项目介绍

系统的角色：管理员、宿管、学生

管理员管理宿管员，管理学生，修改密码，维护个人信息。

宿管员管理公寓资产，缴费信息，公共场所清理信息，日常事务信息，审核学生床位安排信息。

学生查看公共场所清理信息，日常事务，缴费信息，在线申请床位，查看床位安排。

环境要求

1.运行环境：最好是java jdk1.8,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：Tomcat7.x,8.X,9.x版本均可

4.硬件环境：windows7/8/10 4G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：MySql5.7/8.0等版本均可；

技术栈

运行环境：jdk8 + tomcat9 + mysql5.7 + windows10

服务端技术：SpringBoot + MyBatis + Vue + Bootstrap + jQuery

使用说明

1.使用Navicati或者其它工具，在mysql中创建对应sq文件名称的数据库，并导入项目的sql文件；

2.使用IDEA/Eclipse/MyEclipse导入项目，修改配置，运行项目；

3.将项目中config-propertiesi配置文件中的数据库配置改为自己的配置，然后运行；
