Spring WS如何获取服务器端soap响应xml以添加带有符号的soap标头

Question

我有 spring 网络服务。我需要签署服务器（我的网络服务）为肥皂请求提供的肥皂响应。 xwss 和 wss4j 拦截器不适合这个，因为我需要这种格式：

<ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
<ds:SignedInfo>
<ds:CanonicalizationMethod Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"/>
<ds:SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#gost34310-gost34311"/>
<ds:Reference URI="#b0525e8a-dbcb-45da-abfd-d1bdecf6ccbb">
<ds:Transforms>
<ds:Transform Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315#WithComments"/>
<ds:Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/>
</ds:Transforms>
<ds:DigestMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#gost34311"/>
<ds:DigestValue>valval=</ds:DigestValue>
</ds:Reference>
</ds:SignedInfo>
<ds:SignatureValue>
valuevalue==
</ds:SignatureValue>
<ds:KeyInfo>
<ds:X509Data>
<ds:X509Certificate>
valuevaluevalue=
</ds:X509Certificate>
</ds:X509Data>
</ds:KeyInfo>
</ds:Signature>

我需要在我的回复中将此添加到肥皂标题块中。为此，我必须获取整个soap响应的xml，包括soap env等。

如何获取该xml，通过添加soap标头对其进行修改，最后将其作为响应发送？

请帮帮我

好的，我终于用自定义 SmartSoapEndpointInterceptor 解决了这个问题。我创建了实现 SmartSoapEndpointInterceptor 的 MyCustomEndpointInterceptor 并根据我的需要更改了 handleResponse。源代码为：

public class MyCustomEndpointInterceptor implements SmartSoapEndpointInterceptor {

    @Override
    public boolean handleRequest(MessageContext messageContext, Object endpoint) throws Exception {
        return true;
    }

    @Override
    public boolean handleResponse(MessageContext messageContext, Object endpoint) throws Exception {
        SaajSoapMessage soapResponse = (SaajSoapMessage) messageContext.getResponse();
        DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(strMsg);
        Document doc = soapResponse.getDocument();
        // Look for the SOAP header
        Element headerElement = null;
        NodeList nodes = doc.getElementsByTagNameNS("http://schemas.xmlsoap.org/soap/envelope/", "Header");
        if (nodes.getLength() == 0) {
            System.out.println("Adding a SOAP Header Element");
            headerElement = doc.createElementNS("http://schemas.xmlsoap.org/soap/envelope/", "Header");
            nodes = doc.getElementsByTagNameNS("http://schemas.xmlsoap.org/soap/envelope/", "Envelope");
            if (nodes != null) {
                Element envelopeElement = (Element) nodes.item(0);
                headerElement.setPrefix(envelopeElement.getPrefix());
                envelopeElement.appendChild(headerElement);
            }
        } else {
            System.out.println("Found " + nodes.getLength() + " SOAP Header elements.");
            headerElement = (Element) nodes.item(0);
        }

        Provider kncaProvider = new IolaProvider();
        Security.addProvider(kncaProvider);

        KeyStore ks = KeyStore.getInstance("pkcs12", kncaProvider.getName());

        ks.load(new FileInputStream(keypath), keypass.toCharArray());

        PrivateKey privateKey = (PrivateKey) ks.getKey(keyalias, keypass.toCharArray());

        XMLSignature sig = new XMLSignature(doc, "", "http://www.w3.org/2001/04/xmldsig-more#gost34310-gost34311");
        headerElement.appendChild(sig.getElement());
        Transforms transforms = new Transforms(doc); 
        transforms.addTransform("http://www.w3.org/2000/09/xmldsig#enveloped-signature");
        transforms.addTransform("http://www.w3.org/TR/2001/REC-xml-c14n-20010315#WithComments");
        sig.addDocument("", transforms,"http://www.w3.org/2001/04/xmldsig-more#gost34311"); 
        X509Certificate cert = (X509Certificate) ks.getCertificate(somealias);
        sig.addKeyInfo(cert); 
        sig.sign(privateKey);

        return true;
    }

    @Override
    public boolean handleFault(MessageContext messageContext, Object endpoint) throws Exception {
        return true;
    }

    @Override
    public boolean shouldIntercept(MessageContext messageContext, Object endpoint) {
        return true;
    }

    @Override
    public boolean understands(SoapHeaderElement header) {
        return true;
    }
}

使用 spring-ws，您可以将 MessageContext messageContext 参数添加到任何处理soap请求的方法：

@PayloadRoot(localPart = LOCAL_PART, namespace = NAMESPACE)
@ResponsePayload
public <return type> handleRequest(@RequestPayload final <request type> request,
                                         MessageContext messageContext)

使用消息上下文，您可以检索响应标头并根据需要对其进行编辑。
