Java AlreadyBuiltException:在生成“springSecurityFilterChain”时已生成此对象

我正在用SpringSecurity开发一个SpringBoot应用程序，但无法以任何方式让它工作

我想使用SpringSecurity5，但现在我甚至不知道我要使用的是什么版本，使用WebFlux也帮不上忙

问题是，当我创建一个扩展WebSecurityConfigureAdapter的类时，Spring将始终抛出org.springframework.security.config.annotation.AlreadyBuiltException:此对象已在org.springframework.beans.factory.BeanCreationException之后生成：创建在类路径资源中定义了名为“springSecurityFilterChain”的bean时出错[org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]：通过工厂方法实例化Bean失败；嵌套异常为org.springframework.beans.beanstantiationException:实例化[javax.servlet.Filter]失败：工厂方法“springSecurityFilterChain”引发异常；嵌套异常为org.springframework.security.config.annotation.AlreadyBuiltException:此对象已生成，我不知道原因。我尝试删除@Configuration注释、@EnableWebSecurity注释，并添加其他注释，如@Order，但添加或删除注释似乎没有帮助

以下是堆栈跟踪：

如何防止Spring创建多个springSecurityFilterChain，以便我的应用程序能够正确运行

当每个实例多次调用HttpSecuritybuild时，就会发生这种情况。配置HttpSecurity时，您不需要调用HttpSecuritybuild，因为spring security会在后台调用它。因此，删除configureHttpSecurity http中的内置应能解决此问题：

@Override
public void configure(HttpSecurity http) throws Exception {
    http.csrf().disable().authorizeRequests()
            .antMatchers("/*/inserir").hasAuthority(ROLE_ULTRA)
            .anyRequest().authenticated()
            .and().formLogin();
}
