使用

public class test{

    @Autowired
    @Qualifier("redissonClientReport")
    private RedissonClient redissonClient;
    private static final String REDISSON_LOCK_KEY = "redissonLockKey:";

    public void testLock(){

        RLock lock = redissonClient.getLock(REDISSON_LOCK_KEY + id);
        try {
            lock.lock(2, TimeUnit.SECONDS);
            //处理业务
            ………………………………

        }finally {
            lock.unlock();
        }
    }

}
