public abstract class AbstractMessageListenerContainer
extends AbstractJmsListeningContainer
implements MessageListenerContainer

Abstract base class for Spring message listener container implementations. Can either host a standard JMS MessageListener or Spring's SessionAwareMessageListener for actual message processing.

Usually holds a single JMS Connection that all listeners are supposed to be registered on, which is the standard JMS way of managing listener sessions. Can alternatively also be used with a fresh Connection per listener, for Java EE style XA-aware JMS messaging. The actual registration process is up to concrete subclasses.

NOTE: The default behavior of this message listener container is to never propagate an exception thrown by a message listener up to the JMS provider. Instead, it will log any such exception at the error level. This means that from the perspective of the attendant JMS provider no such listener will ever fail. However, if error handling is necessary, then any implementation of the ErrorHandler strategy may be provided to the setErrorHandler(ErrorHandler) method. Note that JMSExceptions will be passed to the ErrorHandler in addition to (but after) being passed to an ExceptionListener, if one has been provided.

The listener container offers the following message acknowledgment options:

• "sessionAcknowledgeMode" set to "AUTO_ACKNOWLEDGE" (default): This mode is container-dependent: For DefaultMessageListenerContainer, it means automatic message acknowledgment before listener execution, with no redelivery in case of an exception and no redelivery in case of other listener execution interruptions either. For SimpleMessageListenerContainer, it means automatic message acknowledgment after listener execution, with no redelivery in case of a user exception thrown but potential redelivery in case of the JVM dying during listener execution. In order to consistently arrange for redelivery with any container variant, consider "CLIENT_ACKNOWLEDGE" mode or - preferably - setting "sessionTransacted" to "true" instead.
• "sessionAcknowledgeMode" set to "DUPS_OK_ACKNOWLEDGE": Lazy message acknowledgment during (DefaultMessageListenerContainer) or shortly after (SimpleMessageListenerContainer) listener execution; no redelivery in case of a user exception thrown but potential redelivery in case of the JVM dying during listener execution. In order to consistently arrange for redelivery with any container variant, consider "CLIENT_ACKNOWLEDGE" mode or - preferably - setting "sessionTransacted" to "true" instead.
• "sessionAcknowledgeMode" set to "CLIENT_ACKNOWLEDGE": Automatic message acknowledgment after successful listener execution; best-effort redelivery in case of a user exception thrown as well as in case of other listener execution interruptions (such as the JVM dying).
• "sessionTransacted" set to "true": Transactional acknowledgment after successful listener execution; guaranteed redelivery in case of a user exception thrown as well as in case of other listener execution interruptions (such as the JVM dying).

There are two solutions to the duplicate message processing problem:

• Either add duplicate message detection to your listener, in the form of a business entity existence check or a protocol table check. This usually just needs to be done in case of the JMSRedelivered flag being set on the incoming message (otherwise just process straightforwardly). Note that with "sessionTransacted" set to "true", duplicate messages will only appear in case of the JVM dying at the most unfortunate point possible (i.e. after your business logic executed but before the JMS part got committed), so duplicate message detection is just there to cover a corner case.
• Or wrap your entire processing with an XA transaction, covering the reception of the JMS message as well as the execution of the business logic in your message listener (including database operations etc). This is only supported by DefaultMessageListenerContainer, through specifying an external "transactionManager" (typically a JtaTransactionManager, with a corresponding XA-aware JMS ConnectionFactory passed in as "connectionFactory").

Note that XA transaction coordination adds significant runtime overhead, so it might be feasible to avoid it unless absolutely necessary.

Recommendations:

• The general recommendation is to set "sessionTransacted" to "true", typically in combination with local database transactions triggered by the listener implementation, through Spring's standard transaction facilities. This will work nicely in Tomcat or in a standalone environment, often combined with custom duplicate message detection (if it is unacceptable to ever process the same message twice).
• Alternatively, specify a JtaTransactionManager as "transactionManager" for a fully XA-aware JMS provider - typically when running on a Java EE server, but also for other environments with a JTA transaction manager present. This will give full "exactly-once" guarantees without custom duplicate message checks, at the price of additional runtime processing overhead.

