Java连接MySQL实现宿舍管理系统

2021/6/24 21:03:17   来源:

功能概述

管理员功能:
1)宿舍床位管理,包括:宿舍楼编号、房间编号,床位号、在住人等。
2)学生入住,包括学生信息录入,床位分配等。
3)邮件信息录入。
4)夜归学生录入
5)宿舍报修信息管理
6)学生离校,宿舍床位清空,床位调整。
学生功能
1)邮件查询
2)宿舍故障报修
另外根据实际情景,这里也实现了一些较为复杂的功能如下:
1)宿舍管理员在添加夜归生信息后,系统能够在该夜归生登录学生端时立即收到夜归信息警告并显示其姓名和夜归次数,另外系统只会提醒一次。
2)增加了报修处理反馈,学生在提交报修处理后,宿舍管理员会立即收到并做出响应。
3)增加了文件PDF输出功能
4)能够实现宿舍、床位分配或调整时,直接安排空余位置,不能重复。
5)设计了一个较为美观的界面并能够将信息以表单形式展示。
6)提供了验证码注册登录服务


开发环境

Eclipse 2019 jdk1.8
需要导入下面两个jar包(版本可能不一样,与自己版本对应即可,我电脑用的是这两个):
