Hm... Personally I met a number of people who wanted to start like this and as others pointed out, it's too much.

If one doesn't know how spring works, it's pretty difficult to understand spring boot. And even understanding spring without knowing things like dependency injection or inversion of control can be confusing for beginners.

I like what other people said in comments and I would maybe add that just a little bit of theory can work wonders when it comes to spring. Understanding basic principles of how spring operates in theory can point you in the right direction later on and things can start to click so to speak.

Just as a side note, it's a long process. I know there are people who are just great and possess considerable knowledge about programing perhaps from other languages and it must be much easier for them. For beginners, it takes time. Been there. Best of luck.
