前端：基于Vue.js框架构建用户界面，使用HTML5、CSS3和JavaScript实现页面结构与交互逻辑，通过Vue Router管理路由，Vuex或Pinia维护全局状态。采用Element UI或Vant组件库快速搭建界面，Axios封装HTTP请求实现与后端的数据通信。

后端：基于springboot框架搭建，遵循Controller-Service-Mapper三层架构。Controller层接收前端请求并校验参数，Service层处理核心业务逻辑，Mapper层通过MyBatis或MyBatis-Plus完成数据库操作。使用Spring Security或Shiro结合JWT实现用户认证与权限控制。

数据库：采用MySQL存储持久化数据，Redis缓存热点信息以提升系统性能。

开发工具：使用IDEA开发后端，VSCode或HBuilderX开发前端，Git进行版本管理，Maven和npm分别管理前后端依赖。
