点都不敢耽误，对于紧急类型的，基本当天发现，当天就要升级上线。那是什么问题呢？🤔 + +
+ +
+ +**其实最怕的就是各类组件漏洞！** + +有这么一个东西，[13scan - 安全漏洞扫描](https://bugstack.cn/md/road-map/13scan-jdumpspider.html) 它可以扫描出系统组件的各项存在的漏洞，给出整改建议。因为这些漏洞的存在，就可能让不法用户通过接口调用到系统数据。比如，随意输入个订单号，就知道是谁，什么时间、购买的什么、地址在哪。这是非常可怕的。 + +所以，在互联网大厂中，会有统一的安全授权认证服务 OAuth2。这样即使有外部对接的系统确实需要授权获得用户的数据，也可以在可靠的范围内进行授权和使用。 + +那么，OAuth2 是个啥呢？🤔 本节我们来分享下并做个代码案例运行验证。 + +## 一、OAuth2 是啥？ + +**OAuth 2.0 的标准 RFC 6749，解释了 OAuth 是什么。** + +
+ +
+ +**官网**：[https://datatracker.ietf.org/doc/html/rfc6749](https://datatracker.ietf.org/doc/html/rfc6749) + +OAuth 2.0 本身是一种开放标准，不是一个具体的服务类组件，而是一种标准。旨在为用户提供授权，允许第三方应用程序访问用户在某个服务提供者（如社交网络或云服务）上的信息，而无需将用户的凭证（如用户名和密码）透露给这些应用程序。OAuth 2.0 主要用于授权，而不是身份验证。 + +而 Spring 中 OAuth2 就是对这套标准的具体实现，但这不是唯一实现，你甚至可以通过这套标准做一套自己的 OAuth2 授权框架。 + +## 二、举个例子 + +大家在日常的生活中使用互联网类的产品，包括；购物、视频、出行等，都可能收到活动类的短信，问你是否要参与一个这样的活动，如果参与则需要点击授权允许。那么这个过程就有 OAuth2 的授权使用。如图； + +
+ +
+ +- 这是一套用户参与小傅哥分享的星球用户活动页面。用户点击参与后，会引导进入授权验证。显示进入微信登录，之后跳转到用户数据授权使用页。 +- 用户允许授权后，小傅哥的这套活动页就可以拿到用户个人的数据，通过个人的数据为唯一标识，允许用户参与本次活动。这些活动可以是一些抽奖、礼包领取、代码仓库授权等。这些场景的使用，就是 OAuth2 的授权框架作用。 + +## 三、授权方式 + +在看 OAuth2 之前，可以代入的思考下，如果是你做一个认证授权框架，你会怎么做。其实你在最开始学习编程使用账号密码在数据库里匹配验证，完成后生成一个 Token 让前端保存到 Cookie 里，之后每次请求后端都携带上这个 Cookie 进行校验。 + +其实这个模型就是认证授权框架。认证；使用账密证明你是你，授权，则通过账密分配一个Token，让使用放通过 Token 进行数据访问。 + +那么，OAuth2 作为认证授权框架，提供了四种授权访问，包括； +- 授权模型（authorization-code） +- 隐藏模式（简单授权）（implicit） +- 密码模式（password） +- 客户端凭证模式（client credentials） + +这四种授权方式，逐渐减弱。不过，无论那种授权方式，在第三方应用申请可调用数据的令牌前，都需要先完成系统备案，验明自身身份。包括客户端 ID、客户端秘钥 Client Secret。 + +### 1. 授权模型 + +授权模式：指第三方应用先申请一个授权码，之后再使用该码获得令牌。授权码模式通常用于具有浏览器界面的应用程序，尤其是在需要用户交互的场景下，例如传统的Web应用。由于使用了重定向和授权码，维护了更高的安全性。 + +
+ +
+ +**工作流程：** + +1. 用户在客户端（第三方应用）上点击登录。 +2. 客户端将用户重定向到授权服务器，携带其注册的客户端ID、重定向URI和请求的权限范围。 +3. 用户在授权服务器上验证身份，并同意授权后，授权服务器将用户重定向回客户端，附带一个授权码。 +4. 客户端使用该授权码向授权服务器请求访问令牌，同时发送客户端ID、客户端密钥和重定向URI。 +5. 授权服务器验证请求，并返回访问令牌（和可选的刷新令牌）。 +6. 客户端使用访问令牌访问受保护的资源。 + +### 2. 隐藏模式 + +隐式模式主要适用于在Web浏览器中运行的单页应用（SPA）等不安全的客户端环境，因为不需要后台服务器交换授权码，简化了流程。然而，隐式模式由于直接暴露令牌，安全性较低，不建议用于敏感操作。 + +
+ +
+ +**工作流程：** + +1. 用户在客户端上点击登录。 +2. 客户端将用户重定向到授权服务器，携带客户端ID、重定向URI及请求的权限范围。 +3. 用户在授权服务器进行身份验证，并同意授权后，授权服务器立即将访问令牌作为URI片段重定向回客户端。 +4. 客户端在接收到重定向后，解析URI以获取访问令牌，随后可直接使用该令牌访问受保护的资源。 + +### 3. 密码模式 + +密码模式适用于用户信任客户端的情况，如用户通过原生应用（移动应用）访问服务。在此情况下，客户端直接处理用户的凭据，使用时要确保应用的安全性。 + +
+ +
+ +**工作流程：** + +1. 用户在客户端直接输入其用户名和密码。 +2. 客户端将用户的凭据（用户名和密码）发送到授权服务器，请求访问令牌。 +3. 授权服务器验证凭据并返回访问令牌（和可选的刷新令牌）。 +4. 客户端使用访问令牌访问受保护的资源。 + +### 4. 客户端凭证模式 + +客户端凭证模式主要用于服务器与服务器之间的通信，如后台服务相互访问API，或者服务自身需要访问其资源。适用于没有用户上下文的场景，更多用于机器对机器（M2M）通信。 + +
+ +

博客：[https://bugstack.cn](https://bugstack.cn) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +大家好，我是技术UP主小傅哥。 + +在互联网大厂这些年做研发这么多年，有一个非常指导性的开发原则就是；你做的这个东西是否能让整个大组内的其他系统使用。所以，从15年入职开始，我有的各种创新的想法都落地实现了，一直被使用到现在。`那些组件也都成了一个个技术专利 👍🏻` + +
+ +
+ +但其实这样对通用逻辑的共性凝练，开发成统一的组件，在 Spring 框架中是有非常多的，这些东西也都在我们日常使用 Spring 时有所涉猎。包括我们本节要讲解的 Spring Security 组件。 + +当你想让系统实现登录校验的服务，那么你不可能在每个系统里都写认证和授权服务，那么这个时候就要做一套统一的认证框架。这里 Spring Security 就是专注于为 Java 应用程序提供身份验证和授权的框架。提供；验证、授权、防止会话固定、点击劫持、跨域请求等。 + +## 一、为啥需要安全框架 + +举个例子；SpringBoot 有一个 actuator 框架，可以配合普罗米修斯做系统监控。包括采集系统的接口运行数据、JVM 信息、负载等各项指标。 + +```java +# 监控 +management: + endpoints: + web: + exposure: + include: "*" + endpoint: + health: + show-details: always + metrics: + export: + prometheus: + enabled: true + prometheus: + enabled: true +``` + +虽然很好用，但如果你一点安全都不加就直接在工程中配置，那么在网安人员的手里，基本就是一台肉鸡。一套 w13scan 正向代理，就能把你的工程底裤拔掉，拿出你的数据库账号密码。 + +操作教程：[https://bugstack.cn/md/road-map/13scan-jdumpspider.html](https://bugstack.cn/md/road-map/13scan-jdumpspider.html) + +```java +/bin/zsh /xiaofuge/develop/github/xfg-dev-tech-w13scan-jdumpspider/docs/jdumpspider.sh +(base) xiaofuge@ZBMac-GV47H1GXD docs % /bin/zsh /Users/xiaofuge/Documents/develop/github/xfg-dev-tech-w13scan-jdumpspider/docs/jdumpspider.sh +=========================================== +SpringDataSourceProperties +------------- +password = 123456 +driverClassName = com.mysql.cj.jdbc.Driver +url = jdbc:mysql://127.0.0.1:13306/road_map?useUnicode=true&characterEncoding=utf8&autoReconnect=true&zeroDateTimeBehavior=convertToNull&serverTimezone=UTC&useSSL=true +username = root +``` + +所以，任何你暴漏出去对外使用的服务，都要做安全框架的认证和授权。 + +## 二、认证和授权的原理 + +有不少伙伴在初次使用 Spring Security 框架的时候，会觉得复杂度有些高。其实在之前没有 SpringBoot 之前，Security 这个框架使用是更复杂的。这也主要是因为 Security 支持的灵活性更高，所以抽象的也更复杂。但其实能做一个完整的小案例，也就不会觉得有多复杂了。 + +
+ +
+ +- 其实 Spring Security 要做也就2件事，认证（Authentication）你是谁，授权（Authorization）你干啥。其实就算你不使用 Spring Security 你自己做一个登录的功能，以及允许登录的用户可以操作的流程，也要做这样的事情。 +- Spring Security 在内部维护一个过滤器链，其中每个过滤器都有特定的职责，并且根据所需的服务在配置中添加或删除过滤器。过滤器的顺序很重要，因为它们之间存在依赖关系。 +- 文档：[https://docs.spring.io/spring-security/site/docs/3.0.x/reference/security-filter-chain.html](https://docs.spring.io/spring-security/site/docs/3.0.x/reference/security-filter-chain.html) - Web 应用程序安全过滤链 + +## 三、一个简单的小案例 + +Spring Security 提供了最简单的登录访问校验配置，如果你只是想给一些页面添加一个登录页面。那么只需要配置下 pom 和 yml 中提供的用户账密就可以登录校验了。 + +源码：[https://github.com/fuzhengwei/xfg-dev-tech-spring-security-demo](https://github.com/fuzhengwei/xfg-dev-tech-spring-security-demo) + +### 1. 引入 pom + +```java + + org.springframework.boot + spring-boot-starter-security + +``` + +### 2. 配置yml + +```java +server: + port: 8099 + +spring: + security: + user: + name: xiaofuge + password: 123456 +``` + +- security 的账号密码，就是你访问一个链接需要登录的账密。 +- 如果不配置账号，它会有一个固定的 user 加上在启动程序时控制台会随机生成密码。 + +### 3. 测试接口 + +```java +@RestController +@RequestMapping("/api/auth/") +public class TestController { + + @GetMapping("hi") + public String hi(){ + return "hi security"; + } +} +``` + +### 4. 访问验证 + +地址：[http://localhost:8099/api/test/hi](http://localhost:8099/api/test/hi) + +
+ +
+ +- 首次访问地址后，会自动跳转到一个登录页面。属于我们配置的账密进行登录。登录完成后，这里会写入一个 cookie，之后就可以访问我们的接口信息了。 + +## 四、正式工程案例对接 + +### 1. 工程结构 + +
+ +
+ +- 地址：[https://github.com/fuzhengwei/xfg-dev-tech-spring-security](https://github.com/fuzhengwei/xfg-dev-tech-spring-security) +- 这是一套在 DDD 六边形分层结构中添加的 Spring Security 认证框架。如图，介绍了分层模块的使用。 +- 接下来我们注册讲解这些代码块的用途。 + +### 2. GuavaConfig - 本地缓存模拟用户 + +```java +@Slf4j +@Configuration +public class GuavaConfig { + + @Bean(name = "userCache") + public Cache userCache(PasswordEncoder passwordEncoder) { + Cache cache = CacheBuilder.newBuilder() + .expireAfterWrite(365, TimeUnit.DAYS) + .build(); + + UserEntity userEntity01 = UserEntity.builder() + .userName("xiaofuge") + .password(passwordEncoder.encode("123456")) + .roles(Arrays.asList(RoleTypeEnum.ADMIN)) + .build(); + + UserEntity userEntity02 = UserEntity.builder() + .userName("liergou") + .password(passwordEncoder.encode("123456")) + .roles(Arrays.asList(RoleTypeEnum.USER)) + .build(); + + log.info("测试账密01 xiaofuge/123456 权限；admin"); + log.info("测试账密02 liergou/123456 权限；user"); + + cache.put(userEntity01.getUserName(), userEntity01); + cache.put(userEntity02.getUserName(), userEntity02); + return cache; + } + +} +``` + +- 程序启动后，模拟注册完成的用户用户测试验证。用户也可以在测试中自己在注册用户。 + +### 3. UserDetails 用户身份信息 + +#### 3.1 身份实现 + +```java +public class UserDetailAuthSecurity implements UserDetails { + + @Serial + private static final long serialVersionUID = 931859819772024712L; + + private final UserEntity userEntity; + + public UserDetailAuthSecurity(UserEntity userEntity) { + this.userEntity = userEntity; + } + + @Override + public Collection getAuthorities() { + return userEntity.getRoles() + .stream() + .map(role -> new SimpleGrantedAuthority("ROLE_" + role.getCode())) + .collect(Collectors.toList()); + } + + @Override + public String getPassword() { + return userEntity.getPassword(); + } + + @Override + public String getUsername() { + return userEntity.getUserName(); + } + + // ... + +} +``` + +- 做授权校验是基于用户的 UserDetails 详细身份进行的。这东西就是一个依赖倒置，Spring 定义好接口标准，之后由使用方实现。 + +#### 3.2 身份获取 + +```java +@Service +public class UserDetailsServiceImpl implements UserDetailsService { + + @Resource + private Cache userCache; + + @Override + public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { + UserEntity userEntity = userCache.getIfPresent(username); + if (null == userEntity) return null; + return new UserDetailAuthSecurity(userEntity); + } + +} +``` + +- 这里还需要对 UserDetails 包装一层提供一个 UserDetailsService 接口的实现类。 + +### 4. 授权&校验处理 + +#### 4.1 JwtAuthenticationProvider - 验证账密 + +```java +public class JwtAuthenticationProvider implements AuthenticationProvider { + + private final PasswordEncoder passwordEncoder; + private final UserDetailsService userDetailsService; + + public JwtAuthenticationProvider(PasswordEncoder passwordEncoder, UserDetailsService userDetailsService) { + this.passwordEncoder = passwordEncoder; + this.userDetailsService = userDetailsService; + } + + @Override + public Authentication authenticate(Authentication authentication) throws AuthenticationException { + String username = String.valueOf(authentication.getPrincipal()); + String password = String.valueOf(authentication.getCredentials()); + + UserDetails userDetails = userDetailsService.loadUserByUsername(username); + if (passwordEncoder.matches(password, userDetails.getPassword())) { + return new UsernamePasswordAuthenticationToken(username, password, userDetails.getAuthorities()); + } + + throw new BadCredentialsException("Auth Error!"); + } + + @Override + public boolean supports(Class authentication) { + return UsernamePasswordAuthenticationToken.class.equals(authentication); + } + +} +``` + +- 这一部分是获取用户名和密码，通过 userDetailsService 获取信息进行密码比对。这个就和我们自己要做一个登录校验的方式是一样的。 + +#### 4.2 JwtAuthenticationTokenFilter - 校验登录 + +```java +@Slf4j +public class JwtAuthenticationTokenFilter extends OncePerRequestFilter { + + private final static String AUTH_HEADER = "Authorization"; + private final static String AUTH_HEADER_TYPE = "Bearer"; + + private final UserDetailsService userDetailsService; + + public JwtAuthenticationTokenFilter(UserDetailsService userDetailsService) { + this.userDetailsService = userDetailsService; + } + + @Override + protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException { + String authHeader = request.getHeader(AUTH_HEADER); + if (Objects.isNull(authHeader) || !authHeader.startsWith(AUTH_HEADER_TYPE)){ + filterChain.doFilter(request,response); + return; + } + + String authToken = authHeader.split(" ")[1]; + log.info("authToken:{}" , authToken); + + if (!JWTUtil.verify(authToken, "key".getBytes(StandardCharsets.UTF_8))) { + filterChain.doFilter(request,response); + return; + } + + final String userName = (String) JWTUtil.parseToken(authToken).getPayload("username"); + UserDetails userDetails = userDetailsService.loadUserByUsername(userName); + + UsernamePasswordAuthenticationToken authentication = + new UsernamePasswordAuthenticationToken(userDetails.getUsername(), userDetails.getPassword(), userDetails.getAuthorities()); + authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request)); + + SecurityContextHolder.getContext().setAuthentication(authentication); + + filterChain.doFilter(request, response); + } + +} +``` + +```java +fetch(url, { + method: 'POST', + headers: { + 'Content-Type': 'application/json', + 'Authorization': `Bearer ${token}` // Include the token in the request headers + } +}) +``` + +- 这一部分是对 http 请求信息中的 Authorization Bearer 后面带有的 token 信息进行解析校验。如代码中提供了一部分前端请求代码，就是这里的 Token + +### 5. 认证&授权配置 + +```java +@Configuration +@EnableWebSecurity +@EnableMethodSecurity(prePostEnabled = true) +public class SpringSecurityConfig { + + // 不拦截的 URL + private final String[] requestMatchers = {"/api/auth/login", "/api/auth/register", "/api/auth/query_user_name", "/test/**"};

