When I decided to study Spring, I first looked for various books. However, the books were too long, and even the books that I could follow along with did not properly explain what was going on, so I could only follow the code. Even in the middle, there were parts where the version changed or I got stuck, so I couldn't proceed any further and stopped. So I looked for a way to quickly study the overall Spring development while actually making it, and I ended up listening to your lecture! You explained so kindly the parts I didn't know when I read the book, and you even explained shortcut tips and why things should be implemented this way so well that I was amazed the whole time I was listening ㅠㅜ!! The lecture materials were so good, and I'm really thankful that it's a free lecture ㅠㅠㅠㅠ!! I really recommend it to people who are new to Spring! I want to study in more detail, so I plan to take the next lecture. Thank you so much for the great lecture^^
