大家好，我是java1234_小锋老师，看到一个不错的SpringBoot+Vue图书(图书借阅)管理系统，分享下哈。

【免费】SpringBoot+Vue新闻发布推荐系统 Java毕业设计_哔哩哔哩_bilibili
项目介绍
随着信息互联网购物的飞速发展，国内放开了自媒体的政策，一般企业都开始开发属于自己内容分发平台的网站。本文介绍了新闻推荐系统的开发全过程。通过分析企业对于新闻推荐系统的需求，创建了一个计算机管理新闻推荐系统的方案。文章介绍了新闻推荐系统的系统分析部分，包括可行性分析等，系统设计部分主要介绍了系统功能设计和数据库设计。
本新闻推荐系统有管理员和用户两个角色。管理员功能有个人中心，用户管理，排行榜管理，新闻管理，我的收藏管理，系统管理等。用户功能可以在首页查看新闻排行榜，新闻信息，并可以注册登录，收藏新闻，对新闻评论。用户注册登录，评论新闻，收藏新闻，查看新闻，搜索新闻。因而具有一定的实用性。
本站是一个B/S模式系统，采用Spring Boot框架作为开发技术，MYSQL数据库设计开发，充分保证系统的稳定性。系统具有界面清晰、操作简单，功能齐全的特点，使得新闻推荐系统管理工作系统化、规范化。
