Class EclipseLinkJpaVendorAdapter

java.lang.Object

org.springframework.orm.jpa.vendor.AbstractJpaVendorAdapter

org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter

All Implemented Interfaces:

JpaVendorAdapter

public class EclipseLinkJpaVendorAdapter
extends AbstractJpaVendorAdapter

JpaVendorAdapter implementation for Eclipse Persistence Services (EclipseLink). Developed and tested against EclipseLink 2.7; backwards-compatible with EclipseLink 2.5 and 2.6 at runtime.

Exposes EclipseLink'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 EclipseLink doesn't use package-level metadata.

Since:

2.5.2

EclipseLinkJpaVendorAdapter

public EclipseLinkJpaVendorAdapter()

Method Details

getPersistenceProvider

public PersistenceProvider getPersistenceProvider()

Description copied from interface: JpaVendorAdapter

Return the vendor-specific persistence provider.

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 accepted by the standard JPA bootstrap facilities, or an empty Map if there are no properties to expose

See Also:

• Persistence.createEntityManagerFactory(String, Map)

determineTargetDatabaseName

@Nullable
protected String determineTargetDatabaseName(Database database)

Determine the EclipseLink target database name for the given database.

Parameters:

database - the specified database

Returns:

the EclipseLink target database name, or null if none found

getJpaDialect

public EclipseLinkJpaDialect 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

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