+ } + + @Bean + public JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter(UserDetailsService userDetailsService) { + return new JwtAuthenticationTokenFilter(userDetailsService); + } + + @Bean + public JwtAuthenticationProvider jwtAuthenticationProvider(PasswordEncoder passwordEncoder, UserDetailsService userDetailsService) { + return new JwtAuthenticationProvider(passwordEncoder, userDetailsService); + } + + @Bean + public SecurityFilterChain filterChain(HttpSecurity httpSecurity, + JwtAuthenticationProvider jwtAuthenticationProvider, + JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter, + AppUnauthorizedHandler appUnauthorizedHandler, + AppAccessDeniedHandler appAccessDeniedHandler + ) throws Exception { + // 使用JWT，可屏蔽csrf防护 + httpSecurity.csrf(CsrfConfigurer::disable) + // 基于token存储到浏览器，不需要session + .sessionManagement(sessionManagementConfigurer -> sessionManagementConfigurer.sessionCreationPolicy(SessionCreationPolicy.STATELESS)) + .authorizeHttpRequests(authorizationRegistry -> authorizationRegistry + // 允许对于网站静态资源的无授权访问 + .requestMatchers(HttpMethod.GET, "/", "/*.html").permitAll() + // 对登录注册允许匿名访问 + .requestMatchers(requestMatchers).permitAll() + // 访问授权，所有 /user/** 路径下的请求需要 ADMIN 角色。注意；Spring Security在处理角色时，会自动为角色名添加"ROLE_"前缀。因此，"ADMIN"角色实际上对应权限"ROLE_ADMIN"。 + .requestMatchers("/api/mall/**").permitAll() + // 跨域请求会先进行一次options请求 + .requestMatchers(HttpMethod.OPTIONS).permitAll() + // 对所有请求开启授权保护 + .anyRequest() + // 已认证的请求自动被授权 + .authenticated() + ) + // 禁用缓存 + .headers(headersConfigurer -> headersConfigurer + .cacheControl(HeadersConfigurer.CacheControlConfig::disable) + ) + // 使用自定义 provider + .authenticationProvider(jwtAuthenticationProvider) + // 添加 JWT filter + .addFilterBefore(jwtAuthenticationTokenFilter, UsernamePasswordAuthenticationFilter.class) + // 添加自定义未授权和未登录结果返回 + .exceptionHandling(exceptionConfigure -> exceptionConfigure + .accessDeniedHandler(appAccessDeniedHandler) + .authenticationEntryPoint(appUnauthorizedHandler)); + + return httpSecurity.build(); + } + +} +``` + +- 那么这里所做的就是认证授权的配置，对哪些URL进行放行，哪些是要做拦截。 +- appAccessDeniedHandler、appUnauthorizedHandler，是自定义的鉴权拦截，如果登录不通过，可以统一返回给前端一个固定的错误码，便于跳转登录。 + +### 6. 注册登录 + +```java +@Service +public class AuthService implements IAuthService { + + @Autowired + private PasswordEncoder passwordEncoder; + + @Resource + private Cache userCache; + + @Autowired + private AuthenticationManager authenticationManager; + + @Override + public void register(String userName, String password) { + + UserEntity userEntity = UserEntity.builder() + .userName(userName) + .password(passwordEncoder.encode(password)) + .roles(Arrays.asList(RoleTypeEnum.USER, RoleTypeEnum.ADMIN)) + .build(); + + userCache.put(userName, userEntity); + } + + @Override + public String login(String userName, String password) { + // 登录验证 + authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(userName, password)); + // 验证通过，获取 token + String token = JWT.create() + .setExpiresAt(new Date(System.currentTimeMillis() + (1000 * 30))) + .setPayload("username", userName) + .setKey("key".getBytes(StandardCharsets.UTF_8)) + .sign(); + + return token; + } + +} +``` + +- 在 domain 模块中提供了一个简单的注册&登录服务。注册就是简单的像本地缓存 Guava 写入数据。登录校验会调用登录密码校验处理。在登录成功后返回 JWT 生成的 token 信息。 + +### 7. 访问拦截 + +#### 1. 认证授权 + +```java +@Slf4j +@CrossOrigin("*") +@RestController +@RequestMapping("/api/auth/") +public class AuthController { + + @Resource + private IAuthService authService;

+ } + } + +} +``` + +- 提供注册、登录和查询用户信息接口。 +- 查询用户有些场景是会通过路径地址获取用户id，再根据用户id查询。但一些安全级别较高的，甚至不会透彻用户id，而是校验登录token，之后缓存用户id在使用。 + +#### 2. 角色权限 + +```java +@Slf4j +@CrossOrigin("*") +@RestController +@RequestMapping("/api/mall/") +public class MallController { + + @PreAuthorize("hasRole('ADMIN')") +// @PreAuthorize("hasRole('USER')") + @RequestMapping(value = "create_pay_order", method = RequestMethod.POST) + public Response createPayOrder(@RequestBody CreatePayRequestDTO createPayRequestDTO) { + try { + // 获取当前认证的用户信息 + Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

+ +
+ +**在大厂这个组件叫什么？** + +这个东西它不同于 Redis，而是把配置写到本地类对应的属性上。而不是像 Redis 那样从一个统一的地方每次去取使用。在大厂中我们管这个组件叫统一配置中，专门应对分布式工程中类对应属性的值的控制。 + +在小傅哥的大营销项目中，也带着大家实现过这样一款组件，叫[DCC](https://bugstack.cn/md/project/big-market/api/%E7%AC%AC29%E8%8A%82%EF%BC%9A%E5%88%86%E5%B8%83%E5%BC%8F%E5%8A%A8%E6%80%81%E9%85%8D%E7%BD%AE%E6%B4%BB%E5%8A%A8%E9%99%8D%E7%BA%A7.html)，基于 Zookeeper + AOP 切面实现。 + +那么我们本节来看看 SpringCloud 是如何来处理这样一个场景的。 + +## 一、组件介绍 + +Spring Cloud Bus 将分布式系统的节点与轻量级消息代理相链接。然后可以使用它来广播状态更改（例如配置更改）或其他管理指令。该项目包含 AMQP 和 Kafka 代理实现。 + +

+ +
+ +1. **基于异步非阻塞模型**：Spring Cloud Gateway 基于 Project Reactor 和 WebFlux，采用了异步非阻塞的 API，可以提供更高的吞吐量和更低的延迟。 +2. **动态路由**：可以通过配置文件或者 API 动态地添加、修改或删除路由规则，不需要重启服务。 +3. **路由断言**：可以根据 HTTP 请求的各种参数（如路径、头部、请求参数等）来匹配路由。 +4. **过滤器**：提供了一系列内置的 GatewayFilter 工厂，可以在请求被路由前或后执行各种操作，如修改请求头、增加参数、限流等。同时也支持自定义过滤器。 +5. **集成与安全**：可以与 Spring Cloud 的服务发现和断路器等组件无缝集成，同时也可以集成 Spring Security 实现安全控制。 +6. **限流与熔断**：可以集成如 Resilience4J 等库来实现限流和熔断功能，保护后端服务不被过多的请求压垮。 +7. **监控与跟踪**：可以与 Spring Cloud Sleuth 和 Zipkin 等组件集成，实现请求的跟踪和监控。 + +Spring Cloud Gateway 的工作原理是将进入的 HTTP 请求根据配置的路由规则转发到对应的后端服务。它在转发请求的过程中可以执行一系列的过滤器链，这些过滤器可以修改请求和响应，或者根据特定的逻辑决定是否继续处理请求。 + +## 二、环境部署 + +### 1. 测试工程 + +
+ +
+ +- 注意；本机安装了 docker 或者云服务器安装了 docker + compose。在小傅哥的 [bugstack.cn](https://bugstack.cn/md/road-map/docker.html) 路书系列教程中，有云服务器操作。 +- 在小傅哥提供的案例工程中，包括；环境配置（nacos - 注册中心、redis - 限流使用）、curl 测试访问网关地址、app 是网关配置、provider-01\02 是2个测试工程，提供了2个接口，方便验转发。 +- 最后的 webflux 是使用这项技术来模拟开发网关，让大家了解到 SpringCloud Gateway 简单运行机制。 + +### 2. 基础环境 + +- 开发环境：JDK 17 +- 云服务器：2c4g 最低，我是用的 2c8g 体验的。[https://yun.xfg.plus](https://yun.xfg.plus/)- 价格实惠。 +- 基础环境：Docker、Portainer、Git 【在小傅哥的 bugstack.cn 路书中都有讲解安装和使用】 + +

+ +
+ +- 通过 routerFunction 对不同的请求地址进行转发操作。 +- 如图 `curl http://localhost:9091/wg/service1/8091`、`curl http://localhost:9091/wg/service2/8092` 可以得到不同的响应结果。 + +## 四、网关测试 - SpringCloud Gateway + +
+ +
+ +- 文档：[https://docs.spring.io/spring-cloud-gateway/docs/current/reference/html](https://docs.spring.io/spring-cloud-gateway/docs/current/reference/html) +- 使用：你可以右键翻译文档，根据文档的说明来配置各个场景验证网关使用。 + +### 1. yml配置 + +```java +spring: + redis: + host: 127.0.0.1 + port: 16379 + database: 0 + lettuce: + pool: + max-active: 10 + max-wait: 1000 + max-idle: 5 + min-idle: 3 + application: + name: xfg-dev-tech-springcloud-gateway + cloud: + nacos: + discovery: + server-addr: 127.0.0.1:8848 + username: nacos + password: nacos + locator: + enabled: true + gateway: + discovery: + locator: + enabled: true + globalcors: + cors-configurations: + '[/**]': + allowedOrigins: "*" + allowedMethods: "*" + alloedHeaders: "*" + routes: + - id: route_01 + uri: lb://provider-01 + order: 1 + predicates: + - Path=/gw/** + - Weight=group1, 1 + filters: + - StripPrefix=1 + - id: route_02 + uri: lb://provider-02 + order: 1 + predicates: + - Path=/gw/** + - Weight=group1, 9 + filters: + - StripPrefix=1 + - name: RequestRateLimiter + args: + key-resolver: "#{@ipKeyResolver}" # 限流方式：Bean名称 + redis-rate-limiter.replenishRate: 1 # 生成令牌速率：个/秒 + redis-rate-limiter.burstCapacity: 3 # 令牌桶容量 + redis-rate-limiter.requestedTokens: 1 # 每次消费的Token数量 +``` + +- 配置 Redis 是为了使用限流组件，同时要配置 RequestRateLimiter 类，配置对应的限流 bean 名称。 +- nacos 是注册中心，网关走的是 nacos 注册中心里的服务。这些服务是生产者接口配置了 nacos 注册到注册中心了。这样就可以通过 lb://provider-02 进行访问。lb = nacos，provider-02 是生产者配置的服务名称。 +- 在 yml 配置中，一组 id: route_01 下面是对应的网关配置，以这个距离，访问 `Path=/gw/**` 路径，filters 过滤掉 `StripPrefix=1` 1个路径 gw 其余的打到 provider-01 服务上，也就是可以访问具体的服务了。另外 `Weight=group1, 1` 是权重配置，group1 代表这一组的，1 表示权重比。*如果你不用 nacos，uri 也可以配置一个具体的 http 地址测试* +- 这些内容在 SpringCloud Gateway 官网有对应的介绍，直接按照文档配置使用即可。 + +### 2. 代码配置 + +**源码**：`cn.bugstack.xfg.dev.tech.config.RouteConfiguration` + +```java +@Bean +public RouteLocator route(RouteLocatorBuilder builder, UriConfiguration uriConfiguration) { + String httpUri = uriConfiguration.getHttp(); + return builder.routes() + .route(p -> p.path("/baidu").uri("https://www.baidu.com/")) + .route(p -> p.path("/bugstack").uri("https://bugstack.cn/md/road-map/road-map.html")) + .route(p -> p.path("/error").uri("forward:/fallback")) + .route(p -> p.path("/get").filters(f -> f.addRequestHeader("Hello", "World")).uri(httpUri)) + .build(); +} +``` + +- 除了 yml 中的配置，还可以使用代码配置。有代码配置是非常重要的，这样就可以根据写到数据库中的数据，以及提供一个管理后台来操作网关的配置了，在网关启动的时候从数据库读取数据来动态实例化所有的配置内容。 + +### 3. 测试验证 + +启动服务后，访问地址：`curl http://localhost:8090/gw/api/user/hi`、`curl http://localhost:8090/error` + +

