01_分布式电商系统搭建dubbo+zk+SpringBoot

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

    List<UmsMember> selectAllUser();
}

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。

public class UmsMemberServiceImpl  implements 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")
public class GmallUserServiceApp {
   

    public static void main(String[] args) {
   
        SpringApplication.run(GmallUserServiceApp.class, args);
    }

}

7.2 UmsMemberController

注意:@Reference 使用dubbo 相当于 @Autowried

package com.atguigu.gmall.user.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.atguigu.gmall.bean.UmsMember;
import com.atguigu.gmall.service.UmsMemberService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

@Controller
public class UmsMemberController {
   

    @Reference
    private UmsMemberService umsMemberService;

    @RequestMapping("/findAll")
    @ResponseBody
    public List<UmsMember> findAll(){
   
        return umsMemberService.findUmsMemberAll();
    }
}

7.3 启动类

package com.atguigu.gmall;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class GmalUserWebApplication {
   
    public static void main(String[] args) {
   
        SpringApplication.run(GmalUserWebApplication.class,args);
    }
