Overview of this book

GSON is a specialized Java-based library for handling JSON data, developed by Google. GSON demonstrates an efficient use of CPU time, memory efficiency, the library, and developer productivity. This book will help you implement GSON in your Java project. Instant GSON is a practical, hands-on guide that provides you with all the implementation features of the GSON API through coded examples, which will help you take advantage of the real power that is behind the GSON API, and give you a good grounding to use it in your projects. Instant GSON starts with an introduction to the JSON data format and GSON library. It will take you through the configuration steps required to set up a GSON-based Java project. You will learn about the top features of the GSON library, which includes handling generic type and nested class objects in Java, implementing versioning support, exclusion strategies, and pretty printing. At the end of the book you will find some useful references to articles, blogs, and active communities.

Chapter 1. Instant GSON

Welcome to Instant GSON. This book has been especially created to provide you with all the information that you need to get started with GSON. You will learn the basics of GSON, get started with building JSON representation, and discover some tips and tricks for coding GSON.

This book contains the following sections:

So, what is GSON? helps you find out what GSON actually is, what you can do with it, and why it's so great.

Configuring GSON in Eclipse will help you configure the GSON library in Eclipse IDE for a simple Java project and a Maven type Project.

Quick start – creating your first JSON in GSON will show you how to perform one of the core tasks of GSON: creating courses. Follow the examples discussed in this section to get started with GSON, which will be the common code of most of the GSON use.

Top 12 features you need to know about helps you learn how to perform handling generic-typed, custom serialization and field exclusion strategy. By the end of this section you will be able to:

  • Convert a Java object to JSON

  • Serialize and deserialize in GSON

  • Use the GSON nested classes handling mechanism

  • Convert a Java array to a JSON array

  • Handle generic-type classes while working with GSON serialization and deserialization

  • Handle a null object while working with GSON

  • Use versioning support in GSON

  • Use the no argument constructor support

  • Create a custom field name from a Java object to JSON output string

  • Exclude a JSON field while serializing it in GSON

People and places you should get to know provides you with many useful links to the project page and forums, as well as a number of helpful articles, tutorials, blogs, and Twitter feeds by the GSON super-contributors, as every open source project is centered around a community.
