本想簡單說一下thymeleaf模板語法,因爲畢竟後邊SpringSecurity用到的語法很少,結果總結起來有點兒多…
關於SpringBoot-thymeleaf模板集成,請跳轉 : SpringBoot-thymeleaf模板集成
先說句有用的廢話:
thymeleaf模板語法,都以th屬性開頭,如:
<span th:text="...">

一,thymeleaf-簡單表達式
1.變量表達式
2.選擇或星號表達式
3.文字國際化表達式
4.URL表達式

1,變量表達式
Thymeleaf模板引擎在進行模板渲染時,還會附帶一個Context存放進行模板渲染的變量,在模板中定義的表達式本質上就是從Context中獲取對應的變量的值
<p>Today is: <span th:text="${day}">2 November 2016</span>.</p>
- 1
假設day的值爲2016年11月2日,那麼渲染結果爲:<p>Today is: 2016年11月2日.</p>。
注意 : 渲染後,模板中span值2 November 2016將被覆蓋

2,選擇(星號)表達式
可以簡單理解爲內層是對外層對象的引用
<div th:object="${session.user}">
<p>Name: <span th:text="*{firstName}">Sebastian</span>.</p>
<p>Surname: <span th:text="*{lastName}">Pepper</span>.</p>
<p>Nationality: <span th:text="*{nationality}">Saturn</span>.</p>
</div>
- 1
- 2
- 3
- 4
- 5
等同於以下方式:
<div>
<p>Name: <span th:text="${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>
- 1
- 2
- 3
- 4
- 5
也可以混用,如下:
<div th:object="${session.user}">
<p>Name: <span th:text="*{firstName}">Sebastian</span>.</p>
<p>Surname: <span th:text="${session.user.lastName}">Pepper</span>.</p>
<p>Nationality: <span th:text="*{nationality}">Saturn</span>.</p>
</div>

- 3
- 4
- 5
如何沒有與th:object結合使用,*{}與${}效果一樣,因爲其範圍自動擴展到context。

3,URL表達式
URL表達式指的是把一個有用的上下文或會話信息添加到URL,這個過程經常被叫做URL重寫。
Thymeleaf對於URL的處理是通過語法@{…}來處理的
<!— 絕對路徑 —>
<!-- 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=${o.id})}">view</a>
<!— 相對路徑 帶參數—>
<!-- Will produce '/gtvg/order/details?orderId=3' (plus rewriting) -->
<a href="details.html" th:href="@{/order/details(orderId=${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>

- 10
Thymeleaf支持相對路徑和絕對路徑
(orderId=${o.id})表示將括號內的內容作爲URL參數處理
@{...}表達式中可以通過{orderId}訪問Context中的orderId變量
@{/order}是Context相關的相對路徑,在渲染時會自動添加上當前Web應用的Context名字,假設context名字爲app,那麼結果應該是/app/order

4,文字國際化表達式
文字國際化表達式允許我們從一個外部文件獲取區域文字信息(.properties)
使用Key-Value方式,還可以提供一組參數(可選).
.properties
#{main.title}
{message.entrycreated(${entryId})}
模板引用:
<table>
<th th:text="#{header.address.city}">...</th>
<th th:text="#{header.address.country}">...</th>
</table>

