JavaWeb-仿小米商场(8) 订单支付[沙箱支付],用户订单列表

1 功能描述

接上篇 JavaWeb - 仿小米商城（7）：创建订单

实现点击支付宝支付按钮完成对应支付操作通过使用支付宝沙箱支付模拟用户支付,沙箱支付的逻辑可

参考博客:https://blog.csdn.net/hhb442/article/details/123304287

支付提示界面:当点击提交页面,此时将订单数据存储到数据表中

支付成功可以通过我的订单查看订单

2 提交订单功能分析

2.1 功能逻辑抽象

商品购物车点击生成订单时,先判断用户是否登录,如果用户没有登录,则需要用户先完成登录 ,获取到用户对象,然后从购物车session中取得购物车数据,根据购物车数据创建订单对象和订单详情列表list集合

商品购物车是面向数据库中的 tb_order表和订单详情表tb_orderDetail，在订单预览界面添加数据到数据库中对应的表,

购物车建立对应的 CartServlet 类、CartService 接口和实现类、CartDao 接口和实现类。

订单建立对应的 OrderServlet 类、OrderService 接口和实现类、OrderDao 接口和实现类。

订单详情对应的 OrderDetailServlet 类、OrderDetailService 接口和实现类、OrderDetailDao 接口和实现类。

提示:好需要创建辅助的vo类

订单列表的显示需要一个vo类,其中包含订单信息和地址信息以及用户信息

OrderView : oid uid orderTime userName telphon address totalMoney ostate

GoodOrdersDetailVo: pid pimg pname star pubdate, price num money

3.1 沙箱支付实现

点击支付跳转至支付页面, 通过手机支付宝沙箱app扫码支付

扫码支付成功后会跳转到成功页面

4 用户订单列表

4.1:用户订单列表链接修改

订单列表页面orderList.html页面ajax请求的的js代码用于在页面加载完成时根据数据库数据渲染页面

<script>//获取购物车列表$(document).ready(function () {//获取session数据显示到页面$.get("order.do?action=showMyOrder", "", function (result) {var index = 0;if (result.flag === true) {//登录for (var i in result.data) {index++;var money = result.data[i].quantity * result.data[i].price;var temp ='                    <tr>' +'                        <td>' + index + '</td>' +'                        <td>' + result.data[i].oid + '</td>' +'                        <td>' + result.data[i].totalMoney + '</td>' +'                        <td>' +'                            <font color="red">';var statu = "";if (result.data[i].ostate == 0) {statu = "未支付"}if (result.data[i].ostate == 1) {statu = "已支付"}if (result.data[i].ostate == 2) {statu = "待发货"}if (result.data[i].ostate == 3) {statu = "待收货"}if (result.data[i].ostate == 4) {statu = "待评价"}temp += statu;temp += '                            </font>' +'                        </td>' +'                        <td>' + result.data[i].orderTime + '</td>' +'                        <td>' + result.data[i].address + '</td>' +'                        <td>' +'                            <button type="button" class="btn btn-danger btn-sm" οnclick="showOrder(\'' + result.data[i].oid + '\')">' +'                                订单详情' +'                            </button>';var str = ' <button type="button" class="btn btn-warning btn-sm"' +'   οnclick="changeStatus(\'' + result.data[i].oid + '\')">确认收货' +'   </button>';temp += str;temp +='                        </td>' +'                    </tr>' +$("#orderBody").append(temp)$("#utip").text(result.data[i].userName);}} else {var error = "<tr><td colspan='7'>订单空空如也</td></tr>"$("#orderBody").append(error)}$("#sizetip").text(index);});});</script>

4.2后端

4.2.1后端OrderServlet

在 AddressServlet类中根据购物车信息创建订单数据

 @WebServlet("/order.do")
public class OrderServlet extends BaseServlet {private ResultData resultData = new ResultData();/*** 显示我的订单信息** @param req* @param resp* @return* @throws ServletException* @throws IOException*/public String showMyOrder(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {resultData.setData(true);HttpSession session = req.getSession();User user = (User) session.getAttribute(Constants.LOGINUSER);System.err.println(user);if (user == null) {resultData.setData(false);} else {IOrderService orderService = new OrderServiceImpl();List<OrderView> olist = orderService.queryAllDataByUId(user.getId());if (olist != null && !olist.isEmpty()) {resultData.setFlag(true);resultData.setData(olist);}else{resultData.setFlag(false);}}String json = JSON.toJSONString(resultData);resp.setContentType("application/json;charset=utf-8");return json;}
}

4.2.2 OrdarDaoImpl

订单表的dao层实现

public class OrderDaoImpl implements IOrderDao {//........./*** 通过id查询OrderView视图类得数据查询方法* @param uid* @return*/
@Overridepublic List<OrderView> queryAllDataByUId(int uid) {String sql = " select o.id as oid ,o.uid as uid,u.username as userName, o.time as orderTime, " +" a.phone as telphon,a.detail as address,o.status as ostate ,o.money as totalMoney from tb_user u,tb_order o,tb_address a " +" where o.uid=? and o.uid=u.id and o.aid=a.id; ";List<OrderView> query = null;QueryRunner run = new QueryRunner(DBUtils.getDataSource());try {query = run.query(sql, uid, new BeanListHandler<>(OrderView.class));} catch (SQLException e) {e.printStackTrace();}return query;
//....}

4.2.3 编写OrderServiceImpl代码

订单创建涉及到多张数据表,必须做事务控制：

public class OrderServiceImpl implements IOrderService {//......@Overridepublic List<OrderView> queryAllDataByUId(int uid) {return  orderDao.queryAllDataByUId(uid);}//......
}

   e.printStackTrace();}return query;

//…
}


#### 4.2.3 编写OrderServiceImpl代码订单创建涉及到多张数据表,必须做事务控制：```java
public class OrderServiceImpl implements IOrderService {//......@Overridepublic List<OrderView> queryAllDataByUId(int uid) {return  orderDao.queryAllDataByUId(uid);}//......
}
