As expected... It's the best... Really! Thank you, Tobi, for the lecture that is worth watching over and over again! I first encountered Spring Boot through Tobi's lecture, and the barrier to entry that I felt was too difficult was gradually broken down. When I looked up parts that I didn't understand, the parts that he explained in the middle were also really good, and for me who is still lacking and lacking, this lecture was indispensable. In my field, I kept hearing compliments that I had seen the lecture and that it was really good, and I wonder if it is right to call it the history of Spring Boot(?) I really, really liked that he even taught me those parts! There are some parts that I uploaded the review late, and there were some parts that I wrote briefly, so I added more information and wrote it, but it was an honor to be able to listen to the lecture! I look forward to the next lecture!
