 获取连接

    	
    	CuratorFramework client = CuratorFrameworkFactory.builder()
                .connectString("127.0.0.1:2181")
                .sessionTimeoutMs(5000)
                .connectionTimeoutMs(3000)
                .retryPolicy(new ExponentialBackoffRetry(1000, 3))
                .build();

　　

 

InterProcessMutex的使用

获取进程锁

    	CuratorFramework client = CuratorFrameworkFactory.builder()
                .connectString("127.0.0.1:2181")
                .sessionTimeoutMs(5000)
                .connectionTimeoutMs(3000)
                .retryPolicy(new ExponentialBackoffRetry(1000, 3))
                .build();
    	client.start();
    	
    	String lockName = "/head";  
    	InterProcessLock lock1 = new InterProcessMutex(client, lockName);  
    	InterProcessLock lock2 = new InterProcessMutex(client, lockName);  
    	lock1.acquire();  
    	boolean result = lock2.acquire(1, TimeUnit.SECONDS);  
    	System.out.println(result);
    	lock1.release();  
    	result = lock2.acquire(1, TimeUnit.SECONDS);  
    	System.out.println(result);
    	client.close();
