Authenticaion Spring SOAP to Workday

Question

Soy muy nuevo en el manejo de solicitudes SOAP y estoy tratando de consumir la API SOAP de Workday enumerada aquí . He usado un gradle/ant para generar las clases del WSDL basado en el tutorial de Spring aquí

Ahora que las clases se han generado, puedo acceder a las funciones que necesito. El problema es que no sé cómo autenticar mis solicitudes.

Esto es lo que tengo hasta ahora:

import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import workday_Staffing.wsdl.GetWorkersRequestType;
import workday_Staffing.wsdl.GetWorkersResponseType;
public class StaffingClient extends WebServiceGatewaySupport {
public StaffingClient() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPath("workday_Staffing.wsdl");
setMarshaller(jaxb2Marshaller);
setUnmarshaller(jaxb2Marshaller);
}
public void makeWorkdayRequest() {
// make the request - missing some authentication here
GetWorkersRequestType request = new GetWorkersRequestType();
GetWorkersResponseType workersResponseType = (GetWorkersResponseType) getWebServiceTemplate()
.marshalSendAndReceive(request);
}
}

La respuesta aquí parece una buena pista pero me falta cómo construir el cliente y agregar la autenticación.

Cualquier ayuda será apreciada.

Answer 1

Principalmente, parece que te faltan las piezas de autenticación a través de un SOAPHandler para las Credenciales de WS-Security. FYI, esto no es Spring, pero estaba funcionando el código a partir de v16 de la API.

Gracias por el viaje por el carril de la memoria.

Pasos

1. Establecer el nombre de usuario y el inquilino de Workday
2. Establecer la contraseña de Workday
3. Establecer el código del cliente del servicio web (ex HumanResourcesService)
4. Establecer el puerto del cliente del servicio web
5. Agregue el controlador WorkdayCredentials al código auxiliar del cliente, con una referencia al puerto, usuario del día laborable @ inquilino y contraseña del día laborable.
6. Obtener el contexto de solicitud
7. Establezca el punto final del servicio web del día de trabajo del contexto Solicitud (consulte wdEndPoint)
8. GetWorkersRequestType
9. Opcionalmente establezca algunos parámetros para su solicitud
10. Obtenga la respuesta
11. Obtenga los datos de respuesta
