基于Struts2的通用文件上传实现（二）

四、Action配置

<action name="attachList" class="attachAction">
	<result name="success" type="tiles">attach.list</result>
</action>

<action name="upload" class="attachAction">
	<result name="input" type="tiles">attach.add</result>
	<result name="success" type="tiles">window.close</result>
</action>

<action name="attachDelete" class="attachAction">
	<result name="success" type="redirect">${url}</result>
</action>

<action name="download" class="attachAction">
	<result name="success" type="stream">
		<param name="contentType">application/octet-stream</param>
		<param name="contentDisposition">attachment;filename=${uploadFileName}</param>
		<param name="bufferSize">4096</param>
		<param name="inputName">targetFile</param>
	</result>
</action>

 

五、列表JSP页面源代码

<cjm:toolBar>
	<cjm:toolBarButton title="上传附件" width="80" onclick="openUploadWindow('upload.action?attach.entityName=%{attach.entityName}&attach.entityId=%{attach.entityId}&attach.refName=%{attach.refName}&attach.path=%{attach.path}&allowTypes=%{allowTypes}&maxSize=%{maxSize}')" imgSrc="images/toolbar/add.gif"/>
	<cjm:toolBarButton title="删除" onclick="deleteFormRow(document.all['frmAttachList'], 'chk_o_', 'attachDelete.action')" imgSrc="images/toolbar/delete.gif"/>
</cjm:toolBar>
	
<s:form name="frmAttachList">
	<s:hidden name="attach.path" value="%{attach.path}"/>
	<s:hidden name="attach.entityName" value="%{attach.entityName}"/>
	<s:hidden name="attach.entityId" value="%{attach.entityId}"/>
	<s:hidden name="attach.refName" value="%{attach.refName}"/>
	<s:hidden name="allowTypes" value="%{allowTypes}"/>
	<s:hidden name="maxSize" value="%{maxSize}"/>
	
	<table border="0" cellspacing="0" cellpadding="2" class="list" align="center">
		<tr class="top" height="25">
	    	<td width="25"><input type="checkbox" onclick="checkAll(this)"></td>
	    	<td>附件名称</td>
	    	<td width="100">文件大小</td>
	    	<td width="150">文件类型</td>
	    	<td width="130">创建时间</td>
	    	<td width="50">下载</td>
	  	</tr>
	  	
	  	<s:iterator value="attachList" id="attach" status="st">
	  		<tr <s:if test="#st.odd">class="bg1"</s:if><s:else>class="bg2"</s:else> >
	  			<td align="center"><input type="checkbox" name="chk_o_<s:property value='#st.count'/>" value="<s:property value='#attach.id'/>"></td>
	  			<td align="left"> <s:property value="#attach.name"/></td>
	  			<td align="center"> <s:property value="#attach.fileSize"/> K</td>
	  			<td align="center"> <s:property value="#attach.contentType"/></td>
	  			<td align="center"> <s:date name="#attach.createDate" format="yyyy-MM-dd HH:mm"/></td>
	  			<td align="center"><a href="download.action?attach.id=<s:property value="#attach.id"/>">下载</a></td>
	  		</tr>
	  	</s:iterator>
	</table>
</s:form>

 

六、附件添加JSP页面源代码

<s:form action="upload" name="frmUpload" method="post" enctype="multipart/form-data">
	<s:hidden name="attach.path" value="%{attach.path}"/>
	<s:hidden name="attach.entityName" value="%{attach.entityName}"/>
	<s:hidden name="attach.entityId" value="%{attach.entityId}"/>
	<s:hidden name="attach.refName" value="%{attach.refName}"/>
	<s:hidden name="allowTypes" value="%{allowTypes}"/>
	<s:hidden name="maxSize" value="%{maxSize}"/>
	
	<br>
	<s:file name="upload" label="选择文件" size="55" cdata=" dataType='Require' msg='必填项'"/>
</s:form>

 

七、范例

attachList.action?attach.entityName=Organization&attach.entityId=${org.orgId}&attach.refName=attachment&attach.path=/sim&allowTypes=txt&maxSize=10485760

可以到我的博客 http://chenjumin.iteye.com 查阅《基于Struts2的通用文件上传实现》这篇文章的一、二两章，从中你可以找到答案。看download这个Action的配置和源代码就知道了。

怎么实现下载列表呢？比如说是在一个界面有一个下载列表，用户可以选择某个进行下载。
