java.lang.IllegalMonitorStateException: attempt to unlock lock, not locked by current thread by node id: 59f44274-17cb-40cd-b83b-08ed1ed3ffc7 thread-id: 70
当前线程没有被锁，但是企图去释放锁。
解决办法
判断是否已锁，且锁是否被当前线程持有
/*** 释放锁* 判断要解锁的key是否已被锁定;判断要解锁的key是否被当前线程持有*/if (lock.isLocked() && lock.isHeldByCurrentThread()) {log.info("线程:" + Thread.currentThread().getName() + "准备释放锁");lock.unlock();}
加锁解锁参考代码
参考代码
@ResourceRedissonClient redissonClient;private int ticket = 100;private final static String LOCK_KEY = "TICKET_KEY";@Overridepublic void hello(String name) {//定义锁RLock lock = redissonClient.getLock(LOCK_KEY);try {//尝试加锁,最大等待时间2秒(如果还没等到锁，则失败)，最大持锁时间10秒(防止意外情况无法释放)if (lock.tryLock(2000, 10000, TimeUnit.MILLISECONDS)) {int t = new Random().nextInt(4000);log.info("线程:" + Thread.currentThread().getName() + "获得了锁,占锁时间:" + t + " 毫秒");Thread.sleep(t);log.info("剩余数量:{}", --ticket);} else {log.info("线程:" + Thread.currentThread().getName() + "未获取到锁");}} catch (Exception e) {log.error("程序执行异常:{}", e);} finally {/*** 释放锁* 判断要解锁的key是否已被锁定;判断要解锁的key是否被当前线程持有*/if (lock.isLocked() && lock.isHeldByCurrentThread()) {log.info("线程:" + Thread.currentThread().getName() + "准备释放锁");lock.unlock();}}}
