Transforming spring-ws implementation to spring-integration-ws implementation - spring-ws

Question

I have an implementation of web service (server side) using spring-ws. I would like to change my code to use spring-integration-ws (ws:inbound-gateway and channels). I have tried examples but still not sure if it is possible to transform my implementation. In short my I am using #Endpoint, #PayloadRoot, PayloadRootAnnotationMethodEndpointMapping and JMS (as transport). Please find below my implementation:
The endpoint class (MyEndpoint.java):
#Endpoint
public class MyEndpoint {
#PayloadRoot(localPart="getUserRequest", namespace="http://play.zahid.springint/Jibx")
public GetUserResponse getUserResponse(GetUserRequest request){
log.info("Start getUserResponse " + request);
GetUserResponse response = new GetUserResponse();
User user = new User();
user.setFirstName(request.getFirstName());
user.setLastName(request.getFirstName() + " Last");
response.setUser(user);
log.info("End getUserResponse " + response);
return response;
}
#PayloadRoot(localPart="sayHiUserRequest", namespace="http://play.zahid.springint/Jibx")
public SayHiResponse sayHiUserResponse(SayHiUserRequest request){
log.info("Start sayHiUserResponse " + request);
SayHiUserResponse response = new SayHiUserResponse();
response.setResponse("Hi " + request.getFirstName() + " " + request.getLastName());
log.info("End sayHiUserResponse " + response);
return response;
}
}
The spring xml file (applicationContext.xml):
<bean id="listenerContainer"
class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory" ref="mqCachedConnectionFactory" />
<property name="destination" ref="defaultDestination" />
<property name="messageListener">
<bean class="org.springframework.ws.transport.jms.WebServiceMessageListener">
<property name="messageFactory" ref="messageFactory"/>
<property name="messageReceiver" ref="messageReceiver" />
</bean>
</property>
<property name="concurrentConsumers" value="1" />
<property name="acceptMessagesWhileStopping" value="false" />
<property name="recoveryInterval" value="10000" />
<property name="cacheLevelName" value="CACHE_CONSUMER" />
</bean>
<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory" />
<bean id="messageReceiver" class="org.springframework.ws.soap.server.SoapMessageDispatcher">
<property name="endpointAdapters">
<list>
<bean id="endpointAdapter" class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
<constructor-arg ref="marshaller" />
</bean>
</list>
</property>
</bean>
<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping" />
For simplicity purpose I have removed the unnecessary codes and xml configuration.
Is there anyway to keep my endpoint class (MyEndpoint.java) as it is and use spring-integration-ws support (ws:inbound-gateway and channel)?
Let me know if you need any more information.
Thanks

Yes you can.
I'll try to explain a simple integration-ws implementation for your situation:
applicationContext.xml:
<bean id="endpointMappings"
class="org.springframework.beans.factory.config.ListFactoryBean"
lazy-init="true">
<property name="sourceList">
<list>
<ref bean="uriEndpointMapping"/>
</list>
</property>
</bean>
<bean id="uriEndpointMapping"
class="org.springframework.ws.server.endpoint.mapping.UriEndpointMapping"
p:defaultEndpoint-ref="ws-inbound-gateway">
<property name="mappings">
<props>
<prop key="${yourEndPointUrl}">ws-inbound-gateway</prop>
</props>
</property>
</bean>
<int-ws:inbound-gateway id="ws-inbound-gateway"
request-channel="ws-request-channel"
reply-channel="ws-response-channel"
error-channel="ws-error-channel"
marshaller="marshaller"
unmarshaller="marshaller"/>
<int:channel id="ws-request-channel"/>
<int:channel id="ws-response-channel"/>
<int:channel id="ws-error-channel"/>
<int:chain input-channel="ws-request-channel" output-channel="ws-response-channel">
<int:service-activator ref="yourBean" method="getUserResponse"/>
</int:chain>
There are some points here.
You need to define a bean, MyEndpoint type, I named it yourBean here.
yourEndPointUrl defines your end point URL for getUserResponse method.
I've defined service-activator inside a chain, you can add logging or another thing inside this chain to enrich your handling mechanism.
You also need to have a router for routing your requests in to different methods of your bean.
