IE8+SpringMVC文件上传防止JSON下载

今天在IE8测试文件上传的时候发现总是提示下载，原因是上传接口返回的是JSON，通过以下修改就可以保证返回是json并且不会出现下载的情况：

同时适用于当设置spring 视图解析器的时候，不能去掉@responseBody的问题

@RequestMapping(value = "/batchUpload", method = RequestMethod.POST,produces = "text/json;charset=UTF-8")  @ResponseBody  public Object batchUpload(@RequestParam String orderId, @RequestParam("file") MultipartFile file, httpservletResponse response) {    response.setHeader("Cache-Control", "no-cache");    response.setHeader("X-Frame-Options", "SAMEORIGIN");    response.setHeader("Access-Control-Allow-Origin", "*");        String filePath = fileUploadService.upload(file);    Map result = new HashedMap();    if (filePath == null) {      result.put("status", 0);    } else {      result.put("status", 1);      result.put("filePath", filePath);    }    return JSON.toJSONString(result);  }
