Spring Boot - Core Principles and Applications

I first got a job as a node.js developer and worked hard for a year at a black company, without being paid for up to 3 months, without any evenings or weekends. Eventually, I had health problems and had to take a break. At the crossroads of whether to go to a welding academy to learn welding skills or switch to a Java/Spring developer with a wider market, I thought it was really the last time and signed up for Younghan's Spring lecture and took it. During that process, I didn't have any money, so I studied for about 8 months while worrying about how many ramen I could eat a week, and now I've joined a decent mid-sized IT service company and it's been quite some time. Thanks to Younghan's lecture, I was able to build a solid foundation and I've grown into a recognized employee at the company and a trusted developer on the team. (Personally, I think the best thing is that I can live looking forward to the future rather than the present, lol) In each lecture, I was often impressed by the step-by-step order or documentation that beginners can't come up with without thinking deeply. Just as the current Younghannim lectures have been for me, I hope that you will continue to create lectures that can lend a helping hand to those who are lost and troubled like I was back then. Thank you!

As soon as the lecture was released, I bought it and watched all the lectures, even during the Samiljeol holiday. There were parts I already knew and parts I encountered new, and it was a fun time. When I watch general video lectures, they often show ~~ like this ~ without context or flow and end. In the past, (Hellfire Peninsula) was like this, but there was a process in the middle.. I experienced it myself and learned it, and now, as a better alternative, they show ~~ like this ~~, so I muttered to myself a lot while watching the lecture.ㅎㅎ That's right!! That's how it was ~ It used to be like that ㅎㅎㅎ (And come to think of it, I've been a developer for 13 years too... Ugh..) I think it would be good for many backend Spring developers to overcome their vague fears or difficulties about Spring Boot through this lecture. And I think their understanding of the technology they are using will increase. Many instructors are trying and releasing content that teaches how to use the framework, but I think this lecture is the only one that includes detailed content and practical content on the parts that should be utilized from a system operation perspective rather than a program perspective. If you look at recent job postings, the service operation experience ~ section is starting to be included as a required element, so I hope that those who are still juniors will gain indirect experience in responding to failures through this lecture. What I left from the long lecture was pinpoint pinpoint... It echoes. I'm going to install it. I hope you all have a happy and enjoyable developer life..... Thank you.

Finally, everyone is here. I really enjoyed the lectures of Kim Young-han, who I always trust and watch. The company I work for is SI, so I never did proper monitoring. I just fixed it when a client contacted me about a problem, and I never thought about introducing separate monitoring. However, while listening to this lecture, I was able to learn how important monitoring is and how easy it is to handle monitoring using Spring Boot. I'm going to apply this to my work. The stories in the "Next" chapter really resonate with me. I'm a 3rd-year SI backend junior developer who wants to move to a major service company, and I have a lot of concerns. I'm studying hard, but in practice, I repeat the development I've done (mainly CRUD), so there's nothing worth writing on my resume. Even if I wanted to write something on my resume, the only things I've worked on are "developed an admin page" and "created an automatic deployment script", so there's nothing to write. Even if I write down the improvements I made, I often wonder if they are really worth putting on my resume. At the same time, I also wonder if I am expecting too much from a junior developer who has only been working for 2 years and 3 months. If 2 years and 3 months had passed since I went to the Nekaraku Cup, would I have built a great career? When I think about these things, all I am left with is worries, and even if I study after work, all I get is worries. What level do you want from a 3rd-year backend developer? I am running like crazy because I don't want to fail at changing jobs, but since I don't know this, it feels like I am running through a tunnel with no exit. Of course, even if I know, I won't be able to see the exit right away, but I think the vague fear will go away.

I haven't heard everything yet, but it's definitely instructor Kim Young-han.. The lectures are so focused, and the lecture videos have become better than the ones from 3 years ago, where they only showed the room, and they've removed the background and only showed the instructor.. Thank you always.

I haven't listened to all the lectures yet, but I always really like Younghan's lectures because they always explain things from the beginning, whether it's Spring or JPA, in an easy-to-understand way. This was a chance for me, who only knew the concept that Boot would set things up for me, to learn exactly how to set things up and what inconveniences it solves! I really like how you explain things one by one in an easy-to-understand way! Please make more good lectures!

As soon as the Spring Boot lecture was released, I purchased it and watched the lecture, and there were parts that I had experienced in my field, and there were parts that I learned new this time. In particular, as I was developing and operating MSA for the first time in my field, I was curious about how to monitor and how other companies monitor, and this lecture had exactly the right content, so it was great. I don't have much experience, but I first encountered Younghan's lecture when I was a complete newbie with less than a year of experience, and while watching the lecture, I really wanted to improve my development skills and become a developer like Younghan, and I also wanted to work with developers like Younghan. So I tried hard to study development harder, and I'm still trying hard. ㅎㅎ As a result, I felt that I was getting closer to my goal, and although I've never actually met Younghan, I felt like he was my mentor, and I feel close to him and grateful every time I watch his lecture. I hope you always have good things! Haha If the next lecture comes out, I will buy a knife right away! Thank you.

Hello, From basic knowledge of HTTP web to Spring, JPA, and Spring Boot.. I really enjoyed watching it and am leaving my first review I enjoyed all the lectures, but I like the last part [Next] the most.. The part where you talk about what you want to say.. The parts you talk about in the lecture,, are really helpful and relatable to me ^^ It's been 4 years since I started working at SI, but until recently, I was wondering if I was on the right path But..! I got to know Younghan through Inflearn, and as I watched all of Younghan's videos, including lectures and YouTube, the path that used to be a question mark turned into an exclamation mark, and I feel like I'm finding the answer to the problem. I'm really happy, thank you.

When I started the introductory lecture, I wondered if I could finish the last roadmap, but I finally finished it! It was one of the most fun and enjoyable moments among all the lectures I've ever taken. I was so immersed in the lecture that I looked forward to listening to the instructor's Spring lecture during my daily work. Thank you so much for providing such a great lecture. I wonder if I would have been able to walk the path of a backend developer if it weren't for the instructor's Spring roadmap. When I was discharged from the military and in my third year of college, I was wondering what I should do among the developer positions and while experiencing each field, I came across the instructor's lecture. It was the first time in my life that I studied and created something this fun. Other fields weren't fun, but creating something with Spring Boot, connecting to a database, and querying it, the whole process was really fun. If it weren't for the instructor's well-organized Spring lecture, I don't think I would have walked this path. Thank you so much! This Spring Boot lecture was the most fun among the Spring roadmap lectures. It was the best lecture that was not boring at all, from Tomcat to Grafana. ㅎㅎ I was able to understand quickly because it explained the parts I was curious about easily. Above all, I think I was able to listen to it with interest because it was a lecture that made me think that I would encounter these things when I go to work. ㅎㅎ I also thought that it would be good if there were roadmaps or lectures on monitoring tools, logs, and test codes. I would really appreciate it if you could create such a roadmap after the Java roadmap and database roadmap that you are currently preparing. Recently, I am working on a toy project to learn while referring to Spring Data JPA and Spring lecture materials. As expected, when I tried the toy project, I was able to experience all the problems and errors that the instructor had mentioned. Haha. I believe that I will grow through this process of experiencing, fixing, and solving problems myself, so I am continuing to do it. Now that the Spring roadmap is over, I think this course is what I need the most. I will work harder to become a better backend developer with more growth. Thank you again for the great lecture. (I am waiting for the Java intermediate version..ㅎㅎ I want to listen to it soon!)
