Hello,
Perhaps I have misunderstood what aggregation can do - ideally
concatenate message bodies without using java code to concatenate messages
together. My goal is to concatenate lots of messages into a single message
e.g.
message 1 body --> 'aaa'
message 2 body --> 'aaa'
which results in a single message with body --> 'aaaaaa'
My spring DSL works in that 2 messages result in 1, but the message body is
not a concatenation but only a single message 'aaa'. Here is the Spring DSL:
<camelContext>
<route id="myroute" >
<from uri="activemq:queue:source" />
<aggregate batchSize="2" >
<correlationExpression>
<constant>true</constant>
</correlationExpression>
<to uri="activemq:queue:dest" />
</aggregate>
</route>
</camelContext>
I suspect that I need to write a custom aggregator bean (I have seen the
samples) to append the message bodies myself. Is this true ?
Regards,
Serge
