Customizing Spring Integration Web Service SOAP Envelope/Header - soap

Question

I am trying to send a SOAP request using Spring Integration like
<int:chain input-channel="wsOutChannel" output-channel="stdoutChannel">
<int-ws:header-enricher>
<int-ws:soap-action value="..."/>
</int-ws:header-enricher>
<int-ws:outbound-gateway
uri="..."/>
</int:chain>
but you can only add the SOAP body, and Spring Integration adds the envelope, header, and body tags like
<SOAP-ENV:Envelope>
<SOAP-ENV:Header>
<SOAP-ENV:Body>
...
</SOAP-ENV:Body>
<SOAP-ENV:Header>
</SOAP-ENV:Envelope>
I need to customize the envelope and header tags with specific attributes, for example:
<soapenv:Envelope attribute1="value1" attribute2="value2">
and child elements, for example:
<soapenv:Header>
<child>...<child>
<soapenv:Header>
Is this possible with Spring Integration Web Services, or should I not use int-ws:outbound-gateway and take a different approach?

Answer 1

You can add a ClientInterceptor (via the interceptor attribute) which allows you to modify the request before it's sent out.
EDIT
#Artem's suggestion is simpler but the interceptor gives you access to the response too; but either way, the code is similar.
For the interceptor:
public class MyInterceptor extends ClientInterceptorAdapter {
#Override
public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {
SoapMessage request = (SoapMessage) messageContext.getRequest();
SoapEnvelope envelope = request.getEnvelope();
envelope.addAttribute(new QName("foo"), "bar");
SoapHeader header = envelope.getHeader();
header.addHeaderElement(new QName("http://fiz/buz", "baz"));
return super.handleRequest(messageContext);
}
}
For the callback version:
#Override
public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
SoapEnvelope envelope = ((SoapMessage) message).getEnvelope();
envelope.addAttribute(new QName("foo"), "bar");
SoapHeader header = envelope.getHeader();
header.addHeaderElement(new QName("http://fiz/buz", "baz"));
}

I thing you can inject WebServiceMessageCallback:
<xsd:attribute name="request-callback" type="xsd:string">
<xsd:annotation>
<xsd:documentation>
Reference to a Spring Web Services WebServiceMessageCallback. This enables changing
the Web Service request message after the payload has been written to it but prior
to invocation of the actual Web Service.
</xsd:documentation>
<xsd:appinfo>
<tool:annotation kind="ref">
<tool:expected-type type="org.springframework.ws.client.core.WebServiceMessageCallback"/>
</tool:annotation>
</xsd:appinfo>
</xsd:annotation>
</xsd:attribute>
and cast the message to the SoapMessage and use its getEnvelope() to customize a desired way.
