public class TransactionAwareConnectionFactoryProxy extends Object implements ConnectionFactory, QueueConnectionFactory, TopicConnectionFactory
ConnectionFactory, adding awareness of
Spring-managed transactions. Similar to a transactional JNDI ConnectionFactory
as provided by a Java EE application server.
Messaging code which 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.
As of Spring Framework 5, this class delegates JMS 2.0 JMSContext
calls and therefore requires the JMS 2.0 API to be present at runtime.
It may nevertheless run against a JMS 1.1 driver (bound to the JMS 2.0 API)
as long as no actual JMS 2.0 calls are triggered by the application's setup.

getTargetConnectionFactory()
Return the target ConnectionFactory that this ConnectionFactory should delegate to.
|
protected Connection |
getTransactionAwareConnectionProxy(Connection target)
Wrap the given Connection with a proxy that delegates every method call to it
but handles Session lookup in a transaction-aware fashion.
|
protected boolean |
isSynchedLocalTransactionAllowed()
Return whether to allow for a local JMS transaction that is synchronized
with a Spring-managed transaction.
|
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.
|
void |
setTargetConnectionFactory(ConnectionFactory targetConnectionFactory)
Set the target ConnectionFactory that this ConnectionFactory should delegate to.

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.
