项目简介

宿舍管理系统，主要功能包括：
信息管理：
学生管理、班级管理、访客管理、损耗管理、宿舍管理、宿舍评分；
系统管理：
用户管理、角色管理、菜单管理；

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.是否Maven项目: 是；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 
6.数据库：MySql 5.7版本；

技术栈

1. 后端：spring+spring mvc+hibernate
2. 前端：easyui+jQuery+JSP

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. 将项目中db-config.properties配置文件中的数据库配置改为自己的配置;

3. 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，配置tomcat，然后运行；

4. 运行项目，输入http://localhost:8080/xxx 登录

5. 管理员用户名：admin 密码：admin
