苍穹外卖学习 Day08

前言

该篇博客用于记录苍穹外卖Day08地址、用户下单、订单支付的学习记录
(订单支付部分这里简化了逻辑)

地址

课程中这个模块的代码是直接导入的，这里我来从0开始敲一遍，思路大多通过注释写出

要完成地址功能的开发，涉及到以下接口设计：

查询当前登录用户的所有地址信息
新增地址
根据id查询地址
根据id修改地址
查询默认地址
根据id删除地址
设置默认地址

注意：

1.代码全由我自己开发，可能与提供的资料有所不同，但功能实现都没问题，仅做参考
2.接口文档有一个小错误。在设置默认地址接口，接口文档中的参数是id，这里要是AddressBook，不然无法接收到参数
3.在设置默认地址接口中，资料提供的方法我认为较麻烦，我这里是直接先根据默认地址is_default=1的性质将其变为0，再根据id将我们要变更的默认地址的is_default设为1

接下来正式开始开发：

用户下单

在该接口，我只分析一下OrderServiceImpl层的代码。完成用户下单功能开发有以下步骤：

要向订单表和订单明细表插入数据之前，先要对异常情况进行处理（地址薄为空、购物车为空）
封装好Orders对象来进行数据库操作
向订单表和订单明细表插入数据
订单完成，清空购物车
封装OrderSubmitVO，返回给前端

@Service
public class OrderServiceImpl implements OrderService {
    @Autowired
    private OrderMapper orderMapper;
    @Autowired
    private OrderDetailMapper orderDetailMapper;
    @Autowired
    private ShoppingCartMapper shoppingCartMapper;
    @Autowired
    private AddressBookMapper addressBookMapper;

    //用户下单
    @Override
    public OrderSubmitVO submit(OrdersSubmitDTO ordersSubmitDTO) {
        //先处理各种业务异常（地址薄为空、购物车为空）
        AddressBook addressBook=addressBookMapper.getById1(ordersSubmitDTO.getAddressBookId());
        if(addressBook==null){
            throw new AddressBookBusinessException(MessageConstant.ADDRESS_BOOK_IS_NULL);
        }
        ShoppingCart shoppingCart=new ShoppingCart();
        shoppingCart.setUserId(BaseContext.getCurrentId());
        List<ShoppingCart> shoppingCarts=shoppingCartMapper.list(shoppingCart);
        if(shoppingCarts==null||shoppingCarts.size()==0){
            throw new ShoppingCartBusinessException(MessageConstant.SHOPPING_CART_IS_NULL);
        }

        //封装好Orders对象
        Orders orders=new Orders();
        BeanUtils.copyProperties(ordersSubmitDTO,orders);
        orders.setUserId(BaseContext.getCurrentId());
        orders.setOrderTime(LocalDateTime.now());
        orders.setPayStatus(Orders.UN_PAID);//未支付
        orders.setStatus(Orders.PENDING_PAYMENT);//待付款
        orders.setNumber(String.valueOf(System.currentTimeMillis()));
        orders.setPhone(addressBook.getPhone());
        orders.setConsignee(addressBook.getConsignee());
        //向订单表插入数据（1条）
        orderMapper.insert(orders);

        //获取订单明细表的orderId
        Long id= orders.getId();
        //向订单明细表插入数据（n条），获取购物车中的数据插进订单明细表
        List<OrderDetail> detailList=new ArrayList<>();
        for (ShoppingCart cart : shoppingCarts) {
            OrderDetail orderDetail=new OrderDetail();
            orderDetail.setOrderId(id);
            BeanUtils.copyProperties(cart,orderDetail);

            detailList.add(orderDetail);
        }
        orderDetailMapper.insertBatch(detailList);

        //订单完成，清空购物车
        shoppingCartMapper.delete(shoppingCart);

        //封装OrderSubmitVO，返回给前端
        OrderSubmitVO orderSubmitVO=new OrderSubmitVO();
        orderSubmitVO.setId(orders.getId());
        orderSubmitVO.setOrderTime(orders.getOrderTime());
        orderSubmitVO.setOrderAmount(orders.getAmount());
        orderSubmitVO.setOrderNumber(orders.getNumber());

        return orderSubmitVO;
    }
}

订单支付

在该模块你可以按照老师的操作申请各种东西来做，原谅我这里为了简化逻辑，点击支付我就直接修改订单状态了。

OrderController

	@PutMapping("/payment")
    @ApiOperation("订单支付")
    public Result<OrderPaymentVO> payment(@RequestBody OrdersPaymentDTO ordersPaymentDTO) throws Exception {
        log.info("订单支付：{}", ordersPaymentDTO);
        orderService.paySuccess(ordersPaymentDTO.getOrderNumber());

        return Result.success();
    }

OrderServiceImpl

	//支付成功，修改订单数据
    public void paySuccess(String outTradeNo) {

        // 根据订单号查询订单
        Orders ordersDB = orderMapper.getByNumber(outTradeNo);

        // 根据订单id更新订单的状态、支付方式、支付状态、结账时间
        Orders orders = Orders.builder()
                .id(ordersDB.getId())
                .status(Orders.TO_BE_CONFIRMED)
                .payStatus(Orders.PAID)
                .checkoutTime(LocalDateTime.now())
                .build();

        orderMapper.update(orders);
    }

OrderMapper

    //根据订单号查询订单
    @Select("select * from orders where number = #{orderNumber}")
    Orders getByNumber(String orderNumber);

	//修改订单信息
    void update(Orders orders);

OrderMapper.xml

	<update id="update" parameterType="com.sky.entity.Orders">
        update orders
        <set>
            <if test="cancelReason != null and cancelReason!='' ">
                cancel_reason=#{cancelReason},
            </if>
            <if test="rejectionReason != null and rejectionReason!='' ">
                rejection_reason=#{rejectionReason},
            </if>
            <if test="cancelTime != null">
                cancel_time=#{cancelTime},
            </if>
            <if test="payStatus != null">
                pay_status=#{payStatus},
            </if>
            <if test="payMethod != null">
                pay_method=#{payMethod},
            </if>
            <if test="checkoutTime != null">
                checkout_time=#{checkoutTime},
            </if>
            <if test="status != null">
                status = #{status},
            </if>
            <if test="deliveryTime != null">
                delivery_time = #{deliveryTime}
            </if>
        </set>
        where id = #{id}
    </update>
