JAVA篇：

 public void uploadImage() {
  //获取上传图片 上传
   UploadFile uploadFile=this.getFile();
         String fileName=uploadFile.getOriginalFileName();
         String delImgName = fileName;
  //获取上传文件
  //UploadFile uf = getFile("Filedata", "mobile/setshop",DictUtil.maxImagSize,DictUtil.encoding);
     //获取上传文件的类型  如 .jpg .png.....
  String imageType=fileName.substring(uploadFile.getFileName().lastIndexOf("."),uploadFile.getFileName().length());
     String imageName=System.currentTimeMillis()+imageType;
  String rootPath =this.getSession().getServletContext().getRealPath("/upload/");
  //拼接重新生成的图片名字
  String file =rootPath+"/"+imageName;
     //重命名
  uploadFile.getFile().renameTo(new File(file));
  ServiceHandler.delFile(rootPath, delImgName);
  JSONObject urlJson = new JSONObject();
  urlJson.put("imgName", imageName);
  urlJson.put("path", file.replace(file, this.getCxt().concat("/upload/".concat(imageName))));
  this.setAttr("shop_image", file.replace(file, this.getCxt().concat("/upload/".concat(imageName))));
  renderJson(urlJson.toJSONString());
