电商平台解决方案

项目简介

这一一个基于SpringCloud Alibaba框架开发的一个电商工程,主要目的是从真实业务场景出发,落地微服务组件的集成和应用工程编码、部署、测试流程与规范。工程主要分为商品服务、地址服务、用户账户服务以及物流服务模块。

技术栈

  • 后端:SpringBoot + SpringCloud + JPA
  • 数据库:MySQL + Redis
  • 消息中间件:Kafka
  • 工具:Sentinel + Zipkin + Seata

工程结构

项目总共拥有10个子模块,分别为e-commerce-admin、e-commerce-alibaba-nacos-client、e-commerce-authority-center、e-commerce-common、e-commerce-gateway、e-commerce-hystrix-dashboard、e-commerce-mvc-config、e-commerce-sentinel-client、e-commerce-service、e-commerce-stream-client,其中各模块主要功能如下:

  • e-commerce-mvc-config:提供了全局统一响应处理机制以及统一拦截器,并提供了忽略响应处理的注解
  • e-commerce-common:提供公共的 vo 如用户信息、token信息等等,还提供了 Jwt 解析工具
  • e-commerce-alibaba-nacos-client:用于提供工程验证,不属于线上的功能模块。在该模块中主要验证了 Nacos、Hystrix、Sleuth、Feign及Ribbon等组件
  • e-commerce-admin:集成了 Spring Security 框架,对所有请求进行安全认证;提供了报警机制,实例状态改变会进行通知
  • e-commerce-authority-center:主要提供授权功能,即 token 的生成
  • e-commerce-gateway:网关模块,提供了动态路由更新机制(即Nacos中修改了路由配置,本地会打印相关日志信息),提供了全局过滤器完成鉴权、计时等工作
  • e-commerce-service:业务模块,主要包含 用户账户、商品、订单、物流 四个子模块
  • e-commerce-hystrix-dashboard:hystrix控制台模块
  • e-commerce-stream-client:消息通信模块
  • e-commerce-sentinel-client:限流控制台模块

技术亮点

  1. 采用领域驱动设计(DDD)的思想进行建模,提高系统的可扩展性
  2. 利用 Jwt 机制完成授权鉴权,即服务器收到用户请求后与数据库中的用户信息对比,若对比成功,则利用私钥加密用户信息并生成 Jwt,Jwt 的优势在于存储在 Header 中,可扩展性强,相比较下,session需要做多机数据共享。
  3. 实现了拦截器,并在拦截器内利用 ThreadLocal 单独存储每一个线程的用户信息
  4. 实现了商品异步入库,步骤如下:
    • 自定义线程池
    • 实现异步入库接口
    • 定义异步监控切面,设置异步任务执行状态
  5. 利用 Seata 实现分布式事务管理,主要用于订单创建功能,因为在订单创建过程中存在商品扣减,用户账户余额扣减以及物流消息传递
