基于SSM的JSP+MYSQL学生信息管理系统
"基于SSM的学生信息管理系统(MySQL版)
包含源程序，数据库脚本。代码和数据库脚本都有详细注释。课题设计仅供参考学习使用，可以在此基础上进行扩展完善。
开发环境：代码已经上传github，下载地址https://github.com/21503882/student-info
Eclipse Java EE,MySQL5.0,JDK1.7,Tomcat 7
涉及技术点：
MVC模式、SpringMVC、Spring、MyBatis、HTML、JavaScript、CSS、JQUERY、单元测试等
程序功能：
1.管理员功能：管理员管理、学生管理、课程管理、成绩管理。
2.学生功能：查看课程、查看成绩。"
