I learned Spring at the academy, but I didn't know why I had to use it because I was doing get mapping, empty injection, and adding dependencies without a big picture. ㅠㅠ I just followed the academy teacher's code and when I actually started the project, I didn't know where to start. So I looked for a lecture, and while taking the teacher's class, I was able to completely understand it. It was really good because he gave me a big picture of how it works and explained in detail why I had to use it!!! I've taken a lot of Inflearn lectures, but this is my first time leaving a course review... I'm really so impressed with your lectures. Please make lots and lots of lectures in the future. ㅎㅎㅎ Even though it's a free lecture, the quality is at this level. I'm looking forward to the other lectures. Thank you so much, so much!
