二、前言
开发语言:Java+Python
数据库:MySQL
系统架构:B/S
后端框架:SpringBoot(Spring+SpringMVC+Mybatis)+Django
前端:Vue+HTML+CSS+JavaScript+jQuery
校园失物招领系统是一款基于B/S架构的综合性管理平台,采用Java/Python双语言支持,分别搭配Spring Boot和Django框架实现后端业务逻辑,前端则运用Vue+ElementUI+HTML构建友好交互界面,底层依托MySQL数据库实现数据持久化存储。系统功能模块完善,包括用户管理、物品类别管理、失物招领管理、失物认领管理、寻物信息管理、失物归还管理、交流互动管理、系统管理以及个人中心九大核心功能板块,实现了校园失物招领全流程数字化管理。用户可通过系统发布失物信息、查询招领状态、在线认领物品,管理员则能对物品类别进行维护、审核发布信息、处理认领申请、统计分析数据,同时系统提供交流互动功能促进信息流通,大幅提升校园失物招领效率,解决传统纸质公告板信息分散、时效性差、查询不便等痛点问题,为校园师生提供便捷、高效、透明的失物招领服务体验。
