Spring Boot Primer (Second Edition)

■An introduction to Spring Boot so you won't regret it
If you have this book in your hands, you may have plans to develop with Spring(Spring Boot) in the future.

Everyone feels anxiety and fear when trying something for the first time. (At the same time, you may feel excited). But that's a good thing. Because we strive to drown out the anxiety.

Whatever the reason, trying new things leads to growth. The more unknown it is, the greater the degree of growth. Therefore, for you who have taken that step, growth is waiting for you.

When I started learning about Spring, I bought a number of Spring-related books (because I was afraid). But I didn't have a satisfying book. With the intention of changing that situation, we published the first edition of this book in 2018. Since Spring is also evolving, I have published the second edition.

In this book, you will use Spring to create one web application. Start by learning from the basics of Spring and gradually complete your application. By doing this, you will be able to acquire not only Spring but also the knowledge necessary for web development.

In other words, you can level up from knowing nothing about web development to being able to master Spring at once.

However, this book emphasizes practice rather than theory. There are various learning methods, but actually experiencing it is one of the efficient ways to learn. This is because it is scientifically known that the output has a high retention rate of knowledge. Also, when you actually make it and execute it, your anxiety and fear will disappear, so you will gain confidence.

It is better to actually move your hands to make it, but at first it is okay to just read a book. Since all the sample code can be downloaded, you can create an application even from the middle.
