I'm not sure who the fuck implemented the error handling of spring boot but goddamn he/she needs to be fired. Why the fuck does the application return a weird error about a setting not being set when it can't connect to a database?? Wtf took an hour to solve and that's not the only thing I hate about spring boot. Why is the documention utter garbage, why do I have to rely on tutorials and can't I just read in the documentation how for example the http rest mapping works. Now I have to cross-reference multiple tutorials to find the best way because guess what there are multiple ways to do something in this framework and some tutorials don't even work.
