基于SSM实现在校学生考试系统

项目编号：BS-GX-018

本系统基于SSM框架实现开发，前端采用BootStrap+Jquery 实现页面的设计与用户的交互。开发工具使用IDEA或Eclipse,数据库采用MYSQL数据库。

在校学生考试系统是一个功能非常完整的系统，界面简洁大方，用户交互性好，完整的包含了在校学生考试需要的相关功能：像题库管理，试卷管理，组卷管理，考试安排管理，在线考试，自动阅卷等功能均包含在内，比较适合做毕业设计使用，如果你选择了它，一定是一个优秀的毕业设计。

本系统角色分为三种：

管理员：可以对各类信息进行管理操作等

教师：主要进行试卷管理，试题管理和安排考试等

学生：主要进行系统参加考试，并进看考试分析结果等

下面一一为大家展示系统的相关功能。

管理员登陆

http://localhost:8080/admin/login.jsp pcs / 123123

后台管理主界面：

年级管理

科目管理

班级管理：基本信息管理

班级管理：各班人数统计

教师管理：

学生管理：基本信息管理

学生管理：学生考试信息管理

试卷管理：

试题管理：

导入试题：

考试安排：

考试记录：

二，教师登陆系统

lyinping / 123456

考试登陆系统后一些基本信息只能查看，不能管理，但是可以管理学生、试卷、试题、安排考试，具体功能见管理员操作，不再一一截图。

三，学生登陆系统

user01 / 111111

学生在前台先注册再登陆：

进入考试中心进行考试：

答题考试

考试历史：回顾试卷

以上是在校学生考试系统的部分功能展示，所展示的各个功能模块增删改查的功能均能正常运行，功能十分强大，业务非常流畅，是一个难得的优秀系统。
