IE中使用ajaxSubmit上传文件弹出下载提示框

使用jQuery的ajaxSubmit 上传文件时,在IE中会弹出下载提示框:

 页面代码:

var options = {
			   url: "<%=path%>/upload/upload",
			   type: "POST",
			   dataType:'html',
			   success:function(json) {
				   alert("json:"+json);
 },
			   error:function(er){
				   alert("er:"+er);
				   //functionChange(er.responseText);
			   }
	};
		$('#picForm').ajaxSubmit(options);

 后台代码:

/***
	 * {"fileName":"20141002125209_571slide4.jpg","path":"D:\\software\\eclipse\\workspace2\\demo_channel_terminal\\upload\\image\\20141002125209_571slide4.jpg"}
	 * @param file
	 * @param request
	 * @param response
	 * @return
	 * @throws IOException
	 */
	@ResponseBody
	@RequestMapping(value = "/upload")
	public ModelAndView upload(
			@RequestParam(value = "image223", required = false) MultipartFile file,
			HttpServletRequest request, HttpServletResponse response)
			throws IOException {
		Map map = new HashMap();
		if (ValueWidget.isNullOrEmpty(file)) {
			map.put("error", "not specify file!!!");
		} else {
			System.out.println("request:" + request);// org.springframework.web.multipart.support.DefaultMultipartHttpServletRequest@7063d827
			System.out.println("request:" + request.getClass().getSuperclass());
			// String formFileTagName=null;//"file2"
			// for( ;multi.hasMoreElements();){
			// String element=multi.nextElement();
			// formFileTagName=element;//表单中标签的名称：file标签的名称
			// // System.out.println("a:"+element+":$$");
			// break;
			// }
			String fileName = file.getOriginalFilename();// 上传的文件名
			fileName=fileName.replaceAll("[\\s]",	"");//IE中识别不了有空格的json
			// 保存到哪儿
			String finalFileName = TimeHWUtil.formatDateByPattern(TimeHWUtil
					.getCurrentTimestamp(),"yyyyMMddHHmmss")+ "_"
							+ new Random().nextInt(1000) + fileName;
			File savedFile = getUploadedFilePath(request,
					Constant2.UPLOAD_FOLDER_NAME + "/image", finalFileName,
					Constant2.SRC_MAIN_WEBAPP);// "D:\\software\\eclipse\\workspace2\\demo_channel_terminal\\ upload\\pic\\ys4-1.jpg"
			System.out.println("[upload]savedFile:"
					+ savedFile.getAbsolutePath());
			// 保存
			try {
				file.transferTo(savedFile);
			} catch (Exception e) {
				e.printStackTrace();
			}
			
			map.put("fileName", fileName);
			map.put("path", savedFile.getAbsolutePath());
			System.out.println("map:"+map);
		}
		ModelAndView modelAndView = new ModelAndView(
				new MappingJacksonJsonView(), map);
/*
 * {"fileName":"20141002125209_571slide4.jpg","path":"D:\\software\\eclipse\\workspace2\\demo_channel_terminal\\upload\\image\\20141002125209_571slide4.jpg"}
 * */
		return modelAndView;

	}

 解决方法:让action返回String,而不是ModelAndView.

修改后的action:

/***
	 * {"fileName":"20141002125209_571slide4.jpg","path":"D:\\software\\eclipse\\workspace2\\demo_channel_terminal\\upload\\image\\20141002125209_571slide4.jpg"}
	 * @param file
	 * @param request
	 * @param response
	 * @return
	 * @throws IOException
	 */
	@ResponseBody
	@RequestMapping(value = "/upload")
	public String upload(
			@RequestParam(value = "image223", required = false) MultipartFile file,
			HttpServletRequest request, HttpServletResponse response)
			throws IOException {
		String content = null;
		Map map = new HashMap();
		if (ValueWidget.isNullOrEmpty(file)) {
			map.put("error", "not specify file!!!");
		} else {
			System.out.println("request:" + request);// org.springframework.web.multipart.support.DefaultMultipartHttpServletRequest@7063d827
			System.out.println("request:" + request.getClass().getSuperclass());
			
			
			String fileName = file.getOriginalFilename();// 上传的文件名
			fileName=fileName.replaceAll("[\\s]",	"");//IE中识别不了有空格的json
			// 保存到哪儿
			String finalFileName = TimeHWUtil.formatDateByPattern(TimeHWUtil
					.getCurrentTimestamp(),"yyyyMMddHHmmss")+ "_"
							+ new Random().nextInt(1000) + fileName;
			File savedFile = getUploadedFilePath(request,
					Constant2.UPLOAD_FOLDER_NAME + "/image", finalFileName,
					Constant2.SRC_MAIN_WEBAPP);// "D:\\software\\eclipse\\workspace2\\demo_channel_terminal\\ upload\\pic\\ys4-1.jpg"
			System.out.println("[upload]savedFile:"
					+ savedFile.getAbsolutePath());
			// 保存
			try {
				file.transferTo(savedFile);
			} catch (Exception e) {
				e.printStackTrace();
			}
		
			ObjectMapper mapper = new ObjectMapper();
			
			

			map.put("fileName", "a");
			map.put("path", savedFile.getAbsolutePath());
			try {
				content = mapper.writeValueAsString(map);
				System.out.println(content);
			} catch (JsonGenerationException e) {
				e.printStackTrace();
			} catch (JsonMappingException e) {
				e.printStackTrace();
			} catch (IOException e) {
				e.printStackTrace();
			}
			System.out.println("map:"+map);
		}
//		ModelAndView modelAndView = new ModelAndView(
//				new MappingJacksonJsonView(), map);
/*
 * {"fileName":"20141002125209_571slide4.jpg","path":"D:\\software\\eclipse\\workspace2\\demo_channel_terminal\\upload\\image\\20141002125209_571slide4.jpg"}
 * */
		return content;
