I am happy to announce that my new book, SpringBoot: Learn By Example, was published today on Leanpub.

What is SpringBoot?

Spring is one of the most popular Java frameworks out there for building web and enterprise applications.

Spring supports a variety of configuration approaches (XML, Annotations, JavaConfig, etc.), and properly configuring Spring applications can become a bit tedious and repetitive. To avoid these problems, the Spring team introduced Spring Boot to address the complexity of configuring a Spring application.

Spring Boot is an opinionated approach to configuring Spring-based applications. Spring Boot automatically configures the application components based on various criteria, like the jars you have on your classpath, the beans you have already configured, the properties configured, etc., which makes it very easy to get up and running quickly.

I strongly believe that the best way to learn or teach is by using examples. This book is filled with plenty of examples explaining the concepts in a step-by-step manner.

Who is this book for?

If you are looking for a fast-paced guide to learn how to build Spring-based applications using Spring Boot, this book is for you!

If you are a Spring developer but haven’t gotten your hands on Spring Boot and you feel like, “I know the drill, just tell me how to do it the Spring Boot way,” this book is what you are looking for!

If you are just starting to use Spring Boot and it is working great, but it all looks magical and you want to understand how Spring Boot works behind the scenes, this book will definitely be helpful to you!

If you are a seasoned Spring developer with a good grasp of Spring framework concepts and you just want a fast-paced guide to learn Spring Boot quickly, sure, this book is definitely for you!

I see a lot of people asking, “What is the difference between Spring MVC and Spring Boot?”, “Should I use Spring Boot or Spring MVC for my next web application?”, etc. See Here, Here, and Here. The short answer is, Spring Boot is nothing but Spring, but it helps you a lot to build Spring-based applications quickly. The next question would be, How?. The best way to explain it is by creating an application WITHOUT Spring Boot and showing how quickly you can develop the same application WITH Spring Boot.

This book explains how we normally build a Spring application without Spring Boot and shows how we can build the same application using Spring Boot in a much easier way so that you can correlate the concepts and see how Spring Boot increases developer productivity.

Spring Boot does so many things behind the scenes to automatically configure the application. This book explains how Spring Boot AutoConfiguration works behind the scenes in a very detailed manner and shows how we can create our own AutoConfiguration as well.
