Thymeleaf是个XML/XHTML/HTML5模板引擎，可以用于Web与非Web应用。
Thymeleaf的主要目标在于提供一种可被浏览器正确显示的、格式良好的模板创建方式，因此也可以用作静态建模。你可以使用它创建经过验证的XML与HTML模板。相对于编写逻辑或代码，开发者只需将标签属性添加到模板中即可。接下来，这些标签属性就会在DOM（文档对象模型）上执行预先制定好的逻辑。Thymeleaf的可扩展性也非常棒。你可以使用它定义自己的模板属性集合，这样就可以计算自定义表达式并使用自定义逻辑。这意味着Thymeleaf还可以作为模板引擎框架。
Thymeleaf的模板还可以用作工作原型，Thymeleaf会在运行期替换掉静态值。例如下面的html文件，当作为静态文件时，product name显示为Red Chair，当运行在容器中并提供product这个对象时，product name的值会自动替换为product.description对应的值。
1.bean值替换
1 <!DOCTYPE html>
2 <html xmlns:th="http://www.thymeleaf.org">
3 <head>
4 <title>Thymeleaf tutorial: exercise 2</title>
5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
6 <meta charset="utf-8" />

8 <body>
9 <h1>Thymeleaf tutorial - Answer for exercise 1: bean values</h1>
10 <h2>Product information</h2>
11 <dl>
12 <dt>Product name</dt>
13 <dd th:text="${product.description}">Red Chair</dd>
14
15 <dt>Product price</dt>
16 <dd th:text="${product.price}">350</dd>
17
18 <dt>Product available from</dt>
19 <dd th:text="${product.availableFrom}">2014-12-01</dd>
20 </dl>
21 </body>
22 </html>
2.简单数据转换（数字，日期）
1 <!DOCTYPE html>
2 <html xmlns:th="http://www.thymeleaf.org">
3 <head>
4 <title>Thymeleaf tutorial: exercise 2</title>
5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
6 <meta charset="utf-8" />
7 </head>
8 <body>
9 <h1>Thymeleaf tutorial - Answer for exercise 2: bean values</h1>
10 <h2>Product information</h2>
11 <dl>
12 <dt>Product name</dt>
13 <dd th:text="${product.description}">red Chair</dd>
14
15 <dt>Product price</dt>
16 <dd th:text="${#numbers.formatDecimal(product.price, 1, 2)}">180</dd>
17
18 <dt>Product available from</dt>
19 <dd th:text="${#dates.format(product.availableFrom, 'yyyy-MM-dd')}">2014-12-01</dd>
20 </dl>
21 </body>
22 </html>
3.字符串拼接
1 <!DOCTYPE html>
2 <html xmlns:th="http://www.thymeleaf.org">
3 <head>
4 <title>Thymeleaf tutorial: exercise 3</title>
5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
6 <meta charset="utf-8" />
7 </head>
8 <body>
9 <h1>Thymeleaf tutorial - Answer for exercise 3: string concatenation</h1>
10 <h2>Product information</h2>
11 <dl>
12 <dt>Product price</dt>
13 <dd th:text="${'$'+product.price}">235</dd>
14 </dl>
15 </body>
16 </html>
4.国际化
1 <!DOCTYPE html>
2 <html xmlns:th="http://www.thymeleaf.org">
3 <head>
4 <title th:text="#{tutorial.exercise4}">Thymeleaf tutorial: exercise 4</title>
5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
6 <meta charset="utf-8" />
7 </head>
8 <body>
9 <h1 th:text="#{tutorial.exercise4}">Thymeleaf tutorial - Solution for exercise 4: internationalization</h1>
10 <h2 th:text="#{product.info}">Product information</h2>
11 <dl>
12 <dt th:text="#{product.name}">Product name</dt>
13 <dd th:text="${product.description}">Red chair</dd>
14
15 <dt th:text="#{product.price}">Product price</dt>
16 <dd th:text="${#numbers.formatDecimal(product.price, 1, 2)}">350</dd>
17
18 <dt th:text="#{product.available}">Product available from</dt>
19 <dd th:text="${#dates.format(product.availableFrom, 'dd-MMM-yyyy')}">28-Jun-2013</dd>
20 </dl>
21 </body>
22 </html>
此时html需要相应的配置文件。例如如下配置文件：
en：
tutorial.exercise4=Thymeleaf tutorial - exercise 4: internationalization product.info=Product information product.name=Product name product.price=Product price product.available=Product available from back=Back
fr
tutorial.exercise4=Tutorial De Thymeleaf - exercice 4: l'internationalisation product.info=Information du produit product.name=Nom du produit product.price=Prix du produit product.available=Produit disponible depuis back=Revenir
5.转义和非转义文本

4 <title>Thymeleaf tutorial: exercise 5</title>
5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
6 <meta charset="utf-8" />
7 </head>
8 <body>
9 <h1>Thymeleaf tutorial - Solution for exercise 5: escaped and unescaped text</h1>
10 <div th:text="${html}">
11 Some escaped text
12 </div>
13 <div th:utext="${html}">
14 Some unescaped text
15 </div>
16 </body>
17 </html>
上述两个div分别生成的html代码为
<div>This is an <em>HTML</em> text. <b>Enjoy yourself!</b></div> <div>This is an <em>HTML</em> text. <b>Enjoy yourself!</b></div>
6.迭代
