thymeleaf參考手冊

1、創建html

    <!DOCTYPE html><html xmlns:th="http://www.thymeleaf.org"></html>
另外：xmlns:layout="http://www.ultraq.net.nz/web/thymeleaf/layout".

th:* attributes ： 

layout:* attributes</code><ul class="pre-numbering" style=""><li style="color: rgb(153, 153, 153);">1</li><li style="color: rgb(153, 153, 153);">2</li><li style="color: rgb(153, 153, 153);">3</li><li style="color: rgb(153, 153, 153);">4</li><li style="color: rgb(153, 153, 153);">5</li><li style="color: rgb(153, 153, 153);">6</li><li style="color: rgb(153, 153, 153);">7</li></ul></pre>

注意：html 中的標籤必須嚴格規範，標籤必須閉合，即<div />技術或者</div>類似結束

2、使用文本

語法	說明
{home.welcome}	使用國際化文本,國際化傳參直接追加(value…)
${user.name}	使用會話屬性
@{}	`<link rel="stylesheet" type="text/css" media="all"href="../../css/gtvg.css" th:href="@{/css/gtvg.css}" />`
–	–
${} 中預存對象（表達式中基本對象）
param	獲取請求參數，比如${param.name},http://localhost:8080?name=jeff
session	獲取 session 的屬性
application	獲取 application 的屬性
execInfo	有兩個屬性 templateName和 now(是 java 的 Calendar 對象)
ctx
vars
locale
httpServletRequest
httpSession
–	–
th擴展標籤
th:text	普通字符串
th:utext	轉義文本
th:href
th:attr	`<img src="../../images/gtvglogo.png" th:attr="src=@{/images/gtvglogo.png},title=#{logo},alt=#{logo}" />`
th:with	定義常量
th:attrappend
th:classappend
th:styleappend

其他th標籤

th:abbr	th:accept	th:accept-charset
th:accesskey	th:action	th:align
th:alt	th:archive	th:audio

th:value	th:valuetype	th:vspace
th:width	th:wrap	th:xmlbase
th:xmllang	th:xmlspace	th:alt-title 或th:lang-xmllang（如果其中兩個屬性值相同）

對於 html5 元素名稱的另一種友好寫法

<table>
    <tr data-th-each="user : ${users}">
    <td data-th-text="${user.login}">...</td>
    <td data-th-text="${user.name}">...</td> </tr>
</table>

3、表達式語法

1、簡單表達式語法

#{...} : Message 表達式

<p th:utext="#{home.welcome(${session.user.name})}"> Welcome to our grocery store, Sebastian Pepper!</p>
<p th:utext="#{${welcomeMsgKey}(${session.user.name})}"> Welcome to our grocery store, Sebastian Pepper!</p>

${}:變量表達式

ongl標準語法，方法也可以被調用

*{} ：選擇變量表達式

<div th:object="${session.user}">
    <p>Name: <span th:text="*{firstName}">Sebastian</span>.</p>
    <p>Surname: <span th:text="*{lastName}">Pepper</span>.</p> 
    <p>Nationality: <span th:text={nationality}">Saturn</span>.</p>
</div> 
等價於
<div>
    <p>Name: <span th:text="${session.user.firstName}">Sebastian</span>.</p> 
    <p>Surname: <span th:text="${session.user.lastName}">Pepper</span>.</p> 
    <p>Nationality: <span th:text="${session.user.nationality}">Saturn</span>.</p>
</div>
當然了，這兩者可以混合使用
還有一種方式
<div>
    <p>Name: <span th:text="*{session.user.name}">Sebastian</span>.</p> 
    <p>Surname: <span th:text="*{session.user.surname}">Pepper</span>.</p> 
    <p>Nationality: <span th:text="*{session.user.nationality}">Saturn</span>.</p>
</div>

