我的问题跟你一样。看别人解释导致的原因“一般是由于连接还未完成就执行zookeeper的get/create/exsit操作引起的.”，所以想到了线程休眠

然后我在\src\main\java\com\deem\zkui\controller\Home.java第60行（doGet方法里）增加线程休眠重新编译下就不报错了。
Map<String, Object> templateParam = new HashMap<>(); String zkPath = request.getParameter("zkPath"); String navigate = request.getParameter("navigate"); Thread.sleep(30);// 新增 ZooKeeper zk = ServletUtil.INSTANCE.getZookeeper(request, response, zkServerLst[0], globalProps); List<String> nodeLst; List<LeafBean> leafLst;

该方案仅限参考

from zkui.

我重写了连接成功的事件，就解决了。把这个问题忘记关了
