spring - Keycloak Spring Boot 适配器和匿名资源

Question

我无法让 Keycloak 跳过对公共(public)资源路径的授权检查。

我们正在使用 Spring Boot Keycloak 适配器。

我们尝试了以下解决方案:

未在应用程序属性中使用安全约束指定路径(“/static/*”没有映射)

以下使用“公共(public)”

    keycloak.security-constraints[10].securityCollections[0].name=public
    keycloak.security-constraints[10].securityCollections[0].patterns[0]=/static/*

在 SecurityConfig.configure()

http.authorizeRequests().antMatchers("/static/**").permitAll()

阅读有关使用策略执行器的信息，但除了使用策略执行器配置之外，没有关于使用 Spring Boot 执行此操作的说明。我不知道在哪里指定，因为我们没有 keycloak.json 文件。

上面的一切总是导致:

Answer 1

其他帖子提到调用 web.ignoring()...，但我覆盖了没有忽略方法的 configure(HttpSecurity) 方法。

我终于意识到我可以覆盖这两种配置方法(HttpSecurity 和 WebSecurity)来实现这一点。

public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/static/*");
}

如果我们可以在应用程序属性文件中使用 keycloak 参数指定匿名访问，那就太好了，但这是可行的。
