Fixes https://github.com/spring-projects/spring-integration/issues/3204
* Add an `intercept(ChannelInterceptor...)` method into `BaseIntegrationFlowDefinition`
to register one or more channel interceptors at the current flow position.
* refactor to reuse `InterceptableChannel` creation from `wireTap`
* document the new operator
* GH-3183: Add ReactiveRequestHandlerAdvice
Fixes https://github.com/spring-projects/spring-integration/issues/3183
* Introduce a `ReactiveRequestHandlerAdvice` with a `BiFunction<Message<?>, Mono<?>, Publisher<?>>`
logic to apply a `Mono.transform()` operator for a returned from the handler `Mono` reply
* Fix `WebFluxRequestExecutingMessageHandler` to return a `Mono.then()` instead of an explicit subscription -
it happens downstream anyway during reply producing with a proper error handling, too
* Demonstrate `ReactiveRequestHandlerAdvice` in the `RSocketDslTests` - without `retry()` it fails
* Add `ConsumerEndpointSpec.customizeMonoReply()` for convenience
* Document `ReactiveRequestHandlerAdvice` feature
* * Fix language in docs
* Add Reactive TX Manager support
* Change `TransactionInterceptorBuilder` and `TransactionHandleMessageAdvice` to reply
on a generic `TransactionManager`, so we can configure reactive one as well
* Change a `<transactional>` XML element to support a generic `TransactionManager` reference,
so we can configure reactive one as well
* Support `adviceChain` configuration for the `ReactiveMessageHandler` in the `ConsumerEndpointFactoryBean`
* Attemp to apply reactive transaction for the Reactive MongoDB channel adapter
* * Revert `MongoDbTests` change -
to support transactions we need the latest MongoDb server with replica enabled
* Document reactive transactions
* * Address PR reviews
It is better to poll message from `QueueChannel`
when ever a reactive request happens.
The `Mono.fromCallable()` operator does poll on subscription, not request
and caches the value.
However we may lose such a value in between.
* Use `Mono.create()` with its `monoSink.onRequest()` callback in the
`adaptPollableChannelToPublisher()` implementation to defer `inputChannel.receive()`
until an on demand request downstream
* GH-3192: pub-sub DSL for broker-backed channels
Fixes https://github.com/spring-projects/spring-integration/issues/3192
* Introduce a `BroadcastCapableChannel` abstract to indicate those `SubscribableChannel`
implementations which can provide a pub-sub functionality
* Implement a `BroadcastCapableChannel` in broker-baked channels with pub-sub option
* Introduce a `BaseIntegrationFlowDefinition.publishSubscribeChannel()` based
on the `BroadcastCapableChannel` and `BroadcastPublishSubscribeSpec` to let to
configure sub-flow subscribers in fluent manner
* * Add some JavaDocs and document new feature
* * Show the channel bean definition in the doc
* Fix typo
To support `onErrorContinue()` logic for the plain `Subscriber`
we need to wrap its `onNext()` into a `try..catch` and respective
`errorHandler` in the `ReactiveStreamsConsumer`
https://build.spring.io/browse/INT-MASTERSPRING40-978
Investigate a behaviour for `ReactiveStreamsConsumer`
when we use a plain `Subscriber` directly instead of `doOn...` callbacks.
It looks like there is some race condition when the data can be consumed
upstream, but there is no consumer downstream ready yet
* GH-3155: Add support for Java DSL extensions
Fixes https://github.com/spring-projects/spring-integration/issues/3155
Provide an `IntegrationFlowExtension` for possible custom EI-operators
in the target project use-cases.
* * Move `IntegrationFlowExtension` tests ot its own test class
* Make all the `IntegrationComponentSpec` ctors as `protected` for possible custom extensions
* Make some `BaseIntegrationFlowDefinition` methods and properties as `protected` to get them
access from the `IntegrationFlowExtension` implementations
* Document the feature
* * Fix language and typos in docs
* * Add `protected` to one more `GatewayEndpointSpec` ctor
* Add JavaDocs to `GatewayEndpointSpec` methods
* * Add `protected` to one more `JmsPollableMessageChannelSpec` ctor
Fixes https://github.com/spring-projects/spring-integration/issues/3157
* Fixed issue with sequences not being popped when Output processor returns a message.
* Updated documents and added additional Checks to the testcase to ensure proper `popSequence` is done.
