Support both SOAP 1.1 and SOAP 1.2 messages in Spring-WS

Question

Looked all over for a response to my problem with little success.

I have a Spring boot app which needs to expose both SOAP 1.1 and SOAP 1.2 endpoints. I understand the SOAP version can be configured on the WebServiceMessageFactory bean (currently using SAAJ), but this sets a fixed SOAP version for all endpoints.

Is there a way to achieve this?

Thank you

Doesn't seem to be a built in way of doing this.

I ended up subclassing SaajSoapMessageFactory and declaring that as a Bean, like this:

@Bean("messageFactory")
public SoapMessageFactory messageFactory() {
   var messageFactory = new DualProtocolSaajSoapMessageFactory();

   return messageFactory;
}

This new class is a copy of SaajSoapMessageFactory with a few changes: - It internally has two message factories, one for 1.1 and one for 1.2

public DualProtocolSaajSoapMessageFactory() {
    super();

    try {
        messageFactory11 = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);
        messageFactory12 = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
    } catch (Exception ex) {
        throw new SoapMessageCreationException("Could not create SAAJ MessageFactory: " + ex.getMessage(), ex);
    }
}

And then, basically, just override createWebServiceMessage:

@Override
public SaajSoapMessage createWebServiceMessage(InputStream inputStream) throws IOException {
    MimeHeaders mimeHeaders = parseMimeHeaders(inputStream);
    try {
        inputStream = checkForUtf8ByteOrderMark(inputStream);
        SOAPMessage saajMessage = null;

        if (mimeHeaders.getHeader(HttpHeaders.CONTENT_TYPE)[0].contains(MimeTypeUtils.TEXT_XML_VALUE)) {
            saajMessage = messageFactory11.createMessage(mimeHeaders, inputStream);
        } else {
            saajMessage = messageFactory12.createMessage(mimeHeaders, inputStream);
        }
...snip

A little hacky, but does what it needs to do.
