[](()3. 编写数据源的相关配置

application.properties

server.port=8082

数据库配置

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/springboot?useUnicode=true&characterEncoding=UTF-8

spring.datasource.username=root

spring.datasource.password=root

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

mybatis.mapper-locations=classpath:/mapper/*Dao.xml

[](()4. 在 dao 接口添加 @Mapper 注解

@Mapper

public interface UserDao {

......

}

[](()三、测试

controller 层

（不再展示其它层代码，展示 controller 是为了方便查看请求路径）

package com.parker.controller;

import com.parker.entity.User;

import com.parker.service.UserService;

import org.springframework.web.bind.annotation.*;

import javax.annotation.Resource;

/**

• (User)表控制层

• @author 扬帆向海

• @since 2020-05-15 00:56:29

*/

@RestController

@RequestMapping("user")
