測試開發環境

package com.demo;

import java.io.IOException;

import org.apache.zookeeper.CreateMode;
import org.apache.zookeeper.KeeperException;
import org.apache.zookeeper.WatchedEvent;
import org.apache.zookeeper.Watcher;
import org.apache.zookeeper.ZooDefs;
import org.apache.zookeeper.ZooKeeper;
import org.apache.zookeeper.data.Stat;

public class ZooKeeperTest {

	public static void main(String[] args) throws IOException, KeeperException, InterruptedException {
		ZooKeeper zk = new ZooKeeper("127.0.0.1:2181", 30000, new TestWatcher());
//		String node = "/zookeeper/quota";
		String node = "/demo";
		Stat stat = zk.exists(node, false);
		
		if(null==stat) {
			//創建節點
			String createResult = zk.create(node, "test".getBytes(), ZooDefs.Ids.CREATOR_ALL_ACL, CreateMode.PERSISTENT);
			System.out.println(createResult);
		}
		byte[] data = zk.getData(node, false, stat);
		System.out.println(new String(data));
		zk.close();
		
	}
	
}

class TestWatcher implements Watcher{

	@Override
	public void process(WatchedEvent event) {
		// TODO Auto-generated method stub
		System.out.println("*****************************");
		System.out.println("path:  " + event.getPath());
		System.out.println("type:  " + event.getType());
		System.out.println("state:  " + event.getState());
		System.out.println("*****************************");
