Spring: Microservices with Spring Boot

By: Ranga Rao Karanam

Overview of this book

Microservices helps in decomposing applications into small services and move away from a single monolithic artifact. It helps in building systems that are scalable, flexible, and high resilient. Spring Boot helps in building REST-oriented, production-grade microservices. This book is a quick learning guide on how to build, monitor, and deploy microservices with Spring Boot. You'll be first familiarized with Spring Boot before delving into building microservices. You will learn how to document your microservice with the help of Spring REST docs and Swagger documentation. You will then learn how to secure your microservice with Spring Security and OAuth2. You will deploy your app using a self-contained HTTP server and also learn to monitor a microservice with the help of Spring Boot actuator. This book is ideal for Java developers who knows the basics of Spring programming and want to build microservices with Spring Boot. This book is embedded with useful assessments that will help you revise the concepts you have learned in this book. This book is repurposed for this specific learning experience from material from Packt's Mastering Spring 5.0 by Ranga Rao Karanam.

HATEOAS (Hypermedia as the Engine of Application State) is one of the constraints of the REST application architecture.

Let's consider a situation where a service consumer is consuming numerous services from a service provider. The easiest way to develop this kind of system is to have the service consumer store the individual resource URIs of every resource they need from the service provider. However, this would create tight coupling between the service provider and the service consumer. Whenever any of the resource URIs change on the service provider, the service consumer needs to be updated.

Consider a; typical web application. Let's say I navigate to my bank account details page. Almost all banking websites would show links to all the transactions that are possible on my bank account on the screen so that I can easily navigate using the link.

What if we can bring a; similar concept to RESTful services so that a service returns not only the data about the requested resource, but...
