freemarker模板+hibernate分页问题，各位前辈帮帮忙啊

Question

System.out.println("sdfasdfsssssssssssssss");
String pagenum = request.getParameter("page");
List list=yd.showAllYh();
request.getSession().setAttribute("list", list);
int totalrecord=list.size();
Pager pagex=new Pager().getpage(pagenum, totalrecord);
int pagetotalpage=new Pager().getpage(pagenum, totalrecord).totalp;
request.getSession().setAttribute("pagex", pagex);
request.getSession().setAttribute("pagetotalpage", new Integer(pagetotalpage));
final String hql="from Yh";
final int x=(pagex.page-1)*pagex.pagesize;
final int y=pagex.pagesize;
List listfy=yd.showx(hql, x, y);
System.out.println(list.size());
request.getSession().setAttribute("listfy", listfy);
List l=(List)request.getSession().getAttribute("listfy");
System.out.println("adfadfasd"+l.size());

return mapping.findForward("yh_list");
上面是action 跳转和分页代码，跳转到页面显示异常
Expression listfy is undefined on line 13, column 14 in list.ftl.
The problematic instruction:
----------
==> list listfy as one [on line 13, column 7 in list.ftl]
----------Java backtrace for programmers:
----------
freeer.core.InvalidReferenceException: Expression listfy is undefined on line 13, column 14 in list.ftl.

要疯了！给位给想想办法

Answer 1

<html>
  <body>
<title>显示页面</title>
    <table border="1">
<tr>
       <td>编号</td>
       <td>姓名</td>
       <td>密码</td>
       <td>删除</td>
       <td>修改</td>
       <td>详细信息</td>
      </tr>
      <#list listfy as one>
      <tr>
       <td>${one.id}</td>
       <td>${one.nameone}</td>
       <td>${one.passwordone}</td>
<td><a href="p_delete.do?tid=${one.id}">删除</a></td>
<td><a href="p_update1.do?tid=${one.id}">修改</a></td>
<td><a href="p_point.do?tid=${one.id}">显示详情</a></td>
      </tr>
     </#list> 
   
</table>
  </body>  
</html>这里是ftl模板代码

Answer 2

 通过这个异常看来   Expression listfy is undefined    说明listfy未定义   你再仔细看下你的代码。
