Service层

创建AddressBookService.java

package com.sky.service;

import com.sky.entity.AddressBook;
import java.util.List;

public interface AddressBookService {

    List<AddressBook> list(AddressBook addressBook);

    void save(AddressBook addressBook);

    AddressBook getById(Long id);

    void update(AddressBook addressBook);

    void setDefault(AddressBook addressBook);

    void deleteById(Long id);

}

创建AddressBookServiceImpl.java

package com.sky.service.impl;

@Service
@Slf4j
public class AddressBookServiceImpl implements AddressBookService {
    @Autowired
    private AddressBookMapper addressBookMapper;

    /**
     * 条件查询
     *
     * @param addressBook
     * @return
     */
    public List<AddressBook> list(AddressBook addressBook) {
        return addressBookMapper.list(addressBook);
    }

    /**
     * 新增地址
     *
     * @param addressBook
     */
    public void save(AddressBook addressBook) {

    public void update(AddressBook addressBook) {
        addressBookMapper.update(addressBook);
    }

    /**

     * @param id
     */
    public void deleteById(Long id) {
        addressBookMapper.deleteById(id);
    }

}

Mapper层

创建AddressBookMapper.java

package com.sky.mapper;

@Mapper
public interface AddressBookMapper {

    /**
     * 条件查询
     * @param addressBook
     * @return
     */
    List<AddressBook> list(AddressBook addressBook);

    /**
     * 新增
     * @param addressBook
     */
    @Insert("insert into adress_book" +
            "        (user_id, consignee, phone, sex, province_code, province_name, city_code, city_name, district_code," +
            "         district_name, detail, label, is_default)" +
            "        values (#{userId}, #{consignee}, #{phone}, #{sex}, #{provinceCode}, #{provinceName}, #{cityCode}, #{cityName}," +
            "                #{districtCode}, #{districtName}, #{detail}, #{label}, #{isDefault})")
    void insert(AddressBook addressBook);

    /**
     * 根据id查询
     * @param id
     * @return
     */
    @Select("select * from address_book where id = #{id}")
    AddressBook getById(Long id);

    /**
     * 根据id修改
     * @param addressBook
     */
    void update(AddressBook addressBook);

    /**
     * 根据 用户id修改 是否默认地址
     * @param addressBook
     */
    @Update("update address_book set is_default = #{isDefault} where user_id = #{userId}")
    void updateIsDefaultByUserId(AddressBook addressBook);

    /**
     * 根据id删除地址
     * @param id
     */
    @Delete("delete from address_book where id = #{id}")
    void deleteById(Long id);

}

创建AddressBookMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.sky.mapper.AddressBookMapper">

    <select id="list" parameterType="AddressBook" resultType="AddressBook">
        select * from address_book
        <where>
            <if test="userId != null">
                and user_id = #{userId}
            </if>
            <if test="phone != null">
                and phone = #{phone}
            </if>
            <if test="isDefault != null">
                and is_default = #{isDefault}
            </if>
        </where>
    </select>

    <update id="update" parameterType="addressBook">
        update address_book
        <set>
            <if test="consignee != null">
                consignee = #{consignee},
            </if>
            <if test="sex != null">
                se = #{sex},
            </if>

                phone = #{phone},
            </if>
            <if test="detail != null">
                detail = #{detail},
            </if>
            <if test="label != null">
                label = #{label},
            </if>
            <if test="isDefault != null">
                is_default = #{isDefault},
            </if>
        </set>
        where id = #{id}
    </update>

</mapper>

2. 用户下单

Controller层

package com.sky.controller.user;

/**
 * 订单
 */
@RestController("userOrderController")
@RequestMapping("/user/order")
@Slf4j
@Api(tags = "C端-订单接口")
public class OrderController {

    @Autowired
    private OrderService orderService;

    /**
     * 用户下单
     *
     * @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);
    } 

}

Service层

创建OrderService接口，并声明用户下单方法：

package com.sky.service;

public interface OrderService {

    /**
     * 用户下单
     * @param ordersSubmitDTO
     * @return
     */
    OrderSubmitVO submitOrder(OrdersSubmitDTO ordersSubmitDTO);
}

