XADES4j-XML签名验证错误-未指定签名节点

Question

我来用XAdES4j对XML文件进行签名，但在验证时，我总是得到"未指定签名节点"。显然signatureParent就是null！如何解决？

这是我的代码：

FileSystemDirectoryCertStore certStore = new FileSystemDirectoryCertStore(".");
KeyStore trustAnchors = createAndLoadJKSKeyStore(".\myStore", "mystorepass");
CertificateValidationProvider certValidator = new PKIXCertificateValidationProvider(trustAnchors, false, certStore.getStore());
XadesVerificationProfile p = new XadesVerificationProfile(certValidator);
XadesVerifier v = p.newVerifier();
Document sourceDoc = Signapp.getDocument(".\TEST.XML.FILE.xml");
Element signatureParent = (Element)sourceDoc.getElementsByTagNameNS(Constants.SignatureSpecNS, Constants._TAG_SIGNATURE).item(0);;
XAdESVerificationResult r = v.verify(signatureParent,null);

Answer 1

这里是我的getDocument方法：

        File fXmlFile = new File(path);
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(fXmlFile);
        doc.getDocumentElement().normalize();
        return doc;

Answer 2

您需要：

dbFactory.SetNamespaceAware(true);
