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 our first Spring Boot microservice


In this section, we will demonstrate how to develop a Java-based REST/JSON Spring Boot service using STS.

Note

The full source code of this example is available as the chapter3.Bootrest project in the code files of this book under the following Git repository: https://github.com/rajeshrv/Spring5Microservice

  1. Open STS, right-click in Project Explorer window, select New Project, then select Spring Starter Project as shown in the following screenshot. Then click on Next:
  1. The Spring Starter Project is a basic template wizard, which provides a selection of a number of other starter libraries.
  2. Type the project name as chapter3.bootrest, or any other name of your choice. It is important to choose the packaging as Jar. In traditional web applications, a war file is created, and then deployed into a servlet container, whereas, Spring Boot packages all the dependencies into a self-contained, autonomous jar with an embedded HTTP listener.
