另外可参考这篇文章：http://www.struts2.org/ajax-file-upload-in-struts2-using-ajax-file-upload-plugin/

在http://ajax-file-upload-struts2.googlecode.com/files/AjaxFileUpload-0.03.zip 下载包文件

把jar文件加入到 WEB-INF/lib下面，在pom.xml中加入：

Xml代码

<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>net.sf.json-lib</groupId>
<artifactId>json-lib</artifactId>
<version>2.0</version>
<classifier>jdk15</classifier>
</dependency>

<dependency>
	<groupId>commons-fileupload</groupId>
	<artifactId>commons-fileupload</artifactId>
	<version>1.2</version>
</dependency>
<dependency>
	<groupId>commons-io</groupId>
	<artifactId>commons-io</artifactId>
	<version>1.3.1</version>
</dependency>
<dependency>
	<groupId>net.sf.json-lib</groupId>
	<artifactId>json-lib</artifactId>
	<version>2.0</version>
	<classifier>jdk15</classifier>
</dependency>

在所在的jsp页面如下写法：

Html代码

<%@tagliburi="http://www.davidjc.com/taglibs"prefix="djc"%>
<head>
...
<djc:head/>
...
</head>
<body>
...
<djc:ajaxfileuploadformaction="demo"dobefore=""doafter=""/>
...
</body>

<%@ taglib uri="http://www.davidjc.com/taglibs"     prefix="djc"     %>
<head>
	...
	<djc:head />
	...
</head>
<body>
	...
	<djc:ajaxfileuploadform action="demo" dobefore="" doafter="" />
	...
</body>

配置struts.xml文件：

Xml代码

<packagename="ajaxfileupload"namespace="/"extends="ajaxfileupload-default">
<actionname="demo"class="com.davidjc.ajaxfileupload.action.Demo">
<interceptor-refname="fileUploadStack"/>
<resultname="success"type="httpheader">
<paramname="status">200</param>
</result>
</action>
</package>

<package name="ajaxfileupload" namespace="/" extends="ajaxfileupload-default">
	<action name="demo" class="com.davidjc.ajaxfileupload.action.Demo">
		<interceptor-ref name="fileUploadStack" /> 
		
		<result name="success" type="httpheader">
			<param name="status">200</param>
		</result>
	</action>
</package>

扩展 action com.davidjc.ajaxfileupload.action.FileUpload

Java代码
