1 Create a Demo Class and run
import ption;
import Exception;
import dEvent;
import r;
import ype;
import per;
public class ZoomkeepTest2 {
// 创建一个与服务器的连接
ZooKeeper zk = null;
public ZoomkeepTest2() {
try {
zk = new ZooKeeper("127.0.0.1:2181", 500000, new WatcherImpl());
// a("/zk-demo/watch-this", true, null);
while (true) {
}
} catch (IOException e) {
tackTrace();
} finally {
// 关闭连接
if (null != zk) {
try {
();
} catch (InterruptedException e) {
tackTrace();
}
}
}
}
public class WatcherImpl implements Watcher {
public void process(WatchedEvent event) {
System.
out
.println("已经触发了" + e() + "事件！");
if (e().equals(EventType.
NodeDataChanged
)) {
try {
System.
out
.println(new
String(a("/zk-demo/watch-this", false, null)));
} catch (KeeperException e) {
tackTrace();
} catch (InterruptedException e) {
tackTrace();
}
}
er(new WatcherImpl());
try {
a("/zk-demo/watch-this", true, null);
} catch (KeeperException e) {
tackTrace();
} catch (InterruptedException e) {
tackTrace();
}
}
}
public static void main(String[] args) throws IOException, KeeperException,
InterruptedException {
ZoomkeepTest2 zt = new ZoomkeepTest2();
}
}
2 Run “” and set node date:
set /zk-demo/watch-this data3333dsafsa
set /zk-demo/watch-this data3333dsafsa12
3 The Console will output:
已经触发了NodeDataChanged事件！
data3333dsafsa
已经触发了NodeDataChanged事件！
data3333dsafsa12
