我将Thymeleaf从2.1版升级到3.0 BETA-1。新的Thymeleaf需要java配置，所以我将我的xml配置重写为java。一切正常，期待布局方言。我不明白为什么。
@Configuration
@EnableWebMvc
@ComponentScan
public class ThymeleafConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware {
private ApplicationContext applicationContext;
public void setApplicationContext(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Bean(name = "templateViewResolver")
public ViewResolver viewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
resolver.setCharacterEncoding("UTF-8");
resolver.setContentType("text/html; charset=UTF-8");
return resolver;
}
@Bean(name = "templateEngine")
public TemplateEngine templateEngine() {
TemplateEngine engine = new TemplateEngine();
engine.setTemplateResolver(templateResolver());
engine.addDialect(new SpringSecurityDialect());
engine.addDialect(new LayoutDialect()); //On this line I get Exception
return engine;
}
@Bean(name = "templateResolver")
public ITemplateResolver templateResolver() {
SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("/views/");
resolver.setSuffix(".html");
resolver.setTemplateMode("HTML5");
resolver.setCharacterEncoding("UTF-8");
resolver.setCacheable(false);
return resolver;
}
@Bean(name = "thymeleafViewResolver")
public AjaxThymeleafViewResolver thymeleafViewResolver() {
AjaxThymeleafViewResolver thymeleafViewResolver = new AjaxThymeleafViewResolver(); // web flow ajax
thymeleafViewResolver.setViewClass(FlowAjaxThymeleafView.class); // web flow + thymeleaf ajax
thymeleafViewResolver.setTemplateEngine(templateEngine());
thymeleafViewResolver.setCharacterEncoding("UTF-8");
return thymeleafViewResolver;
}
}
（我知道在这种情况下这个bean的名字是没用的） 我也使用Spring Web Flow
<bean class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator"
id="mvcViewFactoryCreator">
<property name="viewResolvers" ref="thymeleafViewResolver"/>
</bean>
所以我将百里叶视图解析器设置为此。

Thymeleaf 3尚未提供Thymeleaf布局方言
答案 1 :(得分：1)
将其添加到pom.xml：
<dependency>
<groupId>nz.net.ultraq.thymeleaf</groupId>
<artifactId>thymeleaf-layout-dialect</artifactId>
<version>2.1.2</version>
</dependency>
答案 2 :(得分：0)
这个完全相同的错误是对我造成的，因为我忘记删除 thymeleaf-extras-springsecurity5 依赖项。从 pom.xml 中删除 spring security 依赖项后。
