public class CTPTransactionManager
extends CtpAbstractPlatformTransactionManager
implements org.springframework.transaction.support.ResourceTransactionManager, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.InitializingBean

PlatformTransactionManager implementation for a single Hibernate SessionFactory. Binds a Hibernate Session from the specified factory to the thread, potentially allowing for one thread-bound Session per factory. SessionFactoryUtils and HibernateTemplate are aware of thread-bound Sessions and participate in such transactions automatically. Using either of those or going through SessionFactory.getCurrentSession() is required for Hibernate access code that needs to support this transaction handling mechanism.

Supports custom isolation levels, and timeouts that get applied as Hibernate transaction timeouts.

This transaction manager is appropriate for applications that use a single Hibernate SessionFactory for transactional data access, but it also supports direct DataSource access within a transaction (i.e. plain JDBC code working with the same DataSource). This allows for mixing services which access Hibernate and services which use plain JDBC (without being aware of Hibernate)! Application code needs to stick to the same simple Connection lookup pattern as with DataSourceTransactionManager (i.e. DataSourceUtils.getConnection(javax.sql.DataSource) or going through a TransactionAwareDataSourceProxy).

Note: To be able to register a DataSource's Connection for plain JDBC code, this instance needs to be aware of the DataSource (setDataSource(javax.sql.DataSource)). The given DataSource should obviously match the one used by the given SessionFactory. To achieve this, configure both to the same JNDI DataSource, or preferably create the SessionFactory with LocalSessionFactoryBean and a local DataSource (which will be autodetected by this transaction manager).

JTA (usually through JtaTransactionManager) is necessary for accessing multiple transactional resources within the same transaction. The DataSource that Hibernate uses needs to be JTA-enabled in such a scenario (see container setup). Normally, JTA setup for Hibernate is somewhat container-specific due to the JTA TransactionManager lookup, required for proper transactional handling of the SessionFactory-level read-write cache.

Fortunately, there is an easier way with Spring: SessionFactoryUtils (and thus HibernateTemplate) registers synchronizations with Spring's TransactionSynchronizationManager (as used by JtaTransactionManager), for proper after-completion callbacks. Therefore, as long as Spring's JtaTransactionManager drives the JTA transactions, Hibernate does not require any special configuration for proper JTA participation. Note that there are special restrictions with EJB CMT and restrictive JTA subsystems: See JtaTransactionManager's javadoc for details.

On JDBC 3.0, this transaction manager supports nested transactions via JDBC 3.0 Savepoints. The CtpAbstractPlatformTransactionManager.setNestedTransactionAllowed(boolean) "nestedTransactionAllowed"} flag defaults to "false", though, as nested transactions will just apply to the JDBC Connection, not to the Hibernate Session and its cached objects. You can manually set the flag to "true" if you want to use nested transactions for JDBC access code which participates in Hibernate transactions (provided that your JDBC driver supports Savepoints). Note that Hibernate itself does not support nested transactions! Hence, do not expect Hibernate access code to semantically participate in a nested transaction.

Requires Hibernate 3.1 or later, as of Spring 2.5.

构造器详细资料

CTPTransactionManager

public CTPTransactionManager()

Create a new HibernateTransactionManager instance. A SessionFactory has to be set to be able to use it.

另请参阅:

setSessionFactory(org.hibernate.SessionFactory)

CTPTransactionManager

public CTPTransactionManager(org.hibernate.SessionFactory sessionFactory)

Create a new HibernateTransactionManager instance.

参数:

sessionFactory - SessionFactory to manage transactions for

方法详细资料

setSessionFactory

public void setSessionFactory(org.hibernate.SessionFactory sessionFactory)

Set the SessionFactory that this instance should manage transactions for.

getSessionFactory

public org.hibernate.SessionFactory getSessionFactory()

Return the SessionFactory that this instance should manage transactions for.

setDataSource

public void setDataSource(javax.sql.DataSource dataSource)

Set the JDBC DataSource that this instance should manage transactions for. The DataSource should match the one used by the Hibernate SessionFactory: for example, you could specify the same JNDI DataSource for both.

If the SessionFactory was configured with LocalDataSourceConnectionProvider, i.e. by Spring's LocalSessionFactoryBean with a specified "dataSource", the DataSource will be auto-detected: You can still explictly specify the DataSource, but you don't need to in this case.

A transactional JDBC Connection for this DataSource will be provided to application code accessing this DataSource directly via DataSourceUtils or JdbcTemplate. The Connection will be taken from the Hibernate Session.

