使用 spring cloud zookeeper 搭建注册中心，服务注册失败

Question

application.properties:

spring.application.name=zookeeperserver
server.port=8090
spring.cloud.zookeeper.connect-string=zookeeperIp:2181
spring.cloud.zookeeper.discovery.instance-host=localIp
spring.cloud.zookeeper.discovery.instance-port=8090

服务启动成功

但zookeeper中没有相应的节点
