Hello. ppj2130, this lecture is a lecture that quickly explains what Spring is in general. Therefore, rather than understanding it in depth, you only need to understand that "Oh, Spring does this." I recommend reviewing it once. Additionally, if you are weak in the basics of Java, it may be difficult to understand. Thank you.

Haha.. Rather, I think the next one is easier to understand than the first one. Or is it because my skills have been built up? I feel like I'm growing while watching Younghan's lectures, and it gives me a sense of accomplishment and it's good. I'll keep fighting in the future. Thank you.
