简单的后台管理系统demo（基于Spring Boot）

#工程实践#Spring Boot#Java

前言

工程实践2和期末考试终于结束了，有空来写一下快速打通前后端的一个demo。其实是基于工程实践2项目的基础上进行优化和阉割的，因为原项目相较于即将写的这个demo大不少了。
本文会将一些主要文件展示出来，不会展示完所有文件。
因为项目中用到的文件相对来说比较多，全部在本文中写出来会导致篇幅会十分巨大，所以推荐先去下载项目源代码，然后配合本文食用。

实现的功能

实现登录功能、页面自动显示查询到的信息、运营账号的增删查改，多条件查询（mybatis动态查询）

正文

系统架构草图

项目结构

 
红框中的文件大家如果能大概搞明白，本文的目的就达到了。

IDEA新建项目

这里没演示maven的设置，不知道怎么设置的去查一下
