stringRedisTemplate.opsForValue().increment(key)报空指针异常

BUG复现满足以下条件可触发：
1.在RedisConfig开启Redis事务

 redisTemplate.setEnableTransactionSupport(true);

2.业务中开启事务

@Transactional

3.同一个业务下用生产多点id就报这个错误了

Cannot invoke "java.lang.Long.longValue()" because the return value of "org.springframework.data.redis.core.ValueOperations.increment(Object, long)" is null
