* Refinement for gateway Mono processing
* Introduce a `MessagingGatewaySupport.MonoReplyChannel` instead of
`FutureReplyChannel` for better on demand handling and reusing a
`Mono` returned from the target handler
* Refactor `GatewayProxyFactoryBean` to identify a target return type
(including generics for `Function`) during initialization
* Handle a `Mono` return type via
`MessagingGatewaySupport.sendAndReceiveMessageReactive()`
* Some `@Nullable` in the `GatewayProxyFactoryBean` and `ExpressionUtils`
* Add `MonoFunction` test-case into the `FunctionsTests.kt`
* * Deprecate `GatewayProxyFactoryBean.setServiceInterface()` in favor of
ctor initialization
* Fix `GatewayProxyFactoryBean.setServiceInterface()` usage in tests
The method reference together with a `IntegrationFlows.frm(Supplier<?>)`
do the trick to avoid a method name resolution and also gives us a code
navigation in the IDE
* Improve `channel.adoc`: polishing, new channels, java config
* Make `LoadBalancingStrategy` in the `DirectChannel` ctor as
`@Nullable` to reflect the real logic behind
* More Dos and polishing according PR comments
* Mention WebFlux and RSocket endpoints in the `endpoint-summary.adoc`
table
* More reactive streams docs
* `SourcePollingChannelAdapter` polishing
* Wrap multi-value publisher into `Mono.just()` in the `AbstractMessageProducingHandler`
instead of emitting just only a first item for the standard reply
Doc polishing
* Hide `toReactivePublisher()` from lambdas
When an `IntegrationFlow` is declared via lambda, it is impossible
to materialize it as a `Publisher` since we lose a Lambda context and
finish with a `NoSuchBeanException` when we would like to inject that
`Publisher`
* Make `IntegrationFlowDefinition.toReactivePublisher()` as `protected`
and expose it on the `IntegrationFlowBuilder` level
* Use `Channels` as a singleton: no reason in overhead for its instances
* Some code style polishing for `IntegrationFlowDefinition`
* Restore `Channels.super()` call
* Fix some typos in `webflux.adoc` and `dsl.adoc`
* Make `FunctionsTests.kt` more Kotlin friendly
* Improve RSocket components and tests for them,
especially rely on the default `RSocketStrategies` in the
target SF RSocket components
* Rework `ServerRSocketConnector.setClientRSocketKeyStrategy` to use the whole `MessageHeaders` for consultation.
It turns out that just destination is not enough since it can be used from different clients
* Make the key based on the provided `setupData` by default
* Include all the `MessageHeaders` into the `RSocketConnectedEvent`
* Improve Docs according review feedback and Docs in SF
Doc polishing
Fixes https://github.com/spring-projects/spring-integration/issues/3052
Starting with version `5.1`, a `LambdaMessageProcessor` is based on the
`MessageConverter` instead of plain `ConversionService`.
(A `ConfigurableCompositeMessageConverter` is used from the application
context.)
However a type conversion based on the `@IntegrationConverter` is lost
in the `GenericMessageConverter` because it doesn't use an
`integrationConversionService` from the application context
* Change `ConfigurableCompositeMessageConverter` to configure a
`GenericMessageConverter` with an `integrationConversionService`
if any
* Fix `MessagingMethodInvokerHelper` to populate a `BeanFactory` into
its internal `ConfigurableCompositeMessageConverter`
* Ensure in the `LambdaMessageProcessorTests` that
`@IntegrationConverter` is applied for ``LambdaMessageProcessor` as well
**Cherry-pick to 5.1.x**
Fixes https://github.com/spring-projects/spring-integration/issues/3047
* Improve `GatewayProxyFactoryBean` to determine the return type of the
method call from the interface generic types, when the `serviceInterface`
is a `java.util.function.Function`
* Propagate `MethodArgsHolder` as a `rootObject` for SpEL evaluations
* Deprecate `#gatewayMethod` and `#args` evaluation context variables
in favor of `MethodArgsHolder` as root object.
They will be removed in the future release and a single
`EvaluationContext` will be used for all the gateway expressions
* Introduce an
`IntegrationFlows.from(Class<?> serviceInterface, Consumer<GatewayProxySpec> endpointConfigurer)`
to allow to configure any valid gateway proxy options similar to what
we have with the `<gateway>` and `@MessagingGateway`.
