Thymeleaf

作者:互联网

springboot直接引入

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

非springboot项目使用如下依赖:

<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf</artifactId>
    <version>2.1.4</version>
</dependency>
默认的模板映射路径是:src/main/resources/templates   springboot1.4之后,可以使用thymeleaf3来提高效率,并且解决标签闭合问题,配置方式:
<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <!-- set thymeleaf version -->
    <thymeleaf.version>3.0.0.RELEASE</thymeleaf.version>
    <thymeleaf-layout-dialect.version>2.0.0</thymeleaf-layout-dialect.version>
    <!--set java version-->
    <java.version>1.8</java.version>
</properties>

2.配置thymeleaf视图解析器

这点与springMVC是相类似的:
#thymeleaf start
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
#开发时关闭缓存,不然没法看到实时页面
spring.thymeleaf.cache=false
#thymeleaf end

3.编写模板html

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>hello</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
    <!--/*@thymesVar id="name" type="java.lang.String"*/-->
    <p th:text="'Hello!, ' + ${name} + '!'">3333</p>
</body>
</html>

选择变量表达式

<div th:object="${session.user}">
    <p>Name: <span th:text="*{firstName}">Sebastian</span>.</p>
    <p>Surname: <span th:text="*{lastName}">Pepper</span>.</p>
    <p>Nationality: <span th:text={nationality}">Saturn</span>.</p>
</div>
等价于
<div>
    <p>Name: <span th:text="${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>

链接表达式

<!-- 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>
<a href="details.html" th:href="@{order/{orderId}/details(orderId=${o.id})}">Content路径,默认访问static下的order文件夹</a>
条件  if/unless    使用th:if和th:unless属性进行条件判断,th:unless于th:if恰好相反,只有表达式中的条件不成立,才会显示其内容。
<a th:href="@{/login}" th:unless=${session.user != null}>Login</a>
   switch
<div th:switch="${user.role}">
  <p th:case="'admin'">User is an administrator</p>
  <p th:case="#{roles.manager}">User is a manager</p>
  <p th:case="*">User is some other thing</p>
</div>
循环 通过th:each  
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>hello</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
    <!-- 不存在则忽略,显示hello null!(可以通过默认值进行设置)-->
    <p th:text="'Hello ' + (${name}?:'admin')">3333</p>
    <table>
        <tr>
            <th>ID</th>
            <th>NAME</th>
            <th>AGE</th>
        </tr>
        <tr th:each="emp : ${empList}">
            <td th:text="${emp.id}">1</td>
            <td th:text="${emp.name}">海</td>
            <td th:text="${emp.age}">18</td>
        </tr>
    </table>
</body>
</html>
