如下的方法里面参数 file.getOriginalFilename() 为null 这是为什么呀，前台的js和上面的链接类似

@ResponseBody
    @RequestMapping(value = "import", method = RequestMethod.POST)
    public Result importFile(@RequestParam MultipartFile file, Model model, HttpServletRequest request){
        String ret = "";
 
 
        return new Result(true).data(ret);
    }
