解决方法

FeignClient

设置consumesmultipart/form-data

注意:MultipartFile需标注为@RequestPart,而不是@RequestParam

@FeignClient(name = "file-upload", url = "${file-upload.url}")
public interface FileUploadFeignClient {

    @PostMapping(value = "/file/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    UploadResponse fileUpload(@RequestPart("file") MultipartFile file);

}

Controller

@RequestMapping("/file")
@RestController
public class FileUploadController {

    @PostMapping(value = "/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    public UploadResponse upload(@RequestPart("file") MultipartFile file) {
        // logic
        return UploadResponse.builder().build();
    }

}
