java servlet 学生管理系统myeclipse开发oracle数据库BS模式java编程网

一、源码特点
?? ?java servlet 学生管理系统是一套完善的web设计系统，对理解JSP java编程开发语言有帮助servlet+bean+dao (mvc模式开发)，系统具有完整的源代码和数据库，开发环境为
TOMCAT7.0,Myeclipse8.5开发，数据库为Oracle 10g，使用java语言开发系统主要采用B/S模式开发。

二、功能介绍
(1)学生管理：对学生信息进行添加、删除、修改和查看
(2)教师管理：对教师信息进行添加、删除、修改和查看
(3)管理员管理：对管理员信息进行添加、删除、修改和查看
(4)课程管理：对课程信息进行添加、删除、修改和查看
(5)选课管理：对选课信息进行添加、删除、修改和查看
(6)成绩管理：对成绩信息进行添加、删除、修改和查看
(7)学分预警管理：对学分预警信息进行添加、删除、修改和查看
(8)用户登录、身份验证，不同的权限，不同的菜单

三、注意事项
?? ?1、管理员账号：admin密码：admin 数据库配置文件DBO.java
?? ? 2、开发环境为TOMCAT7.0,Myeclipse8.5开发，数据库为Oracle 10g，使用java语言开发。
?? ?3、数据库文件名是re data.sql re table.sql ，系统名称stu
?? ?4、系统首页地址：http://127.0.0.1:8080/stu/login.jsp
