I used Spring while working on a project in a national course, but I was pressed for time and couldn't grasp the principles at all, so I was only in a hurry to implement the functions, so I took this course to build a solid foundation. Through this course, I was able to understand the essence of Spring?, and I'm going to analyze the project code again with the concepts I understood. Thank you so much for providing such a great course, and I will trust and listen to the MVC course!
