前言

本篇博客主要是用户端的功能完善
主要是三个功能
1.导入地址簿 2.点击去结算弹出结算页面 3.微信支付功能
在这里插入图片描述

导入地址簿代码导入

这个地址簿就是一个表的CRUD，所以我们直接导入了

需求分析

一个业务功能可能对应多个接口，比如修改地址这个业务功能
其实对应查询回显+修改两个接口
在这里插入图片描述
看下数据库设计，具体的接口设计就不展示了

代码导入

把对应文件放入对应包然后进行编译即可
在这里插入图片描述

功能测试

自己测试一下喽
新增修改删除都测试一下

用户下单

接口设计

先看这个现实原型

主要看一下service的逻辑
controller

@RestController("userOrderController")//起个bean的别名因为等会再admin也会创建一个controller
@Slf4j
@RequestMapping("/user/order")
@Api(tags = "用户端订单相关接口")
public class OrderController {@Autowiredprivate 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，参数为:{}",ordersSubmitDTO);OrderSubmitVO orderSubmitVO = orderService.submitOrder(ordersSubmitDTO);return Result.success(orderSubmitVO);}}

service重量级

@Service
public class OrderServiceImpl implements OrderService {@Autowiredprivate OrderMapper orderMapper;@Autowiredprivate OrderDetailMapper orderDetailMapper;@Autowiredprivate AddressBookMapper addressBookMapper;@Autowiredprivate ShoppingCartMapper shoppingCartMapper;/*** 用户下单* @param ordersSubmitDTO* @return*/public OrderSubmitVO submitOrder(OrdersSubmitDTO ordersSubmitDTO) {//业务异常处理（为空地址簿）AddressBook addressBook = addressBookMapper.getById(ordersSubmitDTO.getAddressBookId());if(addressBook == null){throw new AddressBookBusinessException(MessageConstant.ADDRESS_BOOK_IS_NULL);}//业务异常处理（购物车数据为空）ShoppingCart shoppingCart = new ShoppingCart();Long userId = BaseContext.getCurrentId();shoppingCart.setUserId(userId);List<ShoppingCart> list = shoppingCartMapper.list(shoppingCart);//至少查询对应用户的购物车if(list == null){throw new ShoppingCartBusinessException(MessageConstant.SHOPPING_CART_IS_NULL);}//1.向订单表插入一条数据Orders orders = new Orders();//自己去看下Orders里面定义的一些常量BeanUtils.copyProperties(ordersSubmitDTO,orders);orders.setOrderTime(LocalDateTime.now());//下单时间设置orders.setPayStatus(Orders.UN_PAID);orders.setStatus(Orders.PENDING_PAYMENT);//设置订单为待付款orders.setNumber(String.valueOf(System.currentTimeMillis()));orders.setPhone(addressBook.getPhone());orders.setConsignee(addressBook.getConsignee());orders.setUserId(userId);orderMapper.insert(orders);List<OrderDetail> orderDetailList = new ArrayList<>();//2.向订单明细表插入n条数据for (ShoppingCart cart : list) {OrderDetail orderDetail = new OrderDetail();//订单明细BeanUtils.copyProperties(cart,orderDetail);orderDetail.setOrderId(orders.getId());//设置当前订单明细关联的订单idorderDetailList.add(orderDetail);}orderDetailMapper.insertBatch(orderDetailList);//批量插入//3.清空用户的购物车数据shoppingCartMapper.deleteByUserId(userId);//4.封装VO返回结果OrderSubmitVO orderSubmitVO = OrderSubmitVO.builder().id(orders.getId()).orderTime(orders.getOrderTime()).orderNumber(orders.getNumber()).orderAmount(orders.getAmount()).build();return orderSubmitVO;}
}

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>

orderMapper.xml
