public abstract class AbstractEntityManagerFactoryBean extends Object implements FactoryBean<EntityManagerFactory>, BeanClassLoaderAware, BeanFactoryAware, BeanNameAware, InitializingBean, DisposableBean, EntityManagerFactoryInfo, PersistenceExceptionTranslator, Serializable
AbstractFactoryBeanthat creates a local JPAEntityManagerFactoryinstance within a Spring application context.Encapsulates the common functionality between the different JPA bootstrap contracts (standalone as well as container).
Implements support for standard JPA configuration conventions as well as Spring's customizable
JpaVendorAdaptermechanism, and controls the EntityManagerFactory's lifecycle.This class also implements the
PersistenceExceptionTranslatorinterface, as autodetected by Spring'sPersistenceExceptionTranslationPostProcessor, for AOP-based translation of native exceptions to Spring DataAccessExceptions. Hence, the presence of e.g. LocalEntityManagerFactoryBean automatically enables a PersistenceExceptionTranslationPostProcessor to translate JPA exceptions.- Since:

Method Detail
setPersistenceProviderClass
public void setPersistenceProviderClass(Class<? extends PersistenceProvider> persistenceProviderClass)
Set the PersistenceProvider implementation class to use for creating the EntityManagerFactory. If not specified, the persistence provider will be taken from the JpaVendorAdapter (if any) or retrieved through scanning (as far as possible).
setPersistenceProvider
public void setPersistenceProvider(PersistenceProvider persistenceProvider)
Set the PersistenceProvider instance to use for creating the EntityManagerFactory. If not specified, the persistence provider will be taken from the JpaVendorAdapter (if any) or determined by the persistence unit deployment descriptor (as far as possible).
getPersistenceProvider
public PersistenceProvider getPersistenceProvider()
Description copied from interface:EntityManagerFactoryInfoReturn the underlying PersistenceProvider that the underlying EntityManagerFactory was created with.- Specified by:
getPersistenceProviderin interfaceEntityManagerFactoryInfo- Returns:
- the PersistenceProvider used to create this EntityManagerFactory, or
nullif the standard JPA provider autodetection process was used to configure the EntityManagerFactory
setPersistenceUnitName
public void setPersistenceUnitName(String persistenceUnitName)
Specify the name of the EntityManagerFactory configuration.Default is none, indicating the default EntityManagerFactory configuration. The persistence provider will throw an exception if ambiguous EntityManager configurations are found.
getPersistenceUnitName
public String getPersistenceUnitName()
Description copied from interface:EntityManagerFactoryInfoReturn the name of the persistence unit used to create this EntityManagerFactory, ornullif it is an unnamed default.If
getPersistenceUnitInfo()returns non-null, the result ofgetPersistenceUnitName()must be equal to the value returned byPersistenceUnitInfo.getPersistenceUnitName().- Specified by:
getPersistenceUnitNamein interfaceEntityManagerFactoryInfo- See Also:
EntityManagerFactoryInfo.getPersistenceUnitInfo(),PersistenceUnitInfo.getPersistenceUnitName()
setJpaProperties
public void setJpaProperties(Properties jpaProperties)
Specify JPA properties, to be passed intoPersistence.createEntityManagerFactory(if any).Can be populated with a String "value" (parsed via PropertiesEditor) or a "props" element in XML bean definitions.
setJpaPropertyMap
public void setJpaPropertyMap(Map<String,?> jpaProperties)
Specify JPA properties as a Map, to be passed intoPersistence.createEntityManagerFactory(if any).Can be populated with a "map" or "props" element in XML bean definitions.
getJpaPropertyMap
public Map<String,Object> getJpaPropertyMap()
Allow Map access to the JPA properties to be passed to the persistence provider, with the option to add or override specific entries.Useful for specifying entries directly, for example via "jpaPropertyMap[myKey]".
setEntityManagerFactoryInterface
public void setEntityManagerFactoryInterface(Class<? extends EntityManagerFactory> emfInterface)
Specify the (potentially vendor-specific) EntityManagerFactory interface that this EntityManagerFactory proxy is supposed to implement.The default will be taken from the specific JpaVendorAdapter, if any, or set to the standard
javax.persistence.EntityManagerFactoryinterface else.
setEntityManagerInterface
public void setEntityManagerInterface(Class<? extends EntityManager> emInterface)
Specify the (potentially vendor-specific) EntityManager interface that this factory's EntityManagers are supposed to implement.The default will be taken from the specific JpaVendorAdapter, if any, or set to the standard
javax.persistence.EntityManagerinterface else.
