This book is for both novice developers in general and experienced Spring developers. It will teach you how to override Spring Boot's opinions and frees you from the need to define complicated configurations.

An entry-level book for Spring Boot; although the book has a lot of examples, somehow I feel that most of them are overly simplistic and that going through the basic Boot examples both via tutorials or the reference documentation would have been a better use of my time.
Very nice book for all those people who want to learn something about Spring boot.
Of course is not a book for people who don't know java and spring. You should have some knowledge about fundamentals of Spring Framework.
What you will know after reading?
How to setup, configure and run spring boot. It is obvious ;) But in my opinion way how author presents that is very good. It simple, logical and cover most of common cases (and wrote some words about exceptional cases). You can treat as a "manual by example".
Finally I found some small mistakes and inconsistency in examples but as I wrote at beginning you should know about spring and then you can easily recognize this issues.
Java chapter needs a version of spring-social-github which is not directly available : I had to download the source code and build it locally to make it work.
I really miss some section about Spring Batch, but overall, liked it.
Unfortunately, reading this book is not any better than reading the official Spring Boot documentation. It's a good, but justifiably unnecessary introduction to the awesome technology.
Overall a good read and includes some useful tips and tricks. The book would have been better if it contained a more complete examples and some unit tests.
