Redis生成主键ID

使用Redis來生成主鍵ID策略,這裡主要使用 RedisAtomicLong 類來實現主鍵生成策略。具體代碼如下:

/**
     * @Description: 获取自增长值
     * @param key key
     * @return
     */
    public static Long getIncr(String key) {
            RedisAtomicLong redisAtomicLong = new RedisAtomicLong(key,redisTemplate.getConnectionFactory());
                    Long increment = redisAtomicLong.getAndIncrement();
                    redisAtomicLong.expire(0, TimeUnit.SECONDS);
                    return increment;
    }

    /**
     * @Description: 初始化自增长值
     * @param key key
     * @param value 当前值
     */
    public void setIncr(String key, int value) {
            RedisAtomicLong redisAtomicLong = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
                redisAtomicLong.set(value);
                redisAtomicLong.expire(0, TimeUnit.SECONDS);
    }
