jsp页面：

<%@ page contentType="text/html; charset=UTF-8"%><%@ taglib prefix="s" uri="/struts-tags"%><html><head></head><body><h1>数据展示</h1><h2>   <table border="1" width="50%"  cellspacing="0" cellpadding="0">               <s:iterator value ="#session.tZhengtiDataList" var="mycontent" status="indexValue">         <tr>     <td><s:property value="#mycontent.statisticTime" /></td>      <td><s:property value="#mycontent.area"/></td>         <td><s:property value="#mycontent.insurBody"/></td>         <td><s:property value="#mycontent.preminum"/></td>     </tr>     </s:iterator>      </table>   </h2></body></html>

action页面：
