I took 8 lectures from Spring Introduction to MVC2 for 7~8 months, and then from JPA Basics to JPA Practice 2. It took some time because I had something to do, but looking back, I think I really grew a lot. In the past, I had a hard time implementing even the most basic things in Java and couldn't do a proper project, but after learning from Younghan, I feel confident that I can create one page with Spring + JPA :) Although I still have a lot to learn, I will study JPA more by reviewing the previous ones and doing a toy project, and then I will come to take the Spring Data JPA lecture. Thank you always. I will definitely come to take the Data JPA and QueryDsl lectures!!
