Locale: Java: jdk1.8

Database: Mysql: mysql5.7

Application server: Tomcat: tomcat8.5.31

Development tools: IDEA or eclipse

Development technology: Springboot+Vue

2. Project introduction

This project is based on Springboot+Vue to develop and implement an English online learning website with front-end and back-end separation. The system is divided into four types of user roles: visitors, students, teachers, and administrators. Visitors can enter the system to view corresponding information and learn anonymously. After registering and logging in, students can view English learning videos online, view relevant study books, online communication forums, take special tests online, view various English sample essays, personal center, etc. The personal center can view their own collection records, special test records, wrong questions This, forum speech records and other related information. Teachers' accounts are assigned by administrators and can publish relevant videos, books, special tests, etc. online. Administrators can perform corresponding management operations on all information, as shown below.

Three, system display

Front-end home page

Learning video

word book learning

online forum

Topic test

English sample essay

Personal Center

Admin management operations

Teacher login

Fourth, the core code display
