我想将表单中的文件上传到Spring Boot API端点.

UI是用React编写的:

export function createExpense(formData) {
  return dispatch => {
    axios.post(ENDPOINT,
      formData, 
      headers: {
        'Authorization': //...,
        'Content-Type': 'application/json'
      }
      ).then(({data}) => {
        //...
      })
      .catch(({response}) => {
        //...
      });
    };
}

  _onSubmit = values => {
    let formData = new FormData();
    formData.append('title', values.title);
    formData.append('description', values.description);
    formData.append('amount', values.amount);
    formData.append('image', values.image[0]);
    this.props.createExpense(formData);
  }

这是java端代码:

@RequestMapping(path = "/{groupId}", method = RequestMethod.POST)
public ExpenseSnippetGetDto create(@RequestBody ExpensePostDto expenseDto, @PathVariable long groupId, Principal principal, BindingResult result) throws IOException {
   //..
}

但是我在java方面得到了这个例外:
