Preface

With growing demands, organizations are looking for systems that are robust and scalable. Therefore, the Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity.  Besides being flexible for Java development it also results in tedious configuration work. Spring Boot addresses the configuration difficulties of Spring and makes it easy to create standalone, production-grade Spring-based applications. It not only simplifies software development but also improves developer productivity. 

By focusing on developers, community, and customers, Spring Boot has alleviated untold hours of time normally spent plumbing infrastructure. It has also upset that apple cart and shown that we can, in fact, focus on building features our customers want on day one. 

Today almost one of every two Java developers, is using some part of the Spring portfolio. Spring Boot is solving problems for legions of customers, and this learning path can help you close the gap in your understanding.

Who this learning path is for

Java developers wanting to build production grade application using the newest and popular Spring tools for a rich end to end application development experience.

What this learning path covers

Section 1, Spring 5.0 By Example, will not only simplify software development but will also improve developers productivity. This section will cover effective ways to develop robust applications in Java using Spring.

Section 2, Learning Spring Boot 2.0-Second edition, provides a variety of features that address today’s business needs with a powerful database and state of the art MVC framework. This section will help you get up and running with all the latest features of Spring Boot.

Section 3, Spring Boot 2.0 Cookbook-Second edition, provides great flexibility for Java development, which also results in tedious configuration work. Spring Boot addresses the configuration difficulties of Spring and makes it easy to create stand-alone, production-grade Spring-based applications.This practical guide makes the existing development process more efficient. As developers, you will gain the skills and expertise to efficiently develop, test, deploy, and monitor applications using Spring Boot on premise and in the cloud. 

To get the most out of this learning path

1. The readers are expected to have a basic knowledge of Java including the latest features added by JDK 1.8 and  Java Developer Kit (JDK) 8 or higher
