Method Detail
releaseConnection
public static void releaseConnection(Connection con, ConnectionFactory cf, boolean started)
Release the given Connection, stopping it (if necessary) and eventually closing it.Checks
SmartConnectionFactory.shouldStop(javax.jms.Connection), if available. This is essentially a more sophisticated version ofJmsUtils.closeConnection(javax.jms.Connection).- Parameters:
con- the Connection to release (if this isnull, the call will be ignored)cf- the ConnectionFactory that the Connection was obtained from (may benull)started- whether the Connection might have been started by the application- See Also:
SmartConnectionFactory.shouldStop(javax.jms.Connection),JmsUtils.closeConnection(javax.jms.Connection)
getTargetSession
public static Session getTargetSession(Session session)
Return the innermost target Session of the given Session. If the given Session is a proxy, it will be unwrapped until a non-proxy Session is found. Otherwise, the passed-in Session will be returned as-is.- Parameters:
session- the Session proxy to unwrap- Returns:
- the innermost target Session, or the passed-in one if no proxy
- See Also:
SessionProxy.getTargetSession()
isSessionTransactional
public static boolean isSessionTransactional(Session session, ConnectionFactory cf)
Determine whether the given JMS Session is transactional, that is, bound to the current thread by Spring's transaction facilities.- Parameters:
session- the JMS Session to checkcf- the JMS ConnectionFactory that the Session originated from- Returns:
- whether the Session is transactional
getTransactionalSession
public static Session getTransactionalSession(ConnectionFactory cf, Connection existingCon, boolean synchedLocalTransactionAllowed) throws JMSException
Obtain a JMS Session that is synchronized with the current transaction, if any.- Parameters:
cf- the ConnectionFactory to obtain a Session forexistingCon- the existing JMS Connection to obtain a Session for (may benull)synchedLocalTransactionAllowed- whether to allow for a local JMS transaction that is synchronized with a Spring-managed transaction (where the main transaction might be a JDBC-based one for a specific DataSource, for example), with the JMS transaction committing right after the main transaction. If not allowed, the given ConnectionFactory needs to handle transaction enlistment underneath the covers.- Returns:
- the transactional Session, or
nullif none found - Throws:
JMSException- in case of JMS failure
getTransactionalQueueSession
public static QueueSession getTransactionalQueueSession(QueueConnectionFactory cf, QueueConnection existingCon, boolean synchedLocalTransactionAllowed) throws JMSException
Obtain a JMS QueueSession that is synchronized with the current transaction, if any.Mainly intended for use with the JMS 1.0.2 API.
- Parameters:
cf- the ConnectionFactory to obtain a Session forexistingCon- the existing JMS Connection to obtain a Session for (may benull)synchedLocalTransactionAllowed- whether to allow for a local JMS transaction that is synchronized with a Spring-managed transaction (where the main transaction might be a JDBC-based one for a specific DataSource, for example), with the JMS transaction committing right after the main transaction. If not allowed, the given ConnectionFactory needs to handle transaction enlistment underneath the covers.- Returns:
- the transactional Session, or
nullif none found - Throws:
JMSException- in case of JMS failure
getTransactionalTopicSession
public static TopicSession getTransactionalTopicSession(TopicConnectionFactory cf, TopicConnection existingCon, boolean synchedLocalTransactionAllowed) throws JMSException
Obtain a JMS TopicSession that is synchronized with the current transaction, if any.Mainly intended for use with the JMS 1.0.2 API.
- Parameters:
cf- the ConnectionFactory to obtain a Session forexistingCon- the existing JMS Connection to obtain a Session for (may benull)synchedLocalTransactionAllowed- whether to allow for a local JMS transaction that is synchronized with a Spring-managed transaction (where the main transaction might be a JDBC-based one for a specific DataSource, for example), with the JMS transaction committing right after the main transaction. If not allowed, the given ConnectionFactory needs to handle transaction enlistment underneath the covers.- Returns:
- the transactional Session, or
nullif none found - Throws:
JMSException- in case of JMS failure
doGetTransactionalSession
public static Session doGetTransactionalSession(ConnectionFactory connectionFactory, ConnectionFactoryUtils.ResourceFactory resourceFactory) throws JMSException
Obtain a JMS Session that is synchronized with the current transaction, if any.This
doGetTransactionalSessionvariant always starts the underlying JMS Connection, assuming that the Session will be used for receiving messages.- Parameters:
connectionFactory- the JMS ConnectionFactory to bind for (used as TransactionSynchronizationManager key)resourceFactory- the ResourceFactory to use for extracting or creating JMS resources- Returns:
- the transactional Session, or
nullif none found - Throws:
JMSException- in case of JMS failure- See Also:
doGetTransactionalSession(javax.jms.ConnectionFactory, ResourceFactory, boolean)
doGetTransactionalSession
public static Session doGetTransactionalSession(ConnectionFactory connectionFactory, ConnectionFactoryUtils.ResourceFactory resourceFactory, boolean startConnection) throws JMSException
Obtain a JMS Session that is synchronized with the current transaction, if any.- Parameters:
connectionFactory- the JMS ConnectionFactory to bind for (used as TransactionSynchronizationManager key)resourceFactory- the ResourceFactory to use for extracting or creating JMS resourcesstartConnection- whether the underlying JMS Connection approach should be started in order to allow for receiving messages. Note that a reused Connection may already have been started before, even if this flag isfalse.- Returns:
- the transactional Session, or
nullif none found - Throws:
JMSException- in case of JMS failure
