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.

  • Choose Web as the dependency
  • Choose Kotlin as the language (second drop-down at the top of the screenshot)
  • Click on Generate Project and import the downloaded project into the eclipse as a Maven project

The following screenshot shows the structure of the generated project:

The following are some of the important things to note:

  • src/main/kotlin: This is the folder where all the Kotlin source code is present. This is similar to src/main/java in a Java project.
  • src/test/kotlin: This is the folder where all the Kotlin test code is present. This is similar to src/test/java in a Java project.
  • Resource folders are the same as a typical Java project--src/main/resources and src/test/resources.
  • Instead of JRE, Kotlin Runtime Library is used as the execution...
