Java项目:学生选课管理系统(java+SpringBoot+Mybatis-plus+Thymeleaf+mysql)
源码获取：博客首页 "资源" 里下载！
系统主要有以下功能：选课管理、教评管理、班级管理、年级管理、专业管理、系部管理、教师授课管理、录入教师、学生管理、学生选课管理、退学管理、退选管理、课目管理、成绩管理、新闻管理、系统管理等
主要有三个角色： 管理员、学生、教师。
管理员后台账号：admin 密码：123456
学生账号：student表 密码是身份后6位 （教师同样）
运行环境：windows/Linux均可、jdk1.8、mysql5.7、idea/eclipse均可。
