Interface JpaVendorAdapter

    • Method Detail

      • getPersistenceProvider

        PersistenceProvider getPersistenceProvider()
        Return the vendor-specific persistence provider.
      • getPersistenceProviderRootPackage

        @Nullable
        default java.lang.String getPersistenceProviderRootPackage()
        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.
        Since:
        2.5.2
      • getJpaPropertyMap

        default java.util.Map<java.lang.String,?> getJpaPropertyMap(PersistenceUnitInfo pui)
        Return a Map of vendor-specific JPA properties for the given persistence unit, 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.

        This implementation delegates to getJpaPropertyMap() for non-unit-dependent properties. Effectively, this PersistenceUnitInfo-based variant only needs to be implemented if there is an actual need to react to unit-specific characteristics such as the transaction type.

        NOTE: This variant will only be invoked in case of Java EE style container bootstrapping where a PersistenceUnitInfo is present (i.e. LocalContainerEntityManagerFactoryBean. In case of simple Java SE style bootstrapping via Persistence (i.e. LocalEntityManagerFactoryBean), the parameter-less getJpaPropertyMap() variant will be called directly.

        Parameters:
        pui - the PersistenceUnitInfo for the current persistence unit
        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
        Since:
        4.3.13

        PersistenceUnitInfo.getTransactionType(), PersistenceProvider.createContainerEntityManagerFactory(PersistenceUnitInfo, Map)
      • getJpaPropertyMap

        default java.util.Map<java.lang.String,?> getJpaPropertyMap()
        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 accepted by the standard JPA bootstrap facilities, or an empty Map if there are no properties to expose
        See Also:
        Persistence.createEntityManagerFactory(String, Map)
      • getJpaDialect

        @Nullable
        default JpaDialect getJpaDialect()
        Return the vendor-specific JpaDialect implementation for this provider, or null if there is none.
      • getEntityManagerFactoryInterface

        default java.lang.Class<? extends EntityManagerFactory> getEntityManagerFactoryInterface()
        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.

        Since:
        2.5.2
      • getEntityManagerInterface

        default java.lang.Class<? extends EntityManager> getEntityManagerInterface()
        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.

      • postProcessEntityManagerFactory

        default void postProcessEntityManagerFactory(EntityManagerFactory emf)
        Optional callback for post-processing the native EntityManagerFactory before active use.

        This can be used for triggering vendor-specific initialization processes. While this is not expected to be used for most providers, it is included here as a general extension hook.
