项目介绍
管理员管理实验材料,审核教师与学生对实验材料的申请信息,统计每学年实验材料的使用总数信息。
教师申请使用实验材料,查看实验材料的申请信息是否通过审核。
学生申请使用实验材料,查看实验材料的申请信息是否通过审核。
环境要求
1.运行环境:最好是java jdk1.8,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:Tomcat7.x,8.X,9.x版本均可
4.硬件环境:windows7/8/10 4G内存以上;或者Mac OS;
5.是否Maven项目:是;查看源码目录中是否包含pom.xml;若包含,则为maven项目,否则为非maven.项目
6.数据库:MySql5.7/8.0等版本均可;
技术栈
运行环境:jdk8 + tomcat9 + mysql5.7 + windows10
服务端技术:Java、Spring、SpringMVC、Mybatis,SSM
使用说明
1.使用Navicati或者其它工具,在mysql中创建对应sq文件名称的数据库,并导入项目的sql文件;
2.使用IDEA/Eclipse/MyEclipse导入项目,修改配置,运行项目;
3.将项目中config-propertiesi配置文件中的数据库配置改为自己的配置,然后运行;
