基于 SpringBoot+Vue 的酒店客房管理系统

技术架构

后端技术：Spring Boot

Spring Boot 作为现代 Java 企业级开发的核心框架，以'约定优于配置'的设计哲学重新定义了应用开发模式。核心特性包括零配置启动、嵌入式服务器、生产就绪监控组件以及微服务友好性。开发者可通过 Starter 依赖体系聚焦于业务逻辑实现。

前端技术：Vue.js

Vue.js 以其渐进式框架设计和卓越的开发体验成为现代前端开发的首选解决方案。技术亮点包括响应式数据流、组件化架构、灵活的渐进式设计以及丰富的生态系统。直观的模板语法结合强大的指令系统，让复杂的用户交互变得简洁明了。
