标签（空格分隔）： sringboot adminlte thymeleaf
spring boot 和 adminlte没有紧密的联系，只是最近在做的一个东西用spring boot做后端用adminlte做前端，所以就放到spring boot系列里面讲。
架构原理
adminlte只是一个库，说不上什么框架，所以不好说架构原理，他是基于bootstrap做的一个东西
adminlte的layout
暂时基本上只用了adminlte的layout，所以介绍一下adminlte的layout
安装
到 https://github.com/almasaeed2010/AdminLTE 下载，然后解压到spring boot项目的 src\main\resources\static 下面就可以了
最简单的例子
layout.html

把 starter.html 的一些不是必须的东西去掉就变成上面这样了，进一步的 Logo和Content Header (Page header) 部分也可以不要的，但是页面看上去会很难看。
上面的代码中关键的部分是<div class="wrapper">，<header class="main-header">，<aside class="main-sidebar">，还有<div class="content-wrapper">，这些就是adminlte layout的主要组成部分。
关键的问题
用adminlte做东西肯定要实现点击sidebar中的菜单切换content-wrapper中的内容的功能。
问题是sidebar每一条菜单都对应一个html，每个html都包含相同的内容（main-header，main-sidebar部分的内容），所以这可以抽象成模板的问题，而thymeleaf正好是一个模板解决方案。换句话说，就是让adminlte的layout作为thymeleaf的一个layout来解决这个问题，这个问题在介绍thymeleaf的时候再讲