+ +
+ +工程结构分为2个部分： +- app 启动层的 config 包下，用于提供 Zookeeper 服务的启动配置。以及小傅哥在这里新添加的功能 DCCValue 配置中心模块。 +- trigger 是触发器，这里吧 http 请求、listener 监听，都是放到这里使用。另外像 MQ、JOB、RPC 也是放到这一层，以这一层触发，来调用我们的领域服务。 + +### 2. 启动 Zookeeper 服务 + +#### 2.1 自定配置 + +```java +@Data +@ConfigurationProperties(prefix = "zookeeper.sdk.config", ignoreInvalidFields = true) +public class ZookeeperClientConfigProperties { + + private String connectString; + private int baseSleepTimeMs; + private int maxRetries; + private int sessionTimeoutMs; + private int connectionTimeoutMs; + +} +``` + +#### 2.2 使用配置 + +```xml +zookeeper: + sdk: + config: + connect-string: 10.253.6.71:2181 + base-sleep-time-ms: 1000 + max-retries: 3 + session-timeout-ms: 1800000 + connection-timeout-ms: 30000 +``` + +#### 2.3 配置服务 + +```java +@Configuration +@EnableConfigurationProperties(ZookeeperClientConfigProperties.class) +public class ZooKeeperClientConfig { + + /** + * 多参数构建ZooKeeper客户端连接 + * + * @return client + */ + @Bean(name = "zookeeperClient") + public CuratorFramework createWithOptions(ZookeeperClientConfigProperties properties) { + ExponentialBackoffRetry backoffRetry = new ExponentialBackoffRetry(properties.getBaseSleepTimeMs(), properties.getMaxRetries()); + CuratorFramework client = CuratorFrameworkFactory.builder() + .connectString(properties.getConnectString()) + .retryPolicy(backoffRetry) + .sessionTimeoutMs(properties.getSessionTimeoutMs()) + .connectionTimeoutMs(properties.getConnectionTimeoutMs()) + .build(); + client.start(); + return client; + } + +} +``` + +- 这样我们就可以启动一个 Zookeeper 的客户端了，自定义可以更好的控制和使用。 + +### 3. 定义注解 + +就功能来讲，我们需要对类中的属性进行赋值操作。那么就需要使用自定义注解进行标记。所以这里我们先自定义一个注解。 + +```java +@Retention(RetentionPolicy.RUNTIME) +@Target({ElementType.FIELD}) +@Documented +public @interface DCCValue { + + String value() default ""; + +} +``` + +- 这样所有使用了 `@DCCValue` 的注解的字段就都可以被我扫描到了。 + +### 4. 监听变化 + +#### 4.1 获取属性 + +**源码**：`cn.bugstack.xfg.dev.tech.config.DCCValueBeanFactory#postProcessAfterInitialization` + +```java +@Override +public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { + Class beanClass = bean.getClass(); + Field[] fields = beanClass.getDeclaredFields(); + for (Field field : fields) { + if (field.isAnnotationPresent(DCCValue.class)) { + DCCValue dccValue = field.getAnnotation(DCCValue.class); + try { + if (null == client.checkExists().forPath(BASE_CONFIG_PATH.concat("/").concat(dccValue.value()))) { + client.create().creatingParentsIfNeeded().forPath(BASE_CONFIG_PATH.concat("/").concat(dccValue.value())); + log.info("DCC 节点监听 listener node {} not absent create new done!", BASE_CONFIG_PATH.concat("/").concat(dccValue.value())); + } + } catch (Exception e) { + throw new RuntimeException(e); + } + dccObjGroup.put(BASE_CONFIG_PATH.concat("/").concat(dccValue.value()), bean); + } + } + return bean; +} +``` + +- DCCValueBeanFactory 实现了 BeanPostProcessor 接口的 postProcessAfterInitialization 方法。 +- 在实现中，通过对 bean 对象的解析获取到使用 DCCValue 注解属性，并判断这个属性拼接的地址是否在 Zookeeper 中创建，如果没有则创建。之后保存对象到内存中。 + +#### 4.2 设置属性 + +**源码**：`cn.bugstack.xfg.dev.tech.config.DCCValueBeanFactory#DCCValueBeanFactory` + +```java +curatorCache.listenable().addListener((type, oldData, data) -> { + switch (type) { + case NODE_CHANGED: + String dccValuePath = data.getPath(); + Object objBean = dccObjGroup.get(dccValuePath); + try { + // 1. getDeclaredField 方法用于获取指定类中声明的所有字段，包括私有字段、受保护字段和公共字段。 + // 2. getField 方法用于获取指定类中的公共字段，即只能获取到公共访问修饰符（public）的字段。 + Field field = objBean.getClass().getDeclaredField(dccValuePath.substring(dccValuePath.lastIndexOf("/") + 1)); + field.setAccessible(true); + field.set(objBean, new String(data.getData())); + field.setAccessible(false); + } catch (Exception e) { + throw new RuntimeException(e); + } + break; + default: + break; + } +}); +``` + +- 基于 Zookeeper 对节点的监听，只要这个节点上有值发生变化。就可以立刻检测到对应的路径信息和值信息。 +- 那么拿到这个值信息，就可以把值写入到对应的属性上了。如`类.A = Zookeeper 获取到的值` + +## 五、功能使用 + +**源码**：`cn.bugstack.xfg.dev.tech.trigger.http.ConfigController` + +```java +@RestController +public class ConfigController { + + @DCCValue("downgradeSwitch") + private String downgradeSwitch; + + @DCCValue("userWhiteList") + private String userWhiteList; + + @Resource + private CuratorFramework curatorFramework; + + /** + * curl http://localhost:8091/getConfig/downgradeSwitch + */ + @RequestMapping("/getConfig/downgradeSwitch") + public String getConfigDowngradeSwitch() { + return downgradeSwitch; + } + + /** + * curl http://localhost:8091/getConfig/userWhiteList + */ + @RequestMapping("/getConfig/userWhiteList") + public String getConfigUserWhiteList() { + return userWhiteList; + } + + /** + * curl -X GET "http://localhost:8091/setConfig?downgradeSwitch=false&userWhiteList=xfg,user2,user3" + */ + @GetMapping("/setConfig") + public void setConfig(Boolean downgradeSwitch, String userWhiteList) throws Exception { + curatorFramework.setData().forPath("/xfg-dev-tech/config/downgradeSwitch", (downgradeSwitch ? "开" : "关").getBytes(StandardCharsets.UTF_8)); + curatorFramework.setData().forPath("/xfg-dev-tech/config/userWhiteList", userWhiteList.getBytes(StandardCharsets.UTF_8)); + } + +} +``` + +这里的核心验证就是让 downgradeSwitch、userWhiteList 这2个属性值可以动态变化； +1. 在两个属性上添加注解后，就会被扫描和管理。 +2. 获取值方法：[http://localhost:8091/getConfig/downgradeSwitch](http://localhost:8091/getConfig/downgradeSwitch)、[http://localhost:8091/getConfig/userWhiteList](http://localhost:8091/getConfig/userWhiteList) +3. 设置值方法：[http://localhost:8091/setConfig?downgradeSwitch=false&userWhiteList=xfg,user2,user3](http://localhost:8091/setConfig?downgradeSwitch=false&userWhiteList=xfg,user2,user3) - `这里的设置值操作不非得在这里，可以是一个单独的控制后台来操作。这里的方式主要是演示作用` + +
+ +
+ +你可以按照如图的操作顺序，进行验证属性值的变化。 + +## 六、其他测试 + +```java +@Slf4j +@RunWith(SpringRunner.class) +@SpringBootTest +public class ApiTest { + + @Resource + private CuratorFramework curatorFramework; + + @Test

容器的实现类中要重点关注类之间的职责和关系，几乎所有的程序功能设计都离不开接口、抽象类、实现、继承，而这些不同特性类的使用就可以非常好的隔离开类的功能职责和作用范围。而这样的知识点也是在学习手写 Spring Bean 容器框架过程非常重要的知识。 -

Spring 框架组建提供的容器扩展机制，允许在 Bean 对象注册后但未实例化之前，对 Bean 的定义信息 `BeanDefinition` 执行修改操作。 - BeanPostProcessor，也是 Spring 提供的扩展机制，不过 BeanPostProcessor 是在 Bean 对象实例化之后修改 Bean 对象，也可以替换 Bean 对象。这部分与后面要实现的 AOP 有着密切的关系。 - 同时如果只是添加这两个接口，不做任何包装，那么对于使用者来说还是非常麻烦的。我们希望于开发 Spring 的上下文操作类，把相应的 XML 加载 、注册、实例化以及新增的修改和扩展都融合进去，让 Spring 可以自动扫描到我们的新增服务，便于用户使用。 @@ -656,4 +656,14 @@ Process finished with exit code 0 ##

框架的设计，用于解决循环依赖需要用到三个缓存，这三个缓存分别存放了`成品对象`、`半成品对象(未填充属性值)`、`代理对象`，分阶段存放对象内容，来解决循环依赖问题。 + +**那么**，这里我们需要知道一个核心的原理，就是用于解决循环依赖就必须是三级缓存呢，二级行吗？一级可以不？其实都能解决，只不过 Spring 框架的实现要保证几个事情，如只有一级缓存处理流程没法拆分，复杂度也会增加，同时半成品对象可能会有空指针异常。而将半成品与成品对象分开，处理起来也更加优雅、简单、易扩展。另外 Spring 的两大特性中不仅有 IOC 还有 AOP，也就是基于字节码增强后的方法，该存放到哪，而三级缓存最主要，要解决的循环依赖就是对 AOP 的处理，但如果把 AOP 代理对象的创建提前，那么二级缓存也一样可以解决。但是，这就违背了 Spring 创建对象的原则，Spring 更喜欢把所有的普通 Bean 都初始化完成，在处理代理对象的初始化。 + +**不过**，没关系我们可以先尝试仅适用一级缓存来解决循环依赖，通过这样的方式从中学习到处理循环依赖的最核心原来，也就是那20%的地方。 + +![](https://bugstack.cn/assets/images/spring/spring-17-02.png) + +- 如果仅以一级缓存解决循环依赖，那么在实现上可以通过在A对象 newInstance 创建且未填充属性后，直接放入缓存中。 +- 在`A对象`的属性填充`B对象`时，如果缓存中不能获取到`B对象`，则开始创建`B对象`，同样创建完成后，把`B对象`填充到缓存中去。 +- 接下来就开始对`B对象`的属性进行填充，恰好这会可以从缓存中拿到`半成品的A对象`，那么这个时候`B对象`的属性就填充完了。 +- 最后返回来继续完成`A对象`的属性填充，把实例化后并填充了属性的`B对象`赋值给A对象的`b属性`，这样就完成了一个循环依赖操作。 + +**代码实现** + +```java +private final static Map singletonObjects = new ConcurrentHashMap<>(256); + +private static T getBean(Class beanClass) throws Exception { + String beanName = beanClass.getSimpleName().toLowerCase(); + if (singletonObjects.containsKey(beanName)) { + return (T) singletonObjects.get(beanName); + } + // 实例化对象入缓存 + Object obj = beanClass.newInstance(); + singletonObjects.put(beanName, obj); + // 属性填充补全对象 + Field[] fields = obj.getClass().getDeclaredFields(); + for (Field field : fields) { + field.setAccessible(true); + Class fieldClass = field.getType(); + String fieldBeanName = fieldClass.getSimpleName().toLowerCase(); + field.set(obj, singletonObjects.containsKey(fieldBeanName) ? singletonObjects.get(fieldBeanName) : getBean(fieldClass)); + field.setAccessible(false); + } + return (T) obj; +} +``` + +- 使用一级缓存存放对象的方式，就是这样简单的实现过程，只要是创建完对象，立马塞到缓存里去。这样就可以在其他对象创建时候获取到属性需要填充的对象了。 + +**测试结果** + +```java +public static void main(String[] args) throws Exception { + System.out.println(getBean(B.class).getA()); + System.out.println(getBean(A.class).getB()); +} + +cn.bugstack.springframework.test.A@49476842 +cn.bugstack.springframework.test.B@78308db1 + +Process finished with exit code 0 +``` + +![](https://bugstack.cn/assets/images/spring/spring-17-03.png) + +- 从测试效果和截图依赖过程中可以看到，一级缓存也可以解决简单场景的循环依赖问题。 +- 其实 `getBean`，是整个解决循环依赖的核心内容，A 创建后填充属性时依赖 B，那么就去创建 B，在创建 B 开始填充时发现依赖于 A，但此时 A 这个半成品对象已经存放在缓存到`singletonObjects` 中了，所以 B 可以正常创建，在通过递归把 A 也创建完整了。 + +--- + +有了以上这部分关于循环依赖的处理内容，在理解循环依赖就没那么复杂了。接下来我们带着这个`感觉`去思考如果有对象不只是简单的对象，还有代理对象，还有AOP应用，要怎么处理这样的依赖问题。整体设计结构如下图： + +![](https://bugstack.cn/assets/images/spring/spring-17-04.png) + +- 关于循环依赖在我们目前的 Spring 框架中扩展起来也并不会太复杂，主要就是对于创建对象的`提前暴露`，如果是工厂对象则会使用 getEarlyBeanReference 逻辑提前将工厂🏭对象存放到三级缓存中。等到后续获取对象的时候实际拿到的是工厂对象中 getObject，这个才是最终的实际对象。 +- 在创建对象的 `AbstractAutowireCapableBeanFactory#doCreateBean` 方法中，提前暴露对象以后，就可以通过接下来的流程，getSingleton 从三个缓存中以此寻找对象，一级、二级如果有则直接取走，如果对象是三级缓存中则会从三级缓存中获取后并删掉工厂对象，把实际对象放到二级缓存中。 +- 最后是关于单例的对象的注册操作，这个注册操作就是把真实的实际对象放到一级缓存中，因为此时它已经是一个成品对象了。 + +## 四、实现 + +### 1. 工程结构 + +```java +small-spring-step-16 +└── src + ├── main + │ └── java + │ └── cn.bugstack.springframework + │ ├── aop + │

