基于Redis分布式锁Redisson使用例子

    @Test
    public void testDistributeLock() throws InterruptedException {
        final CountDownLatch cdl = new CountDownLatch(10);
        long time = System.currentTimeMillis();
        RedissonClient redisson = Redisson.create();
        final RLock rLock = redisson.getLock("hello-lock");
        final Map<String, Integer> map = new HashMap<>(1);
        map.put("hello", 0);
        for (int i = 0; i < 10; i++) {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    rLock.lock(10, TimeUnit.SECONDS);
                    map.put("hello", map.get("hello") + 1);
                    rLock.unlock();
                    cdl.countDown();
                }
            }).start();
        }
        cdl.await();
        System.out.println("result ->" + map.get("hello"));
        System.out.println(System.currentTimeMillis() - time);
    }
