spring-ws Generating SOAP Service without Request Parameter Suffix

Question

I need to use some XSDs files from an industry standard to generate a SOAP webservice from it. REST is not possible because the consumer is only able to do SOAP calls.

The parameters in the XSD are defined as the following:

   <xsd:element name="getData">
      <xsd:complexType>
         <xsd:sequence>
            <xsd:element name="Request" type="CT_getDataRequest" minOccurs="1" maxOccurs="1"/>
         </xsd:sequence>
      </xsd:complexType>
   </xsd:element>
   <xsd:element name="getDataResponse">
      <xsd:complexType>
         <xsd:sequence>
            <xsd:element name="Response" type="CT_getDataResponse" minOccurs="1" maxOccurs="1"/>
         </xsd:sequence>
      </xsd:complexType>
   </xsd:element>

That is my endpoint definition:

@Endpoint
@RequiredArgsConstructor
public class DataEndpoint {
    private static final String NAMESPACE_URI = "http://www.machine-config.net/namespace/data";

    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "getData")
    @ResponsePayload
    public GetDataResponse getData(@RequestPayload GetData request) {
    }
}

Here is my WsConfiguration:

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {

    @Bean
    public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
        MessageDispatcherServlet messageDispatcherServlet = new MessageDispatcherServlet();
        messageDispatcherServlet.setApplicationContext(applicationContext);
        messageDispatcherServlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean(messageDispatcherServlet, "/ws/*");
    }

    @Bean(name = "dataDefinition")
    public DefaultWsdl11Definition dataWsdl11Definition() {
        DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
        wsdl11Definition.setPortTypeName("dataServicePortType");
        wsdl11Definition.setLocationUri("/ws");
        wsdl11Definition.setTargetNamespace("http://www.machine-config.net/namespace");
        wsdl11Definition.setSchemaCollection(dataSchemas());
        
        return wsdl11Definition;
    }

    @Bean(name = "dataSchema")
    public XsdSchemaCollection dataSchemas() {
        CommonsXsdSchemaCollection xsds = new CommonsXsdSchemaCollection(new ClassPathResource("xsd/data-2.18.1433.2.xsd"));
        xsds.setUriResolver(new DefaultURIResolver());
        xsds.setInline(true);
        return xsds;
    }
}

But inside the generated WSDL the following operation is generated:

<wsdl:operation name="getData">
    <wsdl:output message="sch0:getDataResponse" name="getDataResponse"> </wsdl:output>
</wsdl:operation>

The wsdl:input part is missing.

When I change the xsd:element getData to getDataRequest the wsdl:input element is generated. But that workaround will not work because the XSD will be delivered by a vendor and I am not allowed to change anything in this file.

How can I make spring-ws to recognize the input parameter without the Request Suffix?
