Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It integrates very well with the Java platform. Our Scala DSL implementation is built on top of the existing Java-based DSL, but it adds Scala syntax sugar to make building routes even more convenient.
To use the Scala DSL in your camel routes you need to add the a dependency on camel-scala which implements the Scala DSL.