- 4
二.thymeleaf-字面值
1.文本文字:’one text’, ‘Another one!’,…
2.文字數量:0, 34, 3.0, 12.3,…
3.布爾型常量:true, false
4.空的文字:null
5.文字標記:one, sometext, main,…
三:thymeleaf-文本處理
1.字符串拼接:+
<span th:text="'Welcome to our application, ' + ${user.name} + '!'">
- 1
2.文字替換:|The name is ${name}|
<span th:text="|Welcome to our application, ${user.name}!|">
- 1
相比以上兩種方式都可以實現字符串合併,但是,|…|中只能包含變量表達式${…},不能包含其他常量、條件表達式等。
四.表達基本對象
1.#ctx:上下文對象
2.#vars:上下文變量
3.#locale:上下文語言環境
4.#httpServletRequest:(只有在Web上下文)HttpServletRequest對象
5.#httpSession:(只有在Web上下文)HttpSession對象。
例如:
<span th:text="${#locale.country}">US</span>.
th:text="${#calendars.format(today,'dd MMMM yyyy')}"
- 1
- 2
- 3
五,表達式預處理
表達式預處理,它被定義在_之間:
#{selection.__${sel.code}__}
- 1
${sel.code}將先被執行,結果(假如是AAA)將被看做表達式的一部分被執行
結果#{爲selection.AAA}。
- 1
- 2
- 3
六,thymeleaf運算符
在表達式中可以使用各類算術運算符,例如+, -, *, /, %
th:with="isEven=(${prodStat.count} % 2 == 0)"
- 1
邏輯運算符>, <, <=,>=,==,!=都可以使用
需要注意的是使用 > ,<, >=, <=時需要用它的HTML轉義符(> gt; < lt; >= ge; gte; <= le; lte; == eq; != ne; neq;)
th:if="${prodStat.count} > 1"
th:text="'Execution mode is ' + ( (${execMode} == 'dev')? 'Development' : 'Production')"
- 1
- 2
布爾運算符 and,or
七,thymeleaf循環
數據集合必須是可以遍歷的,使用th:each標籤:
<body>
<h1>Product list</h1>
<table>
<tr>
<th>NAME</th>
<th>PRICE</th>
<th>IN STOCK</th>
</tr>
<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>
</table>
<p>
<a href="../home.html" th:href="@{/}">Return to home</a>
</p>
</body>

- 15

- 17
- 18
- 19
- 20
被循環渲染的元素<tr>中加入th:each標籤
th:each="prod : ${prods}"對集合變量prods進行遍歷,對象prod在循環體中可通過表達式訪問
- 1
- 2
- 3
八,thymeleaf條件求值
1,If/Unless
Thymeleaf中使用th:if和th:unless屬性進行條件判斷
<a th:href="@{/login}" th:unless=${session.user != null}>Login</a>
- 1
th:unless與th:if相反,表達式條件不成立時顯示內容。
2,Switch
多路選擇Switch結構,默認屬性default,用*表示
<div th:switch="${user.role}">
<p th:case="'admin'">User is an administrator</p>
<p th:case="#{roles.manager}">User is a manager</p>
<p th:case="*">User is some other thing</p>
</div>
- 1
- 2
- 3
- 4
- 5
3.If-then-else: (if)?(then):else 三元運算符
三元運算控制class屬性選擇
<tr th:class="${row.even}? 'even' : 'odd'">
- 1
三元運算嵌套
<tr th:class="${</span>row.even}? (${row.first}? 'first' : 'even') : 'odd'">
- 1
還可以省略else部分,當表達式結果爲false,返回null,否則返回’alt’
<tr th:class="${row.even}? 'alt'">
...
</tr>
- 1
- 2
- 3
4.If-then: (if) ? (then) ,省略了else部分,如果條件不成立,返回null
如果第一個表達式的計算結果爲null,則取第二個表達式的結果
<div th:object="${session.user}">
<p>Age: <span th:text="*{age}?: '(no age specified)'">27</span>.</p>
</div>
- 1
- 2
- 3
等效於:
<p>Age: <span th:text="*{age != null}? *{age} : '(no age specified)'">27</span>.</p>
- 1
條件表達式嵌套:
<p>Name: <span th:text="*{firstName} ?: (*{admin} ? 'Admin' : #{default.username})">Sebastian</span>.</p>
- 1
九,Thymeleaf-Utilities
Thymeleaf提供了套Utility對象,內置於Context中,可通過#直接訪問:
- #dates: java.util的實用方法。對象:日期格式、組件提取等.
- #calendars: 類似於#日期,但對於java.util。日曆對象
- #numbers: 格式化數字對象的實用方法。
- #strings:字符串對象的實用方法:包含startsWith,將/附加等。
- #objects: 實用方法的對象。
- #bools: 布爾評價的實用方法。
- #arrays: 數組的實用方法。
- #lists: list集合。
- #sets:set集合。
- #maps: map集合。
- #aggregates: 實用程序方法用於創建聚集在數組或集合.
- #messages: 實用程序方法獲取外部信息內部變量表達式,以同樣的方式,因爲他們將獲得使用# {…}語法
- #ids: 實用程序方法來處理可能重複的id屬性(例如,由於迭代)。
