## org.springframework.orm.jpa.vendor
Class HibernateJpaVendorAdapter

    java.lang.Object
      org.springframework.orm.jpa.vendor.AbstractJpaVendorAdapter
          org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter

All Implemented Interfaces:
  JpaVendorAdapter

    public class HibernateJpaVendorAdapter

extends AbstractJpaVendorAdapter

`JpaVendorAdapter` implementation for Hibernate EntityManager. Developed and tested against Hibernate 3.3.

Exposes Hibernate's persistence provider and EntityManager extension interface, and supports `AbstractJpaVendorAdapter`'s common configuration settings.

Method Summary
`protected Class` | `determineDatabaseDialectClass(Database database)` Determine the Hibernate database dialect class for the given target database.
`Class<? extends javax.persistence.EntityManagerFactory>` | `getEntityManagerFactoryInterface()` Return the vendor-specific EntityManagerFactory interface that the EntityManagerFactory proxy is supposed to implement.
`Class<? extends javax.persistence.EntityManager>` | `getEntityManagerInterface()` Return the vendor-specific EntityManager interface that this provider's EntityManagers will implement.
`JpaDialect` | `getJpaDialect()` Return the vendor-specific JpaDialect implementation for this provider, or `null` if there is none.
`Map<String,Object>` | `getJpaPropertyMap()` Return a Map of vendor-specific JPA properties, typically based on settings in this JpaVendorAdapter instance.
`javax.persistence.spi.PersistenceProvider` | `getPersistenceProvider()` Return the vendor-specific persistence provider.

Method Detail

### getPersistenceProvider

    public javax.persistence.spi.PersistenceProvider getPersistenceProvider()

  Description copied from interface: `JpaVendorAdapter`
  Return the vendor-specific persistence provider.

### getPersistenceProviderRootPackage

    public String getPersistenceProviderRootPackage()

  Description copied from interface: `JpaVendorAdapter`
  Return the name of the persistence provider's root package (e.g. "oracle.toplink.essentials"). Will be used for excluding provider classes from temporary class overriding.

  Specified by:
    `getPersistenceProviderRootPackage` in interface `JpaVendorAdapter`
  Overrides:
    `getPersistenceProviderRootPackage` in class `AbstractJpaVendorAdapter`

### getJpaPropertyMap

    public Map<String,Object> getJpaPropertyMap()

  Description copied from interface: `JpaVendorAdapter`
  Return a Map of vendor-specific JPA properties, typically based on settings in this JpaVendorAdapter instance.

  Note that there might be further JPA properties defined on the EntityManagerFactory bean, which might potentially override individual JPA property values specified here.

  Specified by:
    `getJpaPropertyMap` in interface `JpaVendorAdapter`
  Overrides:
    `getJpaPropertyMap` in class `AbstractJpaVendorAdapter`
  Returns:
    a Map of JPA properties, as as accepted by the standard JPA bootstrap facilities, or `null` or an empty Map if there are no such properties to expose
  See Also:
    `Persistence.createEntityManagerFactory(String, java.util.Map)`, `PersistenceProvider.createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo, java.util.Map)`

### determineDatabaseDialectClass

    protected Class determineDatabaseDialectClass(Database database)

  Determine the Hibernate database dialect class for the given target database.

  Parameters:
    `database` - the target database
  Returns:
    the Hibernate database dialect class, or `null`if none found``

### getJpaDialect

    public JpaDialect getJpaDialect()

  Description copied from interface: `JpaVendorAdapter`
  Return the vendor-specific JpaDialect implementation for this provider, or `null` if there is none.

  Specified by:
    `getJpaDialect` in interface `JpaVendorAdapter`
  Overrides:
    `getJpaDialect` in class `AbstractJpaVendorAdapter`

### getEntityManagerFactoryInterface

    public Class<? extends javax.persistence.EntityManagerFactory> getEntityManagerFactoryInterface()

  Description copied from interface: `JpaVendorAdapter`
  Return the vendor-specific EntityManagerFactory interface that the EntityManagerFactory proxy is supposed to implement.

  If the provider does not offer any EntityManagerFactory extensions, the adapter should simply return the standard `EntityManagerFactory` class here.

  Specified by:
    `getEntityManagerFactoryInterface` in interface `JpaVendorAdapter`
  Overrides:
    `getEntityManagerFactoryInterface` in class `AbstractJpaVendorAdapter`

### getEntityManagerInterface

    public Class<? extends javax.persistence.EntityManager> getEntityManagerInterface()

  Description copied from interface: `JpaVendorAdapter`
  Return the vendor-specific EntityManager interface that this provider's EntityManagers will implement.

  If the provider does not offer any EntityManager extensions, the adapter should simply return the standard `EntityManager` class here.

  Specified by:
    `getEntityManagerInterface` in interface `JpaVendorAdapter`
  Overrides:
    `getEntityManagerInterface` in class `AbstractJpaVendorAdapter`
