好的,以下是一个简单的 MVC 会议室管理系统的代码示例:
1. 数据库表结构:
```
CREATE TABLE room (
id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(50) NOT NULL,
capacity INT NOT NULL,
projector BOOLEAN DEFAULT FALSE,
whiteboard BOOLEAN DEFAULT FALSE,
phone BOOLEAN DEFAULT FALSE
);
CREATE TABLE reservation (
id INT PRIMARY KEY AUTO_INCREMENT,
room_id INT NOT NULL,
start_time DATETIME NOT NULL,
end_time DATETIME NOT NULL,
user_name VARCHAR(50) NOT NULL,
user_phone VARCHAR(20) NOT NULL,
create_time DATETIME NOT NULL,
FOREIGN KEY (room_id) REFERENCES room(id)
);
```
2. 实体类:
```java
public class Room {
private int id;
private String name;
private int capacity;
private boolean projector;
private boolean whiteboard;
private boolean phone;
// getter and setter methods
// ...
}
public class Reservation {
private int id;
private int roomId;
private Date startTime;
private Date endTime;
private String userName;
private String userPhone;
private Date createTime;
// getter and setter methods
// ...
}
```
3. 数据访问对象(DAO):
```java
public class RoomDAO {
public List<Room> listRooms() {
// 查询会议室列表
}
public Room getRoom(int id) {
// 根据 ID 查询会议室
}
public void addRoom(Room room) {
// 添加会议室
}
public void updateRoom(Room room) {
// 更新会议室
}
public void deleteRoom(int id) {
// 删除会议室
}
}
public class ReservationDAO {
public List<Reservation> listReservations(int roomId, Date startTime, Date endTime) {
// 查询预定列表
}
public Reservation getReservation(int id) {
// 根据 ID 查询预定
}
public void addReservation(Reservation reservation) {
// 添加预定
}
public void updateReservation(Reservation reservation) {
// 更新预定
}
public void deleteReservation(int id) {
// 删除预定
}
}
```
4. 控制器:
```java
public class RoomController {
private RoomDAO roomDAO = new RoomDAO();
private ReservationDAO reservationDAO = new ReservationDAO();
public void listRooms(HttpServletRequest request, HttpServletResponse response) {
// 查询会议室列表并渲染到视图中
}
public void addRoom(HttpServletRequest request, HttpServletResponse response) {
// 解析表单数据并添加会议室
}
public void updateRoom(HttpServletRequest request, HttpServletResponse response) {
// 解析表单数据并更新会议室
}
public void deleteRoom(HttpServletRequest request, HttpServletResponse response) {
// 根据 ID 删除会议室
}
public void listReservations(HttpServletRequest request, HttpServletResponse response) {
// 解析查询参数并查询预定列表
}
public void addReservation(HttpServletRequest request, HttpServletResponse response) {
// 解析表单数据并添加预定
}
public void updateReservation(HttpServletRequest request, HttpServletResponse response) {
// 解析表单数据并更新预定
}
public void deleteReservation(HttpServletRequest request, HttpServletResponse response) {
// 根据 ID 删除预定
}
}
```
5. 视图:
这里不提供具体的视图代码,可以使用 JSP 或者 Thymeleaf 等模板引擎来渲染视图。
以上是一个简单的 MVC 会议室管理系统的代码示例,实际上,需要根据具体的业务需求进行设计和实现。
