zookeeper注册中心
使用zookeeper作为注册中心就不需要像eureka一样，在写一个eureka-server的服务了，因为zookeeper本身就是一个服务端，只需要编写需要进行服务注册的客户端即可

代码解读
复制代码
spring:
application:
name: provide-zookeeper
cloud:
zookeeper:
connect-string: localhost:2181 # zookeeper连接地址
启动该服务后，zookeeper中就可以看到services目录下有了一个provide-zookeeper文件夹，provide-zookeeper就是指的provide-zookeeper服务，下面会有一个个的实例，可以获取到实例的信息

get /services/provide-zookeeper/39a78506-f2cb-4c8f-bbab-768f1f9fc702
{"name":"provide-zookeeper","id":"39a78506-f2cb-4c8f-bbab-768f1f9fc702","address":"192.168.1.124","port":8004,"sslPort":null,"payload":{"@class":"org.springframework.cloud.zookeeper.discovery.ZookeeperInstance","id":"application-1","name":"provide-zookeeper","metadata":{}},"registrationTimeUTC":1630313091916,"serviceType":"DYNAMIC","uriSpec":{"parts":[{"value":"scheme","variable":true},{"value":"://","variable":false},{"value":"address","variable":true},{"value":":","variable":false},{"value":"port","variable":true}]}}
服务节点在zookeeper中注册的是临时节点
可以看到该节点的ephemeralOwner不为0
