Spring is written by a committee of junior developers trying to implement the ideas from a committee of slightly less junior developers. Which is to say it's a huge unintelligible mess. As the other commenter attest, it works really well if you need the one thing it does - unfortunately the moment you need something slightly different you are forced to dig deep into the insane internals and it is a disaster. This moment comes very quickly too in every project because it was written by people with no experience in real projects.
