Spring SAML 2.0 - 导入 IDP 的本地元数据 - MetadataProviderException
Spring SAML 2.0 - Importing an IDP's local Metadata - MetadataProviderException
我已经在我的系统中实施了 SAML 2.0（我正在扮演 SP 角色）。
当我与带有远程元数据的 IDP 集成时，一切正常，这是由 URL.
提供给我的
我正在尝试与已向我发送其元数据的 IDP 集成，但由于某种原因它不起作用。
我试过：
@豆
@Qualifier("idp-ssocircle")
publicExtendedMetadataDelegate ssoCircleExtendedMetadataProvider()
抛出 MetadataProviderException {
ClasspathResource 元数据 = null；
尝试 {
metadata = new ClasspathResource("/saml/metadata/sso.xml");
logger.info("Metadata Exists!!");
} 赶上（异常 e）{
logger.debug("Can't fetch metadata!!!");
}
计时器 timer = new Timer(true);
ResourceBackedMetadataProvider provider = new ResourceBackedMetadataProvider(timer,metadata);
return new ExtendedMetadataDelegate(provider, extendedMetadata());
}
我也试过了：
@豆
@Qualifier("idp-ssocircle")
publicExtendedMetadataDelegate ssoExtendedMetadataProvider()
抛出 MetadataProviderException {
文件元数据=空；
尝试 {
元数据=新文件（"C:\my-path\saml\metadata\sso.xml"）；
logger.info("Metadata Exists!!");
} 赶上（异常 e）{
logger.debug("Can't fetch metadata!!!");
}
FilesystemMetadataProvider 提供者 = null；
provider = new FilesystemMetadataProvider（元数据）；
return new ExtendedMetadataDelegate(provider, extendedMetadata());
}
在这两种情况下，它都打印出元数据存在，我得到的错误是：
