在zk根目錄下有a，zookeeper兩個節點，在a下有孩子a1.

[zk: s201:2181(CONNECTED) 9] ls /
[a, zookeeper]
[zk: s201:2181(CONNECTED) 10] ls /a
[a1]

遞迴程式碼如下：

    @Test
    public void TestZKAll() throws Exception {
        ls("/");
    }

    /**
     * 列出指定path下所有孩子
     */
    public void ls(String path) throws Exception {
        System.out.println(path);
        ZooKeeper zk = new ZooKeeper("192.168.xxx.xxx:2181",5000,null);
        List<String> list = zk.getChildren(path,null);
        //判斷是否有子節點
        if(list.isEmpty() || list == null){
            return;
        }
        for(String s : list){
            //判斷是否為根目錄
            if(path.equals("/")){
                ls(path + s);
            }else {
                ls(path +"/" + s);
            }
        }
    }
 

輸出結果：

/a
/a/a1
/zookeeper
/zookeeper/quota
