#8004表示注册到zookeeper服务器的支付服务提供者端口号
server:
  port: 8004
#服务别名----注册zookeeper到注册中心名称
spring:
  application:
    name: cloud-provider-payment
  cloud:
    zookeeper:
      connect-string: 192.168.111.144:2181  # 您的linux服务器地址  ifconfig查看
 

@SpringBootApplication
@EnableDiscoveryClient //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
public class PaymentMain8004
{
    public static void main(String[] args)
    {
        SpringApplication.run(PaymentMain8004.class,args);
    }

}

@RestController
public class PaymentController
{
    @Value("${server.port}")
    private String serverPort;

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

解决zookeeper版本jar包冲突问题

zk 版本和springcloud的zk版本不一致一般采用排除自带的zk版本 使用自己的zk 修改pom
