I was making a project after reading the Spring Basics and using only the basic settings of Spring 5, but I encountered many unknown bugs (interceptors not working, session-related issues, etc.) so I stopped the lecture and finished it in 5 days to build it up again from the basics. Now, I will challenge myself to complete the project using only the basic project settings and the view page provided. Some of the advantages I felt while taking the course are: 1. It seems that the lectures were well prepared in advance and recorded. (Refreshing without any lag) 2. Although it is not frequent, it does a good job of explaining troubleshooting for special errors that are not often found in the basic book. 3. The mini-projects are better than expected (beyond the simple bulletin board CRUD that is often found in the basic book, it includes file attachments, paging, and although not much, AJAX.) 4. Before proceeding with the mini-project, when explaining the functions or custom tags provided by Spring-MVC, the project is always created independently (I think it is a consideration for students who read it as a manual book.) However, I am not sure if it is because it is made for intermediate users, but there is no mention of the idea of why a certain method was used for a certain process. However, even considering this, it seems certain that it is a lecture without any shortcomings.
