关于如何使用struts标签输出值为map的list

最近在一个项目中,要将一个list在客户端输出,而list里面的每个值不是bean,而是map,想好好久,想了个办法,可以实现,代码如下

  ArrayList  testList=new ArrayList();
  HashMap testMap1=new HashMap();
  testMap1.put("grade","七年级");
  testMap1.put("class","一班");
  testMap1.put("master","张三");
  testList.add(testMap1);
  HashMap testMap2=new HashMap();
  testMap2.put("grade","八年级");
  testMap2.put("class","二班");
  testMap2.put("master","张三");
  testList.add(testMap2);
  HashMap testMap3=new HashMap();
  testMap3.put("grade","九年级");
  testMap3.put("class","五班");
  testMap3.put("master","李四");
  testList.add(testMap3);

    <table border="1" cellpadding="0" cellspacing="0" bordercolor="#0033CC" name="tableList">
     <tr><td>master</td><td>class</td><td>grade</td></tr>
            <logic:iterate id="element" indexId="ind" name="testList" >
             <tr>
                   <td>
        <logic:iterate id="elementValue" indexId="idx" name="element">
       <logic:equal name="elementValue" property="key" value="master">
                    <bean:write name="elementValue" property="value"/>
                    </logic:equal>
      </logic:iterate>
      </td>
     
     
     
                     <td> <logic:iterate id="elementValue" indexId="idx" name="element">
      <logic:equal name="elementValue" property="key" value="class">
                    <bean:write name="elementValue" property="value"/>
                    </logic:equal>
     </logic:iterate>
     </td>
     
                   <td><logic:iterate id="elementValue" indexId="idx" name="element">
        <logic:equal name="elementValue" property="key" value="grade">
                    <bean:write name="elementValue" property="value"/>
                    </logic:equal>
     </logic:iterate>
       </td>
            </tr>
            </logic:iterate>
    </table>

masterclassgrade还有更好的方法,欢迎交流,第一次在blog上发文,没有排版,请多见谅!
