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.

Connecting microservices to a Netflix Eureka server

In this section, we will learn how to connect microservice instances to a Netflix Eureka server. We will learn both how microservices instances register themselves to the Eureka server during their startup and how clients can use the Eureka server to find microservice instances it wants to call.

To be able to register a microservice instance in the Eureka server, we need to do the following:

  1. Add a dependency to spring-cloud-starter-netflix-eureka-client in the build file, build.gradle:
implementation('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client')
  1. When running tests on a single microservice, we don't want to depend on having the Eureka server up and running. Therefore, we will disable the use of Netflix Eureka in all Spring Boot tests, that is, JUnit tests annotated...
