Spring is for the lazy. Fundamentals, basic concepts and examples with code. Part 1.

Many people, after reading my articles about creating a template for a web project and about creating a simple web service on servlets , wondered when I would write about spring. I didn’t want to, I suggested reading a book (and I still say that a book is better than 10, or even 100 articles on the Internet). But now I’ve decided that explaining the same thing to different people, I spend more time than if I sat down and wrote an article once, and then just sent them a link. So I’m writing for the sake of the link))
