在springCloud中使用FeignClient会导致文件流格式错误

在springCloud中使用FeignClient会导致文件流格式错误,只需要把传入的参数加上对应的注解

@FeignClient(value = "dmr-service-con"
        , path = "/con/conBase", ***configuration = MultipartSupportConfig.class***
)
public interface LegalConFeign {
    /**
     * 法务合同附件上传
     */
    @RequestMapping(value = "/legalConUpload", method = RequestMethod.POST, ***consumes = MediaType.MULTIPART_FORM_DATA_VALUE***)
    JsonResponse legalConUpload(@RequestParam("fileSign") String fileSign,
                                @RequestParam("businessName") String businessName,
                                @RequestParam("businessId") String businessId,
                                @RequestParam("applyCode") String applyCode, @RequestPart("file") MultipartFile file);

    /**
     * 法务合同回调
     */
    @RequestMapping(value = "/legalConCallback", method = RequestMethod.POST)
    JsonResponse legalConCallback(@RequestBody JSONObject jsonObject);
}

注意加粗的代码
