---------------------------------------
Assignee: Andrea Cosentino
> LevelDB - Allow serializable objects in headers
> -----------------------------------------------
>
> Key: CAMEL-9584
> URL: https://issues.apache.org/jira/browse/CAMEL-9584
> Project: Camel
> Issue Type: Improvement
> Components: camel-core, camel-leveldb
> Affects Versions: 2.16.1
> Environment: all platforms (linux and windows)
> Reporter: Hubertus Willuhn
> Assignee: Andrea Cosentino
>
> I am using the LevelDB repository of Camel to store exchanges while
> aggregating.
> Every exchange contains a simple POJO in the header that serves as
> aggregation predicate.
> My POJO-class got the following signature:
> {{public class ID implements Cloneable, Serializable { ...}}
> and only 3 properties:
> {{private final String org;}}
> {{private final String type;}}
> {{private String key;}}
> But Camel don't want to serialize my class because:
> {{WARN org.apache.camel.impl.DefaultExchangeHolder -- Exchange in headers
> containing key: RECID with object: CEN-PRJ-22 of type: com.domain.ID is not
> valid header type, it will be excluded by the holder.}}
> I look into the "DefaultExchangeHolder" class and this function seems to be
> the problem:
> {{protected static Object getValidHeaderValue(String headerName, Object
> headerValue) { ...}}
> This function only allows default Java objects (like String).
> *But it should be possible to persist any "Serializable".*
> In the official documentation of LevelDB
> (http://camel.apache.org/leveldb.html) you can read:
> LevelDBAggregationRepository will only preserve any Serializable compatible
> data types. If a data type is not such a type its dropped and a WARN is
> logged. And it only persists the Message body and the Message headers. The
> Exchange properties are not persisted.
