Force dynamic wsdl address location to https scheme

Nowadays all web applications must be secure with https protocol. A typical scenario involve a load balancer wich redirect all incoming https connections, to application servers responding on http port

We have had a problem with wsdl dynamic address location, exposed by an old web application based on Spring MVC 3.0 behind a Load Balancer. A dynamic wsdl is created at runtime by spring-ws with the tag dynamic-wsdl in the spring-ws context:

<sws:dynamic-wsdl id="myService"  portTypeName="myServiceSoap"  
   locationUri="/ws/MyServiceService" targetNamespace="http://www.myapp.it/myapp/schema/myappws">
              <sws:xsd location="/WEB-INF/wsdl/MyService.xsd"/>
</sws:dynamic-wsdl>

the portion of the service wsdl generated was like this:

<wsdl:service name="MySoapService">
    <wsdl:port binding="tns:MySoapSoap11" name="MySoapSoap11">        
         <soap:address location="http://www.myapp.com/myapp/ws/MyService"/>
    </wsdl:port>
</wsdl:service>

The scheme of the address location was http instead that https. To solve this, we have to force the schema to https. We have to create a new bean in the application context:

<bean id="myServiceWsdlDefinitionHandlerAdapter" name="wsdlDefinitionHandlerAdapter" class="it.github.parmag.MyServiceWsdlDefinitionHandlerAdapter">

The name must be “wsdlDefinitionHandlerAdapter”. Then the bean could be like this:

public class MyServiceWsdlDefinitionHandlerAdapter extends WsdlDefinitionHandlerAdapter {
	public CardplusWsdlDefinitionHandlerAdapter() {
	}

	@Override
	protected String transformLocation(String location, HttpServletRequest request) {
		String newLocation = super.transformLocation(location, request);
		newLocation = "https" + newLocation.substring(newLocation.indexOf(":"));
		return newLocation;
	}
}

Now, the address location is https:

<wsdl:service name="MySoapService">
    <wsdl:port binding="tns:MySoapSoap11" name="MySoapSoap11">        
         <soap:address location="https://www.myapp.com/myapp/ws/MyService"/>
    </wsdl:port>
</wsdl:service>
