我有一个需要与之交谈的SOAP服务。第一个SOAP请求在SOAP标头中接收带有 sessionID 元素的响应,我需要在最终发布命令中发送该元素。
要获取此sessionID值,我计划使用 ClientInterceptor 。在我的 WebServiceGatewaySupport 的实现中,我注册了我的拦截器:
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;
}
}
但是我不断回到空的SOAP标头。我正在运行Wireshark,并且可以在返回的SOAP数据包中清楚地看到 sessionID 令牌,这样就不知道发生了什么。有什么想法吗?
答案 0 :(得分:4)
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中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;
}
}
我使用拦截器的地方:
public class MySoapClient extends WebServiceGatewaySupport {
public MySoapClient() {
this.setInterceptors(new ClientInterceptor[] { new MyWebServiceClientInterceptor() });
...
}
...
}
回调以设置自定义SOAP标头: class MySoapActionCallback实现了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);
}
}
}
我使用回调的地方:
JAXBElement<ReturnType> result = (JAXBElement<ReturnType>) getWebServiceTemplate().marshalSendAndReceive(of.createRelease(null), new MySoapActionCallback());
