通过休息接收输入流

Question

我想通过休息发送文件。正如一些帖子所指出的那样，它应该作为输入流发送，因为文件的大小可能相当大（例如数百MB）。客户端示例如下所示：

@PostMapping(value = "/app-server/file", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    public ResponseEntity<String> saveFile(@RequestBody HttpServletRequest request) throws Exception {

        /* some code here */
        return new ResponseEntity<>("fileKey", HttpStatus.CREATED);
    }

休息控制器方法：

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'multipart/form-data;boundary=1509983827081;charset=UTF-8' not supported

例外：

<UseIIS>False</UseIIS>

我无法找到错误是在客户端，服务器端还是两者都有。
