JavaWeb教师信息管理系统java+mysql+ssm
上周周末断网。。。。。无聊的时候写的demo，SSH的。
SIMS(Student Information Management System，教师信息管理系统) 包括登录、教师信息录入，修改，删除，查询，数据批量导出等等功能。
开发环境：Eclipse ,jdk1.8
框架：SpringMvc+Hibernate(ORM工具)
前台：JSP
数据库：MySQL
众所周知，Spring配置是相当头疼的，后面尽量用Springboot写一下(当然得先学，省去自己配制还是相当方便的)。本来想把项目源码放到Github上面，
但是还要自己配置，就懒得放了。。。
话不多说，先看下目录结构：
java+mysql+ssm教师信息管理系统
整个项目开发周期2周，为学校做的一个独立的系统；兼容在原来学校的教务系统里面
代码已经上传github，下载地址： https://github.com/21503882/teacher
