整体系统采用Java中Spring ,Struts, Hibernate组成。

在Action中：

public ActionForward orgview(ActionMapping mapping, ActionForm form,HttpServletRequest request,HttpServletResponse response) {// TODO Auto-generated method stubActionForward forward = new ActionForward("strpath");HttpSession session=request.getSession();String usrid=(String) session.getAttribute("uid");BxGoodsgoods=new BxGoods(); //表名String whe_str=" where c.collectType=0 and c.userId='"+usrid+"'"; //查询的SQL语句String tableName=" BxCollectGoods as c "; //表名int dipage =1;int pageSize =10;int count= currentPage.allRecord(tableName, whe_str);int allPage = currentPage.allPage(count, pageSize);Object d=request.getParameter("d");if(d!=null)dipage=Integer.valueOf(d.toString());List list_cg = currentPage.currentPage(tableName, whe_str, dipage, pageSize, allPage);List list=new ArrayList();Iterator iter=list_cg.iterator(); while(iter.hasNext()){BxCollectGoods cg =(BxCollectGoods) iter.next();CollectGoods cgBean=new CollectGoods(); String collectname = cg.getCollectName(); String collectId = cg.getCollectId(); goods =goodsDAO.findById(cg.getCollectId()); BxUser bx_user = userDAO.findById(goods.getUserId());cgBean.setSellerName(bx_user.getUserName()); BxUser user =userDAO.findById(cg.getUserId());cgBean.setBuyId(cg.getUserId());cgBean.setCollectName(cg.getCollectName());cgBean.setCollectType(cg.getCollectType());cgBean.setRecaddTime(cg.getAddTime());cgBean.setCollectId(cg.getCollectId());cgBean.setShopPrice(goods.getShopPrice());cgBean.setGoodsName(goods.getGoodsName());cgBean.setRecId(cg.getRecId()); cgBean.setGoodsImg(goods.getGoodsThumb());list.add(cgBean);} request.setAttribute("list", list);request.setAttribute("d",dipage);request.setAttribute("count",count);request.setAttribute("allPage",allPage);request.setAttribute("pageSize",pageSize); forward.setPath("/user/goods/demo.jsp");return forward;}

在前台JSP界面中：

<mce:script type='text/javascript' src="../js/page.js" mce_src="js/page.js"></mce:script><% String d = "1"; if (request.getAttribute("d") != null){ d = request.getAttribute("d").toString(); String allPage = request.getAttribute("allPage").toString(); } String count = request.getAttribute("count").toString();%> <mce:script type="text/javascript"> <div class="page"> <div class="recordcount">　到第 <input name="" type="text" size="4" id="dp" maxlength="5" onblur="this.value=this.value.replace(/[^/d]/g,'')"> 页 <input name="" type="button" value="查看" onclick="page.collection('0')"> </div> <ul id='viewpage'></ul> <div class="recordcount">共有 <font color="red" size="3.5"><%=count %></font> 条记录</div> <mce:script type="text/javascript">page.currentPage(<%=d%>); </mce:script>

前台Page.js中：
