项目编号：BS-PT-108

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+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。

三，系统展示

前端首页

学习视频

单词书学习

在线论坛

专题测试

英语范文

个人中心

管理员管理操作

教师登录

四，核心代码展示
