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

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:
