public class CciLocalTransactionManager extends AbstractPlatformTransactionManager implements ResourceTransactionManager, 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 Java EE-styleConnectionFactory.getConnection()
call. Spring classes such asCciTemplate
use this strategy implicitly. If not used in combination with this transaction manager, theConnectionFactoryUtils
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 Java EE lookup pattern
ConnectionFactory.getConnection()
, for example for legacy code that is not aware of Spring at all. In that case, define aTransactionAwareConnectionFactoryProxy
for your target ConnectionFactory, which will automatically participate in Spring-managed transactions.- 从以下版本开始:

CciLocalTransactionManager
public CciLocalTransactionManager()
Create a new CciLocalTransactionManager instance. A ConnectionFactory has to be set to be able to use it.
CciLocalTransactionManager
public CciLocalTransactionManager(ConnectionFactory connectionFactory)
Create a new CciLocalTransactionManager instance.- 参数:
connectionFactory
- CCI ConnectionFactory to manage local transactions for
方法详细资料
setConnectionFactory
public void setConnectionFactory(ConnectionFactory cf)
Set the CCI ConnectionFactory that this instance should manage local transactions for.
getConnectionFactory
public ConnectionFactory getConnectionFactory()
Return the CCI ConnectionFactory that this instance manages local transactions for.
afterPropertiesSet
public void afterPropertiesSet()
从接口复制的说明:InitializingBean
Invoked by the containingBeanFactory
after it has set all bean properties and satisfiedBeanFactoryAware
,ApplicationContextAware
etc.This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
- 指定者:
afterPropertiesSet
在接口中InitializingBean
getResourceFactory
public Object getResourceFactory()
从接口复制的说明:ResourceTransactionManager
Return the resource factory that this transaction manager operates on, e.g. a JDBC DataSource or a JMS ConnectionFactory.This target resource factory is usually used as resource key for
TransactionSynchronizationManager
's resource bindings per thread.- 指定者:
getResourceFactory
在接口中ResourceTransactionManager
- 返回:
- the target resource factory (never
null
) - 另请参阅:
TransactionSynchronizationManager.bindResource(java.lang.Object, java.lang.Object)
,TransactionSynchronizationManager.getResource(java.lang.Object)
doGetTransaction
protected Object doGetTransaction()
从类复制的说明:AbstractPlatformTransactionManager
Return a transaction object for the current transaction state.The 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, adoGetTransaction
implementation will usually look for an existing transaction and store corresponding state in the returned transaction object.- 指定者:
doGetTransaction
在类中AbstractPlatformTransactionManager
- 返回:
- the current transaction object
- 另请参阅:
AbstractPlatformTransactionManager.doBegin(java.lang.Object, org.springframework.transaction.TransactionDefinition)
,AbstractPlatformTransactionManager.doCommit(org.springframework.transaction.support.DefaultTransactionStatus)

,DefaultTransactionStatus.getTransaction()
isExistingTransaction
protected boolean isExistingTransaction(Object transaction)
从类复制的说明:AbstractPlatformTransactionManager
Check if the given transaction object indicates an existing transaction (that is, a transaction which has already started).The 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.- 覆盖:
isExistingTransaction
在类中AbstractPlatformTransactionManager
- 参数:
transaction
- transaction object returned by doGetTransaction- 返回:
- if there is an existing transaction
- 另请参阅:
AbstractPlatformTransactionManager.doGetTransaction()
doBegin
protected void doBegin(Object transaction, TransactionDefinition definition)
从类复制的说明:AbstractPlatformTransactionManager
Begin a new transaction with semantics according to the given transaction definition. Does not have to care about applying the propagation behavior, as this has already been handled by this abstract manager.This 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.- 指定者:
doBegin
在类中AbstractPlatformTransactionManager
- 参数:
transaction
- transaction object returned bydoGetTransaction
definition
- TransactionDefinition instance, describing propagation behavior, isolation level, read-only flag, timeout, and transaction name
doSuspend
protected Object doSuspend(Object transaction)
从类复制的说明:AbstractPlatformTransactionManager
Suspend the resources of the current transaction. Transaction synchronization will already have been suspended.The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.
- 覆盖:
doSuspend
在类中AbstractPlatformTransactionManager
- 参数:
transaction
- transaction object returned bydoGetTransaction
- 返回:
- an object that holds suspended resources (will be kept unexamined for passing it into doResume)
- 另请参阅:
AbstractPlatformTransactionManager.doResume(java.lang.Object, java.lang.Object)
doResume
protected void doResume(Object transaction, Object suspendedResources)
从类复制的说明:AbstractPlatformTransactionManager
Resume the resources of the current transaction. Transaction synchronization will be resumed afterwards.The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.
- 覆盖:
doResume
在类中AbstractPlatformTransactionManager
- 参数:
transaction
- transaction object returned bydoGetTransaction
suspendedResources
- the object that holds suspended resources, as returned by doSuspend- 另请参阅:

isRollbackOnly
protected boolean isRollbackOnly(Object transaction) throws TransactionException
doCommit
protected void doCommit(DefaultTransactionStatus status)
从类复制的说明:AbstractPlatformTransactionManager
Perform an actual commit of the given transaction.An 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.
- 指定者:
doCommit
在类中AbstractPlatformTransactionManager
- 参数:
status
- the status representation of the transaction- 另请参阅:
DefaultTransactionStatus.getTransaction()
doRollback
protected void doRollback(DefaultTransactionStatus status)
从类复制的说明:AbstractPlatformTransactionManager

status
- the status representation of the transaction- 另请参阅:
DefaultTransactionStatus.getTransaction()
doSetRollbackOnly
protected void doSetRollbackOnly(DefaultTransactionStatus status)
从类复制的说明:AbstractPlatformTransactionManager
Set the given transaction rollback-only. Only called on rollback if the current transaction participates in an existing one.The default implementation throws an IllegalTransactionStateException, assuming that participating in existing transactions is generally not supported. Subclasses are of course encouraged to provide such support.
