Thank you for the great lecture. While listening to the lecture, it was a lecture that stacked the brick stacks needed to build a building called a web developer one by one. While doing a simple toy project, I will review the Spring core principles basics ~ MVC 2 and have time to reorganize before moving on to the next DB part. And I thought I was a wild type, but I realized I am a scholar type.. ㅎㅎ;; I will listen to all of DB 2 and listen to practical JPA. Thank you for always cheering me on!!!
