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); }
