Use placeholders in camel expressions

[Anton Kirvel <An...@epam.com>]

Hi,
I tried to use jxpath expression like this one:
<camelContext>
 ...
 <choice>
   <when>

     <jxpath>/foo/@value > 1000</jxpath>

     ...

   </when>

    ...

 </choice>

 ...

</camelContext>


I'd like to make 1000 a configurable value. I use property file from spring context.

Is there any way to use spring property injection (like ${propery_name})  in camel expression?



Best Regards,
Anton Kirvel

Hi

A good place to check is the FAQ
http://camel.apache.org/faq.html

There is a known FAQ about this here:
http://camel.apache.org/how-do-i-use-spring-property-placeholder-with-camel-xml.html

In Camel 2.3 onwards there is support directly in Camel for that as
Spring cannot let 3rd party frameworks leverage their property
placeholder to the fullest.
