使用RLock加锁时发生错误信息
报错信息：
java.lang.IllegalMonitorStateException: attempt to unlock lock, not locked by current thread by node id: b1834c06-be7d-4946-bddc-e7a34333asb2 thread-id: 78

问题代码复现

如下代码：

public String  gettestRedis() throws InterruptedException {
    log.info("开始取锁 ...");
    String key = "lock:stock:10";
    RLock goodlock = redissonClient.getLock(key);
    // 最大执行时间10秒 最大尝试获取锁时间2秒
    boolean lockAcquired =goodlock.tryLock(10, 2, TimeUnit.SECONDS);
    if (lockAcquired) {
        try {
            log.info("获取锁成功");
            log.info("执行任务");
            Thread.sleep(10000);
            log.info("任务执行完毕");
        } finally {
            goodlock.unlock();
        }
    } else {
        log.info("获取锁失败");
    }
    return  "null";
}

原因：

在执行任务后执行Thread.sleep(10000);代码，进入睡眠，等10秒过后，当前线程不是刚才的线程，释放锁失败

改正：

使用isHeldByCurrentThread判断当前线程是否持有指定锁。改正代码如下

    public String gettestRedis() throws InterruptedException {
        log.info("开始取锁 ...");
        String key = "lock:stock:10";
        RLock goodlock = redissonClient.getLock(key);
        // 最大执行时间10秒 最大尝试获取锁时间2秒
        boolean lockAcquired =goodlock.tryLock(10, 2, TimeUnit.SECONDS);
        if (lockAcquired) {
            try {
                log.info("获取锁成功");
                log.info("执行任务");
                Thread.sleep(10000);
                log.info("任务执行完毕");
            } finally {
                if (lockAcquired && goodlock.isHeldByCurrentThread()) {
                    goodlock.unlock();
                    log.info("锁已释放");
                }
            }
        } else {
            log.info("获取锁失败");
        }
        return "null";
    }

执行结果：
