如何解决org.springframework.web.util.NestedServletException：请求处理失败；使用 SAML

Question

我正在开发一个通过 IDP 进行身份验证的应用程序，其中插入 ADFS 服务器。
因此它具有一些功能，可以通过访问元数据 URL（如下所示）从程序级别导入 IDP 元数据，并根据服务提供商端进行更新。

我在尝试处理来自 ADFS 服务器 URL 的 SAML 元数据时遇到请求处理异常。

我发现的一些解决方案说 wildfly8 有问题，Wildfly 7+ 和 JBoss 7+ 没问题，但我仍然遇到同样的问题。

服务器：JBoss EAP 7.1.4 GA
Idp 服务器：ADFS 服务器从 url
访问元数据 https://adfs-server/FederationMetadata/2007-06/FederationMetadata.xml

Idp saml 格式可以在这里找到

https://www.samltool.com/idp_metadata.php

adfs-server（假域名）

当尝试读取元数据时，由于下面的代码片段 credentialResolver 未加载并且它为 null

，因此抛出以下内容

 private void initHttpMetadata(String url) throws MetadataProviderException
 {
  httpMetadataProvider = new HTTPMetadataProvider(new Timer(true), new HttpClient(), url);
  httpMetadataProvider.setRequireValidMetadata(true);
  httpMetadataProvider.setParserPool(new BasicParserPool());
  httpMetadataProvider.initialize();
  if (httpMetadataProvider != null)
  {
  entityDescriptor = httpMetadataProvider.getEntityDescriptor(entityId);
  if (entityDescriptor != null)
  {
    ssoDescriptor = 
entityDescriptor.getIDPSSODescriptor(SAMLConstants.SAML20P_NS);
  }
  credentialResolver  = 
 credentialResolverFactory.getInstance(httpMetadataProvider);
}}

异常：

task-48) [] There is no single sign out services to update in metadata url, Please contact idp system administrator

我尝试了以下选项：

org.springframework.web.util.NestedServletException: Request processing failed

org.springframework.web.util.NestedServletException: Handler processing failed

感谢您对此的建议。谢谢

Answer 1

问题是它试图通过 ssl 连接和读取元数据，ADFS 端 SSL 证书和服务提供端 (SP) ssl 证书不受信任，因为不在正确的层次结构中。

所以两台服务器应该使用正确的 SSL 证书相互信任。在这种情况下，我们需要检查在 ADFS 服务器中添加的证书（您可以在 ADFS 管理控制台--> 证书路径中找到该证书）。它根据证书的类型可能是解密证书或令牌签名证书。

例如：

如果服务提供商端证书在证书路径下：

 DigiCert-->root A--> companyRoot--> Machine certificate

如果 ADFS 证书路径：

必须遵循正确的路径，例如：

DigiCert-->RootA-->*.adfs.com
自签名证书不适用于 ADFS。

这就是问题所在，更正证书后，它工作正常，感谢大家的努力，并希望这个答案也能为其他人澄清。
