dynamic property keys

[paramjyotsingh]

I am trying to read a property with dynamic property key

i have property like

1234_host=<hostname>
1234_port=<port>

where "1234" is group code, and it it dynamic, i will extract it from input file i receive and consume service running at this host

i have configuration like

<route>
  <from uri="file://inputfolder/" />
  <bean ref="extractGroupAndSetInHeader" />
  <setHeader headerName="groupHost">
        <constant>{{${in.header.groupID}_host}}</constant>
  </setHeader>
  <setHeader headerName="groupPort">
        <constant>{{${in.header.groupID}_port}}</constant>
  </setHeader>
  <recipientList>         
        <simple>cxfrs://http://${header.groupHost}:${header.groupPort}/item/${in.header.itemId}</simple>
  </recipientList>
</route>

But reading property with dynamic key does not works this way.

Can someone please help me about how to read properties with dynamic keys in camel spring DSL.

Thanks and Regards,
Paramjyot Singh

Can you try with simple instead of the constant
<simple>${properties:${header.groupID}_host}</simple>

Thanks Claus It works ...

[paramjyotsingh]

Hi Claus,

In different system I have camel 2.8.1, and i am getting error while executing same configuration on that version. Can you please tell me this does not work in camel 2.8.1.

[paramjyotsingh]

Hey Claus,

I looked at the documentation it says that nested expressions are not supported in 2.8.X and older. Can you please suggest any work around for this scenario.

Thanks and Regards,
Paramjyot Singh

You can use a java bean / processor, and then there is any API on
CamelContext to resolve property placeholders
http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/CamelContext.html#resolvePropertyPlaceholders(java.lang.String)

Then you can lookup the placeholders 2 times as nested are still not
supported. But then you can do this manually in some java code.

And then in the <setHeader> you can use a <bean> expression to call
your bean / processor.
