多库事务问题，2个库同时提交或同步滚回

   Db::connection('api_log')->beginTransaction();
        Db::connection('default')->beginTransaction();

        try {
            // 业务处理

            Db::connection('api_log')->commit();
            Db::connection('default')->commit();

        } catch (\Throwable $exception) {
            var_dump($exception);

            Db::connection('api_log')->rollBack();
            Db::connection('default')->rollBack();

        }
