Spring ClientInterceptor在響應中顯示空SOAP標頭

Question

我有一個SOAP服務，我需要與之交談。 第一個SOAP請求接收帶有SOAP標頭中的sessionID元素的響應，我需要在最終發布命令中發送該響應。

要獲取此sessionID值，我計划使用ClientInterceptor 。 在我的WebServiceGatewaySupport實現中，我注冊了我的攔截器：

this.setInterceptors(new ClientInterceptor[] { new MyWebServiceClientInterceptor() });

我的攔截器：

public class MyWebServiceClientInterceptor implements ClientInterceptor {

    public final QName SessionID_QNAME = new QName("http://xml.example.com/ws/session", "sessionID");

    public boolean handleFault(MessageContext context) throws WebServiceClientException {
        logger.info("Handle Fault");
        return true;
    }       

    public boolean handleResponse(MessageContext context) throws WebServiceClientException {
        logger.info("Handle Response");
        SoapMessage soapMessage = (SoapMessage) context.getRequest();
        SoapHeader soapHeader = soapMessage.getSoapHeader();

        logger.info("Response Header: " + soapHeader.getName());
        Iterator<SoapHeaderElement> qn = soapHeader.examineAllHeaderElements();
        while (qn.hasNext()) {
            SoapElement elem = qn.next();
            logger.info(elem.toString());
        }
        Iterator<QName> an = soapHeader.getAllAttributes();
        while (an.hasNext()) {
            QName elem = an.next();
            logger.info(elem.toString());
        }
        return true;
    }

    public boolean handleRequest(MessageContext context) throws WebServiceClientException {
        logger.info("Handle Request");
        return true;
    }
}

但是我一直在回到一個空的SOAP標頭。 我正在運行Wireshark並且可以清楚地看到返回的SOAP數據包中的sessionID令牌，因此丟失了所發生的事情。 有任何想法嗎？

我是個白痴。 '這是一個錯字。 我需要打電話：

SoapMessage soapMessage = (SoapMessage) context.getResponse();

不：

SoapMessage soapMessage = (SoapMessage) context.getRequest();

想要在請求上設置標頭並在響應上接收標頭的人的完整代碼：

ClientInterceptor接收自定義SOAP標頭值：

public class MyWebServiceClientInterceptor implements ClientInterceptor {

    public boolean handleFault(MessageContext context) throws WebServiceClientException {
        return true;
    }

    public boolean handleResponse(MessageContext context) throws WebServiceClientException {
        SoapMessage soapMessage = (SoapMessage) context.getResponse();
        SoapHeader soapHeader = soapMessage.getSoapHeader();

        Iterator<SoapHeaderElement> qn = soapHeader.examineHeaderElements(MY_SESSIONID_QNAME);

        while (qn.hasNext()) {
            SoapElement elem = qn.next();
            SoapHeaderElement headerElem = (SoapHeaderElement) elem;
            if (StringUtil.validString(headerElem.getText())) {
                if (!headerElem.getText().equals(sessionId)) {
                    sessionId = headerElem.getText();
                    logger.info("Bound to Session ID: " + sessionId);
                }
            }
        }
        return true;
    }

    public boolean handleRequest(MessageContext context) throws WebServiceClientException {
        return true;
    }
}

我在哪里使用攔截器：

public class MySoapClient extends WebServiceGatewaySupport {

public MySoapClient() {
    this.setInterceptors(new ClientInterceptor[] { new MyWebServiceClientInterceptor() });
    ...
}

...
}

回調以設置自定義SOAP標頭：類MySoapActionCallback實現WebServiceMessageCallback {

    public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
        SaajSoapMessage soapMessage = (SaajSoapMessage) message;
        SoapHeaderElement messageId = soapMessage.getSoapHeader().addHeaderElement(SessionID_QNAME);
        if (StringUtil.validString(sessionId)) {
            messageId.setText(sessionId);
        }
    }
}

我在哪里使用回調：

JAXBElement<ReturnType> result = (JAXBElement<ReturnType>) getWebServiceTemplate().marshalSendAndReceive(of.createRelease(null), new MySoapActionCallback());
