一、个人简介
💖💖作者：计算机编程果茶熊 💙💙个人简介：曾长期从事计算机专业培训教学，担任过编程老师，同时本人也热爱上课教学，擅长Java、微信小程序、Python、Golang、安卓Android等多个IT方向。会做一些项目定制化开发、代码讲解、答辩教学、文档编写、也懂一些降重方面的技巧。平常喜欢分享一些自己开发中遇到的问题的解决办法，也喜欢交流技术，大家有技术代码这一块的问题可以问我！ 💛💛想说的话：感谢大家的关注与支持！ 💜💜 网站实战项目 安卓/小程序实战项目 大数据实战项目 计算机毕业设计选题 💕💕文末获取源码联系计算机编程果茶熊
二、系统介绍
开发语言：Java+Python 数据库：MySQL 系统架构：B/S 后端框架：SpringBoot(Spring+SpringMVC+Mybatis)+Django 前端：Vue+HTML+CSS+JavaScript+jQuery
JavaWeb精品课程网站是一个基于SpringBoot框架和Vue+ElementUI技术栈开发的综合性在线教育管理平台。该系统采用前后端分离的B/S架构设计，后端使用SpringBoot+SpringMVC+MyBatis技术栈，前端采用Vue.js框架结合ElementUI组件库构建用户界面，数据存储采用MySQL数据库。系统功能涵盖教师管理、学生管理、课程信息管理、课程分类管理、课程成绩管理、班级管理、选择课程管理、发布作业管理、完成作业管理、考试成绩管理、学习资料管理、资料分类管理、论坛分类管理、留言板管理等17个核心功能模块。系统支持教师发布课程内容、布置作业任务，学生在线选课学习、提交作业、参与讨论，管理员进行系统维护和数据管理等多角色操作。通过Vue组件化开发和ElementUI美观界面设计，为用户提供良好的交互体验，同时SpringBoot的快速开发特性和MyBatis的数据持久化能力确保系统的稳定性和可扩展性。
