我正在尝试找出 thymeleaf 模板中的 Spring 安全注释。我添加了依赖项:

    <dependency>
        <groupId>org.thymeleaf</groupId>
        <artifactId>thymeleaf</artifactId>
        <version>3.0.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity3</artifactId>
        <version>3.0.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.thymeleaf</groupId>
        <artifactId>thymeleaf-spring4</artifactId>
        <version>3.0.1.RELEASE</version>
    </dependency>

这是我的配置:

@Configuration
@EnableWebMvc
@ComponentScan(basePackages={"web"})
public class WebConfig extends WebMvcConfigurerAdapter{

    @Bean
    public MultipartResolver multipartResolver() throws IOException {
        return new CommonsMultipartResolver();
    }

    //THYMELEAF CONFIG

    @Bean
    public ITemplateResolver templateResolver() {
        SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
        templateResolver.setPrefix("/WEB-INF/templates/");
        templateResolver.setSuffix(".html");
        templateResolver.setTemplateMode("HTML5");
    return templateResolver;
    }

    @Bean    
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());
        templateEngine.addDialect(new SpringSecurityDialect());
    return templateEngine;
    }

    @Bean
    public ViewResolver viewResolver(){
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver(); 
        viewResolver.setTemplateEngine(templateEngine());
        return viewResolver;
    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer){
        configurer.enable();
    }

    @Override
    public void addResourceHandlers(final ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

}

在我看来，我有:

<html
    xmlns="http//www.w3.org/1999/xhtml"
    xmlns:th="http://www.thymeleaf.org"
    xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
    ...
    <div sec:authorize="hasRole('ROLE_USER')">
      This content is only shown to users.
    </div>

当我尝试加载此 View 时，我得到:

如何处理这个问题？请提供任何帮助，干杯。

最佳答案

您必须添加spring-security-web

<!-- https://mvnrepository.com/artifact/org.springframework.security/spring-security-web -->
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version><Your_spring_version></version>
</dependency>

作为 pom.xml 的依赖项

它仅适用于 3.2.9 之前的 spring 版本。缺少的类在 spring 3.2.9 中已弃用。所以我猜它在 spring 4 中被删除了，所以你必须更改为旧的 spring 版本或需要该类的较新版本的库。

编辑

因为你使用的是 spring 4，所以你必须更改

<!-- https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity3</artifactId>
    <version>3.0.0.RELEASE</version>
</dependency>

到

<!-- https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity4</artifactId>
    <version>3.0.0.RELEASE</version>
</dependency>
