@SpringBootApplication@EnableCircuitBreaker@EnableEurekaClient@EnableFeignClients@ComponentScan(excludeFilters = {@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE,value = FeignMultipartSupportConfig.class)})public class BootstrapApplication { public static void main(String[] args) { SpringApplication.run(BootstrapApplication.class, args); }} |
在目标feign上面添加

@FeignClient(name = "micro-picture", fallbackFactory = MicroPictureFactory.class, configuration = FeignMultipartSupportConfig.class)public interface MicroPictureClient {@RequestMapping(value = { "/picture/common/upload/{commonKey}" }, method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE) public String upload(@RequestPart("image") MultipartFile image, @PathVariable("commonKey") Long commonKey); } |
就可以实现对应的服务做图片的上传，针对的图片微服务就可以实现数据的额接收。
对应配置文件的代码

将SpringFormEncoder的默认处理
encoder配置为SpringEncoder

@FeignClient(value = "****", fallbackFactory = UploadClientFallbackFactory.class , configuration = FeignMultipartSupportConfig.class)public interface UploadClient { /** * 上传图片文件 * * @param file * @return */ @PostMapping(value = "/tbk/feedback/upload", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}, consumes = MediaType.MULTIPART_FORM_DATA_VALUE) BaseResponse<String> uploadImage(@RequestPart("file") MultipartFile file);} |
以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
