解决thymeleaf layout布局不生效 - 敬YES

今天使用thymeleaf layout布局时总是不生效，特此把解决问题的步骤和几个关键点记录下来备忘。

一、检查依赖

1.thymeleaf必备maven依赖：

<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf</artifactId>
    <version>${thymeleaf.version}</version>
</dependency>
<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf-spring4</artifactId>
    <version>${thymeleaf.version}</version>
</dependency>

2.如果使用layout布局，还需要添加：

<dependency>
    <groupId>nz.net.ultraq.thymeleaf</groupId>
    <artifactId>thymeleaf-layout-dialect</artifactId>
    <version>2.2.2</version>
</dependency>

二、配置视图引擎

1.配置thymeleaf作为视图引擎

<!-- Thymeleaf View Resolver - implementation of Spring's ViewResolver interface -->
<bean id="viewResolver" class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
    <property name="characterEncoding" value="UTF-8" />
</bean>
 
<!-- Thymeleaf Template Engine (Spring4-specific version) -->
<bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
    <property name="templateResolvers">
        <set>
            <ref bean="templateResolver" />
        </set>
    </property>
</bean>
 
<!-- Thymeleaf Template Resolver -->
<bean id="templateResolver" class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver">
    <property name="prefix" value="/WEB-INF/templates/" />
    <property name="templateMode" value="HTML" />
    <property name="suffix" value=".html"></property>
    <property name="characterEncoding" value="UTF-8"></property>
</bean>

2.使用layout还需要在templateEngine添加如下节点：

<bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
    ……
    <property name="additionalDialects">
        <set>
            <bean class="nz.net.ultraq.thymeleaf.LayoutDialect"/>
        </set>
    </property>
</bean>

三、页面

task/layout.html

<!DOCTYPE html>
<html lang="en" xmlns:layout="http://www.thymeleaf.org">
<head>
    <meta charset="utf-8">
    <title>mysite</title>
</head>
<body>
<div class="container">
    <div class="row">
        <div class="span3" th:insert="fragments/menu::menu"></div>
        <div class="span9" layout:fragment="content"></div>
    </div>
</div>
</body>
</html>

index.html

<!DOCTYPE html>
<html lang="en" layout:decorator="task/layout">
<head>
    <meta charset="utf-8">
    <title>index</title>
</head>
<body>
<div layout:fragment="content">
        <h1>
            Welcome!
        </h1>    
</div>
</body>
</html>

三、版本号

如果检查了以上几项还是没问题，最后还有一点值得注意的，就是thymeleaf和thymeleaf-layout-dialect的版本。

我最后就是调整了maven依赖的版本号，终于成功了。
