我使用此模板将 Spring Security SAML 与 Spring Boot 一起使用。然而，在我的 IDP 证书更新后，应用程序停止工作，我意识到我正在使用元数据互操作性配置文件 (MetaIOP) 进行签名验证。我相信由于我的 SP 仍在使用旧的 IDP 元数据 XML，因此签名验证失败并且我收到以下错误：

我尝试通过将签名证书导入密钥库并在配置中添加以下行来解决此问题：
// Metadata Resolver
@Bean
public MetadataCredentialResolver metadataCredentialResolver() throws MetadataProviderException, URISyntaxException {
MetadataCredentialResolver metadataCredentialResolver = new MetadataCredentialResolver(
metadata(), this.keyManager
);
metadataCredentialResolver.setUseXmlMetadata(false);
return metadataCredentialResolver;
}
和
// Setup advanced info about metadata
@Bean
public ExtendedMetadata extendedMetadata() {
...
extendedMetadata.setSecurityProfile("pkix");
extendedMetadata.setTrustedKeys(null);
return extendedMetadata;
}
但它似乎仍然无法使用相同的回溯。第 1 行的日志消息显示“SAML 协议消息未签名”这一事实让我更加困惑。那它为什么要评估信任呢？
