追踪微服务脉络：Eureka中实现分布式链路追踪的精妙之道

@Autowired
private EurekaClient eurekaClient;

public void logServiceRegistry() {
    // 获取所有的服务实例
    Applications applications = eurekaClient.getApplications();
    for (Application application : applications.getRegisteredApplications()) {
        String serviceName = application.getName();
        for (InstanceInfo instanceInfo : application.getInstances()) {
            // 获取服务实例的信息
            String instanceId = instanceInfo.getId();
            String hostName = instanceInfo.getHostName();
            int port = instanceInfo.getPort();
            // 打印服务名称，实例ID，主机名和端口
            log.info("Service: {}, InstanceId: {}, Host: {}, Port: {}", serviceName, instanceId, hostName, port);
        }
    }
}
