adragon1730's honest review, Setting up a Spring framework development environment and refactoring Dao course

I was able to clearly understand the Spring environment setup, and I had a chance to get a taste of JPA. The video was made in 2017, but Spring Boot Spring Data Jpa(1), (2) is a bit different from the current 2020 version, so it was a bit difficult to follow. Also, when I first started the lecture, I downloaded Intellij community and proceeded, but the last two lectures seem to have been conducted with Intellij ultimate. When creating a project, spring initializer did not exist, so I was confused for a while, and then I found out that it was only provided in the ultimate version, so I quickly changed the version and continued the lecture. If information about such details had been provided, beginners would be able to listen to the lecture more easily.
