public boolean acquire(String lockName) {
    //声明key对象
    String key = LOCK_TITLE + lockName;
    //获取锁对象
    RLock mylock = redissonClient.getLock(key);
    //加锁，并且设置锁过期时间3秒，防止死锁的产生 uuid+threadId
    mylock.lock(3, TimeUnit.SECONDS);
    //加锁成功
    return true;
}
public void release(String lockName) {
    String key = LOCK_TITLE + lockName;
    RLock mylock = redissonClient.getLock(key);
    mylock.unlock();
}

调用如下

        boolean acquire = distributedRedisLock.acquire(CacheKey.REGISTER_SMS_RECALL);
        try {
            if (acquire) {
                taskExecutor.execute(() -> {
                    log.info("多线程测试");
                });
            }
        }catch (Exception e) {
            log.info("{}", ExceptionUtils.getFullStackTrace(e));
        }finally {
            distributedRedisLock.release(CacheKey.REGISTER_SMS_RECALL);
        }

上锁方法如上，但是使用多线程调用的时候，上锁失败了
