项目介绍

由SpringMVC+MyBatis为主要框架，mysql8.0配置主从复制实现读写分离。前端主要由bootstrap完成，背景用particles.js插件。数据库交互查询用到pagehelper分页。在添加修改相关功能时通过ajax来验证其主键是否存在可用。代码层次清晰，输入框约束较高，已配置登录拦截。

项目主要分为管理员、教师、学生三种角色；

管理员角色包含以下功能：

管理员登录,学生管理,教师管理,课程管理等功能。

教师角色包含以下功能：
登录界面,查看课程,建立课程计划,管理教学课程,成绩查询结课等功能。

学生角色包含以下功能：

登录界面,选课,确认选课,查看选课结果,退选界面,查看已修课程,管理个人信息等功能。

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：是；

技术栈

1. 后端：Spring+SpringMVC+Mybatis

2. 前端：JavaScript、jQuery、bootstrap4、particles.js、ajax

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applicationContext.xml配置文件中的数据库配置改为自己的配置;注：因为此处为读写分离的，需要配置2处；
4. 运行项目，输入localhost:8080/ 登录
管理员账号/密码：admin/admin
