zookeeper数据迁移

在不停机的情况下，实现集群之间数据迁移代码：

 private void create(ZooKeeper zk1, ZooKeeper zk2, String path) throws Exception {

         List<String> list = zk1.getChildren(path, null);

         for (String str : list) {

             if (path.endsWith("/")) {

             } else {

                 path = path + "/";

             }

             System.out.println(path + str);

             zk2.create("/wapage_back" + path + str, zk1.getData(path+str, false, null), Ids.OPEN_ACL_UNSAFE, CreateMode.PERSISTENT);

             create(zk1, zk2, path + str);

         }

         if (!path.endsWith("/")) zk2.setData("/wapage_back" + path, zk1.getData(path, false, null), -1);

     }
