Overview of this book

The Spring framework has been the go-to framework for Java developers for quite some time. It enhances modularity, provides more readable code, and enables the developer to focus on developing the application while the underlying framework takes care of transaction APIs, remote APIs, JMX APIs, and JMS APIs. The upcoming version of the Spring Framework has a lot to offer, above and beyond the platform upgrade to Java 9, and this book will show you all you need to know to overcome common to advanced problems you might face. Each recipe will showcase some old and new issues and solutions, right from configuring Spring 5.0 container to testing its components. Most importantly, the book will highlight concurrent processes, asynchronous MVC and reactive programming using Reactor Core APIs. Aside from the core components, this book will also include integration of third-party technologies that are mostly needed in building enterprise applications. By the end of the book, the reader will not only be well versed with the essential concepts of Spring, but will also have mastered its latest features in a solution-oriented manner.

Preface

Building synchronous interprocess communication using AMQP


Another important feature of the design architecture in building microservices is studying and analyzing their behavior to each other when it comes to data exchange. Chapter 9, Spring Boot 2.0, established the conclusion that asynchronous, reactive, and blocking microservices work by exposing REST services that can be consumed by client applications. Although there is decoupling in the architectural design pattern, a microservice still has direct control over its clients because of the endpoint consumption occurring during the process. This gray area can still be considered to be tightly coupled behavior but to a minor degree. To implement a totally decoupled microservice, this recipe will introduce a new protocol that can initiate microservices to communicate synchronously with its clients without any endpoint intervention.
