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.

Deploying an Application to Cloud

Spring Boot has great support for most popular Cloud Platform as a Service (PaaS) providers.

Some of the popular ones are as follows:

  • Cloud Foundry

  • Heroku

  • OpenShift

  • Amazon Web Services (AWS)

In this section, we will focus on deploying our application to Cloud Foundry.

Cloud Foundry

The Cloud Foundry Java buildpack has excellent support for Spring Boot. We can deploy standalone applications based on JARs as well as the traditional Java EE WAR applications.

Cloud Foundry provides a Maven plugin to deploy applications:


Before we can deploy our application, we need to configure the application with a target and a space to deploy the application to.

The following are the steps involved:

  • We need to create...