The DataSource specified here should be the target DataSource to manage transactions for, not a TransactionAwareDataSourceProxy. Only data access code may work with TransactionAwareDataSourceProxy, while the transaction manager needs to work on the underlying target DataSource. If there's nevertheless a TransactionAwareDataSourceProxy passed in, it will be unwrapped to extract its target DataSource.

另请参阅:

setAutodetectDataSource(boolean), LocalDataSourceConnectionProvider, AbstractSessionFactoryBean.setDataSource(javax.sql.DataSource), TransactionAwareDataSourceProxy, DataSourceUtils, JdbcTemplate

getDataSource

public javax.sql.DataSource getDataSource()

Return the JDBC DataSource that this instance manages transactions for.

setAutodetectDataSource

public void setAutodetectDataSource(boolean autodetectDataSource)

Set whether to autodetect a JDBC DataSource used by the Hibernate SessionFactory, if set via LocalSessionFactoryBean's setDataSource. Default is "true".

Can be turned off to deliberately ignore an available DataSource, in order to not expose Hibernate transactions as JDBC transactions for that DataSource.

另请参阅:

setDataSource(javax.sql.DataSource), AbstractSessionFactoryBean.setDataSource(javax.sql.DataSource)

setPrepareConnection

public void setPrepareConnection(boolean prepareConnection)

Set whether to prepare the underlying JDBC Connection of a transactional Hibernate Session, that is, whether to apply a transaction-specific isolation level and/or the transaction's read-only flag to the underlying JDBC Connection.

Default is "true". If you turn this flag off, the transaction manager will not support per-transaction isolation levels anymore. It will not call Connection.setReadOnly(true) for read-only transactions anymore either. If this flag is turned off, no cleanup of a JDBC Connection is required after a transaction, since no Connection settings will get modified.

It is recommended to turn this flag off if running against Hibernate 3.1 and a connection pool that does not reset connection settings (for example, Jakarta Commons DBCP). To keep this flag turned on, you can set the "hibernate.connection.release_mode" property to "on_close" instead, or consider using a smarter connection pool (for example, C3P0).

另请参阅:

Connection.setTransactionIsolation(int), Connection.setReadOnly(boolean)

setHibernateManagedSession

public void setHibernateManagedSession(boolean hibernateManagedSession)

Set whether to operate on a Hibernate-managed Session instead of a Spring-managed Session, that is, whether to obtain the Session through Hibernate's SessionFactory.getCurrentSession() instead of SessionFactory.openSession() (with a Spring TransactionSynchronizationManager check preceding it).

Default is "false", i.e. using a Spring-managed Session: taking the current thread-bound Session if available (e.g. in an Open-Session-in-View scenario), creating a new Session for the current transaction otherwise.

Switch this flag to "true" in order to enforce use of a Hibernate-managed Session. Note that this requires SessionFactory.getCurrentSession() to always return a proper Session when called for a Spring-managed transaction; transaction begin will fail if the getCurrentSession() call fails.

This mode will typically be used in combination with a custom Hibernate CurrentSessionContext implementation that stores Sessions in a place other than Spring's TransactionSynchronizationManager. It may also be used in combination with Spring's Open-Session-in-View support (using Spring's default SpringSessionContext), in which case it subtly differs from the Spring-managed Session mode: The pre-bound Session will not receive a clear() call (on rollback) or a disconnect() call (on transaction completion) in such a scenario; this is rather left up to a custom CurrentSessionContext implementation (if desired).

setEarlyFlushBeforeCommit

public void setEarlyFlushBeforeCommit(boolean earlyFlushBeforeCommit)

Set whether to perform an early flush before proceeding with a commit.

Default is "false", performing an implicit flush as part of the actual commit step. Switch this to "true" in order to enforce an explicit early flush right before the actual commit step.

An early flush happens before the before-commit synchronization phase, making flushed state visible to beforeCommit callbacks of registered TransactionSynchronization objects. Such explicit flush behavior is consistent with Spring-driven flushing in a JTA transaction environment, so may also get enforced for consistency with JTA transaction behavior.

setEntityInterceptorBeanName

public void setEntityInterceptorBeanName(java.lang.String entityInterceptorBeanName)

Set the bean name of a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this transaction manager.

Requires the bean factory to be known, to be able to resolve the bean name to an interceptor instance on session creation. Typically used for prototype interceptors, i.e. a new interceptor instance per session.

Can also be used for shared interceptor instances, but it is recommended to set the interceptor reference directly in such a scenario.

