Developing Spring and JPA based web applications

IntelliJ IDEA, Java basics, SQL basics, Spring MVC, Spring Boot, JPA, Spring Data JPA, Spring Security, QueryDsl, Git, GitHub, iTerm, DataGrip... When learning Java backend, I keep accumulating more things to learn than what I've learned. I'm not the only one... 🥺 I'm not the only one who feels this way... 🥺 I'm watching books or documentations of the relevant technologies (actually, almost all online lectures... 🤫) and Inflearn and YouTube lectures by Baek Gi-seon and Kim Young-han, and writing code and running them. 💭 I get to know 'Ah, there are things like this', but I only get to that point. The fastest way to learn something is 'imitation'. 👩🏻‍💻 Imitation is the mother of creation 😎 Through this lecture, I was able to put together the scattered puzzle pieces one by one, and when I saw them being applied in real life, functions and codes that I had only thought of or did not understand before began to appear little by little. 🔎 Also, he said, "You must know this!" and gave me facts... Although the fact that he was so harsh was really painful, it was good because I was able to figure out my current level and quickly figure out what I needed to study for my shortcomings. I think it's important to learn what's necessary to an appropriate degree in the vast technologies and information called backend. If you go through the lectures one by one while filling in what's lacking, you'll soon be like Baek Gi-seon 🎼 says, "If you've come this far, you should be able to do this yourself." Oh, by the way, if you look at the course reviews, there are some people who don't understand. It's not right to ask for a detailed explanation of the code since it's a real-life example lecture. There is nothing in the real world that is easily obtained without effort or compensation. This lecture clearly requires prior knowledge of the relevant technologies. I think you have designed the roadmap very well. This means that the target audience for this lecture is clearly defined. I still have a long way to go and there are many shortcomings, but thanks to Baek Gi-seon, I am moving faster on the right path without losing my direction. I am always grateful for the knowledge that you share at such a low cost. Then, I will see you in another lecture. Thank you so much 🙏🏻

Thank you for always giving great lectures. I am very satisfied with the content!!! However, if you lack basics, you may get hurt in the middle of the lecture. Be careful.

I feel like I'm getting 1:1 tutoring from the best developer ^^ The best!! I recommend it

I am a student who previously commented that it would be more fun if the lecture was given while creating a project, and I am so grateful that this type of lecture was created. I think I enjoyed it. Thank you.

I read a lot of Spring Boot and Spring Framework books, but I had a hard time applying them. But after completing the course, I realized that I thought the easy things were difficult... Or is it because the difficult things were explained in an easy way?? Anyway, the difficulty of Spring Boot dropped sharply. I regret why I studied so hard for something so trivial. Thank you for the great lecture.

I am leaving a review because I am so grateful to the teacher for the lecture. In fact, I was very worried about whether I could follow this lecture before taking it. Before starting the lecture, my learning level was Java, Spring, Spring Boot - I listened to the basic lecture once Thyemleaf, JPA, HTML, CSS, Javascript, Jquery, Git - I only got a taste of it Spring Security, Test writing method - I didn't even know what it was That was it, and I was able to create a very, very simple bulletin board using Boot, JPA, and Thymeleaf on my own. I am currently about 55% done, and I am very, very satisfied. This is how I am learning. In the lecture, from the beginning, the teacher explains what we will implement today and shows the process of writing the code directly, and uploads the commits at the beginning and end of the lecture. I created two project files, one for commit checkout and one for me to follow along. I followed all the codes in each lecture, and if there was an error or the version did not match, I checked it out from another project and compared it to implement the functions of the lecture and moved on. Although other reviews or even Mr. Kiseon himself said that the lecture was focused on practice and did not explain the theory in detail, I felt that he provided sufficient explanations for the minimum required to create a web project. Of course, he did not explain in detail what parameters are used in each method used in Spring Security, but I don't think that is necessary. You can realize it as you learn, and if you need it, you can look it up yourself. If you have learned the basics of technology and want to learn how those technologies are used to create a website, I highly recommend this lecture. I also have 45% of the lecture left, so I will try to follow along more diligently in the future. Thank you for creating such a great lecture.

It's sooooooooooo much fun! I'm currently learning about Spring Security by looking around because I'm not very good at the concepts. I have one team project experience, and I felt a lot of shortcomings while continuing to refactor on my own, so I decided to take the course. I'm at a level where I can use HTML and Thymeleaf without difficulty for the view, and I've been studying JPA for about 3 months using Yeonghan's book. (Almost finished) I was worried after reading the course reviews before purchasing the course, but I think I made the right decision to buy it. Even though it's only the beginning of the course, I'm so happy that I can directly and indirectly see and learn things like why you can get a repository from the controller side, the current transaction flow, view code writing, logical flow when writing test code, refactoring methods, and organizing methods that I haven't seen at my level. It's so great to focus on the course because it doesn't hesitate and just says the necessary things straight out. I want to try refactoring using jqpl or queryDsl to query the DB one last time and then dig into my personal project. (I got attacked a lot in interviews for relying too much on the spring data jpa function when using a new technology called JPA, so I thought I should have some experience writing SQL statements to query the DB ㅠ_) It's already been over 2 years? Thank you for giving such a good lecture. I think I'll learn a lot! (Annotation tuning is so hard ㅠㅠ. I feel like I have to study this deeply again)

I am listening because I want to know how to implement some functions in my project. The progress is still a bit slow, but as I watch, I think, 'I can introduce this function like this', 'Oh, this developer finds and fixes errors like this when an error occurs', and it also feels like we are working on a project together, so it is very immersive. At first, I was a little worried after reading the course reviews, but now I am listening without any regrets👍 Thank you for the great lecture!
