      RestResultResponse<FileUploadVO> handleFileUpload(@RequestParam("multipartFile") MultipartFile multipartFile);

service:
     @PostMapping(value = "/uploadFile")
    public ResponseDTO<FileUploadVO> uploadFileFegin(@RequestParam("multipartFile") MultipartFile multipartFile) {
        return  ResponseUtils.success(azureBlobUtil.upload(multipartFile));
    }

Can help me give me some suggest or idea improve it？

HTTP error code 411 indicates that a file length is required and either not present or incorrect. https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/411

I recommend looking into that status code first.
