项目介绍

本项目包含管理员、教师、学生三种角色；

用户角色包含以下功能：

修改密码,查看自己的信息,查看自己的成绩,登录界面等功能。

管理员角色包含以下功能：
修改示例,增删改查学生信息,增删改查教师信息,增删改查课程信息,管理员修改密码等功能。

老师角色包含以下功能：
个人信息查看,修改成绩信息,增加成绩信息,管理学生成绩信息等功能。

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；

5.数据库：MySql 5.7版本；

6.是否Maven项目：否；

技术栈

JSP+CSS+JavaScript+jquery+bootstrap+servlet+mysql

使用说明

1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;
若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行；
3. 将项目中dbconfig.properties配置文件中的数据库配置改为自己的配置;
4. 运行项目，输入http://localhost:8080/ 登录
