How to use MySQL and Java to develop a simple online ticket booking system
Overview:
With the popularity and development of the Internet, the ticket booking system has become an aviation An essential tool for various activities such as , railways, movies, concerts, etc. This article will introduce how to use MySQL and Java to develop a simple online ticket booking system to help beginners understand and master this development method.
System requirements:
- Users can select the event they want to book tickets through the system and select seats.
- The system needs to record the user's personal information and order information.
- The system needs to update the optional status of seats in real time.
- The order payment process needs to be integrated into the system.
- Database design:
First, we need to create a database and design a table structure to store user information, order information and seat information. The following is an example of a simplified database table structure:
User table: used to store users' personal information.
- User_id (primary key)
- Name
- Password
Order table: used to store users order information.
- Order_id (primary key)
- User_id (foreign key)
- Activity_id (foreign key)
- Seat_id (foreign key)
- Status (order status)
Activity table: used to store activity information that can be booked.
- Activity_id (primary key)
- Activity_name
- Start_time
- End_time
Seat table: used to store seats information.
- Seat_id (primary key)
- Activity_id (foreign key)
- Seat_number
- Status (seat status)
- Java back-end development:
Next, we need to write the back-end code in Java to interact with the front-end page and operate the database. Here are some key backend code examples:
2.1 User login and registration
// 用户登录
public User login(String email, String password) {
// TODO: 根据email和password查询数据库获得用户对象
}
// 用户注册
public void register(User user) {
// TODO: 将用户对象插入到数据库中
}2.2 Event information retrieval and seat selection
// 获取可订票的活动列表
public List<Activity> getActivityList() {
// TODO: 查询数据库获取活动列表
}
// 获取座位状态
public Seat getSeatStatus(int seatId) {
// TODO: 根据座位id查询数据库获取座位对象
}
// 更新座位状态
public void updateSeatStatus(Seat seat) {
// TODO: 更新座位状态到数据库中
}
// 创建订单
public void createOrder(Order order) {
// TODO: 将订单对象插入到数据库中
}2.3 Order payment
// 获取订单信息
public Order getOrder(int orderId) {
// TODO: 根据订单id查询数据库获取订单对象
}
// 更新订单状态
public void updateOrderStatus(Order order) {
// TODO: 更新订单状态到数据库中
}
// 完成支付
public void completePayment(Order order) {
// TODO: 实现订单支付逻辑
}- Front-end development:
In front-end development, we can use HTML, CSS and JavaScript to create the user interface and interact with the back-end through JavaScript. The following is a simple front-end page example:
<!DOCTYPE html>
<html>
<head>
<title>在线订票系统</title>
<script src="jquery.min.js"></script>
<script>
// 获取活动列表
$.get("getActivityList", function(data) {
var activityList = JSON.parse(data);
// TODO: 根据活动列表创建页面元素
});
// 选择座位
function selectSeat(seatId) {
// TODO: 根据选择的座位更新页面显示和发送请求到后端
}
// 创建订单
function createOrder(userId, activityId, seatId) {
// TODO: 根据用户选择的座位创建订单并发送请求到后端
}
</script>
</head>
<body>
<h1>在线订票系统</h1>
<div id="activity-list">
<!-- 活动列表将在此处动态生成 -->
</div>
<div id="seat-list">
<!-- 座位列表将在此处动态生成 -->
</div>
<button onclick="createOrder(userId, activityId, seatId)">确认预订</button>
</body>
</html>Summary:
By using a combination of MySQL and Java to develop a simple online ticket booking system, we can better understand and master the system. Design and development process. This article provides database design, Java back-end and front-end code examples, hoping to provide some help to beginners when developing similar systems. Of course, this is just a simplified example, and more functions and security need to be considered in actual development.
