## 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.

`protected void` `populateActivationSpecProperties(BeanWrapper bw, JmsActivationSpecConfig config)` Populate the given ApplicationSpec object with the settings defined in the given configuration object.
`void` `setActivationSpecClass(Class activationSpecClass)` Specify the fully-qualified ActivationSpec class name for the target provider (e.g.
`void` `setDefaultProperties(Map<String,String> defaultProperties)` Specify custom default properties, with String keys and String values.
`void` `setDestinationResolver(DestinationResolver destinationResolver)` Set the DestinationResolver to use for resolving destination names into the JCA 1.5 ActivationSpec "destination" property.

### Constructor Detail

#### 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`.

#### 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`
