</table> ssh? 数据库 jsp 读取数据 显示
[解决办法]

<s:iterator value="#request.selectempinfo" id="info">
   <tr>
       <td><s:property value="#info.staffCode"/></td>
       <td><s:property value="#info.workDate"/></td>
       <td><s:property value="#info.week"/></td>
       <td><s:property value="#info.workStart"/></td>
       <td><s:property value="#info.workEnd"/></td>
   </tr>
 </s:iterator>

[解决办法]

<s:iterator value="#request.selectempinfo" var="info">
   <tr>
       <td><s:property value="info.staffCode"/></td>
       <td><s:property value="info.workDate"/></td>
    <td><s:property value="info.week"/></td>
    <td><s:property value="info.workStart"/></td> 
 
    <td><s:property value="info.workEnd"/></td>
   </tr>
   </s:iterator>

注:info.后面的字段与EmployeeInfo中的相对应
[解决办法]

引用:

Java code?123456789<s:iterator value="#request.selectempinfo" var="info"> <tr> <td><s:property value="info.staffCode"/></td> <td><s:property value="info.workDate"/></td> ……

就是这样
[解决办法]
你调试的时候 List<EmployeeInfo> selectempinfo= empService.queryInfo();这个里面有值没有
