[Springframework-developer] ServiceLocatorProxyFactoryBean

[Colin S. <col...@ex...>]

A few days ago I checked in ServiceLocatorProxyFactoryBean. I originally 
did a prototype version of this prompted by a  couple of weblog entries 
by Mike Spille:

Basically, the idea is that if somebody doesn't want to use the existing 
lookup method injection, because it seems too 'magic', they can instead 
define service locator interfaces like

interface TestServiceLocator {
  TestService getTestService();
}

or

interface TestServiceLocator {
  TestService getTestService(String id);
}

Then the proxy factory actually creates an a proxy which implements the 
interface to internally do a normal getBean call and returns the object. 
This proxy can be injected into the client code to be used as needed.

I put it in
  org.springframework.aop.beans
since it depends on AOP classes. In some respects, that's not a great 
package, since this is not at all about AOP or even a generic proxy 
mechanism, but if it was included in the normal beans hierarchy it 
wouldn't have the dependent classes included with it in the base jar..
