二.系统内容简介
本高校班务管理小程序是基于Spring Boot框架和微信小程序技术开发的教学辅助管理系统，采用Java语言构建后端服务，结合MySQL数据库实现数据持久化存储。系统涵盖了高校日常班级管理的核心业务流程，包括教师与学生信息管理、专业年级班级的组织架构管理、课程信息与课表的统筹安排、考勤签到与请假审批的流程化处理、作业布置提交及成绩评定的全流程跟踪、考试成绩的统计分析以及班务通知的及时发布等功能模块。通过C/S架构设计，系统实现了教师端的管理操作与学生端的互动参与，为高校班级日常事务处理提供了数字化解决方案，有效提升了班级管理效率，简化了传统纸质化办公流程，为师生提供了便捷的移动端操作体验。
