This is the main reason why I want this too. Spring reminds me if I try to
inject something that doesn't have a setter, I want it to tell me when I
forget to inject something too.

I don't want to pollute afterPropertiesSet with these kind of things. And
even if I did, I probably would forget to add checks for some attributes at
some point. It's more easy to remember to add something at the source, with
an annotation imho.

I agree. One size does not fit all.

Things like this would fit nice in a Spring Wiki Cookbook though...
