java zookeeper 删除目录

要在Java中使用ZooKeeper删除目录，您可以使用ZooKeeper的API方法之一: deleteRecursive。

以下是一个示例代码，演示如何使用ZooKeeper删除目录：

import org.apache.zookeeper.KeeperException;
import org.apache.zookeeper.ZooKeeper;

public class ZookeeperDeleteExample {
    private static final String ZOOKEEPER_HOST = "localhost:2181";
    private static final int SESSION_TIMEOUT = 5000;

    public static void main(String[] args) {
        String path = "/mydir"; // 要删除的目录路径

        try {
            ZooKeeper zooKeeper = new ZooKeeper(ZOOKEEPER_HOST, SESSION_TIMEOUT, null);
            deleteRecursive(zooKeeper, path);
            zooKeeper.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void deleteRecursive(ZooKeeper zooKeeper, String path) throws KeeperException, InterruptedException {
        // 获取指定路径的子节点
        for (String child : zooKeeper.getChildren(path, false)) {
            String childPath = path + "/" + child;
            deleteRecursive(zooKeeper, childPath); // 递归删除子节点
        }

        // 删除当前节点
        zooKeeper.delete(path, -1);
        System.out.println("Deleted path: " + path);
    }
}

请确保您已经将ZooKeeper依赖项添加到项目中。以上代码将连接到本地主机上运行的ZooKeeper服务器，并递归删除指定路径下的所有子节点和当前节点。

请注意，此代码仅用于演示目的，并且没有包含错误处理或异常处理。在实际应用中，您需要根据需要添加适当的错误处理和异常处理。
