我正在尝试编写一个spring mvc方法,它可以接收multipart/form或transfer-encoding chunked文件上传.我可以编写一个单独的方法来处理每种类型,但我想用相同的方法来做,所以我可以使用相同的REST POST uri,例如:

http://host:8084/attachments/testupload

到目前为止,这是我最好的尝试:

@RequestMapping(value = { "/testupload" }, method = RequestMethod.POST, produces = 
  "application/json")
public @ResponseBody
ResponseEntity<MessageResponseModel> testUpload(
  @RequestParam(value = "filedata", required = false) MultipartFile filedata,
  final HttpServletRequest request) throws IOException {

  InputStream is = null;
  if (filedata == null) {
    is = request.getInputStream();
  }
  else {
    is = filedata.getInputStream();
  }
  byte[] bytes = IOUtils.toByteArray(is);
  System.out.println("read " + bytes.length + " bytes.");

  return new ResponseEntity<MessageResponseModel>(null, null, HttpStatus.OK);
}

使用上面的方法我可以上传一个多部分文件,但是如果我上传一个分块文件,我会从spring获得一个例外:

org.springframework.web.multipart.MultipartException: \
The current request is not …
