Class MergePersistenceUnitManager

java.lang.Object

org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager

org.broadleafcommerce.common.extensibility.jpa.MergePersistenceUnitManager

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.InitializingBean, org.springframework.context.ResourceLoaderAware, org.springframework.context.weaving.LoadTimeWeaverAware, org.springframework.orm.jpa.persistenceunit.PersistenceUnitManager

public class MergePersistenceUnitManager
extends org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager

Merges jars, class names and mapping file names from several persistence.xml files. The MergePersistenceUnitManager will continue to keep track of individual persistence unit names (including individual data sources). When a specific PersistenceUnitInfo is requested by unit name, the appropriate PersistenceUnitInfo is returned with modified jar files urls, class names and mapping file names that include the comprehensive collection of these values from all persistence.xml files.
