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.

Embedded servers


One of the important concepts Spring Boot brings in is embedded servers.

Let's first understand the difference between traditional Java web application deployment and this new concept called embedded server.

Traditionally, with Java web applications, we build Web Application Archive (WAR) or Enterprise Application Archive (EAR) and deploy them into servers. Before we can deploy a WAR ;on the server, we need a web server or an application server installed on the server. The application server would be on top of the Java instance installed on the server. So, we need Java and an application (or web server) installed on the machine before we can deploy our application. The following figure shows an example installation in Linux:

Spring Boot brings in the concept of embedded servers, where the web server is part of the application deployable--JAR. To deploy applications using embedded servers, it is sufficient if ;Java is installed on the server. The following figure shows an example...
