struts 2 用s 标签 输出 list 里的 map

 这个问题纠结我好长一段时间，

还是被我找到了

  Map<String, String> map = new HashMap<String, String>();<s:iterator id="map" value="userList" status="user_state">              <s:iterator value="userList[#user_state.index]">                   Key : <s:property value="key" />                  Value : <s:property value="value" /><br>              </s:iterator>  </s:iterator>  

 
通过以上方法，即可把你的类型是list<map<String,String>>的变量userList中的东西都依次显示在页面中。  
 

 Map<Post, String> map = new HashMap<Post, String>(); <s:iterator id="map" value="userList" status="user_state">                  <s:iterator value="userList[#user_state.index]" status="s">                       Key : <s:property value="key.post_name" />                    Value : <s:property value="value" /><br>                </s:iterator>             </s:iterator>  

 Map<Post, List<Post>> map = new HashMap<Post, List<Post>>(); 

    <s:iterator id="map" value="userList" status="user_state">                  <s:iterator value="userList[#user_state.index]" status="s">                       Key : <s:property value="key.post_name" />  <br>                     Value :<br>                     <s:iterator value="value">                    <s:property value="post_name" />                    </s:iterator>                                                         </s:iterator>             </s:iterator>
