spring and interfaces

Question

I read all over the place about how Spring encourages you to use interfaces in your code. I don\'t see it. There is no notion of interface in your spring xml configuration.

Answer 1

it's easy to generate proxies from interfaces.

if you look at any spring app, you'll see service and persistence interfaces. making that the spring idiom certainly does encourage the use of interfaces. it doesn't get any more explicit than that.
