有时候需要根据条件查询得出的数据较多，需要分页显示到页面上。这时点击下一页就不方便每次带查询条件在数据库中分页。可以在list中进行分页。
page的model类：
public class Page { private Integer currentPage;//当前页 private int pageSize;//每页显示记录条数 private int totalPage;//总页数 private List<?> dataList;//每页显示的数据 private int star;//开始数据 public Integer getCurrentPage() { return currentPage; } public void setCurrentPage(Integer currentPage) { this.currentPage = currentPage; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } public int getTotalPage() { return totalPage; } public void setTotalPage(int totalPage) { this.totalPage = totalPage; } public List<?> getDataList() { return dataList; } public void setDataList(List<?> dataList) { this.dataList = dataList; } public int getStar() { return star; } public void setStar(int star) { this.star = star; } } 控制层：
@RequestMapping("fenye.do") public String fen(Page page,HttpServletRequest request){ try { //查询出的list数据 List<Data> showdata=loginService.selectyichall(); //刚开始的页面为第一页 if (page.getCurrentPage() == null){ page.setCurrentPage(1); } else { page.setCurrentPage(page.getCurrentPage()); } //设置每页数据为十条 page.setPageSize(10); //每页的开始数 page.setStar((page.getCurrentPage() - 1) * page.getPageSize()); //list的大小 int count = showdata.size(); //设置总页数 page.setTotalPage(count % 10 == 0 ? count / 10 : count / 10 + 1); //对list进行截取 page.setDataList(showdata.subList(page.getStar(),count-page.getStar()>page.getPageSize()?page.getStar()+page.getPageSize():count)); //设置作用域 request.setAttribute("paging", page); return "add/show.jsp"; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); return "mistake.jsp"; } } jsp页面：
<script type="text/javascript" language="javascript"> function goPage(page){ location.href="fenye.do?currentPage=" rel="external nofollow" +page; } </script> <div> <table align="center" cellspacing="1" > <c:forEach items="${paging.dataList }" var="upl"> <tr> <td align="center">${upl.name1 }</td> <td align="center">${upl.name2 }</td> <td align="center">${upl.name3 }</td> </tr> </c:forEach> </table> </div> <div style="text-align:center; margin-top:10px;color: white;" id="venderfen"> <c:if test="${paging.totalPage > 0}"> 当前第 ${paging.currentPage } 页/共 ${paging.totalPage} 页 </c:if> <c:if test="${paging.totalPage > 1}"> <c:choose> <c:when test="${paging.currentPage==2 && paging.totalPage==2}"> <a onclick="goPage(1)">首页</a> <a onclick="goPage(${paging.currentPage-1})">上一页</a> </c:when> <c:when test="${paging.currentPage==1}"> <a onclick="goPage(${paging.currentPage+1})">下一页</a> <a onclick="goPage(${paging.totalPage})">末页</a> </c:when> <c:when test="${paging.currentPage==paging.totalPage}"> <a onclick="goPage(1)">首页</a> <a onclick="goPage(${paging.currentPage-1})">上一页</a> </c:when> <c:otherwise> <a onclick="goPage(1)">首页</a> <a onclick="goPage(${paging.currentPage-1})">上一页</a> <a onclick="goPage(${paging.currentPage+1})">下一页</a> <a onclick="goPage(${paging.totalPage})">末页</a> </c:otherwise> </c:choose> </c:if> 共 ${paging.total} 条 </div> StringBuilder sb = new StringBuilder(); sb.append("SELECT distinct(m.time) "); sb.append(" from tbl_monitor m left join tbl_variable v on m.variable = v.id "); sb.append(" left join tbl_variable_group g on v.variable_group = g.id "); sb.append(" where v.active = true and g.active=true "); //sb.append(" AND m.variable in " + variableIds); sb.append(" AND exists ( select vtemp.id from tbl_variable vtemp where vtemp.selected=true and vtemp.id=m.variable)"); sb.append(" AND m.time between " + beginTime + " AND " + endTime ); sb.append(" order by m.time asc"); Query query = em.createNativeQuery(sb.toString()); //满足搜索条件的所有的时间的条数 int total = query.getResultList().size(); tableView.setTotal(total); tableView.setTotalPage(total % page.getPageSize() == 0 ? total / page.getPageSize() : (total / page.getPageSize()) + 1); query.setFirstResult(from); query.setMaxResults(offset); timeList = query.getResultList(); 以上就是本文关于java中对list分页并显示数据到页面实例代码的全部内容，希望对大家有所帮助。感兴趣的朋友可以继续参阅本站其他相关专题，如有不足之处，欢迎留言指出。感谢朋友们对本站的支持！
