springboot redis 用RedisTemplate執行lua腳本報錯：@user_script:1: ERR value is not an integer or out of range

代碼如下：

/**
 * 獲取分布式鎖
 *
 * @param lockKey     鎖
 * @param requestId   請求標識
 * @param expireTime  單位秒|你認為此方法需要多少時間，設置一個最長時間，此時間必須大於需要調用鎖的業務方法邏輯的最大時間，否則鎖會沖突
 * @param waitTimeout 單位毫秒|如果拿不到鎖，那么休眠，然后反反復復重試，直到拿到鎖為止
 *                    demo redisService.getLock("lock", uuid, 10, 1500) 調用方法的業務邏輯最多需要1秒執行完成，1500毫秒一直等待（默認休眠500毫秒一次輪回）線程不執行，等到1500毫秒到了，才執行完整個方法
 * @return 是否獲取成功
 */
public boolean getLock(String lockKey, String requestId, long expireTime, long waitTimeout) {
    // 當前時間
    long nanoTime = System.nanoTime();
    try {
        String script = "if redis.call('setnx',KEYS[1],ARGV[1]) == 1 then  return redis.call('expire',KEYS[1],ARGV[2])  else return 0 end";
        logger.debug("開始獲取分布式鎖-key[{}]", lockKey);
        int count = 0;
        List<String> lockKeyList = Collections.singletonList(lockKey);
        do {
            RedisScript<Long> redisScript = new DefaultRedisScript<>(script, Long.class);
            logger.debug("嘗試獲取分布式鎖-key[{}]requestId[{}]count[{}]", lockKey, requestId, count);

            Object result = redisTemplate.execute(redisScript, lockKeyList, requestId, expireTime + "");
            Long SUCCESS = 1L;
            if (SUCCESS.equals(result)) {
                logger.debug("嘗試獲取分布式鎖-key[{}]成功", lockKey);
                return true;
            }
            //休眠200毫秒
            Thread.sleep(200L);
            count++;
        } while ((System.nanoTime() - nanoTime) < TimeUnit.MILLISECONDS.toNanos(waitTimeout));
    } catch (Exception e) {
        e.printStackTrace();
        logger.error("嘗試獲取分布式鎖-key[{}]異常", lockKey);
        logger.error(e.getMessage(), e);
    }
    return false;
}

/**
 * 釋放鎖
 *
 * @param lockKey 鎖
 * @param value   請求標識
 * @return 是否釋放成功
 */
public boolean releaseLock(String lockKey, String value) {
    String script = "if redis.call('get',KEYS[1]) == ARGV[1] then return redis.call('del',KEYS[1]) else return 0 end";
    DefaultRedisScript<Long> redisScript = new DefaultRedisScript<>(script, Long.class);
    Object result = redisTemplate.execute(redisScript, Collections.singletonList(lockKey), value);
    Long SUCCESS = 1L;
    if (SUCCESS.equals(result)) {
        logger.debug("釋放鎖成功key[{}]value[{}]", lockKey, value);
        return true;
    }
    return false;
}

 

錯誤如下：

分析，可能是值的類型不對或長度太長了?

1、修改value 的長度以后錯誤仍然存在。

2、在分析是不是返回值的類型不對，改為Integer后，又拋出另一個錯誤

3、改為String類型以后錯誤仍然存在。

最后百度可能是值序列化的問題，

4、修改RedisConfig

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
    redisTemplate.setConnectionFactory(factory);
    return redisTemplate;
}
改為：

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
    redisTemplate.setConnectionFactory(factory);

　　RedisSerializer stringRedisSerializer = new StringRedisSerializer();
　　redisTemplate.setKeySerializer(stringRedisSerializer);
   redisTemplate.setValueSerializer(stringRedisSerializer);
   redisTemplate.setHashKeySerializer(stringRedisSerializer);
   redisTemplate.setHashValueSerializer(stringRedisSerializer);

    return redisTemplate;
}

  嘿嘿，果然可以了，就是redis 值序列化的問題， 默認的是JdkRedisSeerializer，改為StringRedisSerializer 就好了
