| Scala DSL - Getting Started |
| =========================== |
| |
| Just like the Java DSL, the Scala DSL has a RouteBuilder |
| class (`org.apache.camel.scala.dsl.builder.RouteBuilder`) that you can |
| extend to implement your own routes. This example shows two very simple |
| routes: |
| |
| [source,java] |
| ---------------------------------------------------------- |
| class MyRouteBuilder extends RouteBuilder { |
| "direct:a" --> "mock:a" |
| "direct:b" to "mock:b" |
| } |
| ---------------------------------------------------------- |
| |
| INFO: From *Camel 2.15* onwards use |
| org.apache.camel.scala.dsl.builder.ScalaRouteBuilder and pass in the |
| CamelContext in the constructor, which will be used by the builder. The |
| old class RouteBuilder is deprecated. |
| |
| |
| If you compare this to the Java DSL, you notice: |
| |
| * there is no configure() method to override |
| * a route starts directly with a URI instead of `from(uri)` |
| * `→` is just an alias for `to` |
| |

| Setting the route ID |
| -------------------- |
| |
| To assign the unique ID to the Scala route, insert the `routeId` method |
| invocation after the "from" part of the DSL. |
| |
| [source,java] |
| ----------------------------------------- |
| "direct:a" routeId "route-b" to "mock:b" |
| ----------------------------------------- |

| Creating a new Camel Scala project |
| ---------------------------------- |
| |
| Camel offers Maven archetypes that |
| allow you to quickly setup a new project. |
| |
| To do this, you can execute the following Maven goal from the command |
| line (using Maven 3.0.3 or better): |
| |
| [source,java] |
| ---------------------- |
| mvn archetype:generate |
| ---------------------- |
| |
| This runs Maven interactively - just type `camel` and press <Enter> to |
| filter for Camel-related archetypes. + |
| From the list, pick the number for `camel-archetype-scala`, then fill |
| in the remaining details (such as the Camel version, _et cetera_). |
| |
| The generated project has a "readme" file with more instructions, and is |
| ready to compile and run from Maven using: |
| |
| [source,java] |
| --------------------- |
| mvn compile exec:java |
| --------------------- |
