在zk根目录下有a，zookeeper两个节点，在a下有孩子a1.

1. [zk: s201:2181(CONNECTED) 9] ls /
2. [a, zookeeper]
3. [zk: s201:2181(CONNECTED) 10] ls /a
4. [a1]

递归代码如下：

1. @Test
2. public void TestZKAll() throws Exception {
3. ls(“/”);
4. }
6. /**
7. * 列出指定path下所有孩子
8. */
9. public void ls(String path) throws Exception {
10. System.out.println(path);
11. ZooKeeper zk = new ZooKeeper(“192.168.xxx.xxx:2181”,5000,null);
12. List<String> list = zk.getChildren(path,null);
13. //判断是否有子节点
14. if(list.isEmpty() || list == null){
15. return;
16. }
17. for(String s : list){
18. //判断是否为根目录
19. if(path.equals(“/”)){
20. ls(path + s);
21. }else {
22. ls(path +“/” + s);
23. }
24. }
25. }

输出结果：

1. /a
2. /a/a1
3. /zookeeper
4. /zookeeper/quota
