Thymeleaf標籤整理

1、簡單表示式
變量表達式 ${... ...}
<input type="text" name="userName" value="James Carrot" th:value="${user.name}" />
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="${session.user}"> <p>Nationality: <span th:text="*{nationality}">Saturn</span>.</p> </div>
選擇表示式一般跟在th:object後，直接取object中的屬性
文字國際化表示式 #{... ...}
<p th:utext="#{home.welcome}">Welcome to our grocery store!</p>呼叫國際化的welcome語句，國際化資原始檔如下
resource_en_US.properties：home.welcome=Welcome to here！resource_zh_CN.properties：home.welcome=歡迎您的到來！URL表示式 @{... ...}
<a href="details.html" th:href="@{/order/details(orderId=${o.id})}">view</a>
@{... ...}支援決定路徑和相對路徑。其中相對路徑又支援跨上下文呼叫url和協議的引用 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>不能用"<"，">"等符號，要用"lt"等替代
<!-- 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="${customer.gender?.name()}">
<img th:case="'MALE'" src="../../../images/male.png" th:src="@{/images/male.png}" alt="Male" /> <!-- Use "/images/male.png" image -->
<img th:case="'FEMALE'" src="../../../images/female.png" th:src="@{/images/female.png}" alt="Female" /> <!-- Use "/images/female.png" image -->
<span th:case="*">Unknown</span>
</td>根據後臺資料選中select的選項
因為gender是定義的num（列舉）型別，所以要用toString方法。用th:switch指定傳出的變數，用th:case對變數的值進行匹配。!"請選擇"放在第一項會出現永遠選擇的是這個選項。或者用th:if
<div class='form-group col-lg-4'>
<select class='form-control' name="skill[4].proficiency">
<option >掌握程度</option>
<option th:if="${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>
