Because of the Lunar New Year holidays and business trips, it took much longer than expected, and the period was extended by that much, so I couldn't focus and listen to it in a short period of time, and while listening, I went back and looked it up and listened to it, and I went through the difficult process once again. What I always feel is good about the lecture content is that rather than directly teaching Spring's unique technology, as the instructor said, it is a way to understand how the technology was coded before and how easy it is to code in Spring. Of course, as someone who is currently listening to the instructor's lectures one by one, when I meet an actual service after learning all of this, I haven't seen the big picture of where and what to take and use, so I don't immediately understand the application point in the field, but the instructor's lectures are not about grasping at clouds, but rather about creating a project in a hands-on manner, so the lectures are structured with the most feasible code possible, which is very helpful. Aside from those who are employed, there may be those who listen to these lectures and go on to create their own services. As the culmination of your lectures, how about producing a lecture that shows the process of creating a service by personally carrying out a project from start to finish...????
