毕业设计管理系统

1、本系统使用SSM框架

2、有管理员、教师、学生三种角色，管理员使用admin/admin登录，教师使用t_01/6666登录，学生使用142001/111登录

3、管理员有最大权限，可以进行信息管理、教师管理、学生管理、选题管理、公告管理、查看已上传等；

4、教师角色包括个人信息管理、选题管理、进度管理、学生管理、疑问管理、文档管理、成绩管理

5、学生角色包括个人信息管理、课题管理、进度管理、文档管理、提问管理、查看答辩资格、成绩管理

管理员用户：admin 密码：admin

教师用户：t_01 密码：6666

学生用户：142001 密码：111

环境要求

1.JDK配置

首先安装好JDK，我一般使用1.8版本的JDK。

2.安装IDEA
3.MySQL安装
4. IDEA/Eclipse配置Tomcat 8

MySQL一般安装5.7版本的。
