zookpeer链接报错Socket is not connected

本文介绍: 再zookeeper 回调 event的时候收不到，当打开 debug的时候爆。JDK版本选的15 zk 当前版本不支持。1 查看 zk 是否启动成功。2 查看端口以及防火墙。

Object waiter = new Object();

        ZooKeeper zkClient;
        try
        {
            synchronized (waiter) {
                final CountDownLatch connectedSignal = new CountDownLatch(1);
                zkClient = new ZooKeeper("zk地址"
                        , 1000, event -&gt; {
                    if (event.getState() == Watcher.Event.KeeperState.SyncConnected) {
                        connectedSignal.countDown();
                        System.out.println( "Hello end!" );
                    }
                });
                connectedSignal.await();
            }
        }
        catch(Exception g)
        {
            g.printStackTrace();
        }
