我有一个需要与之交谈的SOAP服务.第一个SOAP请求在SOAP标头中收到带有sessionID元素的响应,我需要在最终发布命令中发送该响应.
要获取此sessionID值,我计划使用ClientInterceptor.在实现WebServiceGatewaySupport的过程中,我注册了拦截器:
this.setInterceptors(new ClientInterceptor[] { new MyWebServiceClientInterceptor() });
我的拦截器:
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,我一直找回一个空的SOAP标头.我正在运行Wireshark,可以清楚地看到返回的SOAP数据包中的sessionID令牌,因此对正在发生的事情一无所知.有任何想法吗?
解决方法:
我是个白痴. ‘是错字.我需要打电话给:
SoapMessage soapMessage = (SoapMessage) context.getResponse();
不:
SoapMessage soapMessage = (SoapMessage) context.getRequest();
那些想要在请求上设置标头并在响应上接收标头的人的完整代码:
ClientInterceptor接收自定义SOAP标头值:
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;
}
}
我在哪里使用拦截器:
public class MySoapClient extends WebServiceGatewaySupport {
public MySoapClient() {
this.setInterceptors(new ClientInterceptor[] { new MyWebServiceClientInterceptor() });
...
}
...
}
设置自定义SOAP标头的回调:
类MySoapActionCallback实现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);
}
}
}
我在哪里使用回调:
JAXBElement<ReturnType> result = (JAXBElement<ReturnType>) getWebServiceTemplate().marshalSendAndReceive(of.createRelease(null), new MySoapActionCallback());
