请问如何观看znodes的子节点？

Question

我使用策展人为Zookeeper.I编程，我想看一下zonde.My代码的子节点如下：

CuratorFramework frameWork = CuratorFrameworkFactory.builder()
            .retryPolicy(new RetryNTimes(3, 1000))
            .connectString("127.0.0.1:2181").build();
frameWork.start();

CuratorWatcher watcher = new CuratorWatcher () {

            @Override
            public void process(WatchedEvent event) throws Exception {
                System.out.println("event :" + event);
            }
            
        };
frameWork.getChildren().usingWatcher(watcher).forPath("/aa"); 
frameWork.setData().forPath("/aa/dd", "asdfd".getBytes());

当调用"/aa/dd“的集合数据时，我希望观察者是triggered.But失败的，请有人知道吗？

馆长有一个菜谱可以做到这一点。请参阅TreeCache：http://curator.apache.org/curator-recipes/tree-cache.html
