uploadify文件上传的使用

1.jsp代码

    appname=$("#appname").val();
        $("#uploadify").uploadify({
            'swf' : '<%=basePath%>/Backstage/Style/jQuery-uploadify/uploadify.swf',
            // 'script' : 'ProductAction!fileUpload.do',//后台处理的请求
            'uploader': 'AppVersionAction!fileUpload.do?appname='+appname , 
            'cancelImg' : '<%=basePath%>/Backstage/include/easyvalidator/images/vtip_arrow.png',
            'folder' : '/uplaod/temp',//您想将文件保存到的路径
            'queueID' : 'fileQueue',//与下面的id对应
            'fileObjName':'uploadify',
            'queueSizeLimit' : 5,
            'fileDesc' : '文件格式',
            'fileTypeExts' : '*.apk;*.ipa;*.png', //控制可上传文件的扩展名，启用本项时需同时声明fileDesc
            'auto' : false,
            'multi' : true,
            'simUploadLimit' : 2,
            'buttonText' : '选择文件',
            'onQueueComplete' : function(file,data,response) { 
                  picFlag = true;  
            }  
        });

    <input type="file" name="uploadify" id="uploadify" />
                <input id="appname" type="text" value="<s:property value="version.appName"/>" name="version.appName" size="30"   maxlength="32"  data-options="required:true,missingMessage:'请输入版本号'" class="easyui-validatebox" /><font color="red">&nbsp;*</font>

2.action和service

    public void addVersion() {
        String appname= getRequest().getParameter("appname");
        UploadImg upload = new UploadImg();
        try {
            /** 商品基本属性 **/

            /** 将缓存中的图片放入版本目录中 **/

            String filesext=(String) getSession().getAttribute("fileExt");
            String updateUrl=(String) getSession().getAttribute("fileName1");
            if (files != null) {
                SimpleDateFormat yearFormat = new SimpleDateFormat("yyyyMMdd");
                String folderName = Constants.versionFileSavePath + "/" + yearFormat.format(new Date()) ;
                String newFileName=appname+"."+filesext;
                for (int i = 0; i < files.size(); i++) {
                    upload.moveAndSaveFile(getRequest(), "/Upload/temp" +files.get(i), "/Upload/"+folderName,newFileName);
                }
                version.setUpdateUrl(updateUrl);
//                commodityInfo.setImageDir("/Upload/" + folderName);
            }
            getSession().removeAttribute("files");
            getSession().removeAttribute("fileName1");

            getResponse().setContentType("text/html;charset=utf-8");
