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.

Running automated tests of the reactive microservice landscape

To be able to run tests of the reactive microservice landscape automatically instead of manually, the automated test-em-all.bash test script has been enhanced. The most important changes are as follows:

  • The script uses the new health endpoint to know when the microservice landscape is operational, as shown here:
waitForService curl http://$HOST:$PORT/actuator/health
  • The script has a new waitForMessageProcessing() function, which is called after the test data is set up. Its purpose is simply to wait for the creation of the test data to be completed by the asynchronous create services.

To use the test script to automatically run the tests with RabbitMQ and Kafka, perform the following steps:

  1. Run the tests using the default Docker Compose file, that is, with RabbitMQ without...