提供三级缓存：`singletonObjects`、`earlySingletonObjects`、`singletonFactories`，分别存放成品对象、半成品对象和工厂对象。同时包装三个缓存提供方法：getSingleton、registerSingleton、addSingletonFactory，这样使用方就可以分别在不同时间段存放和获取对应的对象了。 +- 在 AbstractAutowireCapableBeanFactory 的 doCreateBean 方法中，提供了关于提前暴露对象的操作，`addSingletonFactory(beanName, () -> getEarlyBeanReference(beanName, beanDefinition, finalBean));`，以及后续获取对象和注册对象的操作，` exposedObject = getSingleton(beanName);`、`registerSingleton(beanName, exposedObject);`，经过这样的处理就可以完成对复杂场景循环依赖的操作。 +- 另外在 DefaultAdvisorAutoProxyCreator 提供的切面服务中，也需要实现接口 InstantiationAwareBeanPostProcessor 新增的 getEarlyBeanReference 方法，便于把依赖的切面对象也能存放到三级缓存中，处理对应的循环依赖。 + +### 2. 设置三级缓存 + +**cn.bugstack.springframework.beans.factory.support.DefaultSingletonBeanRegistry** + +```java +public class

public Object getSingleton(String beanName) { + Object singletonObject = singletonObjects.get(beanName); + if (null == singletonObject) { + singletonObject = earlySingletonObjects.get(beanName); + //

disposableBeans.put(beanName, bean); + } + +} +``` + +- 在用于提供单例对象注册的操作的 DefaultSingletonBeanRegistry 类中，共有三个缓存对象的属性；singletonObjects、earlySingletonObjects、singletonFactories，如它们的名字一样，用于存放不同类型的对象（单例对象、早期的半成品单例对象、单例工厂对象）。 +- 紧接着在这三个缓存对象下提供了获取、添加和注册不同对象的方法，包括：getSingleton、registerSingleton、addSingletonFactory，其实后面这两个方法都比较简单，主要是 getSingleton 的操作，它是在一层层处理不同时期的单例对象，直至拿到有效的对象。 + +### 3. 提前暴露对象 +

AbstractAutowireCapableBeanFactory#doCreateBean 的方法中主要是扩展了对象的提前暴露`addSingletonFactory`了，和单例对象的获取`getSingleton`以及注册操作`registerSingleton`。 +- 这里提到一点 getEarlyBeanReference 就是定义在如 AOP 切面中这样的代理对象，可以参考源码中接口 InstantiationAwareBeanPostProcessor#getEarlyBeanReference 方法的实现。 + +## 五、测试 + +因为是要测试循环依赖，我们找一个比较贴近的场景来做测试，*我说过我是一个喜欢从生活中发现面向对象编程的人* 我们的案例场景人物包括：老公和媳妇互相依赖、婆婆是一个模拟成代理妈妈职责、在加上一个切面来关心家庭生活👪 + +### 1. 事先准备

method); + } + +} +``` + +### 2. 属性配置文件 + +**spring.xml** + +```java + + + + + + + + + + + + + + + + + + + + + + + + +``` + +- 这个里的配置就很简单了，配置husband依赖wife，配置wife依赖husband和mother，最后是关于AOP切面的依赖使用。 + +### 3. 单元测试 + +```java +@Test +public void test_circular() { + ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring.xml"); + Husband husband = applicationContext.getBean("husband", Husband.class); + Wife wife = applicationContext.getBean("wife", Wife.class); + System.out.println("老公的媳妇：" + husband.queryWife()); + System.out.println("媳妇的老公：" + wife.queryHusband()); +} +``` + +**测试结果** + +![](https://bugstack.cn/assets/images/spring/spring-17-06.png) + +```java +老公的媳妇：Husband.wife +关怀小两口(切面)：public java.lang.String

定义类型转换接口 + +**包：cn.bugstack.springframework.core.convert.converter** + +**类型转换处理接口** + +```java +public interface Converter { + + /** Convert the source object of type {@code S} to target type {@code T}. */ + T convert(S source); + +} +``` + +**类型转换工厂** + +```java +public interface ConverterFactory{ + + /** + * Get the converter to convert from S to target type T, where T is also an instance of R. + * @param the target type + * @param targetType the target type to convert to + * @return a converter from S to T + */ + Converter getConverter(Class targetType); + +} +``` + +**类型转换注册接口** + +```java +public interface ConverterRegistry { + + /** + * Add a plain converter to this registry. + * The convertible source/target type pair is derived from the Converter's parameterized types. + * @throws IllegalArgumentException if the parameterized types could not be resolved + */ + void addConverter(Converter converter); + + /** + * Add a generic converter to this registry. + */ + void addConverter(GenericConverter converter); + + /** + * Add a ranged converter factory to this registry. + * The convertible source/target type pair is derived from the ConverterFactory's parameterized types. + * @throws IllegalArgumentException if the parameterized types could not be resolved + */ + void addConverterFactory(ConverterFactory converterFactory); + +} +``` + +- Converter、ConverterFactory、ConverterRegistry，都是用于定义类型转换操作的相关接口，后续所有的实现都需要围绕这些接口来实现，具体的代码功能可以进行调试验证。 + +### 3. 实现类型转换服务 + +**cn.bugstack.springframework.core.convert.support.DefaultConversionService** + +```java +public class DefaultConversionService extends GenericConversionService{ + + public DefaultConversionService() { + addDefaultConverters(this); + } + + public static void addDefaultConverters(ConverterRegistry converterRegistry) { + // 添加各类类型转换工厂 + converterRegistry.addConverterFactory(new StringToNumberConverterFactory()); + } + +} +``` + +- DefaultConversionService 是继承 GenericConversionService 的实现类，而 GenericConversionService 实现了 ConversionService, ConverterRegistry 两个接口，用于 canConvert 判断和转换接口 convert 操作。 + +### 4. 创建类型转换工厂 + +**cn.bugstack.springframework.context.support.ConversionServiceFactoryBean** + +```java +public class ConversionServiceFactoryBean implements FactoryBean, InitializingBean { + + @Nullable + private Set converters; + + @Nullable + private GenericConversionService conversionService; + + @Override + public ConversionService getObject() throws Exception { + return conversionService; + } + + @Override + public Class getObjectType() { + return conversionService.getClass(); + } + + @Override + public boolean isSingleton() { + return true; + } + + @Override + public void afterPropertiesSet() throws Exception { + this.conversionService = new DefaultConversionService(); + registerConverters(converters, conversionService); + } + + private void registerConverters(Set converters, ConverterRegistry registry) { + if (converters != null) { + for (Object converter : converters) { + if (converter instanceof GenericConverter) { + registry.addConverter((GenericConverter) converter); + } else if (converter instanceof Converter) { + registry.addConverter((Converter) converter); + } else if (converter instanceof ConverterFactory) { + registry.addConverterFactory((ConverterFactory) converter); + } else { + throw new IllegalArgumentException("Each converter object must implement one of the " + + "Converter, ConverterFactory, or GenericConverter interfaces"); + } + } + } + } + + public void setConverters(Set converters) { + this.converters = converters; + } + +} +``` + +- 有了 FactoryBean 的实现就可以完成工程对象的操作，可以提供出转换对象的服务 GenericConversionService，另外在 afterPropertiesSet 中调用了注册转换操作的类。最终这个类会被配置到 spring.xml 中在启动的过程加载。 + +### 5. 类型转换服务使用 + +**cn.bugstack.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory** + +```java +protected void applyPropertyValues(String beanName, Object bean, BeanDefinition beanDefinition) { + try { + PropertyValues propertyValues = beanDefinition.getPropertyValues(); + for (PropertyValue propertyValue : propertyValues.getPropertyValues()) { + String name = propertyValue.getName(); + Object value = propertyValue.getValue(); + if (value instanceof BeanReference) { + // A 依赖 B，获取 B 的实例化 + BeanReference beanReference = (BeanReference) value; + value = getBean(beanReference.getBeanName()); + } + // 类型转换 + else { + Class sourceType = value.getClass(); + Class targetType = (Class) TypeUtil.getFieldType(bean.getClass(), name); + ConversionService conversionService = getConversionService(); + if (conversionService != null) { + if (conversionService.canConvert(sourceType, targetType)) { + value = conversionService.convert(value, targetType); + } + } + } + // 反射设置属性填充 + BeanUtil.setFieldValue(bean, name, value); + } + } catch (Exception e) { + throw new BeansException("Error setting property values：" + beanName + " message：" + e); + } +} +``` + +- 在 AbstractAutowireCapableBeanFactory#applyPropertyValues 填充属性的操作中，具体使用了类型转换的功能。 +- 在 AutowiredAnnotationBeanPostProcessor#postProcessPropertyValues 也有同样的属性类型转换操作。 + +## 五、测试 + +### 1. 事先准备 + +```java +public class Husband { + + private String wifiName; + + private Date marriageDate; // 添加一个日期类的转换操作 + + // ... get/set +} +``` + +**转换时间的操作类** + +```java +public class StringToLocalDateConverter implements Converter { + + private final DateTimeFormatter DATE_TIME_FORMATTER; + + public StringToLocalDateConverter(String pattern) { + DATE_TIME_FORMATTER = DateTimeFormatter.ofPattern(pattern); + } + + @Override + public LocalDate convert(String source) { + return LocalDate.parse(source, DATE_TIME_FORMATTER); + } + +} +``` + +- Husband 是一个基础对象类设置了时间属性，之后再添加一个类型转换的操作用于转换时间信息。 + +### 2. 属性配置文件 + +**spring.xml** + +```xml + + + + + + + + + + +``` + +- 配置基础Bean对象，设置属性的日期，同时再添加类型转换的服务和自己实现的 `ConvertersFactoryBean` + +### 3. 单元测试 + +```java +@Test +public void test_convert() { + ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring.xml"); + Husband husband = applicationContext.getBean("husband", Husband.class); + System.out.println("测试结果：" + husband); +} + +@Test +public void test_StringToIntegerConverter() { + StringToIntegerConverter converter = new StringToIntegerConverter(); + Integer num = converter.convert("1234"); + System.out.println("测试结果：" + num); +} + +@Test +public void test_StringToNumberConverterFactory() { + StringToNumberConverterFactory converterFactory = new StringToNumberConverterFactory(); + Converter stringToIntegerConverter = converterFactory.getConverter(Integer.class); + System.out.println("测试结果：" + stringToIntegerConverter.convert("1234")); + Converter stringToLongConverter = converterFactory.getConverter(Long.class); + System.out.println("测试结果：" + stringToLongConverter.convert("1234")); +} +``` + +**测试结果** + +```java +测试结果：Husband{wifiName='你猜', marriageDate=Sun Aug 08 00:00:00 CST 2021} + +Process finished with exit code 0 +``` + +- 这个测试内容还是比较简单的，可以自行验证结果，虽然最终的结果看上去比较简单，但整个框架结构实现设计还是蛮复杂的，把这么一个转换操作抽象为接口适配、工厂模型等方式，还是很值得借鉴的。 + +## 六、总结 + +- 本章节实现的类型转换操作如果只是功能性的开发，就像你自己承接的需求那样，可能只是简单的if判断就搞定了，但放在一个成熟的框架要中要考虑的是可复用性、可扩展性，所以会看到接口的定义、工厂的使用等等设计模式在这里体现。 +- 最后非常感谢你能坚持学习到这个章节，如果你在学习的过程也是每一个章节都是对着文章、写着代码代码、调试着bug，感悟着设计，那么你一定会在这个过程中得到很多很多，以后再阅读Spring的源码也就不会感觉那么难了。 -- [类型转换机制设计 @Rechie](https://t.zsxq.com/06jiAub2n) \ No newline at end of file diff --git

+ +
+ +欢迎来到这里，很高兴你`将`拿到这本电子书，如果你能坚持看完并按照书中的例子进行实践，那么在编程开发的世界里，就又多了一个可以写出良好代码的人，同时也为架构师培养储备了一个人才。 + +可能在此之前你也多少了解过设计模式，但在实际的业务开发中使用却不多，多数时候都是大面积堆积`ifelse`组装业务流程，对于一次次的需求迭代和逻辑补充，只能东拼西凑`Ctrl+C`、`Ctrl+V`。 + +所以为了能让更多的程序员👨‍💻‍更好的接受设计思想和架构思维，并能运用到实际的业务场景。本书的作者`小傅哥`，投入50天时间，从互联网实际业务开发中抽离出，交易、营销、秒杀、中间件、源码等22个真实场景，来学习设计模式实践使用的应用可上手技能。 + +### 1. 谁发明了设计模式？ + +设计模式的概念最早是由 `克里斯托佛·亚历山大` 在其著作 `《建筑模式语言》` 中首次提出的。 本书介绍了城市设计的 “语言”，提供了253个描述城镇、邻里、住宅、花园、房间及西部构造的模式， 而此类 “语言” 的基本单元就是模式。后来，`埃里希·伽玛`、 `约翰·弗利赛德斯`、 `拉尔夫·约翰逊` 和 `理查德·赫尔姆` 这四位作者接受了模式的概念。 1994 年， 他们出版了 `《设计模式： 可复用面向对象软件的基础》` 一书， 将设计模式的概念应用到程序开发领域中。 + +其实有一部分人并没有仔细阅读过设计模式的相关书籍和资料，但依旧可以编写出优秀的代码。这主要是由于在经过众多项目的锤炼和对程序设计的不断追求，从而在多年编程历程上提炼出来的心得体会。而这份经验最终会与设计模式提到的内容几乎一致，同样会要求高内聚、低耦合、可扩展、可复用。你可能也遇到类似的经历，在学习一些框架的源码时，发现它里的某些设计和你在做开发时一样。 + +### 2. 我怎么学不会设计模式？ + +钱也花了，书也买了。代码还是一坨一坨的！设计模式是由多年的经验提炼出来开发指导思想。就像我告诉你自行车怎么骑、汽车怎么开，但只要你没跑过几千公里，你能记住的只是理论，想上道依旧很慌！ + +**所以**，本设计模式专题系列开始，会带着你使用设计模式的思想去优化代码。从而学习设计模式的心得并融入给自己。当然这里还需要多加练习，一定是*人车合一*，才能站在设计模式的基础上构建出更加合理的代码。 + +### 3. 适合人群 + +1. 具备一定编程基础在工作1-3年的研发人员 +2. 希望通过此书提升编码思维，剔除到代码中的坏味道 +3. 有意愿成为架构师，但还处在一定瓶颈期 +4. 学习过设计模式，可是一直想找到一本可以落地真实场景参照的书籍 + +### 4. 我能学到什么 + +1. 优化平时开发中的ifelse语句，让代码更加整洁 +2. 看设计模式不再是用理论生搬硬套，这次可以有点用 +3. 站在更高的角度去看待编程开发，学会更多的面向对象的思维，尤其是；接口、抽象类、多态等使用 +4. 升职、加薪，良好的代码是效能提升的基础，成为本组编码最靓的精神小伙 + +### 5. 阅读建议 + +本书属于实战型而不是理论介绍类书籍，每一章节都有对应的完整代码，学习的过程需要参考书中的章节与代码一起学习，同时在学习的过程中需要了解并运行代码。学习完成后进行知识点的总结，以及思考🤔这样的设计模式在自己的业务场景中需要如何使用。 + +## 三、书中目录 + +设计模式遵循六大原则；单一职责(`一个类和方法只做一件事`)、里氏替换(`多态，子类可扩展父类`)、依赖倒置(`细节依赖抽象，下层依赖上层`)、接口隔离(`建立单一接口`)、迪米特原则(`最少知道，降低耦合`)、开闭原则(`抽象架构，扩展实现`)，会在具体的设计模式章节中，进行体现。 + +### 1. 创建型模式 + +**这类模式提供创建对象的机制， 能够提升已有代码的灵活性和可复用性。**

