What’s New

This version requires Spring Framework 6.1 and Java 17.

Log messages reporting access refusal due to exclusive consumers are now logged at DEBUG level by default. It remains possible to configure your own logging behavior by setting the exclusiveConsumerExceptionLogger and closeExceptionLogger properties on the listener container and connection factory respectively. In addition, the SimpleMessageListenerContainer consumer restart after such an exception is now logged at DEBUG level by default (previously INFO). A new method logRestart() has been added to the ConditionalExceptionLogger to allow this to be changed. See Consumer Events and [channel-close-logging] for more information.

Connection Factory supported backoff policy when creating connection channel. See Choosing a Connection Factory for more information.
