为什么Spring Security 从KeyClope配置中抛出异常“filterorderregistration.getorder为null”？

我遵循了关于KeyClope和spring boot的教程，配置如下：

@KeycloakConfiguration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class KeycloakConfig extends KeycloakWebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(
        AuthenticationManagerBuilder auth) throws Exception {

        KeycloakAuthenticationProvider keycloakAuthenticationProvider
            = keycloakAuthenticationProvider();
        keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(
            new SimpleAuthorityMapper());
        auth.authenticationProvider(keycloakAuthenticationProvider);
    }

    @Bean
    public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }

    @Bean
    @Override
    protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.authorizeRequests()
            .antMatchers("/visitor").hasRole("visitor")
            .antMatchers("/admin").hasRole("admin")
            .anyRequest()
            .permitAll();
    }

}

application.properties：

keycloak.realm=social-media
keycloak.resource=spring-boot-app
keycloak.auth-server-url=http://localhost:8180/auth
keycloak.ssl-required=external
keycloak.public-client=true
keycloak.principal-attribute=preferred_username
keycloak.use-resource-role-mappings=true

pom.xml中包含Spring Security 和KeyClope spring启动程序。当我运行它时，会出现以下异常：

我知道这个异常来自configure方法super.configure（http），而keydeposeWebSecurityConfigureAdapter扩展了WebSecurityConfigureAdapter，我查看了httpsecurity方法，但我无法找出异常的原因。任何帮助都将不胜感激！

这个问题是在SpringSecurity的5.5.0版本中引入的。之所以会发生这种情况，是因为Key斗篷连续添加了两个过滤器，如下所示：

@Override
protected void configure(HttpSecurity http) throws Exception {
        http
                ...
                .addFilterAfter(keycloakSecurityContextRequestFilter(), SecurityContextHolderAwareRequestFilter.class)
                .addFilterAfter(keycloakAuthenticatedActionsRequestFilter(), KeycloakSecurityContextRequestFilter.class)
                ...
}

现在有一个bug，自定义过滤器顺序没有被持久化，从而导致 NullPointerException 尝试相对于最近添加的另一个自定义筛选器添加筛选器时。
我建议您现在使用较低版本的spring boot，如 2.4.x 直到github中的问题得到解决。
