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
