项目介绍
酒店管理系统共分为三个角色,客房经理、前台管理员、客户,各个角色的权限各不相同;
客房经理功能包括:登录、注册、前台用户管理、客房管理、优惠活动、查看留言、更换客房、房费续交、订单查看、报修统计、入驻统计、退房等功能;
前台管理员主要功能:
前台管理:包括客房查询、更换客房、房费续交、订单查看、报修统计、入住统计、退房、查看留言;
客户主要功能:
主要查看用户信息:个人信息、优惠活动、客房信息、订单管理、留言等;
环境需要
1.运行环境:最好是java jdk 1.8,我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境:IDEA,Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境:Tomcat 7.x,8.x,9.x版本均可
4.硬件环境:windows 7/8/10 1G内存以上;或者 Mac OS;
5.数据库:MySql 5.7版本;
6.是否Maven项目: 否;查看源码目录中是否包含pom.xml;若包含,则为maven项目,否则为非maven项目
技术栈
1. 后端:Servlet
2. 前端:JSP+bootstrap+jQuery
使用说明
1. 使用Navicat或者其它工具,在mysql中创建对应名称的数据库,并导入项目的sql文件;
2. 使用IDEA/Eclipse/MyEclipse导入项目,Eclipse/MyEclipse导入时,若为maven项目请选择maven;若为maven项目,导入成功后请执行maven clean;maven install命令,然后运行;
3. 将项目中jdbc.properties配置文件中的数据库配置改为自己的配置;
4. 运行项目,输入localhost:8080/SLH 登录 注:tomcat中配置项目路径必须为/SLH,否则会报错;
客房经理用户名密码:admin/admin
前台管理员用户名密码:test/123456
客户用户名密码:jack/123456
