java.lang.Object org.springframework.jms.connection.TransactionAwareConnectionFactoryProxy
public class TransactionAwareConnectionFactoryProxy
Proxy for a target JMS ConnectionFactory
, adding awareness of
Spring-managed transactions. Similar to a transactional JNDI ConnectionFactory
as provided by a J2EE server.
Messaging code that should remain unaware of Spring's JMS support can work
with this proxy to seamlessly participate in Spring-managed transactions.
Note that the transaction manager, for example JmsTransactionManager
,
still needs to work with the underlying ConnectionFactory, not with
this proxy.
Make sure that TransactionAwareConnectionFactoryProxy is the outermost
ConnectionFactory of a chain of ConnectionFactory proxies/adapters.
TransactionAwareConnectionFactoryProxy can delegate either directly to the
target factory or to some intermediary adapter like
UserCredentialsConnectionFactoryAdapter
.
Delegates to ConnectionFactoryUtils
for automatically participating
in thread-bound transactions, for example managed by JmsTransactionManager
.
createSession
calls and close
calls on returned Sessions
will behave properly within a transaction, that is, always work on the transactional
Session. If not within a transaction, normal ConnectionFactory behavior applies.
Note that transactional JMS Sessions will be registered on a per-Connection
basis. To share the same JMS Session across a transaction, make sure that you
operate on the same JMS Connection handle - either through reusing the handle
or through configuring a SingleConnectionFactory
underneath.
Returned transactional Session proxies will implement the SessionProxy
interface to allow for access to the underlying target Session. This is only
intended for accessing vendor-specific Session API or for testing purposes
(e.g. to perform manual transaction control). For typical application purposes,
simply use the standard JMS Session interface.

void |
setSynchedLocalTransactionAllowed(boolean synchedLocalTransactionAllowed)
Set 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. |

public final void setTargetConnectionFactory(ConnectionFactory targetConnectionFactory)
protected ConnectionFactory getTargetConnectionFactory()
public void setSynchedLocalTransactionAllowed(boolean synchedLocalTransactionAllowed)
Default is "false": If not within a managed transaction that encompasses the underlying JMS ConnectionFactory, standard Sessions will be returned. Turn this flag on to allow participation in any Spring-managed transaction, with a local JMS transaction synchronized with the main transaction.
