DAO層的代碼分頁(yè)代碼：
public PageModel findByPageModel(String hql,PageModel pm) {
  pm.setTotalCount(this.getHibernateTemplate().find(hql).size());
  pm.setGoToHref(ServletActionContext.getRequest().getServletPath().replace("/",""));
  int totalCount = pm.getTotalCount();
  int pageSize = pm.getPageSize();
  int totalPage = (totalCount+pageSize-1)/pageSize ;
  int currentPage = pm.getCurrentPage() ;
  pm.setTotalPage(totalPage);
  int offset = (currentPage-1)*pageSize;
  pm.setList(this.getSession().createQuery(hql).setFirstResult(offset).setMaxResults(pageSize).list());
  return pm;
 }

分頁(yè)的JAVABEAN:
public class PageModel {
 private int currentPage;
 private int pageSize;
 private int totalCount;
 private int totalPage;
 private List list ;
 private String goToHref;
 
 public int getCurrentPage() {
  if(currentPage<=0) currentPage=1;
  return currentPage;
 }
 public void setCurrentPage(int currentPage) {
  this.currentPage = currentPage;
 }
 public int getPageSize() {
  if(pageSize<=0) pageSize=10;
  return pageSize;
 }
 public void setPageSize(int pageSize) {
  this.pageSize = pageSize;
 }
 public int getTotalCount() {
  return totalCount;
 }
 public void setTotalCount(int totalCount) {
  this.totalCount = totalCount;
 }
 public int getTotalPage() {
  return totalPage;
 }
 public void setTotalPage(int totalPage) {
  this.totalPage = totalPage;
 }
 public List getList() {
  return list;
 }
 public void setList(List list) {
  this.list = list;
 }
 public String getGoToHref() {
  return goToHref;
 }
 public void setGoToHref(String goToHref) {
  this.goToHref = goToHref;
 }
}

JSP頁(yè)面：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<link rel="stylesheet" type="text/css" href="<%=basePath %>findByHql/pagingBar/css/pagingBar.css">

 <input type="button" class="firstPage commonPage"  alt="首頁(yè)"   title="首頁(yè)"/>

 <input type="button" class="nextPage commonPage"   alt="下一頁(yè)" title="下一頁(yè)"/>
 <input type="button" class="lastPage commonPage"   alt="尾頁(yè)"   title="尾頁(yè)" />
 
 <input type="hidden" id="currentPage" value="${requestScope.pm.currentPage }" />
 <input type="hidden" id="totalPage" value="${requestScope.pm.totalPage }" />
 <input type="hidden" id="goToHref" value="${requestScope.pm.goToHref }" />
 
 <span class="cp">當(dāng)前第${requestScope.pm.currentPage }頁(yè)</span>
 <span class="tc"> 相關(guān)資訊:${requestScope.pm.totalCount }條</span>
 <span class="ps">每頁(yè)${requestScope.pm.pageSize }條 </span>
 <span class="tp">共${requestScope.pm.totalPage}頁(yè)</span>

<script type="text/javascript" src="<%=basePath%>js/jquery.js"></script>
<script type="text/javascript">
 (function($) {
  var currentPage = parseInt($('#currentPage').val());
  var totalPage = parseInt($('#totalPage').val());
  var toHref = $('#goToHref').val();
  $('.firstPage').bind('click', function() {
   goToHref(1);
  });
  $('.nextPage').bind('click', function() {
   if (currentPage >= totalPage)
    goToHref(totalPage);
   else
    goToHref(currentPage + 1);
  });
  $('.beforePage').bind('click', function() {
   if (currentPage <= 1)
    goToHref(1);
   else
    goToHref(currentPage - 1);
  });
  $('.lastPage').bind('click', function() {
   goToHref(totalPage);

CSS:下面有幾張圖片需要自己找...
/*點(diǎn)擊欄*/
.commonPage{
 width: 16px;
 height: 16px;
 border: none;
 cursor: pointer;
}
.firstPage{
 background: url("../images/page-first.png") no-repeat;
}

.nextPage{
 background: url("../images/page-next.png") no-repeat;
}

.beforePage{
 background: url("../images/page-prev.png") no-repeat;
}

.lastPage{
 background: url("../images/page-last.png") no-repeat;
}

/*顯示欄*/
.cp,.tc,.ps,.tp{
 font-size: 14px;
}

在action中調(diào)用DAO層的方法，給currentPage和pageSize設(shè)置初始值,然后就返回一個(gè)list到你分頁(yè)的頁(yè)面迭代,以后就直接嵌套在分頁(yè)頁(yè)面中就行
