Question

我收到带有Xades EPES签名的XML Invoice，我必须控制它。所以我尝试用Xades4j做到这一点。我已经解决了很多错误但我坚持错误：

errxades4j.verification.SignaturePolicyNotAvailableException: Verification failed for property 'SignaturePolicyIdentifier': signature policy document is not available
    at xades4j.verification.SignaturePolicyVerifier.verify(SignaturePolicyVerifier.java:67)
    at xades4j.verification.SignaturePolicyVerifier.verify(SignaturePolicyVerifier.java:38)
    at xades4j.verification.QualifyingPropertiesVerifierImpl.verifyProperties(QualifyingPropertiesVerifierImpl.java:58)
    at xades4j.verification.XadesVerifierImpl.verify(XadesVerifierImpl.java:202)

用于验证签名的Java代码：

FileInputStream fis = new FileInputStream("keystore.jks");
KeyStore trustAnchors = KeyStore.getInstance("jks");
trustAnchors.load(fis,"password".toCharArray());
fis.close();

CertificateValidationProvider certValidator = new PKIXCertificateValidationProvider(trustAnchors, false);
XadesVerificationProfile p = new XadesVerificationProfile(certValidator);
XadesVerifier v = p.newVerifier();

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db =  dbf.newDocumentBuilder();
FileInputStream is = new FileInputStream(filename);
Document doc = db.parse(is);

Element sigElem = (Element)doc.getElementsByTagNameNS(Constants.SignatureSpecNS, Constants._TAG_SIGNATURE).item(0);
XAdESVerificationResult r = null;
r = v.verify(sigElem,null);

如果有必要，我可以发布一种XML文件的摘录，我尝试在匿名化后验证。

感谢。我已经查看并尝试了所有我发现的（在网上，xades4j示例，xades4j junit类......）但似乎没有解决我的错误。

您需要指定自己的政策文件提供商，如下所示：p.withPolicyDocumentProvider()。您必须实现自己的策略提供程序，该提供程序实现接口SignaturePolicyInfoProvider和SignaturePolicyDocumentProvider。（至少我这样做了）

编辑您的评论：

您需要实现SignaturePolicyInfoProvider.getSignaturePolicyDocumentStream()，它会返回InputStream。这可以是FileInputStream

示例：

public class FilebasedSignaturePolicyProvider implements SignaturePolicyDocumentProvider { @Override public InputStream getSignaturePolicyDocumentStream(ObjectIdentifier sigPolicyId) { String oid = sigPolicyId.getIdentifier(); try { return new FileInputStream("directory-to-my-policy-files/" + oid); } catch (FileNotFoundException e) { // handle error } } }
