Adding a varibale to the RouteDefination "from " in Apache camel

Question

I am looking to amend the RouteDefination from in Apache Camel

I hav eproperties file as below test1=test queue1=queue

code as below

from( "activemq:queue:{{test1}}.{{queue1}}")
.transform()
.simple(" ${body} {{test1}}.{{queue1}}.hello ${date:now:yyyyMMdd}")
.to("stream:out");

this will become for route as

from( "activemq:queue:test1.queue")

i am looking to make it as

from( "activemq:queue:test1.queue_20170606")

which is ${date:now:yyyyMMdd}

Answer 1

This is not possible in Camel - the from endpoint is static.

However ActiveMQ supports queue wildcards which you can use to consume from multiple queues, and you can use JMS message selectors.

• http://activemq.apache.org/wildcards.html
• http://activemq.apache.org/selectors.html

The latter is not so performant as it needs to do a query on the queue.

If you want to do a route per yyyyMMdd, then you need to add/remove routes dynamic in Camel. See other questions on SO how to do that.
