一.开发工具简介
开发语言：Java+Python（两个版本都支持） 后端框架：Spring Boot(Spring+SpringMVC+Mybatis)+Django（两个版本都支持） 前端：Vue+ElementUI+HTML 数据库：MySQL 系统架构：B/S 开发工具：IDEA（Java的）或者PyCharm（Python的）
二.系统内容简介
乡村支教管理系统是一个基于Spring Boot和Vue技术栈开发的B/S架构管理平台，旨在为乡村支教活动提供全方位的数字化管理支持。系统采用前后端分离的设计模式，后端运用Spring+SpringMVC+Mybatis框架处理业务逻辑，前端通过Vue框架实现交互界面，数据存储依托MySQL数据库。系统涵盖志愿者信息管理、乡村学校档案维护、支教项目发布与报名、任务分配与提交跟踪、教学资源共享分配、支教活动组织、评价反馈收集、奖励机制实施、论坛交流互动等多个功能模块，构建了从志愿者招募、项目匹配、任务执行到成果评估的完整业务流程。通过知识库模块沉淀支教经验，借助资源管理模块优化教学物资配置，利用社交论坛促进志愿者之间的经验分享，配合公告系统及时传达重要信息，形成一套相对完善的乡村支教组织与管理解决方案，为支教工作的规范化开展提供技术支撑。
