基于java+ssm+vue+mysql的毕业设计管理系统

项目介绍

21世纪的今天,随着社会的不断发展与进步,人们对于信息科学化的认识,已由低层次向高层次发展,由原来的感性认识向理性认识提高,管理工作的重要性已逐渐被人们所认识,科学化的管理,使信息存储达到准确、快速、完善,并能提高工作管理效率,促进其发展。

论文主要是对毕业设计管理系统,进行了介绍,包括研究的现状,还有涉及的开发背景,然后还对系统的设计目标进行了论述,还有系统的需求,以及整个的设计方案,对系统的设计以及实现,也都论述的比较细致,最后对毕业设计管理系统 进行了一些具体测试。

开发环境

开发语言:Java 数据库 :MySQL 系统架构:B/S 后端框架:SSM 前端框架:Vue 开发工具:IDEA或者Eclipse,JDK1.8,Maven 支持定做:Java/PHP/Python/Android/小程序/Vue/爬虫/C#/Asp.net
