4. Hardware environment: Windows 7/8/10 with more than 1G memory; or Mac OS;
5. Maven project: Yes; Check whether the source code directory contains pom.xml; if so, it is a maven project, otherwise it is a non-maven project
6. Database: MySql 5.7 version;

technology stack

1. Backend: SpringBoot+Mybatis

2. Front end: Layui+HTML

Instructions for use

1. Use IDEA/Eclipse/MyEclipse to import the project. When importing from Eclipse/MyEclipse, if it is a maven project, please select maven;

If it is a maven project, after the import is successful, please execute the maven clean;maven install command to download the required jar package;

2. Use Navicat or other tools to create a database with the corresponding name in mysql, and import the sql file of
the project; 3. Change the database configuration in the application.properties configuration file in the project to your own configuration
4. Configure tomcat, and then run Project, enter http://localhost:8088/login.html to log in
5. Teacher account: admin Password: 123456
