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 book goes beyond the use of Spring and explores approaches to tackle resilience, security, and scalability concerns. 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 for it.

I would like to thank my fiancée, Gaia, for helping me find the time to work on this book, and for dealing with my testiness after late-night writing sessions. I would also like to thank Neil Emerick from NightsBridge (http://www.nightsbridge.co.za) for providing me with the idea and concepts behind the sample RESTful web service that outlines this book.
Also, I would like to give gratitude to Chris Laffra and Michael Van Meekeren from the defunct Object Technology International, who gave me my first taste of commercial software development.
Finally, I wish to thank Nikhil Potdukhe and Menza Mathew from Packt Publishing for guiding me and helping me convert the original concept of this project into an actual book.

Preface
In today's connected world, APIs have taken a central role on the Web. They provide the fabric on which systems interact with each other. And REST has become synonymous with APIs. REpresentational State Transfer, or REST, is an architectural style that lends itself well to tackling the challenges of building scalable web services.
In the Java ecosystem, the Spring Framework is the application framework of choice. It provides a comprehensive programming and configuration model that takes away the "plumbing" of enterprise applications.
It will, therefore, come as no surprise that Spring provides an ideal framework for building RESTful web services. In this book, we will take a hands-on look at how to build an enterprise-grade RESTful web service with the Spring Framework. As an underlying theme, we will illustrate the concepts in each chapter with the implementation of a sample web service that deals with managing rooms in a hotel.
By the end of this book, readers will be equipped with the necessary techniques to create a RESTful web service and sufficient knowledge to scale and secure their web service to meet production readiness requirements.
What this book covers
Chapter 1, A Few Basics, discusses the REST architecture approach and its underlying principles.
Chapter 2, Let's Get Started, enables us to put the scaffolding together, before building a RESTful web service.
Chapter 3, Building RESTful Web Services with Maven and Gradle, looks at the building blocks of creating RESTful endpoints.
Chapter 4, Data Representation, discusses how to manage data representation before we proceed further with building more endpoints. This chapter also offers advice on creating common response formats and error handling.
Chapter 5, CRUD Operations in REST, expands on the previous chapters and takes a look at how you can map CRUD operations to RESTful endpoints.
Chapter 6, Performance, explains that for a web service to be production-ready, it needs to be performant. This chapter discusses performance optimization techniques.
Chapter 7, Dealing with Security, looks at how to ensure a web service is secure by delving into steps that designers need to take. This chapter looks at how to deal with authentication and authorization, as well as input validation techniques.
Chapter 8, Testing Restful Web Services, looks at how to guarantee that a web service delivers the expected functionality, and the testing strategies that designers need to consider. This chapter offers readers the approaches for creating comprehensive test plans.
Chapter 9, Building a REST Client, tells us how for a web service to be of any use, it must be consumed. This penultimate chapter focuses on how to build a client for RESTful web services.
Chapter 10, Scaling a Restful Web Service, explains that scalability is a vast topic and encompasses many aspects. In this last chapter, we discuss what API designers can put in place to help the scaling of their service.
What you need for this book
Readers will need the version 8 of the Java Development Kit (JDK) and Apache Maven to build the code samples in this book. In addition, readers who wish to delve into creating their own service, or simply look at the code samples in more detail, should equip themselves with their preferred IDE.
Who this book is for
This book is intended for those who want to learn to create RESTful web services with the Spring Framework. It goes beyond the use of Spring and explores approaches to tackling resilience, security, and scalability concerns that will prove useful to any service designer. To make the best use of the code samples included in this book, readers should have basic knowledge of the Java language. Any previous experience with the Spring Framework would also help in getting up and running quickly.
