19.4 Concluding the Book

This book covers an introduction to backend development based on Java.
In other words, this is an introduction to Spring Boot.
Spring Boot is the most popular framework for building web servers in Java.
I've been thinking a lot about how to convey the content in a fun, intuitive, and non-boring way.
I tried to get to the beginner's level as much as I had difficulty in the past.
Rather than explaining the concepts in detail, we focused on conveying the core concepts through hands-on creation.
I hope you can follow along with this book with a light heart, get a big picture of backend development, and experience the joy of development.

Recommended reviews

The explanations are detailed and friendly, making it easy to learn.
Essential concepts are explained using real-life examples, allowing for quick understanding, and solutions to errors that may be encountered during practice are also provided, allowing for smooth learning.
I had a goal of 'implementing CRUD on a bulletin board', and I was able to achieve it through this book.
_Pyo Su-yong

This book is designed to be easy to study on your own.
It's easy to follow along and understand the code as it has lots of comments and pictures, and the examples are also interesting.
It feels like it contains only the necessary information without being too excessive.
I've read several Spring Boot books, but this one was the easiest and most fun to learn from.
_Lee Ga-eun

I've always been interested in server development, but I had a lot of concerns about where to start and what to learn.
But through this book, I learned how servers work and how to develop servers.
I felt a sense of accomplishment as I created the project by inputting code one by one, and I gained confidence in my studies as I was able to fill in the areas where I had previously felt lacking.

_Park Joo-hyung

I learned Spring Boot while completing a six-month government-funded training course, but I ended up not even understanding the basic concepts.
Then, while studying with this book, I came to understand the concepts of web services and Spring Boot that I had not understood before.
In particular, I couldn't fully understand the MVC pattern even after watching YouTube and blogs, but I understood it right away with this book.
I feel like I can now create projects that I'm satisfied with.

_Choi Yu-jin

Many people want to learn Spring Boot, but it's difficult to actually get started.
This book explains in detail, with illustrations, everything from the basic concepts of Spring Boot to terminology and usage.
We also provide solutions to problems that may arise during the practice.
I recommend this book to anyone who is wondering how to get started with Spring Boot or is a beginner who is unfamiliar with the concepts and terminology.

_Lee Seong-hee

By following the code in the book, I was able to naturally learn backend development.
In addition, I was able to use and implement various functions such as HTML, CSS, JavaScript, DB, and Mustech grammar in addition to the basic functions of Spring Boot.
Although you will need to study more in-depth content, this book alone is enough to get started with Spring Boot.

_Choi Kyo-sun

I completed a 6-month Java + Spring course at the academy.
After working on a project in a short period of time, I had no idea what I was learning, but studying with this book gave me such a detailed and valuable learning experience that it made the lectures I had taken at the academy seem insignificant.
