一、该问题的重现步骤是什么？

.getRedisTemplate().execute(SessionCallback() {
    Object execute(RedisOperations redisOperations) DataAccessException {
        String likeKey = RedisKeyKit.(, );
        String userLikeKey = RedisKeyKit.();

        isMember = redisOperations.opsForSet().isMember(likeKey, );

        redisOperations.multi();

        (!isMember) {
            redisOperations.opsForSet().add(likeKey, );
            redisOperations.opsForValue().increment(userLikeKey);
        } {
            redisOperations.opsForSet().remove(likeKey, );
            redisOperations.opsForValue().decrement(userLikeKey);
        }

        redisOperations.exec();
    }
});

String userLikeKey = RedisKeyKit.(userId);
.getCounter(userLikeKey);

二、你期待的结果是什么？实际看到的又是什么？

bladeRedis.getCounter(userLikeKey);
获取到正确得计数值

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

2.8

四、请提供详细的错误堆栈信息，这很重要。

我这样获取 bladeRedis.getRedisTemplate().opsForValue().increment(userLikeKey);设置值进去。
然后在Object obj = bladeRedis.getRedisTemplate().opsForValue().get(userLikeKey); 这样获取后还是报上面得错误

.execute(SessionCallback() {
    Object execute(RedisOperations redisOperations) DataAccessException {
        String likeKey = RedisKeyKit.(, );
        String userLikeKey = RedisKeyKit.();

        isMember = redisOperations.opsForSet().isMember(likeKey, );

        redisOperations.multi();

        (!isMember) {
            redisOperations.opsForSet().add(likeKey, );
            redisOperations.opsForValue().increment(userLikeKey);
        } {
            redisOperations.opsForSet().remove(likeKey, );
            redisOperations.opsForValue().decrement(userLikeKey);
        }

        redisOperations.exec();
    }
});

String userLikeKey = RedisKeyKit.(userId);
Object obj = .opsForValue().get(userLikeKey);
(Func.(obj)) {
    ;
} {
    Long.(String.(obj));
}
