JavaWeb项目：springMVC+mysql实现的Java web学生成绩管理系统
此项目为本人的Java大作业。
前台代码；代码已经上传到github上 下载地址? ? Git
一、项目概况
1.1设计内容
　　一款由spring mvc+mysql实现的学生成绩管理系统，系统主要实现的功能有：学生信息管理、成绩信息管理（包括excel的导入导出）、教师信息管理、用户信息管理、角色权限管理、菜单管理等，功能比较完善，此外还配有论文及模块文档，项目完整源码及视频指导运行教程和论文在最下面有获取方式，。
此系统开发期间我们小组不定时地进行用户使用反馈信息收集，根据收集数据不断对系统进行优化、完善。目的是希望从使用者的角度查找系统的缺陷之处，继而使得整个系统的运行、结构更加清晰化、条理化、自动化。

1.2开发工具
　　Eclipse或者Myeclipse，Java，MySQL，Redis，Html，CSS，JS。
二、详细设计
2.1网站结构
