controller

@RestController
public class ControllerTest {

    @Autowired
    TestClient testClient;


    @RequestMapping("feign/h1")
    public String hello1(){
        System.out.println("hello1来了");
        testClient.hh();
        return "TestController hello1";
    }

    @RequestMapping("feign/h2")
    public String hello2(){
        System.out.println("hello2来了");
        return "TestController hello2";
    }

    @RequestMapping("feign/h3")
    public String hello3(){
        System.out.println("hello3来了");
        return "TestController hello3";
    }
}

client

@FeignClient(name = "testClient",url = "localhost:8080")
public interface TestClient {
    @RequestMapping("feign/h2")
    String hh();

}

  

main

@SpringBootApplication
@EnableFeignClients
public class MainApplication {
    public static void main(String[] args) {
        SpringApplication.run(MainApplication.class,args);
    }
}
测试 直接浏览器输入:localhost:8080/fegin/h1
访问controller,然后controller来回转,没什么意义就是简单演示一下
