6.是否Maven项目：否；

技术栈

HTML+CSS+JavaScript+java+jsp+servlet+mysql

使用说明

1. 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；
2. 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；
3. 将项目中src/com/hr/dao/Basedao.java配置文件中的数据库配置改为自己的配置;
4. 运行项目，输入http://localhost:8080/login.jsp 登录
