一,环境介绍
语言环境:Java: jdk1.8
数据库:Mysql: mysql5.7
应用服务器:Tomcat: tomcat8.5.31
开发工具:IDEA或eclipse
开发技术:Springboot+Vue
二,项目简介
本项目基于Springboot和Vue开发实现一个前后端分离的英语在线学习网站。系统分为四类用户角色:游客、学生、教师、管理员。游客进入系统可以进行相应信息查看和不记名学习。学生注册登录后可以在线查看英语学习视频、查看相关学习用书、在线交流论坛、在线进行专项测试、查看各类英语范文、个人中心等,个人中心可以查看自己的收藏记录、专题测试记录、错题本、论坛发言记录等相关信息。老师的账户由管理员分配,可以在线发布相关视频、书籍、专题测试等。管理员可以对所有的信息进行相应的管理操作,具体看下面展示。
