The distributed locking usage provided by Curator is simple:

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 lock 2181"). SessionTimeoutMs (5000) .connectionTimeoutMs (10000) .retryPolicy (retryPolicy) .namespace ("text"). Build (); client.start (); InterProcessMutex lock = new InterProcessMutex (client, "/ lock"); try {lock.acquire () System.err.println ("generate order number"); Thread.currentThread (). Sleep (5000L);} catch (Exception e) {} finally {try {lock.release () } catch (Exception e) {e.printStackTrace ();}} try {lock.acquire (); System.err.println ("generate order number") Thread.currentThread () .sleep (Long.MAX_VALUE);} catch (Exception e) {} finally {try {lock.release ();} catch (Exception e) {e.printStackTrace () At this point, I believe you have a better understanding of "how to use the distributed locks provided by Curator".