@{}: 鏈接 URL 表達式

<!-- Will produce 'http://localhost:8080/gtvg/order/details?orderId=3' (plus rewriting) --> <a href="details.html"

th:href="@{http://localhost:8080/gtvg/order/details(orderId=${o.id})}">view</a> <!-- Will produce '/gtvg/order/details?orderId=3' (plus rewriting) -->

<a href="details.html" th:href="@{/order/details(orderId=${o.id})}">view</a>

<!-- Will produce '/gtvg/order/3/details' (plus rewriting) -->

<a href="details.html" th:href="@{/order/{orderId}/details(orderId=${o.id})}">view</a>

2、變量

分類	示例
文本	‘one text’ , ‘Another one!’ ,…
數字	0 , 34 , 3.0 , 12.3 ,…
真假	true , false
文字符號	one , sometext , main ,…

3、字符連接

分類	示例
+	‘The name is ‘+${name}
\|…\|	\|The name is ${name}\|

4、算數運算

語法	示例
+, -, *, /, %	二元運算符
-	減號（一元運算符）

5、真假運算

分類	示例
and , or	二元運算符
! , not	否定（一元運算符）

6、比較運算

分類	示例
>, <, >=, <= (gt, lt, ge, le)	比較
== , != ( eq , ne )	平等

7、條件運算

分類	示例
if-then	(if) ? (then)
if-then-else	(if) ? (then) : (else)
Default	(value) ?: (defaultvalue)

綜合示例：

'User is of type ' + (${user.isAdmin()} ? 'Administrator' : (${user.type} ?: 'Unknown'))

4、表達式中使用內置對象

#dates :

utility methods for java.util.Date objects: formatting, component extraction, etc. #calendars : analogous to #dates , but for java.util.Calendar objects.

#numbers :
utility methods for formatting numeric objects.

#strings : 
utility methods for String objects: contains, startsWith, prepending/appending, etc. #objects : utility methods for objects in general.

#bools : 
utility methods for boolean evaluation. #arrays : utility methods for arrays.

#lists :
utility methods for lists.

#sets : 
utility methods for sets.

#maps : 
utility methods for maps.

#aggregates : 
utility methods for creating aggregates on arrays or collections.

#messages : 
utility methods for obtaining externalized messages inside variables expressions, in the same way as they would be obtained using #{...} syntax.

#ids : 
utility methods for dealing with id attributes that might be repeated (for example, as a result of an iteration).

5、預處理

__${expression}__

6、循環

<tr th:each="prod : ${prods}">
    <td th:text="${prod.name}">Onions</td>
    <td th:text="${prod.price}">2.41</td>
    <td th:text="${prod.inStock}? #{true} : #{false}">yes</td>
</tr>

迭代器的狀態
index: 當前的索引，從0開始
count: 當前的索引，從1開始
size：總數
current:
even/odd:
first
last
<table> 
    <tr>
        <th>NAME</th>
        <th>PRICE</th>
        <th>IN STOCK</th>
    </tr>
    <tr th:each="prod,iterStat : ${prods}" th:class="${iterStat.odd}? 'odd'">
    <td th:text="${prod.name}">Onions</td>
    <td th:text="${prod.price}">2.41</td>
    <td th:text="${prod.inStock}? #{true} : #{false}">yes</td>
  </tr>
</table>

7、判斷


if

<a href="comments.html" th:href="@{/product/comments(prodId=${prod.id})}" th:if="${not #lists.isEmpty(prod.comments)}">view</a>

unless

<a href="comments.html" th:href="@{/comments(prodId=${prod.id})}" th:unless="${#lists.isEmpty(prod.comments)}">view</a>

switch

<div th:switch="${user.role}">
    <p th:case="'admin'">User is an administrator</p> <p th:case="#{roles.manager}">User is a manager</p>
</div>

<div th:switch="${user.role}">
    <p th:case="'admin'">User is an administrator</p> <p th:case="#{roles.manager}">User is a manager</p> <p th:case="*">User is some other thing</p>
</div>

8、模板佈局

th:fragment

示例

templates/footer.html

<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-4.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"
    <body>
         <div th:fragment="copy">
            © 2011 The Good Thymes Virtual Grocery
         </div>
    </body>
</html>

templates/index.html中使用

    <body> ...
        <div th:include="footer :: copy"></div> 
    </body>

或者
    ...
    <div id="copy-section">
        © 2011 The Good Thymes Virtual Grocery 
    </div>
    ...

