将Spring-ws webservicetemplate请求以XML格式保存到数据库

Question

I am trying to save Spring-ws webservice template request to DB so that I can resubmit the same Webservice request when corresponding site is up.

My configs are as below

<bean id="serviceMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="contextPaths">
            <list>
                <value>com.XXX.XXX.ws.XXX.submitorder</value>
            </list>
        </property>
    </bean>

I have a XXXIntegrationClientImpl.java

private static final ObjectFactory  XXX_INTEGRATION_LOOKUP_FACTORY  = new ObjectFactory();
com.XXX.XXX.ws.XXX.submitorder.PlaceExternalSystemOrder request = XXX_INTEGRATION_LOOKUP_FACTORY.createPlaceExternalSystemOrder();
// populate the request with all required values

The partial Source of PlaceExternalSystemOrder

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {"orderInfo"})
@XmlRootElement(name = "PlaceExternalSystemOrder")
public class PlaceExternalSystemOrder {...}

I cant modify above since it doesnt belong to us.

Below code doesnt work

JAXBContext context = JAXBContext.newInstance(com.XXX.XXX.ws.XXX.ticketinfo.PlaceExternalSystemOrderResult.class);
Marshaller m = context.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
StringWriter stringWriter = new StringWriter();
m.marshal(request, stringWriter);

Just wondering what's the equivalent of above to get request XML, so that I can re-submit the request

Answer 1

Turned out to be a simple solution, unfortunately couldn't find it earlier.

Key was to use Inject configured Jaxb2Marshaller!

@Autowired
private Jaxb2Marshaller     serviceMarshaller;

javax.xml.transform.stream.StreamResult result = new StreamResult(new StringWriter());
serviceMarshaller.marshal(request, result);
String xml = result.getWriter().toString();

Create your own "PlaceExternalSystemOrder" class with your own customized fields (xml elements).

Let say PlaceExternalSystemOrder2 , use the same annotations @XmlRootElement(name = "PlaceExternalSystemOrder") from the old class as needed and customize the class to meet the required Request parameters.

The steps would be like:

• Create new classes that maps the field to each XmlElements of the request

• Customize the new class "PlaceExternalSystemOrder2" ie add new fields, getters and setters, annotate the field or setters.

• Use the Class in createPlaceExternalSystemOrder

• Change the JAXBContext context = JAXBContext.newInstance(com.XXX.XXX.ws.XXX.ticketinfo.PlaceExternalSystemOrderResult.class) to use JAXBContext context = JAXBContext.newInstance(com.XXX.XXX.ws.XXX.ticketinfo.PlaceExternalSystemOrderResult2.class)

• Populate the Request object and pass it as request in your m.marshal(request, stringWriter); - NO Changes here.