Note that the "sessionTransacted" flag is strongly recommended over JmsTransactionManager, provided that transactions do not need to be managed externally. As a consequence, set the transaction manager only if you are using JTA or if you need to synchronize with custom external transaction arrangements.

Specify concurrency limits.

setDestination

public void setDestination(@Nullable
                           Destination destination)

Set the destination to receive messages from.

Alternatively, specify a "destinationName", to be dynamically resolved via the DestinationResolver.

Note: The destination may be replaced at runtime, with the listener container picking up the new destination immediately (works e.g. with DefaultMessageListenerContainer, as long as the cache level is less than CACHE_CONSUMER). However, this is considered advanced usage; use it with care!

See Also:

setDestinationName(String)

getDestination

@Nullable
public Destination getDestination()

Return the destination to receive messages from. Will be null if the configured destination is not an actual Destination type; c.f. when the destination is a String.

setDestinationName

public void setDestinationName(@Nullable
                               String destinationName)

Set the name of the destination to receive messages from.

The specified name will be dynamically resolved via the configured destination resolver.

Alternatively, specify a JMS Destination object as "destination".

Note: The destination may be replaced at runtime, with the listener container picking up the new destination immediately (works e.g. with DefaultMessageListenerContainer, as long as the cache level is less than CACHE_CONSUMER). However, this is considered advanced usage; use it with care!

See Also:

setDestination(javax.jms.Destination)

Return a descriptive String for this container's JMS destination (never null).

setMessageSelector

public void setMessageSelector(@Nullable
                               String messageSelector)

Set the JMS message selector expression (or null if none). Default is none.

See the JMS specification for a detailed definition of selector expressions.

Note: The message selector may be replaced at runtime, with the listener container picking up the new selector value immediately (works e.g. with DefaultMessageListenerContainer, as long as the cache level is less than CACHE_CONSUMER). However, this is considered advanced usage; use it with care!

getMessageSelector

@Nullable
public String getMessageSelector()

Return the JMS message selector expression (or null if none).

setMessageListener

public void setMessageListener(@Nullable
                               Object messageListener)

Set the message listener implementation to register. This can be either a standard JMS MessageListener object or a Spring SessionAwareMessageListener object.

Note: The message listener may be replaced at runtime, with the listener container picking up the new listener object immediately (works e.g. with DefaultMessageListenerContainer, as long as the cache level is less than CACHE_CONSUMER). However, this is considered advanced usage; use it with care!

Throws:

IllegalArgumentException - if the supplied listener is not a MessageListener or a SessionAwareMessageListener

checkMessageListener

protected void checkMessageListener(@Nullable
                                    Object messageListener)

Check the given message listener, throwing an exception if it does not correspond to a supported listener type.

By default, only a standard JMS MessageListener object or a Spring SessionAwareMessageListener object will be accepted.

Parameters:

messageListener - the message listener object to check

Throws:

IllegalArgumentException - if the supplied listener is not a MessageListener or a SessionAwareMessageListener

Determine the default subscription name for the given message listener.

Parameters:

messageListener - the message listener object to check

Returns:

the default subscription name

See Also:

SubscriptionNameProvider

setSubscriptionDurable

public void setSubscriptionDurable(boolean subscriptionDurable)

Set whether to make the subscription durable. The durable subscription name to be used can be specified through the "subscriptionName" property.

Default is "false". Set this to "true" to register a durable subscription, typically in combination with a "subscriptionName" value (unless your message listener class name is good enough as subscription name).

Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the "pubSubDomain" flag as well.

See Also:

setSubscriptionName(java.lang.String), JmsDestinationAccessor.setPubSubDomain(boolean)

isSubscriptionDurable

public boolean isSubscriptionDurable()

Return whether to make the subscription durable.

setSubscriptionShared

public void setSubscriptionShared(boolean subscriptionShared)

Set whether to make the subscription shared. The shared subscription name to be used can be specified through the "subscriptionName" property.

