Hello, I am a student who came here through YouTube. The lecture that expands the concept by adding flesh to the basic principles is the best. I didn't know it would be inconvenient to do MVC2 without Spring, so I just thought it was like that. But after completing this lecture, I realized that... this is why I use Spring. Spring felt difficult and was really annoying to do, but my thoughts changed in just a week. Thank you. Then I will move on to Spring MVC. Shhh~~~
