Package org.springframework.jms.listener

Interface SessionAwareMessageListener<M extends Message>

Type Parameters:

M - the message type

All Known Implementing Classes:

AbstractAdaptableMessageListener, MessageListenerAdapter, MessagingMessageListenerAdapter

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SessionAwareMessageListener<M extends Message>

Variant of the standard JMS MessageListener interface, offering not only the received Message but also the underlying JMS Session object. The latter can be used to send reply messages, without the need to access an external Connection/Session, i.e. without the need to access the underlying ConnectionFactory.

Supported by Spring's DefaultMessageListenerContainer and SimpleMessageListenerContainer, as direct alternative to the standard JMS MessageListener interface. Typically not supported by JCA-based listener containers: For maximum compatibility, implement a standard JMS MessageListener instead.

Since:

2.0
