Struts2 Flex 大文件与多文件上传

（1）下载开源的Flex上传插件:

HTML页面：

            <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0"
                width="100%" height="300px" id="file" align="middle">
                <param name="allowScriptAccess" value="sameDomain" />
                <param name="movie" value="./FlashFileUpload.swf?ver=2009041702" />
                <param name="quality" value="high" />
                <param name="wmode" value="transparent">
                <param name="FlashVars" value='fileTypeDescription=rar&fileTypes=*.*;**.rar&fileSizeLimit=30000000&totalUploadSize=102400000&uploadPage=http://127.0.0.1:9888/cooker/file/upload.htm;jsessionid=1111?username=1111'>
                <embed src="./FlashFileUpload.swf?ver=2009041702" FlashVars='fileTypeDescription=rar&fileTypes=*.*;*.rar;&fileSizeLimit=30000000&totalUploadSize=102400000&uploadPage=http://127.0.0.1:9888/cooker/file/upload.htm;jsessionid=1111?username=1111'
                    quality="high" wmode="transparent" width="100%" height="300px" name="file"
                    align="middle" allowscriptaccess="sameDomain" type="application/x-shockwave-flash"
                    pluginspage="http://www.macromedia.com/go/getflashplayer" />
            </object>

(2)struts2配置
修改struts.xml的最大上传文件大小配置

<constant name="struts.multipart.maxSize" value="100000000" />

(3)struts2 Action 这个很重要，是关键

对应的属性：

	/** 文件对象 */
	private List<File> Filedata;

	/** 文件名 */
	private List<String> FiledataFileName;
	
	/** 文件内容类型 */
	private List<String> FiledataContentType;
