</project>

配置文件application.yml

server:
  port: 8765

spring:
  application:
    name: service-feign

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

接口类SchedualServiceHi.java

@FeignClient(value = "service-hi")
public interface SchedualServiceHi {
    @RequestMapping(value = "/hi",method = RequestMethod.GET)
    String sayHiFromClientOne(@RequestParam(value = "name") String name);
}

 

启动类

@SpringBootApplication
@EnableEurekaClient
@EnableDiscoveryClient
@EnableFeignClients
@RestController
public class ServiceFeignApplication {

    @Autowired
    private SchedualServiceHi schedualServiceHi;

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


    @GetMapping(value = "/hi")
    public String hi(@RequestParam String name) {
        return schedualServiceHi.sayHiFromClientOne( name );
    }

}

二、测试
