angularjs – Spring-boot：不存在所需的请求部分’file’

春季启动

@ApiOperation(value = "Post new file")
  @RequestMapping(value = "/",method = RequestMethod.POST)
  public String handleFileUpload(@RequestParam("file") MultipartFile file,@RequestParam (value = "accesstoken",required = true) String accessToken,RedirectAttributes redirectAttributes) throws Exception{
      tokenService.verifyAdmin(accessToken);

      storageService.store(file);
      return "You successfully uploaded " + file.getOriginalFilename() + "!";
  }

StorageService.store

@Override
  public void store(MultipartFile file) {
      try {
          if (file.isEmpty()) {
            throw new StorageException("Failed to store empty file " + file.getOriginalFilename());
           }
           Files.copy(file.getInputStream(),this.rootLocation.resolve(file.getOriginalFilename()));
      } catch (IOException e) {
  throw new StorageException("Failed to store file " + file.getOriginalFilename(),e);
     }
  }
