Following the introduction to Spring, I also completed the core principles basics. As a non-major, I had many difficulties learning Spring. At the academy, rather than the basic principles, they only said that if you follow the written code, you will naturally understand it, and I was just accumulating questions like, 'Why does this work like this?' Also, when I tried to learn from other sites, the videos were recorded several years ago, so they were somewhat out of touch with current trends, and the explanations of the operating principles were lacking, so I always felt regretful. In the meantime, I happened to see Kim Young-han's lecture on Infraon and started taking the introductory course. Not only did it cover the basics of Spring, but it also provided detailed explanations of how it is applied in practice, so I felt like the frustrations I had been experiencing were resolved. It's still lacking, but as you said, I plan to continue learning with the wild type, and I will slowly review the core principles basics to solidify my foundation. Thank you for the great lecture, and I look forward to the additional Spring lectures that will be released in the future~! (Usually I don't write reviews or comments after shopping or reading articles, but I heard that class reviews are helpful, so I tried my best to write them. Haha)
