Chris Pimlott updated CAMEL-8246:
---------------------------------
Summary: ZipAggregationStrategy does not preserve headers (was:
ZipAggregationStrategy)
> ZipAggregationStrategy does not preserve headers
> ------------------------------------------------
>
> Key: CAMEL-8246
> URL: https://issues.apache.org/jira/browse/CAMEL-8246
> Project: Camel
> Issue Type: Bug
> Affects Versions: 2.14.0
> Reporter: Chris Pimlott
> Labels: aggregate, zip
>
> ZipAggregationStrategy does not preserve any headers from the aggregated
> exchanges. This makes it difficult to do something like name the output zip
> file based on the correlation key:
> {code:xml}
> <from uri="direct:input"/>
> <aggregate strategyRef="zipStrategy" eagerCheckCompletion="true">
> <correlationExpression>
> <simple>${header[batchId]}</simple>
> </correlationExpression>
> <completionSize>
> <simple>${header[batchSize]}</simple>
> </completionSize>
> <setHeader headerName="CamelFileName">
> <simple>batch-${header[batchId]}.zip</simple>
> </setHeader>
> <to uri="direct:output"/>
> </aggregate>
> {code}
> This behavior is inconsistent with other existing AggregationStrategies,
> including AggregationStrategyBeanAdapter, FlexibleAggregationStrategy,
> UseLatestAggregationStrategy, and UseOriginalAggregationStrategy, which all
> use the first exchange received (or a copy of it) to initialize the
> aggregated exchange, hence preserving headers and properties, including those
> which may used to determine the correlation of related exchanges.
