關於如何使用struts標籤輸出值為map的list

最近在一個項目中,要將一個list在用戶端輸出,而list裡面的每個值不是bean,而是map,想好好久,想了個辦法,可以實現,代碼如下

  ArrayList  testList=new ArrayList();  HashMap testMap1=new HashMap();  testMap1.put("grade","七年級");  testMap1.put("class","一班");  testMap1.put("master","張三");  testList.add(testMap1);  HashMap testMap2=new HashMap();  testMap2.put("grade","八年級");  testMap2.put("class","二班");  testMap2.put("master","張三");  testList.add(testMap2);  HashMap testMap3=new HashMap();  testMap3.put("grade","九年級");  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>
