Building RESTful Web Services with Spring 5 - Second Edition

By: Raja CSP Raman, Ludovic Dewailly

Overview of this book

REST is an architectural style that tackles the challenges of building scalable web services. In today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs.The depth, breadth, and ease of use of Spring makes it one of the most attractive frameworks in the Java ecosystem. Marrying the two technologies is therefore a very natural choice.This book takes you through the design of RESTful web services and leverages the Spring Framework to implement these services. Starting from the basics of the philosophy behind REST, you'll go through the steps of designing and implementing an enterprise-grade RESTful web service. Taking a practical approach, each chapter provides code samples that you can apply to your own circumstances.This second edition brings forth the power of the latest Spring 5.0 release, working with MVC built-in as well as the front end framework. It then goes beyond the use of Spring to explores approaches to tackle resilience, security, and scalability concerns. Improve performance of your applications with the new HTTP 2.0 standards. You'll learn techniques to deal with security in Spring and discover how to implement unit and integration test strategies.Finally, the book ends by walking you through building a Java client for your RESTful web service, along with some scaling techniques using the new Spring Reactive libraries.

Developing RESTful web services

To create a new project, we can use a Maven command prompt or an online tool, such as Spring Initializr (, to generate the project base. This website comes in handy for creating a simple Spring Boot-based web project to start the ball rolling.

Creating a project base

Let's go to in our browser and configure our project by filling in the following parameters to create a project base:

  • Group: com.packtpub.restapp
  • Artifact: ticket-management
  • Search for dependencies: Web (full-stack web development with Tomcat and Spring MVC)

After configuring our project, it will look as shown in the following screenshot:

Now you can generate the project by clicking Generate Project. The project (ZIP file) should be downloaded to your system. Unzip the .zip file and you should see the files as shown in the following screenshot:

Copy the entire folder (ticket-management) and keep it in your desired location.
