我想使用jaxb使用soap服务。

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Header/>
    <SOAP-ENV:Body>
      <ns2:Add xmlns:ns2="http://tempuri.org/">
         <ns2:intA>10</ns2:intA><ns2:intB>20</ns2:intB>
      </ns2:Add>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

但回应是一个肥皂例外，正如标题所说。

Caused by: org.springframework.ws.soap.client.SoapFaultClientException: System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction: .
   at System.Web.Services.Protocols.Soap11ServerProtocolHelper.RouteRequest()
   at System.Web.Services.Protocols.SoapServerProtocol.RouteRequest(SoapServerMessage message)
   at System.Web.Services.Protocols.SoapServerProtocol.Initialize()
   at System.Web.Services.Protocols.ServerProtocol.SetContext(Type type, HttpContext context, HttpRequest request, HttpResponse response)

下面是我的soap配置代码。源代码示例：https://howtodoinjava.com/spring-boot/spring-soap-client-webservicetemplate/

public class ConsumeSoapApplication {
            public static String wsdlurl = "http://www.dneonline.com/calculator.asmx?wsdl";
            public static void main(String[] args) {
                try {
                    JAXBContext.newInstance(com.dxc.service.soap.service.calc.ObjectFactory.class.getPackage().getName(),
                            com.dxc.service.soap.service.calc.ObjectFactory.class.getClassLoader());
                } catch (JAXBException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                SpringApplication.run(ConsumeSoapApplication.class, args);
            }

            @Bean
            CommandLineRunner lookup(SoapConnector soapConnector) {
                return args -> {
                    Integer a = 10;
                    Integer b = 20;
                    if(args.length>0){
                        a = Integer.parseInt(args[0]);
                        b = Integer.parseInt(args[1]);
                    }

                    Add add = new Add();
                    add.setIntA(a);
                    add.setIntB(b);
                    AddResponse addRes = (AddResponse) soapConnector.callWebService(wsdlurl, add);
                    System.out.println("Got Response As below ========= : ");
                    System.out.println("Added result : "+addRes.getAddResult());
                };
            }
        }

@Configuration
public class SoapConfig {    
    @Bean
        public Jaxb2Marshaller marshaller() {
            try {
                JAXBContext jb = JAXBContext.newInstance(com.dxc.service.soap.service.calc.ObjectFactory.class.getPackage().getName(),
                        com.dxc.service.soap.service.calc.ObjectFactory.class.getClassLoader());
                //Jaxb2Marshaller marshaller = (Jaxb2Marshaller) jb.createMarshaller();
                Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
                marshaller.setPackagesToScan("com.dxc.service.soap.service.calc");
                //marshaller.setContextPath("com.dxc.service.soap.calc");
                return marshaller;
            } catch (JAXBException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }   
            return null;
        }

        @Bean
        public SoapConnector soapConnector(Jaxb2Marshaller marshaller) {
            SoapConnector client = new SoapConnector();
            client.setDefaultUri("http://www.dneonline.com/calculator.asmx");
            client.setMarshaller(marshaller);
            client.setUnmarshaller(marshaller);
            return client;
        }

请帮帮我。谢谢。
