This is probably the most fun programming lecture I've ever taken. I listened to the parts I didn't understand twice, and I still felt like something was missing, but I decided to listen to the entire Spring MVC lecture once and quickly go over the core principles again!! If you're having trouble choosing a Spring lecture, hurry and buy all of Instructor Kim Young-han's lectures!!! These are high-quality lectures that you won't feel like you wasted your money on. (+Unlike other lectures, he answers questions really quickly) Thank you, Instructor Kim Young-han!!!
