If there are people like me who have never done Java or Spring before and have to do it, I think it would be better to start studying with this MVC lecture first rather than JPA utilization, and then listen to the 6th lecture of the relevant lecture and then listen to it from the beginning again. The lecture itself is informative and good!! I am always grateful to the instructor ㅠㅜ... That's it! This is a review of a beginner who started listening to MVC after returning from listening to JPA utilization without knowing anything.
