Design Pattern in spring

I found a lot of documentation on patterns for various languages ​​but also how to use it on different frameworks, but apart from a few examples to explain what it consists of I never had the impression that they were used outside of an academic context. After all, over the years I have never seen the application of a pattern in real cases unless it was used internally in some framework. Since I consider design patterns an excellent approach for solving various cases, I would like to put some real cases that I had to face with the application of the relevant pattern under Spring (which, alas, although I found various articles, the impression they gave me it was as I said only for academic spirit and not for use in real cases). I hope that these examples with the pattern approach can support those who may find themselves in the same situations and be an inspiration to apply them in their contexts too.

Remember: Only Pattern gives you the strength and endurance that you need
