导入地址相关代码

• 导入资料文件夹下day08下的地址相关代码

用户下单

• 创建OrderController类，并且添加用户下单方法submit
• OrderController.java

package com.sky.controller.user;

import com.sky.dto.OrdersSubmitDTO;
import com.sky.result.Result;
import com.sky.service.OrderService;
import com.sky.vo.OrderSubmitVO;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController("userOrderController")
@RequestMapping("/user/order")
@Api(tags = "用户端订单相关接口")
@Slf4j
public class OrderController {

    @Autowired
    private OrderService orderService;
    /**
     *
     * @param ordersSubmitDTO
     * @return
     */
    @PostMapping("/submit")
    @ApiOperation("用户下单")
    public Result<OrderSubmitVO> submit(@RequestBody OrdersSubmitDTO ordersSubmitDTO){
        log.info("用户下单:{}",ordersSubmitDTO);
        OrderSubmitVO orderSubmitVO = orderService.submitOrder(ordersSubmitDTO);
        return Result.success(orderSubmitVO);
    }
}

• 创建OrderService接口类，并且实现类中实现
• OrderServiceImpl.java

package com.sky.service.impl;

import com.sky.constant.MessageConstant;
import com.sky.context.BaseContext;
import com.sky.dto.OrdersSubmitDTO;
import com.sky.entity.AddressBook;
import com.sky.entity.OrderDetail;
import com.sky.entity.Orders;
import com.sky.entity.ShoppingCart;
import com.sky.exception.AddressBookBusinessException;
import com.sky.exception.ShoppingCartBusinessException;
import com.sky.mapper.AddressBookMapper;
import com.sky.mapper.OrderDetailMapper;
import com.sky.mapper.OrderMapper;
import com.sky.mapper.ShoppingCartMapper;
import com.sky.service.OrderService;
import com.sky.vo.OrderSubmitVO;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.time.LocalDateTime;
import java.util.ArrayList;
import java.util.List;

@Service
public class OrderServiceImpl implements OrderService {

    @Autowired
    private OrderMapper orderMapper;
    @Autowired
    private OrderDetailMapper orderDetailMapper;
    @Autowired
    private AddressBookMapper addressBookMapper;
    @Autowired
    private ShoppingCartMapper shoppingCartMapper;
    /**
     * 用户下单
     * @param ordersSubmitDTO
     * @return
     */
    @Override
    @Transactional
    public OrderSubmitVO submitOrder(OrdersSubmitDTO ordersSubmitDTO) {
        //处理异常：地址为空，购物车为空
        AddressBook addressBook = addressBookMapper.getById(ordersSubmitDTO.getAddressBookId());
        if(addressBook == null){
            throw new AddressBookBusinessException(MessageConstant.ADDRESS_BOOK_IS_NULL);
        }
        Long currentId = BaseContext.getCurrentId();
        ShoppingCart shoppingCart = new ShoppingCart();
        shoppingCart.setUserId(currentId);
        List<ShoppingCart> shoppingCartList = shoppingCartMapper.list(shoppingCart);
        if(shoppingCartList == null || shoppingCartList.size() == 0){
            throw new ShoppingCartBusinessException(MessageConstant.SHOPPING_CART_IS_NULL);
        }
        //向订单表插入一条
        Orders orders = new Orders();
        BeanUtils.copyProperties(ordersSubmitDTO,orders);
        orders.setOrderTime(LocalDateTime.now());
        orders.setPayStatus(Orders.UN_PAID);
        orders.setAddress(addressBookMapper.getById(orders.getAddressBookId()).getDetail());
        orders.setStatus(Orders.PENDING_PAYMENT);
        orders.setNumber(String.valueOf(System.currentTimeMillis()));
        orders.setPhone(addressBook.getPhone());
        orders.setConsignee(addressBook.getConsignee());
        orders.setUserId(currentId);
        orderMapper.insert(orders);
        //向订单明细表插入N条
        List<OrderDetail> orderDetailList = new ArrayList<>();
        for (ShoppingCart cart : shoppingCartList){
            OrderDetail orderDetail = new OrderDetail();
            BeanUtils.copyProperties(cart,orderDetail);
            orderDetail.setOrderId(orders.getId());
            orderDetailList.add(orderDetail);
        }
        orderDetailMapper.insertBatch(orderDetailList);
        //清空购物车
        shoppingCartMapper.deleteByUserId(currentId);
        //封装VO
        OrderSubmitVO orderSubmitVO = OrderSubmitVO.builder()
                .id(orders.getId())
                .orderTime(orders.getOrderTime())
                .orderNumber(orders.getNumber())
                .orderAmount(orders.getAmount())
                .build();
        return orderSubmitVO;
    }
}

• 创建OrderMapper,OrderDetailMapper接口类，并且xml中实现
• OrderMapper.xml

    <insert id="insert" useGeneratedKeys="true" keyProperty="id">
        insert into orders(number, status, user_id, address_book_id, order_time, checkout_time, pay_method, pay_status,amount, remark, phone, address,  consignee,  estimated_delivery_time, delivery_status,pack_amount,tableware_number, tableware_status)
        values
            (#{number},#{status},#{userId},#{addressBookId},#{orderTime},#{checkoutTime},#{payMethod},#{payStatus},#{amount},#{remark},#{phone},#{address},#{consignee},#{estimatedDeliveryTime},#{deliveryStatus},#{packAmount},#{tablewareNumber},#{tablewareStatus})
    </insert>

• OrderDetailMapper.xml

    <insert id="insertBatch">
        insert into order_detail(name, image, order_id, dish_id, setmeal_id, dish_flavor, number, amount)
            values
        <foreach collection="orderDetailList" item="od" separator=",">
            (#{od.name},#{od.image},#{od.orderId},#{od.dishId},#{od.setmealId},#{od.dishFlavor},#{od.number},#{od.amount})
        </foreach>
    </insert>

订单支付

• 安装cpolar，windows下运行方式为，进入安装目录cmd，先输入cpolar.exe authtoken 你的token，再cpolar.exe http 端口号就可运行
• 考虑到缺少支付文件，决定自行写一个模拟下单功能，即小程序点击支付后直接显示支付成功即可
• controller层接受前端参数
• OrderController.java

    @PutMapping("/payment")
    @ApiOperation("订单支付")
    public Result payment(@RequestBody OrdersPaymentDTO ordersPaymentDTO) throws Exception {
        log.info("订单支付：{}", ordersPaymentDTO);
        orderService.payment(ordersPaymentDTO);
        log.info("模拟支付成功");
        return Result.success();
    }

• OrderService接口类添加支付方法，并且实现类中实现
• OrderServiceImpl.java

    @Override
    public void payment(OrdersPaymentDTO ordersPaymentDTO) {
        //下单时直接根据用户id更新订单状态为已支付
        Long currentId = BaseContext.getCurrentId();

        // 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()
                .userId(currentId)
                .status(Orders.TO_BE_CONFIRMED)
                .payStatus(Orders.PAID)
                .checkoutTime(LocalDateTime.now())
                .build();

        orderMapper.updateByUserId(orders);
    }

• OrderMapper接口类增更新方法，并且xml中实现
• OrderMapper.xml

    <update id="updateByUserId">
        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 user_id = #{userId}
    </update>
