Spring 5.0 Microservices - Second Edition

By: Rajesh R V

Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework’s core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring that focuses on Reactive Programming, you’ll be able to build modern, internet-scale Java applications in no time. The book starts off with guidelines to implement responsive microservices at scale. Next, you will understand how Spring Boot is used to deploy serverless autonomous services by removing the need to have a heavyweight application server. Later, you’ll learn how to go further by deploying your microservices to Docker and managing them with Mesos. By the end of the book, you will have gained more clarity on the implementation of microservices using Spring Framework and will be able to use them in internet-scale deployments through real-world examples.

Developing a Spring Boot microservice


The easiest way to develop and demonstrate Spring Boot's capabilities is by using the Spring Boot CLI, a command-line tool.

The following are the steps to set up and run Spring Boot CLI:

  1. Install the Spring Boot command-line tool by downloading the spring-boot-cli-2.0.0.BUILD-M1-bin.zip file from the following location URL:https://repo.spring.io/milestone/org/springframework/boot/spring-boot-cli/2.0.0.M1/
  1. Unzip the file into a directory of choice. Open a terminal window, and change the terminal prompt to the bin folder.

Note

Ensure that the /bin folder is added to the system path so that Spring Boot can be run from any location. Otherwise, execute from the bin folder by using the command ./spring.

  1. Verify the installation with the following command. If successful, the Spring CLI version will be printed on the console as shown:
      $spring –-version
      Spring CLI v2.0.0.M1
  1. As the next step, a quick REST service will be developed in groovy, which is supported...