Default is "false". Set this to "true" to register a shared subscription, typically in combination with a "subscriptionName" value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with "subscriptionDurable" as well.

Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the "pubSubDomain" flag as well.

Requires a JMS 2.0 compatible message broker.

Since:

4.1

public void setSubscriptionName(@Nullable
                                String subscriptionName)

Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription.

The subscription name needs to be unique within this client's JMS client id. Default is the class name of the specified message listener.

Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0).

public void setMessageConverter(@Nullable
                                MessageConverter messageConverter)

Set the MessageConverter strategy for converting JMS Messages.

Since:

4.1

getMessageConverter

@Nullable
public MessageConverter getMessageConverter()

Description copied from interface: MessageListenerContainer

Return the MessageConverter that can be used to convert Message, if any.

Specified by:

getMessageConverter in interface MessageListenerContainer

setExceptionListener

public void setExceptionListener(@Nullable
                                 ExceptionListener exceptionListener)

Set the JMS ExceptionListener to notify in case of a JMSException thrown by the registered message listener or the invocation infrastructure.

getExceptionListener

@Nullable
public ExceptionListener getExceptionListener()

Return the JMS ExceptionListener to notify in case of a JMSException thrown by the registered message listener or the invocation infrastructure, if any.

setErrorHandler

public void setErrorHandler(@Nullable
                            ErrorHandler errorHandler)

Set the ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message.

By default, there will be no ErrorHandler so that error-level logging is the only result.

getErrorHandler

@Nullable
public ErrorHandler getErrorHandler()

Return the ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message.

Since:

4.1

setExposeListenerSession

public void setExposeListenerSession(boolean exposeListenerSession)

Set whether to expose the listener JMS Session to a registered SessionAwareMessageListener as well as to JmsTemplate calls.

Default is "true", reusing the listener's Session. Turn this off to expose a fresh JMS Session fetched from the same underlying JMS Connection instead, which might be necessary on some JMS providers.

Note that Sessions managed by an external transaction manager will always get exposed to JmsTemplate calls. So in terms of JmsTemplate exposure, this setting only affects locally transacted Sessions.

See Also:

SessionAwareMessageListener

isExposeListenerSession

public boolean isExposeListenerSession()

Return whether to expose the listener JMS Session to a registered SessionAwareMessageListener.

setAcceptMessagesWhileStopping

public void setAcceptMessagesWhileStopping(boolean acceptMessagesWhileStopping)

Set whether to accept received messages while the listener container in the process of stopping.

Default is "false", rejecting such messages through aborting the receive attempt. Switch this flag on to fully process such messages even in the stopping phase, with the drawback that even newly sent messages might still get processed (if coming in before all receive timeouts have expired).

NOTE: Aborting receive attempts for such incoming messages might lead to the provider's retry count decreasing for the affected messages. If you have a high number of concurrent consumers, make sure that the number of retries is higher than the number of consumers, to be on the safe side for all potential stopping scenarios.

isAcceptMessagesWhileStopping

public boolean isAcceptMessagesWhileStopping()

Return whether to accept received messages while the listener container in the process of stopping.

protected void handleListenerException(Throwable ex)

Handle the given exception that arose during listener execution.

The default implementation logs the exception at warn level, not propagating it to the JMS provider — assuming that all handling of acknowledgement and/or transactions is done by this listener container. This can be overridden in subclasses.

Parameters:

ex - the exception to handle

invokeExceptionListener

protected void invokeExceptionListener(JMSException ex)

Invoke the registered JMS ExceptionListener, if any.

Parameters:

ex - the exception that arose during JMS processing

See Also:

setExceptionListener(javax.jms.ExceptionListener)

invokeErrorHandler

protected void invokeErrorHandler(Throwable ex)

Invoke the registered ErrorHandler, if any. Log at warn level otherwise.

Parameters:

ex - the uncaught error that arose during JMS processing.

setErrorHandler(org.springframework.util.ErrorHandler)
