ssm自习室座位预约管理java源代码

当然，我可以为您提供一个简单的SSM自习室座位预约管理的Java源代码示例。请注意，这只是一个基本的示例，实际应用中可能需要根据具体需求进行修改和完善。

首先，我们需要创建一个座位实体类 Seat.java：

public class Seat {
    private int id;
    private String name;
    private boolean isAvailable;

    // 省略构造方法和getter/setter方法
}

接下来，创建一个座位预约管理的接口 SeatReserveMapper.java：

public interface SeatReserveMapper {
    List<Seat> getAllSeats();

    Seat getSeatById(int id);

    void updateSeatAvailability(Seat seat);
}

然后，我们创建座位预约管理的DAO实现类 SeatReserveMapperImpl.java，并使用MyBatis框架进行数据库操作：

@Repository
public class SeatReserveMapperImpl implements SeatReserveMapper {
    @Autowired
    private SqlSession sqlSession;

    @Override
    public List<Seat> getAllSeats() {
        return sqlSession.selectList("getAllSeats");
    }

    @Override
    public Seat getSeatById(int id) {
        return sqlSession.selectOne("getSeatById", id);
    }

    @Override
    public void updateSeatAvailability(Seat seat) {
        sqlSession.update("updateSeatAvailability", seat);
    }
}

接下来，我们可以创建一个座位预约服务的接口 SeatReservationService.java：

public interface SeatReservationService {
    List<Seat> getAllSeats();

    Seat getSeatById(int id);

    boolean reserveSeat(int id);

    boolean cancelReservation(int id);
}

然后，创建座位预约服务的实现类 SeatReservationServiceImpl.java，并注入 SeatReserveMapper：

@Service
public class SeatReservationServiceImpl implements SeatReservationService {
    @Autowired
    private SeatReserveMapper seatReserveMapper;

    @Override
    public List<Seat> getAllSeats() {
        return seatReserveMapper.getAllSeats();
    }

    @Override
    public Seat getSeatById(int id) {
        return seatReserveMapper.getSeatById(id);
    }

    @Override
    public boolean reserveSeat(int id) {
        Seat seat = seatReserveMapper.getSeatById(id);
        if (seat != null && seat.isAvailable()) {
            seat.setAvailable(false);
            seatReserveMapper.updateSeatAvailability(seat);
            return true;
        }
        return false;
    }

    @Override
    public boolean cancelReservation(int id) {
        Seat seat = seatReserveMapper.getSeatById(id);
        if (seat != null && !seat.isAvailable()) {
            seat.setAvailable(true);
            seatReserveMapper.updateSeatAvailability(seat);
            return true;
        }
        return false;
    }
}

最后，您可以创建一个用于测试的主类 Main.java：

public class Main {
    public static void main(String[] args) {
        // 初始化Spring容器
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        // 获取座位预约服务实例
        SeatReservationService seatReservationService = (SeatReservationService) context.getBean("seatReservationServiceImpl");

        // 获取所有座位信息
        List<Seat> seats = seatReservationService.getAllSeats();
        for (Seat seat : seats) {
            System.out.println("座位ID：" + seat.getId() + "，名称：" + seat.getName() + "，是否可用：" + seat.isAvailable());
        }

        // 预约座位
        int seatId = 1;
        boolean reservationResult = seatReservationService.reserveSeat(seatId);
        if (reservationResult) {
            System.out.println("预约成功！");
        } else {
            System.out.println("预约失败！");
        }

        // 取消预约
        int cancelSeatId = 1;
        boolean cancelResult = seatReservationService.cancelReservation(cancelSeatId);
        if (cancelResult) {
            System.out.println("取消预约成功！");
        } else {
            System.out.println("取消预约失败！");
        }
    }
}

这就是一个简单的SSM自习室座位预约管理的Java源代码示例。请注意，在实际开发中，您可能还需要配置数据库连接、编写SQL语句等。此外，为了使代码能够正常运行，您还需要引入相应的依赖，例如Spring、MyBatis等。
