I have created a Soap Endpoint based on Client's request and that endpoint currently works with Content-Type:text/xml. But Client wants to send Content-Type as application/xml. I cannot ask client to change their content-type and I have to fix my server endpoint to work according to client using Spring boot. Please help and let me know, how can I fix the endpoint so that it can accept application/xml. Thanks in advance. Below is my Stacktrace:

Endpoint code:
@Endpoint
public class RequestEndpoint {
@PayloadRoot(namespace = "http://www.networks.com/RoR", localPart = "Submit")
@ResponsePayload
public SResponse handleRequest(@RequestPayload Submitrequest) throws URISyntaxException, IOException {
SResponse sResponse = new SResponse();
sResponse.setCommandStatus("0");
return sResponse;
}
Since I don't have control over the header that client sends, I have created a workaround. I have created a bean for SaajSoapMessageFactory and passed a CustomSOAPMessageFactoryImpl which actually validates the "content-type" header. In CustomSOAPMessageFactoryImpl, I am overriding a method that validates the header. Here, there is an if condition which add/updates the content-type header's value as text/xml if the value is empty or "application/xml" respectively. This solution is working fine for me.
@Bean
public SaajSoapMessageFactory messageFactory() {
SaajSoapMessageFactory saajSoapMessageFactory = new SaajSoapMessageFactory();
saajSoapMessageFactory.setMessageFactory(new CustomSOAPMessageFactoryImpl());
return saajSoapMessageFactory;
}
Below is the CustomSOAPMessageFactoryImpl:

import java.io.InputStream;
import javax.xml.soap.MimeHeaders;

public class CustomSOAPMessageFactoryImpl extends SOAPMessageFactory1_1Impl{
private static final Logger logger = LogManager.getLogger(CustomSOAPMessageFactoryImpl.class);
@Override
public SOAPMessage createMessage(MimeHeaders headers, InputStream in) throws IOException, SOAPExceptionImpl {
if (headers == null) {
headers = new MimeHeaders();
}
//The OR condition is a work around for Client, if they are not sending text/xml
if (getContentType(headers) == null || ContentType.APPLICATION_XML.getMimeType().equals(getContentType(headers))) {
logger.info("Received Content-Type Header Value as {}, setting it as {}", getContentType(headers), SOAPConstants.SOAP_1_1_CONTENT_TYPE);
headers.setHeader("Content-Type", SOAPConstants.SOAP_1_1_CONTENT_TYPE);
}
MessageImpl msg = new Message1_1Impl(headers, in);
msg.setLazyAttachments(lazyAttachments);
return msg;
}
}
