Just a bit of Apache Camel

Sometimes you write something and then you nearly forget that you did it … although it is quite handy sometimes, here are a few lines of Apache Camel XML running in Eclipse Kura:

I just wanted to publish some random data from Kura to Kapua, without the need to code, deploy or build anything. Camel came to the rescue:

<routes xmlns="http://camel.apache.org/schema/spring">
  <route id="route1">

    <from uri="timer:1"/>
    <setBody><simple>${bean:payloadFactory.create("value", ${random(100)})}</simple></setBody>
    <to uri="kura-cloud:myapp/topic"/>

  </route>
</routes>

Dropping this snippet into the default XML Camel router:

  • Registers a Kura application named myapp
  • Creates a random number between 0 and 100 every second
  • Converts this to the Kura Payload structure
  • And publishes it on the topic topic
