org.springframework.jms.support
Class JmsAccessor

java.lang.Object
  org.springframework.jms.support.JmsAccessor

Direct Known Subclasses:: JmsDestinationAccessor

public abstract class JmsAccessor

Base class for JmsTemplate and other JMS-accessing gateway helpers, defining common properties such as the JMS ConnectionFactory to operate on. The subclass JmsDestinationAccessor adds further, destination-related properties.

Not intended to be used directly. See JmsTemplate.

Since:: 1.2
Author:: Juergen Hoeller
See Also:: JmsDestinationAccessor, JmsTemplate

Field Detail

logger

protected final Log logger

Logger available to subclasses

Constructor Detail

JmsAccessor

public JmsAccessor()

Method Detail

setConnectionFactory

public void setConnectionFactory(ConnectionFactory connectionFactory)

Set the ConnectionFactory to use for obtaining JMS Connections.

getConnectionFactory

public ConnectionFactory getConnectionFactory()

Return the ConnectionFactory that this accessor uses for obtaining JMS Connections.

setSessionTransacted

public void setSessionTransacted(boolean sessionTransacted)

Set the transaction mode that is used when creating a JMS Session. Default is "false".

Note that within a JTA transaction, the parameters passed to create(Queue/Topic)Session(boolean transacted, int acknowledgeMode) method are not taken into account. Depending on the J2EE transaction context, the container makes its own decisions on these values. Analogously, these parameters are not taken into account within a locally managed transaction either, since the accessor operates on an existing JMS Session in this case.

Setting this flag to "true" will use a short local JMS transaction when running outside of a managed transaction, and a synchronized local JMS transaction in case of a managed transaction (other than an XA transaction) being present. The latter has the effect of a local JMS transaction being managed alongside the main transaction (which might be a native JDBC transaction), with the JMS transaction committing right after the main transaction.

Parameters:: sessionTransacted - the transaction mode
See Also:: Connection.createSession(boolean, int)

isSessionTransacted

public boolean isSessionTransacted()

Return whether the JMS sessions used by this accessor are supposed to be transacted.

Returns:: true if the JMS Sessions used are transacted
See Also:: setSessionTransacted(boolean)

setSessionAcknowledgeModeName

public void setSessionAcknowledgeModeName(String constantName)

Set the JMS acknowledgement mode by the name of the corresponding constant in the JMS Session interface, e.g. "CLIENT_ACKNOWLEDGE".

If you want to use vendor-specific extensions to the acknowledgment mode, use setSessionAcknowledgeModeName(String) instead.

Parameters:: constantName - the name of the Session acknowledge mode constant
See Also:: Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, Session.DUPS_OK_ACKNOWLEDGE, Connection.createSession(boolean, int)

setSessionAcknowledgeMode

public void setSessionAcknowledgeMode(int sessionAcknowledgeMode)

Set the JMS acknowledgement mode that is used when creating a JMS Session to send a message.

Default is Session.AUTO_ACKNOWLEDGE.

Vendor-specific extensions to the acknowledgment mode can be set here as well.

Note that that inside an EJB the parameters to create(Queue/Topic)Session(boolean transacted, int acknowledgeMode) method are not taken into account. Depending on the transaction context in the EJB, the container makes its own decisions on these values. See section 17.3.5 of the EJB spec.

Parameters:: sessionAcknowledgeMode - the acknowledgement mode
See Also:: Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, Session.DUPS_OK_ACKNOWLEDGE, Connection.createSession(boolean, int)

getSessionAcknowledgeMode

public int getSessionAcknowledgeMode()

Return the acknowledgement mode for JMS sessions.

Returns:: the acknowledgement mode applied by this accessor

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:: afterPropertiesSet in interface InitializingBean

convertJmsAccessException

protected JmsException convertJmsAccessException(JMSException ex)

Convert the specified checked JMSException to a Spring runtime JmsException equivalent.

The default implementation delegates to the JmsUtils.convertJmsAccessException(javax.jms.JMSException) method.

Parameters:: ex - the original checked JMSException to convert
Returns:: the Spring runtime JmsException wrapping ex
See Also:: JmsUtils.convertJmsAccessException(javax.jms.JMSException)

createConnection

protected Connection createConnection()
                               throws JMSException

Create a JMS Connection via this template's ConnectionFactory.

This implementation uses JMS 1.1 API.

Returns:: the new JMS Connection
Throws:: JMSException - if thrown by JMS API methods
See Also:: ConnectionFactory.createConnection()

createSession

protected Session createSession(Connection con)
                         throws JMSException

Create a JMS Session for the given Connection.

This implementation uses JMS 1.1 API.

Parameters:: con - the JMS Connection to create a Session for
Returns:: the new JMS Session
Throws:: JMSException - if thrown by JMS API methods
See Also:: Connection.createSession(boolean, int)

isClientAcknowledge

protected boolean isClientAcknowledge(Session session)
                               throws JMSException

Determine whether the given Session is in client acknowledge mode.

This implementation uses JMS 1.1 API.

Parameters:: session - the JMS Session to check
Returns:: whether the given Session is in client acknowledge mode
Throws:: JMSException - if thrown by JMS API methods
See Also:: Session.getAcknowledgeMode(), Session.CLIENT_ACKNOWLEDGE
