Kim Young-han, knowledge sharer, thank you for always giving great lectures ^~^ I gained a lot from this lecture, but the best thing is that, as you said, I am building a solid framework so that I can judge for myself how much I know. Thanks to you, I am gradually gaining confidence in my expertise as a developer!! Now, after listening to the next Spring MVC Part 2, I expect to be able to do more things using Spring, and I will continue to move forward. Thank you!!
