For the latest stable version, please use Spring Integration 6.3.2! |
Changes between 5.5 and 6.0
New Components
A Groovy DSL implementation for integration flow definitions has been added. See Groovy DSL for more information.
MQTT ClientManager
A new MQTT ClientManager
has been added to support a reusable MQTT connection across different channel adapters.
See Shared MQTT Client Support for more information.
GraphQL Support
The GraphQL support has been added. See GraphQL Support for more information.
Apache Camel Support
Support for Apache Camel routes has been introduced. See Apache Camel Support for more information.
Hazelcast Support
The Hazelcast Spring Integration Extensions project has been migrated as the spring-integration-hazelcast
module.
See Hazelcast Support for more information.
SMB Support
SMB support has been added from the Spring Integration Extensions project.
The Java DSL (see org.springframework.integration.smb.dsl.Smb
factory) also has been added to this module.
An SmbStreamingMessageSource
and SmbOutboundGateway
implementation are introduced.
See SMB Support for more information.
PostgreSQL Push Notification
A PostgresSubscribableChannel
allows to receive push notifications via PostgresChannelMessageTableSubscriber
upon new messages add to the JdbcChannelMessageStore
.
See PostgreSQL: Receiving Push Notifications for more information.
RabbitMQ Stream Queue Support
The AMQP module has been enhanced to provide support for inbound and outbound channel adapters using RabbitMQ Stream Queues. See RabbitMQ Stream Queue Support for more information.
Apache MINA SFTP
The SFTP modules has been fully reworked from outdated JCraft JSch library to more robust and modern org.apache.sshd:sshd-sftp
module of the Apache MINA project.
See SFTP Adapters for more information.
Micrometer Observation
Enabling observation for timers and tracing using Micrometer is now supported. See Micrometer Observation for more information.
GraalVM Polyglot Support
The Scripting module now provides a PolyglotScriptExecutor
implementation based on the GraalVM Polyglot support.
JavaScript support is now based on this executor since its JSR223 implementation has been removed from Java by itself.
See Scripting Support for more information.
Apache Cassandra Support
The Apache Cassandra Spring Integration Extensions project has been migrated as the spring-integration-cassandra
module.
See Apache Cassandra Support for more information.
Kotlin Coroutines
Kotlin Coroutines support has been introduced to the framework.
See Kotlin Coroutines for more information.
Native Images
Support for creating GraalVM native images is provided. See Native Images Support for more information.
General Changes
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.
See Annotation Support for more information.
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.
See Scatter-Gather for more information.
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
.
See Router Options for more information.
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.
See Aggregator for more information.
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.
See Java DSL for more information.
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
.
The Messaging Gateway interface method can now return Future<Void>
and Mono<Void>
with a proper asynchronous execution of the downstream flow.
Alongside with a @MessagingGateway
annotation the interface can also be marked with a @Primary
.
@MessagingGateway
interfaces can now be use as an @Import
resources for configuration.
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
.
See Messaging Gateway for more information.
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
.
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
.
RMI Removal
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.
GemFire Removal
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.
HTTP Changes
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.
Apache Kafka Changes
When providing a RetryTemplate
on the inbound gateway or message-driven channel adapter, if an errorChannel
is also provided, an ErrorMessageSendingRecoverer
is automatically configured.
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.
See Spring for Apache Kafka Support for more information.
JDBC Changes
The DefaultLockRepository
can now be supplied with a PlatformTransactionManager
instead of relying on the primary bean from the application context.
See JDBC Lock Registry for more information.
TCP/IP Changes
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.
See TCP and UDP Support for more information.
JMS Changes
The JmsOutboundGateway
now creates a TemporaryTopic
instead of TemporaryQueue
if replyPubSubDomain
option is set to true
.
See JMS Support for more information.
Security Changes
The ChannelSecurityInterceptor
and its annotation @SecuredChannel
and XML <secured-channels>
configurations have been deprecated in favor of AuthorizationChannelInterceptor
.
See Security Support for more information.
Webflux Request Attributes Support
Webclient Request attributes support has been added for WebFluxRequestExecutingMessageHandler
.
See WebFlux Request Attributes for more information.
