struts2根本运用

1、打印迭代顺序
 <s:iterator value="allltZhutiFiles" id="v" status="a">		
    <tr>
	<td class="edit_td_title">${a.index+1 } &nbsp;&nbsp;楼：</td>
	<td colspan="5" class="edit_td_input">
		${v.fileTitle}
	</td>
   </tr>
</s:iterator>


2、多层迭代
<!-- 两层迭代分别显示回复和回复附件 -->
<s:iterator value="allltHuifuJbxxs" id="v" status="a">		
	<tr>
		<td valign="top" class="edit_td_title" width="12%">
			${a.index+1 } &nbsp;&nbsp;楼：
			${v.submitPersonName} &nbsp;
		</td>
		<td colspan="7" class="edit_td_input">
			<!-- 回复类容 -->
			${v.contentDesc} <br />
			
			<!-- 判断是否存在附件 -->
			<s:if test="#v.ltHuifuFiles.size() > 0">
				<font color="#0033FF">附&nbsp;&nbsp;&nbsp;件：</font>
				<s:iterator value="#v.ltHuifuFiles" id="file">	
					<a href="${ctx}${file.fileAddr}" style="text-decoration: underline;" target="_blank">${file.fileTitle}</a>
					<br />
					<br />
				 	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
				</s:iterator>
			</s:if>
		</td>
	</tr>
</s:iterator>
