毕业设计：基于Web实现多用户宿舍管理系统
项目编号：BS-GX-033
开发技术：
后台：jsp+servlet+jdbc
前台：jsp+bootstrap
运行环境：
数据库：mysql5.7
JDK: 1.8
Maven: 3.9
开发工具：IDEA /Eclipse
本系统基于jsp实现了一个宿舍管理系统，功能完整，界面美观大方，交互简洁方便，比较适合做毕业设计使用。主要分为三个角色用户：管理员，宿舍管理员，学生
系统管理员：用户管理、宿舍楼管理、楼管管理、缺勤管理。
宿舍管理员主要包括：
缺勤管理、学生管理
学生主要包括：缺勤查看
系统 主要实现功能界面展示如下：
管理员登陆
学生管理
宿舍楼管理
缺勤管理
宿舍管理员登陆
缺勤管理
学生登陆系统
核心实现代码如下：
