Spring boot、mysql分页

第一种：

实现层:

@Override
public PageData inviteLogPage(Map params) {
params.put(“corpId”,SecurityUser.getUser().getCorpId());
params.put(“page”, (Long.valueOf(params.get(“page”).toString()) - 1) * Long.valueOf(params.get(“limit”).toString()));
List pageList = lhTlCorpInviteDao.selectInviteLogPageList(params);
long total = lhTlCorpInviteDao.getInviteLogCount(params);
Page page = new Page(Long.valueOf(params.get(“page”).toString()), Long.valueOf(params.get(“limit”).toString()));
page.setRecords(pageList);
page.setTotal(total);
return getPageData(page, CorpInviteDto.class);
}

Mapper层：

/**
*
* @return
*/
List selectInviteLogPageList(@Param(“params”) Map params);

Mapper.xml：

select distinct inv.id,res.RESUME_NAME as resumeName,stu.STUDENT_NAME as stuName,inv.id as id, inv.IS_VIEWED as isViewed,inv.IS_ACCEPT as isAccept,inv.IS_COMPLITE as isComplite,inv.INTERVIEW_DATE as interviewDate,tj.JOB_NAME as jobName,tj.id as jobId from lh_tl_corp_invite inv LEFT JOIN lh_tm_jobs tj ON tj.`ID` = inv.`JOB_ID` LEFT JOIN lh_tm_stu_resume res ON inv.RESUME_ID = res.ID LEFT JOIN lh_tm_student stu ON res.STUDENT_ID = stu.ID where 1=1 and inv.DEL_FLAG = 0 and inv.CORP_ID = #{params.corpId} and stu.STUDENT_NAME like CONCAT('%',#{params.name},'%') LIMIT ${params.page},${params.limit}

第二种：

实现层：

/**
* 列表
* @param params
* @return
/
@Override
public PageResult findList(Map params){
Map map = new HashMap<>();
map.put(“page”,((Integer.parseInt(params.get(“page”).toString()))-1)(Integer.parseInt(params.get(“limit”).toString())));
map.put(“limit”,(Integer.parseInt(params.get(“limit”).toString())));
List list = baseMapper.findList(map, params);
//获取数据总条数
Long count = baseMapper.getTotal(params);
return PageResult.builder().data(list).code(0).count(count).build();
}

Mapper层：

*/
List findList(@Param(“pageParam”)Map page, @Param(“p”) Map params);

Mapper.xml
