【中文标题】SOAP XML WS-Security 签名验证【英文标题】：SOAP XML WS-Security signature verification 【发布时间】：2020-12-16 08:00:51 【问题描述】：我能够使用 WS-Security 签名的证书对 SOAP XML 进行签名。但我无法验证它的签名。在验证签名时会导致异常，我们将不胜感激帮助解决问题
SOAP Enveloped WS-Security signature:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header>
<ws:Security xmlns:ws="http://schemas.xmlsoap.org/..." s:actor="test">
<dsig:Signature xmlns:dsig="http://www.w3.org/2000/09/..." id="Sample">
...
</dsig:Signature>
</ws:Security>
</s:Header>
<s:Body>
...
</s:Body>
</s:Envelope>
当我尝试验证 SOAP XML 时，我收到以下异常：
org.apache.xml.security.signature.MissingResourceFailureException：URI #Body 的引用没有 XMLSignatureInput
public static boolean isSOAPXmlWSSEDigitalSignatureValid(String signedXmlFilePath, PublicKey publicKey) throws Exception
String xmlContent = getFileString(signedXmlFilePath);
Document signedDoc = getDocument(xmlContent.trim(), true);
signedDoc.createElementNS(DSIG_NS, "ds"); // qualifiedName = "ds";
signedDoc.createElementNS(WSU_NS, "wsu");
signedDoc.createElementNS(WSSE_NS, "wsse");
// load signature
NodeList signatureNodes = signedDoc.getElementsByTagNameNS(javax.xml.crypto.dsig.XMLSignature.XMLNS, "Signature");
if (signatureNodes.getLength() == 0)
throw new Exception("No XML Digital Signature Found, document is discarded");
Element sigElement = (Element) signatureNodes.item(0);
if (sigElement == null)
throw new Exception("Signature element is null!");
org.apache.xml.security.Init.init();
org.apache.xml.security.signature.XMLSignature signature = new XMLSignature(sigElement, "");
return signature.checkSignatureValue(publicKey);
通过使用以下函数，我可以签署 XML
