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>
