后端开发语言：Java 后端框架：Spring Boot(Spring+SpringMVC+Mybatis) 前端：微信小程序 数据库：MySQL 系统架构：C/S 开发工具：微信小程序开发工具
二.系统内容简介
课堂考勤签到小程序是一款基于微信小程序平台开发的教育管理系统，采用Java作为后端开发语言，结合Spring Boot框架构建了完整的后端服务体系。系统通过Spring+SpringMVC+MyBatis的技术架构，实现了前后端分离的C/S架构模式，后端数据存储采用MySQL数据库，确保了数据的稳定性和可靠性。该系统主要面向高等院校的日常教学管理需求，为教师和学生提供便捷的考勤管理服务。系统具备完整的用户权限管理体系，包含教师管理和学生管理两个核心用户模块，支持课程信息的全生命周期管理，能够处理学生的请假申请流程，实时记录和统计学生的考勤情况。同时系统还集成了成绩信息管理功能，可以将考勤数据与学习成绩相结合，为教师提供个性化的学习建议管理工具，帮助教师更好地了解学生的学习状态。整个系统设计简洁实用，操作便捷，能够有效提升教学管理的效率和准确性。
