[Java知识库]SSM教务管理系统

简介

这个项目是一个简单的教务查询系统，该练手小项目希望能帮助到大家，熟悉SSM的整合开发，带全套源码100%可运行，有演示视频。

使用技术

IOC容器：Spring

Web框架：SpringMVC ORM框架：Mybatis 安全框架：Shiro

数据源：C3P0 日志：log4j

前端框架：Bootstrap

开发工具：可以使用eclipse，myeclipse，idea，都可以

数据库：建议mysql5.7，使用mysql8也可以，但要修改驱动类名

用户登录界面

管理员模块-学生管理

管理员模块-课程管理

教师管理

管理员特权-修改其他用户密码

所有用户通用-修改自己密码

老师工作界面

学生查看课程

学生自己的课程

学生已经修完的课程
