微服务项目实战练习

Build Status codecov

说明:

  1. 如果您之前从未接触过Spring Cloud,建议先以程序猿DD-Dalston版 开始学习,或者您可以浏览我的学习DemoSpringCloud-Learing
  2. 如果您想学习nacos在项目中应用,阿里出厂的nacos:一个更易于构建云原生应用的动态服务发现、配置管理和服务管理平台;用Spring Cloud组件理解的话,约等于eureka+spring cloud config
  3. 如果您想学习seata在项目中应用,阿里出厂的seata:一款开源的分布式事务解决方案,致力于在微服务架构下提供高性能和简单易用的分布式事务服务
  4. 以上项目组件您都有接触,但是想练习这些组件如何在项目中有机结合使用,那您真是来对地方了

因作者技术水平有限,如您发现可能存在的问题,欢迎指正,以便相互学习!

介绍

  1. microservice-mobile:移动端接口服务(可做app/小程序/网页端服务)
  2. microservice-web:web管理端接口服务
  3. microservice-scheduled:处理定时任务
  4. microservice-tool:项目基础依赖工具
  5. microservice-repository:项目基础数据依赖

框架结构

  1. web端使用shiro做用户权限管理

  2. 使用Nacos实现服务注册与发现

  3. 使用Nacos作为配置中心

  4. 使用gateway做服务网关

  5. 使用feign做服务之间api调用

  6. 使用hystrix做服务容错处理

  7. 使用gateway网关对服务内swagger统一管理,从http://localhost:8888/swagger-ui.html

  8. 使用zipkin实现分布式跟踪系统,需要下载zipkin.jar => https://github.com/openzipkin/zipkin

  9. 使用seata实现分布式事务:https://seata.io/zh-cn/docs/user/configurations.html

    调用实现:

    microservice-mobile---DistributedTransactionController->saveTest()

    --服务调用-->

    microservice-web---DistributedTransactionController->saveTest()

软件结构

├─controller //提供外部接口
├─dao 
│  └─queryFactory //自定义查询
│  └─repository //jpa查询
├─pojo
│  ├─bo //业务对象
│  └─vo 
│      ├─req //前端请求对象
│      └─resp //前端返回对象
├─process
│  └─impl //接口的实现过程
└─service //具体过程的业务功能实现

安装教程

说明:在开始使用之前建议您已了解并熟悉上述框架结构中所涉及到的技术模块

  1. 安装并启动nacos,官网安装配置教程:Nacos Spring Cloud快速开始
  2. 安装并启动seata,官网安装配置教程:Seata新手部署指南 不装也可以,只不过会一直打印日志,注册不上seata
  3. install microservice-tool
  4. install microservice-repository
  5. start microservice-mobile/microservice-scheduled/microservice-web

功能事项

缩包部署

  • microservice-mobile、microservice-scheduled、microservice-web都已使用maven插件打包时将依赖jar包单独复制到lib目录, lib包可以单独放在服务器的和项目的相对路径,以后部署时就用上传jar包,减少部署项目上传的时间。

microservice-gateway

开放性
  1. 项目所有接口不对外开放,请求走microservice-gateway进行访问;
  2. 项目使用swagger做接口文档,可用于接口测试;microservice-gateway集成统一调用microservice-mobile和microservice-web的swagger-ui; 启动后可请求http://localhost:8888/swagger-ui.html进行访问;
权限认证/参数校验/日志打印
  1. 由GlobalRequestFilter#logTrace负责接口的访问权限认证和参数校验;
  2. IgnoreUri忽略路径,忽略访问权限和返回参数包装的uri;可在nacos中进行配置;
响应体包装
  1. 由ModifyResponseBodyFilter调用ResponseBodyAdvice对返回body进行包装;

microservice-mobile

  1. 从microservice-gateway进来的请求标记URIPrefixEnum#EXTERNAL为外部请求;
  2. 从microservice-mobile到microservice-web的请求,即内部请求,非来自microservice-gateway的请求会在feign中标记URIPrefixEnum#INTERIOR为内部请求;内部服务调用不包装返回体;//后续可做拦截处理等

microservice-web

说明:系统用户首先登陆,登陆后可以调用接口获取自己的权限菜单

访问日志
  1. 对敏感权限使用LogHandlerInterceptor#postHandle记录操作日志,存储在sys_log表中;
权限管理
  1. 使用shiro做权限管理;

注意事项

  1. 新增接口时保持接口路径与sys_permission表所存储url路径基本一致,如接口路径approve/config/titleList,url存储为configTitleList
  2. 接口功能为新增/修改/删除/锁定时,sys_permission表中权限名称则以该关键字符开头
