feign上传文件报错（已解决） No serializer found for class java.io.FileDescriptor and no

今天用feign上传文件报错，详细报错信息如下

Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class java.io.FileDescriptor and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: org.springframework.web.multipart.support.StandardMultipartHttpServletRequest$StandardMultipartFile["inputStream"]->java.io.FileInputStream["fd"])

解决方案：feign客户端接口上加上

,consumes = MediaType.MULTIPART_FORM_DATA_VALUE

如：

@RequestMapping(value = "/minioFile/uploadFile", method = RequestMethod.POST, produces = "application/json;charset=UTF-8",consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
@ApiOperation(value = "文件上传", notes = "文件上传，form-data,key=multipartFile;")
DataResponse<UploadFileVO> fileUpload(MultipartFile multipartFile);
