如何在Java中实现分布式任务调度和分布式锁

public class DistributedTaskScheduler {

    private static final int NUM_OF_NODES = 3; // 假设有3个节点

    public static void main(String[] args) {
        ScheduledExecutorService executorService = Executors.newScheduledThreadPool(NUM_OF_NODES);

        for (int i = 0; i < NUM_OF_NODES; i++) {
            final int nodeId = i;
            executorService.scheduleWithFixedDelay(() -> {
                // 节点执行具体任务的逻辑
                System.out.println("Node " + nodeId + " is executing task...");
            }, 0, 1, TimeUnit.SECONDS);
        }
    }
}

public class DistributedLock {

    private static final String LOCK_PATH = "/distributed_lock";

    public static void main(String[] args) throws Exception {
        CuratorFramework client = CuratorFrameworkFactory.newClient("localhost:2181", new RetryNTimes(10, 5000));
        client.start();

        InterProcessMutex lock = new InterProcessMutex(client, LOCK_PATH);

        for (int i = 0; i < 3; i++) {
            new Thread(() -> {
                try {
                    lock.acquire();
                    System.out.println(Thread.currentThread().getName() + " acquired the lock.");
                    Thread.sleep(1000);
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    try {
                        lock.release();
                        System.out.println(Thread.currentThread().getName() + " released the lock.");
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }).start();
        }

        Thread.sleep(Integer.MAX_VALUE); // 阻塞主线程，保持锁生效
    }
}
