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.

Trying out the Swagger documentation

To browse the Swagger documentation, we will use the embedded Swagger viewer. If we open the http://localhost:8080/swagger-ui.html URL in a web browser, we will see a web page that looks something like the following screenshot:

Here, we can find the following:

  • The general information we specified in the SpringFox Docket bean and a link to the actual Swagger document, http://localhost:8080/v2/api-docs
  • A list of API resources; in our case, the product-composite-service API
  • At the bottom of the page, there is a section where we can inspect the models that are used in the API

This is how it works:

  1. Click on the product-composite-service API resource to expand it. You will get a list of operations that are available on the resource.
  2. You will only see one operation, /product-composite/{productId}. Click on...
