redisson实现分布式锁简单使用

依赖

  		<dependency>
            <groupId>org.redisson</groupId>
            <artifactId>redisson-spring-boot-starter</artifactId>
            <version>3.13.1</version>
        </dependency>

使用

 @Autowired
private RedissonClient redissonClient;

 RLock lock = redissonClient.getLock(LockUtil.buildLock(Constant.CREATE_ORDER_LOCK + OrderDTO.getTeNo()));
        //尝试获取锁
        if (lock.tryLock()) {
            try {
              //业务代码；
            } finally {
            //解锁
                lock.unlock();
            }
            }

 RLock lock = redissonClient.getLock(LockUtil.buildLock(Constant.CREATE_ORDER_LOCK + OrderDTO.getTeNo()));
        //一直等待获取锁，知道成功为止。
        lock.Lock(); 
            try {
              //业务代码；
            } finally {
            //解锁
                lock.unlock();
            }
