使用Spring Security进行Thymeleaf授权不起作用

Question

我在Spring Boot应用程序中使用Spring Security,似乎Thymeleaf授权无法正常工作.

我有Thymeleaf模板,代码如下:

<div class="container">
    <div class="row" sec:authorize="isAuthenticated()">
        <h2 style="color:green">User is Logged In</h2>
        <p sec:authentication="principal.username">username</p>
    </div>

    <div class="row" sec:authorize="!isAuthenticated()">
        <h2 style="color:red">User is Logged Out</h2>
    </div>

    <div class="row" sec:authorize="hasRole('ROLE_SUPERUSER')">
        <h2>This will only be displayed if authenticated user has role ROLE_SUPERUSER.</h2>
    </div>

    <div class="row" sec:authorize="hasRole('ROLE_ADMIN')">
        <h2>This will only be displayed if authenticated user has role ROLE_ADMIN.</h2>
    </div>

    <div class="row" sec:authorize="hasRole('ROLE_USER')">
        <h2>This will only be displayed if authenticated user has role ROLE_USER.</h2>
    </div>

    <div th:if="${#authorization.expression('hasRole(''ROLE_ADMIN'')')}">
        This will only be displayed if authenticated user has role ROLE_ADMIN.
    </div>

    <div th:if="${#authorization.expr('hasRole(''ROLE_ADMIN'')')}">
        This will only be displayed if authenticated user has role ROLE_ADMIN.
    </div>
</div>

示例来自:https://github.com/thymeleaf/thymeleaf-extras-springsecurity

但是,显示的唯一内容是sec:authorize="isAuthenticated()"和,sec:authorize="!isAuthenticated()"并且无论用户的角色如何,始终都会忽略授权.

我的百里香配置是:

@Configuration
public class ThymeleafConfig {

    @Bean
    public TemplateResolver defaultTemplateResolver() {
        TemplateResolver resolver = new TemplateResolver();
        resolver.setResourceResolver(thymeleafResourceResolver());
        resolver.setPrefix("classpath:/templates/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode("HTML5");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setCacheable(true);
        return resolver;
    }

    @Bean
    public SpringResourceResourceResolver thymeleafResourceResolver() {
        return new SpringResourceResourceResolver();
    }

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

    @Bean
    public ThymeleafViewResolver thymeleafViewResolver(SpringTemplateEngine templateEngine) {
        ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine);
        resolver.setCharacterEncoding("UTF-8");
        resolver.setContentType("text/html");
        resolver.setOrder(Ordered.LOWEST_PRECEDENCE - 5);
        return resolver;
    }

}

我使用以下依赖项thymeleaf-extras-springsecurity4:

<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity4</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>

版本3.0.2.RELEASE根本不起作用,secThymeleaf总是忽略名称空间.
我的Spring Boot版本是1.5.2.RELEASE.

可能是什么原因？

UPDATE.该configure(HttpSecurity http)方法SecurityConfig看起来像:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().ignoringAntMatchers("/h2-console").disable()
            .authorizeRequests()
                .antMatchers("/webjars/**", "/static/**", "/images/**", "/**/favicon.ico").permitAll()
                .antMatchers("/heat/**", "/power/**", "/water/**").permitAll()

            // start allowing h2-console
                .antMatchers("/h2-console/**").permitAll();
            http.csrf().disable();
            http.headers().frameOptions().disable()
            // end allowing h2-console

            .and().authorizeRequests().antMatchers("/info").permitAll()
            .and().authorizeRequests().antMatchers("/users/**").authenticated()
            .and().authorizeRequests().antMatchers("/users/**").hasAnyAuthority("ADMIN", "SUPERUSER")

            .and().formLogin()
                    .loginPage("/login")
                    .permitAll()
            .and()
                    .logout()
                    .permitAll()
                    .deleteCookies("remove")
                    .logoutUrl("/logout")
                    .logoutSuccessUrl("/")
                    .invalidateHttpSession(true)

            .and().exceptionHandling().accessDeniedPage("/access_denied");
}

并且来自的映射IndexController非常简单,它只返回login模板:

@RequestMapping("/login")
public String loginForm() {
    return "login";
}

解决任务的另一种方法是使用此语法来检查角色:

<div class="row" th:if="${#request.isUserInRole('SUPERUSER')}">
    <h2>This will only be displayed if authenticated user has role ROLE_SUPERUSER.</h2>
</div>

它不使用sec命名空间,实际上根本不需要使用thymeleaf-extras-springsecurity4依赖.
