On behalf of the Spring Integration team I am pleased to announce that the fifth milestone for the Spring Integration 5.0 release (5.0.0.M5) is now available.

21 JIRAs (and some GitHub issues) made into this release, including bug fixes and a number of new features. Some highlights of features in M4 and M5, since the previously announced Milestone 3:

• The Splitter now can deal with the Java Stream and Reactor Flux payloads. If the output channel is a ReactiveStreamsSubscribableChannel, splitting supports back-pressure.

• A ErrorMessagePublisher together with the ErrorMessageStrategy have been introduced to pursue better error handling experience with the inception message for the ErrorMessage. The MessageListenerContainer in Spring Kafka 2.0 and Spring AMQP 2.0 are supplied with their own ErrorMessageStrategy to represent the original data in the ErrorMessage for the error handling flow.

• The new MockMessageHandler has been added to Spring Integration Test framework for replacing real `MessageHandler`s for unit testing:

  MessageHandler mockMessageHandler = mockMessageHandler() .handleNextAndReply(m -> m.getPayload().toString().toUpperCase());

  this.mockIntegrationContext .substituteMessageHandlerFor("myServiceActivator", mockMessageHandler);

  this.pojoServiceChannel.send(new GenericMessage<>("foo")); receive = this.results.receive(10000);

  assertEquals("FOO", receive.getPayload());

On behalf of the Spring Integration team, I am pleased to announce that the 4.3.10.RELEASE of Spring Integration is now available.

This release contains a few important bug fixes as well as a couple of improvements.

One of the most interesting feature is customized Jackson ObjectMapper which is aware of Message and MessageHeaders serialization/deserialization to/from JSON. This functionality is useful in those components which allow to configure custom serializer/deserializer, for example RedisMessageStore:

RedisMessageStore store = new RedisMessageStore(redisConnectionFactory);

ObjectMapper…

The Spring Integration team is pleased to announce that the third milestone for the Spring Integration 5.0 release (5.0.0.M3) is now available.

53 JIRAs (and some GitHub issues) made into this release, including bug fixes and a number of new features. Some highlights since the previous Milestone 2:

• Initial implementation for a Spring Integration Testing Framework - the @SpringIntegrationTest annotation for test classes and MockIntegration factory help you to write unit tests for integration flows and channel adapters. We intend to flush out this capability with more features before GA, including more mocking, verifications and some send-and-receive utilities to test components in isolation. Feedback is welcome!

• POJO handler method invocations (@ServiceActivator, @Transformer etc., or such methods invoked from XML definitions) now use InvocableHandlerMethod by default. Together with the ConfigurableCompositeMessageConverter and @Default utilities that allows us to implement conditional method invocation scenarios based on the Content-Type and target method arguments resolution. To restore the previous SpEL-based behavior, the @UseSpelInvoker method-level annotation is provided.

It is my pleasure to announce that the Spring for Apache Kafka 1.1.3 maintenance release is available now.

As usual, thanks to the community for any feedback and contribution as always. Looking forward for more!

This release contains several bug fixes, including proper offset commit handling when using a BatchListener; therefore an upgrade is highly recommended.

Right now master has been switched to the version 2.0 for Java 8 and Spring Framework 5.0 code base. We have some plans for high-level API for Kafka Streams and Reactor Kafka support.
