Finally, I finished queryDsl! I was thinking of finishing it and reviewing the necessary parts while working on my personal project, but as I listened to the lectures following the roadmap, I thought, "Oh, I think we did this in the last lecture. I paused and wrote the code first and compared it. I reviewed a lot of it, so I was more satisfied. I had only written pure queries with mybatis, but while learning Jpa and queryDsl, I thought it would be better to use mybatis as little as possible. The ability to do dynamic queries with Java code and catch grammar errors at the compile stage was the biggest merit for me! Now, as I prepare my portfolio, I will apply what I have learned and make it my own as much as possible. Thank you!
