系统说明

该项目采用技术jsp、SpringMVC、Spring、Mybatis、tomcat服务器、mysql数据库本次介绍的系统采用的是Jsp+MySQL+SSM框架进行开发，Windows 操作系统，前端采用EasyUI框架，采用MyBatis与后台数据库进行连接，MyBatis是SSM中的M，是对Jdbc的封装，完成数据的添加、修改、删除、查询等功能。SSM框架是一个常用的Web项目框架，功能强大而且稳定，而MySQL灵活易维护在开发方面具有方便快捷、使用灵活的特点，以及目前的广泛实际应用，因此使用Jsp、SSM、MySQL来完成该系统整体开发，从而说明本系统在技术方面可行。

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.tomcat环境：Tomcat 7.x,8.x,9.x版本均可4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；5.数据库：MySql 5.7版本；6.是否Maven项目：否；

技术栈

后端：Spring+SpringMVC+Mybatis前端：JSP+CSS+JavaScript+jQuery使用说明

使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行；将项目中springmvc-servlet.xml配置文件中的数据库配置改为自己的配置;运行项目，在浏览器中输入http://localhost:8080/ 登录运行截图