+ +
+ +**注意**：小傅哥的星球，已经形成了一个技术矩阵。不是一个单独的项目教程，而是成体系化的学习成长。 + +说实话写了这么多各类型的项目，确实花费了我好多的精力，在这个过程也耐得住了不少的诱惑。我没有去蹭各类热点和软文、也没有追逐营销和广告，而是花费了2~3年的时间，打磨这些课程项目。形成业务、技术、组件的多种类型项目组合，对比不同类型架构和思维的落地，综合锻炼各项技术栈的实践使用。只要你能完整的跟着学习下来，就能开阔自己的技术视野和积累不错的技术厚度。 + +
+ +
+ +那么，这些项目对于处在不同阶段的伙伴；实习、校招、社招，要从哪个开始学呢？接下来小傅哥就重点的介绍下项目的重点和学习的路线。 + +>文末有加入学习方式，小傅哥编写的所有项目和资料，只要加入就都可以学习。 + +## 一、项目视图 + +接下来小傅哥把星球已有的项目类课程平铺展开，对比项目的`难度`、`介绍`、`系统的架构`以及`运用到的技术栈`。这些内容的对比，对于需要学习项目的伙伴非常重要，可以针对性的选择有需要的课程内容补充自己的技术欠缺。 + +
+ +
+ +前四个，为业务类型的项目。后3个位技术类型的项目。 + +业务类项目，主要解决场景化的业务流程为主，运用架构、设计原则、设计模式，开发出便于迭代和易于维护的工程代码。现在越来越多的大厂开始重视工程质量，因为草莽时代的开发之追求快速上线，但存量市场的竞争，会更要求体验、稳定、可靠、成本。所以不能一个需求的开发就一堆的问题需要处理。 + +而一般技术类型的都以开发框架、组件、插件为主，用于解决公司项目组中同类共性功能的凝练，减少重复建设问题。一般会有人说不要重复造轮子，但往往面试时又会提到你是否能具备这样的深度组件设计开发落地能力。所以学习的过程是什么？我认为是多方面场景的锻炼，综合提升自身综合实力为主。让自己具备竞争力才是王道！ + +## 二、学习路线 + +小傅哥深知，所处不通阶段的伙伴，对于学习的诉求也是不一样的。`着急找实习的`、`稳扎卷春招的`、`拓展肝深度的`，大家都有着自己当前阶段的目标。所以小傅哥基于大家的诉求来划分出不同的学习路线，让各位有个选择的参考。 + +- 路线A：简单一些，能较快周期完成，偏速成类 +- 路线B：复杂一些，要较长周期完成，竞争力强 + +
+ +
+ +整个学习的时间周期消耗，是小傅哥平局下来偏基础较弱的学习耗时。如果你基础积累较多，那么完成的更快。接下来，重点在讲下，实习、校招、社招，学习的路线说明。 + +### 1. 实习生 + +在实习生路线中，提供了A、B两条路线； + +- A路线，打一个IM、Netty、OpenAi综合技术使用。如果IM部分不手动编码UI部分，预计可2周完成。对接OpenAi预计需要2-3天左右。整体耗时，3~5周时间。 +- B路线，稳扎稳打路线，DDD架构、分布式技术栈、多场景设计实现的项目。同时配合一个SpringBoot Starter组件，非常亮眼【AOP切面使用，对实习生来说很好】。整体耗时，4~7周时间，适合早点加入星球就开始学习的伙伴。 + +### 2. 校招生 + +在校招生路线中，提供了A、B两条路线； + +与简单一些的实习面试相比，应届校招的竞争会更强一些。所以两条路线都有分布式技术栈的学习，也建议简历中有2个项目再加一个你的实习项目，来应对校招。如果你没有实习过，那么最好完成2个项目。 + +- A路线，综合分布式技术栈的双场景实战，一个C端的运营类场景，另外一个是结合OpenAi做；鉴权登录、下单、支付(微信)、充值、消耗。这2个项目会让你面试的时候，非常有场景可以讲。 +- B路线，难度较大，除了一个业务项目，还增加了一个纯技术类项目。API网关。这个项目的难度是5星，非常有挑战。你会吸收到很多高级的编码和高级架构的设计思路。比较适合之前有不错的技术积累的伙伴选择。 + +### 3. 社招生 + +到社招开始，远不是实习、校招时，有那么多大门敞开。虽然都说校招卷，但也有个卷的途径。 + +社招的卷是无形的，每错过一个年龄段的职业生涯成长，就需要很多时间弥补。尤其是我们所在行业的这趟列车，所在的年龄达不到对应的岗位，就有可能会被动下车。虽然领导可能会给你1次、2次、3次的晋升机会，但如果都错过后面的路就会比较难走了。 + +所以，破解之法是广度&深度的积累自己的综合实力，让自己技术所长，远超公司所需。所有的学习都不是为了公司所学，都是为了自己在各方面的积累。这样才有更多的跳槽、涨薪、议价机会。 + +那么，到这就不用纠结于学哪个，从哪个开始。陆续的都吸收给自己吧！ + +🧧 [点此领优惠券加入星球](https://bugstack.cn/md/zsxq/other/join.html) diff --git a/docs/md/zsxq/material/student-learn-line.md b/docs/md/zsxq/material/student-learn-line.md new file mode 100644 index 000000000..a6eef8e78 --- /dev/null +++ b/docs/md/zsxq/material/student-learn-line.md @@ -0,0 +1,122 @@ +--- +title: 路线：180天，小卡拉米 - 编程路线，学习计划！ +lock: no +--- + +# 路线：180天，小卡拉米 - 编程路线，学习计划！ + +作者：小傅哥 +

+ +**以上就是你参与180天学习计划后的一个最终简历效果举例。** 当你决定参与一个学习计划或做一个项目，锻炼自己的技术的时候，先问问自己；`这个项目有什么架构`、`这个项目解决了什么场景问题`、`这个项目运用了什么设计模式`、`这个项目的编码质量如何`、`这个项目与企业实战中的差距有多大`、`这个项目的编写者是否有足够的实力`等。如果每一样都没有，稀里糊涂的就做，那就是花时间坑自己！🤔 + +以下是**180天学习日历📅**中的一个应用级实战技术项目的设计和代码举例，可以作为你的学习参考，看看这套路线有多硬核； + +| 项目架构 | +|:-----:| +|

| + +说实话，有如此`清晰的架构设计`、有如此`规模的工程拆分`、有如此`运用的设计模式`，这样的实战项目，又是本身一个大厂架构师，所编码、写文档、录课程，其实真的不多。但这样的项目在小傅哥的星球【码农会锁】**已有6个** ！你可以想象，你加入这样的技术社群，所能学习到多少硬核的技术东西。 + +## 四、回本计划 - 拿捏傅哥！🤏 + +`累计180天`，也就是半年的时间都在学习，其实并不容易。为此小傅哥会为大家提供一个学习打卡，提高学习氛围。同时累计打卡180天的前100个用户，会送一本小傅哥出版的签名技术图书，留作纪念。这一本技术图书也就可以回本门票了！加油！**我在山峰⛰等你！** + +

博客：[https://bugstack.cn](https://bugstack.cn) + +> 沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家伙，我是技术UP主小傅哥。 + +这些年，为公司做招聘工作。在我手里筛过的简历，没有上万份也得有几千份了。一眼扫过去简历内容，基本就知道面试时的效果如何。所以，我所在的小组招聘效率还是蛮高的。🤔 那什么样的简历容易被面试官看中呢？ + +
+ +
+ +**筛简历，我们更喜欢什么项目？** + +不同的公司往往对简历筛选时的侧重点是不同的，这个和工作时长没关系。有些工作6~7年的伙伴，简历全部B端项目，但这个时候投递C端类业务基本是没法匹配的。所以我们无论是校招还是社招，都要积累一些和自己想去的公司匹配的项目。 + +而互联网公司，更喜欢；C端的、通用的、分布式、创新的，因为这些东西也是互联网公司日常最常用场景，招聘这样的伙伴进来也不会特别耗力的培训。如；`电商`、`支付`、`信贷`、`营销`、`组件`、`源码`、`本地生活`，这些都是非常喜欢拿的简历。拿到简历就是细节的面试了，所以写的这些项目再有吸引力的同时，还要保证流程的完整性，不要防空炮。因为面试是会对简历进行评价打分，其他部门面试也会看见历史记录。 + +像这样的项目，市面有很多 `CRUD 案例类型的`，`比较适合入门`，`但面试还有些不够`。 + +所以小傅哥这里为你准备好了由小傅哥一行行代码从0到1带着学习的实战项目，把大厂的架构&研发经验搬过来，让你掌握。这样你的简历的内容就会更加丰富且细腻了，面试也有很多场景解决方案讲出来。 + +
+ +
+ +> 小傅哥，会为你提供一个个对标企业应用级的实战项目，积累丰富经验。学习后嘎嘎乱杀！文末可以获取全部学习项目「视频、文档、代码」 + +## 一、项目规模 + +小傅哥社区，组织开发了非常多的实战项目，目前包括5个业务类型、7个组件类型。并且这些项目是可以部署上线运行的项目「[https://gaga.plus](https://gaga.plus) 」 也是面试过程中，面试官喜欢问的点：”你的项目上线了吗“？ + +

+ +
+ +- 首先，你可以按照你的面试时间，进行路线选择。如果是一个月突击学习去面试，可以选择5周的路线，按照3个方案选择一套组合项目学习。如果时间比较充裕，准备的比较早，那么就建议按照12周学习来冲，这样竞争力是更强的。 +- 之后，在学习的过程中，推荐以项目驱动学习，完成项目为导向。在这个过程中遇到不会的内容，可以从基础教程中补充。这些各类技术技术内容，小傅哥都已经在星球编写好了文档和录制了视频，你可以从0到1轻松上车学习。 + +## 三、简历模板 + +有好经历，有不错的项目，还需要一套上档次的描述方式，这样才能更加完美的展示出自己的实力！这里小傅哥给大家提供了一个描述经历的结构，这样写的简历会更好的突出自己的能力，提高筛选通过率。 + +
+ +
+ +- 首先，个人信息，可以突出下过往的经验积累，包括；在过往的XXX经历中，积累了XXX场景的经验，使个人具备了XXX方面不错的能力。同时兼具着对(技术/场景)的(喜好/热忱)，长期(学习/从事/钻研)某项技术，并做出了对应的(开源)(产品/服务/组件/插件)。此个人XXX发布到XXX市场以后，得到了用户(下载量/点赞量/使用数)的规模，获得了非常好的认可。地址：http://github.com/xxxx/xxxx +- 之后，描述个人`教育背景`、`实习/实践经历`、`专业技能`和项目的编写。专业技能，要注意描述顺序和内容量，不宜过多，但要把招聘中核心技术栈体现出来。紧接着到项目描述，这部分最好有1~2个业务项目 + 1个组件类型项目，这样的组合简历内容，还是非常好用的。 +- 最后，补充一个自我评价。把自己描述成有技术追求的、有团队精神、有奋斗品质的优秀好青年。 + diff --git

+ +初次之外还有手写Spring、手写MyBatis，和一套基础教程。基础教程可以让小白伙伴扎扎实实的学习 SpringBoot 应用的分布式技术栈使用。这套基础教程完全是小傅哥从0到1编写，紧密配合星球实战项目。把各项所需的东西都拆解为一个个独立的小案例，让大家学习起来更加容易。 + +## 二、学习路线 + +星球的项目比较多，我来帮你明确一个学习路线，可以作为参考。这个路线分为3个阶段，分别对应到实习、校招、社招不同的能力要求。一般卷王的视角是，实习卷校招能力，校招卷社招能力，社招卷全部能力！ + +
+ +
+ +- 就实习来说，基本要求是了解一部分分布式技术栈，完整运用常用技术栈做过项目开发。如果能交付上线会更好。 +- 从实习完成，在到校招难度会加大一些。简历最好有2个项目。可以是2个业务项目，或者2个业务+1个技术的组合。技术可以是组件或者手写源码类。 +- 最后是社招，社招可以摘取1、2阶段的实战项目，综合在学习下源码应用的项目，这样简历会更有的拼。尤其是那种本身自己业务实在没啥讲的，那么就可以做个API网关，这类项目没有啥业务属性，学习后也更容易写到简历。【不少校招也写了 API网关，冲到阿阿里、美团、字节，还是很好用的】 + +
+ +
+ +> 小傅哥星球的这些项目，是站在一个架构师的视角，培养新人的综合技术能力而设计的。所以建议，可以有计划的完成学习积累。每一个项目都有自己的架构特色和设计的技巧，学到手对自己的帮助都非常大。让你不只是一个CRUD仔，面试/述职，都更有东西可以讲出来。 + +## 三、加入学习 + +小傅哥是一个大厂的架构师，经常会带着伙伴们，卷这些实际场景中非常有必要的技术。也会带着伙伴实战项目，这些项目也都是来自于互联网大厂中真实的业务场景，所有学习这样的项目无论是实习、校招、社招，都是有非常强的竞争力。别人还在玩玩具，而你已经涨能力！ + +>这样的项目学习在小傅哥星球「码农会锁」有8个，每个都是从0到1开发并提供简历模板和面试题，并且还在继续开发，后续还将有更多！价格嘎嘎实惠，早点加入，早点提升自己。项目地址：[https://gaga.plus](https://gaga.plus) \ No newline at end of file diff --git a/docs/md/zsxq/memorabilia/biographical-notes.md b/docs/md/zsxq/memorabilia/biographical-notes.md new file mode 100644 index 000000000..18e85cfe6 --- /dev/null +++ b/docs/md/zsxq/memorabilia/biographical-notes.md @@ -0,0 +1,73 @@ +--- +title: 2023年7月25日，校招简历应该怎么写 +lock: need +--- + +# 2023年7月25日，校招简历应该怎么写 + +作者：小傅哥 +

