java - 使用 ${#authentication.name} 的 Spring boot + Security + Thymeleaf 错误

尽管我已经登录，但我收到“org.springframework.expression.spel.SpelEvaluationException 无法在 null 上找到属性或字段“名称””。我已经尝试过更改我的 pom 依赖项的版本，但它不起作用。这是我的实际配置。

}

}

MvcConfig

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {

@Bean
@Description("Thymeleaf template resolver serving HTML 5")
public ClassLoaderTemplateResolver templateResolver() {
    ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
    templateResolver.setPrefix("templates/");
    templateResolver.setCacheable(false);
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    return templateResolver;
}

@Bean
@Description("Thymeleaf template engine with Spring integration")
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(new UrlTemplateResolver());
    templateEngine.setTemplateResolver(templateResolver());
    return templateEngine;
}


@Bean
@Description("Thymeleaf view resolver")
public ViewResolver viewResolver() {
    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(templateEngine());
    viewResolver.setCharacterEncoding("UTF-8");
    return viewResolver;
}

}

知道为什么我不能使用 ${#authentication.name} 吗？我尝试了几种方法，但没有任何效果。我也尝试过使用 sec:authentication="name"，但那个也不起作用。

更新

详细的堆栈跟踪。
