如何使用WebServiceTemplate发送SOAP请求？

Question

我正在尝试向SOAP Web服务发送请求.我阅读了本教程并准备了以下代码.但是,我将向多个SOAP Web服务发送不同的请求,而本教程则关注一个请求.如何使用WebserviceTemplate？发送SOAP请求？

WebServiceTemplate

    SoapMessage soapMsg = new SoapMessage();
    soapMsg.setUsername("Requester");
    soapMsg.setPassword("Pass");
    soapMsg.setLanguageCode("EN");
    Request request = new Request();
    request.setDeparture("FDH");
    request.setDestination("HAM");
    Date date = new Date();
    SimpleDateFormat frm2 = new SimpleDateFormat("yyyy-MM-dd");
    request.setDepartureDate(frm2.parse(frm2.format(date)));
    request.setNumADT(1);
    request.setNumCHD(0);
    request.setNumInf(0);
    request.setCurrencyCode("EUR");
    request.setWaitForResult(true);
    request.setNearByDepartures(true);
    request.setNearByDestinations(true);
    request.setRronly(false);
    request.setMetaSearch(false);
    soapMsg.setRequest(request);
    WebServiceTemplate webServiceTemplate = new WebServiceTemplate().  //how to create object and send request!
    Object response = webServiceTemplate.marshalSendAndReceive(
            "https://aaa5.elsyarres.net", soapMsg);
    Response msg = (Response) response;
    System.err.println("size of results of wogolo:"
            + msg.getFlights().getFlight().size());

您可以使用以下代码,您不需要在xml文件中定义任何内容.

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

            WebServiceTemplate webServiceTemplate = new WebServiceTemplate(
                    messageFactory);
            Jaxb2Marshaller marshaller = new Jaxb2Marshaller();

            marshaller.setContextPath("PACKAGE");
            marshaller.afterPropertiesSet();

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

            Response response = (Response) webServiceTemplate
                    .marshalSendAndReceive(
                            "address",
                            searchFlights);

            Response msg = (Response) response;
        } catch (Exception s) {
            s.printStackTrace();
        }

要将不同的SOAP请求发送到不同的SOAP服务,您只需要让WebServiceTemplate知道它必须处理的所有请求和响应.

为每个请求和响应创建一个Java类,如下所示:

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;
    }
}

(@XmlRootElement是因为我们在下面使用JAXB marshaller;有关更多信息,请参阅Jaxb参考).

模板的设置就像这样完成:

    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"是Request/Responses类所在的包的名称,因此jaxb可以找到它们.

然后,您只需实例化要执行调用的类的请求,如下所示:

    // 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);

同样,您可以将响应对象强制转换为上面定义的JAXB类.
