SpringBoot前后端分离项目实战

# 项目实战-前后端分离博客系统 ## 1.课程介绍 * 纯后端讲解 * 完整的前台后台代码编写 * 主流技术栈（SpringBoot,MybatisPlus,SpringSecurity,EasyExcel,Swagger2,Redis,Echarts,Vue,ElementUI....） * 完善细致的需求分析 * 由易到难循序渐进 ## 2.创建工程 ​ 我们有前台和后台两套系统。两套系统的前端工程都已经提供好了。所以我们只需要写两套系统的后端。 ​ 但是大家思考下，实际上两套后端系统的很多内容是可能重复的。这里如果我们只是单纯的创建两个后端工程。那么就会有大量的重复代码，并且需要修改的时候也需要修改两次。这就是代码复用性不高。 ​ 所以我们需要创建多模块项目，两套系统可能都会用到的代码可以写到一个公共模块中，让前台系统和后台系统分别取依赖公共模块。 ① 创建父模块 ~~~~xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"
