                </plugin>
    
            </plugins>

相关调用代码是这样的：

public class CountryClient extends WebServiceGatewaySupport {
    
        private static final Logger log = LoggerFactory.getLogger(CountryClient.class);
    
        public GetCountryResponse getCountry(String country) {
    
            GetCountryRequest request = new GetCountryRequest();
            request.setName(country);
    
            log.info("Requesting location for " + country);
    
            GetCountryResponse response = (GetCountryResponse) getWebServiceTemplate()
                    .marshalSendAndReceive("http://localhost:8080/ws/countries", request,
                            new SoapActionCallback(
                                    "http://spring.io/guides/gs-producing-web-service/GetCountryRequest"));
    
            return response;
        }
    
    }

改成这样即可：

public class CountryClient extends WebServiceGatewaySupport {
    
        private static final Logger log = LoggerFactory.getLogger(CountryClient.class);
    
        public GetCountryResponse getCountry(String country) {
    
            GetCountryRequest request = new GetCountryRequest();
            request.setName(country);
    
            log.info("Requesting location for " + country);
    
            JAXBElement<GetFileRequestResponse> response = (JAXBElement<GetFileRequestResponse>) getWebServiceTemplate()
                    .marshalSendAndReceive("http://localhost:8080/ws/countries", request,
                            new SoapActionCallback(
                                    "http://spring.io/guides/gs-producing-web-service/GetCountryRequest"));
    
            return response.getValue();
        }
    
    }
