Spring 5.0 Microservices - Second Edition

By: Rajesh R V

Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework’s core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring that focuses on Reactive Programming, you’ll be able to build modern, internet-scale Java applications in no time. The book starts off with guidelines to implement responsive microservices at scale. Next, you will understand how Spring Boot is used to deploy serverless autonomous services by removing the need to have a heavyweight application server. Later, you’ll learn how to go further by deploying your microservices to Docker and managing them with Mesos. By the end of the book, you will have gained more clarity on the implementation of microservices using Spring Framework and will be able to use them in internet-scale deployments through real-world examples.

Spring Boot for building RESTful microservices


Spring Boot is a utility framework from the Spring team for bootstrapping Spring-based applications and microservices quickly and easily. The framework uses an opinionated approach over configurations for decision making, thereby reducing the effort required on writing a lot of boilerplate code and configurations. Using the 80-20 principle, developers should be able to kick start a variety of Spring applications with many default values. Spring Boot further presents opportunities to the developers for customizing applications by overriding auto-configured values.

Spring Boot not only increases the speed of development, but also provides a set of production-ready ops features such as health checks and metrics collections. Since Spring Boot masks many configuration parameters and abstracts many lower level implementations, it minimizes the chances of errors to a certain extent. Spring Boot recognizes the nature of the application based on the libraries...
