RESTful Java Web Services - Third Edition

By: Balachandar Bogunuva Mohanram, Jobinesh Purushothaman

Overview of this book

Representational State Transfer (REST) is a simple yet powerful software architecture style to create lightweight and scalable web services. The RESTful web services use HTTP as the transport protocol and can use any message formats, including XML, JSON(widely used), CSV, and many more, which makes it easily inter-operable across different languages and platforms. This successful book is currently in its 3rd edition and has been used by thousands of developers. It serves as an excellent guide for developing RESTful web services in Java. This book attempts to familiarize the reader with the concepts of REST. It is a pragmatic guide for designing and developing web services using Java APIs for real-life use cases following best practices and for learning to secure REST APIs using OAuth and JWT. Finally, you will learn the role of RESTful web services for future technological advances, be it cloud, IoT or social media. By the end of this book, you will be able to efficiently build robust, scalable, and secure RESTful web services using Java APIs.

Supporting custom request-response message formats

The JAX-RS framework uses entity provider components for the marshaling and unmarshaling of the message body content (entity) present in the response and request objects, respectively. It is the entity provider component that maps an entity with the associated Java types.

The following table lists the default entity mappings provided by the JAX-RS runtime via a set of built-in entity providers. When you use one of the internet media types present in the following table to represent the request or response entity body, the framework takes care of the conversion and reconversion of the entity body to the associated Java type:

Data types
