[Java毕设项目01]基于SpringBoot开发的教务管理系统

来源：华佗小知识

1、系统技术栈

  • 后端：Springboot、MyBatis、SpringMVC

  • 前端：html、css、JavaScript、bootstrap、Vue.js

  • JDK版本：1.8

  • 数据库：MySQL 5.7

  • 前后端：不分离

  • 编辑器：IDEA 2022

 2、数据表的设计（只展示管理员、教师、学生的表设计）

管理员信息表

教师信息表

学生信息表

3、 系统界面实现以及部分后台代码实现

  • 登录模块

    ✥界面

    @RestController
@RequestMapping
public class AccountController
