Apache Camel provides DSLs based on Java, Scala, Groovy, or XML. In this case, we’ll use Camel’s XML-based Spring DSL to specify the routing and configure our integration layer.

Note that as we are running inside Spring, it’s more practical to use the Spring XML version of the Camel DSL instead of the Java one, even though the latter is great for starting out.

Apache Camel 2.14 contains several new features and support for modern platforms. Its Java and Scala DSLs allow users to move away from XML and concentrate on core business logic.
