简单介绍
目前在JavaEE领域有几中比较常用的模板引擎，分别是Jsp、Velocity、Freemarker、Thymeleaf，对Freemark语法不是特别熟悉，不过对于前端页面渲染效率来说，jsp其实还是最快的，Velocity次之。Thymeleaf虽然渲染效率不是很快，但是语法方面是比较轻巧的，Thymeleaf语法比Velocity轻巧，但是渲染效率不如Velocity
maven配置
因为引入了SpringBoot的parent工程，所以不需要写版本号

添加html文件
在resources资源文件夹下面新建一个templates文件夹，所有的html文件都丢在这里，静态资源文件也丢在resources资源文件夹下面
新建一个html文件，然后注意加上<html xmlns:th="http://www.thymeleaf.org">
注意Thymeleaf语法要求比较严格 <meta charset="utf-8" >，不如这样写是不可以的，必须加上斜杠的，<meta charset="utf-8" />

引入文件
Thymeleaf引入另外一个html文件可以使用th:replace或者th:include，
<!--topBar-->
<div class="topBar" th:replace="/top_bar :: .topBar"></div>
<!--//topBar-->
<!--headerMain-->
<div class="headerMain layout clearfix" th:replace="/header_main :: .headerMain"></div>
<!--//headerMain-->
<!--headerNav-->
<div class="headerNav" th:replace="/index_header_nav :: .headerNav"></div>
<!--//headerNav-->
Img便签src
<img th:src="@{/static/images/rachange_ad.jpg}" />
链接<a>便签
<a th:href="@{'/portal/item/toDetail/'+{item.skuId}}"><img th:src="@{${item.imgPath}}" /></a>
静态资源使用
<link th:href="@{/static/css/public.css}" rel="stylesheet" type="text/css" />
<link th:href="@{/static/css/index.css}" rel="stylesheet" type="text/css" />
<script type="text/javascript" th:src="@{/static/js/jquery-1.3.2.min.js}"></script>
