1、目录结构
2、新增配置
@Configuration
//扫描mapper接口所在的包
@MapperScan("com.zyz.mybatisplus.mapper")
public class MyBatisPlusConfig {
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor(){
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
return interceptor;
}
}
3、编写测试类
@SpringBootTest
public class MyBatisPlusPluginsTest {
@Autowired
private UserMapper userMapper;
@Test
public void testPage(){
Page<User> page = new Page<>(2,3);
userMapper.selectPage(page,null);
System.out.println(page.getRecords());
System.out.println(page.getPages());
System.out.println(page.getTotal());
System.out.println(page.hasNext());
System.out.println(page.hasPrevious());
}
}
4、测试结果
5、数据库中的表
