MethodEndpointMapping

[dhol68]

Hi,

Is it possible to handle multiple requests in one endpoint without annotations?

[Arjen Poutsma]

Theoretically, yes. In fact, in the sandbox, there is a MethodEndpointMapping which does this: the SimpleMethodEndpointMapping. The idea is that you define a method prefix, and possibly a suffix, and register endpoint beans with that mapping.

So if the prefix is "handle" (the default), and the incoming message has a payload root called <GetFlights xmlns="http://something">, the handleGetFlights method is invoked.

If you create an issue, I can move this mapping from the sandbox.

HI,
SWS-129 created.

Thank you!

[Arjen Poutsma]

Done. I've also moved PayloadMethodEndpointAdapter and MessageMethodEndpointAdapter from the sandbox, so that you can have methods like:

Source handleMyMessage(Source request);

 
void handleMyMessage(MessageContext request);

These adapters are loaded by default by the MessageDispatcher, because they don't need any additional configuration.

Hi Arjen,

I'm very interested with this MethodEndpointMapping, but still confused.
I would like to have something like this :

<bean id="methodPayload" class="org.springframework.ws.???">
   <property name="mappings">
       <props>
           <prop key="{namespace}GetMethodARequest>myEndpoint</prop>
           <prop key="{namespace}GetMethodBRequest>myEndpoint</prop>
       </props>
    </property>
</bean>

<bean id="myEndpoint" class="com.mycompany.MyEndpoint"/>

But this is where I'm stuck ...
Is it possible the "methodPayload" bean defined as above ?
What would be the MyEndpoint class extended from ?

Thanks.

Your class doesn't have to extends from anything, it can be a POJO. The idea is to write a class like such:

public class MyEndpoint {

  public Source handleMyMessage(Source request) {
    ...
    return response;
  }
}

and wire it up as follows:

<bean class="org.springframework.ws.server.endpoint.mapping.SimpleMethodEndpointMapping">
  <property name="endpoints">
     <bean class="something.MyEndpoint"/>
  </property>
</bean>

As a result, the MyEndpoint.handleMyMesage will be invoked whenever a message comes in with MyMessage as payload root local name. So it's more convention-based, though you can define the prefix and suffix the SimpleMethodEndpointMapping looks for (by default "handle", and an empty string respectively). There is no way to map namespaces: like the name says, it's simple .

Thanks Arjen for your reply.

Maybe I miss something, I did not find SimpleMethodEndpointMapping class, where is it ?
Why there is no interceptors properties as in PayloadRootQNameEndpointMapping or in SoapActionEndpointMapping ?

Thanks.