getEntityManagerInterface
public Class<? extends EntityManager> getEntityManagerInterface()
Description copied from interface:EntityManagerFactoryInfoReturn the (potentially vendor-specific) EntityManager interface that this factory's EntityManagers will implement.A
nullreturn value suggests that autodetection is supposed to happen: either based on a targetEntityManagerinstance or simply defaulting tojavax.persistence.EntityManager.- Specified by:
getEntityManagerInterfacein interfaceEntityManagerFactoryInfo
setJpaDialect
public void setJpaDialect(JpaDialect jpaDialect)
Specify the vendor-specific JpaDialect implementation to associate with this EntityManagerFactory. This will be exposed through the EntityManagerFactoryInfo interface, to be picked up as default dialect by accessors that intend to use JpaDialect functionality.
getJpaDialect
public JpaDialect getJpaDialect()
Description copied from interface:EntityManagerFactoryInfoReturn the vendor-specific JpaDialect implementation for this EntityManagerFactory, ornullif not known.- Specified by:
getJpaDialectin interfaceEntityManagerFactoryInfo
setJpaVendorAdapter
public void setJpaVendorAdapter(JpaVendorAdapter jpaVendorAdapter)
Specify the JpaVendorAdapter implementation for the desired JPA provider, if any. This will initialize appropriate defaults for the given provider, such as persistence provider class and JpaDialect, unless locally overridden in this FactoryBean.
getJpaVendorAdapter
public JpaVendorAdapter getJpaVendorAdapter()
Return the JpaVendorAdapter implementation for this EntityManagerFactory, ornullif not known.
setBootstrapExecutor
public void setBootstrapExecutor(AsyncTaskExecutor bootstrapExecutor)
Specify an asynchronous executor for background bootstrapping, e.g. aSimpleAsyncTaskExecutor.EntityManagerFactoryinitialization will then switch into background bootstrap mode, with aEntityManagerFactoryproxy immediately returned for injection purposes instead of waiting for the JPA provider's bootstrapping to complete. However, note that the first actual call to aEntityManagerFactorymethod will then block until the JPA provider's bootstrapping completed, if not ready by then. For maximum benefit, make sure to avoid earlyEntityManagerFactorycalls in init methods of related beans, even for metadata introspection purposes.- Since:
- 4.3
getBootstrapExecutor
public AsyncTaskExecutor getBootstrapExecutor()
Return the asynchronous executor for background bootstrapping, if any.- Since:
- 4.3
setBeanClassLoader
public void setBeanClassLoader(ClassLoader classLoader)
Description copied from interface:BeanClassLoaderAwareCallback that supplies the beanclass loaderto a bean instance.Invoked after the population of normal bean properties but before an initialization callback such as
InitializingBean'sInitializingBean.afterPropertiesSet()method or a custom init-method.- Specified by:
setBeanClassLoaderin interfaceBeanClassLoaderAware- Parameters:
classLoader- the owning class loader; may benullin which case a defaultClassLoadermust be used, for example theClassLoaderobtained viaClassUtils.getDefaultClassLoader()
getBeanClassLoader
public ClassLoader getBeanClassLoader()
Description copied from interface:EntityManagerFactoryInfoReturn the ClassLoader that the application's beans are loaded with.Proxies will be generated in this ClassLoader.
- Specified by:
getBeanClassLoaderin interfaceEntityManagerFactoryInfo
setBeanFactory
public void setBeanFactory(BeanFactory beanFactory)
Description copied from interface:BeanFactoryAwareCallback that supplies the owning factory to a bean instance.Invoked after the population of normal bean properties but before an initialization callback such as
InitializingBean.afterPropertiesSet()or a custom init-method.- Specified by:
setBeanFactoryin interfaceBeanFactoryAware- Parameters:
beanFactory- owning BeanFactory (nevernull). The bean can immediately call methods on the factory.- See Also:
BeanInitializationException
setBeanName
public void setBeanName(String name)
Description copied from interface:BeanNameAwareSet the name of the bean in the bean factory that created this bean.Invoked after population of normal bean properties but before an init callback such as
InitializingBean.afterPropertiesSet()or a custom init-method.- Specified by:
setBeanNamein interfaceBeanNameAware- Parameters:
name- the name of the bean in the factory. Note that this name is the actual bean name used in the factory, which may differ from the originally specified name: in particular for inner bean names, the actual bean name might have been made unique through appending "#..." suffixes. Use theBeanFactoryUtils.originalBeanName(String)method to extract the original bean name (without suffix), if desired.
