public class CciLocalTransactionManager extends AbstractPlatformTransactionManager implements ResourceTransactionManager, org.springframework.beans.factory.InitializingBean
PlatformTransactionManager implementation
that manages local transactions for a single CCI ConnectionFactory.
Binds a CCI Connection from the specified ConnectionFactory to the thread,
potentially allowing for one thread-bound Connection per ConnectionFactory.
Application code is required to retrieve the CCI Connection via
ConnectionFactoryUtils.getConnection(ConnectionFactory) instead of a standard
J2EE-style ConnectionFactory.getConnection() call. Spring classes such as
CciTemplate use this strategy implicitly.
If not used in combination with this transaction manager, the
ConnectionFactoryUtils lookup strategy behaves exactly like the native
DataSource lookup; it can thus be used in a portable fashion.
Alternatively, you can allow application code to work with the standard
J2EE lookup pattern ConnectionFactory.getConnection(), for example
for legacy code that is not aware of Spring at all. In that case, define a
TransactionAwareConnectionFactoryProxy for your target ConnectionFactory,
which will automatically participate in Spring-managed transactions.

ResourceTransactionManagerThis target resource factory is usually used as resource key for
TransactionSynchronizationManager's resource bindings per thread.

AbstractPlatformTransactionManagerThe returned object will usually be specific to the concrete transaction manager implementation, carrying corresponding transaction state in a modifiable fashion. This object will be passed into the other template methods (e.g. doBegin and doCommit), either directly or as part of a DefaultTransactionStatus instance.
The returned object should contain information about any existing
transaction, that is, a transaction that has already started before the
current getTransaction call on the transaction manager.
Consequently, a doGetTransaction implementation will usually
look for an existing transaction and store corresponding state in the
returned transaction object.

AbstractPlatformTransactionManagerThe result will be evaluated according to the specified propagation behavior for the new transaction. An existing transaction might get suspended (in case of PROPAGATION_REQUIRES_NEW), or the new transaction might participate in the existing one (in case of PROPAGATION_REQUIRED).
The default implementation returns false, assuming that
participating in existing transactions is generally not supported.
Subclasses are of course encouraged to provide such support.
isExistingTransaction in class AbstractPlatformTransactionManagertransaction - transaction object returned by doGetTransactionAbstractPlatformTransactionManager.doGetTransaction()protected void doBegin(Object transaction, TransactionDefinition definition)
AbstractPlatformTransactionManagerThis method gets called when the transaction manager has decided to actually start a new transaction. Either there wasn't any transaction before, or the previous transaction has been suspended.
A special scenario is a nested transaction without savepoint: If
useSavepointForNestedTransaction() returns "false", this method
will be called to start a nested transaction when necessary. In such a context,
there will be an active transaction: The implementation of this method has
to detect this and start an appropriate nested transaction.

AbstractPlatformTransactionManagerThe default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.

AbstractPlatformTransactionManagerAn implementation does not need to check the "new transaction" flag or the rollback-only flag; this will already have been handled before. Usually, a straight commit will be performed on the transaction object contained in the passed-in status.
