我最近实现了一个Spring SAML解决方案,该解决方案允许客户向服务注册其IdP元数据,并使用其SAML身份验证来访问我的SP。
IdP 元数据存储为数据库条目,作为自定义 AbstractReloadingMetadataProvider 实现的一部分,如下所示:
public class DbIdpMetadataProvider extends AbstractReloadingMetadataProvider {
...
@Override
protected byte[] fetchMetadata() throws MetadataProviderException {
IdpProviderData provider = null; // DAO of IdP metadata in DB
try {
log.info("Attempting to retrieve DB provider data for entity: " + entityId);
provider = dbService.getIdpByEntityId(entityId);
// verify that we have a provider
if ( null != provider) {
// get last update time recorded in DB
DateTime lastUpdate = getLastUpdate();
log.info("Performing refresh of Metadata Provider XML by reading from database");
String metadataBody = provider.getMetadataBody();
emitChangeEvent();
return metadataBody.getBytes();
}
// if no provider, throw an exception as this metadata provider instance is invalid
else {
log.error("IdP Provider could not be found for EntityId: " + entityId );
throw new MetadataProviderException("Metadata could not be found for String entity: " + entityId);
}
}
catch(Exception e) {
log.error("Failed to query database for provider entity: " + entityId);
throw new MetadataProviderException("Failed to query database for provider entity: " + entityId, e);
}
}
当元数据更新时,我将元数据XML保存到数据库中,并从CachingMetadataManager中删除元数据提供程序的前一个实例。然后,我将证书从元数据导入到本地密钥库中,并将一个新的元数据提供者实例添加到CachingMetadataManager:
@Autowired
private MetadataManager metadataManager;
...
/**
* Update our existing IdP metadata provider with new XML and other information
*/
public void updateIdpMetadata(IdPRegistrationData _data) throws RequiredDataException, NotFoundException, SystemException {
IdpProviderData provider;
XMLObject xml;
String metadataXml;
EntityDescriptor entity;
String entityId;
try {
// validation
validateIdpRegistrationData(_data);
//ensure our top level DOM element is the IDPSSO entity descriptor, removing all other metadata
xml = parseMetadataXml(_data.getMetadataXml());
entity = getIDPSSOParentEntityDescriptor(xml);
entityId = entity.getEntityID();
metadataXml = serialize(entity);
// get our provider Data
provider = getIdpByAccountSysid(_data.getAccountSysid());
if ( null == provider) {
throw new NotFoundException(NotFoundExceptionType.ACCOUNT);
}
// update our provider
provider.setEntityId(entityId);
provider.setMetadataBody(metadataXml);
// save data in database
metadataStoreDao.saveAndFlush(provider);
keystoreMgr.importMetadataCertificates(xml, provider.getUrlContext());
// remove existing provider from metadata store
removeDelegateFromManager(entityId);
// reintroduce delegate to manager
loadIdpMetadata(provider);
}
catch(NotFoundException e) {
log.error("No previous version of IDP registration metadata found to update.",e);
throw (e);
}
catch (MetadataProviderException e){
log.error("Failed to update Keystore and Signing algorithm of IdP Metadata.",e);
throw new SystemException("Failed to update certificates.");
}
catch(RequiredDataException e) {
log.error("Missing required data for update.",e);
throw(e);
}
}
/**
* Remove the metadata provider from our manager
*/
private void removeDelegateFromManager( String _entityId ) throws MetadataProviderException {
ExtendedMetadataDelegate delegate;
DbIdpMetadataProvider provider;
delegate = findMetadataDelegate(_entityId);
if( null == delegate){
log.error("Failed to find Delegate in metadata manager for Entity ID: " + _entityId );
return;
}
metadataManager.removeMetadataProvider(delegate);
provider = (DbIdpMetadataProvider)delegate.getDelegate();
provider.destroy();
metadataManager.setRefreshRequired(true);
metadataManager.refreshMetadata();
}
/**
* load our provider data to a metadata provider object
*/
private void loadIdpMetadata(IdpProviderData _providerData) throws MetadataProviderException {
DbIdpMetadataProvider idpProvider;
// initialize our IdP provider
idpProvider = new DbIdpMetadataProvider(_providerData);
idpProvider.setParserPool(parser);
addIdpToMetadataManager(idpProvider);
}
/**
* Add the metadata provider to our cache
*/
private void addIdpToMetadataManager(DbIdpMetadataProvider _provider) throws MetadataProviderException {
ExtendedMetadataDelegate delegate;
ExtendedMetadata extMeta = new ExtendedMetadata();
// initialize our provider
_provider.initialize();
extMeta = createExtendedMetadata(_provider);
delegate = new ExtendedMetadataDelegate(_provider, extMeta);
delegate.setMetadataTrustCheck(false);
delegate.initialize();
metadataManager.addMetadataProvider(delegate);
metadataManager.setRefreshRequired(true);
metadataManager.refreshMetadata();
}
问题在于,刷新数据库条目时,不会应用IdP元数据中元素中定义的新签名证书。
打印元数据XML时,我可以看到新证书:
<!-- new signing key -->
<IDPSSODescriptor protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol">

如果重新启动服务,签名将被识别,响应将被成功处理。
有人知道我做错了什么吗?元数据管理器的刷新是否足以允许使用新证书?还是我错过了一步?
我在另一个帖子里找到了答案
由于我当前使用的是 XML 配置文件,因此我修改了安全上下文 XML 以设置凭据解析程序,如下所示:
<!-- Provider of default SAML Context -->
<bean id="contextProvider" class="org.springframework.security.saml.context.SAMLContextProviderImpl">
<property name="metadataResolver">
<bean class="com.mydomain.CustomMetadataCredentialResolver">
<constructor-arg index="0" ref="metadata" />
<constructor-arg index="1" ref="keyManager" />
<property name="useXmlMetadata" value="true" />
</bean>
</property>
</bean>
然后我创建了一个扩展org.springframework.security.saml.trust.MetadataCredentialResolver
的类
现在,我只需覆盖cacheCredentials方法:
@Component
public class CustomMetadataCredentialResolver extends MetadataCredentialResolver {
public CustomMetadataCredentialResolver(MetadataManager metadataProvider, KeyManager keyManager) {
super(metadataProvider, keyManager);
}
@Override
protected void cacheCredentials( MetadataCacheKey cacheKey, Collection<Credential> credentials ) {
//no-op
}
}
我可能会清理它以清除命令上的缓存,而不是从不缓存凭据,但现在它可以工作。
