一、数据库新建用户（user）表

二、利用mybatis-generator生成代码

可参考[【记录·后端篇-2】springboot集成mybatis-generator\_郝南过的博客-CSDN博客][-2_springboot_mybatis-generator_-CSDN]

（1）在生成的UserMapper接口上添加注解**@Repository**

（2）创建UserController、UserServer以及UserviceIpml（实现自带的selectByPrimaryKey为例）

**UserController.java**（注意添加注解）

> package com.hng.example.controller;
> 
>     import com.hng.example.entity.User;
>     import com.hng.example.service.UserService;
>     import org.springframework.beans.factory.annotation.Autowired;
>     import org.springframework.web.bind.annotation.RequestMapping;
>     import org.springframework.web.bind.annotation.RestController;
>     
>     /**
>      * @Author 郝南过
>      * @Date 2022/11/6 19:04
>      * @Version 1.0
>      */
>     @RestController
>     public class UserController {
>     
>         @Autowired
>         private UserService userService;
>     
>         @RequestMapping("/hello")
>         public User hello(){
>             return userService.selectByPrimaryKey(1);
>         }
>     }

**UserServer.java**

>     package com.hng.example.service;
>     
>     import com.hng.example.entity.User;
>     
>     /**
>      * @Author 郝南过
>      * @Date 2022/11/4 11:14
>      * @Version 1.0
>      */
>     public interface UserService {
>     
>         User selectByPrimaryKey(Integer id);
>     }

UserServiceImpl.java (注意添加注解**@Service**)

>     package com.hng.example.service.impl;
>     
>     import com.hng.example.entity.User;
>     import com.hng.example.repository.UserMapper;
>     import com.hng.example.service.UserService;
>     import org.springframework.beans.factory.annotation.Autowired;
>     import org.springframework.stereotype.Service;
>     
>     /**
>      * @Author 郝南过
>      * @Date 2022/11/6 19:07
>      * @Version 1.0
>      */
>     @Service
>     public class UserServiceImpl implements UserService {
>     
>         @Autowired
>         private UserMapper userMapper;
>     
>         public User selectByPrimaryKey(Integer id) {
>             return userMapper.selectByPrimaryKey(id);
>         }
>     }

三、启动类上方添加mapper扫描 **@MapperScan("com.hng.example.repository")**

>     package com.hng.example;
>     
>     import org.mybatis.spring.annotation.MapperScan;
>     import org.springframework.boot.SpringApplication;
>     import org.springframework.boot.autoconfigure.SpringBootApplication;
>     
>     @SpringBootApplication
>     @MapperScan("com.hng.example.repository")
>     public class ExampleApplication {
>     
>         public static void main(String[] args) {
>             SpringApplication.run(ExampleApplication.class, args);
>         }
>     
>     }

四、application.properties中添加**\*\*mapper.xml**扫描位置

>     # db
>     spring.datasource.url=jdbc:mysql://xxx.xxx.xxx.xxx:3306/hng
>     spring.datasource.username=root
>     spring.datasource.password=password
>     spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
>     
>     # mybatis-generator
>     tableName = user
>     entityName = User
>     
>     mybatis.mapper-locations = classpath:mapper/*Mapper.xml

五、运行测试

在数据库中在的表user中，根据测试代码添加ID为1数据信息，然后启动项目。

在浏览器输入[http://localhost:8080/hello][http_localhost_8080_hello]测试

到此测试完成！！！
