/**
     * 上传头像
     */
    @RequestMapping(value="uploadPhotoHead")//, produces = {"application/json;charset=UTF-8"}
    @ResponseBody
    public String uploadPhotoHead(HttpServletRequest request,Integer userId){
        Result<String> result=new Result<>(false);
        try {
            MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;

            result.setMessage(e.getMessage());

UserBizServiceImpl实现类

@Override

    public Result<String> uploadPhotoHead(MultipartFile file,Integer userId) {
        Result<String> result=new Result<>(false);
        User user=userService.findByPrimaryKey(userId);
        if(user==null){
            result.setMessage("用户不能为空");
            result.setSuccess(false);
            return result;
        }
        String date=new SimpleDateFormat("yyyyMMdd").format(new Date());
        File file2=new File(file.getOriginalFilename());
        try {
            file.transferTo(file2);
            ftpUtils.connect("", CommonConstant.addr, CommonConstant.port, CommonConstant.username, CommonConstant.password);
            if(ftpUtils.isExistDir(date)){
                    uploadPicture( file2, date);
            }else{
                ftpUtils.mkDir(date);
                uploadPicture( file2, date);
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }finally {
            if(file2.exists()){
                file2.delete();
            }
        }
        user.setPhotoHead("/"+date+"/"+file.getOriginalFilename());
        userService.updateByPrimaryKeySelective(user);
        result.setMessage("上传成功");
        result.setSuccess(true);
        return result;
    }

    private void uploadPicture( File file2, String date) throws Exception {
        ftpUtils.changeWorkingDirectory(date);
        ftpUtils.upload(file2);
        ftpUtils.closeFtp();
    }
