```
public abstract class AbstractEntityManagerFactoryBean
extends Object
implements FactoryBean<EntityManagerFactory>, BeanClassLoaderAware, BeanFactoryAware, BeanNameAware, InitializingBean, DisposableBean, EntityManagerFactoryInfo, PersistenceExceptionTranslator, Serializable
```
Abstract FactoryBean that creates a local JPA EntityManagerFactory instance 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 as well as Spring's JpaVendorAdapter abstraction, and controls the EntityManagerFactory's lifecycle.
This class also implements the PersistenceExceptionTranslator interface, as autodetected by Spring's PersistenceExceptionTranslationPostProcessor, 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.

2.0

    BeanInitializationException
  - setBeanName
```
public void setBeanName(String name)
```
    Description copied from interface: BeanNameAware
    
    Set 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:
    
    setBeanName in interface BeanNameAware
    
    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 the BeanFactoryUtils.originalBeanName(String) method to extract the original bean name (without suffix), if desired.
  - afterPropertiesSet
```
public final void afterPropertiesSet()
                              throws PersistenceException
```
    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
    
    Throws:
    
    PersistenceException
  - createEntityManagerFactoryProxy
```
protected EntityManagerFactory createEntityManagerFactoryProxy(EntityManagerFactory emf)
```
    Create a proxy of the given EntityManagerFactory. We do this to be able to return transaction-aware proxies for application-managed EntityManagers, and to introduce the NamedEntityManagerFactory interface
    
    Parameters:
    emf - EntityManagerFactory as returned by the persistence provider
    
    Returns:
    proxy entity manager
  - createNativeEntityManagerFactory
```
protected abstract EntityManagerFactory createNativeEntityManagerFactory()

```
    Subclasses must implement this method to create the EntityManagerFactory that will be returned by the getObject() method.
    
    Returns:
    EntityManagerFactory instance returned by this FactoryBean
    
    Throws:
    
    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:
    
    translateExceptionIfPossible in interface PersistenceExceptionTranslator
    
    Parameters:
    ex - a RuntimeException thrown
    
    Returns:
    the corresponding DataAccessException (or null if the exception could not be translated, as in this case it may result from user code rather than an actual persistence problem)
    See Also:
    PersistenceExceptionTranslationPostProcessor, PersistenceExceptionTranslator.translateExceptionIfPossible(java.lang.RuntimeException), EntityManagerFactoryUtils.convertJpaAccessExceptionIfPossible(java.lang.RuntimeException)
  - getNativeEntityManagerFactory
```
public EntityManagerFactory getNativeEntityManagerFactory()
```
    Description copied from interface: EntityManagerFactoryInfo
    
    Return the raw underlying EntityManagerFactory.
    
    Specified by:
    
    getNativeEntityManagerFactory in interface EntityManagerFactoryInfo
    
    Returns:
    the unadorned EntityManagerFactory (never null)
  - getPersistenceUnitInfo
```
public PersistenceUnitInfo getPersistenceUnitInfo()
```
    Description copied from interface: EntityManagerFactoryInfo
    
    Return the PersistenceUnitInfo used to create this EntityManagerFactory, if the in-container API was used.
    
    Specified by:
    
    getPersistenceUnitInfo in interface EntityManagerFactoryInfo
    
    Returns:
    the PersistenceUnitInfo used to create this EntityManagerFactory, or null if the in-container contract was not used to configure the EntityManagerFactory
  - getDataSource
```
public DataSource getDataSource()
```
    Description copied from interface: EntityManagerFactoryInfo
    
    Return the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.
    
    Specified by:
    
    getDataSource in interface EntityManagerFactoryInfo
    
    Returns:
    the JDBC DataSource, or null if not known
  - getObject
```
public EntityManagerFactory getObject()
```
    Return the singleton EntityManagerFactory.
    
    Specified by:
    
    getObject in interface FactoryBean<EntityManagerFactory>
    
    Returns:
    an instance of the bean (can be null)
    See Also:
    FactoryBeanNotInitializedException
  - getObjectType
```
public Class<? extends EntityManagerFactory> getObjectType()
```
    Description copied from interface: FactoryBean
    
    Return the type of object that this FactoryBean creates, or null if 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 null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.
    
    Specified by:
    
    getObjectType in interface FactoryBean<EntityManagerFactory>
    
    Returns:
    the type of object that this FactoryBean creates, or null if not known at the time of the call
    See Also:
    ListableBeanFactory.getBeansOfType(java.lang.Class<T>)
  - isSingleton
```
public boolean isSingleton()
```
    Description copied from interface: FactoryBean
    
    Is the object managed by this factory a singleton? That is, will FactoryBean.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 return true unless 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 false does not necessarily indicate that returned objects are independent instances. An implementation of the extended SmartFactoryBean interface may explicitly indicate independent instances through its SmartFactoryBean.isPrototype() method. Plain FactoryBean implementations which do not implement this extended interface are simply assumed to always return independent instances if the isSingleton() implementation returns false.
    
    Specified by:
    
    isSingleton in interface FactoryBean<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:
    
    destroy in interface DisposableBean
  - writeReplace
```
protected Object writeReplace()
                       throws ObjectStreamException
```
    Throws:
    
    ObjectStreamException
