ExtJS 上传后 下载提示的处理
1.首先是Struts.xml的配置

<action name="uploadexc" method="uploadExcel" >   <interceptor-ref name ="fileUploadStack" ><!-- <param name="allowedTypes">xls,xlsx</param>  --> <param name="maximumSize">20000000000</param> </interceptor-ref> <result type='json'><param name="contentType">text/html</param>  <param name="excludeProperties">upload,userWorkTimeSer</param></result></action>   

2.action的写法

/** * 上传Excel * @return */public String uploadExcel(){try {Date d = new Date();          System.out.println("uploadFileName = "+this.uploadFileName);          //upload --  wapps 下面的文件夹,用来存放图片          String toSrc = ServletActionContext.getServletContext().getRealPath("upload")+"/"+d.getTime()+getFileExp(this.uploadFileName);  //使用戳作文件名          System.out.println("toFile= "+toSrc);          File toFile = new File(toSrc);          writeFile(this.upload,toFile);          userWorkTimeSer.saveExcelWorkTime(upload);} catch (Exception e) {e.printStackTrace();}        return SUCCESS;  }

2.JS的写法

this.uploadform.getForm().submit({url: 'uploadexc.action',//waitMsg: 'Uploading your photo...',success: function(response){},failure:function(response){//上传完后,返回失败,Ext.getCmp('upwindow').hide();Ext.getCmp('userWorkTimeGrid').getStore().reload();}             });

在Struts2 中,上传完成后,返回的JSON时,提示下载,用上面的配置后,不会提示了,Ajax返回的居然是failure,很是奇怪,使用fileBug查看也是正常的,不过算是解决了!呵呵
