jsp网上订票系统源代码

JSP（JavaServer Pages）是一种用于创建动态Web页面的技术，它允许开发者将Java代码嵌入到HTML页面中，从而实现动态内容的生成和交互。下面是一个简单的JSP网上订票系统的源代码示例，包括用户界面和后端逻辑的基本框架。

1. 项目结构

/WEB-INF
    /classes
        /com
            /example
                BookingServlet.java
    web.xml
/index.jsp
/bookTicket.jsp

2. `web.xml` 配置文件

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    version="3.1">
    <servlet>
        <servlet-name>BookingServlet</servlet-name>
        <servlet-class>com.example.BookingServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>BookingServlet</servlet-name>
        <url-pattern>/bookTicket</url-pattern>
    </servlet-mapping>
</web-app>

3. `index.jsp` 用户界面

<!DOCTYPE html>
<html>
<head>
    <title>网上订票系统</title>
</head>
<body>
    <h1>欢迎来到网上订票系统</h1>
    <form action="bookTicket" method="post">
        <label for="flightNumber">航班号:</label>
        <input type="text" id="flightNumber" name="flightNumber"><br><br>
        <label for="passengerName">乘客姓名:</label>
        <input type="text" id="passengerName" name="passengerName"><br><br>
        <input type="submit" value="订票">
    </form>
</body>
</html>

4. `BookingServlet.java` 后端逻辑

package com.example;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class BookingServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String flightNumber = request.getParameter("flightNumber");
        String passengerName = request.getParameter("passengerName");

        // 这里可以添加数据库操作来保存订票信息
        // 例如：BookingDAO.saveBooking(flightNumber, passengerName);

        response.sendRedirect("bookTicket.jsp?success=true&flightNumber=" + flightNumber + "&passengerName=" + passengerName);
    }
}

5. `bookTicket.jsp` 显示订票结果

<!DOCTYPE html>
<html>
<head>
    <title>订票结果</title>
</head>
<body>
    <% 
        String success = request.getParameter("success");
        if ("true".equals(success)) {
            String flightNumber = request.getParameter("flightNumber");
            String passengerName = request.getParameter("passengerName");
    %>
            <h1>订票成功！</h1>
            <p>航班号: <%= flightNumber %></p>
            <p>乘客姓名: <%= passengerName %></p>
    <% } else { %>
            <h1>订票失败，请重试。</h1>
    <% } %>
</body>
</html>
