## org.springframework.jms.listener
Interface SessionAwareMessageListener<M extends javax.jms.Message>

All Known Implementing Classes:
  JmsInvokerServiceExporter, MessageListenerAdapter, MessageListenerAdapter102

    public interface SessionAwareMessageListener<M extends javax.jms.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
