It was a cost-effective lecture, and I learned a lot because the content was rich. There are many more expensive lectures that just teach you how to create APIs, but there are also many lectures on error handling, how to set up JWT tokens without security, etc., so I can't count them all, but I think it organized the content that people who are new to Spring want to know in a broad sense! Thank you. - It's great for creating boiler templates, but it's also very helpful for learning the basics of Spring ^^

It was very helpful that you explained in detail the essential and repetitive contents for carrying out a project based on SpringBoot, such as OAuth, authentication, authorization, jwt, global exception handling, swagger, etc. I was able to grow further by reading the book on creating a shopping mall written by the instructor of the course. Thank you.

I enjoyed the lecture. The content is good, but the quick feedback was a great help. It was a lecture uploaded last year, but I was able to quickly resolve the parts I was stuck on because you took care of it until now. It is a cost-effective lecture. If you are only familiar with the basics of Spring and Spring Boot and are starting a new project This is a lecture I would recommend before the project. If you only have basic Java concepts such as basic annotations, constructors, Enums, and interfaces, I think you will understand it as you listen to the explanation. I also had a hard time following the flow in the middle part, but since you explained it repeatedly, I felt like I had a better outline by the time I finished the lecture. I learned a lot other than the core Authorization, such as basic concepts of API and Postman utilization, and yml encryption/decryption using Jasypt. Through this lecture, I learned the basic concepts of social login authentication procedures, and I plan to implement a login system using OAuth2 based on the knowledge I learned. I was a bit worried because there was a lot of talk about the microphone and volume, but after listening to it, I realized that it was optional for me... I think people who are sensitive might feel a bit uncomfortable. Thank you for the great lecture.

I don't know if it's because I'm talking too much or if I'm stuttering, but I can't even tell what I'm saying because I'm talking before the class. I can't even concentrate.

Good content. Will work well for my project.
