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.

Externalised Configuration

Applications are typically built once (in JAR or WAR) and then deployed into multiple environments. The following figure shows some of the different environments an application can be deployed to:

In each of the preceding environments, an application typically has the following:

  • Connections to databases

  • Connections to multiple services

  • Specific environment configurations

It is a good practice to externalize configurations that change between different environments into a configuration file or database.

Spring Boot provides a flexible, standardized approach for externalized configuration.

In this section, we will look at the following:

  • How can properties from be used inside our services?

  • How do type-safe Configuration Properties make application configuration a cakewalk?

  • What kind of support does Spring Boot provide for Spring Profiles?

  • How can you configure properties in

In Spring Boot, is the default file...
