或者是直接用 spring-cloud-starter-openfeign。

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
服务提供者
MultipartFile 使用 @RequestPart 修饰。
还需要添加一个消费者类型：consumes = MediaType.MULTIPART_FORM_DATA_VALUE
@RestController
@RequestMapping("/xx")
public class FileController {
    @PostMapping(value = "/uploadFile", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    public Response uploadFile(@RequestPart("file") MultipartFile multipartFile, @RequestParam("name") String name) {
        //....
配置Feign的Encoder
@Configuration
public class FeignMultipartConfig {
    @Autowired
    private ObjectFactory<HttpMessageConverters> messageConverters;
    @Bean
    @Primary
    @Scope("prototype")
    public Encoder feignEncoder() {
        return new SpringFormEncoder(new SpringEncoder(messageConverters));
FeignClient
FeignClient 指定 configuration = FeignMultipartConfig.class
consumes = MediaType.MULTIPART_FORM_DATA_VALUE
如下所示。
@FeignClient(name = "xx",configuration = FeignMultipartConfig.class)
@RequestMapping("/xx")
public interface FeignService {
    @PostMapping(value = "/uploadFile", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    Response uploadFile(@RequestPart("file") MultipartFile multipartFile, @RequestParam("name") String name);
服务消费者
MultipartFile用 @RequestPart 修饰即可。
@RestController
@Slf4j
public class FeignController {
    @Autowired
    private FeignService feignService;
    @RequestMapping(value = "/uploadFile")
    public String fileUpload(@RequestPart("file") MultipartFile file, @RequestParam("name") String name ) {
        log.info("文件上传---fileName---{}",file.getOriginalFilename());
        return feignService.uploadFile(file,name);
