The troubleshooting process.
The Internet has said firewall (tried not to); some say zk version (this side or third-party package indirectly dependent, and there are package conflicts, tried to remove a did not work);

Solution:
Modified the timeout time

ZookeeperConfiguration zookeeperConfiguration = new ZookeeperConfiguration(serverList, namespace);
zookeeperConfiguration.setSessionTimeoutMilliseconds(600000);
zookeeperConfiguration.setConnectionTimeoutMilliseconds(600000);
zookeeperConfiguration.setMaxSleepTimeMilliseconds(30000);
zookeeperConfiguration.setBaseSleepTimeMilliseconds(10000);
ZookeeperRegistryCenter regCenter = new ZookeeperRegistryCenter(zookeeperConfiguration);

Local boot OK
