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, you'll be able to build modern, Internet-scale Java applications in no time. We would start off with the guidelines to implement responsive microservices at scale. We will then deep dive into Spring Boot, Spring Cloud, Docker, Mesos, and Marathon. Next you will understand how Spring Boot is used to deploy autonomous services, server-less by removing the need to have a heavy-weight application server. Later you will learn how to go further by deploying your microservices to Docker and manage it with Mesos. By the end of the book, you'll will gain more clarity on how to implement microservices using Spring Framework and use them in Internet-scale deployments through real-world examples.

Developing the Spring Boot microservice using Spring Initializr – the HATEOAS example

In the next example, Spring Initializr will be used to create a Spring Boot project. Spring Initializr is a drop-in replacement for the STS project wizard and provides a web UI to configure and generate a Spring Boot project. One of the advantages of Spring Initializr is that it can generate a project through the website that then can be imported into any IDE.

In this example, the concept of HATEOAS (short for Hypertext As The Engine Of Application State) for REST-based services and the HAL (Hypertext Application Language) browser will be examined.

HATEOAS is a REST service pattern in which navigation links are provided as part of the payload metadata. The client application determines the state and follows the transition URLs provided as part of the state. This methodology is particularly useful in responsive mobile and web applications in which the client downloads additional data based on user navigation...
