Spring boot specifically; regular Spring is relatively ok. I'm using it professionally at the moment. It's just impossible to find where anything is coming from or understand how your application is wired up, because everything magically appears based on what's on the classpath - it's like the COME FROM statement joke. Even just changing your dependency versions can suddenly radically change your application's behaviour (e.g. now it's suddenly running a webserver).
I don't understand why is it better to have something wired up by annotations than explicitly writing java code. Is 'new' obsolete? At least tools (including IDE) can look for method calls, annotation strings not so much.
I'm completely baffled by the popularity of Spring.
That is true, there's a lot of "magic" that comes with boot. It can be helpful to take a look at what all of that auto-configuration code is actually doing, but reading that stuff is pretty difficult as well.
