This book is composed of two menus: core concepts and advance concepts. The core concepts found in the recipes of chapters 1 to 3 are recommended to Java programmers who have no background in Spring Framework but are willing to start their career with the Spring 5 platform. Also, enthusiasts who know OOP and MVC concepts can also deal with the first three chapters since these are just the same ideas and principles being implemented in Spring 4 and below.

The recipes covered in chapters 4 to 13 are for experienced Spring developers who want to learn how to integrate modules such as Spring Security, Spring WebFlux, Reactor Core, Spring Batch, Spring Cloud, and advance related libraries. Aspects, advices, pointcuts, and interceptors, for instance, can only be understood by readers who know where in the Spring platform to apply the cross-cutting procedure. It also takes a deep knowledge of Spring when it comes to implementing REST web services and how to consume them using client APIs. Since this book is more inclined to asynchronous and reactive programming concepts, this book will be challenging for someone who knows Spring Framework very well.
