锁
锁
Redisson 的分布式锁允许跨应用程序/服务器进行线程同步。Redisson 的锁和同步器列表包括：
- Lock
- FairLock
- MultiLock
- ReadWriteLock
- Semaphore
- PermitExpirableSemaphore
- CountDownLatch
参与《DistributedSystem-Notes》中有关于分布式锁的详细讨论。
Lock，非公平锁
RLock lock = client.getLock("lock");
lock.lock();
// perform some long operations...
lock.unlock();
MultiLock
Redisson 的 RedissonMultiLock 组合了多个 RLock 对象，并将它们视为一个锁：
RLock lock1 = clientInstance1.getLock("lock1");
RLock lock2 = clientInstance2.getLock("lock2");
RLock lock3 = clientInstance3.getLock("lock3");
RedissonMultiLock lock = new RedissonMultiLock(lock1, lock2, lock3);
lock.lock();
// perform long running operation...
lock.unlock();
