springcloud学习-06 服务发现Discovery【周阳springcloud2020学习笔记】

对于注册进eureka里面的微服务，可以通过服务发现来获得该服务的信息

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.主启动类添加注解 @EnableDiscoveryClient

3.测试 后台打印结果

***** element:eureka-service
***** element:payment-service
PAYMENT-SERVICE	192.168.163.1	8001	http://192.168.163.1:8001
