As always, the instructor's lectures were so good because I felt like my understanding of the technology was naturally accumulating. When I first encountered the web field, I encountered Spring MVC without even knowing JSP-Servlet. So, it was really painful because terms like Dispatcher Servlet and actual code writing seemed to be separate things. Through this lecture, I think I was able to properly learn the important concepts of Spring MVC. I think I will remember it for a long time because I learned it through upgrading the examples. Thank you.
