By: Vivek Mishra, Héctor Veiga Ortiz

Overview of this book

Akka is an open source toolkit that simplifies the construction of distributed and concurrent applications on the JVM. This book will teach you how to develop reactive applications in Scala using the Akka framework. This book will show you how to build concurrent, scalable, and reactive applications in Akka. You will see how to create high performance applications, extend applications, build microservices with Lagom, and more. We will explore Akka's actor model and show you how to incorporate concurrency into your applications. The book puts a special emphasis on performance improvement and how to make an application available for users. We also make a special mention of message routing and construction. By the end of this book, you will be able to create a high-performing Scala application using the Akka framework.

XML support with Akka HTTP

As seen in the previous recipes, Akka HTTP has great integration for marshaling and unmarshaling. In the previous recipe, we saw how Akka HTTP can easily marshall and unmarshall JSON, thanks to Spray-json. The same is true with XML, thanks to Scala XML. Scala XML is a library that was initially part of the core Scala libraries but was later separated. Scala XML has an idiomatic API to write XML directly in your Scala code.

In this recipe, we will see how to easily integrate scala-xml dependency into our application to serialize and deserialize classes into and from XML.

Getting ready

To step through this recipe, we need to import the Hello-Akka project and the required Akka HTTP dependency we added in the previous recipe. Also, we will include the required scala-xml dependency.

How to do it...

For this recipe, perform the following steps:

  1. Get the required dependencies. 
  2. Edit the build.sbt file and add the akka-http-xml dependency as follows:
