1.3 Eureka Client Matadata - fanpan26/Fly.SpringCloud GitHub Wiki

在Eureka Client中新建RestController，注入o.s.cloud.client.discovery.DiscoveryClient,通过调用getInstances(serviceId) 返回matadata信息

---

@RestController
@RequestMapping("/api")
public class UserServiceController {

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

    @Autowired
    private DiscoveryClient discoveryClient;

    /**
     * 获取用户服务的详细信息
     * */
    @GetMapping("/user-service")
    public List<ServiceInstance> userServiceInfo(){
       return this.discoveryClient.getInstances(serviceId);
    }
}

修改application.yml,增加matadata

instance:
    prefer-ip-address: true
    metadata-map:
      # 这里自定义，些什么都可以 key/value
      description: 用户微服务：包含用户基础信息接口，账户接口等

运行程序，访问：http://localhost:8081/api/user-service
