      public class LocalSessionFactoryBean
      extends AbstractSessionFactoryBean
      implements BeanClassLoaderAware

  `FactoryBean` that creates a Hibernate `SessionFactory`. This is the usual way to set up a shared Hibernate SessionFactory in a Spring application context; the SessionFactory can then be passed to Hibernate-based DAOs via dependency injection.

  Configuration settings can either be read from a Hibernate XML file, specified as "configLocation", or completely via this class. A typical local configuration consists of one or more "mappingResources", various "hibernateProperties" (not strictly necessary), and a "dataSource" that the SessionFactory should use. The latter can also be specified via Hibernate properties, but "dataSource" supports any Spring-configured DataSource, instead of relying on Hibernate's own connection providers.

  This SessionFactory handling strategy is appropriate for most types of applications, from Hibernate-only single database apps to ones that need distributed transactions. Either `HibernateTransactionManager` or `JtaTransactionManager` can be used for transaction demarcation, with the latter only necessary for transactions which span multiple databases.

  This factory bean will by default expose a transaction-aware SessionFactory proxy, letting data access code work with the plain Hibernate SessionFactory and its `getCurrentSession()` method, while still being able to participate in current Spring-managed transactions: with any transaction management strategy, either local or JTA / EJB CMT, and any transaction synchronization mechanism, either Spring or JTA. Furthermore, `getCurrentSession()` will also seamlessly work with a request-scoped Session managed by `OpenSessionInViewFilter` / `OpenSessionInViewInterceptor`.

  Requires Hibernate 3.2 or later; tested with 3.3, 3.5 and 3.6. Note that this factory will use "on_close" as default Hibernate connection release mode, unless in the case of a "jtaTransactionManager" specified, for the reason that this is appropriate for most Spring-based applications (in particular when using Spring's HibernateTransactionManager).

      Can be set to "org.hibernate.cfg.AnnotationConfiguration" for using Hibernate3 annotation support (initially only available as alpha download separate from the main Hibernate3 distribution).

      Annotated packages and annotated classes can be specified via the corresponding tags in "hibernate.cfg.xml" then, so this will usually be combined with a "configLocation" property that points at such a standard Hibernate configuration file.

      See Also:
        `setConfigLocation(org.springframework.core.io.Resource)`, `Configuration`, `AnnotationConfiguration`

    - #### setConfigLocation

          public void setConfigLocation(Resource configLocation)

      Set the location of a single Hibernate XML config file, for example as classpath resource "classpath:hibernate.cfg.xml".

      Note: Can be omitted when all necessary properties and mapping resources are specified locally via this bean.

          public void setMappingResources(String[] mappingResources)

      Set Hibernate mapping resources to be found in the class path, like "example.hbm.xml" or "mypackage/example.hbm.xml". Analogous to mapping entries in a Hibernate XML config file. Alternative to the more generic setMappingLocations method.

      Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

      See Also:
        `setMappingLocations(org.springframework.core.io.Resource[])`, `Configuration.addResource(java.lang.String, java.lang.ClassLoader)`

    - #### setMappingLocations

          public void setMappingLocations(Resource[] mappingLocations)

      Set locations of Hibernate mapping files, for example as classpath resource "classpath:example.hbm.xml". Supports any resource location via Spring's resource abstraction, for example relative paths like "WEB-INF/mappings/example.hbm.xml" when running in an application context.

      Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

      See Also:
        `Configuration.addInputStream(java.io.InputStream)`

    - #### setCacheableMappingLocations

          public void setCacheableMappingLocations(Resource[] cacheableMappingLocations)

      Set locations of cacheable Hibernate mapping files, for example as web app resource "/WEB-INF/mapping/example.hbm.xml". Supports any resource location via Spring's resource abstraction, as long as the resource can be resolved in the file system.

          public void setMappingJarLocations(Resource[] mappingJarLocations)

      Set locations of jar files that contain Hibernate mapping resources, like "WEB-INF/lib/example.hbm.jar".

      Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

      See Also:
        `Configuration.addJar(java.io.File)`

    - #### setMappingDirectoryLocations

    - #### setHibernateProperties

          public void setHibernateProperties(Properties hibernateProperties)

      Set Hibernate properties, such as "hibernate.dialect".

      Can be used to override values in a Hibernate XML config file, or to specify all necessary properties locally.

      Note: Do not specify a transaction provider here when using Spring-driven transactions. It is also advisable to omit connection provider settings and use a Spring-set DataSource instead.

      See Also:
        `AbstractSessionFactoryBean.setDataSource(javax.sql.DataSource)`

    - #### getHibernateProperties

          public Properties getHibernateProperties()

    - #### setJtaTransactionManager

          public void setJtaTransactionManager(TransactionManager jtaTransactionManager)

      Set the JTA TransactionManager to be used for Hibernate's TransactionManagerLookup. Allows for using a Spring-managed JTA TransactionManager for Hibernate's cache synchronization.

      Note: If this is set, the Hibernate settings should not define a transaction manager lookup to avoid meaningless double configuration.

      See Also:
        `LocalTransactionManagerLookup`

    - #### setCacheRegionFactory

          public void setCacheRegionFactory(Object cacheRegionFactory)

      Set the Hibernate RegionFactory to use for the SessionFactory. Allows for using a Spring-managed RegionFactory instance.

      As of Hibernate 3.3, this is the preferred mechanism for configuring caches, superseding the `CacheProvider SPI`. For Hibernate 3.2 compatibility purposes, the accepted reference is of type Object: the actual type is `org.hibernate.cache.RegionFactory`.

      Note: If this is set, the Hibernate settings should not define a cache provider to avoid meaningless double configuration.

      See Also:
        `RegionFactory`

    - #### setCacheProvider

          @Deprecated
          public void setCacheProvider(CacheProvider cacheProvider)

      Deprecated. as of Spring 3.0, following Hibernate 3.3's deprecation of the CacheProvider SPI
      Set the Hibernate CacheProvider to use for the SessionFactory. Allows for using a Spring-managed CacheProvider instance.

      Note: If this is set, the Hibernate settings should not define a cache provider to avoid meaningless double configuration.

      See Also:
        `setCacheRegionFactory(java.lang.Object)`

    - #### setLobHandler

          public void setLobHandler(LobHandler lobHandler)

      Set the LobHandler to be used by the SessionFactory. Will be exposed at config time for UserType implementations.
      See Also:
        `getConfigTimeLobHandler()`, `UserType`, `ClobStringType`, `BlobByteArrayType`, `BlobSerializableType`

    - #### setEntityInterceptor

          public void setEntityInterceptor(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 factory.

      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:
        `HibernateAccessor.setEntityInterceptor(org.hibernate.Interceptor)`, `HibernateAccessor.setEntityInterceptor(org.hibernate.Interceptor)`, `HibernateTransactionManager.setEntityInterceptor(org.hibernate.Interceptor)`, `Configuration.setInterceptor(org.hibernate.Interceptor)`

    - #### setNamingStrategy

          public void setNamingStrategy(NamingStrategy namingStrategy)

      Set a Hibernate NamingStrategy for the SessionFactory, determining the physical column and table names given the info in the mapping document.

        `Configuration.setNamingStrategy(org.hibernate.cfg.NamingStrategy)`

    - #### setTypeDefinitions

          public void setTypeDefinitions(TypeDefinitionBean[] typeDefinitions)

      Specify the Hibernate type definitions to register with the SessionFactory, as Spring TypeDefinitionBean instances. This is an alternative to specifying <<typedef> elements in Hibernate mapping files.

      Unfortunately, Hibernate itself does not define a complete object that represents a type definition, hence the need for Spring's TypeDefinitionBean.

      See Also:
        `TypeDefinitionBean`, `Mappings.addTypeDef(String, String, java.util.Properties)`

    - #### setFilterDefinitions

          public void setFilterDefinitions(FilterDefinition[] filterDefinitions)

      Specify the Hibernate FilterDefinitions to register with the SessionFactory. This is an alternative to specifying <<filter-def> elements in Hibernate mapping files.

      Typically, the passed-in FilterDefinition objects will have been defined as Spring FilterDefinitionFactoryBeans, probably as inner beans within the LocalSessionFactoryBean definition.

      See Also:
        `FilterDefinitionFactoryBean`, `Configuration.addFilterDefinition(org.hibernate.engine.spi.FilterDefinition)`

    - #### setEntityCacheStrategies

          public void setEntityCacheStrategies(Properties entityCacheStrategies)

      Specify the cache strategies for entities (persistent classes or named entities). This configuration setting corresponds to the <class-cache> entry in the "hibernate.cfg.xml" configuration format.

      For example:

           <property name="entityCacheStrategies">
             <props>
               <prop key="com.mycompany.Customer">read-write</prop>
               <prop key="com.mycompany.Product">read-only,myRegion</prop>
             </props>
           </property>

      Parameters:
        `entityCacheStrategies` - properties that define entity cache strategies, with class names as keys and cache concurrency strategies as values
      See Also:
        `Configuration.setCacheConcurrencyStrategy(String, String)`

    - #### setCollectionCacheStrategies

          public void setCollectionCacheStrategies(Properties collectionCacheStrategies)

      Specify the cache strategies for persistent collections (with specific roles). This configuration setting corresponds to the <collection-cache> entry in the "hibernate.cfg.xml" configuration format.

      For example:

           <property name="collectionCacheStrategies">
             <props>
               <prop key="com.mycompany.Order.items">read-write</prop>
               <prop key="com.mycompany.Product.categories">read-only,myRegion</prop>
             </props>
           </property>

      Parameters:
        `collectionCacheStrategies` - properties that define collection cache strategies, with collection roles as keys and cache concurrency strategies as values
      See Also:
        `Configuration.setCollectionCacheConcurrencyStrategy(String, String)`

    - #### setEventListeners

          public void setEventListeners(Map<String,Object> eventListeners)

      Specify the Hibernate event listeners to register, with listener types as keys and listener objects as values. Instead of a single listener object, you can also pass in a list or set of listeners objects as value.