创建OrderServiceImpl实现OrderService接口：

package com.sky.service.impl;

/**
 * 订单
 */
@Service
@Slf4j
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
     *
     * @param ordersSubmitDTO
     * @return
     */
    @Transactional
    public OrderSubmitVO submitOrder(OrdersSubmitDTO ordersSubmitDTO) {
        //异常情况的处理（收货地址为空、超出配送范围、购物车为空）
        AddressBook addressBook = addressBookMapper.getById(ordersSubmitDTO.getAddressBookId());
        if (addressBook == null) {
            throw new AddressBookBusinessException(MessageConstant.ADDRESS_BOOK_IS_NULL);
        }

        Long userId = BaseContext.getCurrentId();
        ShoppingCart shoppingCart = new ShoppingCart();
        shoppingCart.setUserId(userId);

        //查询当前用户的购物车数据
        List<ShoppingCart> shoppingCartList = shoppingCartMapper.list(shoppingCart);
        if (shoppingCartList == null || shoppingCartList.size() == 0) {
            throw new ShoppingCartBusinessException(MessageConstant.SHOPPING_CART_IS_NULL);
        }

        //构造订单数据
        Orders order = new Orders();
        BeanUtils.copyProperties(ordersSubmitDTO,order);
        order.setPhone(addressBook.getPhone());
        order.setAddress(addressBook.getDetail());
        order.setConsignee(addressBook.getConsignee());
        order.setNumber(String.valueOf(System.currentTimeMillis()));
        order.setUserId(userId);
        order.setStatus(Orders.PENDING_PAYMENT);
        order.setPayStatus(Orders.UN_PAID);
        order.setOrderTime(LocalDateTime.now());

        //向订单表插入1条数据
        orderMapper.insert(order);

        //订单明细数据
        List<OrderDetail> orderDetailList = new ArrayList<>();
        for (ShoppingCart cart : shoppingCartList) {
            OrderDetail orderDetail = new OrderDetail();
            BeanUtils.copyProperties(cart, orderDetail);
            orderDetail.setOrderId(order.getId());
            orderDetailList.add(orderDetail);
        }

        //向明细表插入n条数据
        orderDetailMapper.insertBatch(orderDetailList);

        //清理购物车中的数据
        shoppingCartMapper.deleteByUserId(userId);

        //封装返回结果
        OrderSubmitVO orderSubmitVO = OrderSubmitVO.builder()
                .id(order.getId())
                .orderNumber(order.getNumber())
                .orderAmount(order.getAmount())
                .orderTime(order.getOrderTime())
                .build();

        return orderSubmitVO;
    }
    
}

Mapper层

OrderMapper.java

package com.sky.mapper;

@Mapper
public interface OrderMapper {
    /**
     * 插入订单数据
     * @param order
     */
    void insert(Orders order);
}

OrderMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.sky.mapper.OrderMapper">

    <insert id="insert" parameterType="Orders" 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, consigee, estimated_delivery_time,
         delivery_status, pack_amount, tablewae_number,tableware_status)
        values (
        #{number}, #{status}, #{userId}, #{addressBookId}, #{orderTime},
        #{checkoutTime}, #{payMethod},#{payStatus}, #{amount}, #{remark}, 
        #{phone}, #{address}, #{consignee},#{estimatedDeliveryTime}, #{deliveryStatus},
        #{packAmount}, #{tablewareNumber}, #{tablewareStatus})
    </insert>
</mapper>

创建OrderDetailMapper接口和对应的xml映射文件：

OrderDetailMapper.java

package com.sky.mapper;

import com.sky.entity.OrderDetail;
import java.util.List;

@Mapper
public interface OrderDetailMapper {

    /**
     * 批量插入订单明细数据
     * @param orderDetails
     */
    void insertBatch(List<OrderDetail> orderDetails);

}

OrderDetailMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.sky.mapper.OrderDetailMapper">

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

</mapper>

3. 订单支付
