struts2标签及表达式的问题

Question

<s:iterator value="personList">
    <tr>
<td>
      <s:property value="name"/>
</td>
<td>
      <s:property value="department"/>
</td>
<td>
      <s:property value="age"/>
</td> <td>
      <a href="<%=request.getContextPath()%>/modifyPersonMsg.do?bookId=${id}">修改信息</a>
      <a href="<%=request.getContextPath()%>/removePerson.do?bookId=${id}">删除</a>
</td>
     </tr>
</s:iterator>结果点击“修改信息”链接，${id}每次都无法解析，name、department、age都能显示；请教各位达人帮忙解决一下

Answer 1

前面都用struts2的标签了 超链接也用好了
<s:a href="<%=request.getContextPath()%>/modifyPersonMsg.do?bookId=%{id}">修改信息 </s:a>

Answer 2

给你个例子  仿着写  <s:url id="furl" action="student_findById">
<s:param name="student.stuId" value="stuId"></s:param>
</s:url>
<s:a href="%{furl}">update</s:a>

Answer 3

<s:url id="furl" action="student_findById">
    <s:param name="student.stuId" value="stuId"></s:param>
</s:url>
<s:a href="%{furl}">update</s:a>

Answer 4

<s:url id="furl" action="modifyPersonMsg"> 
    <s:param name="bookId">${ID}</s:param> 
</s:url> 
<s:a href="%{furl}">修改信息</s:a>
