相关调用代码是这样的：

public class CountryClient extends WebServiceGatewaySupport {

    private static final Logger log = ();

    public GetCountryResponse getCountry(String country) {

        GetCountryRequest request = new GetCountryRequest();
        (country);

        ("Requesting location for " + country);

        GetCountryResponse response = (GetCountryResponse) getWebServiceTemplate()
                .marshalSendAndReceive("http://localhost:8080/ws/countries", request,
                        new SoapActionCallback(
                                "/guides/gs-producing-web-service/GetCountryRequest"));

        return response;
    }

}

改成这样即可：

public class CountryClient extends WebServiceGatewaySupport {

    private static final Logger log = ();

    public GetCountryResponse getCountry(String country) {

        GetCountryRequest request = new GetCountryRequest();
        (country);

        ("Requesting location for " + country);

        JAXBElement<GetFileRequestResponse> response = (JAXBElement<GetFileRequestResponse>) getWebServiceTemplate()
                .marshalSendAndReceive("http://localhost:8080/ws/countries", request,
                        new SoapActionCallback(
                                "/guides/gs-producing-web-service/GetCountryRequest"));

        return ();
    }

}
