1、项目介绍及开发技术

1.1 项目介绍

现代社会，美食不仅是满足人们基本生存需求的方式，更是一种文化和生活方式的体现。随着互联网技术的发展，人们获取美食信息的途径日益多样化，但信息的碎片化和个性化需求的增长使得用户在海量的美食信息中寻找到适合自己的内容变得困难。因此，开发一个基于Java的美食信息推荐系统，能够根据用户的个人喜好和饮食习惯，智能推荐个性化的菜谱和饮食资讯，对于提升用户体验和满足用户需求具有重要意义。该系统的设计和实现还将涉及到用户界面(UI)的友好性、系统的可扩展性、数据的安全性和隐私保护等方面，这些都是当前互联网应用开发中的关键问题。通过本课题的研究，不仅可以推动美食信息推荐技术的创新，还可以为相关领域的研究和实践提供参考，具有较高的学术价值和实际应用价值。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。
