Spring Integration should route Message (with SOAP Headers) - soap

Question

I am trying to write configure a gateway, which should take a complete SOAP Message and then delegate it to another SOAP Provider (incl. all SOAP headers of the first request).
What I have done so far:
1) web.xml
MessageDispatcherServlet with Mapping:
<servlet-mapping>
<servlet-name>spring-ws</servlet-name>
<url-pattern>/appservices/*</url-pattern>
</servlet-mapping>
2) Configuration with an Endpoint-Mapping
<bean class="org.springframework.ws.server.endpoint.mapping.UriEndpointMapping">
<property name="defaultEndpoint" ref="ws-in-gw"/>
</bean>
3) Configuration of Spring Integration inbound-gateway and outbound-gateway
<int-ws:inbound-gateway id="ws-in-gw"
request-channel="in"
reply-channel="out"
mapped-request-headers="*" />
<int:channel id="in" />
<int:channel id="out" />
<int-ws:outbound-gateway
id="ws-out-gw-status"
request-channel="in-status"
reply-channel="out-status"
uri="http://${delegationServer}/${delegation.contextroot}/soap/AnotherService"
interceptor="soapEnricher"
</int-ws:outbound-gateway>
<bean id="soapEnricher" class="foo.bar.SoapHeaderEnricher" />
public class SoapHeaderEnricher implements ClientInterceptor {
#Override
public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {
try {
SoapMessage soapMessage = (SoapMessage) messageContext.getRequest();
SoapHeader sh = soapMessage.getSoapHeader();
// can use sh.addHeaderElement(new QName(...)) now, but where are the original Headers???
} catch () {
}
}
My first Problem was, that the original SOAP Headers had been cut of, so I introduced the ' mapped-request-headers="*" ' attribute at the inbound gateway.
When I now configure a wire-tap, I see the Headers (myToken:MySecretToken) are received:
DEBUG 10:46:53 - [Payload DOMSource content=javax.xml.transform.dom.DOMSource#24a6ce98][Headers={errorChannel=org.springframework.messaging.core.GenericMessagingTemplate$TemporaryReplyChannel#43456ff4, myToken:MySecretToken=org.springframework.ws.soap.saaj.SaajSoapHeaderElement#3b91ead, ...}]
This is the SOAP Message for my test:
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:stat="http://status.service.promakler.provinzial.com/">
<soapenv:Header>
<myToken:MySecretToken xmlns=""
xmlns:myToken="http://foo.bar">12345</myToken:MySecretToken>
</soapenv:Header>
<soapenv:Body>
<stat:getStatus/>
</soapenv:Body>
</soapenv:Envelope>
So the Headers are now in my Message, but in the ClientInterceptor, there is no way to get the Headers (just the payload)?! I can add new Headers, but how can I get the original Header?
Can anybody give me a hint (or perhaps there is even a quiet simpler solution??)

Answer 1

Try to introduce a custom extension of DefaultSoapHeaderMapper and override populateUserDefinedHeader to extract those SaajSoapHeaderElement from the MessageHeaders and populate them to the SoapHeader. And finally inject your solution to the header-mapper of your <int-ws:outbound-gateway>.
