基于javaweb+springboot的新闻发布管理系统

基于javaweb+springboot的新闻发布管理系统(java+Springboot+ssm+mysql+maven)

一、项目简述
功能： 区分为管理员用户和普通用户，管理员用户能删除评论， 调整新闻显示/隐藏，修改新闻，删除普通用户，普通用户能 登陆浏览，新用户可以注册基本功能实现了新闻增加，新 闻删除，新闻修改，新闻搜索其他功能：用户评论，管理 员删除差评，新闻分类，前台分类显示新闻，用户注册， 登录，个人信息修改等等功能。

二、项目运行
环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)

项目技术： JSP + SpringBoot + Servlert + htm l+ css + JavaScript + ECharts+ JQuery + Maven 等等

适用

课程设计，大作业，毕业设计，项目练习，学习演示等
