spring boot(四)：thymeleaf使用详解

来源：互联网发布：网眼空间绑定域名教程编辑：程序博客网时间：2024/06/17 18:56

thymeleaf模板语法,都以th属性开头,如:

<span th:text="...">1
2

一,thymeleaf-简单表达式

1.变量表达式2.选择或星号表达式3.文字国际化表达式4.URL表达式

1,变量表达式

Thymeleaf模板引擎在进行模板渲染时，还会附带一个Context存放进行模板渲染的变量，在模板中定义的表达式本质上就是从Context中获取对应的变量的值

<p>Today is: <span th:text="${day}">2 November 2016</span>.</p>1
1

假设day的值为2016年11月2日，那么渲染结果为：<p>Today is: 2016年11月2日.</p>。注意 : 渲染后,模板中span值2 November 2016将被覆盖

2,选择(星号)表达式

可以简单理解为内层是对外层对象的引用

<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

等同于以下方式:

<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

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>1

如何没有与th:object结合使用，*{}与${}效果一样，因为其范围自动扩展到context。

3,URL表达式

URL表达式指的是把一个有用的上下文或会话信息添加到URL，这个过程经常被叫做URL重写。
Thymeleaf对于URL的处理是通过语法@{…}来处理的

<!— 绝对路径 —><!-- 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=${o.id})}">view</a><!— 相对路径 带参数—><!-- Will produce '/gtvg/order/details?orderId=3' (plus rewriting) --><a href="details.html" th:href="@{/order/details(orderId=${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>1

Thymeleaf支持相对路径和绝对路径(orderId=${o.id})表示将括号内的内容作为URL参数处理@{...}表达式中可以通过{orderId}访问Context中的orderId变量@{/order}是Context相关的相对路径，在渲染时会自动添加上当前Web应用的Context名字，假设context名字为app，那么结果应该是/app/order

4,文字国际化表达式

文字国际化表达式允许我们从一个外部文件获取区域文字信息(.properties)
使用Key-Value方式，还可以提供一组参数(可选).

.properties

#{main.title}#{message.entrycreated(${entryId})}1
2
1
2

模板引用:

<table>    <th th:text="#{header.address.city}">...</th>    <th th:text="#{header.address.country}">...</th></table>1

二.thymeleaf-字面值

　　1.文本文字：’one text’, ‘Another one!’,…
　　2.文字数量：0, 34, 3.0, 12.3,…
　　3.布尔型常量：true, false
　　4.空的文字：null
　　5.文字标记：one, sometext, main,…
　　

三：thymeleaf-文本处理

1.字符串拼接：+

<span th:text="'Welcome to our application, ' + ${user.name} + '!'">1
1

2.文字替换：|The name is ${name}|

<span th:text="|Welcome to our application, ${user.name}!|">1
1

相比以上两种方式都可以实现字符串合并,但是,|…|中只能包含变量表达式${…}，不能包含其他常量、条件表达式等。

四.表达基本对象

　　1.#ctx:上下文对象

　　2.#vars:上下文变量

　　3.#locale:上下文语言环境

　　4.#httpServletRequest:(只有在Web上下文)HttpServletRequest对象

　　5.#httpSession:(只有在Web上下文)HttpSession对象。

例如:

<span th:text="${#locale.country}">US</span>.th:text="${#calendars.format(today,'dd MMMM yyyy')}"1

五,表达式预处理

表达式预处理，它被定义在_之间：

#{selection.__${sel.code}__}1
1

${sel.code}将先被执行，结果(假如是AAA)将被看做表达式的一部分被执行结果#{为selection.AAA}。

六,thymeleaf运算符

在表达式中可以使用各类算术运算符，例如+, -, *, /, %

th:with="isEven=(${prodStat.count} % 2 == 0)"1
1

逻辑运算符>, <, <=,>=，==,!=都可以使用
需要注意的是使用 > ,<, >=, <=时需要用它的HTML转义符(> gt; < lt; >= ge; gte; <= le; lte; == eq; != ne; neq;)

th:if="${prodStat.count} &gt; 1"th:text="'Execution mode is ' + ( (${execMode} == 'dev')? 'Development' : 'Production')"1
2

布尔运算符 and,or

七,thymeleaf循环

数据集合必须是可以遍历的，使用th:each标签：

<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>1

被循环渲染的元素<tr>中加入th:each标签th:each="prod : ${prods}"对集合变量prods进行遍历，对象prod在循环体中可通过表达式访问

八,thymeleaf条件求值

1,If/Unless

Thymeleaf中使用th:if和th:unless属性进行条件判断

设置标签只有在th:if中条件成立时才显示:

<a th:href="@{/login}" th:unless=${session.user != null}>Login</a>1
1

th:unless与th:if相反，表达式条件不成立时显示内容。

2,Switch

多路选择Switch结构,默认属性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

3.If-then-else: (if)?(then):else 三元运算符

三元运算控制class属性选择

 <tr th:class="${row.even}? 'even' : 'odd'">1
1

三元运算嵌套

<tr th:class="${row.even}? (${row.first}? 'first' : 'even') : 'odd'">1
1

还可以省略else部分，当表达式结果为false，返回null，否则返回’alt’

<tr th:class="${row.even}? 'alt'">    ...</tr>1
2
3
1
2
3

4.If-then: (if) ? (then) ,省略了else部分，如果条件不成立，返回null

如果第一个表达式的计算结果为null，则取第二个表达式的结果

<div th:object="${session.user}">    <p>Age: <span th:text="*{age}?: '(no age specified)'">27</span>.</p></div>1
2
3
1
2
3

等效于：

<p>Age: <span th:text="*{age != null}? *{age} : '(no age specified)'">27</span>.</p>1
1

条件表达式嵌套：

<p>Name: <span th:text="*{firstName} ?: (*{admin} ? 'Admin' : #{default.username})">Sebastian</span>.</p>1
1

九,Thymeleaf-Utilities

Thymeleaf提供了套Utility对象,内置于Context中,可通过#直接访问：

- #dates: java.util的实用方法。对象:日期格式、组件提取等.- #calendars: 类似于#日期,但对于java.util。日历对象- #numbers: 格式化数字对象的实用方法。- #strings:字符串对象的实用方法:包含startsWith,将/附加等。- #objects: 实用方法的对象。- #bools: 布尔评价的实用方法。- #arrays: 数组的实用方法。- #lists: list集合。- #sets:set集合。- #maps: map集合。- #aggregates: 实用程序方法用于创建聚集在数组或集合.- #messages: 实用程序方法获取外部信息内部变量表达式,以同样的方式,因为他们将获得使用# {…}语法- #ids: 实用程序方法来处理可能重复的id属性(例如,由于迭代)。
