StackOverflowError 试图在 Spring WebSecurityConfigurerAdapter 中公开 AuthenticationManager

Question

我试图通过扩展 WebSecurityConfigurerAdapter 来创建一个 Spring Security 配置，基本上是这样的：

@EnableWebSecurity
@Configuration
public class StackOverflowSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.authenticationProvider(myUsernamePasswordProvider());
        auth.authenticationProvider(mySecurityTokenProvider());

        super.configure(auth);
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManager() throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    public MyPreAuthenticatedProcessingFilter myAuthenticationFilter() throws Exception {
        MyPreAuthenticatedProcessingFilter myAuthenticationFilter = new MyPreAuthenticatedProcessingFilter();
        myAuthenticationFilter.setAuthenticationManager(authenticationManager());

        return myAuthenticationFilter;
    }

}

我看到了这个：

我已尝试更改我能想到的所有方法以正确暴露 AuthenticationManager 而不会出现 StackOverflow 错误，但我仍然卡住了。我发现的唯一一件事是这个缺陷，https://github.com/spring-projects/spring-security/issues/2732，在 Spring Security 中，当“一个无效的配置试图在没有配置身份验证时将 AuthenticationManager 公开为 Bean”时，有人看到了同样的问题。不幸的是，我不知道这到底意味着什么或如何解决这个问题。

这个 Spring Security 配置在 Spring XML 配置中工作，这是我迁移到 Spring Java Config 的尝试。有没有更好的方法来配置我的 Spring Security 和/或将 AuthenticationManager 暴露给我的自定义身份验证过滤器？

Answer 1

当您配置具有相同实例的父身份验证提供程序时，也会发生此（类似症状）问题。即：

@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth
            // next line can cause same stack overflow in case of non-existent user tries login.
            //.parentAuthenticationManager(authenticationManagerBean())
            .userDetailsService(customUserDetailsService)
            .passwordEncoder(passwordEncoder())
            .userDetailsPasswordManager(customUserDetailsService);
    super.configure(auth);
}

我终于弄清楚了这个问题。问题是我覆盖了错误的方法。我做到了：

@Override
@Bean
public AuthenticationManager authenticationManager() throws Exception {
    return super.authenticationManagerBean();
}

代替：

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

我最终覆盖了一个类似但不正确的方法。 authenticationManager() 方法用于对 AuthenticationManager 进行一些配置，authenticationManagerBean() 用于将 AuthenticationManager 公开为可以自动装配和使用的 Spring Bean。做我所做的会导致必要的配置不会发生，而是以导致堆栈溢出的方式链接 AuthenticationManager。
