below the tab can be used, the need to call one line of code is added to the dao layer ServiceImpl
PageHelper.startPage (pageNum, the pageSize);
@Override
public List <the Syslog> selall (pageNum Integer, Integer the pageSize) {
PageHelper.startPage (pageNum, the pageSize);
return iSysLogDao.selAll ();

Controller layer needs to store information on this subject PageInfo
@RequestMapping("/show")
public ModelAndView show(@RequestParam(defaultValue = "1",required = true) Integer pageNum,@RequestParam(defaultValue = "10",required = true) Integer pageSize){
ModelAndView modelAndView=new ModelAndView("syslog-list");
List<Syslog> syslogList=iSysLogService.selAll(pageNum,pageSize);
PageInfo pageInfo=new PageInfo(syslogList);
modelAndView.addObject("pageInfo",pageInfo);
ModelAndView return;

PageInfo encapsulates paging information can be used directly,
<div class="box-tools pull-right">
<ul class="pagination">
<li><a href="${pageContext.request.contextPath}/sysLog/show?pageNum=1&pageSize=${pageInfo.pageSize}" aria-label="Previous">首页</a></li>
<li><a href="${pageContext.request.contextPath}/sysLog/show?pageNum=${pageInfo.pageNum-1}&pageSize=${pageInfo.pageSize}">上一页</a></li>
<c:forEach begin="1" end="${pageInfo.pages}" var="pageNum">
<li><a href="${pageContext.request.contextPath}/sysLog/show?pageNum=${pageNum}&pageSize=${pageInfo.pageSize}">${pageNum}</a></li>
</c:forEach>
<li><a href="${pageContext.request.contextPath}/sysLog/show?pageNum=${pageInfo.pageNum+1}&pageSize=${pageInfo.pageSize}">下一页</a></li>
