[Springframework-developer] Auto-wiring by type - too many instances when proxying?

[Mike Cannon-B. <mi...@at...>]

Hey guys,

Just wondering how you get around this scenario.

We were playing around with autowiring today, specifically using the 
ListableBeanFactory.autowire(Class, 
AutowiringBeanFactory.AUTOWIRE_CONSTRUCTOR, false) method.

Now the problem is that if I have two beans of effectively the same 
type (say SpaceManager) - the autowiring no longer works.

The reason we have two beans implementing SpaceManager interface is 
that there's an implementation defined with all it's properties 
('spaceManagerTarget') and then a transaction proxy factory bean 
wrapping the impl with transaction attributes ('spaceManager'). I think 
this is a fairly standard type of scenario.

However both are exposing the SpaceManager interface, hence the auto 
wiring fails.

What to do? Has anyone else faced this problem?

I never access the 'spaceManagerTarget' from within my application, is 
it possible to 'hide' this instance somehow?

Cheers,
Mike
