How to create programmatically a spring PublishSubscribeChannel -

i want create programmatically following xml config

<int:channel id="sample"> </int:channel>

what can following

publishsubscribechannel channel = new publishsubscribechannel();

but there no method assign id.

actually <int:channel> produces directchannel bean.

and if want programatically , have entire messaging infrastructure should configure bean anyway:

@configuration public class myconfiguration {     @bean    public messagechannel sample() {        return new directchannel();    }  }

the id attribute key feature of spring ioc container and, of course, isn't responcibility of concrete class.

seems me should take new stuff of spring integration 4.0.
