How to send a SOAP request using WebServiceTemplate?

Question

I am trying to send a request to a SOAP webservice. I read this tutorial and prepared the following code. However, I am going to send different requests to multiple SOAP web

To send different SOAP requests to different SOAP services, you just need to make your WebServiceTemplate aware of all requests and responses it will have to process.

Create a Java class for each request and response like so:

package models;
import javax.xml.bind.annotation.XmlRootElement;
import java.io.Serializable;

@XmlRootElement
public class FlyRequest implements Serializable {

    private boolean nearByDeparture;

    public FlyRequest() {}

    public boolean isNearByDeparture() {
        return nearByDeparture;
    }

    public void setNearByDeparture(boolean nearByDeparture) {
        this.nearByDeparture = nearByDeparture;
    }
}

(The @XmlRootElement is because we use JAXB marshaller below; see Jaxb reference for more info).

The setup of the template is done for example like so:

    SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory(MessageFactory.newInstance());
    messageFactory.afterPropertiesSet();

    WebServiceTemplate webServiceTemplate = new WebServiceTemplate(messageFactory);
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setContextPath("models");
    marshaller.afterPropertiesSet();

    webServiceTemplate.setMarshaller(marshaller);
    webServiceTemplate.afterPropertiesSet();

"models" is the name of the package where the Request/Responses classes are, so that jaxb can find them.

Then you just instantiate the request of the class you want to perform the call, like so:

    // call fly service:
    FlyRequest flyRequest = new FlyRequest();
    flyRequest.setNearByDeparture(false);
    Object flyResponse = webServiceTemplate.marshalSendAndReceive("https://example.net/fly", flyRequest);

    // call purchase service:
    PurchaseRequest purchaseRequest = new PurchaseRequest();
    purchaseRequest.setPrice(100);
    Object purchaseResponse = webServiceTemplate.marshalSendAndReceive("https://example.net/purchase", purchaseRequest);

Similarly, you can cast the response objects into your JAXB classes defined above.
