- Per-binding properties defined in `BindingProperties` need to hold the binder specific configurations needed when binding producer/consumers.
Previously, these were added in `ChannelBindingServiceProperties` as producer/consumer properties. Since these configuration properties are for
per-binding based on the input/output (consumer/producer) channel being bound it is better to move these properties into `BindingProperties`.
- Add some of the supported producer/consumer properties into BindingProperties
- This fixes#256
Rename CommonBinderProperties -> BinderPropertyKeys
Rename class AbstractBinderPropertiesAccessor.java -> AbstractBindingPropertiesAccessor.java
- instead of publishing to the default exchange, producers now publish to a topic exchange, to which the main queue is bound
- taps on a stream simply bind a queue to the same exchange with a name including the group for the tapping stream and a
routing key pattern `#`
- this means that multiple instances of the same tap stream will compete but multiple tap streams will get a copy
- for partitioned data, a single topic exchange is used, which each partition queue bound with its name as the routing key
- this means taps on partitioned data see the consolidated messages
Remove unused binder utilities.
Use TopicExchange Always
Use a TopicExchange when binding a pubSub producer for consistency.
Remove Deprecated Binder Method
Add group to BindingProperties
- also fix artifact name in test support pom
- also fix some kafka tests (does not imply that kafka taps work - yet)
Fixes GH-166 (https://github.com/spring-cloud/spring-cloud-stream/issues/166)
Since `onInit()` in the `MessageChannelBinderSupport` was called before the `evaluationContext` population,
the `RedisMessageChannelBinder#errorAdapter` caused `NPE` for its `evaluationContext`.
* Change the initialization order
* Use `ExpressionUtils` to populate `evaluationContext` - creates `StandardEvaluationContext` if there is no one in the `applicationContext`
* Add more initializations for the `RedisMessageChannelBinder#errorAdapter`
* Remove explicit `evaluationContext` population from the `AbstractTestBinder` to rely on the fix for this ticket
* Some other simple polishing
