Fixes#520Fixes#458 (for non-reactive binders)
Adds spring-cloud-stream-reactive module.
Introduces support for declarative @StreamListener and @Input and @Output annotated parameters.
Add StreamListenerArgumentAdapter and StreamListenerResultAdapter for wrapping bindable inputs
and outputs when passing arguments to declarative @StreamListener.
Adds support for using reactive types (Flux/Observable) with traditional binders.
Introduce FluxSender and ObservableSender for handling multiple streaming outputs per method.
Ensure that errors are caught and logged.
Fixing constructor assertions and Javadoc
Addressing PR comments
- rework @Input/@Output parameter validation
- renamed StreamListenerArgumentAdapter to StreamListenerParameterAdapter
- ensure that parameter direction is accounted for in the current adapters
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
Fixes#564
- Correct an issue where if the `cloud` profile is enabled but no Connectors are available,
no `ConnectionFactory` will be created;
- Introduce a property named `spring.cloud.stream.overrideCloudConnectors` that allows
to suppress the use of Cloud connectors in the application and fall back to Spring Boot
configuration. This is provided so that specific binders can be created with arbitrary
connectivity parameters if needed.
- Add documentation.
Fixes#557
Allow for a `defaultCandidate` flag on a binder configuration that, when FALSE,
ensures that the binder does not interfere with the default configuration process.
Fixes#542
- add option for `autoCommitOnError`
- make `autoCommitOnError` follow the state of `enableDlq` - no need to suppress commits if messages will be sent elsewhere
Honour the `SCS_KAFKA_TEST_EMBEDDED` flag when set as an environment variable
or Java property: when explicitly set to `false`, use an external broker and observe the
`SCS_EXTERNAL_SERVERS_REQUIRED` property (i.e. fail if server is missing). By default,
continue to run tests using an embedded broker.
