SSH整合开发Demo--酒店预订系统

来源：互联网发布：c语言标准库函数 chm 编辑：程序博客网时间：2024/04/28 04:28

酒店预订系统包括4项功能。

管理员管理：系统中设计了管理员管理菜单，在该菜单中可以直接跳转到房间管理、订单管理、客户管理的响应页面，并完成对房间、订单和客户信息的增加、删除和修改。
房间管理：实现按房间号查询指定房间以及添加、删除和修改房间信息的功能。
订单管理：实现按订单号查询、按客户编号及房间号查询指定订单、修改预定订单、取消预定订单等功能。
客户管理：实现客户信息录入、查询、修改以及删除的功能。

Hibernate持久层设计
1.创建持久化类
系统中共包含4个持久化类，分别是Admin、Room、Order和User。其中Admin类用来描述酒店管理员的信息，Room类用来描述酒店中各个房间的信息，Order类用来描述客户预定房间的订单信息，而User类则用来描述客户的信息。

Admin.java类代码如下：

package com.integration.entity;public class Admin {    private int adminid;    private String username;    private String password;    public int getAdminid() {        return adminid;    }    public void setAdminid(int adminid) {        this.adminid = adminid;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }}

Room.java类：

package com.integration.entity;public class Room {    private int roomid;    private String name;    private double price;    private String category;    private int status;    public int getStatus() {        return status;    }    public void setStatus(int status) {        this.status = status;    }    public int getRoomid() {        return roomid;    }    public void setRoomid(int roomid) {        this.roomid = roomid;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public double getPrice() {        return price;    }    public void setPrice(double price) {        this.price = price;    }    public String getCategory() {        return category;    }    public void setCategory(String category) {        this.category = category;    }}

Order.java类：

package com.integration.entity;public class Order {    private int orderid;    private int roomid;    private int userid;    public int getOrderid() {        return orderid;    }    public void setOrderid(int orderid) {        this.orderid = orderid;    }    public int getRoomid() {        return roomid;    }    public void setRoomid(int roomid) {        this.roomid = roomid;    }    public int getUserid() {        return userid;    }    public void setUserid(int userid) {        this.userid = userid;    }}

User.java类：

package com.integration.entity;public class User {    private int userid;    private String username;    private String password;    private String mobile;    private String email;    public int getUserid() {        return userid;    }    public void setUserid(int userid) {        this.userid = userid;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    public String getMobile() {        return mobile;    }    public void setMobile(String mobile) {        this.mobile = mobile;    }    public String getEmail() {        return email;    }    public void setEmail(String email) {        this.email = email;    }}

2.创建映射文件
持久化类创建完成之后，下面编写映射文件，系统一共有Order.hbm.xml、Admin.hbm.xml、Room.hbm.xml以及User.hbm.xml这4个映射文件。

Order.hbm.xml映射文件：

<?xml version="1.0"?><!DOCTYPE hibernate-mappingPUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping>    <class name="com.integration.entity.Order" table="h_order">        <id name="orderid" column="orderid" type="int">            <generator class="identity"> <!-- 主键id的生成方式为自增 -->            </generator>        </id>        <property name="userid" column="userid" type="int"></property>        <property name="roomid" column="roomid" type="int"></property>    </class></hibernate-mapping>

Admin.hbm.xml映射文件：

<?xml version="1.0"?><!DOCTYPE hibernate-mappingPUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping>    <class name="com.integration.entity.Admin" table="admin">        <id name="adminid" column="adminid" type="int">            <generator class="identity"> <!-- 主键id的生成方式为自增 -->            </generator>        </id>        <property name="username" column="username" type="string"></property>        <property name="password" column="password" type="string"></property>    </class></hibernate-mapping>

Room.hbm.xml映射文件：

<?xml version="1.0"?><!DOCTYPE hibernate-mappingPUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping>    <class name="com.integration.entity.Room" table="room">        <id name="roomid" column="roomid" type="int">            <generator class="identity"> <!-- 主键id的生成方式为自增 -->            </generator>        </id>        <property name="name" column="name" type="string"></property>        <property name="price" column="price" type="double"></property>        <property name="category" column="category" type="string"></property>        <property name="status" column="status" type="int"></property>    </class></hibernate-mapping>

User.hbm.xml映射文件：

<?xml version="1.0"?><!DOCTYPE hibernate-mappingPUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping>    <class name="com.integration.entity.User" table="user">        <id name="userid" column="userid" type="int">            <generator class="identity"> <!-- 主键id的生成方式为自增 -->            </generator>        </id>        <property name="username" column="username" type="string"></property>        <property name="password" column="password" type="string"></property>        <property name="mobile" column="mobile" type="string"></property>        <property name="email" column="email" type="string"></property>    </class></hibernate-mapping>

暂时先写到这里，吃完饭继续……