This way we are very close to consistency between different approaches
* * Remove `default` prefix from `GatewayProxySpec` options
* Document the change
- republish certain events as `ApplicationEvent`s.
* * Add ApacheMinaFtplet to provide the same functionality with FTP
* Fix typo
* * Polishing javadocs and event toString() methods

Statically defined flows with a publish/subscribe channel invoke the
subscriptions in natural (declared) order.
The components in the flow are started by the application context in
phases (consumers, then producers) and bean declaration order within
each phase.
When a dynamically declared flow is started, the components are started
by the `StandardIntegrationFlow` in reverse order (last to first) so that
we don't start producing messages before the flow is fully wired.
This has the side-effect that pub/sub subscribers are invoked in an
unnatural (last to first) order.
All subscription sub-flows start with a bridge from the pub/sub channel
to the first component's input channel.
The `BroadcastingDispatcher` honors the `Ordered` interface.
Change the `PublishSubscribeSpec` to set the `order` property so that
subscribers are always invoked in the natural order, regardless of whether
the flow is statically or dynamically defined.

* Refactor more `MessageHandlingException`s to include `this` into an
exception message
* Revert using `MessagingException` in some places which really are not
about messaging.
This helps to wrap them into `MessageHandlingException` later in the
`MessageHandler` for the `BeanDefinition` reference
* Remove `volatile` from configuration properties in the affected
classes
* Remove already deprecated `JmsOutboundGateway.setPriority()`
* Add `resource` and `source` for `BeanDefinition` in the
`AbstractChannelAdapterParser` & `AbstractInboundGatewayParser`
* Document the feature
* `exclude group: 'org.springframework'` from all non-core Spring
dependencies to avoid CLASSPATH conflicts
* Remove suppress from from some modules which don't report compilation
warnings any more
* Fix deprecation warnings reported after upgrades
* GH-2988: Use `@Config(proxyBeanMethods=false)`
Fixes https://github.com/spring-projects/spring-integration/issues/2988
For faster startup (and possibility to compile to native code with GraalVM)
use a `proxyBeanMethods = false` on all the `@Configuration` classes
in the Framework
* Provide some other code style polishing
* * Fix Checkstyle violation
Fixes https://github.com/spring-projects/spring-integration/issues/2987
To resolve XSD files properly from the classpath, their HTTPS reference
must be present in the `spring.schemas` to avoid the Internet interaction
for resolving an XSD file
**Cherry-pick to 5.1.x, 5.0.x & 4.3.x**
* GH-2748: Add bean definition info into exceptions
Fixes https://github.com/spring-projects/spring-integration/issues/2748
In many cases Spring Integration stack traces doesn't contain any
relations to end-user code.
Just because a target project code mostly contains only a configuration
for out-of-the-box components without any custom code.
When exception is thrown from such an out-of-the-box component, it is
hard from the stack trace to determine a configuration source for those
components.
* Add a logic into the `IntegrationObjectSupport` to obtain a its own
`BeanDefinition` from the `BeanFactory` to include a `resource` and
`source` (if any) into the `toString()` representation, as well as add
a new `getBeanDescription()` to get such an info at runtime
* The `toString()` is simply used by `this` reference in the message
for `MessagingException` thrown from the `IntegrationObjectSupport`
implementations
* Modify an exception message for the `MessageTransformingHandler` and
`MessageFilter` to make it based on `this`.
The `AbstractMessageHandler` already includes `this` into its exception
message
* Modify a `AbstractConsumerEndpointParser` and
`AbstractAmqpInboundAdapterParser` (as a sample) to include a `resource`
and `source` into a `MessageHandler` `BeanDefinition`.
* Include an `IntegrationFlow` `BeanDefinition` `resource`
(`@Configuration` class) and its bean method as a `source` into all
child beans declared during flow parsing in the `IntegrationFlowBeanPostProcessor`
* Add `IntegrationFlowRegistrationBuilder.setSource()` for manually
registered flows: there is no configuration parsing phase to extract
such an info from `BeanFactory`
* Propagate that `source` into all the child beans provided by the
`IntegrationFlow`
* Modify a `LambdaMessageProcessor` exception message to include a
method info in case of `InvocationTargetException`
* Do not cast explicitly for `ConfigurableListableBeanFactory` in the
`IntegrationObjectSupport` to avoid tests modifications for mocking
directly into `ConfigurableListableBeanFactory`.
