Thank you for the great lecture! You said what I wanted to say in the last lecture, Daum. When I first listened to the instructor's previous Spring and JPA lectures, I thought that even if I didn't completely understand them, I would learn them through projects and review them through the learning materials again, so I listened to them until the end. And I've recently realized that I was right. I was surprised that you said this in Daum. LOL. This lecture really helps me study deeply even when I watch it over and over again. Thanks to you, I was able to study Spring and JPA in depth, so I'm really grateful. I think this lecture felt a little different from the previous lectures. I could understand the content with my heart, but it was a lecture that I couldn't convince with my head. I think it's because I'm an immature college student who wants to be a backend developer who has never experienced a project that deals with Spring AOP in depth, and I still haven't found a clear answer to how I can utilize this in an actual project. But as I said before, even if you don't understand it at first, if you listen to the end and come back and study, I think you will realize that it was a really deep, necessary, and helpful lecture, and I think you will find the answer that I couldn't find. Thank you for the great lecture!! I plan to review the content again this week. I think it would be better to review the advanced content and then review the DB 2 Spring Transaction Understanding ~ Spring Transaction Propagation 2 again. After reviewing like this, I plan to move on to the last remaining Spring Boot lecture. Thank you for the great lecture as always. I still have a lot to learn and a lot to learn, but if I study slowly and deeply and gain experience through projects, I believe that I will definitely be able to become a good developer and grow. Thank you for always cheering me on!!
