博主主页：Java旅途
简介：分享计算机知识、学习路线、系统源码及教程
文末获取源码

一、项目介绍

酒店管理系统基于Spring+SpringMVC+Mybatis开发，功能简单，可用于毕设或者课程设计。

管理员功能如下：

• 房间管理
• 住客入住
• 住客管理
• 会员管理
• 登录、修改密码
• 数据导出

二、技术框架

• 后端：Spring，Springmvc，Mybatis
• 前端：layui

三、安装教程

1. 用idea打开项目
2. 在idea中配置jdk环境
3. 配置maven环境并下载依赖
4. 配置tomcat8.0
5. 新建数据库，导入数据库文件
6. 在jdbc.properties文件中将数据库账号密码改成自己本地的
7. 启动运行, 管理员账号密码 admin/123456

四、运行截图
