This sounds a bit negative but at the same time not purely related to Spring but rather to the choices of external dependencies. I've worked using Spring for years and it makes me smile reading it.

Hibernate looks easy but the abstractions have a cost associated with using and maintaining it. There are a lot of settings you need to get right. There were dedicated DBAs that would optimize it in the past. You could just use JPA to make the life simpler.

Tomcat.. I mean why? It was great but I'd say it maybe went out of pace compared to everything else. Why not embedded Jetty. At this point I'm starting to have doubts about how you deploy the services to begin with.

Dependency injection is actually great albeit the usual problem is that you need to read books to understand it as there is more than one way to do everything. My pain point was usually related to the differences you need to do among Java, Groovy, Kotlin but otherwise it is awesome.

Flask is shite, basic, Python has a hard time solving its mess with dependencies and its multithreading support is meh. Go is great I love it. But if you want to create enterprise software, Java ecosystem has you covered and the engineers are cheaper to hire.

Yeah, I'm also heavily ranting. My nick is meant as a hint haha. In the end and after quite a few years we're almost at a point where we love to work with our stack, minus the occasional weird funky thing happening because of the ecosystem (which would never happen in something like Go for example!). Hexagonal + Kotlin + Gradle multi-modules is a beast!

> My pain point was usually related to the differences you need to do among Java, Groovy, Kotlin but otherwise it is awesome.

Yup, agreed! We got to run kotlin pretty nice and got to play it together nicely with gradle convention plugins.

Agreed on Python. Was my first properly learned language back in the days and my first backend lang. Absolutely annoying. I also love go, but it lacks something like gradle, especially multi-module support. I love it but don't see it on a scale as our Kotlin codebase.

> engineers are cheaper to hire

I think there's also the benefit of an exotic language. You might only get 10 CVs, but you could probably hire half of them because only passionate people bother to look into exotic things. With java you have a bigger bandwidth ... which causes a lot of work.
