spring - 连接多种认证机制 Spring Boot Security

Question

我的应用程序有一个安全配置，通过 LDAP 对用户进行身份验证.这很有效，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。所以我尝试添加一个 DbAuthenticationProvider (出于测试目的)总是拒绝访问。因此，当我尝试使用我的域帐户(适用于 activeDirectoryLdapAuthenticationProvider )登录时，我无法访问该页面，因为第二个提供程序未通过身份验证。

为了实现这个目标，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;
    }

}

遗憾的是，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？

Spring 不会使用多个 AuthenticationProvider验证请求，所以第一个(在 ArrayList 中)AuthenticationProvider支持Authentication对象并成功验证请求将是唯一使用的。在你的情况下是 activeDirectoryLdapAuthenticationProvider .

而不是使用 ActiveDirectoryLdapAuthenticationProvider ，您可以使用委托(delegate)给 LDAP 的自定义 AuthenticationProvider 并执行其他检查:

    CustomerAuthenticationProvider implements AuthenticationProvider{
        privtae ActiveDirectoryLdapAuthenticationProvider  delegate; // add additional methods to initialize delegate during your configuration

          @Override
         public Authentication authenticate(Authentication auth) throws 
             AuthenticationException {
            Authentication  authentication= delegate.authenticate(auth);
            additionalChecks(authentication);
           return auth;
           }


          @Override
          public boolean supports(Class<?> authentication) {
            return UsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication);
          }

        public void additionalCheck(Authentication authentication){
               // throw AuthenticationException when it's not allowed
        }

    }
