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.

Putting it all together - Developing a customer registration microservice example


So far, the examples we have seen are not more than just a simple hello world. Putting our learnings together, this section demonstrates an end-to-end customer profile microservice implementation. The customer profile microservices will demonstrate the interaction between different microservices. It will also demonstrate microservices with business logic and primitive data stores.

In this example, two microservices--Customer Profile Service and Customer Notification Service-- will be developed:

As shown in the preceding diagram, the customer profile microservice exposes methods to create, read, update, and delete a customer, and a registration service for registering a customer. The registration process applies certain business logic, saves the customer profile, and sends a message to the customer notification microservice. The customer notification microservice accepts the message sent by the registration service...
