1、简单表达式

变量表达式 ${... ...}

<input type="text" name="userName" value="James Carrot" th:value="${user.name}" />

上述代码为引用user对象的name属性值


选择/星号表达式*{*** ***}

<div th:object="${session.user}">                                                                            <p>Nationality: <span th:text="*{nationality}">Saturn</span>.</p>    </div>
选择表达式一般跟在th:object后,直接取object中的属性


文字国际化表达式 #{... ...}

<p th:utext="#{home.welcome}">Welcome to our grocery store!</p>
调用国际化的welcome语句,国际化资源文件如下

resource_en_US.properties:home.welcome=Welcome to here!resource_zh_CN.properties:home.welcome=欢迎您的到来!

URL表达式 @{... ...}

<a href="details.html" th:href="@{/order/details(orderId=${o.id})}">view</a>
@{... ...}支持决定路径和相对路径。其中相对路径又支持跨上下文调用url和协议的引用
当URL为后台传出的参数时,代码如下:

<img src="../../static/assets/images/qr-code.jpg" th:src="@{${path}}" alt="二维码" />

2、常用的th标签

简单数据转换(数字,日期)

<dt>价格</dt>    <dd th:text="${#numbers.formatDecimal(product.price, 1, 2)}">180</dd>   <dt>进货日期</dt>   <dd th:text="${#dates.format(product.availableFrom, 'yyyy-MM-dd')}">2014-12-01</dd>


字符串拼接

<dd th:text="${'$'+product.price}">235</dd>

转义和非转义文本

当后台传出的数据为"This is an &lt;em&gt;HTML&lt;/em&gt; text. &lt;b&gt;Enjoy yourself!&lt;/b&gt;"时,若页面代码如下则出现两种不同的结果

<div th:text="${html}">  This is an <em>HTML</em> text. <b>Enjoy yourself!</b></div> <div th:utext="${html}">  This is an <em>HTML</em> text. <b>Enjoy yourself!</b></div>

表单中

<form th:action="@{/bb}" th:object="${user}" method="post" th:method="post">    <input type="text" th:field="*{name}"/>    <input type="text" th:field="*{msg}"/>    <input type="submit"/></form>

显示页面的数据迭代

           //用 th:remove 移除除了第一个外的静态数据,用第一个tr标签进行循环迭代显示               <tbody th:remove="all-but-first">          //将后台传出的 productList 的集合进行迭代,用product参数接收,通过product访问属性值                <tr th:each="product:${productList}">            //用count进行统计,有顺序的显示            <td th:text="${productStat.count}">1</td>                    <td th:text="${product.description}">Red Chair</td>                    <td th:text="${'$' + #numbers.formatDecimal(product.price, 1, 2)}">$123</td>                    <td th:text="${#dates.format(product.availableFrom, 'yyyy-MM-dd')}">2014-12-01</td>                </tr>                <tr>                    <td>White table</td>                    <td>$200</td>                    <td>15-Jul-2013</td>                </tr>                <tr>                    <td>Reb table</td>                    <td>$200</td>                    <td>15-Jul-2013</td>                </tr>                <tr>                    <td>Blue table</td>                    <td>$200</td>                    <td>15-Jul-2013</td>                </tr>      </tbody>

条件判断

<span th:if="${product.price lt 100}" class="offer">Special offer!</span>
不能用"<",">"等符号,要用"lt"等替代

<!-- 当gender存在时,选择对应的选项;若gender不存在或为null时,取得customer对象的name--><td th:switch="${customer.gender?.name()}">    <img th:case="'MALE'" src="../../../images/male.png" th:src="@{/images/male.png}" alt="Male" /> <!-- Use "/images/male.png" image -->    <img th:case="'FEMALE'" src="../../../images/female.png" th:src="@{/images/female.png}" alt="Female" /> <!-- Use "/images/female.png" image -->    <span th:case="*">Unknown</span></td>
<!-- 增加class="enhanced"当balance大雨10000 --><td th:class="${customer.balance gt 10000} ? 'enhanced'" th:text="${customer.balance}">350</td>

根据后台数据选中select的选项

因为gender是定义的num(枚举)类型,所以要用toString方法。用th:switch指定传出的变量,用th:case对变量的值进行匹配。!"请选择"放在第一项会出现永远选择的是这个选项。或者用th:if

<div class='form-group col-lg-4'>          <select class='form-control' name="skill[4].proficiency">                <option >掌握程度</option>                <option th:if="${skill.level eq '一般'}" th:selected="selected">一般</option>                 <option th:if="${skill.level eq '熟练'}" th:selected="selected">熟练</option>                 <option th:if="${skill.level eq '精通'}" th:selected="selected">精通</option>           </select></div>

spring表达式语言

<!DOCTYPE html><html xmlns:th="http://www.thymeleaf.org">    <head>        <title>Thymeleaf tutorial: exercise 10</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 10: Spring Expression language</h1>          <h2>Arithmetic expressions</h2>        <p class="label">Four multiplied by minus six multiplied by minus two module seven:</p>        <p class="answer" th:text="${4 * -6 * -2 % 7}">123</p>         <h2>Object navigation</h2>        <p class="label">Description field of paymentMethod field of the third element of customerList bean:</p>        <p class="answer" th:text="${customerList[2].paymentMethod.description}">Credit card</p>         <h2>Object instantiation</h2>        <p class="label">Current time milliseconds:</p>        <p class="answer" th:text="${new java.util.Date().getTime()}">22-Jun-2013</p>                <h2>T operator</h2>        <p class="label">Random number:</p>        <p class="answer" th:text="${T(java.lang.Math).random()}">123456</p>    </body></html>

内联

<label for="body">Message body:</label><textarea id="body" name="body" th:inline="text">Dear [[${customerName}]],it is our sincere pleasure to congratulate your in your birthday:    Happy birthday [[${customerName}]]!!!See you soon, [[${customerName}]].Regards,    The Thymeleaf team</textarea>

内联JS<js起止加入如下代码,否则引号嵌套或者"<"">"等不能用>

/*<![CDATA[*/……/*]]>*/


js附加代码:

/*[+var msg = 'This is a working application';+]*/


js移除代码

/*[- */var msg = 'This is a non-working template';/* -]*/
