@RequestPart cannot mapping string value，Required request part 'hostname' is not present

[RayTigerZ]

ServerCode

@PostMapping("/uploadLog")
 public String uploadAnalysisLog(@RequestPart String hostname, @RequestPart MultipartFile runLog)

ClientCode

MultiValueMap<String, Object> form = new LinkedMultiValueMap<>();
form.add("runLog", fileResource);
form.add("hostname", hostname);
HttpEntity<MultiValueMap<String, Object>> body = new HttpEntity<>(form, headers);
RestTemplate restTemplate = HttpRestClient.getRestTemplateCse();
String result = restTemplate.postForObject(UPLOAD_LOG_URL, body, String.class);

Check developer guide, seems not support this usage: https://servicecomb.apache.org/references/java-chassis/zh_CN/general-development/file-upload.html

But jaxrs @FormParam can be used:

  @Path("/upload2")
  @POST
  @Produces(MediaType.TEXT_PLAIN)
  public String fileUpload2(@FormParam("file1") Part file1, @FormParam("message") String message)
