web端保存数据到zookeeper有问题，一直卡在那里

public class ZooKeeperConnection {

private Logger logger = LoggerFactory.getLogger(this.getClass().getName());

private ZooKeeper zooKeeper;

private int sessionTimeout = 50000;

private final CountDownLatch connectedSignal = new CountDownLatch(1);

**public ZooKeeper connect(String host) throws IOException, InterruptedException {
    **zooKeeper = new ZooKeeper(host, sessionTimeout, new Watcher() {
        @Override
        public void process(WatchedEvent watchedEvent) {
           if(watchedEvent.getState() == Event.KeeperState.SyncConnected) {
               connectedSignal.countDown();
           }
        }
    });
    connectedSignal.await();
    return zooKeeper;**
}**

public void close() {
    try {
        zooKeeper.close();
    } catch (InterruptedException e) {
        logger.error("zookeeper connection close fail!", e);
    }
}

}

Start at the ZooKeeperConnection.connect entry point shown in the issue, especially the connectedSignal.await() call and the SyncConnected watcher. Reproduce the web save hang and determine why connection establishment does not complete; the issue does not specify a test, file path, or expected fix, so completion criteria are not defined.
