TP5 模型事务操作

注意：数据只要涉及多表一致性操作，必须要开启数据库事务操作

ThinkPHP5 中模型层中使用事务：

        try{
            $this->startTrans();
            $this->data($order_data)->isUpdate(false)->save();
            $new_order = $this->order_no;
            if (!is_numeric($new_order)) throw new \Exception("商品订单添加失败");
            $this->hasMany('OrdersAccess', 'order_no', 'order_no')->saveAll($data_order);
            $this->commit();
            return ['code' => '1001', 'msg' => '商品订单添加成功', 'data' => ['order_no' => $new_order, 'cart_list' => $data_order]];

        }catch (\Exception $e){
            $this->rollback();
            return ['code'=>'1008','msg'=>'商品订单添加失败','data'];
        }