+ +
+ +**项目不行，编码量还不够！** + +之所以遇到这些面试问题，就是因为很多伙伴从毕业🎓到工作，以及在工作中基本都没做过什么好项目。不是毕业前做了一堆CRUD流程的Demo项目，就是工作后组装API接口的。往往这些过程都是有连带关系的，因为起步做的项目弱，缺少技术的积累和技术视野的认知，所以面试中表现的不够强，导致最终找工作的坑也会差。 + +当然，聪明一些有想法的伙伴，肯定会想办法去找一些在大厂真实工作的架构师进行`"偷师"`。把来自中大厂的`业务经验`、`架构经验`、`编程思维`、`编码技巧`，学习下来在用于实践验证和增强简历竞争力。所以跟谁学习很重要！ + +**注意**：📢 你的有效代码量，与你的能力息息相关。尤其是代码中含架构设计、设计模式、高级编码、场景问题的指标量占比越高越好。当你的积累远超过这一阶段诉求时候，你的能力也会很容易匹配到工作岗位。 + +

+ +
+ +**好的简历，就是用不同的内容做举证，展示自己的技术实力** + +`点评`、`外卖`、`电商/售票`，不少小傅哥的粉丝伙伴都做过这些项目，这些内容可以帮助大家快速的入门编程，也是非常不错的学习资料。在5年前，写这么任意一份项目内容，都可以成为那个时期的Offer收割机了。但现在的简历大部分都是相似模板的内容描述，筛选简历的时候拉不开差距。不过往往坏事和好事是相对的，大部分的都一样的时候，只要有人做出差异化，就会非常亮眼。 + +接下来，小傅哥就告诉你怎么做差异化，让你的简历脱颖而出！ + +## 一、组合技巧 + +>写简历就跟排兵布阵打仗一样，要搭配不同的兵种进行作战。 + +首先大家面试的目标是进入到职场，那么你的简历中项目内容和结构，越贴合于公司的标准，在筛选和面试中都是非常占优势的。那么在公司中是这样的，业务项目会包括；`用户`、`账户`、`信贷`、`商品库`、`交易`、`营销`（`积分、玩法、活动、券包、抽奖`）、`结算`、`清分`、`台账`、`收银台`等，之后是各个业务组里还会做一些所谓的轮子，这些轮子既不是运维类的，也不是组件里的，就单纯是为了解决同类共性的业务问题所做的开发，如；对接很多支付方，会提供自己的支付SDK来聚合支付。有自身的众多业务一致性监控，会有最终的环路/旁路监控系统。 + +那这你就知道了，如果你做的是外卖或者点评或者其他的主业务流程项目，他们都属于业务系统的一部分，之后所有的这些项目都可以配合营销项目。比如 `外卖 + 抽奖`、`点评 + 抽奖`、`支付完成 + 抽奖`，把这些项目组合起来使用，建立一个衔接性。这样在看下简历内容的整体排布。 + +
+ +
+ +- 四方面内容；积累展示、专业技能、业务项目、技术项目。 +- 看过有一些比较机智的伙伴，会在个人信息下面用2行左右的话术介绍出自己的能力。你不写这一句话，面试的时候也会让你做个自我介绍，那样突然的总结往往比较慌，说不来几句，就结束了。不如就提前写好，精炼话术写到简历上。 +- 之后是专业技能的覆盖度，不少简历这方面体现的是比较弱的，有的人全写精通，有的人全写了解，或者写的内容和项目用到的不匹配/没覆盖到，以及写的内容和招聘的诉求不匹配。这块要注意，没用过的可以学习。 +- 业务项目，就是上面咱们提到的组合，之后组件项目是一个亮点。可以是一个1个牛的业务 + 1个组件，也可以是2个业务 + 1个组件。来搭配着写简历。如果感觉写的多了，可以把组件的项目，不单独写项目，只是写到个人的介绍中，或者融合到业务项目里去。 + +>有了这样的组合意识，你会知道学习的时候要对那些内容下手。也会有意识的补充自己的短板。 + +## 二、项目搭配 + +小傅哥的星球有10个项目，5个业务 + 5个技术，你可以组合的选择学习，搭配着写到简历。这些项目都是小傅哥花费大量的时间创作，每一个都有自己的特色和亮点，做这些内容不只是完成项目，还会学到；思想、架构、场景解决方案、设计模式运用、高级编程技巧等。 + +
+ +
+ +- 所有这些内容，**加入星球「码农会锁」**，全部解锁学习。并不断的持续加入新的内容。 +- 小白也能跟着学习，所有项目用到的内容，都已经被小傅哥单独拆解一个个小的技术案例，让大家学习补充（如图最下面部分，非常全面成体系）。 +- 在学习完项目编写简历投递的前，还可以把简历发出来，小傅哥会帮你做简历评审和指导。 + +## 三、加入学习 + +>我用工作10年+的经验告诉你，一个好的Offer起步，至少可以避免花费3年时间走弯路！ + +星球「码农会锁」的这种公司级别的实战项目，全程是需求分析、架构设计、几十张表的把控、众多场景设计模式的解决方案和高级编码的技巧运用，都是让你拉倒面试竞争力的资本。—— 当你不在做 CRUD 的 demo 项目，你会发现自己的技术是质的改变，提升的非常快！ + +在今年的面试中，星球帮助众多伙伴拿到`微信支付`、`京东科技`、`度小满`、`蚂蚁金服`、`Lazada（电商优惠营销）`、`快手`、`美团到店`等Offer，还有的校招生薪资最高年包到45w，这个级别已经超过工作4年-5年的伙伴了！如果学历那么高，但技术不错的，也能拿到中厂Offer。所以说，一个好的Offer起步，真的可以少走3年的弯路！ + +

+ +
+ +- 这是一套大营销系统的分布式架构设计图，从前端到负载，从服务治理到后端分布式技术栈体现，从应用到部署和监控的全体系展示。在这样一套系统架构中，你可以清楚的知道从前到后的流程、各项分布式技术栈的用途、整个系统的脉络关系。所以这样的一个图可以清晰的指导我们做系统的搭建。 +- `佛瑞德·布鲁克斯`在写作《人月神话》一书时提及：软件系统的架构是有关软件系统该作什么以及不该作什么的实体观点。这些观点应和软件的实现分开。架构师的角色是“观点的看守者”，确认系统中增加的部分是符合此架构，因此可以保有概念完整性 +- 另外程序员`马尔文·康威`在1967年论文发表了康威定律，其中提到一个组织开发的软件，其架构会反映其组织架构。佛瑞德·布鲁克斯在写作《人月神话》一书时，就在书上时提到此例子，命名为“康威定律”。 + +### 2. 四色建模图 + +如果系统是 DDD 开发的，还需要做四色建模。在使用 DDD 的标准对系统建模前，一堆人要先了解 DDD 的操作手段，这样才能让产品、研发、测试、运营等了解业务的伙伴，都能在同一个语言下完成系统建模。 + +- 蓝色 - 决策命令，是用户发起的行为动作，如；开始签到、开始抽奖、查看额度等。 +- 黄色 - 领域事件，过去时态描述。如；签到完成、抽奖完成、奖品发放完成。它所阐述的都是这个领域要完成的终态。 +- 粉色 - 外部系统，如你的系统需要调用外部的接口完成流程。 +- 红色 - 业务流程，用于串联决策命令到领域事件，所实现的业务流程。一些简单的场景则直接有决策命令到领域事件就可以了。 +- 绿色 - 只读模型，做一些读取数据的动作，没有写库的操作。 +- 棕色 - 领域对象，每个决策命令的发起，都是含有一个对应的领域对象。 + +
+ +
+ +- 系统建模后可以细分出系统开发中要实现的领域，包括；返利、活动、策略、奖品，兑换可以是单独的领域也可以合并到返利实现。 +- 具体的建模过程可以阅读 [《架构：DDD 领域驱动设计，战略、战术、战役，落地指引规范》](https://bugstack.cn/md/project/big-market/ddd.html) + +### 3. 设计模式图 + +设计模式是解耦系统流程非常重要的手段，通过设计模式把复杂的流程切割成可以被容易处理的执行单元，在通过设计模式的创建、行为、结构，三类模型完成执行动作的处理。 + +
+ +
+ +- 如图，这是一个规则树模型，解决的拼团中实际的场景业务。从根节点、开关节点、营销节点、人群节点，再到最终的正常和异常结束节点。每个节点分别处理自己的业务流程。 +- 你可以想象，如果没有这样的设计模式模型结构，那么在代码中，就是一个大方法中，一堆的逻辑编写，维护的成本是非常高的。 + +### 4. 源码解析图 + +各类的框架源码中有非常多的设计技巧，也有很多的架构思维模型。如大家常用的 MyBatis 框架，拆解后的设计，就可以看出有多少东西可以学习。 + +
+ +
+ +这是整个《手写 Mybatis》的全貌地图，小傅哥会带着大家逐步实现这里面的功能模块，分章节细化各个模块的实现流程，最终让读者实现出一个丰富、全面、细致的 ORM 框架。在学习的过程中，大家也可以参考这张图来对照手写的代码以及 Mybatis 的源码，这样更加有利于对 Mybatis 框架的理解。 + +## 我是小白怎么开始 + +我的学习伙伴有在校的，有实习的，有毕业的，大家处于不同阶段。所以，小傅哥花费近4年时间，以大厂晋级能力项的要求，拆分出14个项目，以不同难度方式从小白到大白，一路培养，直至成长为高端的码农！在这个过程，你不只是学习到了想法，还学习到了一整套方法论。 + +如图，这是一整套的实战项目学习进阶路线，从小白到大佬，全程视频手把手带着从0到1，一步步完成项目的设计、开发和上线。在整套内容学习过程中，小傅哥为你提供了非常好的技术交流社群，及时解决学习问题。还包括调试你的问题代码，带你快速🔜出坑！ + +

+ +
+ +- 2025年11月27日，Google 正式在 Maven 仓库管理中心，推送了 0.4.0 版本 ADK，该版本新增加了 Spring AI 的集成。[google-adk-spring-ai](https://central.sonatype.com/artifact/com.google.adk/google-adk-spring-ai) 至此，也因此，小傅哥决定基于这套服务组合，设计智能体脚手架。 +- 首先，Google ADK 是一个智能体框架，他自身也是支持直接对接各类大模型的 API，以及构建 ChatModel 的。但在整合 Spring AI、LangeChain4J 以后，Google ADK 的使用，将会得到已经使用上述组件的公司更大的青睐。 +- 之后，Spring AI 解决的 AI 对接的前半部分，让你可以把 AI API、Model、Prompt、RAG、Tool（Function、MCP）等，非常方便的构建出一个单一的 AI Agent 服务（也可以称之为是一个客户端）。 +- 然后，Google ADK 解决的是，多个 AI Agent 怎么协同工作的问题。这里包括，Sequential 序列顺序执行、Loop 循环执行、Parallel 并行执行，而这些执行方式，又可以组合搭配的配置到一个 Sequential 中进行顺序执行（注意图中颜色）。绿色的是大模型服务，绿色部分可以被深黄色或者浅青色包装，之后在组合到 SequentialAgent - 序列执行中。 +- 最后，Google ADK 提供了记忆上下文 Runner 执行器（也可以自己扩展实现），在这里又提供了钩子插件，你可以对执行过程中的流程，进行拦截。这个过程类似 Spring 容器中对 Bean 对象的处理，before、after 的过程。 + +### 2. 系统的分层结构 + +如图，整体简要架构设计（剥离其他流程，方便理解）； + +
+ +
+ +整个应用架构分为3层，包括；基础底座、脚手架、业务场景； + +- 基础底座，负责整 Spring AI + Google ADK 框架的使用，这里的重点在于整个智能体工作流程的设计和使用（第2部分20节课程）。 +- 脚手架，将基础底座使用 maven 抽取出脚手架，脚手架可以让我们快速复刻出一套基础工程（第3部分3节）。 +- 业务场景，结合 draw.io 绘图操作 + ai agent 智能体，做一套AI交互式画图系统（第4部分6节）。 + +### 3. 底座的运行流程 + +
+ +
+ +- 首先，从用户基于脚手架创建完成后，在使用 YML 文件进行智能体的配置，之后在启动项目后，会进行一些利的装配。api、model、agent、workflow、runner，再到 spring 容器。 +- 其中，关于智能体的工作流组装是非常巧妙的，可以自由组合出多种类型智能体。这部分不需要硬编码即可完成。 +- 最后，是整个内容装配完成后，提供了通用的接口能力可以进行对话。 + +### 4. 脚手架配置发布 + +
+ +
+ +- 左侧，对现有工程使用 maven-archetype-plugin 插件，构建工程脚手架。将当前的工程打包成一个可复用的 Archetype 模板。 +- 中间，打包好的脚手架，可以在本地直接使用，也可以发布jar到私服，让大家都可以使用。私服部分，后续在做处理。 +- 右侧，使用方可以基于命令，或者 IntelliJ IDEA 配置 Maven 脚手架的方式，创建和启动工程。这一节，我们先通过命令的方式使用。 + +## 四、应用场景举例 + +### 1. 普通对话 + +
+ +
+ +- 智能体搭建后，可以进行对话操作，基于你配置的 MCP 能力，它可以做很多事项。 + +### 2. draw.io + 画图 + +

