spring-boot Feign

@SpringBootApplication
@EnableEurekaClient
@RestController
@EnableFeignClients  //开启feign
public class DemoApplication {

	@Autowired
	HelloClient client;

	@GetMapping("/hello/{name}")
	public String hello(@PathVariable String name){

		System.out.println(name+" welcome . My is microservice provider user");
		return name+" welcome . I'm microservice provider user";
	}

	@RequestMapping("/say")
	public String hello() {
		return client.hello();
	}

	@FeignClient("provider-user")
	interface HelloClient {
		@GetMapping("/add")
		String hello();
	}

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

@RequestMapping("/add")
public String hello2() {
   return "Hello";
}

Feign接口的请求映射需与注册到eureka的服务的请求地址(/add)一致，方法名可不一致，

当请求/say，则会请求到hello2方法
