目录一、项目简介二、环境介绍三、系统展示四、核心代码展示五、项目总结

一、项目简介

本项目使用springboot+mybatis+前端vue,使用前后端分离架构实现的个人博客系统,共7个模块,首页,写博客,博客详情页,评论管理,文章分类,标签管理和文章归档。该项目没有后端管理功能,比较适合用于大作业!

二、环境介绍

语言环境:java:  jdk1.8

数据库:mysql: mysql5.7/redis

应用服务器:Tomcat:  tomcat8.5.31

开发工具:IDEA或eclipse

项目管理工具: maven

三、系统展示

首页

文章分类

标签

登录

发布文章

四、核心代码展示
