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.

Representational State Transfer (REST) is basically an architectural style for the web. REST specifies a set of constraints. These constraints ensure that clients (service consumers and browsers) can interact with servers in flexible ways.

Let's first understand some common terminologies:

  • Server: Service provider. Exposes services which can be consumed by clients.
  • Client: Service consumer. Could be a browser or another system.
  • Resource: Any information can be a resource: a person, an image, a video, or a product you want to sell.
  • Representation: A specific way a resource can be represented. For example, the product resource can be represented using JSON, XML, or HTML. Different clients might request different representations of the resource.

Some of the important REST constraints are listed as follows:

  • Client-Server: There should be a server (service provider) and a client (service consumer). This enables loose coupling and independent evolution of the server and client as new technologies...
