我有这样一种方法：

@RequestMapping(method = RequestMethod.POST)
@ResponseStatus(HttpStatus.CREATED)
@ResponseBody
@PreAuthorize("@securityService.isAllowedAccessByCurrentUser(#resource?.userId)")
public Post createPost(@RequestPart(required = false) @Valid final MultipartFile media,
        @RequestPart(required = true) @Valid PostUploadDto resource, final UriComponentsBuilder uriBuilder,
        final HttpServletResponse response) {
    return service.create(resource, media);
}

在application.properties中，我有这个：

# fileupload
spring.servlet.multipart.max-file-size=1024MB
spring.servlet.multipart.max-request-size=1024MB
spring.servlet.multipart.enabled=true

当我尝试上传1.2 MB的文件时，我得到413请求实体太大

我究竟做错了什么？

编辑：

这是调用API的React代码：

export const createNewPost = async (caption, userId, tokenData, imageURI, gameId) => {
  const resource = {
    userId,
    caption,
    hashtags: allTagsFrom(caption),
    mentions: allMentionsFrom(caption),
    gameId,
    createdOn: moment()
      .utc()
      .format('YYYY-MM-DD HH:mm:ss'),
  };
  if (imageURI) {
    const { uri, type } = imageURI;
    const data = [
      {
        name: 'resource',
        type: 'application/json',
        data: JSON.stringify(resource),
      },
      {
        name: 'media',
        type,
        filename: 'media.jpg',
        data: RNFetchBlob.wrap(uri.substring(7)),
      },
    ];
    return RNFetchBlob.fetch(
      'POST',
      `${serverUrl}/post`,
      {
        Authorization: `Bearer ${tokenData.access_token}`,
        'Content-Type': 'multipart/form-data',
        Accept: 'application/json',
      },
      data
    );
  } else {
    return RNFetchBlob.fetch(
      'POST',
      `${serverUrl}/post`,
      {
        Authorization: `Bearer ${tokenData.access_token}`,
        'Content-Type': 'multipart/form-data',
        Accept: 'application/json',
      },
      [
        {
          name: 'resource',
          type: 'application/json',
          data: JSON.stringify(resource),
        },
      ]
    );
  }
};

有趣的是，如果媒体处于某个阈值以下，该阈值小于我在属性文件中设置的阈值，那么我可以成功进行此调用
