The Spring for Apache Kafka project now requires Spring Framework 5.0 and Java 8.
You can now annotate @KafkaListener methods (and classes, and @KafkaHandler methods) with @SendTo.
If the method returns a result, it is forwarded to the specified topic.
See the section called “Forwarding Listener Results using @SendTo” for more information.
Message listeners can now be aware of the Consumer object.
See the section called “Message Listeners” for more information.
Rebalance listeners can now access the Consumer object during rebalance notifications.
See the section called “Rebalance Listeners” for more information.
For convenience a test class level @EmbeddedKafka annotation is provided with the purpose to register KafkaEmbedded as a bean.
See Section 4.3, “Testing Applications” for more information.
==== After rollback processing
Starting with version 2.0.5, a new AfterRollbackProcessor strategy is provided - see the section called “After Rollback Processor” for more information.
