Class DefaultSelectorPersistenceAnnotationBeanPostProcessor

java.lang.Object

org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor

com.neurosys.dao.jpa.DefaultSelectorPersistenceAnnotationBeanPostProcessor

All Implemented Interfaces:

Serializable, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.config.DestructionAwareBeanPostProcessor, org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessor, org.springframework.beans.factory.support.MergedBeanDefinitionPostProcessor, org.springframework.core.Ordered, org.springframework.core.PriorityOrdered

public class DefaultSelectorPersistenceAnnotationBeanPostProcessor
extends org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor

When defining multiple EntityManagerFactorys in Spring, the PersistenceContext without unit name will cause problems, since base libraries assume a single PersistenceContext, this will cause all base libraries to throw a NoUniqueBeanDefinitionException that encounter a unitNameless EntityManager.

By defining an instance of this in Spring it will override the default behavior of PersistenceAnnotationBeanPostProcessor when searching a default, it will default to either the Spring bean id (using a default PersistenceContext) should prefix the factory name to it OR the first one defined in the configs.
