使用feign上传图片

1.添加依赖，支持SpringEncodergit

 <dependency>
            <groupId>io.github.openfeign.form</groupId>
            <artifactId>feign-form</artifactId>
            <version>3.4.1</version>
        </dependency>
        <dependency>
            <groupId>io.github.openfeign.form</groupId>
            <artifactId>feign-form-spring</artifactId>
            <version>3.4.1</version>
        </dependency>

2.将SpringFormEncoder的默认处理encoder配置为SpringEncodergithub

@Configuration public class FeignMultipartSupportConfig { @Bean public Encoder multipartFormEncoder(ObjectFactory<HttpMessageConverters> messageConverters) { return new SpringFormEncoder(new SpringEncoder(messageConverters)); } }

3.编写clientspring

@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); }