参数:

entityInterceptorBeanName - the name of the entity interceptor in the bean factory

另请参阅:

setBeanFactory(org.springframework.beans.factory.BeanFactory), setEntityInterceptor(org.hibernate.Interceptor)

setEntityInterceptor

public void setEntityInterceptor(org.hibernate.Interceptor entityInterceptor)

Set a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this transaction manager.

Such an interceptor can either be set at the SessionFactory level, i.e. on LocalSessionFactoryBean, or at the Session level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryBean or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions.

                                               throws java.lang.IllegalStateException,
                                                      org.springframework.beans.BeansException

Return the current Hibernate entity interceptor, or null if none. Resolves an entity interceptor bean name via the bean factory, if necessary.

抛出:

java.lang.IllegalStateException - if bean name specified but no bean factory set

org.springframework.beans.BeansException - if bean name resolution via the bean factory failed

setJdbcExceptionTranslator

public void setJdbcExceptionTranslator(org.springframework.jdbc.support.SQLExceptionTranslator jdbcExceptionTranslator)

Set the JDBC exception translator for this transaction manager.

Applied to any SQLException root cause of a Hibernate JDBCException that is thrown on flush, overriding Hibernate's default SQLException translation (which is based on Hibernate's Dialect for a specific target database).

参数:

jdbcExceptionTranslator - the exception translator

getJdbcExceptionTranslator

public org.springframework.jdbc.support.SQLExceptionTranslator getJdbcExceptionTranslator()

Return the JDBC exception translator for this transaction manager, if any.

doGetTransaction

protected java.lang.Object doGetTransaction()

从类复制的说明: CtpAbstractPlatformTransactionManager

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, a doGetTransaction implementation will usually look for an existing transaction and store corresponding state in the returned transaction object.

指定者:

doGetTransaction 在类中 CtpAbstractPlatformTransactionManager

返回:

the current transaction object

另请参阅:

isExistingTransaction

protected boolean isExistingTransaction(java.lang.Object transaction)

从类复制的说明: CtpAbstractPlatformTransactionManager

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 CtpAbstractPlatformTransactionManager

参数:

transaction - transaction object returned by doGetTransaction

返回:

if there is an existing transaction

doBegin

protected void doBegin(java.lang.Object transaction,
                       org.springframework.transaction.TransactionDefinition definition)

从类复制的说明: CtpAbstractPlatformTransactionManager

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 CtpAbstractPlatformTransactionManager

参数:

transaction - transaction object returned by doGetTransaction

definition - TransactionDefinition instance, describing propagation behavior, isolation level, read-only flag, timeout, and transaction name

doSuspend

protected java.lang.Object doSuspend(java.lang.Object transaction)

从类复制的说明: CtpAbstractPlatformTransactionManager

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 CtpAbstractPlatformTransactionManager

参数:

transaction - transaction object returned by doGetTransaction

返回:

an object that holds suspended resources (will be kept unexamined for passing it into doResume)

从类复制的说明: CtpAbstractPlatformTransactionManager

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 CtpAbstractPlatformTransactionManager

参数:

transaction - transaction object returned by doGetTransaction

suspendedResources - the object that holds suspended resources, as returned by doSuspend

prepareForCommit

protected void prepareForCommit(org.springframework.transaction.support.DefaultTransactionStatus status)

从类复制的说明: CtpAbstractPlatformTransactionManager

Make preparations for commit, to be performed before the beforeCommit synchronization callbacks occur.

Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.

覆盖:

prepareForCommit 在类中 CtpAbstractPlatformTransactionManager

参数:

status - the status representation of the transaction

doCommit

protected void doCommit(org.springframework.transaction.support.DefaultTransactionStatus status)

从类复制的说明: CtpAbstractPlatformTransactionManager

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.

doSetRollbackOnly

protected void doSetRollbackOnly(org.springframework.transaction.support.DefaultTransactionStatus status)

从类复制的说明: CtpAbstractPlatformTransactionManager

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.

参数:

transaction - transaction object returned by doGetTransaction

isSameConnectionForEntireSession

protected boolean isSameConnectionForEntireSession(org.hibernate.Session session)

Return whether the given Hibernate Session will always hold the same JDBC Connection. This is used to check whether the transaction manager can safely prepare and clean up the JDBC Connection used for a transaction.

Default implementation checks the Session's connection release mode to be "on_close". Unfortunately, this requires casting to SessionImpl, as of Hibernate 3.1. If that cast doesn't work, we'll simply assume we're safe and return true.

参数:

session - the Hibernate Session to check

另请参阅:

Will automatically apply a specified SQLExceptionTranslator to a Hibernate JDBCException, else rely on Hibernate's default translation.

参数:

ex - HibernateException that occured

返回:
