baomidou.mybatisplus分页插件使用

Posted 2023-05-03

参考技术A 1、jar包引用
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.1.0</version>
</dependency>

2、java插件配置
@Configuration
public class MybatisConfig
@Bean
public PaginationInterceptor paginationInterceptor()
return new PaginationInterceptor();



3、service实现使用
public List<UserMessageDTO> getListPage(Long userId, Long pageNum, Long pageSize)

if (ObjectUtils.isEmpty(userId))
throw new CommonException("无用户信息,获取用户消息数据失败");

pageNum = pageNum != null ? pageNum : CommonEnum.PageInfoEnum.PAGE_NUM.getValue();
pageSize = pageSize != null ? pageSize : CommonEnum.PageInfoEnum.PAGE_SIZE.getValue();

Page<UserMessageDO> page = new Page<>();
List<UserMessageDO> list = userMessageMapper.getListPage(page, userId);
page.setRecords(list);

return null;


4、mapper使用
public interface UserMessageMapper

int insert(UserMessageDO userMessageDO);

List<UserMessageDO> getListPage(Page<UserMessageDO> page, Long userId);
