服务端的代码
   @Autowired
    private ossFileService oss;

    @RequestMapping("/upimagefile")
    public void upimagefile(@RequestPart MultipartFile file) {
        String upfile = oss.upfile(file);
        if(StringUtils.equals(upfile,"error")){
            System.out.println("上传图片失败");
        }
        else {
            System.out.println("成功上传图片");
        }

    }

客户端的代码
@FeignClient(value = "ALIYUNFILE",configuration=aliyunFileFeign.Myconfig.class )
public interface aliyunFileFeign {
@Headers("Content-Type:multipart/form-data")
@RequestMapping(value = "/upimagefile", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
public void upimagefile(@RequestPart MultipartFile file);

@Configuration
public class Myconfig{
    @Autowired
    private ObjectFactory<HttpMessageConverters> messageConverters;

    @Scope("prototype")
    @Primary
    @Bean
    public Encoder feignFormecoder(){
        return new SpringFormEncoder(new SpringEncoder(messageConverters));
    }

    @Bean
    public feign.Logger.Level multipartLoggerLevel(){
        return Logger.Level.FULL;
    }
}

}

springboot为2.1.9  
这是jackson的依赖版本
                <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.9.10</version>
                        </dependency>

在@RequestMapping注解中添加 consumes = MediaType.MULTIPART_FORM_DATA_VALUE配置项即可解决
如：
@RequestMapping(value = "/uploadFile",method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
