Java项目:教学辅助平台(java+SpringBoot+Mybaits+Vue+elementui+mysql)

源码获取：俺的博客首页 "资源" 里下载！

环境需要
1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS； 
4.数据库：MySql 5.7/8.0版本均可；
5.是否Maven项目：是；

技术栈
后端：SpringBoot+Mybaits
前端：Vue + elementui

使用说明
项目运行：
1. 使用Navicat或者其它工具，在mysql中创建对应sql文件名称的数据库，并导入项目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse导入项目，导入成功后请执行maven clean;maven install命令；
3. 将项目中application.yml配置文件中的数据库配置改为自己的配置;
4. 运行项目，在浏览器中输入地址：
前台地址：http://localhost:8080/springbootrpj39/front/index.html
后台地址：http://localhost:8080/springbootrpj39/admin/dist/index.html
