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 a RESTful service – the legacy approach


This example will review the traditional RESTful service development before jumping deep into Spring Boot.

STS will be used to develop this REST/JSON service.

Note

The full source code of this example is available as the legacyrest project in the code files of this book.

The following are the steps to develop the first RESTful service:

  1. Start STS and set a workspace of choice for this project.

  2. Navigate to File | New | Project.

  3. Select Spring Legacy Project as shown in the following screenshot and click on Next:

  4. Select Spring MVC Project as shown in the following diagram and click on Next:

  5. Select a top-level package name of choice. This example uses org.rvslab.chapter2.legacyrest as the top-level package.

  6. Then, click on Finish.

  7. This will create a project in the STS workspace with the name legacyrest.

    Before proceeding further, pom.xml needs editing.

  8. Change the Spring version to 4.2.6.RELEASE, as follows:

    <org.springframework-version>4.2.6.RELEASE&lt...
