Discover the RESTful technologies, including REST, JSON, XML, JAX-RS web services, SOAP, and more, for building today's Java-based microservices, big data applications, and web service applications using the Micronaut framework. This book is based on a course the Oracle-based author is teaching for UC Santa Cruz Silicon Valley which covers architecture, design best practices, and coding labs. This book gives you all the fundamentals from the top down: from the top (architecture) through the middle (design) to the bottom (coding). This third edition is updated with chapters on Micronaut JAX-RS and Micronaut Security, along with overall code updates to account for Micronaut 4. This book is a must have for any microservices or web services application programmer or developer building applications and services for today's enterprises. After reading and using this book, you'll be competent in using Micronaut and RESTful APIs for building today's microservices. Source code for the examples and case studies is provided.
