Send Message to a queue before start & end of a route starts prcoessing

[Felix Thomas <fe...@gmail.com>]

Hello,

    I have set a Timer componet pointing to a DB, which is triggered at
some interval.  I want to send a message to a queue with some value set in
the Header before the processing starts & after its ends .

Like

Message -    STARTED
Message - DATA1
Message - DATA2
Message -   END


I tried the below approach i don't see any message in the queue

  <route customId="false" id="routeMASTER1"
            xmlns="http://camel.apache.org/schema/spring">
            <from uri="timer://getData?period=2h" />
            <process ref="CustomHeaderProcessor" />
            <onCompletion mode="BeforeConsumer">
                  <setHeader headerName="TAG">
                    <constant>START</constant>
                  </setHeader>
                  <to
uri="rabbitmq://Localhost/MSEXCHANGE?autoDelete=false&amp;queue=MS&amp;username=XXXX&amp;password=XXX&amp;routingKey=DAMS"
                            id="to4" />
            </onCompletion>
            <onCompletion mode="AfterConsumer">
                  <setHeader headerName="TAG">
                    <constant>END</constant>
                  </setHeader>
                  <to
uri="rabbitmq://localhost/MSEXCHANGE?autoDelete=false&amp;queue=MS&amp;username=XXXX&amp;password=XXX&amp;routingKey=DAMS"
                            id="to5" />
            </onCompletion>
            <setBody id="setBody1">
                <constant>select * from TEST</constant>
            </setBody>
            <to uri="jdbc:DS?outputType=StreamList&amp;statement.maxRows=3"
id="to1" />

Re: Send Message to a queue before start & end of a route starts prcoessing

hello, 

Thanks for the tip.  I could make the logic work  using the split variables
since I was using Split .
CamelSplitIndex for start & CamelSplitComplete for the end.  Only problem
was that i had to disable threading or else it wont work properly always .

Cheers

BeforeConsumer means that the logic will be executed before the consumer
finishes, ie. when the route ends and before returning the response to the
caller if InOut and/or before executing the Exchange.done().

To capture the start of the route, you may want to look at interceptFrom.

Raúl.

sorry it works , but not the way i want it to be. 

the Start message comes in the end of the queue just before the end message
entry, ideally i thought it would be the first message in the queue , but
its the second last .  

any workarounds ?
