Class OpenJpaVendorAdapter

java.lang.Object

org.springframework.orm.jpa.vendor.AbstractJpaVendorAdapter

org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter

All Implemented Interfaces:

JpaVendorAdapter

public class OpenJpaVendorAdapter
extends AbstractJpaVendorAdapter

JpaVendorAdapter implementation for Apache OpenJPA. Developed and tested against OpenJPA 2.2.

Exposes OpenJPA's persistence provider and EntityManager extension interface, and adapts AbstractJpaVendorAdapter's common configuration settings. No support for the detection of annotated packages (through SmartPersistenceUnitInfo.getManagedPackages()) since OpenJPA doesn't use package-level metadata.

Since:

2.0

Constructor Detail

OpenJpaVendorAdapter

public OpenJpaVendorAdapter()

Method Detail

getPersistenceProvider

public 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

Persistence.createEntityManagerFactory(String, java.util.Map), PersistenceProvider.createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo, java.util.Map)

determineDatabaseDictionary

protected String determineDatabaseDictionary(Database database)

Determine the OpenJPA database dictionary name for the given database.

Parameters:

database - the specified database

Returns:

the OpenJPA database dictionary name, or null if none found

getJpaDialect

public OpenJpaDialect 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 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 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
