Answer 1

You can create an abstract bean definition, and then "subtype" that definition, e.g.

Strictly speaking, the definition for b doesn't even require you to specify the class, you can leave that out:

However, for clarity, and to give your tools a better chance of helping you out, it's often best to leave it in.

Section 3.7 of the Spring Manual discusses bean definition inheritance.
