A Groovy DSL implementation for integration flow definitions has been added. See Groovy DSL for more information.spring-doc.cn

The messaging annotations are now @Repeatable and the same type can be declared several times on the same service method. The messaging annotations don’t require a poller attribute as an array of @Poller anymore.spring-doc.cn

See Annotation Support for more information.spring-doc.cn

For convenience, the XML and Java DSL for Scatter-Gather, based on the RecipientListRouter, now sets an applySequence = true, so the gatherer part can rely on the default correlation strategies.spring-doc.cn

See Scatter-Gather for more information.spring-doc.cn

Another convenient behavior change has been made to the AbstractMappingMessageRouter. Now, setting a defaultOutputChannel also resets the channelKeyFallback property to false, so no attempts will be made to resolve a channel from its key, but the logic immediately falls back to sending the message to the defaultOutputChannel.spring-doc.cn

See Router Options for more information.spring-doc.cn

The AggregatingMessageHandler now does not split a Collection<Message<?>> result of the MessageGroupProcessor (unless it is a SimpleMessageGroupProcessor) on the output, but emits a single message containing this whole collection as a payload.spring-doc.cn

See Aggregator for more information.spring-doc.cn

The IntegrationFlows factory is now marked as deprecated in favor of the fluent API available in the IntegrationFlow interface itself. The factory class will be removed in the future releases.spring-doc.cn

See Java DSL for more information.spring-doc.cn

The org.springframework.util.concurrent.ListenableFuture has been deprecated starting with Spring Framework 6.0. All Spring Integration async API has been migrated to the CompletableFuture.spring-doc.cn

The Messaging Gateway interface method can now return Future<Void> and Mono<Void> with a proper asynchronous execution of the downstream flow.spring-doc.cn

Alongside with a @MessagingGateway annotation the interface can also be marked with a @Primary.spring-doc.cn

@MessagingGateway interfaces can now be use as an @Import resources for configuration.spring-doc.cn

The default naming strategy for gateway proxy beans can be customized via @IntegrationComponentScan.nameGenerator() attribute. If AnnotationConfigUtils.CONFIGURATION_BEAN_NAME_GENERATOR bean is present, it is consulted otherwise before falling back to the AnnotationBeanNameGenerator.spring-doc.cn

See Messaging Gateway for more information.spring-doc.cn

The integrationGlobalProperties bean is now declared by the framework as an instance of org.springframework.integration.context.IntegrationProperties instead of the previously deprecated java.util.Properties.spring-doc.cn

Message handlers which produce a collection as a reply (e.g. JpaOutboundGateway, JdbcOutboundGateway and other DB-based gateways) now return an empty result list if no records are returned by the query. Previously, null was returned ending the flow, or throwing an exception, depending on requiresReply.spring-doc.cn

The spring-integration-rmi module has been removed altogether after being deprecated in previous versions. There is no replacement: it is recommended to migrate to more secure network and application protocols, such as WebSockets, RSockets, gRPC or REST.spring-doc.cn

The spring-integration-gemfire module has been removed altogether since there is no Spring Data 2022.0.0 support for VMware GemFire or Apache Geode.spring-doc.cn

The #cookies variable for expression evaluation context, exposed in the HttpRequestHandlingEndpointSupport, is now a MultiValueMap to carry all the values for cookies set by the client. See HTTP Support for more information.spring-doc.cn

When providing a RetryTemplate on the inbound gateway or message-driven channel adapter, if an errorChannel is also provided, an ErrorMessageSendingRecoverer is automatically configured.spring-doc.cn

In addition, the new KafkaErrorMessageSendingRecoverer is provided; this can be used with a DefaultErrorHandler to avoid issues with long aggregated retry delays causing partitions rebalances.spring-doc.cn

See Spring for Apache Kafka Support for more information.spring-doc.cn

The DefaultLockRepository can now be supplied with a PlatformTransactionManager instead of relying on the primary bean from the application context.spring-doc.cn

See JDBC Lock Registry for more information.spring-doc.cn

The lookupHost property of the AbstractConnectionFactory and DatagramPacketMessageMapper is now set to false by default to avoid delays in the environments where DNS is not configured.spring-doc.cn

See TCP and UDP Support for more information.spring-doc.cn

The JmsOutboundGateway now creates a TemporaryTopic instead of TemporaryQueue if replyPubSubDomain option is set to true.spring-doc.cn

See JMS Support for more information.spring-doc.cn

The ChannelSecurityInterceptor and its annotation @SecuredChannel and XML <secured-channels> configurations have been deprecated in favor of AuthorizationChannelInterceptor.spring-doc.cn

See Security Support for more information.spring-doc.cn

Webclient Request attributes support has been added for WebFluxRequestExecutingMessageHandler.spring-doc.cn

See WebFlux Request Attributes for more information.spring-doc.cn
