Java畢業(yè)設計之多用戶宿舍管理系統(tǒng)的實現(xiàn)
更新時間：2022年02月22日 08:47:40 作者：編程指南針
這篇文章主要介紹了基于Java實現(xiàn)的多用戶宿舍管理系統(tǒng)，本文采用了jsp、servlet、jdbc等技術，文中示例代碼講解詳細，需要的可以參考一下
介紹
項目編號：BS-GX-033
開發(fā)技術
后臺：jsp+servlet+jdbc
前臺：jsp+bootstrap
運行環(huán)境
數(shù)據(jù)庫：mysql5.7
JDK: 1.8
Maven: 3.9
開發(fā)工具
IDEA /Eclipse
本系統(tǒng)基于jsp實現(xiàn)了一個宿舍管理系統(tǒng)，功能完整，界面美觀大方，交互簡潔方便，比較適合做畢業(yè)設計使用。主要分為三個角色用戶：管理員，宿舍管理員，學生
功能介紹
系統(tǒng)管理員：用戶管理、宿舍樓管理、樓管管理、缺勤管理。
宿舍管理員主要包括：
缺勤管理、學生管理
學生主要包括：缺勤查看
效果圖
系統(tǒng)主要實現(xiàn)功能界面展示如下：
管理員登陸
學生管理
宿舍樓管理
缺勤管理
宿舍管理員登陸
缺勤管理
學生登陸系統(tǒng)
核心代碼
核心實現(xiàn)代碼如下：
