</project>

6 创建gamll-user-web模块--SpringBoot项目

存放Controller文件：需要依赖父工程，引入gmall-api和gmall-web-util

项目结构：

说明：

Controller需要引入Reference，调用注册的服务，UserService接口定义在gamll-api模块中；UserServiceImpl类定义在gmall-user-sevicce中

import com.alibaba.dubbo.config.annotation.Reference;

application.properties:

# 服务端口
server.port=8080

# 日志级别
logging.level.root=info

# dubbo的配置
# dubbo中的服务名称
spring.dubbo.application=user-web
# dubbo的通讯协议名称
spring.dubbo.protocol.name=dubbo
# zookeeper注册中心的地址
spring.dubbo.registry.address=10.14.237.221:2181
# zookeeper的通讯协议的名称
spring.dubbo.registry.protocol=zookeeper
# dubbo的服务的扫描路径
spring.dubbo.base-package=com.atguigu.gmall
# 设置超时时间
spring.dubbo.consumer.timeout=600000
# 设置是否检查服务存在
spring.dubbo.consumer.check=false

pom文件：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

7 创建gamll-user-service模块--SpringBoot项目

存放service和mapper文件：需要依赖父工程，引入gmall-api和gmall-service-util

项目结构：

说明：

此模块主要负责service层和mapper操作数据库；操作数据库主要是由的是通用mapper

（1）在启动类中定义MapperScan：这里使用的是通用mapper的MapperScan

（2）serrvice类引入的@Service注解是dubbo的

（3）引入UserMapper使用的是@Autowired，且UserMapper需要继承通用Mapper

application.properties：

# 服务端口
server.port=8070

# jdbc
spring.datasource.password=123456
spring.datasource.username=root
spring.datasource.url=jdbc:mysql://localhost:3306/gmall?characterEncoding=UTF-8

# mybtais配置
mybatis.mapper-locations=classpath:mapper/*Mapper.xml
mybatis.configuration.map-underscore-to-camel-case=true

# 日志级别
logging.level.root=debug

# dubbo的配置
# dubbo中的服务名称
spring.dubbo.application=user-service
# dubbo的通讯协议名称
spring.dubbo.protocol.name=dubbo
# zookeeper注册中心的地址
spring.dubbo.registry.address=10.14.237.221:2181
# zookeeper的通讯协议的名称
spring.dubbo.registry.protocol=zookeeper
# dubbo的服务的扫描路径
spring.dubbo.base-package=com.atguigu.gmall

pom文件：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

	<parent>

二、项目测试：

1 在gmall-api中加入javabean

注意:一定要序列化，实现Serializable接口

public class UmsMember implements Serializable{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String id;
    private String memberLevelId;
    private String username;
    private String password;
    private String nickname;
    private String phone;
    private int status;
    private Date createTime;
    private String icon;
    private int gender;
    private Date birthday;
    private String city;
    private String job;
    private String personalizedSignature;
    private int sourceType;
    private int integration;
    private int growth;
    private int luckeyCount;
    private int historyIntegration;
}

2、在gmall-user-web中定义UserController

package com.atguigu.gmall.user.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.atguigu.gmall.bean.UmsMember;
import com.atguigu.gmall.service.UserService;
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 UserController {

    @Reference
    UserService userService;

    @RequestMapping("/getAllUser")
    @ResponseBody
    public List<UmsMember> getAllUser(){

        List<UmsMember> umsMembers = userService.getAllUser();

        return umsMembers;
    }

}

3、在gmall-user-api中定义UserService接口

package com.atguigu.gmall.service;

import com.atguigu.gmall.bean.UmsMember;

import java.util.List;

public interface UserService {

    List<UmsMember> getAllUser();
}

4、在gmall-user-service中定义UserServiceImpl实现类和UserMapper

UserServiceImpl :

package com.atguigu.gmall.user.service.impl;

import com.atguigu.gmall.bean.UmsMember;
import com.atguigu.gmall.service.UserService;
import com.atguigu.gmall.user.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import tk.mybatis.mapper.entity.Example;
import com.alibaba.dubbo.config.annotation.Service;

import java.util.List;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;

    @Override
    public List<UmsMember> getAllUser() {

        List<UmsMember> umsMembers = userMapper.selectAll();//userMapper.selectAllUser();

        return umsMembers;
    }

}

UserMapper :

package com.atguigu.gmall.user.mapper;

import com.atguigu.gmall.bean.UmsMember;
import tk.mybatis.mapper.common.Mapper;

import java.util.List;

public interface UserMapper extends Mapper<UmsMember>{

    List<UmsMember> selectAllUser();

}

5、运行gamll-user-service和gmall-user-web

访问：http://localhost:8080/getAllUser  即可获取用户用户信息
