    @RequestMapping(value = "/uploadGPS", method = RequestMethod.POST)
    @ResponseBody
    public Object uploadGPS(String userAccount, String token, String fileName, String fileLength, HttpServletRequest request) {
        Map<String, MultipartFile> multiRequest = ((MultipartHttpServletRequest)request).getFileMap();
        MultipartFile multipartFile = multiRequest.get("file");
        CommonsMultipartFile cf= (CommonsMultipartFile)multipartFile;
        DiskFileItem fi = (DiskFileItem)cf.getFileItem();
        File file = fi.getStoreLocation();
