mybatis-plus spirng boot

只添加mysql driver 不需要再添加mybatis framework

 <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.1</version>
        </dependency>

 

 

 

 

@Mapper
public interface UserDao extends BaseMapper<User> {
}

 

 

 <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>

lombok可以快速的帮助我们创建实体类，会帮我们实现getter和setter方法 

@Data
public class User {
    private Long id;
    private String username;
    private String password;


}

 

 分页

//添加拦截器
@Configuration
public class MpConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor(){
        MybatisPlusInterceptor i = new MybatisPlusInterceptor();
        //添加具体的拦截器
        i.addInnerInterceptor(new PaginationInnerInterceptor());
        return i;
    }
}
