When `listeners` are provided for `DefaultKafkaConsumerFactory`,
the target `KafkaConsumer` instance is proxied.
The `java.lang.reflect.Proxy` is `Serializable`,
but the value it is wrapping is not.
When the `MessageHeaders` is serialized (e.g. into persistent `MessageStore`),
it checks for `Serializable` type only on top-level object of the header.
Therefore, the `Proxy` is passing condition, but eventually we fail
with `NotSerializableException`, since the proxied object is not like that
* Remove `kafka_consumer` from a message before it reaches an aggregator
with its logic to serialize message into the store
This is a workaround until Spring for Apache Kafka is released
with the fix: https://github.com/spring-projects/spring-kafka/pull/2822
Fixes https://github.com/spring-cloud/stream-applications/issues/275
Many functions make use of `ComponentCustomizer` ot let end-user
to provide any custom configuration for target component used by the function.
First of all for use-case which are not covered by standard configuration
properties and secondly for those options which cannot be represented
as a configuration option.
* Add a sentence to READMEs of those functions which make use of `ComponentCustomizer`
with an expected generic argument type
* Add README into `rabbit-supplier` where it is fully missed at the moment
Add `JsonBytesToMap` function to allow conversion between byte[] and JSON Map.
Fixes https://github.com/spring-cloud/stream-applications/issues/441
* Introduce a `JsonBytesToMap` as a part of a `payload-converter-function` module
which is auto-discovered by Spring Cloud Function scanning algorithm - the `functions` package.
* Add a `payload-converter-function` as dependency into an `aggregator-function`
* Compose `jsonBytesToMap|aggregatorFunction` for the `aggregator-processor`
* Verify a `JsonBytesToMap` function in action with an `AggregatorProcessorTests`
* Mentioned such a payload conversion in the `aggregator-processor` README
Fixes https://github.com/spring-cloud/stream-applications/issues/373
The fix in Spring Integration has made it into the latest SNAPSHOT.
See more info in the linked issue
* Update to the latest Testcontainers: it does not require credential for pull command any more
* Remove obsolete `MessageStoreType.GEMFIRE`
* Add `<doclint>syntax</doclint>` to ignore missed javadocs on public methods
Spring Boot `@AutoConfiguration` comes now with a `proxyBeanMethods = false`,
so we cannot call bean methods within the same configuration class.
* Rework `HeaderEnricherFunctionConfiguration` for bean methods autowiring
* Create an `ExpressionEvaluatingHeaderValueMessageProcessor` instances directly
in the `headerEnricher` bean definition and propagate an injected `BeanFactory`
* Re-enable disabled tests
Fixes#369
