Assignee: Brian McCallister
> Pluggable Stomp Message Mapping
> -------------------------------
>
> Key: AMQ-943
> URL: https://issues.apache.org/activemq/browse/AMQ-943
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Transport
> Affects Versions: 4.1
> Reporter: Dejan Bosanac
> Assigned To: Brian McCallister
> Fix For: 4.1
>
> Attachments: protocol-mapping.patch
>
>
> I have finally found time to finish this. Here's the draft version of the
> Pluggable Stomp Message Mapping implementation.
> Few notes:
> - New interface has been defined: ProtocolMapping (I wanted to use the same
> name as the message header that we check)
> - There are two implementations of this interface: DefaultProtocolMapping and
> ByteProtocolMapping
> - I used FactoryFinder to create appropriate mapper. The finder use the
> following path to find keys:
> META-INF/services/org/apache/activemq/transport/mapping/ (we can change this
> if you want)
> - The appropriate mapper is used according to the "protocol-mapping" header
> in the CONNECT message. For example protocol-mapping:byte for
> ByteProtocolMapping handler.
> - Currently I have implemented only the mapper for BytesMessage since I
> wasn't sure whether you want to integrate JSON mapper for MapMessages or
> distribute it in a separate library.
> - I have changed the test case that tests subscription for byte messages
> - This solution is not compatible with current mapping for byte messages. If
> you want backward compatibility, I can hard-code it in a ProtocolConverter
> class (as it was) since it could not be implemented through this mechanism.
> TODO:
> - test it more (create more unit test cases and test it more in a real
> environment)
> - create a proper documentation so others can create their handlers.
> - create a proper JavaDoc documentation for key interfaces and classes
> - create JSON mapper (integrated or external)
> - fix STOMP client(s)
> Give it a try and let me know your impressions
