Curator 提供的分布式锁用法，很简单：

package curator.lock;import org.apache.curator.RetryPolicy;import org.apache.curator.framework.CuratorFramework;import org.apache.curator.framework.CuratorFrameworkFactory;import org.apache.curator.framework.recipes.locks.InterProcessMutex;import org.apache.curator.retry.ExponentialBackoffRetry;public class InterProcessMutexDemo {        public static void main(String[] args) {                RetryPolicy retryPolicy = new ExponentialBackoffRetry(1000, 3);                final CuratorFramework client = CuratorFrameworkFactory.builder().connectString("127.0.0.1:2181").sessionTimeoutMs(5000).connectionTimeoutMs(10000).retryPolicy(retryPolicy).namespace("text").build();                client.start();                                InterProcessMutex lock = new InterProcessMutex(client,"/lock");                try {                        lock.acquire();                        System.err.println("生成订单号");                        Thread.currentThread().sleep(5000L);                } catch (Exception e) {                } finally {                        try {                                lock.release();                        } catch (Exception e) {                                e.printStackTrace();                        }                }                                try {                        lock.acquire();                        System.err.println("生成订单号");                        Thread.currentThread().sleep(Long.MAX_VALUE);                } catch (Exception e) {                } finally {                        try {                                lock.release();                        } catch (Exception e) {                                e.printStackTrace();                        }                }                       }}
