基于Java SSM框架實(shí)現(xiàn)簡易的評教系統(tǒng)
更新時(shí)間：2022年02月07日 09:25:11 作者：編程指南針
這篇文章主要介紹了通過Java SSM框架實(shí)現(xiàn)一個(gè)簡易的評教系統(tǒng)的示例代碼，文中的代碼講解詳細(xì)，感興趣的小伙伴可以了解一下
介紹
項(xiàng)目編號：BS-GX-014
數(shù)據(jù)庫：mysql
開發(fā)工具：IDEA / ECLIPSE
開發(fā)技術(shù)：SSM 框架
本系統(tǒng)基于SSM框架實(shí)現(xiàn)。主要包含三個(gè)角色，管理員，老師，學(xué)生。管理員主要管理學(xué)生，老師，課程。學(xué)生可以進(jìn)行選課，選完課后可以對任課老師評價(jià)。老師可以查看自己的評價(jià)信息。
效果圖
部分展示功能如下：
管理員角色：
學(xué)生角色：
老師角色：
