Overview of this book

Spring 5.0 is due to arrive with a myriad of new and exciting features that will change the way we’ve used the framework so far. This book will show you this evolution—from solving the problems of testable applications to building distributed applications on the cloud. The book begins with an insight into the new features in Spring 5.0 and shows you how to build an application using Spring MVC. You will realize how application architectures have evolved from monoliths to those built around microservices. You will then get a thorough understanding of how to build and extend microservices using Spring Boot. You will also understand how to build and deploy Cloud-Native microservices with Spring Cloud. The advanced features of Spring Boot will be illustrated through powerful examples. We will be introduced to a JVM language that’s quickly gaining popularity - Kotlin. Also, we will discuss how to set up a Kotlin project in Eclipse. By the end of the book, you will be equipped with the knowledge and best practices required to develop microservices with the Spring Framework.

  • Spring Boot does not implement any specific frameworks or specifications.

These questions still remain:

  • What is Spring Boot?
  • Why has it become so popular in the last couple of years?

To answer these questions, let's build a quick example. Let's consider an example application that you want to quickly prototype.

Building a quick prototype for a microservice

Let's say we want to build a microservice with Spring MVC and use JPA (with Hibernate as the implementation) to connect to the database.

Let's consider the steps in setting up such an application:

  1. Decide which versions of Spring MVC, JPA and Hibernate to use.
  2. Set up a Spring context to wire all the different layers...
