JPA is applied to the company, but there are a lot of parts that are applied incorrectly, so I am studying and working on it at the same time. I am working overtime to solve the parts that are not working properly or are working strangely, and when I come home and turn on the lecture, It is so scary to see the things I dug up in the evening come out smoothly in the video as if it were a lie. I am about to wear out from hitting my knees. My heart is pounding~~~~ How can you lecture so well??????????? Ha..... I am going to listen to the rest...
