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

5.gmall-api

5.1 pom.xml

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。

6.2 UmsMemberMapper.java

package com.atguigu.gmall.user.mapper;
import com.atguigu.gmall.bean.UmsMember;
import tk.mybatis.mapper.common.BaseMapper;
import java.util.List;
public interface UmsMemberMapper  extends BaseMapper<UmsMember> {

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。

6.3 application.properties

# 服务端口

# dubbo的服务的扫描路径

6.4 UmsMemberMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.atguigu.gmall.user.mapper.UmsMemberMapper">
<select id="selectAllUser" resultType="com.atguigu.gmall.bean.UmsMember">
select t.*  from ums_member t
</select>
</mapper>

6.5 UmsMemberServiceImpl.java

注意:@Service 使用dubbo

package com.atguigu.gmall.user.service.imp;
import com.alibaba.dubbo.config.annotation.Service;
import com.atguigu.gmall.bean.UmsMember;
import com.atguigu.gmall.service.UmsMemberService;
import com.atguigu.gmall.user.mapper.UmsMemberMapper;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.List;
@Service
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);
}