Use `instanceof` instead in the `getBeanDescription()`
* * Fix Checkstyle issues
* * Fix `IntegrationGraphServer` and `IntegrationMBeanExporter`
to rely on the `NamedComponent` for channel names instead of
always call `toString()` which is now much more than just a bean name
* Don't describe a `componentName` if it is the same as a `beanName`
* Check for parent `BeanDefinition` in the `IntegrationFlowBeanPostProcessor`
before calling its meta-info
* Fix tests according new `IntegrationObjectSupport.toString()` behavior
Unsophisticated Avro transformers for `SpecificRecord` implementations.
* * Fix DSL Factory
- transformer was changed to `<? extends GenericContainer>`; change the DSL to match
* * Restore test log4j
* * Revert to supporting only SpecificRecord
* * Fix assert
* * Add multi-type deserialization with fluent API
* Polishing for PR comments
* * Remove type mappings; Exxpression now returns the type (or class name)
* Cache types created from class names
* Add type header in "toAvro" transformer
* * Remove the type cache (already handled by the class loader)
* * Don't convert the class to String in the "toAvro" transformer
JIRA: https://jira.spring.io/browse/INT-2480
* Introduce `headers-function` option into the `aggregator` for merging
and computing headers for the output message based on the completed
group
* Implement a `DefaultAggregateHeadersFunction` and use it in the
`AbstractAggregatingMessageGroupProcessor` for default behavior with
possible injection for any other implementation
* Add `DelegatingMessageGroupProcessor` to wrap any other
`MessageGroupProcessor` implementations with possible usage of the
`headersFunction` if result is not a `Message` or `MessageBuilder`
* Make `AbstractCorrelatingMessageHandler.getOutputProcessor()` as
`public` rto give access to this option from the `AggregatorSpec` to
be able to inject a `headersFunction` in Java DSL configuration
* Add `AbstractIntegrationMessageBuilder.getHeader()` to get access to
some underlying header avoiding extra `Map` in case of `getHeaders()`
* Change a logic in the `AbstractMessageProducingHandler.produceOutput()`
to consult a `reply` for the `replyChannel` as well `routingSlip` header
if the `reply` is a `Message` or `MessageBuilder`
* Introduce a `AbstractMessageProducingHandler.messageBuilderForReply()`
and use it in `AbstractMessageSplitter` to avoid duplication
* Validate a new functionality in tests
* Fix `FileOutboundGatewayParserTests` to rely on the `TemporaryFolder`
to clean up test files after using
* JavaDocs for `DefaultAggregateHeadersFunction`
* Some `router.adoc` polishing
* Fix link to Reactor in the `router.adoc`
* Add docs for new `Function<MessageGroup, Map<String, Object>>` strategy
* Doc polishing.
* Fix `SmartLifecycle.stop(Runnable)` usage
We always have to call `callback` in the `SmartLifecycle.stop(Runnable)`
implementation independently of component state
* Fix `StandardIntegrationFlow.stop(Runnable)` for a logic when we
don't have any `this.lifecycles`
* Remove those `stop(Runnable)` which are fully equivalent of the
`default` on in the `SmartLifecycle`
* Some other simple polishing for the affected classes, e.g.
`isSingleton()` is `default` with `true` in the `InitializingBean`
**Cherry-pick to 5.1.x**
* * Fix checkstyle violation
* GH-2967: Fix ScatterGatherH for headers copy
Fixes https://github.com/spring-projects/spring-integration/issues/2967
The `ChannelInterceptor` is added into the `this.gatherChannel` on each
request message making a subsequent requests for scatter-gather as
halting on reply.
* Add an interceptor into an injected `this.gatherChannel` only once
during `ScatterGatherHandler` initialization
* Introduce `ORIGINAL_REPLY_CHANNEL` and `ORIGINAL_ERROR_CHANNEL`
headers to carry a request reply and error channels from headers
* Populate `REPLY_CHANNEL` and `ERROR_CHANNEL` headers back before
sending scattering replies into gatherer
* Transfer a `GATHER_RESULT_CHANNEL` header now directly from the scatter
message to make it available in the reply from the gatherer
* Add note about those headers in the `scatter-gather.adoc`
* Modify `ScatterGatherTests` to be sure that `ScatterGatherHandler`
works for several requests
**Cherry-pick to 5.1.x**
* * Fix language in doc
