Class StandardJmsActivationSpecFactory

java.lang.Object

org.springframework.jms.listener.endpoint.StandardJmsActivationSpecFactory

All Implemented Interfaces:

JmsActivationSpecFactory

Direct Known Subclasses:

DefaultJmsActivationSpecFactory

public class StandardJmsActivationSpecFactory
extends Object
implements JmsActivationSpecFactory

Standard implementation of the JmsActivationSpecFactory interface. Supports the standard JMS properties as defined by the JMS 1.5 specification (Appendix B); ignores Spring's "maxConcurrency" and "prefetchSize" settings.

The 'activationSpecClass' property is required, explicitly defining the fully-qualified class name of the provider's ActivationSpec class (e.g. "org.apache.activemq.ra.ActiveMQActivationSpec").

Check out DefaultJmsActivationSpecFactory for an extended variant of this class, supporting some further default conventions beyond the plain JMS 1.5 specification.

2.5

StandardJmsActivationSpecFactory

public StandardJmsActivationSpecFactory()

Method Detail

setActivationSpecClass

public void setActivationSpecClass(Class<?> activationSpecClass)

Specify the fully-qualified ActivationSpec class name for the target provider (e.g. "org.apache.activemq.ra.ActiveMQActivationSpec").

setDefaultProperties

public void setDefaultProperties(Map<String,String> defaultProperties)

Specify custom default properties, with String keys and String values.

Applied to each ActivationSpec object before it gets populated with listener-specific settings. Allows for configuring vendor-specific properties beyond the Spring-defined settings in JmsActivationSpecConfig.

setDestinationResolver

public void setDestinationResolver(DestinationResolver destinationResolver)

Set the DestinationResolver to use for resolving destination names into the JCA 1.5 ActivationSpec "destination" property.

If not specified, destination names will simply be passed in as Strings. If specified, destination names will be resolved into Destination objects first.

Note that a DestinationResolver for use with this factory must be able to work without an active JMS Session: e.g. JndiDestinationResolver or BeanFactoryDestinationResolver but not DynamicDestinationResolver.

getDestinationResolver

public DestinationResolver getDestinationResolver()

Return the DestinationResolver to use for resolving destinations names.

createActivationSpec

public ActivationSpec createActivationSpec(ResourceAdapter adapter,
                                           JmsActivationSpecConfig config)

Description copied from interface: JmsActivationSpecFactory

Create a JCA 1.5 ActivationSpec object based on the given JmsActivationSpecConfig object.

Specified by:

createActivationSpec in interface JmsActivationSpecFactory

Parameters:

adapter - the ResourceAdapter to create an ActivationSpec object for

config - the configured object holding common JMS settings

Returns:

the provider-specific JCA ActivationSpec object, representing the same settings

determineActivationSpecClass

protected Class<?> determineActivationSpecClass(ResourceAdapter adapter)

Determine the ActivationSpec class for the given ResourceAdapter, if possible. Called if no 'activationSpecClass' has been set explicitly

Parameters:

adapter - the ResourceAdapter to check

Returns:

the corresponding ActivationSpec class, or null if not determinable

See Also:

setActivationSpecClass(java.lang.Class<?>)

populateActivationSpecProperties

protected void populateActivationSpecProperties(BeanWrapper bw,
                                                JmsActivationSpecConfig config)

Populate the given ApplicationSpec object with the settings defined in the given configuration object.

This implementation applies all standard JMS settings, but ignores "maxConcurrency" and "prefetchSize" - not supported in standard JCA 1.5.

Parameters:

bw - the BeanWrapper wrapping the ActivationSpec object

config - the configured object holding common JMS settings

applyAcknowledgeMode

protected void applyAcknowledgeMode(BeanWrapper bw,
                                    int ackMode)

Apply the specified acknowledge mode to the ActivationSpec object.

This implementation applies the standard JCA 1.5 acknowledge modes "Auto-acknowledge" and "Dups-ok-acknowledge". It throws an exception in case of CLIENT_ACKNOWLEDGE or SESSION_TRANSACTED having been requested.

Parameters:

bw - the BeanWrapper wrapping the ActivationSpec object

ackMode - the configured acknowledge mode (according to the constants in Session
