I realized that the Spring studies I had previously had too many outdated technologies...ㅠㅠ Since this was my first time preparing for a job, I was doing this and that and eventually realized that I needed Spring first, so I learned about Mr. Kim Young-han's lectures and signed up for all the courses according to the roadmap!!! Thank you! I have now completed the basic course, but I will review it over and over again to definitely acquire it and master Spring! Thank you so much~ I will ask for other lectures!
