实战-完整代码答题系统

一、前言

考驾照的时候，科目一、科目四的系统如何做的，原来如此简单，就是一个简单的答题系统。
不仅让我联想到了，也可以做一个错题本，不仅仅关于数学，也来源于日常生活，经常做错的事、物。不过这些后续完善，目前系统仅仅只有固定功能，增加题目功能也很简单，如果感兴趣，可自行开发，也可联系。

二、开发设计思路

1、部分-效果图

2、表设计

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

3、代码设计

源码gitee分享地址下载：https://gitee.com/fengqile/demo_exam.git
项目使用SpringBoot+bootstrap+layer，MybatisPlus

三、开发扩展

①扩展功能

可以设计新增功能，新增不同考卷-卷宗表exam_paper，题目设计-题目表exam_items

②前后端分离

只需把前端代码拉到vue中，引入相关组件即可。
