使用RedisAtomicLong 原子类使用CAS操作来生成ID

@Service
public class RedisSequenceFactory {
    @Autowired
    RedisTemplate<String, String> redisTemplate;

    public void setSeq(String key, int value, Date expireTime) {
        RedisAtomicLong counter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
        counter.set(value).expireAt(expireTime);
    }

    public void setSeq(String key, int value, long timeout, TimeUnit unit) {
        RedisAtomicLong counter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
        counter.set(value).expire(timeout, unit);
    }

    public long generate(String key) {
        RedisAtomicLong counter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
        return counter.incrementAndGet();
    }

    public long incr(String key, Date expireTime) {
        RedisAtomicLong counter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
        counter.expireAt(expireTime);
        return counter.incrementAndGet();
    }

    public long incr(String key, int increment) {
        RedisAtomicLong counter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
        return counter.addAndGet(increment);
    }

    public long incr(String key, int increment, Date expireTime) {
        RedisAtomicLong counter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
        counter.expireAt(expireTime);
        return counter.addAndGet(increment);
    }
}
