注：本文章仅供参考和学习，由于开发时间较短，系统存在一些漏洞和不合理之处，可以下载后自行修改完善。项目导入到eclipse中可能会因为JDK，tomcat版本不一致报错，可以自行新建一个项目将本项目文件粘贴到新项目中即可。如果出现乱码可能是英文编码方式不一致，可以修改一下项目的编码方式，本项目使用的编码方式为UTF-8。
系统开发环境
本系统基于MVC模式开发，系统设计采用了面向对象编程思想，系统开发选择了Eclipse作为集成开发环境，使用了JSP和Java语言编写程序；前端使用HTML+CSS+JavaScript技术设计开发页面；后台数据库使用MySQL5.6.26。该系统所需要的运行环境如下：
1．客户端：360浏览器或者其他常用浏览器；
2．服务器端：安装JVM及MySQL数据库。
系统开发技术
1．MVC模式
2．JSP技术
3．JDBC（Java Data Base Connectivity）技术
系统基本功能简介
本系统基于MVC模式设计和开发的，在MVC模式中，三个层各施其职，所以如果一旦哪一层的需求发生了变化，就只需要更改相应的层中的代码而不会影响到其它层中的代码，有利于实现各施其职，互不干涉。同时由于按层把系统分开，有利于开发人员之间的任务分工。分层后降低了层与层之间的依赖有利于组件的重用和代码的标准化开发。
在功能设计上，系统包含前台和后台两大部分功能，其中前台主要按照用户权限实现用户信息查询查询、修改密码功能、学生信息查询功能、教师信息查询功能、课程信息查询功能、选课信息查询功能和成绩信息查询功能。其中学生可以查询其用户信息，个人信息，课程信息，选课信息和成绩信息。教师可以查询其用户信息，个人信息，学生信息，课程信息，成绩信息和选课信息。同时教师还可以对学生信息和成绩信息进行查询、添加、修改、删除、批量删除等操作。后台主要实现学生信息管理功能，教师信息管理功能，课程信息管理功能，成绩信息管理功能和选课信息管理功能这五大功能模块。管理员可以在学生信息模块、教师信息模块、课程信息模块、选课信息模块和成绩信息模块中进行查询，添加，修改，批量删除等操作。在学生信息管理模块中，管理员可以输入学号查询指定学生信息。在教师信息管理模块中，管理员可以输入教师号查询指定教师信息。在成绩信息管理模块中，管理员可以修改学生成绩并将成绩信息暂存。在课程信息管理模块中，管理员可以以输入课程号查询指定课程信息。在选课信息管理模块中，管理员可以可以以输入教师号或课程号查询指定选课信息。
