大家好,又见面了,我是你们的朋友全栈君。

订单详情功能(提交订单支付界面)

原理分析

步骤实现:

1、准备工作:order_list.jsp当中修改链接

提交当前订单编号

代码语言:javascript复制
<a href="${pageContext.request.contextPath}/OrderServlet?method=findOrderByOid&oid=${o.oid}">付款</a>
2、OrderServlet —> findOrderByOid

获取订单的oid 调用业务层功能;根据订单编号查询订单信息 将订单放入request当中 转发到/jsp/order_info.jsp

OrderServlet当中实现该方法

代码语言:javascript复制
// findOrderByOid
	public String findOrderByOid(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException, SQLException { 
   
		//获取对应订单的oid
		String oid = request.getParameter("oid");
		//调用业务层功能:根据订单编号查询订单信息
		
		OrderService orderService = new OrderServiceImpl();
		Order order = null;
		try { 
   
			order = orderService.findOrderByOid(oid);
		} catch (Exception e) { 
   
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		//将订单放入到request当中
		request.setAttribute("order", order);
		//转发到/jsp/order_info.jsp
		return "/jsp/order_info.jsp";
	}
3、OrderService<->OrderServiceImpl

OrderService

代码语言:javascript复制
Order findOrderByOid(String oid)throws Exception;

OrderServiceImpl

代码语言:javascript复制
@Override
	public Order findOrderByOid(String oid) throws Exception { 
   	
		OrderDao orderDao = new OrderDaoImpl();	
		return orderDao.findOrderByOid(oid);
	}
4、OrderDao<->OrderDaoImpl

OrderDao

代码语言:javascript复制
Order findOrderByOid(String oid)throws Exception;

OrderDaoImpl 根据订单oid查询订单下所有的订单项以及订单项关联的商品

代码语言:javascript复制
@Override
	public Order findOrderByOid(String oid) throws Exception { 
   
		// 根据订单oid查询订单以及对应的订单项,返回订单,其订单包括订单以及订单项的集合
		String sql = "select * from orders where oid = ?";
		QueryRunner qr = new QueryRunner(JDBCUtils.getDataSource());
		Order order = qr.query(sql, new BeanHandler<Order>(Order.class), oid);
		// 根据订单的id 查询订单下所有订单项以及所有的订单对应的商品信息
		sql = "select * from orderitem o,product p where o.pid=o.pid where and oid = ?";
		List<Map<String, Object>> list02 = qr.query(sql, new MapListHandler(), oid);// 获取到的是笛卡尔集的所有对应的商品集合
		// 遍历list集合
		for (Map<String, Object> map : list02) { 
   
			// 实例化
			OrderItem orderItem = new OrderItem();
			Product product = new Product();
			// 由于BeanUtlis将字符串“1992-3-3”向user对象的setBithday();方法传递参数有问题,手动向BeanUtils注册一个时间类型转换器
			// 1、创建时间类型的转换器
			DateConverter dt = new DateConverter();
			// 2、设置转换的格式
			dt.setPattern("yyyy-MM-dd");
			// 3、注册转换器
			ConvertUtils.register(dt, Date.class);// 将Date对象设置为dt当中的格式
			try { 
   
				// 将map中属于orderItem的数据自动填充到orderItem对象上
				BeanUtils.populate(orderItem, map);
				// 将map中属于product的数据自动填充到product对象上
				BeanUtils.populate(product, map);
				// 让每一个订单项和商品项发生关系
				orderItem.setProduct(product);// 将商品项当中的内容放到订单项当中
				order.getList().add(orderItem);// 将订单项放到订单当中的list集合当中
			} catch (IllegalAccessException e) { 
   
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (InvocationTargetException e) { 
   
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		return order;
	}

5、/jsp/order_info.jsp 开发中:多个功能对应同一个jsp页面,为了提供代码的复用率,所有的功能在向同一个jsp页面转发的时候,向request当中存入相同的数据(属性名一致)request.setAttribute(name,obj);

代码语言:javascript复制
<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"  prefix="c"%>
<!doctype html>
<html>
	<head>
		<meta charset="utf-8" />
		<meta name="viewport" content="width=device-width, initial-scale=1">

		<script src="${pageContext.request.contextPath}/js/bootstrap.min.js" type="text/javascript"></script>
		<!-- 引入自定义css文件 style.css -->
		<link rel="stylesheet" href="${pageContext.request.contextPath}/css/style.css" type="text/css"/>
		<style>
			body { 
   
				margin-top: 20px;
				margin: 0 auto;
			}
			
			.carousel-inner .item img { 
   
				width: 100%;
				height: 300px;
			}
		</style>
	</head>

	<body>	
			<!--

            -->
			<%@include file="/jsp/header.jsp" %>
		<div class="container">
