I first bought Spring JPA for employment and listened to it, then I bought the Spring Basics after playing around with it. The instructor said that if you do this in practice, this is how it will cause problems, and there were errors that I experienced, so I really laughed while watching it! And I think I enjoyed it more because I could see the instructor's love for this Spring lecture from his expression. I will also look at the rest of the roadmap. Thank you!
