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

宿舍管理系统基于Spring+SpringMVC+Mybatis开发，系统主要功能如下：

学生管理
班级管理
宿舍管理
卫生管理
维修登记
访客管理

二、技术框架

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

三、安装教程

在idea中配置jdk环境
配置maven环境并下载依赖
配置Tomcat8.0
新建数据库，导入数据库文件
在db.properties文件中将数据库账号密码改成自己本地的
启动运行, 管理员账号密码 admin/123456
