I can't believe I've just wasted 2 DAYS of my vacation to properly configure logging in my project...

2 fucking days!!! For something as trivial (yet vital) as logging!!!

FUCK

Can someone explain to me Java lighting...

There log4j, slf4j, logback. Some are interfaces, others are implementations.

What is the setup so I can basically wit one and forget, or upgrade with the jar amount of code changes?

I need to upgrade log4j 1 to 2 and they changed the package name and how to init it....

Now it's logging.log4j.

And correct me if I'm working, Logger logger = LogMagager.getLogger(Clazz.class)

Does the log4j.properties need changing as well?

I fucking hate spring boot. I can go unwind and nobody would hear this but boy, does it suck. Every single thing about it is a pita. I spend 98% of time I should have used for feature implementation in JAVA, struggling and battling MUNDANE functionality of the framework that ought to be nobrainers

Today started out with a project I inherited. I don't even know whether to blame its original author but he installed a couple of funny libraries for logging. The spring app doesn't build yet gradle build completes successfully. No errors are logged to the terminal, just reams and bundles of json. WHY IS THE APP NOT BUILDING??? You want me wrangling json through that pinhole console window?

I struggle with the yml settings, none works. Eventually get rid of the package (hint, it wasn't the slf4j one). I'm able to debug app not starting now, but now live reload doesn't work

I copy configs from a previous project where it worked into this. Nope, doesn't budge. Eventually enable an ide setting but now server restarts twice after file changes. The implication is that request argument annotation no longer works! So the server just restarts and has amnesia about argument type resolution

I've been sitting here for hours, without implementing a single new feature. Everything is a painstaking, avoidable aggravation VS the "framework". Never seen anything as horrendous. No line of java code yet. I just want to send a request, retrieve parameters and verify live reload is "up and running". You'd think something as low level as this shouldn't take more than two minutes. Alas, welcome to the incredible world of spring development
