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.

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

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

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.

getJpaDialect

public JpaDialect getJpaDialect()

Description copied from interface: JpaVendorAdapter

Return the vendor-specific JpaDialect implementation for this provider, or null if there is none.
