Spring 我收到错误java.io.EOFException：尝试获取多部分文件时，套接字上意外读取了EOF

我有js功能，可以上传文件和其他数据

function uploadFormData(){
            var oMyForm = new FormData();
            oMyForm.append("file", file2.files[0]);
            oMyForm.append("resolutionName", document.getElementById("ruling-name").value);
            $.ajax({
                url: '/add',
                data: oMyForm,
                dataType: 'text',
                processData: false,
                contentType: false,
                type: 'POST',
                success: function(data){ 
                }
            });
        }

我有一个spring引导控制器，它有接收数据的方法

@RequestMapping(value = "/add", method = RequestMethod.POST)
    public ModelAndView add(MultipartHttpServletRequest request) {

        Iterator<String> itr =  request.getFileNames();
        MultipartFile mpf = request.getFile(itr.next());    
        try {
            UploadedFile ufile = new UploadedFile();
            ufile.length = mpf.getBytes().length;
            ufile.bytes= mpf.getBytes();
            ufile.type = mpf.getContentType();
            ufile.name = mpf.getOriginalFilename();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return new ModelAndView("index");
    }

到

但我犯了个错误