* Updated documents and added corrected code formatting
* Updated documents and used headerAccessor Constants for matching headers
* Clean up code style
* Improve docs for the feature on the matter
* Gradle 6.1.1
* MongoDb 4.0
* Other Spring dependencies to `BUILD-SNAPSHOT`
* Fix MongoDb tests according latest Spring Data
* State in the docs that both MongoDb driver are `optional` now in the dependencies
* Populate a JsonHeaders.RESOLVABLE_TYPE on reply
Fixes https://github.com/spring-projects/spring-integration-samples/issues/277
In the `AbstractAmqpOutboundEndpoint` the `JsonHeaders.RESOLVABLE_TYPE`
from request message is copied to reply message making inconsistency downstream.
The `JsonToObjectTransformer` consults first a `JsonHeaders.RESOLVABLE_TYPE`
and deserialize payload to wrong type
* Fix `DefaultAmqpHeaderMapper` to populate a `JsonHeaders.RESOLVABLE_TYPE`
alongside with other `JsonHeaders` populated from the reply AMQP message.
This way a `JsonHeaders.RESOLVABLE_TYPE` from request message won't have effect
* To get access to classes, supply `AbstractHeaderMapper` with a bean factory `ClassLoader`
* Introduce a couple utility methods into `JsonHeaders` for building a `ResolvableType`
**Cherry-pick to 5.2.x**
* * Fix code formatting for arguments wrapping
Fixes https://github.com/spring-projects/spring-integration/issues/3152
The upstream `gatherResultChannel` header has been missed when we produced a reply from nested scatter-gather
Added Test Case for Nested Scatter Gather test
Simplified the the test cases and added author in changed cases
Corrected codestyle issue in Travis CI
Removed additional OriginalReplyChannel and originalErrorChannel in Headers.
Added additional not to be executed line of code in test case.
Restored OriginalErrorChannel Header and removed error handling related fixes
* Clean up code style and improve readability
**Cherry-pick to 5.1.x & master**
* Migrate `RouterTests` to JUnit 5
The `ReactiveStreamsConsumerTests.testReactiveStreamsConsumerPollableChannel()`
fails periodically.
Change the logic to rely on the `FluxSink.OverflowStrategy.BUFFER` for
possible future subscribers, meanwhile with `IGNORE` we just lose a message
altogether
It turns out that some upstream fluxes may come with the
`onErrorResume()` logic.
The `onErrorContinue()` here downstream in the `FluxMessageChannel.java`
eliminates an `onErrorResume()` purpose.
* Change the logic to `try..catch` in the `doOnNext()` instead and let
that upstream `onErrorResume()` to do its job
https://build.spring.io/browse/INT-MASTERSPRING40-954/
The `ReactiveStreamsConsumerTests` fails with some race condition from time to time.
Possible reason that no one endpoint is stopped in the end of test.
Even if we step out from the test method, background threads are still active
Resolves https://github.com/spring-projects/spring-amqp/issues/1142
Resize down does not work when not enough already allocated to match the reduction.
Improved SimplePool test cases and fixed code style
Fixed code style
GH-3143: Test Polishing
- use preferred assertJ expected exception checking
- add a test for reducing a partially allocated pool
- check active counts
It turns out that some downstream projects are going to
support both Spring Boot 2.2 and 2.3 versions (Spring Cloud).
This way they are going to compile against Spring Integration 5.2,
but possible have a runtime against Spring Integration 5.3.
