1、簡單表示式
變量表達式 ${... ...}
<input type="text" name="userName" value="James Carrot" th:value 上述程式碼為引用user物件的name屬性值
選擇/星號表示式*{*** ***}
<div th:object="${session.user}"> <p 文字國際化表示式 #{... ...}
<p th:utext="#{home.welcome}">Welcome to our grocery store!</p>
resource_en_US.properties：home.welcome=Welcome to here！resource_zh_CN.properties：home.welcome=歡迎您的到來！
URL表示式 @{... ...}
<a href="details.html" th:href="@{/order/details(orderId=${o.id})}">view</a>當URL為後臺傳出的引數時，程式碼如下：
<img src="../../static/assets/images/qr-code.jpg" th:src="@{${path}}" alt="二維碼" />2、常用的th標籤
簡單資料轉換（數字，日期）
<dt>價格</dt> <dd th:text="${#numbers.formatDecimal(product.price, 1, 2)}">180</dd> <dt>進貨日期</dt> <dd th:text="${#dates.format(product.availableFrom, 'yyyy-MM-dd')}">2014-12-01</dd>字串拼接
<dd th:text="${'$'+product.price}">235</dd>轉義和非轉義文字
當後臺傳出的資料為"This is an <em>HTML</em> text. <b>Enjoy yourself!</b>"時，若頁面程式碼如下則出現兩種不同的結果
<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>表單中
<form th:action="@{/bb}" th:object="${user}" method="post" th:method="post"> <input type="text" th:field="*{name}"/> <input type="text" th:field="*{msg}"/> <input type="submit"/></form>顯示頁面的資料迭代
//用 th:remove 移除除了第一個外的靜態資料，用第一個tr標籤進行迴圈迭代顯示 <tbody th:remove="all-but-first"> //將後臺傳出的 productList 的集合進行迭代，用product引數接收，通過product訪問屬性值 <tr th:each="product:${productList}"> //用count進行統計，有順序的顯示 <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>$200</td> <td>15-Jul-2013</td> </tr> </tbody>條件判斷
<span th:if="${product.price lt 100}" class="offer">Special offer!</span>
<!-- 當gender存在時，選擇對應的選項；若gender不存在或為null時，取得customer物件的name--><td th:switch="${customer.gender?.name()}"> <img th:case="'MALE'" src="../../../images/male.png" th:src="@{/images/male.png}" alt="Male" /> <!-- Use "/images/male.png" image --> <img th:case="'FEMALE'" src="../../../images/female.png" th:src="@{/images/female.png}" alt="Female" /> <!-- Use "/images/female.png" image --> <span th:case="*">Unknown</span></td><!-- 增加class="enhanced"當balance大雨10000 --><td th:class="${customer.balance gt 10000} ? 'enhanced'" th:text="${customer.balance}">350</td>根據後臺資料選中select的選項
因為gender是定義的num（列舉）型別，所以要用toString方法。用th:switch指定傳出的變數，用th:case對變數的值進行匹配。!"請選擇"放在第一項會出現永遠選擇的是這個選項。或者用th:if
<div class='form-group col-lg-4'> <select class='form-control' name="skill[4].proficiency"> <option >掌握程度</option> <option th:if="${skill.level eq '一般'}" th:selected="selected">一般</option> <option th:if="${skill.level eq '熟練'}" th:selected="selected">熟練</option> <option th:if="${skill.level eq '精通'}" th:selected="selected">精通</option> </select></div>spring表示式語言
