java - SAML 元数据条目的签名信任建立失败

Question

为了从远程源获取元数据，我定义了一个 ExtendedMetadataDelegate bean，如下所示:

@Bean
@Qualifier("replyMeta")
public ExtendedMetadataDelegate replyMetadataProvider() throws MetadataProviderException {
    String metadataURL = "https://ststest.mydomain.it/FederationMetadata/2007-06/FederationMetadata.xml";
    final Timer backgroundTaskTimer = new Timer(true);
    HTTPMetadataProvider provider = new HTTPMetadataProvider(
            backgroundTaskTimer, httpClient(), metadataURL);
    provider.setParserPool(parserPool());
    ExtendedMetadataDelegate emd = new ExtendedMetadataDelegate(
            provider, new ExtendedMetadata());
    return emd;
}

为了保证签名信任的建立，我在JDK keystore和application keystore中都添加了相关的key(第二步可能还不够)；尽管如此，运行 webapp 还是会发生错误。

错误通过设置消失:

emd.setMetadataTrustCheck(false); 

...但我想检查使用的元数据。

有没有办法解决这个错误？

更新:

我尝试如下设置ExtendedMetadata，但错误仍然存​​在。

em.setAlias("defaultAlias");
em.setSigningKey("*.mydomain.it (Go Daddy Secure Certification Authority)");

您很可能导入了 HTTPS 证书，但没有导入用于创建签名的证书 - 它们不同。你应该:

1. 使用从元数据中获取的以下内容创建文件 signature.cer:

   -----BEGIN CERTIFICATE-----
   MIIC7jCCAdagAwIBAgIQa+pSaOoDP6ZL3qAi564CxzANBgkqhkiG9w0BAQs
   FADAzMTEwLwYDVQQDEyhBREZTIFNpZ25pbmcgLSBzdHN0ZXN0LXJlcGx5bm

   -----END CERTIFICATE-----
   

2. 将证书导入到您的 samlKeystore.jks 中:

    keytool -importcert -alias adfssigning -keystore samlKeystore.jks -file signature.cer
   

这应该是您所需要的，只需重新启动 Tomcat，您的元数据加载现在应该可以通过了。

如果您包含以下配置 HTTP 客户端的 bean(在 Spring SAML 1.0.0.RELEASE 中可用)，则无需在 JDK 的 cacerts 中包含 HTTPS 证书:

 <bean class="org.springframework.security.saml.trust.httpclient.TLSProtocolConfigurer"/>
