Sure, you use a lot of frameworks - in parallel. But that's not what happens in Spring land. Instead, you get one framework (Spring) offering you an abstraction behind which another framework lurks, for things as large as say an ORM. Something that complex can of course not be hidden behind mere 1000s of Java interfaces, it all leaks horrendously and you find yourself "reaching through" the layers.
