Also, do y'all call main() in the if block or do you just put the code you want to run in the if block?
Enough of that crazy talk - plainly WheeledDeviceServiceFactoryBeanImpl is where the dependency injection annotations are placed. If you can decide what the code does without stepping through it with a debugger, and any backtrace doesn't have at least two hundred lines of Spring boot, then plainly it isn't enterprise enough.
Fair enough, though. You can write stupid overly-abstract shit in any language, but Java does encourage it.
