The only thing I was able to find on this is chapter 188.8.131.52. "Refreshable beans" in the Spring manual. But that's using dynamic languages such as Ruby or Groovy.
What you could do is provide a Refreshable interface, implement the refresh behavior and write a method that gets a bean, tries to cast it to a Refreshable and if succeeds, calls the implemented refresh method.
This, by the way, is more a general Spring question and isn't RCP specific. You could try to ask this question in the general forum.
