Hands-On Cloud-Native Applications with Java and Quarkus

By: Francesco Marchioni

Overview of this book

Quarkus is a new Kubernetes-native framework that allows Java developers to combine the power of containers, microservices, and cloud-native to build reliable applications. The book is a development guide that will teach you how to build Java-native applications using Quarkus and GraalVM. We start by learning about the basic concepts of a cloud-native application and its advantages over standard enterprise applications. Then we will quickly move on to application development, by installing the tooling required to build our first application on Quarkus. Next, we’ll learn how to create a container-native image of our application and execute it in a Platform-as-a-Service environment such as Minishift. Later, we will build a complete real-world application that will use REST and the Contexts and Dependency injection stack with a web frontend. We will also learn how to add database persistence to our application using PostgreSQL. We will learn how to work with various APIs available to?Quarkus?such as Camel, Eclipse MicroProfile, and Spring DI. Towards the end, we will learn advanced development techniques such as securing applications, application configuration, and working with non-blocking programming models using Vert.x. By the end of this book, you will be proficient with all the components of Quarkus and develop-blazing fast applications leveraging modern technology infrastructure.

Developing Your First Application with Quarkus

In this chapter, we will be creating our first Quarkus application using the tooling that's available to us. As you will soon see, this is a pretty simple process that can be bootstrapped from the command line and doesn't require you to download any external tools. By using this process, we will be able to compile an application into a native executable and have solid evidence of how fast and thin a Java application can be when it's turned into native code by Quarkus.

In this chapter, we will cover the following topics:

  • Using the Quarkus Maven plugin to bootstrap our projects
  • Alternative methods to kick-start your projects (Quarkus CLI)
  • Creating and executing our first Quarkus application
  • Debugging the application from our IDE
  • Testing the application with an extension of the JUnit test framework
  • Turning our application...
