org.springframework.orm.hibernate3.SessionFactoryUtils

Deprecated.

as of Spring 4.3, in favor of Hibernate 4.x/5.x

@Deprecated
public abstract class SessionFactoryUtils
extends java.lang.Object

Helper class featuring methods for Hibernate Session handling, allowing for reuse of Hibernate Session instances within transactions. Also provides support for exception translation.

Supports synchronization with both Spring-managed JTA transactions (see JtaTransactionManager) and non-Spring JTA transactions (i.e. plain JTA or EJB CMT), transparently providing transaction-scoped Hibernate Sessions. Note that for non-Spring JTA transactions, a JTA TransactionManagerLookup has to be specified in the Hibernate configuration.

Used internally by HibernateTemplate, HibernateInterceptor and HibernateTransactionManager. Can also be used directly in application code.

Requires Hibernate 3.6.x, as of Spring 4.0.

Since:

1.2

Returns:

the DataSource, or null if none found

See Also:

SessionFactoryImplementor.getConnectionProvider(), LocalDataSourceConnectionProvider

newJdbcExceptionTranslator

public static SQLExceptionTranslator newJdbcExceptionTranslator(SessionFactory sessionFactory)

getJtaTransactionManager

public static TransactionManager getJtaTransactionManager(SessionFactory sessionFactory,
                                                          Session session)

Deprecated.

Try to retrieve the JTA TransactionManager from the given SessionFactory and/or Session. Check the passed-in SessionFactory for implementing SessionFactoryImplementor (the usual case), falling back to the SessionFactory reference that the Session itself carries.

Parameters:

sessionFactory - Hibernate SessionFactory

session - Hibernate Session (can also be null)

Returns:

the JTA TransactionManager, if any

See Also:

TransactionManager, SessionFactoryImplementor.getTransactionManager(), Session.getSessionFactory(), SessionFactoryImpl

getSession

public static Session getSession(SessionFactory sessionFactory,
                                 boolean allowCreate)
                          throws DataAccessResourceFailureException,
                                 java.lang.IllegalStateException

Deprecated.

Get a Hibernate Session for the given SessionFactory. Is aware of and will return any existing corresponding Session bound to the current thread, for example when using HibernateTransactionManager. Will create a new Session otherwise, if "allowCreate" is true.

This is the getSession method used by typical data access code, in combination with releaseSession called when done with the Session. Note that HibernateTemplate allows to write data access code without caring about such resource handling.

Parameters:

sessionFactory - Hibernate SessionFactory to create the session with

allowCreate - whether a non-transactional Session should be created when no transactional Session can be found for the current thread

Returns:

the Hibernate Session

Throws:

DataAccessResourceFailureException - if the Session couldn't be created

java.lang.IllegalStateException - if no thread-bound Session found and "allowCreate" is false

See Also:

getSession(SessionFactory, Interceptor, SQLExceptionTranslator), releaseSession(org.hibernate.Session, org.hibernate.SessionFactory), HibernateTemplate

getSession

public static Session getSession(SessionFactory sessionFactory,
                                 Interceptor entityInterceptor,
                                 SQLExceptionTranslator jdbcExceptionTranslator)
                          throws DataAccessResourceFailureException

Deprecated.

Get a Hibernate Session for the given SessionFactory. Is aware of and will return any existing corresponding Session bound to the current thread, for example when using HibernateTransactionManager. Will always create a new Session otherwise.

Supports setting a Session-level Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Such an interceptor can also be set at the SessionFactory level (i.e. on LocalSessionFactoryBean), on HibernateTransactionManager, etc.

Parameters:

sessionFactory - Hibernate SessionFactory to create the session with

entityInterceptor - Hibernate entity interceptor, or null if none

jdbcExceptionTranslator - SQLExcepionTranslator to use for flushing the Session on transaction synchronization (may be null; only used when actually registering a transaction synchronization)

Returns:

the Hibernate Session

Throws:

DataAccessResourceFailureException - if the Session couldn't be created

See Also:

LocalSessionFactoryBean.setEntityInterceptor(org.hibernate.Interceptor), HibernateAccessor.setEntityInterceptor(org.hibernate.Interceptor)

doGetSession

public static Session doGetSession(SessionFactory sessionFactory,
                                   boolean allowCreate)
                            throws HibernateException,
                                   java.lang.IllegalStateException

Deprecated.

Get a Hibernate Session for the given SessionFactory. Is aware of and will return any existing corresponding Session bound to the current thread, for example when using HibernateTransactionManager. Will create a new Session otherwise, if "allowCreate" is true.

Throws the original HibernateException, in contrast to getSession(org.hibernate.SessionFactory, boolean).

