I will write an honest review hoping that it will be helpful to others. Before I say anything, I am a college student who has studied two introductory Java books and knows SQL. In fact, I don't know much about this course to the point where I wonder if it is a course that I should take. It is easy to follow from MVC to DB settings, but I don't know why it is done that way. It feels like I am learning technology without any knowledge? Yes. Of course, it seems that the instructor provides sufficient explanations of what is being done, but even in those explanations, basic knowledge is omitted. For example, if you say, 'This code is a container Spring bean~~ ...', I feel that this code does that, but I still don't know what a container is and what a Spring bean is. It feels like I am just adding a spoon to a side dish that someone else has already prepared. It is a good lecture to experience Spring firsthand, but it is not enough to explain each lecture to others or to do a project with Spring. Of course, this lecture is free, the lecture time is very short, and it is not a lecture that goes into Spring in depth, but I feel a sense of self-loathing because I just follow the code without knowing anything. I have a strong feeling that I should have studied JSP, servlets, etc. much more deeply?
