I received government support and completed the Java class, but due to personal reasons, I'm studying Java and JSP again now that a year and a half has passed since I started working, and I thought it was not enough for me to get a job, so I decided to learn Spring again, and I visited various blogs and read books to study, but I couldn't understand the words DI and AOP because they came up a lot. At that moment, I thought about watching an online lecture, so I came to Infraon and happened to watch this lecture. The explanations were really good, and I understood everything very well because I coded everything first and explained it one by one. What I especially remember is the DB access technology that you taught me here. What I learned at the academy was pure JDBC, which is used by developers at the ancient times, as the instructor said, but I was really surprised and shocked that I could solve it so easily. I really want to watch the remaining roadmap lectures in order, but I have financial problems right now, so I'll create a Spring project with my limited skills, get a job, and then buy the Spring Complete Conquest series ㅠㅠ At first, I thought it was expensive when I looked at the lecture roadmap, but after watching this lecture, I thought it was a lecture that I absolutely had to buy and watch even if it costs about 200,000 won per lecture. Thank you so much for making such a great lecture. I'll study hard and try to become a good developer ㅎㅎ
