java 連接遠程Linux 服務器

創建閉鎖，確保能連接到zk服務器。


// 創建閉鎖
final CountDownLatch countDownLatch = new CountDownLatch(1);

String connectString="139.196.31.237:2181";
int sessionTimeout=5000;
// 創建ZooKeeper對象
ZooKeeper zooKeeper = new ZooKeeper(connectString, sessionTimeout, new Watcher() {
    @Override
    public void process(WatchedEvent watchedEvent) {
        System.out.println("連接zk成功！watchedEvent："+watchedEvent.getState());
        countDownLatch.countDown();
    }
});
// 利用閉鎖的await()方法產生阻塞，等待連接zk的線程執行完畢
countDownLatch.await();
