基于ssm的java web简单学生信息管理系统
基于SSM的学生信息管理系统java学生信息管理系统java系统mysql数据库课设毕设
1.包含源程序，数据库脚本。代码和数据库脚本都有详细注释。
2.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：
Eclipse ,MYSQL,JDK1.8,Tomcat 7
涉及技术点：
MVC模式、SpringMvc、Mybatis、Spring、HTML、JavaScript、CSS、JQUERY、DWR、Ajax等
系统采用Mybatis框架实现ORM对象关系映射，前台JSP实现，后台springMvc映射，使用Spring框架进行整合。适合学习J2EE的一段时间的熟手，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1.8. 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，或者你有更好的建议等等都可以的，也可以找我和我一起交流沟通，互相学习进步！但是dai。ma。you。chang
