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, you'll be able to build modern, Internet-scale Java applications in no time. We would start off with the guidelines to implement responsive microservices at scale. We will then deep dive into Spring Boot, Spring Cloud, Docker, Mesos, and Marathon. Next you will understand how Spring Boot is used to deploy autonomous services, server-less by removing the need to have a heavy-weight application server. Later you will learn how to go further by deploying your microservices to Docker and manage it with Mesos. By the end of the book, you'll will gain more clarity on how to implement microservices using Spring Framework and use them in Internet-scale deployments through real-world examples.

Developing the Spring Boot microservice using the CLI


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

  1. Install the Spring Boot command-line tool by downloading the spring-boot-cli-1.3.5.RELEASE-bin.zip file from http://repo.spring.io/release/org/springframework/boot/spring-boot-cli/1.3.5.RELEASE/spring-boot-cli-1.3.5.RELEASE-bin.zip.

  2. Unzip the file into a directory of your choice. Open a terminal window and change the terminal prompt to the bin folder.

    Ensure that the bin folder is added to the system path so that Spring Boot can be run from any location.

  3. Verify the installation with the following command. If successful, the Spring CLI version will be printed in the console:

    $spring –-version
    Spring CLI v1.3.5.RELEASE
    
  4. As the next step, a quick REST service will be developed in Groovy, which is supported out of the box in Spring Boot. To do so, copy and paste the following code using any editor...
