It's a good lecture. I liked that the instructor selected only the most important topics from the reference and explained them. I used to get tired of reading thick Spring books. Spring Boot is easy to use, but it was good to study the main topics selected by the instructor with examples. I understand it well and I don't think I'll forget it easily. I was also able to learn simple docker usage in the middle. Personally, I feel good because I studied well at the end of the year. I'm planning to start a new toy project in the new year, and I think I'll be able to use Spring Boot. Thank you.
