编写代码电影票务管理系统基于SSM框架实现座位管理

这里给出一个简单的电影票务管理系统的座位管理实现代码，基于SSM框架:

1. Seat.java

public class Seat {
    private int id;
    private int row;
    private int col;
    private boolean isAvailable;
    
    // getter 和 setter 方法
}

2. SeatMapper.java

public interface SeatMapper {
    public List<Seat> getSeatsByHall(int hallId);
    public void updateSeat(Seat seat);
}

3. SeatMapper.xml

<mapper namespace="com.example.mapper.SeatMapper">
    <resultMap id="seatResultMap" type="com.example.model.Seat">
        <id column="id" jdbcType="INTEGER" property="id"/>
        <result column="row" jdbcType="INTEGER" property="row"/>
        <result column="col" jdbcType="INTEGER" property="col"/>
        <result column="is_available" jdbcType="BOOLEAN" property="isAvailable"/>
    </resultMap>

    <select id="getSeatsByHall" resultMap="seatResultMap">
        select * from seat where hall_id = #{hallId}
    </select>

    <update id="updateSeat">
        update seat set is_available = #{isAvailable} where id = #{id}
    </update>
</mapper>

4. SeatService.java

@Service
public class SeatService {
    @Autowired
    private SeatMapper seatMapper;

    public List<Seat> getSeatsByHall(int hallId) {
        return seatMapper.getSeatsByHall(hallId);
    }

    public void updateSeat(Seat seat) {
        seatMapper.updateSeat(seat);
    }
}

5. SeatController.java

@Controller
@RequestMapping("/seat")
public class SeatController {
    @Autowired
    private SeatService seatService;

    @GetMapping("/getSeatsByHall")
    @ResponseBody
    public List<Seat> getSeatsByHall(int hallId) {
        return seatService.getSeatsByHall(hallId);
    }

    @PostMapping("/updateSeat")
    @ResponseBody
    public void updateSeat(@RequestBody Seat seat) {
        seatService.updateSeat(seat);
    }
}

6. seat.jsp

<table>
    <tbody>
        <c:forEach items="${seats}" var="seat">
            <tr>
                <td>${seat.row}</td>
                <td>${seat.col}</td>
                <td>
                    <c:if test="${seat.isAvailable}">
                        <button onclick="updateSeat(${seat.id}, false)">选座</button>
                    </c:if>
                    <c:if test="${!seat.isAvailable}">
                        <button onclick="updateSeat(${seat.id}, true)">取消选择</button>
                    </c:if>
                </td>
            </tr>
        </c:forEach>
    </tbody>
</table>

<script>
function updateSeat(id, isAvailable) {
    $.ajax({
        url: "/seat/updateSeat",
        type: "POST",
        contentType: "application/json",
        data: JSON.stringify({
            id: id,
            isAvailable: isAvailable
        })
    }).done(function() {
        location.reload();
    });
}
</script>

上述代码实现了一个简单的座位管理功能，包括获取某个影厅的所有座位信息，以及选择和取消选择座位的操作。具体实现过程中，可以根据自己的实际需求进行调整和优化。
