This Spring Data JPA lecture is also a great lecture!!! The part that I was most satisfied with was the part where he explained how convenient it is to use Spring Data JPA by showing the process of implementing it using the existing JPA through live coding and modifying it to Spring Data JPA, and I couldn't help but admire how much experience and knowledge Younghan has about the technology. The only regret is that Younghan's unique humor that he showed in the previous lecture was not shown. It was one of the elements that made the lecture fun, but it was a little disappointing..ㅠ Nevertheless, he explained well what is used in practical experience and practice and what is not, so I learned which parts I should focus on studying and using. I'll see you in the next Querydsl lecture review :-)