afterPropertiesSet
public void afterPropertiesSet() throws PersistenceException
Description copied from interface:InitializingBeanInvoked by the containingBeanFactoryafter it has set all bean properties and satisfiedBeanFactoryAware,ApplicationContextAwareetc.This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
- Specified by:
afterPropertiesSetin interfaceInitializingBean- Throws:
PersistenceException
createEntityManagerFactoryProxy
protected EntityManagerFactory createEntityManagerFactoryProxy(EntityManagerFactory emf)
Create a proxy for the givenEntityManagerFactory. We do this to be able to return a transaction-aware proxy for an application-managedEntityManager.- Parameters:
emf- the EntityManagerFactory as returned by the persistence provider, if initialized already- Returns:
- the EntityManagerFactory proxy
createNativeEntityManagerFactory
protected abstract EntityManagerFactory createNativeEntityManagerFactory() throws PersistenceException
Subclasses must implement this method to create the EntityManagerFactory that will be returned by thegetObject()method.- Returns:

PersistenceException- if the EntityManager cannot be created
translateExceptionIfPossible
public DataAccessException translateExceptionIfPossible(RuntimeException ex)
Implementation of the PersistenceExceptionTranslator interface, as autodetected by Spring's PersistenceExceptionTranslationPostProcessor.Uses the dialect's conversion if possible; otherwise falls back to standard JPA exception conversion.
- Specified by:
translateExceptionIfPossiblein interfacePersistenceExceptionTranslator- Parameters:
ex- a RuntimeException to translate- Returns:
- the corresponding DataAccessException (or
nullif the exception could not be translated, as in this case it may result from user code rather than from an actual persistence problem) - See Also:
PersistenceExceptionTranslationPostProcessor,PersistenceExceptionTranslator.translateExceptionIfPossible(java.lang.RuntimeException),EntityManagerFactoryUtils.convertJpaAccessExceptionIfPossible(java.lang.RuntimeException)
getNativeEntityManagerFactory
public EntityManagerFactory getNativeEntityManagerFactory()

getNativeEntityManagerFactoryin interfaceEntityManagerFactoryInfo- Returns:
- the unadorned EntityManagerFactory (never
null)
getPersistenceUnitInfo
public PersistenceUnitInfo getPersistenceUnitInfo()
Description copied from interface:EntityManagerFactoryInfoReturn the PersistenceUnitInfo used to create this EntityManagerFactory, if the in-container API was used.- Specified by:
getPersistenceUnitInfoin interfaceEntityManagerFactoryInfo- Returns:
- the PersistenceUnitInfo used to create this EntityManagerFactory, or
nullif the in-container contract was not used to configure the EntityManagerFactory
getDataSource
public DataSource getDataSource()
Description copied from interface:EntityManagerFactoryInfoReturn the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.- Specified by:
getDataSourcein interfaceEntityManagerFactoryInfo- Returns:
- the JDBC DataSource, or
nullif not known
getObject
public EntityManagerFactory getObject()
Return the singleton EntityManagerFactory.- Specified by:
getObjectin interfaceFactoryBean<EntityManagerFactory>- Returns:
- an instance of the bean (can be
null) - See Also:
FactoryBeanNotInitializedException
getObjectType
public Class<? extends EntityManagerFactory> getObjectType()
Description copied from interface:FactoryBeanReturn the type of object that this FactoryBean creates, ornullif not known in advance.This allows one to check for specific types of beans without instantiating objects, for example on autowiring.
In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return
nullhere. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.- Specified by:
getObjectTypein interfaceFactoryBean<EntityManagerFactory>- Returns:
- the type of object that this FactoryBean creates, or
nullif not known at the time of the call - See Also:
ListableBeanFactory.getBeansOfType(java.lang.Class<T>)
isSingleton
public boolean isSingleton()
Description copied from interface:FactoryBeanIs the object managed by this factory a singleton? That is, willFactoryBean.getObject()always return the same object (a reference that can be cached)?NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from
getObject()might get cached by the owning BeanFactory. Hence, do not returntrueunless the FactoryBean always exposes the same reference.The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.
NOTE: This method returning
falsedoes not necessarily indicate that returned objects are independent instances. An implementation of the extendedSmartFactoryBeaninterface may explicitly indicate independent instances through itsSmartFactoryBean.isPrototype()method. PlainFactoryBeanimplementations which do not implement this extended interface are simply assumed to always return independent instances if theisSingleton()implementation returnsfalse.- Specified by:
isSingletonin interfaceFactoryBean<EntityManagerFactory>- Returns:
- whether the exposed object is a singleton
- See Also:
FactoryBean.getObject(),SmartFactoryBean.isPrototype()
destroy
public void destroy()
Close the EntityManagerFactory on bean factory shutdown.- Specified by:
destroyin interfaceDisposableBean
writeReplace
protected Object writeReplace() throws ObjectStreamException
- Throws:
ObjectStreamException
