项目介绍
本项目分为管理员、教务人员、招生人员、学生等角色；
管理员角色主要功能包括：
系统状态、阶段定义、管理员维护、数据库管理、查看报名信息、我的登录历史、修改密码、退出系统；
教务人员主要功能包括：
系统状态、查看报名信息、准考证号分配、考场分配、录入成绩、我的登录历史、修改密码、退出系统；
招生人员主要功能包括：
系统状态、阶段设置、招考信息设置、查看报名信息、现场确认、学生密码清零、我的登录历史、修改密码、退出系统；
学生角色主要功能包括：
报考须知、我的报名信息、上传照片、报名表打印、准考证打印、成绩与录取查询、我的登录历史、修改密码、退出系统等；
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
1. 后端：Servlet
2. 前端：JSP+JavaScript+CSS
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WebRoot/META-INF/context.xml配置文件中的数据库配置改为自己的配置;
4. 运行项目，学生角色使用http://localhost:8080/bkxt/index.jsp进行登录
学生账号/密码：zjfhit/123456
管理员登录：http://localhost:8080/bkxt/manage.jsp
管理员账号/密码：manager/123456
教务人员账号/密码：jiaowu/123456
