It's probably a waste of time and money. Just read the free documentation for spring, it has everything you need in there. And EE applications are def on the way out. It's all spring boot, unless you're working on old stuff.
I agree that old tech will have EE in it for a long time. But all the docs for EE are also free to read and learn on your own. The best skill you can have when being a programming is self learning/teaching.
