如何使用SSM+JSP实现一个教务管理系统-阿里云开发者社区

最近为客户开发了一套学校用教务管理系统，主要实现学生、课程、老师、选课等相关的信息化管理功能，今天拿出来给大家介绍一下：

系统编号：BS-GX-020

后台技术：Spring+Springmvvc+mybatis+shiro

前端技术：Bootstrap+jquery+ajax

页面开发：JSP

开发工具：IDEA 或 Eclipse

数据库：mysql5

应用服务器：tomcat8

JAVA版本：jdk1.8

说明：本系统基于SSM框架开发而成，系统功能完整，界面简洁大方，运行无误，适合做毕业设计使用。

系统分三个角色：

1,管理员角色：可以管理课程，管理教师，管理学生，个人信息管理等

2,教师角色：可以管理选课成绩，对选修本人的课程进行打分，个人信息管理等

3,学生角色：可以进行选课，退课，查看选课信息，选课成绩，个人信息管理等

系统功能演示如下：

管理员登陆：

课程管理：

添加课程：分配老师

学生管理：

老师管理：

重置其它账户密码：

密码修改：

教师登陆：

为选课的学生打分

学生登陆：

己选课程：显示己选未结课（未打分）

己修课程：显示己选并结课（己打分）

以上是基于SSM教务管理系统的部分功能展示，本项目比较适合JAVA语言方面的毕业设计系统使用。
