#端口号

spring:
  application:
    #服务别名——注册到zookeeper注册中心的名称
    name: cloud-provider-payment
  cloud:
    zookeeper:
      connect-string: 101.43.244.40:2181 #linux的ip加暴露的端口号

入口类：

@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain8004 {
    public static void main(String[] args) {
        SpringApplication.run(PaymentMain8004.class,args);
    }
}

controller：

@Slf4j
@RestController
public class PaymentController {
    @Value("${server.port}")        //获取端口号
    private String serverPort;

    @RequestMapping("/payment/zk")
    public String paymentzk(){
        return "springcloud with zookeeper：" + serverPort + "\t" + UUID.randomUUID().toString();
    }
}

启动项目，进入zookeeper容器，查看服务注册：

查看zookeeper注册信息：

RestTemplate的Config：

@Configuration
public class ApplicationContextConfig {
    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

Controller：

INVOKE_URL为远程调用的服务地址，有因为上面provider的服务名称为cloud-provider-payment，所以这里的URL为下面缩写的内容

@RestController
@Slf4j
public class OrderZKController {

    public static final String INVOKE_URL = "http://cloud-provider-payment";

    @Resource
    private RestTemplate restTemplate;

    @RequestMapping("/consumer/payment/zk")
    public String paymentInfo(){
        String result = restTemplate.getForObject(INVOKE_URL + "/payment/zk", String.class);
        return result;
    }

}

启动，测试查看服务注册信息，可以看到Provider和Consumer都被注册到了Zookeeper中：
