Hi,
I am aggregating contents of a csv file. the csv file can contain rows with
same e mail id. For those lines I need to generate a combined JSON with
contents aggregated.
I am using PreCompletionAwareAggregationStrategy and my aggregate method
looks like this.
if (oldExchange == null) {
return false;
}
// Code for matching e mail id goes here
//merges application data with old exchange
return oldExchange;
My route builder looks like this
from("direct:items")
.aggregate(header(FILE_NAME_ONLY), myAggregationStrategy)
.completionTimeout(500)
.to("direct:send-to-A");
>From the posts I came to know that we need to set an index to the
header, but not sure how it
works.
Every time my old exchange comes null so code after old exchange block
never gets executed.
Thanks,
Prasad
