给一个单体项目加装Feign

1.导入pom坐标

<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId><version>4.1.2</version>
</dependency>

2.主函数注解

@EnableFeignClients
public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}}

3.yml配置

  cloud:openfeign:okhttp:enabled: true

4.编写Feign客户端

@FeignClient("file")
public interface FileClient {@DeleteMapping("/test")Result deleteTestFile(@RequestParam("test_file") String test_file);}

5.使用

@Autowired
private FileClient fileClient;