使用

    <body> ...
        <div th:include="footer :: #copy-section"></div>
    </body>


th:include 和 th:replace 區別

th:include 加入代碼

th:replace 替換代碼

模板傳參：參數傳遞順序不強制

    定義

<div th:fragment="frag (onevar,twovar)">
    <p th:text="${onevar} + ' - ' + ${twovar}">...</p>
</div>

    使用

<div th:include="::frag (${value1},${value2})">...</div>

<div th:include="::frag (onevar=${value1},twovar=${value2})">...</div> 
等價於 <div th:include="::frag" th:with="onevar=${value1},twovar=${value2}">）

9、移除標籤 th:remove

取值範圍

all：移除所有
body：不移除自己，但移除他的子標籤
tag: 只移除自己，不移除他的子標籤
all-but-first：移除所有內容除第一個外
none：啥都不做

10、執行順序

11、thymeleaf註釋語法

html 看不到，並且 thymeleaf 不會執行

<!--/* This code will be removed at thymeleaf parsing time! */-->

and 未運行可以在 html 中看到，運行後就消失

<!--/*-->
   <div>you can see me only before thymeleaf processes me! </div>
<!--*/-->

運行後纔會看到

<span>hello!</span>
<!--/*/
<div th:text="${true}">...</div>
/*/-->
<span>goodbye!</span>

12、th:block 的使用

<table>
    <th:block th:each="user : ${users}">
    <tr>
        <td th:text="${user.login}">...</td> <td th:text="${user.name}">...</td>
    </tr>
    <tr>
        <td colspan="2" th:text="${user.address}">...</td> 
    </tr>
    </th:block>
</table>

推薦下面寫法（編譯前看不見）

<table>
    <tr>
        <td th:text="${user.login}">...</td>
        <td th:text="${user.name}">...</td> </tr>
        <tr>
        <td colspan="2" th:text="${user.address}">...</td>
    </tr>
    <!--/*/ </th:block> /*/--> 
</table>

13、文本內聯th:inline

th:inline 可以等於 text , javascript(dart) , none

text: [[…]]

<p th:inline="text">Hello, [[#{test}]]</p>

javascript: /[[…]]/

<script th:inline="javascript">
    var username = /*[[
        #{test}
    ]]*/;
    var name = /*[[
        ${param.name[0]}+${execInfo.templateName}+'-'+${#dates.createNow()}+'-'+${#locale}
    ]]*/;
</script>

<script th:inline="javascript">

/*<![CDATA[*/

    var username = [[#{test}]];

    var name = [[${param.name[0]}+${execInfo.templateName}+'-'+${#dates.createNow()}+'-'+${#locale}]];

/*]]>*/

</script>

adding code: /* [+…+]*/

var x = 23;
/*[+
var msg = 'Hello, ' + [[${session.user.name}]]; +]*/
var f = function() {
...

removind code: /[- / and /* -]*/

var x = 23;
/*[- */
var msg = 'This is a non-working template'; /* -]*/
var f = function() {
...

14、驗證模板的正確性

<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-4.dtd">
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-transitional-thymeleaf-4.dtd">
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-frameset-thymeleaf-4.dtd">
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml11-thymeleaf-4.dtd">

15、特殊用法展示

<td th:text="${#aggregates.sum(o.orderLines.{purchasePrice * amount})}">23.32</td>

以上表示List orderLines的所有訂單的總價
