使用feign上传图片

1.添加依赖，支持SpringEncoder

        <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SpringEncoder

@Configuration
public class FeignMultipartSupportConfig {

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

3.编写client

@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);
}
