After finishing the basics, I finished JPA Utilization 1 and watched all of the 2 parts. The taste of applying the knowledge I acquired while learning and progressing through toy projects one by one is really amazing. I bought both Spring Data JPA and QueryDSL, and I think I will be able to raise my JPA to a certain level if I watch them all. I felt for the first time that he is not a god-young-han. Thank you for creating such a great lecture.
