thymeleaf sec：授权在 Spring Boot 中不工作

Posted 2023-02-27

【中文标题】thymeleaf sec：授权在 Spring Boot 中不工作

【英文标题】：thymeleaf sec:authorize not working in spring boot

【发布时间】：2019-08-07 09:23:37

【问题描述】：

我有一个带有 Thymeleaf 和内存身份验证的 Spring MVC 项目。 在我的 html 中，我想显示当前登录的用户并仅在有人登录时显示注销按钮。

这是一个简单的 html，应该显示用户名，但总是显示 Bob 和一个应该只在有人登录时显示的文本，但它总是显示。

知道我做错了什么吗？

这是我的 pom.xml

            <span sec:authentication="name">Bob</span>


        </section>
    </div>
    </div>

和我的安全配置：

package info.climbinggyms.main;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter 

    @Override
    protected void configure(HttpSecurity http) throws Exception 
        http
                .httpBasic()
                .and()
                .authorizeRequests()
                .antMatchers("/admin/**").hasAnyRole("ADMIN","USER")
                .and()
                .csrf().disable().headers().frameOptions().disable()
                .and()
                .formLogin()
                .and()
                .logout();
    
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception 
        auth.inMemoryAuthentication()
                .withUser("bleau83").password("noopbleau83").roles("ADMIN")
                .and()
                .withUser("user").password("noopuser").roles("USER");
    

【参考方案1】：

我将 thymeleaf 安全更新为 springsecurity5，现在它可以工作了

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

【讨论】：

这似乎也对我有用，虽然我不知道为什么。

@bleau83 我遇到了同样的问题。我在我的 html 中定义了 xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity5" 并尝试从 sec:authentication="principal.fullname" 获取值，但我无法显示该值。我只通过[[$#request.userPrincipal.principal.fullName]] 展示它。我该如何解决我的问题？

【参考方案2】：

我也遇到过类似的问题，我的implementation 'org.thymeleaf.extras:thymeleaf-extras-springsecurity5' 完全从build.gradle 中丢失了。

【参考方案3】：

是的，您需要更新到 springsecurity5

thymeleaf-extras-springsecurity5

【讨论】：

这与 bleau83 给出的答案相同。考虑支持现有的答案，而不是重复它。
