Thymeleaf Spring Security集成秒：授权不起作用

Question

我正在使用带Spring security的Thymeleaf模板引擎。为了使用sec:authorize功能，我还使用了Thymeleaf-Spring Security集成模块，但由于某些原因，它不起作用。我没有收到任何错误，但是html div块中的所有代码都会被执行，无论用户扮演哪个角色。

例如，当我以员工身份登录时，我也会看到“去领导”和“去系统”按钮，但我不想让员工看到这些按钮。

这是我的pom。xml文件

Answer 1

问题解决了，我胸腺叶配置中的某些东西正在干扰。

    @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.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;
    }

Answer 2

以下依赖项应该可以解决此问题

<dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity5</artifactId>
        <version>3.0.4.RELEASE</version>
</dependency>

还可以从更改XML命名空间

xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity5"

到

xmlns:sec="http://www.thymeleaf.org/extras/spring-security"