* Restore `IntegrationFlowDefinition` from the previous version
to keep binary compatibility at runtime
* Messaging Annotations: process ReactiveMH
* Add support for `ReactiveMessageHandler` as a `@ServiceActivator` bean
* Wrap `ReactiveMessageHandler` in the `ReactiveMessageHandlerAdapter`
in the `ServiceActivatorAnnotationPostProcessor`
* Unwrap `ReactiveMessageHandlerAdapter` in the `AbstractMethodAnnotationPostProcessor`
for `ReactiveStreamsConsumer`
* * Add documentation for the `ReactiveMessageHandler`
& Reactive MongoDb channel adapters
* Infrastructure for ReactiveMessageHandler
We have now a `ReactiveMongoDbStoringMessageHandler` which implements
a `ReactiveMessageHandler`, but not a `MessageHandler` for possible
deferred subscriptions to the returned Reactor type
We don't have a proper application context processing for this
new type of message handlers
* Change a `ConsumerEndpointFactoryBean` to apply an `MH` and `RMH`
as possible types for handler
* Introduce a `ReactiveMessageHandlerAdapter` to wrap an `RMH`
into a `MH` for synchronous calls in the regular consumer endpoints
* Wrap an `RMH` into a `ReactiveMessageHandlerAdapter` for regular
endpoints and unwrap for `ReactiveStreamsConsumer`
* Add `RMH`-based ctor into `ReactiveStreamsConsumer` for target
reactive streams composition (`flatMap()` on the `RMH`)
* Remove a `DelegatingSubscriber` from the `ReactiveStreamsConsumer`
in favor of direct calls from the `doOnSubscribe()`, `doOnComplete()`
& `doOnNext()`
* Add an `onErrorContinue()` to handle per-message errors, but don't
cancel the whole source `Publisher`
* Use `Disposable` from the `subscribe()` to cancel in the `stop()`
- recommended way in Reactor
* Use `onErrorContinue()` in the `FluxMessageChannel` instead of
`try..catch` in the `doOnNext()` - for possible `onErrorStop()`
in the provided upstream `Publisher`
* Handle `RMH` in the `ServiceActivatorFactoryBean` as a direct handler
as well with wrapping into `ReactiveMessageHandlerAdapter` for return.
The `ConsumerEndpointFactoryBean` extracts an `RMH` from the adapter
for the `ReactiveStreamsConsumer` anyway
* Add XML parsing test for `ReactiveMongoDbStoringMessageHandler`
* Add `log4j-slf4j-impl` for all the test runtime since `slf4j-api`
comes as a transitive dependency from many places
* * Fix conflicts after rebasing to master
* * Fix typo in warn message
* Change `Assert.state()` to `Assert.isTrue()`
for `ConsumerEndpointFactoryBean.setHandler()`
* * Fix `ConsumerEndpointFactoryBean` when reactive and no advice-chain
* Fix race condition in the
`ReactiveMongoDbStoringMessageHandlerTests.testReactiveMongoMessageHandlerFromApplicationContext()`
* * Handle `ReactiveMessageHandler` in Java DSL.
Essentially request a wrapping into `ReactiveMessageHandlerAdapter`.
Describe such a requirements in the `ReactiveMessageHandlerAdapter` JavaDocs
* Some Java DSL test polishing
* Add Java DSL for `ReactiveMongoDbStoringMessageHandler`
* Propagate missed `ApplicationContext` population into an internally
created `ReactiveMongoTemplate` in the `ReactiveMongoDbStoringMessageHandler`
* Remove Boon dependency and its usage
* Remove overloaded methods from the `IntegrationFlowDefinition`
- we can simply rely now on the super class
* Remove (or rework) deprecated entities in the docs
* Fix tests for removed deprecated APIs
* Rework affected tests to JUnit 5
Fixes https://github.com/spring-projects/spring-integration/issues/3132
It turns out that Checkstyle EmptyBlock doesn't complain about
empty default ctor.
Plus a new check for `super();` call treats it as a violation
* Remove `super();` from all the no-arg ctors
* Code style clean up in the affected classes according
IDEA suggestions
* Fix new Sonar smells
* Alongside with existing `springAmqpVersion` & `springVersion`
also expose `springDataVersion` & `springSecurityVersion`
project properties.
These can be used in external CI plans for compatibility builds
* Fix `IntegrationGraphServerTests` for the current state of graph -
The node name is now based on the endpoint id, not a `MH` bean name
* Fix MongoDB tests for compatibility with the latest driver
* Shorten internal component names for graph
The long `IntegrationContextUtils.ERROR_LOGGER_BEAN_NAME` name
is used for `errorChannel` `LoggingHandler`'s endpoint.
It is too long for endpoint node in the graph meanwhile the
`errorChannel` is good everywhere
* Change an `IntegrationGraphServer` logic to shorten internal
component names before drawing a graph
* Introduce `IntegrationUtils.obtainComponentName()` for
shortening an internal name if any
* Use `IntegrationConfigUtils.BASE_PACKAGE` in the `IntegrationMBeanExporter`
instead of its own static property
* Remove `IntegrationConfigUtils.FACTORY_BEAN_OBJECT_TYPE` in favor
of introduced in SF `FactoryBean.OBJECT_TYPE_ATTRIBUTE`
* Rework affected test classes to JUnit 5
* Remove usage of deprecated options in the `@EnableIntegrationManagement`
* Document names shortening feature for graph
* * Improve `obtainComponentName()` function
