spring boot整合redisTemplate获取自增主键incr

@Autowired
    RedisTemplate redisTemplate;

    public Long incr(String key, long liveTime) {
        RedisAtomicLong entityIdCounter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
        Long increment = entityIdCounter.getAndIncrement();

        if ((null == increment || increment.longValue() == 0) && liveTime > 0) {//初始设置过期时间
            entityIdCounter.expire(liveTime, TimeUnit.SECONDS);
        }

        return increment;
    }
