代码请前往我上传的资料 分布式电商系统
zk使用window版本
商城
一、主要功能点:
- 前后分离
- FastDFS图片上传. springboot配置静态资源上传路径
- 商品展示
- 全文搜索
- 购物车
- 订单
- 支付
- 单点登录（一个公司下有多个项目，某个场景中A项目中用到B项目，A项目不用等了都可以使用B项目相关服务）、第三方登录
- 支付订单和库存消息通知【分布式事物】
- 秒杀、限流
- 运维部署 docker + k8s
建立模块的时候，使用maven工程，使用parent标签引用父工程。
项目框架搭建
每个模块需要的依赖
分布式微服务
二、项目架构
- gmall —– 项目文件夹
- gmall-parent 版本控制
- gmall-common-util
- gmall-service-util —— 通用服务工具类
- gmall-web-util
- gmall-api ——接口
- gmall-user-service
- gmall-user-web ——这个是给前端工程访问 @restController

编写接口和存放相关的bean。也可以把bean放到common-util 这个要看个人怎么搭建项目架构.user-web。依赖api接口，不就把bean一起了。

public interface UmsMemberMapper extends BaseMapper<UmsMember> {

}
通用mapper和springboot整合，还有如果需要写xml文件的sql。需要在application.properties中指定xxxMapper.xml文件的路径,需要tik.mapper和springboot整合jar包,需要mybatis的jar包。

6.5 UmsMemberServiceImpl.java
注意:@Service 使用dubbo
package com.atguigu.gmall.user.service.imp;

import com.atguigu.gmall.bean.UmsMember;
import com.atguigu.gmall.service.UmsMemberService;

@Autowired
private UmsMemberMapper umsMemberMapper;
@Override
public List<UmsMember> findUmsMemberAll() {
return umsMemberMapper.selectAll();
}
}
6.6 启动类
注意:@MapperScan使用tk.mapper的
package com.atguigu.gmall.user;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import tk.mybatis.spring.annotation.MapperScan;
@SpringBootApplication
@MapperScan(basePackages = "com.atguigu.gmall.user.mapper")
