功能说明

基于javaweb的SpringBoot学生毕业离校系统(java+springboot+mybatis+vue+elementui+mysql)

项目介绍

基于Springboot Vue学生毕业离校系统

角色：管理员、学生、教师三种角色，分为前后台；

学生：学生通过学生登录页面可以填写用户名和密码等信息进行登录操作，登录成功后，进入首页可以查看个人中心、离校流程、网站公告、留言反馈模块等功能模块，进行相对应操作

教师：教师登录后，进入后台系统页面可以查看个人中心、学生管理、离校流程管理、费用结算管理、论文审核管理等功能模块，进行相对应操作

管理员：管理员登录成功后进入到系统操作界面，可以对个人中心、学生管理、教师管理、离校流程管理、费用结算管理、论文审核管理、留言板管理、管理员管理、系统管理等功能模块进行相对应操作。

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+Layui+HTML+CSS+JS

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/springbootb3dn9/front/index.html

学生：学生1/123456

教师：教师1/123456

后台地址：http://localhost:8080/springbootb3dn9/admin/dist/index.html#/login

管理员：abo/abo
