ajaxfileupload 上传成功后页面得到的返回值和后台的返回值不一样

Question

后台返回值："{'status':success,'path': }";
页面的sucess: function(data)中的data的值如图

当然我的dataType: 'json'

@ResponseBody
@RequestMapping(method = RequestMethod.POST, value = "/upload")
public void upload(@RequestParam("myfiles") MultipartFile myfiles, HttpServletRequest request,
HttpServletResponse response) throws IOException{
String filePath = UploadFile.uploadImage(Constants.ENTERPRISE_LOGO_FTP_FILE_PATH, myfiles);
DecimalFormat df = new DecimalFormat("0.00");
Double d = (myfiles.getSize())/(1024.0);
String fileSize =df.format(d);
String result = "{'status':'"+ Constants.RETURN_STATUS_SUCCESS + "','path':'" + filePath + "','fileSize':'" + fileSize + "'}";
response.setContentType("text/json");
ServletOutputStream outputStream = response.getOutputStream();
outputStream.write(result.getBytes());
outputStream.flush();
}

    $.ajaxFileUpload({
        url:'${ctx}/CorpAttachmentController/upload',
        secureuri:false,
        fileElementId: fileId,
        dataType: 'json' ,
        success: function (data){
            alert("上传！"+data);
            },error: function (data){
            alert("上传失败！"+data);
        }   });

应该是后台问题，前端后台代码贴出来看看吧
