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.

Implementing security


It is important to secure the microservices. This will be more significant when there are many microservices communicating with each other. Each service needs to be secured, but at the same time, security shouldn't surface as an overhead. In this section, we will learn some basic measures to secure microservices.

Note

The full source code of this example is available as the chapter3.security project in the code files of this book under the following Git repository: https://github.com/rajeshrv/Spring5Microservice

Perform the following steps for building this example:

  • Create a new Spring Starter project, and select Web and Security (under core)
  • Name the project as chapter3.security
  • Copy rest endpoint from chapter3.bootrest

Securing a microservice with basic security

Adding basic authentication to Spring Boot is pretty simple. The pom.xml file will have the following dependency. This will include the necessary Spring security library files:
