Field Detail

FLUSH_NEVER

public static final int FLUSH_NEVER

Deprecated.

Never flush is a good strategy for read-only units of work. Hibernate will not track and look for changes in this case, avoiding any overhead of modification detection.

In case of an existing Session, FLUSH_NEVER will turn the flush mode to NEVER for the scope of the current operation, resetting the previous flush mode afterwards.

See Also:

setFlushMode(int), Constant Field Values

FLUSH_AUTO

public static final int FLUSH_AUTO

Deprecated.

Automatic flushing is the default mode for a Hibernate Session. A session will get flushed on transaction commit, and on certain find operations that might involve already modified instances, but not after each unit of work like with eager flushing.

In case of an existing Session, FLUSH_AUTO will participate in the existing flush mode, not modifying it for the current operation. This in particular means that this setting will not modify an existing flush mode NEVER, in contrast to FLUSH_EAGER.

See Also:

setFlushMode(int), Constant Field Values

FLUSH_EAGER

public static final int FLUSH_EAGER

Deprecated.

Eager flushing leads to immediate synchronization with the database, even if in a transaction. This causes inconsistencies to show up and throw a respective exception immediately, and JDBC access code that participates in the same transaction will see the changes as the database is already aware of them then. But the drawbacks are:

• additional communication roundtrips with the database, instead of a single batch at transaction commit;
• the fact that an actual database rollback is needed if the Hibernate transaction rolls back (due to already submitted SQL statements).

In case of an existing Session, FLUSH_EAGER will turn the flush mode to AUTO for the scope of the current operation and issue a flush at the end, resetting the previous flush mode afterwards.

See Also:

setFlushMode(int), Constant Field Values

FLUSH_COMMIT

public static final int FLUSH_COMMIT

Deprecated.

Flushing at commit only is intended for units of work where no intermediate flushing is desired, not even for find operations that might involve already modified instances.

In case of an existing Session, FLUSH_COMMIT will turn the flush mode to COMMIT for the scope of the current operation, resetting the previous flush mode afterwards. The only exception is an existing flush mode NEVER, which will not be modified through this setting.

See Also:

setFlushMode(int), Constant Field Values

FLUSH_ALWAYS

public static final int FLUSH_ALWAYS

Deprecated.

Flushing before every query statement is rarely necessary. It is only available for special needs.

In case of an existing Session, FLUSH_ALWAYS will turn the flush mode to ALWAYS for the scope of the current operation, resetting the previous flush mode afterwards.

Constructor Detail

HibernateAccessor

public HibernateAccessor()

Deprecated.

Method Detail

setSessionFactory

public void setSessionFactory(SessionFactory sessionFactory)

Deprecated.

Set the Hibernate SessionFactory that should be used to create Hibernate Sessions.

getSessionFactory

public SessionFactory getSessionFactory()

Deprecated.

Return the Hibernate SessionFactory that should be used to create Hibernate Sessions.

setEntityInterceptorBeanName

public void setEntityInterceptorBeanName(java.lang.String entityInterceptorBeanName)

Deprecated.

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.

Parameters:

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

See Also:

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

setEntityInterceptor

public void setEntityInterceptor(Interceptor entityInterceptor)

Deprecated.

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 object.

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.

See Also:

setEntityInterceptorBeanName(java.lang.String), LocalSessionFactoryBean.setEntityInterceptor(Interceptor), HibernateTransactionManager.setEntityInterceptor(Interceptor)

getEntityInterceptor

public Interceptor getEntityInterceptor()
                                 throws java.lang.IllegalStateException,
                                        BeansException

Deprecated.

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

Throws:

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

BeansException - if bean name resolution via the bean factory failed

See Also:

setEntityInterceptor(Interceptor), setEntityInterceptorBeanName(java.lang.String), setBeanFactory(org.springframework.beans.factory.BeanFactory)

setJdbcExceptionTranslator

public void setJdbcExceptionTranslator(SQLExceptionTranslator jdbcExceptionTranslator)

Deprecated.

Set the JDBC exception translator for this instance.

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

Parameters:

jdbcExceptionTranslator - the exception translator

See Also:

SQLException, org.hibernate.JDBCException, SQLErrorCodeSQLExceptionTranslator, SQLStateSQLExceptionTranslator

getJdbcExceptionTranslator

public SQLExceptionTranslator getJdbcExceptionTranslator()

Deprecated.

Return the JDBC exception translator for this instance, if any.

setFlushModeName

public void setFlushModeName(java.lang.String constantName)

Deprecated.

Set the flush behavior by the name of the respective constant in this class, e.g. "FLUSH_AUTO". Default is "FLUSH_AUTO".

Parameters:

constantName - name of the constant

See Also:

setFlushMode(int), FLUSH_AUTO

setFlushMode

public void setFlushMode(int flushMode)

Deprecated.

getFlushMode

public int getFlushMode()

Deprecated.

Return if a flush should be forced after executing the callback code.

setFilterName

public void setFilterName(java.lang.String filter)

Deprecated.

Set the name of a Hibernate filter to be activated for all Sessions that this accessor works with.

This filter will be enabled at the beginning of each operation and correspondingly disabled at the end of the operation. This will work for newly opened Sessions as well as for existing Sessions (for example, within a transaction).

See Also:

#enableFilters(org.hibernate.Session), org.hibernate.Session#enableFilter(String), LocalSessionFactoryBean.setFilterDefinitions(FilterDefinition...)

setFilterNames

public void setFilterNames(java.lang.String... filterNames)

Deprecated.

Set one or more names of Hibernate filters to be activated for all Sessions that this accessor works with.

Each of those filters will be enabled at the beginning of each operation and correspondingly disabled at the end of the operation. This will work for newly opened Sessions as well as for existing Sessions (for example, within a transaction).

See Also:

#enableFilters(org.hibernate.Session), org.hibernate.Session#enableFilter(String), LocalSessionFactoryBean.setFilterDefinitions(FilterDefinition...)

getFilterNames

public java.lang.String[] getFilterNames()

Deprecated.

Return the names of Hibernate filters to be activated, if any.

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

Deprecated.

The bean factory just needs to be known for resolving entity interceptor bean names. It does not need to be set for any other mode of operation.

afterPropertiesSet

public void afterPropertiesSet()

Deprecated.

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean
