springboot redis 用RedisTemplate执行lua脚本报错：@user_script:1: ERR value is not an integer or out of range

标签：$0   template   rip   handler   efault   ISE   range   nan   json   

代码如下：

/**

 * @param expireTime  单位秒|你认为此方法需要多少时间，设置一个最长时间，此时间必须大于需要调用锁的业务方法逻辑的最大时间，否则锁会冲突

public boolean getLock(String lockKey, String requestId, long expireTime, long waitTimeout) {
    // 当前时间
    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("开始获取分布式锁-key[{}]", lockKey);
        int count = 0;
        List lockKeyList = Collections.singletonList(lockKey);
        do {
            RedisScript redisScript = new DefaultRedisScript(script, Long.class);
            logger.debug("尝试获取分布式锁-key[{}]requestId[{}]count[{}]", lockKey, requestId, count);

            Object result = redisTemplate.execute(redisScript, lockKeyList, requestId, expireTime + "");
            Long SUCCESS = 1L;
            if (SUCCESS.equals(result)) {
                logger.debug("尝试获取分布式锁-key[{}]成功", lockKey);
                return true;
            }
            //休眠200毫秒
            Thread.sleep(200L);
            count++;
        } while ((System.nanoTime() - nanoTime)     } catch (Exception e) {
        e.printStackTrace();
        logger.error("尝试获取分布式锁-key[{}]异常", lockKey);
        logger.error(e.getMessage(), e);
    }
    return false;
}

/**
 * 释放锁
 *
 * @param lockKey 锁
 * @param value   请求标识
 * @return 是否释放成功
 */
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 redisScript = new DefaultRedisScript(script, Long.class);
    Object result = redisTemplate.execute(redisScript, Collections.singletonList(lockKey), value);
    Long SUCCESS = 1L;
    if (SUCCESS.equals(result)) {
        logger.debug("释放锁成功key[{}]value[{}]", lockKey, value);
        return true;
    }
    return false;
}

错误如下：

分析，可能是值的类型不对或长度太长了?

1、修改value 的长度以后错误仍然存在。

2、在分析是不是返回值的类型不对，改为Integer后，又抛出另一个错误

3、改为String类型以后错误仍然存在。

最后百度可能是值序列化的问题，

4、修改RedisConfig

@Bean
public RedisTemplate redisTemplate(RedisConnectionFactory factory) {
    RedisTemplate redisTemplate = new RedisTemplate();
    redisTemplate.setConnectionFactory(factory);
    return redisTemplate;
}
改为：

@Bean
public RedisTemplate redisTemplate(RedisConnectionFactory factory) {
    RedisTemplate redisTemplate = new RedisTemplate();
    redisTemplate.setConnectionFactory(factory);
    //key序列化
    redisTemplate.setKeySerializer(new StringRedisSerializer());
    //value序列化
    redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
    redisTemplate.afterPropertiesSet();
    return redisTemplate;
}

  嘿嘿，果然好了，但是所有的值都被序列化为String类型了,显然没有达到最初的要求

最终，直接改加锁的代码，最终改为

/**
 * 获取分布式锁
 *
 * @param lockKey     锁
 * @param requestId   请求标识
 * @param expireTime  单位秒|你认为此方法需要多少时间，设置一个最长时间，此时间必须大于需要调用锁的业务方法逻辑的最大时间，否则锁会冲突
 * @param waitTimeout 单位毫秒|如果拿不到锁，那么休眠，然后反反复复重试，直到拿到锁为止

 * @return 是否获取成功
 */
public boolean getLock(String lockKey, String requestId, long expireTime, long waitTimeout) {
    // 当前时间
    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("开始获取分布式锁-key[{}]", lockKey);
        int count = 0;
        RedisSerializer stringRedisSerializer = new StringRedisSerializer();
        List lockKeyList = Collections.singletonList(lockKey);
        do {
            RedisScript redisScript = new DefaultRedisScript(script, Long.class);
            logger.debug("尝试获取分布式锁-key[{}]requestId[{}]count[{}]", lockKey, requestId, count);

            Object result = redisTemplate.execute(redisScript, stringRedisSerializer, stringRedisSerializer, lockKeyList, requestId, expireTime + "");
            Long SUCCESS = 1L;
            if (SUCCESS.equals(result)) {
                logger.debug("尝试获取分布式锁-key[{}]成功", lockKey);
                return true;
            }
            //休眠200毫秒
            Thread.sleep(200L);
            count++;
        } while ((System.nanoTime() - nanoTime)     } catch (Exception e) {
        e.printStackTrace();
        logger.error("尝试获取分布式锁-key[{}]异常", lockKey);
        logger.error(e.getMessage(), e);
    }
    return false;
}

/**
 * 释放锁
 *
 * @param lockKey 锁
 * @param value   请求标识
 * @return 是否释放成功
 */
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 redisScript = new DefaultRedisScript(script, Long.class);
    RedisSerializer stringRedisSerializer = new StringRedisSerializer();
    Object result = redisTemplate.execute(redisScript, stringRedisSerializer, stringRedisSerializer, Collections.singletonList(lockKey), value);
    Long SUCCESS = 1L;
    if (SUCCESS.equals(result)) {
        logger.debug("释放锁成功key[{}]value[{}]", lockKey, value);
        return true;
    }
    return false;
}
在execute 执行语句直接序列化key 和 value 就完美解决了
