Thank you so much for your great lectures, Younghan. Please record the restApi design lecture and the lectures you are thinking about(?). I would be so grateful if you could. It's better because you teach directly based on what is used in practice (service) than studying alone, so I feel like I can escape from wandering around in various books that seem to grasp at clouds and study more efficiently. It's a great help in establishing the framework. Please record lectures on not only Spring but also JPA and everything else that Younghan knows(^^;)!! ㅋㅋ Thank you!^^
