System oriented around methods

Hi,

I need to create a system oriented around Methods where providers can register for the Methods they handle and consumers can do two things (for now) - either get Metadata for a method or execute it. I'm considering creating a REST style architecture where methods are resources with unique URIs and an interface consisting of two methods - getMetadata and Execute.

I'll need to have an equivalent of @RequestMapping so that the provider that handles specific methods can be located by the central dispatcher. As a result the provider will return either Model or Metadata object.

This looks pretty similar to Spring MVC but I don't want to expose and consume my resources(methods) over the web and use http as this will incur unnecessary overhead. Instead I want to use it like a standard java API where java methods are called and java objects are transferred.
I can do that by writing my own equivalent of @RequestMapping and Dispatcher logic but I was wondering if there's a better way to do this with Spring. Any suggestions?

Thanks!
