zookeeper递归输出所有节点

在zk根目录下有a，zookeeper两个节点，在a下有孩子a1.

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

递归代码如下：

    @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 list = zk.getChildren(path,null);
        //判断是否有子节点
        if(list.isEmpty() || list == null){
            return;
        }
        for(String s : list){
            //判断是否为根目录
            if(path.equals("/")){
                ls(path + s);
            }else {
                ls(path +"/" + s);
            }
        }
    }

输出结果：

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