星球：[https://t.zsxq.com/0d3o5FKvc](https://t.zsxq.com/0d3o5FKvc) - 课程入口 + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + + + +## 一、产品形态 + +这趟车🚌，本身的核心是关于**微服务应用体系的构建**，通过讲解配置`Docker`、`Nginx`、`SSL`等环境以及开发出`鉴权`、`认证`、`微信公众号`、`企业微信`、`支付宝交易`等模块的方式，完善体系的物料服务。而 ChatGPT 只是其中的一种产品形态而已，这种产品形态通过 API 的方式与具体的物料服务模块解耦。这样做的方式是因为基础的物料`【物料指SDK和服务】`并不会频繁变化，而离业务最近的 API 会随业务变动发生较多的改动。所以这样的应用架构方式，在互联网大厂中也是非常常见和常用的。 + +这些东西的价值在于架构思维，而我也希望授人以渔，教会大家一些根本的东西，而不是永远的在CV+CRUD。有了这样的学习，学习的就不只是这样一个项目，而是可以把这个项目中所涉及的组件开发，都能进行任意物料模块与需要对接的服务进行关联打通使用。方便`写到简历`、`用到项目`、`实战锻炼`、`积累经验`。 + +## 二、项目架构 + +- **目标**：此项目以围绕类似 ChatGPT 生成式服务，构建微服务应用架构体系组件。包括；用户鉴权、公众号、多方支付、企业微信等对接方式，满足不同诉求的使用。并以模块化设计，积木式构建应用，让不同的场景诉求都可以配置化对接。 +- **功能**：更直白一些就是通过这套微服务体系，可以构建出；`网页版ChatGPT对接`、`用户鉴权校验接口`、`关注公众号解锁`、`支付付费购买`、`公众号自动回复`、`企业微信聊天对接`、`知识星球对接`等。 + +那么这套系统是以`视频`和`小册`的教程为导向，教会大家开发这些各个模块的技术组件和技术服务。同时这里的组件和服务，都是微服务实现，可以被替换成其他任何一个你所需的内容。比如不是对接 ChatGPT 而是你想对接一个其他的服务也是可以的。 + +**整个系统架构如下**： + +
+ +
+ +如图；以用户请求为入口，通过 `Nginx SSL 443` 校验转发到对应的服务，并做相关的鉴权和服务控制，并完成最终的 token 授权使用。整套微服务包括系统；`chatgpt-api-sdk`、`chatgpt-auth`、`chatgpt-wx`、`chatgpt-pay`、`chatgpt-zsxq`、`chatgpt-admin`、`chatgpt-web` 服务。 + +## 三、拓扑结构 + +接下来我们再以工程拓扑的视角看下这套需要开发的系统； + +
+ +
+ +如拓扑结构，系统从上到下以不同的产品形态，统一调用封装的服务API进行功能的流转。API系统中所处理的核心动作，会以各个物料模块进行实现。所以这里会拆分出标准的 ChatGPT-API 业务系统，之后再由各个模块系统支撑。到具体的模块中再进行详细的系统设计。 + +## 四、技术使用 + +此项目会使用到 `SpringBoot`、`MyBatis`、`MySQL`、`Redis` 等技术栈，但因本项目主要以小成本，轻量维护的实际使用为主，所以不会过多引入分布式技术栈。所以在设计实现上，主要以小而美、小而精，且能匹配到真实场景的使用为主。—— 分布式技术栈是为了更大规模的体量使用，但也会为此付出运维和应用服务器成本。所以一些中小厂的项目或者创业类型的项目，都会优先更轻量级技术栈使用，以此减少这部分成本。 + +除技术栈的使用外，涉及到开发工具包括；`IntelliJ IDEA`、`WebStorm`、`Docker`、`Protainter`、`Nginx`、`Git`、`Maven`、`Navicat`、`SSH工具`等，以满足开发代码中的使用。 + +关于此项目可能还会涉及少部分 Next.js、Typescript 等前端知识，方便做 Web UI 的开发。 + +## 五、课程计划 + +
+ +
+ +此课程会包括，基础设置、模块开发、API服务等几块内容，而基础设施主要为一些基本操作，小傅哥会把一些这样的内容都放到这块，方便很多新人伙伴学习使用。这里会分为3个大的步骤； + +1. 在基础设置的基本必备服务搭建后，会进入接口鉴权的简单开发，这个模块开发后，大家就可以简单的使用了小傅哥提供的 OpenAI 了接口了。—— 当然你如果自己有 OpenAI 接口，也可以直接使用。**像 [https://huggingface.co/](https://huggingface.co/) 也提供了一些可以免费使用的简单 Open-API** +2. 有了这部分内容的使用，后续会进入 API-SDK 的开发，以及网页的简单开发。通过这样的开发构成一套基本的模块服务。ChatGPT-WEB-UI -> API-SDK -> 鉴权 -> OpenAI 的使用。 +3. ChatGPT-WEB-UI 流程🏃🏻跑通后，就可以逐步扩展其他服务模块。让业务与场景结合，如关注公众号、公众号回复、企业微信机器人、交易支付购买授权Token。这个过程可以让 ChatGPT-WEB-UI 与各个模块结合使用。 + +## 六、如何开始 + +这套课程会以`视频`、`小册`、`代码`、`作业`的方式进行推进，视频主要以演示操作、讲解核心的方式进行，并在小册和对应的代码中细化细节展示。鉴于星球有些在校的编程新手，所以关于`工程的创建`、`代码的提交`、`镜像的打包`、`容器的部署`等这些基础操作，也都会在视频中进行演示，方便大家更容易的上车。 + +### 1. 开通权限 + +星球课程涉及的代码部分会通过 [gitcode.net](https://gitcode.net/KnowledgePlanet) 提供，你只需要申请一次就可以授权到星球所有课程的代码仓库。授权申请地址：[https://t.zsxq.com/0dS1kW2r9](https://t.zsxq.com/0dS1kW2r9) - 审核后即可访问星球的项目仓库了。 + +### 2. 加群交流 + +小傅哥为星球伙伴创建了专属的VIP技术交流群，你可以通过扫码添加小傅哥的微信，备注上`你的星球编号`。我会给你拉到专属的微信群。 + +

+ +**走到腰部以上有什么秘诀？** + +说白了，咱们这么多人的地方，哪个行业都挺卷的。不拿出点本事走到腰部以上，自然就是感受到寒冬、不好过。而我看过的大部分伙伴，在职场中只是完成业务开发，那么1年、2年、3年，真到要晋升、跳槽、述职、答辩的时候，会发现自己哪哪都讲不出东西。而这就是我的「法宝」，从一开始工作，就不只是完成业务诉求，还不断地创新和做各类的组件，在一次次锻炼中让自己具备承接任何事项的架构和开发能力。 + +就像我们工作中所需的`JSON序列化组件`、`监控组件`、`熔断组件`、`缓存扩展组件`、`ES-ORM组件`、`慢查询监控组件`、`IDEA Plugin创建`、`数据压缩组件`等等，一开始根本不是有专门的团队做的，而是有一个喜欢创新的人自己独立完成的，在扩展到各个部门使用。那晋升怎么会少的了这个人，又怎么会让他感受寒冬。 + +这样的技术类组件小傅哥已经做了很多，今天在给启动一个新的 **《动态线程池组件》**，美团到店2020年，就有一款这样的组件分享，今天小傅哥教你如何手把手开发。 + +>文末获得5个业务项目 + 5个组件项目，1个源码学习，4套基础教程，帮助大家提升编程能力。 + +## 一、能学到啥 + +工作这么多年我发现，那些有晋升的，加薪多的，没有一个是不造轮子的！一直写业务的，踏实写业务的，就只能排队等着安排了。是因为做一些组件轮子，解决的是所有人的共性问题，这个价值非常大。并且在组件项目中你能掌握很多知识，如； + +- SpringBoot Starter 的设计和实现手段，以一个什么入口方式加载和启动组件。 +- 线程池核心信息的获取，核心线程数、最大线程数、活跃线程数、队列类型、队列任务数、队列剩余可用任务数，通过这些信息的学习和开发，也会更多的了解线程池。 +- 设计 Redis 版本的注册中心，通过 SDK 上报方式到 Redis 注册中心，做统一的管理，让各个接入动态线程池的组件都能统一管理。 +- 掌握 Redis 的发布订阅能力，通过推送指定的主题，让对应的应用上的 sdk 监听和处置线程池。 +- 定时任务 Scheduling 在组件中的启动和使用。*组件项目与日常业务项目不同，不能全都是硬编码* +- 简单前端页面的设计和开发，管理动态线程池。以及开发测试工程验证线程池使用。 + +## 二、项目介绍 + +本次带着大家做的这款动态线程池组件项目，也是各个中大厂中都非常常见的组件能力。通过这样的学习，以中大厂的经验补充自身的技术积累，让自己的简历和职业生涯都有东西可讲。 + +我们知道，线程池（Thread Pool），是一种基于池化思想管理线程的工具，用于降低资源消耗、提高响应速度、提高线程的管理性。池化技术的引入，可以有效的减少线程频繁申请/销毁和调度所带来的额外开销。对于池化思想，我们还能看到；内存池、连接池、化粪池。 + +但在实际的工作中，线程池使用的场景非常多，但线程池的参数并不好一次就配置好，同时需要做监控处理，知道整个线程的消耗情况。根据IO密集型，CPU密集型不通过的任务差异，做压测验证调整。所以有一款动态线程池是非常重要的。 + +### 1. 查看线程池 + +

课程：[https://t.zsxq.com/Pfekb](https://t.zsxq.com/Pfekb) + +>沉淀、分享、成长，让自己和他人都能有所收获！😄 + +大家好，我是技术UP主小傅哥。 + +**你说气人不**，每每公司`晋升提报`和`加薪`的时候，总是那些手里有俏活的👬🏻兄弟。业务项目虽然是根基，但大家都做也就拉不开差距，而技术类组件、通用服务、功能平台，倒不是所有人都能搞的，这类结合业务场景的提取共性问题，凝练成通用解决方案的项目，可以开发一个就解决了全大部门的问题，所以做这类项目很亮眼！ + +
+ +
+ +**这类项目也有门槛！** + +看着好像做个技术组件也没啥，但实际真想做的时候，你会发现你不知道什么服务可以被抽取为通用组件，不具备这样的经验和眼界。同时即使知道做啥了，也不知道如何结合像 Spring、MyBatis 源码能力，开发出一个通用的组件来，能让其他业务项目引入使用。 + +有人讲这东西不就是重复造轮子吗？🤔 还真不是，重复造轮子，指的市面上有的，或者公司里有个基础平台组有的。但这类的轮子往往不是深度结合业务的，而是那种无业务属性的功能逻辑的轮子，比如；rpc、xxl-job、mq 等。但一个业务组，他所需要的是解决通用业务场景问题的轮子，但这类东西又不属于基础平台研发组，所以往往都是业务组自己来解决这类场景问题。 + +所以，让自己具备开发组件的能力，是非常非常重要的，这即是抽象业务也是驾驭源码的能力体现。 + +小傅哥已经为大家提供了非常多的通用组件项目，如；`扳手工程（DCC动态配置中心、设计模式、动态限流、任务调度）`、`BCP 透视业务监控`、`动态线程池`、`支付SDK组件`、`SpringBoot Starter （16个合集）`、`IntelliJ IDEA Plugin 插件开发能力（具备这个的，开发了不少AI类组件）`。 + +这次小傅哥给大家再加一个新的组件《本地任务消息组件》，该组件解决业务场景远程调用HTTP或推送MQ消息，最终一致的问题。 + +## 一、能学到啥 + +【架构】掌握 DDD 分层与端口-适配器模式，清晰划分 domain/infrastructure/trigger/config 模块，提升可维护性与扩展性。 +【后端】学习注解+AOP 方式受理任务消息，结合事务边界进行统一处理，理解 `@LocalTaskMessage` 与切面配合的落地实践。 +【后端】掌握本地消息表设计与分片扫描策略（按门牌号 houseNumber 分片），实现高效拉取与顺序处理，提升系统可靠性。 +【后端】熟悉 Spring Event 事件驱动与异步消费，使用 `ApplicationEvent`+`@EventListener`+`@Async` 实现解耦通知链路。 +【后端】实践策略模式实现可插拔通知能力，支持 HTTP 与 RabbitMQ 两种通知通道，并在成功/失败时更新任务状态。 +【后端】熟练使用 OkHttp3 与 Retrofit2 统一封装 HTTP 网关，掌握动态 URL、Header、Body 的组合与异常处理。 +【后端】了解 RabbitMQ 事件发布的可选依赖注入方式，避免未配置 MQ 时的强依赖导致应用启动失败。 +【配置】掌握 `@ConfigurationProperties` 驱动的多任务组动态调度配置，支持 cron 与 fixedDelay 两种触发方式，并可配置批次大小 limit。 +【运维】学习 `ThreadPoolTaskScheduler` 的线程池化调度管理，合理设置线程名与池大小，提升任务调度的可观测性与稳定性。 +【数据】掌握原生 JDBC 访问与 DAO 封装，完成插入、状态更新、分片条件查询、最小游标查询等落地实现。 +【测试】通过示例命令对象 `TaskMessageEntityCommand` 的构建与调用，理解入参约定、枚举策略与配置对象的协作。 +【实践】提升异常、日志与枚举的综合使用能力，建立稳定的错误处理。 + +## 二、项目介绍 + +**《本地消息任务组件》** 项目，是以自定义注解 AOP 切入或编程的方式，动态化完成数据库表事务和消息推送（HTTP、MQ），达到最终一致性的目的。 + +>在没有这样的组件的时候，为了完成业务流程的同时，在发送一个MQ消息或则远程调用 HTTP 操作，都需要自己写一个本地消息表，之后还要维护消息表的扫描补偿。 + +操作方式如图； + +
+ +
+ +- 用户可以选择通过注解或者直接调用组件服务的方式进行使用。也就不用业务项目工程再维护关于本地消息表的写入和 MQ 或者 HTTP 的处理和补偿了。 +- 注解方式，会自动获取入参，入参需要为 TaskMessageEntityCommand 对象，它可以是某个入参的对象。之后配置 req.command 也可以获取。 + +## 三、产品方案 + +### 1. 产品概述 + +本地任务消息组件基于 Spring 框架能力，设计并实现了通用功能内核，便于集成到各类业务系统中。在业务系统中，组件支持在事务内完成数据写库的同时，写入一条本地消息记录（需在业务系统数据库中创建符合组件规范的本地消息表）。写入完成后，组件同步推送 Spring 事件，触发事务外的异步处理，如 MQ 消息发送或 HTTP 回调。即使异步处理失败，组件内置的本地消息表定时任务（支持自定义配置“门牌号”多任务并行扫描，提升扫描吞吐量）会持续检测并重试通知，确保消息最终一致性和业务流程的可靠执行。 + +### 2. 技术架构 + +
+ +
+ +- 首先，Local Task Message 任务消息组件，是以解决通用业务场景中的，本地数据库事务和外部MQ/HTTP调用一致性问题而设计实现的。让上游业务系统，不需要在每个流程中，都要做大量的重复编码。而是通过注解或者直接调用组件内核服务即可完成消息的通知操作。 +- 之后，Local Task Message 任务消息组件，并不是一个单纯的工具性功能，而是剩余一个领域服务内核，它具备完整的领域功能，具备操作数据库表的能力，以及接收 Spring Event 事件，对接 MQ、HTTP 完成和外部的交互处理。 +- 然后，上游系统在使用这套服务时，只需要配置好对应的本地消息表（一个事务下，连的同一个库），以及引入组件和完成yml配置，即可直接使用。 + +### 3. 功能流程 + +
+ +
+ +- 引入本地消息组件后，以用户开发dao入库操作为开始，可以通过注解或者调用组件服务 `ILocalTaskMessageHandleService` 驱动同一个事务下，进行消息推送。 +- 切面的方式，会更为优雅简洁，不需要用户自己在维护调用关系。 +- 整个操作会由组件自行处理写库操作，基于 Spring Event 的监听和通知，触发消息推送。完成 http、mq 的调用逻辑。同时还有基于门牌号扫描的逻辑，增强吞吐量。 + +## 四、课程目录 + +现课程已全部录制完成，接下来会日更📅项目💐； + +
+ +
+ +- 6节课程，全程视频手把手，带着你分析需求，编写代码。快速完成一个组件项目。 +- 课程代码，以互联网公司方式逐步拉分支开发，你可以学习到正规的编码操作。 diff --git a/docs/md/zsxq/project/lottery.md b/docs/md/zsxq/project/lottery.md index f71fc1b3d..8b3e9770d 100644 --- a/docs/md/zsxq/project/lottery.md +++ b/docs/md/zsxq/project/lottery.md @@ -7,7 +7,7 @@ lock: no 作者：小傅哥

