java servlet +jsp+mysql Ajax +easyui+jQuery整合开发学生成绩管理系统
"基于JSP的学生成绩管理系统
系统没用任何框架，前台纯JSP实现，后台servlet映射，适合刚学习J2EE的新手，代码思路清晰，注解详细，数据库用的是mysql5.1，服务器用的tomcat7，JDK版本1.7. 编程软件Eclispe J2EE版本。是典型MVC架构，并且前后台分离，
具体功能这里不再赘述，请下方看系统详细演示图，如果大家有什么疑问或者什么不懂得可以在下方给我留言，也可以私信我和我一起交流沟通，互相学习进步代码已经上传github，下载地址 https://github.com/21503882/
