Camel XML Example - CDI

Introduction

This example illustrates the use of Camel XML configuration files into Camel CDI applications.

While CDI favors a typesafe dependency injection mechanism, it may be useful to reuse existing Camel XML configuration files into a Camel CDI application. In other use cases, it might be handy to rely on the Camel XML DSL to configure its Camel context(s).

So that example demonstrates how to import a Camel XML configuration file and the level of interoperability between the Camel XML DSL and CDI.

It is implemented in Java with CDI dependency injection. It uses JBoss Weld as the minimal CDI container to run the application, though you can run the application in any CDI compliant container.

It is required to have the camel-core-xml dependency in the classpath when importing Camel XML configuration files using Camel CDI.

The camel-cdi and camel-stream components are used in this example. The camel-test-cdi module is used for the JUnit test runner.

Build

You can build this example using:

$ mvn package

Run

You can run this example using:

$ mvn camel:run

When the Camel application runs, you should see the following messages being logged to the console, e.g.:

Which pill (red|blue)?: 

You're being prompted which pill Neo should be taking. If he chooses the red one, Neo gets unplugged from the Matrix and the red pill serves as a location device to track his position into the farm to broadcast it and have the rebellion rescuing him, e.g.:
