It was great that it clearly covered the practical skills of Spring Data JPA, what not to do, and which parts not to use.

I strongly felt that the difficulty suddenly increased starting from Order Inquiry V4, but practice makes perfect - I'll quickly watch the next lecture and come back stronger after reviewing from the basics again.

Going through Java -> DB -> MVC -> JPA in order, moving from recent -> past videos, there have been many ups and downs, but believing that "old is gold" and that current technologies must have originated from past ones, I'm working hard at it.

I learned Java well and it was helpful, and the database course is also being very helpful!

I trust Younghan hyung!

It seems like the core parts of frameworks have always been difficult to access. At work, I'm developing using frameworks in other languages, but I only had a shallow understanding of how they actually work. If I hadn't come across this course, I would have glossed over Spring the same way;; Some parts I understood right away, but there were parts I didn't, so like borrowing books from the library, I plan to come back and listen again when I need to. Thank you so much for another excellent course. I feel like I studied with great satisfaction and enjoyment. I was planning to take the MVC course next, but as you recommended, I'll tackle the JPA practical application course first. Since I work in e-commerce, it should be quite interesting. Thank you in advance for that as well^^ Stay healthy~!

Hello, I'm a student who will be entering 10th grade! I watched from the beginner course before and left a review, and now I've finished the basic course! Even though I'm not a job seeker, I started taking this course because I want to major in computer science, and it was truly an excellent lecture ^ㅡ^ As I mentioned before, I've already purchased all of Intermediate 1, 2 and Advanced 1, 2, 3. I'll complete each course and leave reviews again. Thank you so much for having someone like this (bow)🙇

I love it so much

I enjoyed this lecture as well. Although Spring is still unfamiliar and challenging for me, I'll review it whenever I have time. I'll definitely come back later to take the rest of the Spring roadmap courses. Thank you always for the great lectures~

I can feel that most of Younghan's lectures try to explain things as easily as possible. Still, as someone encountering threads for the first time, there were some difficult parts, but I feel that reviewing and revisiting them when needed should resolve things to some extent. For example, I was confused until I gained the insight that "the difference between having and not having a Future is that Future is necessary because performance degradation can occur depending on when blocking happens during execution and result return." Among the areas where threads are utilized, I still don't know what technologies Spring uses to leverage multithreading or how the principles work. I hope this will be helpful when I study Spring or computer-related topics in depth later on.
