feign调用文件上传的接口,需要进行相关的配置

@FeignClient(name = “jjt-vend-backend-server”,configuration = FeignMultipartSupportConfig.class)
public interface FileClient {
//调用上传图片接口
/**
* 跨服务调用的方法,注意MultipartFile的注解要用@RequestPart
*/
@RequestMapping(method = RequestMethod.POST, value = “/oss/feign/upload”,
consumes = {MediaType.MULTIPART_FORM_DATA_VALUE},produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
public JsonResponse upload(@RequestPart(“file”) MultipartFile file);

}

@Configuration
public class FeignMultipartSupportConfig {
@Bean
@Primary
@Scope(“prototype”)
public Encoder multipartFormEncoder() {
return new SpringFormEncoder();
}

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

}

注记:
1.接受文件参数要用RequestPart
2.@Configuration注解config类,全局配置,导致该项目其他的feignclient调用传实体类的参数报错,该问题暂时还未解决
