胸腺安全性没有呈现为HTML

我正在使用Spring.start.io的Spring Boot我有一个问题，我的视图（百叶窗）不会呈现sec:标记到适当的html我的pom.xml文件

我的胸腺模板

的结果是：https：//i.stack.imgur.com/jk9pi.jpg

我到底做错了什么？我什至对角色有智能的智能，我链接了正确的依赖项，也链接了sec xml标签。

您不需要使用sec:扩展程序进行简单的弹簧安全集成。

有条件的块，具体取决于角色：

<div th:if="${#request.isUserInRole('ADMIN')}">
  Za Admina
</div>

打印用户名：

<div th:text="${#request.userPrincipal.name}"></div>

我认为这是由于没有将弹簧安全方言添加到TemplateEngine中而引起的。我不确定您是如何设置WebMvcconfig的，但作为一个例子：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect;
import org.thymeleaf.spring4.SpringTemplateEngine;
import org.thymeleaf.spring4.view.ThymeleafViewResolver;
import org.thymeleaf.templateresolver.ClassLoaderTemplateResolver;
import org.thymeleaf.templateresolver.TemplateResolver;
import org.thymeleaf.templateresolver.UrlTemplateResolver;
@Configuration
@EnableScheduling
@EnableTransactionManagement
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Bean
public TemplateResolver templateResolver() {
    TemplateResolver templateResolver = new ClassLoaderTemplateResolver();
    templateResolver.setPrefix("views/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCacheable(false);
    return templateResolver;
}
@Bean
public UrlTemplateResolver urlTemplateResolver() {
    return new UrlTemplateResolver();
}
@Bean
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(templateResolver());
    templateEngine.addTemplateResolver(urlTemplateResolver());
    templateEngine.addDialect(new SpringSecurityDialect());
    return templateEngine;
}
@Bean
public ViewResolver thymeleafViewResolver() {
    ThymeleafViewResolver vr = new ThymeleafViewResolver();
    vr.setTemplateEngine(templateEngine());
    vr.setCharacterEncoding("UTF-8");
    vr.setOrder(Ordered.HIGHEST_PRECEDENCE);
    return vr;
}

}

问候玛丽安

@Edit：我添加了WebMvcconfig的完整示例。对于此示例，视图将位于资源/视图中，但是您可以按照您想要的方式进行设置。