Parameters:

sessionFactory - Hibernate SessionFactory to create the session with

allowCreate - whether a non-transactional Session should be created when no transactional Session can be found for the current thread

Returns:

the Hibernate Session

Throws:

HibernateException - if the Session couldn't be created

java.lang.IllegalStateException - if no thread-bound Session found and allowCreate false

getNewSession

public static Session getNewSession(SessionFactory sessionFactory)

Deprecated.

Get a new Hibernate Session from the given SessionFactory. Will return a new Session even if there already is a pre-bound Session for the given SessionFactory.

Within a transaction, this method will create a new Session that shares the transaction's JDBC Connection. More specifically, it will use the same JDBC Connection as the pre-bound Hibernate Session.

Parameters:

sessionFactory - Hibernate SessionFactory to create the session with

Returns:

the new Session

getNewSession

public static Session getNewSession(SessionFactory sessionFactory,
                                    Interceptor entityInterceptor)

Deprecated.

Get a new Hibernate Session from the given SessionFactory. Will return a new Session even if there already is a pre-bound Session for the given SessionFactory.

Within a transaction, this method will create a new Session that shares the transaction's JDBC Connection. More specifically, it will use the same JDBC Connection as the pre-bound Hibernate Session.

Parameters:

sessionFactory - Hibernate SessionFactory to create the session with

entityInterceptor - Hibernate entity interceptor, or null if none

Returns:

the new Session

toString

public static java.lang.String toString(Session session)

Deprecated.

Stringify the given Session for debug logging. Returns output equivalent to Object.toString(): the fully qualified class name + "@" + the identity hash code.

The sole reason why this is necessary is because Hibernate3's Session.toString() implementation is broken (and won't be fixed): it logs the toString representation of all persistent objects in the Session, which might lead to ConcurrentModificationExceptions if the persistent objects in turn refer to the Session (for example, for lazy loading).

Parameters:

session - the Hibernate Session to stringify

Returns:

the String representation of the given Session

hasTransactionalSession

public static boolean hasTransactionalSession(SessionFactory sessionFactory)

Deprecated.

Return whether there is a transactional Hibernate Session for the current thread, that is, a Session bound to the current thread by Spring's transaction facilities.

Parameters:

sessionFactory - Hibernate SessionFactory to check (may be null)

Returns:

whether there is a transactional Session for current thread

isSessionTransactional

public static boolean isSessionTransactional(Session session,
                                             SessionFactory sessionFactory)

Deprecated.

Return whether the given Hibernate Session is transactional, that is, bound to the current thread by Spring's transaction facilities.

Parameters:

session - the Hibernate Session to check

sessionFactory - Hibernate SessionFactory that the Session was created with (may be null)

Returns:

whether the Session is transactional

applyTransactionTimeout

public static void applyTransactionTimeout(Query query,
                                           SessionFactory sessionFactory)

Deprecated.

Apply the current transaction timeout, if any, to the given Hibernate Query object.

Parameters:

query - the Hibernate Query object

sessionFactory - Hibernate SessionFactory that the Query was created for (may be null)

See Also:

Query.setTimeout(int)

public static void applyTransactionTimeout(Criteria criteria,
                                           SessionFactory sessionFactory)

Deprecated.

Apply the current transaction timeout, if any, to the given Hibernate Criteria object.

Parameters:

criteria - the Hibernate Criteria object

sessionFactory - Hibernate SessionFactory that the Criteria was created for

See Also:

Criteria.setTimeout(int)

convertHibernateAccessException

public static DataAccessException convertHibernateAccessException(HibernateException ex)

Deprecated.

Convert the given HibernateException to an appropriate exception from the org.springframework.dao hierarchy.

Parameters:

Returns:

the corresponding DataAccessException instance

See Also:

HibernateAccessor.convertHibernateAccessException(org.hibernate.HibernateException), HibernateTransactionManager.convertHibernateAccessException(org.hibernate.HibernateException)

isDeferredCloseActive

public static boolean isDeferredCloseActive(SessionFactory sessionFactory)

Deprecated.

Determine whether deferred close is active for the current thread and the given SessionFactory.

Parameters:

sessionFactory - the Hibernate SessionFactory to check

Returns:

whether deferred close is active

initDeferredClose

public static void initDeferredClose(SessionFactory sessionFactory)

Deprecated.

Initialize deferred close for the current thread and the given SessionFactory. Sessions will not be actually closed on close calls then, but rather at a processDeferredClose(org.hibernate.SessionFactory) call at a finishing point (like request completion).

Used by OpenSessionInViewFilter and OpenSessionInViewInterceptor when not configured for a single session.

Parameters:

sessionFactory - the Hibernate SessionFactory to initialize deferred close for
