项目介绍
本项目包含前后台，分为普通用户与管理员两种角色，前台为普通用户登录，后台为管理员登录；
管理员角色包含以下功能： 登录,会员管理-增删改查,员工管理-增删改查,课程管理,网站新闻管理,新闻添加编辑,留言管理等功能。
用户角色包含以下功能： 查看首页,查看关于我们,查看新闻,课程简介,会员注册,会员登录,查看新闻活动,登录后留言,查看留言等功能。
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
- 后端：Spring+SpringMVC+Mybatis 2. 前端：JSP+CSS+JavaScript+Layui+bootstrap+jquery
使用说明
- 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db.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localhost:8080/ 登录
