Zookeeper注册中心

eureka已经不再更新，代替方案有zookeeper或consoul

zookeeper是一个分布式的协调工具，可以实现服务注册中心

linux 安装zookeeper(https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/)

@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 Payment8004 {

    public static void main(String[] args) {
        SpringApplication.run(Payment8004.class,args);
    }

@RestController
@Slf4j
public class PaymentController {

    @Value("${server.port}")
    private String serverPort;

    @RequestMapping(value = "/payment/zk")
    public String paymentzk() {
        return "springcloud with zookeeper:" + serverPort + "t"

如果不排除自带的3.5.3-zookeeper-beat会报jar包冲突
