获取节点的子节点

public class ZooKeeper_GetChildren_API_Sync_Usage implements Watcher {                private static CountDownLatch connectedSemaphore = new CountDownLatch(1);        private static ZooKeeper zk = null;                public static void main (String[] args) throws Exception{                                String path = "/huangyi";                zk = new ZooKeeper("202.201.13.55:2100",                                5000,                                new ZooKeeper_GetChildren_API_Sync_Usage());                       connectedSemaphore.await();                                zk.create(path, "".getBytes(),                                Ids.OPEN_ACL_UNSAFE, CreateMode.PERSISTENT);                zk.create(path+"/c1", "".getBytes(),                                Ids.OPEN_ACL_UNSAFE, CreateMode.EPHEMERAL);                                List childrenList = zk.getChildren(path, true);                System.out.println(childrenList);                        zk.create(path+"/c2", "".getBytes(),                                Ids.OPEN_ACL_UNSAFE, CreateMode.EPHEMERAL);                                Thread.sleep( Integer.MAX_VALUE);        }                public void process(WatchedEvent event) {                if (KeeperState.SyncConnected == event.getState()) {                        if (EventType.None == event.getType() && null == event.getPath()) {                                connectedSemaphore.countDown();                        } else if (event.getType() == EventType.NodeChildrenChanged) {                                try {                                        System.out.println("ReGet Child:" + zk.getChildren(event.getPath(), true));                                               } catch (Exception e) {}                        }                }        }}

结果打印

[c1]ReGet Child:[c1, c2]
