Curator是一个Apache开源的ZooKeeper客户端库，它提供了许多高级特性和工具类，用于简化在分布式环境中使用ZooKeeper的开发。其中之一就是可重入锁。

Curator提供了InterProcessMutex类来实现可重入锁。以下是使用Curator实现ZooKeeper可重入锁的示例：

import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.framework.recipes.locks.InterProcessMutex;
import org.apache.curator.framework.recipes.locks.InterProcessSemaphoreMutex;
import org.apache.curator.retry.ExponentialBackoffRetry;

public class ZooKeeperReentrantLockExample {
private static final String ZK_CONNECTION_STRING = "localhost:2181";
private static final String LOCK_PATH = "/my-lock";

public static void main(String[] args) throws Exception {
CuratorFramework client = CuratorFrameworkFactory.newClient(
ZK_CONNECTION_STRING, new ExponentialBackoffRetry(1000, 3));
client.start();

InterProcessMutex lock = new InterProcessMutex(client, LOCK_PATH);

try {
if (lock.acquire(10, TimeUnit.SECONDS)) {
// 获得锁后执行逻辑
System.out.println("Lock acquired. Performing the critical section.");

// 模拟处理时间
Thread.sleep(5000);

System.out.println("Critical section completed.");
} else {
System.out.println("Failed to acquire the lock.");
}
} finally {
lock.release();
client.close();
}
}
}
