我的应用程序有一个安全配置，可通过验证用户身份LDAP。效果很好，但现在我想添加另一个AuthenticationProvider，对尝试进行身份验证的用户进行更多检查。因此，我尝试添加一个DbAuthenticationProvider（出于测试目的）始终拒绝访问。因此，当我尝试使用我的域帐户（适用于activeDirectoryLdapAuthenticationProvider）登录时，由于第二个提供程序的身份验证失败，因此无法访问该页面。

为了实现此目标，我使用了以下代码：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Value("${ad.domain}")
    private String AD_DOMAIN;

    @Value("${ad.url}")
    private String AD_URL;

    @Autowired
    UserRoleComponent userRoleComponent;

    @Autowired
    DbAuthenticationProvider dbAuthenticationProvider;

    private final Logger logger = LoggerFactory.getLogger(WebSecurityConfig.class);

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        this.logger.info("Verify logging level");
        http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin()
                .successHandler(new CustomAuthenticationSuccessHandler()).and().httpBasic().and().logout()
                .logoutUrl("/logout").invalidateHttpSession(true).deleteCookies("JSESSIONID");
        http.formLogin().defaultSuccessUrl("/", true);
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(activeDirectoryLdapAuthenticationProvider());
        auth.authenticationProvider(dbAuthenticationProvider);
    }

    @Bean
    public AuthenticationManager authenticationManager() {
        return new ProviderManager(Arrays.asList(activeDirectoryLdapAuthenticationProvider(), dbAuthenticationProvider));
    }

    @Bean
    public AuthenticationProvider activeDirectoryLdapAuthenticationProvider() {
        ActiveDirectoryLdapAuthenticationProvider provider = new ActiveDirectoryLdapAuthenticationProvider(AD_DOMAIN,
                AD_URL);
        provider.setConvertSubErrorCodesToExceptions(true);
        provider.setUseAuthenticationRequestCredentials(true);
        return provider;
    }
}

这是我的DbAuthenticationProvider：

@Component
public class DbAuthenticationProvider implements AuthenticationProvider {

    Logger logger = LoggerFactory.getLogger(DbAuthenticationProvider.class);

    @Override
    public Authentication authenticate(Authentication auth) throws AuthenticationException {
        auth.setAuthenticated(false);
        this.logger.info("Got initialized");
        return auth;
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return true;
    }

}

可悲的是，我能够登录（访问没有像我预期的那样被拒绝）。我错过了什么吗？
