1、项目介绍
学生毕业离校系统的开发过程中,采用B / S架构,主要使用Java技术进行开发,结合最新流行的springboot框架。中间件服务器是Tomcat服务器,使用Mysql数据库。该学生毕业离校系统包括管理员、学生和教师。其主要功能包括管理员:首页、个人中心、学生管理、教师管理、离校信息管理、费用结算管理、论文审核管理、管理员管理、留言板管理、系统管理等,前台首页;首页、离校信息、网站公告、留言反馈、个人中心、后台管理等,学生:首页、个人中心、费用结算管理、论文审核管理、我的收藏管理、等,教师:首页、个人中心、学生管理、离校信息管理、费用结算管理、论文审核管理等功能。
2、技术架构
编程语言:Java
前端框架:Vue+LayUI+html,后台前端源码有vue打包生成,并不是前后端分离,当然后台前端有Vue的原始代码,能独立运行
后端框框:SpringBoot
数据库:MySQL
Maven项目:是
运行环境:JDK8+MySQL5.6+Maven3.6+idea+Node.js 14.16
3、演示视频
java基于springboot的学生毕业离校系统管理系统、高校学生离校管理系统,附源码+数据库+文档+PPT,适合毕业设计、课程设计
