飞机订票系统代码Java完整代码

编写完整的飞机订票系统代码涉及到大量的逻辑和组件，包括用户界面、数据库交互、业务逻辑等。这里我将提供一个简化的概念框架，而不是一个完整的Java代码。真正的航班预订系统会是一个大型的项目，使用Spring Boot、Hibernate等技术栈，并可能包含前端UI（如Angular或Vue）。

// 引入基本包
import java.util.Date;

// 定义航班类
class Flight {
    private String flightNumber;
    private Date departureDate;
    private Date arrivalDate;
    private int availableSeats;

    // getters and setters, constructor, etc.
}

// 定义乘客类
class Passenger {
    private String name;
    private String email;

    // getters and setters, constructor
}

// 定义机票类，包含航班信息和乘客信息
class Booking {
    private Flight flight;
    private Passenger passenger;
    private Date bookingDate;

    // getters and setters, constructor
}

// 飞机订票服务接口
interface TicketBookingService {
    void bookFlight(Booking booking);
    boolean checkAvailability(String flightNumber, Date date);
    // 更多方法...
}

// 实现接口
@Service
public class TicketBookingServiceImpl implements TicketBookingService {
    private FlightRepository flightRepository;
    private PassengerRepository passengerRepository;

    @Autowired
    public TicketBookingServiceImpl(FlightRepository flightRepository, PassengerRepository passengerRepository) {
        this.flightRepository = flightRepository;
        this.passengerRepository = passengerRepository;
    }

    @Override
    public void bookFlight(Booking booking) {
        // 逻辑：验证座位，更新航班和乘客信息，保存预订
    }

    // 其他方法实现...
}

// 数据访问对象 (DAO)
@Repository
public interface FlightRepository extends JpaRepository<Flight, Long> {
    Flight findAvailableFlightByDepartureDate(Date date);
}

// 数据访问对象 (DAO)
@Repository
public interface PassengerRepository extends JpaRepository<Passenger, Long> {
}

// Main入口类
@SpringBootApplication
public class AirTicketBookingApplication {
    public static void main(String[] args) {
        SpringApplication.run(AirTicketBookingApplication.class, args);
    }
}
