背景

为学生提供便捷的课程选择方式，并帮助学校进行课程管理和资源调配；主要功能包括：课程展示，自主选课，取消选课，后台录入课程，统计每门课程报名情况，导出数据，用户管理，管理员管理等。

用户角色：查看课程详情（课程大纲、授课方式、考核方式、学分等信息）、在特定的时间窗口内开放选课，用户可以在规定时间内自由选课
管理员角色：发布选修课程信息，包括课程内容、时间安排、教学大纲
后台选课管理：按每门课程进行选课统计，支持名单数据导出 Excel，打印

概要设计

技术运用

前端基于微信小程序平台进行开发
后端基于 Java Springboot 架构开发
数据库： MySQL (8.0+)
