Thymeleaf的基本用法整理

10th of August 2017 Java Java 2624

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

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
    <head>
        <title>Thymeleaf tutorial: exercise 2</title>
        <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
        <meta charset="utf-8" />
    </head>
    <body>
        <h1>Thymeleaf tutorial - Answer for exercise 1: bean values</h1>
        <h2>Product information</h2>
        <dl>
            <dt>Product name</dt>
            <dd th:text="${product.description}">Red Chair</dd>
            <dt>Product price</dt>
            <dd th:text="${product.price}">350</dd>
            <dt>Product available from</dt>
            <dd th:text="${product.availableFrom}">2014-12-01</dd>
        </dl>
    </body>
</html>


2.简单数据转换(数字,日期)

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
    <head>
        <title>Thymeleaf tutorial: exercise 2</title>
        <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
        <meta charset="utf-8" />
    </head>
    <body>
        <h1>Thymeleaf tutorial - Answer for exercise 2: bean values</h1>
        <h2>Product information</h2>
        <dl>
            <dt>Product name</dt>
            <dd th:text="${product.description}">red Chair</dd>
            <dt>Product price</dt>
            <dd th:text="${#numbers.formatDecimal(product.price, 1, 2)}">180</dd>
            <dt>Product available from</dt>
            <dd th:text="${#dates.format(product.availableFrom, 'yyyy-MM-dd')}">2014-12-01</dd>
        </dl>
    </body>
</html>


3.字符串拼接

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
    <head>
        <title>Thymeleaf tutorial: exercise 3</title>
        <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
        <meta charset="utf-8" />
    </head>
    <body>
        <h1>Thymeleaf tutorial - Answer for exercise 3: string concatenation</h1>
        <h2>Product information</h2>
        <dl>
            <dt>Product price</dt>
            <dd th:text="${'$'+product.price}">235</dd>
        </dl>
    </body>
</html>


4.国际化


点击该连接查看:thymeleaf获取配置properties中的数据与thymeleaf国际化


5.转义和非转义文本

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
    <head>
        <title>Thymeleaf tutorial: exercise 5</title>
        <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" />
        <meta charset="utf-8" />
    </head>
    <body>
        <h1>Thymeleaf tutorial - Solution for exercise 5: escaped and unescaped text</h1>
        <div th:text="${html}">
            Some escaped text
        </div>
        <div th:utext="${html}">
            Some unescaped text
        </div>
    </body>
</html>

上述两个div分别生成的html代码为

<div>This is an &lt;em&gt;HTML&lt;/em&gt; text. &lt;b&gt;Enjoy yourself!&lt;/b&gt;</div>
<div>This is an <em>HTML</em> text. <b>Enjoy yourself!</b></div>


6.迭代