      See the Hibernate documentation for further details on listener types and associated listener interfaces.

      See `org.hibernate.cfg.Configuration#setListener(String, Object)`

      Parameters:
        `eventListeners` - Map with listener type Strings as keys and listener objects as values

    - #### setSchemaUpdate

          public void setSchemaUpdate(boolean schemaUpdate)

      Set whether to execute a schema update after SessionFactory initialization.

      For details on how to make schema update scripts work, see the Hibernate documentation, as this class leverages the same schema update script support in org.hibernate.cfg.Configuration as Hibernate's own SchemaUpdate tool.

      See Also:
        `Configuration.generateSchemaUpdateScript(org.hibernate.dialect.Dialect, org.hibernate.tool.hbm2ddl.DatabaseMetadata)`, `SchemaUpdate`

    - #### setBeanClassLoader

    - #### destroy

          public void destroy()
                       throws HibernateException

      Allows for schema export on shutdown.
      Specified by:
        `destroy` in interface `DisposableBean`
      Overrides:
        `destroy` in class `AbstractSessionFactoryBean`
      Throws:
        `HibernateException`

    - #### updateDatabaseSchema

          public void updateDatabaseSchema()
                                    throws DataAccessException

      Execute schema update script, determined by the Configuration object used for creating the SessionFactory. A replacement for Hibernate's SchemaUpdate class, for automatically executing schema update scripts on application startup. Can also be invoked manually.

      Fetch the LocalSessionFactoryBean itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via `LocalSessionFactoryBean lsfb = (LocalSessionFactoryBean) ctx.getBean("&mySessionFactory");`.

      Uses the SessionFactory that this bean generates for accessing a JDBC connection to perform the script.

      Throws:
        `DataAccessException` - in case of script execution errors
      See Also:
        `setSchemaUpdate(boolean)`, `Configuration.generateSchemaUpdateScript(org.hibernate.dialect.Dialect, org.hibernate.tool.hbm2ddl.DatabaseMetadata)`, `SchemaUpdate`

    - #### validateDatabaseSchema

          public void validateDatabaseSchema()
                                      throws DataAccessException

      Execute schema creation script, determined by the Configuration object used for creating the SessionFactory. A replacement for Hibernate's SchemaValidator class, to be invoked after application startup.

      Fetch the LocalSessionFactoryBean itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via `LocalSessionFactoryBean lsfb = (LocalSessionFactoryBean) ctx.getBean("&mySessionFactory");`.

      Uses the SessionFactory that this bean generates for accessing a JDBC connection to perform the script.

      Throws:
        `DataAccessException` - in case of script execution errors

    - #### dropDatabaseSchema

          public void dropDatabaseSchema()
                                  throws DataAccessException

      Execute schema drop script, determined by the Configuration object used for creating the SessionFactory. A replacement for Hibernate's SchemaExport class, to be invoked on application setup.

      Fetch the LocalSessionFactoryBean itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via `LocalSessionFactoryBean lsfb = (LocalSessionFactoryBean) ctx.getBean("&mySessionFactory");`.

      Uses the SessionFactory that this bean generates for accessing a JDBC connection to perform the script.

      Throws:
        `DataAccessException` - in case of script execution errors

        `Configuration.generateDropSchemaScript(org.hibernate.dialect.Dialect)`, `SchemaExport.drop(boolean, boolean)`

    - #### createDatabaseSchema

          public void createDatabaseSchema()
                                    throws DataAccessException

      Execute schema creation script, determined by the Configuration object used for creating the SessionFactory. A replacement for Hibernate's SchemaExport class, to be invoked on application setup.

      Fetch the LocalSessionFactoryBean itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via `LocalSessionFactoryBean lsfb = (LocalSessionFactoryBean) ctx.getBean("&mySessionFactory");`.

      Uses the SessionFactory that this bean generates for accessing a JDBC connection to perform the script.

        `Configuration.generateSchemaCreationScript(org.hibernate.dialect.Dialect)`, `SchemaExport.create(boolean, boolean)`

    - #### executeSchemaScript

          protected void executeSchemaScript(Connection con,
                                 String[] sql)
                                      throws SQLException

      Execute the given schema script on the given JDBC Connection.

      Note that the default implementation will log unsuccessful statements and continue to execute. Override the `executeSchemaStatement` method to treat failures differently.

      Parameters:
        `con` - the JDBC Connection to execute the script on
        `sql` - the SQL statements to execute
      Throws:
        `SQLException` - if thrown by JDBC methods
      See Also:
        `executeSchemaStatement(java.sql.Statement, java.lang.String)`

    - #### executeSchemaStatement

          protected void executeSchemaStatement(Statement stmt,
                                    String sql)
                                         throws SQLException

      Execute the given schema SQL on the given JDBC Statement.

      Note that the default implementation will log unsuccessful statements and continue to execute. Override this method to treat failures differently.

      Parameters:
        `stmt` - the JDBC Statement to execute the SQL on
        `sql` - the SQL statement to execute
      Throws:
        `SQLException` - if thrown by JDBC methods (and considered fatal)
