运行环境

Java≥8、MySQL≥5.7

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb+mysql的SpringBoot简单博客管理系统(java+springboot+html+maven+mysql)

项目介绍

本项目为前后台管理系统，包括博主与游客两种角色；博主角色包含以下功能：博主登录,发博客,博主可以删除博客等功能。游客角色包含以下功能：首页,查看博客,添加评论,搜索-标签筛选等功能。

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。 2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA; 3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可 4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；

5.数据库：MySql 5.7版本；

技术栈

后端：SpringBoot
前端：HTML+CSS+JavaScript+jsp

使用说明

使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件； 2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行； 3. 将项目中application.yml配置文件中的数据库配置改为自己的配置; 4. 运行项目，输入localhost:8080/ 登录
