Java Mysql客户端 Mybatis-Plus 4步快速接入

1，pom增加依赖

<dependencies>
    
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.1.0</version>
    </dependency>

</dependencies>

2，在 Spring Boot 启动类中添加 @MapperScan 注解，扫描 Mapper 文件夹：

@SpringBootApplication
    @MapperScan("com.baomidou.mybatisplus.samples.quickstart.mapper")
    public class Application {

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

    }

3，编写实体类 User.java（此处使用了 Lombok

@Data
public class User {
    private Long id;
    private String name;
    private Integer age;
    private String email;
}

4，编写Mapper包下的UserMapper接口

public interface UserMapper extends BaseMapper<User> {

}

注：不需要xml文件。

开始使用

    @Autowired
    UserMapper userMapper;

    @PostMapping("/insert")
    @Log
    public Result insert() {

        User user = new User();
        userMapper.insert(user);

        return Result.getSuccessNoData();
    }
