Spring Integration : How to retrieve header values in Aggregator class -


how retrieve header values when combine 2 different messages using aggregator. have 2 messages different header same uuid. when combine these 2 messages using aggregator uuid, not find way retrieve header in custom aggregator class. mean header values lost? pls help.

the aggregated message gets union of headers. if there conflict, aggregator doesn't know value use header dropped, debug message...

logger.debug("excluding header '" + keytoremove + "' upon aggregation due conflict(s) "         + "in messagegroup correlation key: " + group.getgroupid());

if need retain values, need in different headers.
