我想上传像article这样的多部分文件。

@RequestMapping(consumes = MediaType.MULTIPART_FORM_DATA_VALUE, method = {RequestMethod.POST, RequestMethod.PUT})
public Mono<ResponseEntity<UploadResult>> multipartUploadHandler(@RequestHeader HttpHeaders headers, @RequestBody Flux<Part> parts) {
    return parts
            .ofType(FilePart.class) // We'll ignore other data for now
            .flatMap((part) -> saveFile(headers, s3config.getBucket(), part))
            .collect(Collectors.toList())
            .map((keys) -> ResponseEntity.status(HttpStatus.CREATED)
                    .body(new UploadResult(HttpStatus.CREATED, keys)));
}

但是当我发送请求时，我得到415

有什么问题吗？
