I can see that the dependency injection annotations can be complex for people not experienced with the whole Spring/IoC/DI setup. I have some rules and general guidelines I use for keeping them in check which I can explain in about 10minutes (and have done to team members in a few companies) Honestly, I prefer to debug with annotations and a debugger over a manually coded configuration class with hundreds of lines of wiring components together. And for removing the other annotations: Why should I decouple apidocs from my code? They are litterally annotating the source code so it makes sense to have them close. Stuff like the validators and JSON properties and configuration also makes sense to have them close to the fields that they are about instead of in a separate JsonSerializer class or whatever.
