示例

操作失败重试机制：1000毫秒间隔，重试3次

RetryPolicy policy = new ExponentialBackoffRetry(1000, 3);

创建Curator客户端

CuratorFramework client = CuratorFrameworkFactory.newClient("192.168.29.110:2181", policy);

启动

client.start();

创建锁对象

final InterProcessMutex lock = new InterProcessMutex(client, "/mylock");

请求锁

lock.acquire();

释放锁

lock.release();
