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" />

Thymeleaf简单例子

遍历后台数据

<!--最新上架--> 
        <div class="first-pannel clearfix"> 
            <div class="index-f clearfix"> 
                <h3 class="index-f-head"> 最新上架 <span>每天都有上新,每天都有惊喜</span> </h3> 
                <div class="index-f-body"> 
                    <div class="top-sales newProduct"> 
                        <ul class="top-sales-list clearfix"> 
                            <li class="top-sales-item newProduct" th:each="item : ${items}"> 
                                <p class="item-img"> <a th:href="@{'/portal/item/toDetail/'+${item.spuId}+'/'+${item.skuId}}"><img th:src="@{${item.imgPath}}" /></a> </p> 
                                <p class="item-buss"><a th:href="@{'/portal/item/toDetail/'+${item.spuId}+'/'+${item.skuId}}"></a></p> 
                                <p class="item-name spec"><a th:href="@{'/portal/item/toDetail/'+${item.spuId}+'/'+${item.skuId}}" th:text="${item.itemName}"></a></p> 
                                <p class="item-price spec"><em th:text="${item.mPrice}"></em>元</p> 
                            </li> 
                        </ul>

                </div> 
            </div> 
        </div> 
        <!--最新上架//-->

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 

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> 
    <script type="text/javascript" th:src="@{/static/js/html5.js}"></script> 
    <script type="text/javascript" th:src="@{/static/js/popbox.js}"></script>

给出一个html页面例子:

<!DOCTYPE HTML> 
<html xmlns="http://www.w3.org/1999/xhtml" 
      xmlns:th="http://www.thymeleaf.org">
