Hands-On Microservices with Spring Boot and Spring Cloud

By: Magnus Larsson

Overview of this book

Microservices architecture allows developers to build and maintain applications with ease, and enterprises are rapidly adopting it to build software using Spring Boot as their default framework. With this book, you’ll learn how to efficiently build and deploy microservices using Spring Boot. This microservices book will take you through tried and tested approaches to building distributed systems and implementing microservices architecture in your organization. Starting with a set of simple cooperating microservices developed using Spring Boot, you’ll learn how you can add functionalities such as persistence, make your microservices reactive, and describe their APIs using Swagger/OpenAPI. As you advance, you’ll understand how to add different services from Spring Cloud to your microservice system. The book also demonstrates how to deploy your microservices using Kubernetes and manage them with Istio for improved security and traffic management. Finally, you’ll explore centralized log management using the EFK stack and monitor microservices using Prometheus and Grafana. By the end of this book, you’ll be able to build microservices that are scalable and robust using Spring Boot and Spring Cloud.

Adding RESTful APIs

Now that we have projects set up for our microservices, let's add some RESTful APIs to our three core microservices!

The final result of this and the remaining topics in this chapter can be found in the $BOOK_HOME/Chapter03/2-basic-rest-services folder.

First, we will add two projects (api and util) that will contain code that is shared by the microservice projects, and then we will implement the RESTful APIs.

Adding an API and a util project

To add an API, we need to do the following:

  1. First, we will set up a separate Gradle project where we can place our API definitions. We will use Java interfaces in order to describe our RESTful APIs and model classes to describe the data that the API uses...
