摘 要
随着科学技术的飞速发展和5G时代的到来,信息时代不断的快速更新迭代。我们现在的网络也随之稳定,人们对于网络信息的依赖也越来越大,以及绿色环保意识的不断加强,无纸化的办公条件成为了大势所趋。而我们学校作为培养人才的地方,更应该走在时代的前沿,所以我们完全可以利用现有的成熟技术来实现一个题库管理系统,它既能减轻老师的负担,又能提高学生们的学习效率,提高考试质量,而且从去年的疫情爆发的情况看来,题库管理系统的开发也变得迫在眉睫了
题库管理系统是一种用于管理题目、试卷、学生信息等教育资源的系统。它可以帮助教师或管理员更好地组织、管理、发布和维护题库,同时也能够提供给学生在线做题、自测、刷题等功能。题库管理系统通常由前端展示页面和后端数据管理系统构成,其中前端页面包括登录注册、题目查询、试卷生成、考试界面等,后端数据管理系统则包括题目库管理、试卷管理、成绩管理、学生信息管理等。题库管理系统的应用范围广泛,包括教育机构、培训机构、在线教育平台等,它可以有效提高教学效率和学习效果,为教育事业的发展做出贡献。

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
