8.zookeeper的curator客户端实现读写锁

上读锁机制：前面全部是读锁或者没锁。
上写锁机制：前面没锁。
读锁示例

@Test
public void readLock() throws Exception {
    InterProcessReadWriteLock lock = new InterProcessReadWriteLock(curatorframework, "/test-node1");
    InterProcessMutex readLock = lock.readLock();
    System.out.println("获取读锁");
    readLock.acquire();
    for (int i = 0; i < 100; i++) {
        Thread.sleep(3000);
        System.out.println(i);
    }
    readLock.release();
}

写锁示例

@Test
public void writeLock() throws Exception {
    InterProcessReadWriteLock lock = new InterProcessReadWriteLock(curatorframework, "/test-node1");
    InterProcessMutex writeLock = lock.writeLock();
    System.out.println("获取写锁");
    writeLock.acquire();
    for (int i = 0; i < 100; i++) {
        Thread.sleep(3000);
        System.out.println(i);
    }
    writeLock.release();
}
