具有错误的Active Directory Ldap凭据的会话/ Redis序列化错误的Spring启动

问题描述 投票：6回答：2

嗨，我是Spring和Java的新手，我正在尝试实现本教程中描述的网关认证服务器https://spring.io/guides/tutorials/spring-security-and-angular-js/

我得到了一切工作，然后尝试对我们公司的Ldap服务器实施身份验证。如果我使用有效的用户名和密码，它可以工作。当我使用无效凭据时，应用程序错误。

我没有工作，所以我没有确切的错误，但它返回一个ldap错误（com.sun.jndi.ldap.LdapCtx），Redis正在尝试序列化它。

我的配置中是否缺少某些内容。根据我的阅读，我认为我应该寻找一种方法来包装/扩展类并实现Serializable，但我不确定使用Spring Boot执行此操作的方法最少。

任何帮助是极大的赞赏。

谢谢，

Mike Kowalski

PS我一直在动态语言和框架工作到现在为止（Javascript / Node，Php / Laravel）

以下是我认为安全配置的相关部分：

@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http
      .formLogin()
      .defaultSuccessUrl("/")
      .loginPage("/login")
      .permitAll()
      .and()
      .logout()
      .logoutSuccessUrl("/logout")
      .permitAll();


    http
      .authorizeRequests()
        .antMatchers("/login").permitAll()
        .anyRequest().authenticated()
    .and()
      .csrf().csrfTokenRepository(csrfTokenRepository())
    .and()
      .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
  }

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

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

   @Bean
   public AuthenticationProvider activeDirectoryLdapAuthenticationProvider() {
  ActiveDirectoryLdapAuthenticationProvider provider = new     ActiveDirectoryLdapAuthenticationProvider(
    "XXX.XXX", "ldaps://XXX.XXX:636");
      provider.setConvertSubErrorCodesToExceptions(true);
      provider.setUseAuthenticationRequestCredentials(true);
      return provider;
   }

  private Filter csrfHeaderFilter() {
    return new OncePerRequestFilter() {
      @Override
      protected void doFilterInternal(
        HttpServletRequest request,
        HttpServletResponse response, 
        FilterChain filterChain
      ) throws ServletException, IOException 
      {
        CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class
            .getName());
        if (csrf != null) {
          Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
          String token = csrf.getToken();
          if (cookie == null || token != null
              && !token.equals(cookie.getValue())) {
            cookie = new Cookie("XSRF-TOKEN", token);
            cookie.setPath("/");
            response.addCookie(cookie);
          }
        }
        filterChain.doFilter(request, response);
      }
    };
  }

  private CsrfTokenRepository csrfTokenRepository() {
    HttpSessionCsrfTokenRepository repository = new     HttpSessionCsrfTokenRepository();
    repository.setHeaderName("X-XSRF-TOKEN");
    return repository;
  }

}

以下是使用无效凭据的错误的一部分：

我找到了解决这个问题的方法。我愿意接受任何改进答案的建议。

解决方案不完整，因为我需要在序列化失败时专门查看com.sun.jndi.ldap.LdapCtx类型，因此我可以处理该特定情况并将SerializationException抛给其他所有情况。但我认为一般的想法可能对任何被封锁的人都有用。

现在，当使用无效凭证（例如，错误用户名或密码不正确）时，应用程序将返回登录页面而不是炸毁:)

我添加了一些RedisConfiguration来替换Spring Session正在使用的RedisTemplate。

import com.gateway.utils.LdapFailAwareRedisObjectSerializer;

@Configuration
public class RedisConfiguration {

  @Primary
  @Bean
  public RedisTemplate<String,ExpiringSession> redisTemplate(RedisConnectionFactory connectionFactory) {
    RedisTemplate<String, ExpiringSession> template = new RedisTemplate<String, ExpiringSession>();

    template.setKeySerializer(new StringRedisSerializer());
    template.setHashKeySerializer(new StringRedisSerializer());
    template.setHashValueSerializer(new LdapFailAwareRedisObjectSerializer());

    template.setConnectionFactory(connectionFactory);
    return template;
  }
}

这是我对RedisSerializer<Object>的实现（LdapFailAwareRedisObjectSerializer来自here）

public class LdapFailAwareRedisObjectSerializer implements RedisSerializer<Object> {

  private Converter<Object, byte[]> serializer = new SerializingConverter();
  private Converter<byte[], Object> deserializer = new DeserializingConverter();

  static final byte[] EMPTY_ARRAY = new byte[0];

  public Object deserialize(byte[] bytes) {
    if (isEmpty(bytes)) {
      return null;
    }

    try {
      return deserializer.convert(bytes);
    } catch (Exception ex) {
      throw new SerializationException("Cannot deserialize", ex);
    }
  }

  public byte[] serialize(Object object) {
    if (object == null) {
      return EMPTY_ARRAY;
    }

    try {
      return serializer.convert(object);
    } catch (Exception ex) {
      return EMPTY_ARRAY;
      //TODO add logic here to only return EMPTY_ARRAY for known conditions
      // else throw the SerializationException
      // throw new SerializationException("Cannot serialize", ex);
    }
  }

  private boolean isEmpty(byte[] data) {
    return (data == null || data.length == 0);
  }
}

在使用org.springframework.core.serializer.support.DeserializingConverter和org.springframework.core.serializer.support.SerializingConverter类之后，这对我来说很好用。

/**
 * @author Meron Abraha 12/18/17
 */

public class CustomRedisSerializer implements RedisSerializer<Object> {

private Converter<Object, byte[]> serializer = new SerializingConverter();
private Converter<byte[], Object> deserializer = new DeserializingConverter();

static final byte[] EMPTY_ARRAY = new byte[0];

public Object deserialize(byte[] bytes) {
    if (isEmpty(bytes)) {
        return null;
    }

    try {
        return deserializer.convert(bytes);
    } catch (Exception ex) {
        throw new SerializationException("Cannot deserialize", ex);
    }
}

public byte[] serialize(Object object) {
    if (object == null) {
        return EMPTY_ARRAY;
    }

    try {
        return serializer.convert(object);
    } catch (Exception ex) {
        return EMPTY_ARRAY;

    }
}

private boolean isEmpty(byte[] data) {
    return (data == null || data.length == 0);
}
}
