我目前正在尝试将文件从Angular 4前端上传到Spring Webflux控制器.控制器能够读取@RequestPart值但抛出415 UnsupportedMediaTypeStatusException.
UploadController
@PostMapping( consumes = MediaType.MULTIPART_FORM_DATA_VALUE )
public Mono<Void> save(@RequestPart("file")MultipartFile file) {
log.info("Storing a new file. Recieved by Controller");
this.storageService.store(file);
return Mono.empty();
}
log.info()方法不执行,因此似乎在执行方法之前抛出错误.
错误信息
