Using Property Placeholders for Any Kind of Attribute in the XML DSL in Camel

Solution Verified - Updated -


  • How to configure non-string attributes within the Camel XML DSL dynamically using property placeholders?
  • When you try to configure a non-string attribute like timeout dynamically (through property file) you may face error like not a valid integer value for timeout
  • Placeholders do not work for non-string values directly

  • We often use pollEnrich in our routes and we need to set different timeouts. At the moment, in blueprint route, we can only set timeout as an int value, directly:

<pollEnrich timeout="50000">

But we would like to be able to change this value dinamically from properties and then write something like:

<pollEnrich timeout="${pollEnrichTimeout}">
  • Here ${pollEnrichTimeout} is defined outside the route and we can adjust it as needed without the need to re-deploy the route.
  • Tried both ${} and { {} } placeholder but when Fuse try to deploy the route it fails and says that it is not a valid integer value for timeout.
