Overview of this book

Spring 5.0 is due to arrive with a myriad of new and exciting features that will change the way we’ve used the framework so far. This book will show you this evolution—from solving the problems of testable applications to building distributed applications on the cloud. The book begins with an insight into the new features in Spring 5.0 and shows you how to build an application using Spring MVC. You will realize how application architectures have evolved from monoliths to those built around microservices. You will then get a thorough understanding of how to build and extend microservices using Spring Boot. You will also understand how to build and deploy Cloud-Native microservices with Spring Cloud. The advanced features of Spring Boot will be illustrated through powerful examples. We will be introduced to a JVM language that’s quickly gaining popularity - Kotlin. Also, we will discuss how to set up a Kotlin project in Eclipse. By the end of the book, you will be equipped with the knowledge and best practices required to develop microservices with the Spring Framework.

Preface

Centralized microservice configuration


Spring Cloud Config provides solutions to externalize the configuration of a microservice. Let's first understand the need to externalize microservice configuration.

Problem statement

In microservice architectures, we typically have a number of small microservices interacting with each other instead of a set of big monolithic applications. Each microservice is typically deployed in multiple environments--development, testing, load test, staging, and production. In addition, there can be multiple instances of microservices in different environments. For example, a specific microservice might be handling heavy load. There might be multiple production instances for that microservice in production.

The configuration of an application typically contains the following:

  • Database configuration: Details needed to connect to the database
  • Message broker configuration: Any configuration needed to connect to AMQP or similar resources
  • External services configuration: Other...
