Question

我试图仅在允许用户角色的情况下显示链接。但是链接不会被隐藏，并且所有角色都可以显示。

在这里看到了很多类似的查询，但没有一个解决方案在起作用。请告知我所缺少的。

配置。

@Configuration
@EnableWebSecurity
public class SecConfig extends WebSecurityConfigurerAdapter{

    private final String USER = "USER";
    private final String ADMIN = "ADMIN";

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/").hasAnyRole(USER, ADMIN)
                .antMatchers("/closed").hasRole(ADMIN).and()
                .formLogin().defaultSuccessUrl("/");
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("jane").password(passwordEncoder().encode("qwe")).roles(ADMIN, USER).and()
                .withUser("john").password(passwordEncoder().encode("qwe")).roles(USER);
    }

    @Bean
    public BCryptPasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }
}

HTML

<a th:href="@{/closed}">Go to closed</a>

<br/><br/>

<form th:action="@{/logout}" method="post">
    <input type="submit" value="Log out">
</form>

<br/>

<h2>Welcome</h2>
<p>Spring Security Thymeleaf</p>
<div sec:authorize="hasRole('USER')">Text visible to user.</div>
<div sec:authorize="hasRole('ADMIN')">Text visible to admin.</div>
<div sec:authorize="isAuthenticated()">
    Text visible only to authenticated users.
</div>
Authenticated username:
<div sec:authentication="name"></div>
Authenticated user roles:
<div sec:authentication="principal.authorities"></div>

即使Jane没有管理员权限，上面的所有内容也会显示。另外，甚至她的角色和用户名也不会显示。

我还尝试了如下配置方言，这没有什么区别。

@Configuration
public class LeafConfig {

    @Bean
    public SpringSecurityDialect springSecurityDialect(){
        return new SpringSecurityDialect();
    }
}

以下是Jane或John显示的内容。没什么区别：

Welcome
Spring Security Thymeleaf

Text visible to user.
Text visible to admin.
Text visible only to authenticated users.
Authenticated username:
Authenticated user roles:

Answer 1

由于您正在使用Spring Security Extras，因此可以代替sec:authorization尝试使用${#authorization.expression('hasRole(''ROLE_ADMIN'')'}。例如。

<div th:if="${#authorization.expression('hasRole(''USER'')'}">Text visible to user.</div>
<div th:if="${#authorization.expression('hasRole(''ADMIN'')'}">Text visible to admin.</div>
<div th:if="${#authorization.expression('isAuthenticated()')}">
    Text visible only to authenticated users.
</div>

如果您使用权限而不是角色，则以下代码可以解决问题。

<div th:if="${#authorization.expression('hasAuthority(''ADMIN'')')}">ADMIN</div>
     <div th:if="${#authorization.expression('hasAuthority(''USER'')')}">USER</div>
     <div th:if="${#authorization.expression('isAuthenticated()')}">
         Text visible only to authenticated users.
     </div>
</div>

关于配置，请在org.thymeleaf.extras中将thymeleaf-extras-springsecurity5的{{1}}更改为.pom，然后需要在配置中添加Spring Dialect @Bean。

POM

<dependencies>
    ...
    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity5</artifactId>
    </dependency>
    ...
</dependencies>

LeafConfig

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.thymeleaf.extras.springsecurity5.dialect.SpringSecurityDialect;

@Configuration
public class LeafConfig {

    @Bean
    public SpringSecurityDialect springSecurityDialect(){
        return new SpringSecurityDialect();
    }

}

这些更改之后，一切都会按预期进行。

Answer 2

您应该按如下方式使用它：

<sec:authorize access="hasRole('ADMIN')">
  <div>
    This content will only be visible to users who have
    the "ADMIN" authority in their list of GrantedAuthority's.
  </div>
</sec:authorize>

无法根据安全性隐藏链接
