我正在尝试使用 this 使用 Xades4J 签署一个简单的 XML例如，但我收到此错误:

我的代码是这样的

public static void main(String[] args) throws Exception {

.newInstance()
.newDocumentBuilder()
.parse(new File(DOCUMENT));
Element elem = doc.getDocumentElement();
DOMHelper.useIdAsXmlId(elem);
KeyingDataProvider kdp = new FileSystemKeyStoreKeyingDataProvider(
"pkcs12",
CERT_FOLDER + CERT,
new FirstCertificateSelector(),
new DirectPasswordProvider(PASS),
new DirectPasswordProvider(PASS),
true);
// here I tried also EManifest (the XML root tag) and name (since elem has a "name" attribute)
DataObjectDesc obj = new DataObjectReference("#" + elem.getAttribute("Id"))
.withTransform(new EnvelopedSignatureTransform());
SignedDataObjects dataObjs = new SignedDataObjects().withSignedDataObject(obj);
XadesSigner signer = new XadesBesSigningProfile(kdp).newSigner();
signer.sign(dataObjs, elem); // fails here
/*TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File(SIGNED));
transformer.transform(source, result);*/
}
}
XML 是海关流程的示例文档，可以在 here 找到。 .
任何建议将不胜感激。
最佳答案
不需要创建ID。你可以这样做:
DataObjectDesc dataObjRef = new DataObjectReference("").withTransform(new EnvelopedSignatureTransform());
总结将“”传递给 DataObjectReference