+ +--- + +说到底，为什么要扒开CRUD的表面，深入到核心源码实践学一些中间件开发技能，还不是希望自己对技术栈学习有一定的深度，免得面试时被人忽悠压薪资。就像人家问你： +- 类的代理、反射调用是在什么场景用到的？ +- 自定义注解是怎么和切面一起获取到信息使用的？ +- 你需要的yml配置信息是如何被SpringBoot加载并初始化的？ +- Bean 是如何被注入到 Spring 容器，提供服务的？ +- ORM 框架是怎么解决不需要写接口的实现类就能执行CRUD操作的？ +- 扰动函数和数据库路由实现中的数据散列有什么关系？ +- 分布式任务调度与zookeeper配置中心是怎么联动的？ +- 字节码插桩对方法增强怎么拦截程序方法运行时信息？ + +**综上**，等等这些技术点可能很多时候你所学到的只能称作为`背答案`、`记结果`，因为没有实操所以过后就忘而且也扛不住面试官的接连发问。 + +**那么**，为了让所有对需要对自己技术栈知识加深，拓展相关技能的实战经验，同时也让感兴趣于薪资高的中间件开发的小伙伴，有一个能入门并上手的教程。特此准备了专栏小册`《SpringBoot 中间件设计和开发》`，欢迎大家加入！ + +**全小册19个章节，包括16个中间件的设计和开发，包括测试案例共30个代码库提供给读者学习使用。小册实现的中间件场景涵盖：技术框架、数据服务、数据组件、分布式技术、服务治理、字节码、IDEA插件七个方面，贯穿整个互联网系统架构中常用的核心内容。非常值得了解、学习、实践到掌握。** + +💋`鉴于作者水平有限`，如果书中含有不易理解的内容，一定是作者在编写的过程中缺少必要的描述和严格的校准，感谢把你的意见或者疑问提交给我，也欢迎与我多一些交互，互相进步共同成长。 + +## 二、中间件开发技术 + +如果平常只是更多的做一些业务代码的开发，那么接触的技术一般是在各类组件的 API 使用上，以及对不同接口的包装。而中间件开发会涉及到各类框架的源码和原理，以及相应的技术迁移和复用。那么在我们这次中间件的设计和实现中，会学到框架、数据、治理、分布式以及字节码的相关技术栈知识，整体包括如下： + +![图 2-1](https://bugstack.cn/assets/images/middleware/2-1.png) + +- **技术框架**：包括 Spring、SpringBoot 配置加载、自定义注解、扫描注册Bean等，以及 ORM 框架设计原理和实现。这部分技术主要是把开发的中间件与框架结合，开发相应的组件或者包装为各类 SpringBoot Starter 的能力学习。 +- **数据服务**：Mysql、Redis、Elasticsearch，都是数据服务，通常需要开发各类组件对数据服务的使用进行封装，Mysql 我们知道有 JDBC，Redis 我们知道有 Jedis，但 Elasticsearch 有 x-pack 你是否了解。 +- **数据组件**：这类组件的开发就是为了简化对数据服务的使用，Mysql+JDBC+ORM，可以非常方便的使用数据库服务，那么 Elasticsearch 是否也可以做相应的组件研发，让它的查询也能像使用 MyBatis 一样呢？二折页的技术能力就需要对 MyBatis 等 ORM 框架的实现原理熟悉，同时需要了解 JDBC 的概念。 +- **分布式技术**：RPC 框架、注册中心、分布式任务，都是现有互联网分布式架构中非常重要的技术，而对于如何实现一个 RPC 框架，也技术是研发人员要掌握的重点，同时如何使用注册中心、怎么下发分布式调度任务，等等，这些技术的学习能让对现有的框架使用有更深入的认识。 +- **服务治理**：熔断、降级、限流、切量、黑白名单以及对现有方法的非入侵式扩展增强等，都可以成为是服务治理类组件，原本这类技术在早期是与业务逻辑代码融合的，后来逐步被拆解出来，开发成对应的组件。所以我们可以学习到，关于这类组件的包装、集成是如何做的。 +- **字节码&插件**：在互联网的系统应用运维过程中，你一定会接触到各类的监控系统，而很多监控系统是非入侵的全链路监控，那么这些是如何实现的呢？其实它们是基于字节码插桩，对系统方法的增强，采集相应的运行时信息，进行监控的。再到扩展 JVMTI、IDEA 插件开发，都是为了整个研发过程的可持续交付和上线提高交付质量和降低人效的。 + +**综上**，这些贯穿整个互联网系统架构中的各类典型中间件，都会在后续章节中陆续讲解出来，它们是如何设计和实现的，一点点带你解开中间件的神秘面纱，让你的技术栈知识也增加一些有深度的并且是可以亲自操作的内容。 + +## 三、中间件设计和实现列表 + +| 序号 | 图标 | 名称 | 描述 | +| :--: | :--: | ---- | ---- | +| 1 |

+ +
+ +**这是一个什么项目？** + +在互联网公司真实业务开发场景下，往往会有很多的业务工程系统进行落地，如；电商、交易、信贷、营销、分润、清分/结算等等，这些业务场景会落地非常多的业务系统。而这些业务系统中，会有很多的相同的非业务逻辑的共性技术诉求的处理，如；动态属性配置、熔断、限流、异常、数据采集监控、增强的mock服务、流量录制回放、切面拦截日志、模型设计框架等等。 + +这些共性的组件东西，不可能让每个系统全部自己实现一遍，既耗费人力，最后又实现的五花八门非常难维护。所以，在互联网公司中，会单独把这类通用的逻辑凝练成共用的技术组件，让所需的业务场景进行引入使用。 + +
+ +
+ +那么，这就是小傅哥要带着你做的一款通用《扳手工程》 SpringBoot Starter 系列组件，用于星球的业务项目中使用。**😂 星球里也确实有非常多的业务项目了，不开一个这样东西，那么就要很多业务项目都重复的实现！** + +> 💐 文末提供了17套实战项目源码，8套业务（含最新 AI RAG MCP）、8套组件，还有1套源码教程。 + +## 一、能学到啥 + +该项目是以真实的互联网企业架构方案为指导，建设星球业务项目通用技术组件支撑平台。全程手把手分析需求、架构工程、从0到1编码，让大家可以深入理解和学习组件化设计和落地。 + +- 深入学习 Spring、SpringBoot、MyBatis 框架源码，掌握 SPI 机制实例化组件入口，理解 Spring Bean 生命周期与 BeanPostProcessor 的实际应用，实现属性级别的动态注入与代理。 +- 掌握 Redisson 客户端的配置与使用，基于 Redis 实现分布式发布/订阅消息机制。 +- 理解自定义注解实现配置属性的自动注入与动态刷新，学习分布式系统中配置中心的设计与实现，提升组件化开发与扩展能力。 +- 深入学习 Spring AOP 切面编程，掌握注解驱动的方法拦截与增强技术。 +- 熟练运用 Guava RateLimiter 实现令牌桶算法的接口限流保护机制。 +- 掌握自定义注解与反射机制结合，实现灵活的功能配置与参数提取，精通本地缓存设计与管理，提升系统性能与资源利用率。 +- 深入理解分布式系统限流与降级策略，构建高可用服务保障体系。 +- 熟练应用代理模式与策略模式，提升代码的可扩展性与可维护性，掌握 Java 反射机制在属性获取与方法调用中的高级应用。 +- 精通动态配置管理与功能开关设计，实现系统的灵活控制，深入理解异常处理与日志记录的最佳实践，提升系统可观测性。 +- 掌握面向接口编程思想，设计支持分布式场景扩展的组件架构，深入掌握责任链模式在复杂业务流程中的应用，提升系统解耦与扩展能力。 +- 学习策略模式在动态业务路由与决策中的实现，增强系统灵活性，掌握泛型与函数式接口在设计模式中的高阶用法，提升代码复用性与类型安全。 +- 理解链式调用与链路装配技术，实现业务处理链的灵活组装与动态扩展，掌握多线程与异步策略路由的设计与实现，提升系统并发处理能力。 +- 学习接口+抽象类+实现类的分层设计思想，为后续 SPI 等机制扩展预留入口。 + +以上，仅是关于组件技术开发的一部分，如果你想把一些之前硬背过的关于核心技术组件场景解决方案的东西彻底学会，而不是简简单单的背，那么这趟技术列车千万别错过。 + +## 二、项目介绍 + +本次项目你会学习到非常多的共性场景解决方案，这些内容可以引入到你做过的业务项目中进行使用。全过程以实际问题场景触发，设计解决方案，手把手编码。组件项目完成后，还会带着你发布自己的Jar到共有平台（https://mvnrepository.com/） 其他人也能引入使用。 + +### 1. 背景举例 + +
+ +
+ +当你学习大营销、拼团、OpenAI 应用等业务系统时，会遇到很多同类的功能诉求，如；规则树的设计模式、DCC 动态配置中心、接口限流配置等。这些东西其实都可以被抽象凝练成一个通用的技术组件，引入后直接配置使用即可，而不需要在每个业务系统中都开发一遍。 + +### 2. 架构设计 + +设计通用的统一规范的扳手工程； + +
+ +
+ +- 首先，我们会搭建一套标准的扳手框架 Spring Starter 工程。在工程内，以模块化方式陆续实现，动态配置、限流服务、通用设计模块框架。 +- 之后，以 Redis 作为简单注册中心使用，管理动态配置、限流服务等，再以 admin 管理端，下达配置命令，来动态操作工程配置。 + +### 3. 工程模型 + +
+ +
+ +- 定义 xfg-wrench 扳手工程，以 xfg-wrench-starter 为前缀，命名各项服务组件。如；`xfg-wrench-starter-dynamic-config-center` +- xfg-wrench-test 为测试工程，用于验证各个模块的功能实现。 +- xfg-wrench-admin 为管理后台，后续陆续创建完成。以及其他模块组件陆续迭代开发。 + +### 4. 流程设计（举例 DCC 动态配置） + +如图，动态配置中心功能流程设计； + +
+ +
+ +- 以 SPI 机制，实现组件入口类的注册。驱动注册中心和 Spring 容器工作。也就是工程的 `META-INF/spring.factories` 文件里配置的类，会被引入此组件的其他 SpringBoot 应用进行调用启动。 +- 接下来，注册配置会链接 Redis 当做注册中心使用。因为 Redis 具备了存储和发布订阅的功能，如 Dubbo 也可以使用 Redis 作为简单注册中心使用一样。而后出初始化动态配置中心的服务，以及监听订阅消息。 +- 在之后，拦截 Spring 容器实例化的 Bean 对象，找到使用了自定义注解 `@DCCValue` 的属性，对其拦截动态读取 Redis 中配置属性值（如无则首次设置值），之后对属性进行反射调用，设置变更后端 属性值。 +- 最后是，我们操作推送 Redis 发布订阅消息，则可以被消息回调，变更属性值。 + +## 三、加入学习 + +课程采用 `文档` + `视频`教程，全流程带着你分析和实现，并且会把组件也业务项目结合。小傅哥带着你做的，就是互联网中真实场景的运用。 + +
+ +
+**注意📢**，本项目也只是**【星球：码农会锁】**众多项目中的1个，其他的项目还包括：拼团、大营销、小型支付商城、AI RAG MCP、OpenAI 代码自动评审、动态线程池、支付SDK、API网关、Lottery抽奖、IM通信、SpringBoot Starter 组件开发、IDEA Plugin 插件开发等，并还有开源项目学习。 + +> 这将是一个新的技术旅程，在这趟车上🚗，你会了解到互联网公司大厂🏭是如何对这类场景的方案落地的。 diff --git a/otter.md b/otter.md new file mode 100644 index 000000000..a2e91fe39 --- /dev/null +++ b/otter.md @@ -0,0 +1,15 @@ +**💐🧧活动：** - 完成后私聊我（备注星球编号）获取奖励。 + +1. 所有今天加入的伙伴，都赠送 `100万 Token 4.0` 助力编程学习。 +2. 推荐其他伙伴加入，私聊发送加入者星球编号给我，你可以获得 `100万 Token 4.0` + +
