Hello, instructor~ I took the instructor's free spring concept lecture on Inflearn and liked it so much that I decided to take the class. I also took the instructor's metacoding YouTube and easyup class. For reference, I think it would be helpful for others to take the easyup class JPA lecture. In the easyup class, the lecture is given using JPA Eclipse, and I learned a lot of things I didn't know, which was good. The voice is calm and nice, and the principle and concept are explained calmly and well. I also look forward to more in-depth parts related to spring. JPA intermediate/advanced, concurrency control (lock), parallel processing, batch, excel file processing, email transmission, remote control, etc. I look forward to good lectures in the future. I support you. Always stay healthy and happy^^
