springcloud學習-06 服務發現Discovery【周陽springcloud2020學習筆記】

對於註冊進eureka裏面的微服務，可以通過服務發現來獲得該服務的信息

1.修改8001 controller

   	@Autowired
   	private DiscoveryClient discoveryClient;

   	@Value("${spring.application.name}")
   	private String appName;

   	@GetMapping(value = "/discovery")
   	public Object discovery(){
   		List<String> services = discoveryClient.getServices();
   		for (String element : services) {
   			log.info("***** element:"+element);
   		}
   		List<ServiceInstance> instances = discoveryClient.getInstances(appName);
   		for (ServiceInstance instance : instances) {
   			log.info(instance.getServiceId()+"\t"+instance.getHost()+"\t"+instance.getPort()+"\t"+instance.getUri());
   		}
   		return this.discoveryClient;
   	}

2.主啓動類添加註解 @EnableDiscoveryClient

3.測試 後臺打印結果
