一、前言
项目介绍
采用springboot spring mybatis thyeleaf实现的在线学习系统，一共2个身份。
管理员登录系统后可以管理所有用户信息，管理角色信息，添加修改管理课件信息，学生学习培训批次管理，成绩导入管理
学生登录系统后可以查询自己的个人信息，查询课件列表学习，查询我的培训记录，查询自己的成绩
采用springboot框架实现 前台模板用的thymeleaf 数据库层采用mybatis框架 注解模式
upload文件夹放入d盘根目录！
项目运行
登录地址： http://localhost:8080/th/login
管理员账号和密码： admin admin
学生登录账号： 1314 密码： 123456
