记操作redis incr初始化数据问题

直接用increment自增多少初始化，不能用set，否则操作incr时会出现问题，报错类型不匹配

@PostConstruct
public void init() {
    Long maxIdDb = paymentLogMapper.findMaxId();
    if (maxIdDb == null) {
        //incr会自己初始化并自增
        return;
    }
    String key = Constants.PAYMENT_LOG_MAX_ID;
    Long value = redisService.getCacheObject(key);
    if (value == null) {
        redisService.incrBy(key, maxIdDb);
    } else if (maxIdDb - value != 0) {
        redisService.incrBy(key, maxIdDb - value);
    }
}

@Override
public PaymentLog createPaymentLog() {
    Long maxId = redisService.incrBy(Constants.PAYMENT_LOG_MAX_ID, 1L);
    PaymentLog paymentLog = new PaymentLog();
    paymentLog.setId(IdUtils.genPaymentLogId());
    return paymentLog;
}
