java火车订票系统

### 使用Java实现火车订票系统

#### 设计思路与技术选型
为了构建一个高效的火车订票系统，选择合适的技术栈至关重要。该系统将采用Spring Boot框架作为主要开发工具，并选用MySQL数据库来存储数据[^2]。

#### 功能模块划分
整个系统可以分为多个核心功能模块：

- **用户管理**
用户注册、登录验证等功能确保每位乘客能够安全访问个人账户信息。

- **车次查询**
提供按日期、出发站和到达站筛选列车班次的服务，帮助旅客快速定位所需行程选项。

- **订单处理**
支持在线支付、座位分配及电子票据生成等一系列交易流程；同时允许已购订单的状态更新（如取消或改签）。

- **后台管理系统**
面向铁路运营方提供维护服务，包括但不限于新增/编辑线路信息、调整票价策略等行政级权限操作。

#### 数据库表结构设计
针对上述业务需求，在关系型数据库中创建相应的实体表格用于保存各类对象实例化后的持久化记录。以下是几个重要的表单概览：

| 表名 | 字段说明 |
|--|
| `users` | 存储用户的个人信息 |
| `trains` | 记录每趟列车的基础属性 |
| `tickets` | 描述具体某张车票详情 |

#### 关键代码片段展示
下面给出一段简单的示例程序用来模拟部分场景下的交互逻辑——即当一名顾客尝试预定指定编号的席位时所经历的过程：

// 假定存在TicketService类负责协调各层之间的调用关系
@Service
public class TicketServiceImpl implements TicketService {

    @Autowired
    private TrainRepository trainRepo;

    @Override
    public boolean bookSeat(String userId, String trainId, int seatNumber) {
        Optional<Train> optTrain = trainRepo.findById(trainId);
        
        if (!optTrain.isPresent()) return false;
        
        Train targetTrain = optTrain.get();
        List<Integer> availableSeats = targetTrain.getAvailableSeats();

        // 判断目标位置是否可售并完成实际下单动作...
        if (availableSeats.contains(seatNumber)) {
            // 更新库存状态
            
            // 创建新订单关联至当前会话中的客户身份...

            return true; // 成功标记
        } else {
            throw new SeatNotAvailableException("Selected seat is not available.");
        }
    }
}
