Fixes#519
Introduces some internal changes to the framework allowing the use
of other types than MessageChannel/SubscribableChannel as bindable
types (e.g. Flux, Observable, KStream, etc.)
- Modify BinderFactory to allow the retrieval and lookup of a
binder not only by name, but also by binding target type
- Subsequent changes to ChannelBindingService and tests to account
for the modified signature
- Introduce BindingTargetFactory as the contract for creating bound
elements
- Remove any references to chanels and bound elements and use
'binding target' systematically across the board
Reinstate our own Checkstyle checks with a reduced set of rules so that header
validation can be performed automatically at compile time.
Use ${project.version} for the checkstyle plugin configuration
Renaming some occurences of 'boundElement' to 'bindingTarget'
Renamed a stray occurence of 'channel'
Fix some occurences of String concatenation in the same line after reformatting
Fixes#505
The goals are twofold: to simplify the registration of new converters and
to add some consistency to the conversion process, and align them with the
way converters are used in generic Spring Messaging listeners, by describing
two possible transformations: inbound, message (including contentType)->targetClass,
and outbound payload+headers -> message. The idea is for the two
transformations to match the input and output directions of the bound channels.
List of changes:
- Create and configure input/output channels distinctly - reflected
in the definitions of `BindableChannelFactory` and `MessageChannelConfigurer`;
- Replace AbstractFromMessageConverter with bidirectional converters;
- Use the channel direction (input/output) to determine whether
`toMessage` or `fromMessage` will be invoked;
- Use contentType support from `AbstractMessageConverter` to map
converters to mime types instead;

Handle common aspects of message-channel binders:
- added generic, customizable ReceivingHandler and SendingHandler
- made doBindProducer delegate to a series of template methods
- made doBindConsumer delegate to a series of template methods
- moved partitioning to an interceptor, thus fixing #493
Removed unused manual ack handling
