Spring: Microservices with Spring Boot

By: Ranga Rao Karanam

Overview of this book

Microservices helps in decomposing applications into small services and move away from a single monolithic artifact. It helps in building systems that are scalable, flexible, and high resilient. Spring Boot helps in building REST-oriented, production-grade microservices. This book is a quick learning guide on how to build, monitor, and deploy microservices with Spring Boot. You'll be first familiarized with Spring Boot before delving into building microservices. You will learn how to document your microservice with the help of Spring REST docs and Swagger documentation. You will then learn how to secure your microservice with Spring Security and OAuth2. You will deploy your app using a self-contained HTTP server and also learn to monitor a microservice with the help of Spring Boot actuator. This book is ideal for Java developers who knows the basics of Spring programming and want to build microservices with Spring Boot. This book is embedded with useful assessments that will help you revise the concepts you have learned in this book. This book is repurposed for this specific learning experience from material from Packt's Mastering Spring 5.0 by Ranga Rao Karanam.

Caching data from services plays a crucial role in improving the performance and scalability of applications. In this section, we will look at the implementation options that Spring Boot provides.

Spring provides a caching abstraction based on annotations. We will start with using Spring caching annotations. Later, we will introduce JSR-107 caching annotations and compare them with Spring abstractions.


Spring Boot provides a starter project for caching spring-boot-starter-cache. Adding this to an application brings in all the dependencies to enable JSR-107 and Spring caching annotations. The following code snippet shows the dependency details for spring-boot-starter-cache. Let's add this to our file pom.xml:


Enabling Caching

Before we can start using caching, we need to enable caching...
