Spring Core Principles - Basics

When I first studied Spring, I didn't really understand why it was necessary, where, how, and when to use it, so I studied by looking for books, online lectures, and many other materials. If I had Younghan's lectures when I started studying Spring, I think the difficulties and hardships I experienced when I first studied Spring would have been reduced. It was the first time I saw a Spring lecture that started with object-oriented learning, and I think Younghan has an incredible ability not only in development but also in teaching. I was able to figure out what the core and essence are through Younghan's lectures, and I can't help but say that it's really amazing that he incorporates that into the beginning of the lecture. If you still don't understand the lectures after watching them all, or if you have doubts about whether the lectures are really good, study using books, the internet, etc., and then review them. As your horizons expand, you will understand things you didn't understand before when you watch them again, and you will feel that they were explained so easily (I think this is the advantage of online lectures, and this is my experience watching Younghan's jpa lectures..ㅎㅎ) Also, the bdd style, assertj, etc. covered in the lectures will seem unfamiliar at first, but if you Google the keywords that are given and study them, I think it will be very helpful. I look forward to the next lecture.

Where are you, Mr. Kim Young-han?? From now on, I will bow to you before I go to bed.. Thank you so much for the great lecture.

Do I need to say more? Excellent teaching skills, thorough lecture preparation, I don't think I've ever taken such well-prepared PDF materials or such a non-boring class while listening to an online lecture. If I had listened to this lecture when I was preparing for an interview before getting a job, I would have been like Lu Bu riding a red hare. I listened to the lecture well. I will go listen to the sequel as soon as it comes out!

I'm starting from Spring Introduction and taking the DB 2 lecture. I think I'll finish the roadmap soon. In fact, this is a review of the entire roadmap of Mr. Kim Young-han, but I wonder if it's right to leave it here in the basics, but I'll write it here anyway. Are you a junior with less than 3 years of experience? `Definitely` listen. I don't mean to look down on you, but is your company a small or medium-sized enterprise or SI? `Definitely` listen. Mr. Kim Young-han's roadmap is a masterpiece lecture that goes beyond simply providing knowledge and really levels up the mindset of a developer. Those who are developing in the field will agree. This job of a developer is actually a job where the gap in knowledge is really severe. In other words, smart developers are really, really smart. Ignorant developers, to be honest, are called coders, just copy and paste without thinking and work day after day. But the important thing here is that no one who is an ignorant developer wants to be an ignorant developer. Even though I know I am lacking, I still don't know how to study. I study by searching the Internet? Honestly, I think that is wrong. If you look at the things that come up on so-called technical blogs, there are some correct things, but there is so much incorrect information and so much fragmentary content that it is not helpful for serious study. Also, when I try to buy books and study them, they are all books that were published 2 or 3 years ago, and there are so many differences due to version updates and changes in technical specifications that I feel like I can't keep up with the trends. And in this situation, developers are also office workers and have to do their assigned work. They somehow make code that works and then move on to the next task... The daily routine repeats itself, and at some point, they become developers who just endure each day out of inertia. However, what I felt while listening to Kim Young-han's lecture was that I was deeply impressed as I realized the study method of 'how to study' to become a good developer. Also, during the lecture, you talk about practical problems and solutions, and other small tips.. I don't know how to explain this in words. It's really valuable know-how that you can't learn even if you pay money. I want to say that it's very valuable knowledge that allows you to learn how developers at top-tier IT companies, so-called Nekarakubae, think and solve problems. So, if you're preparing to get a job as a developer, you should definitely listen. I also recommend that people who are currently working listen. Sometimes, there are people who worry about the tuition.. Everyone's financial situation is different, so it's hard to say, but please listen anyway. You really won't regret it.. And lastly, Mr. Kim Young-han. Thanks to a teacher like you, even a developer like me was able to become a person. I hope you continue to do well and make many lectures..

Even when I was in middle and high school, I didn't like taking online lectures, but this lecture was really fun and easy to listen to. I can now understand and use functions that I used to use without even knowing the principles. I'm looking forward to the next lecture. Haha

I am a college student who has just started studying Spring. I watched lectures on other external sites and didn't know much about Spring DI containers, and I only used @Autowired. After watching this lecture, I was able to easily understand the core principles of Spring. Those who are new to Spring, please take this lecture... It really feels like grabbing you by the scruff of the neck and pulling you along. I will wait for the next Spring WebMVC lecture. Please release the lecture quickly!!

Hello. I am Andy Bae, a non-major who is studying to become a developer through government-funded education. I have reached a major turning point in my life, and I am learning a lot from your lectures. The weight of changing jobs and being a non-major was significant. I was really grateful for the practical lectures and detailed explanations you gave, and the delicate way you explained things you had done before. Sometimes, when I felt that the code was difficult, I was able to improve through repeated learning. I plan to continue to repeat learning in the future. Due to the limitations of government-funded education, I couldn't let it go like this, so I found your lectures and I think my life will change thanks to you. As a developer, I will work hard to become a competent developer with the goal of working at the same company as you. Thank you very much. I hope that the intermediate version of the core principles will come out soon. Thank you very much.

The neat lectures related to practical work are so good. The systematic and passionate lectures are incomparable to other lectures. Is there a plan to build a real website that can be used in the final stage of the lecture curriculum? (Not a site that imitates it) I think that while building a website, you will be able to learn necessary functions (e.g., mail sending function, security, common functions, etc.) in addition to the lectures, and the learners will also feel a sense of accomplishment. I am listening to another person's lecture on practical websites at Inflearn, but the lecture style is difficult, so I think it will be easier to understand if you do it in the instructor's style. I sincerely thank you for the great lecture.
