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.

Developer Tools


Spring Boot provides tools that can improve the experience of developing Spring Boot applications. One of these is Spring Boot developer tools.

To use Spring Boot developer tools, we need to include a dependency:

    <dependencies>
     <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-devtools</artifactId>
       <optional>true</optional>
     </dependency>
   </dependencies>

Spring Boot developer tools, by default, disables the caching of view templates and static files. This enables a developer to see the changes as soon as they make them.

Another important feature is the automatic restart when any file in the classpath changes. So, the application automatically restarts in the following scenarios:

  • When we make a change to a controller or a service class

  • When we make a change to the property file

The advantages of Spring Boot developer tools are as follows:

  • The developer does...
