Class EntityManagerFactoryProducer

java.lang.Object

org.apache.deltaspike.jpa.impl.entitymanager.EntityManagerFactoryProducer

public class EntityManagerFactoryProducer
extends Object

Built in support for injecting EntityManagerFactories into own beans. The injection point must use the Qualifier PersistenceUnitName to express the desired persistence unit name.

The EntityManagerFactory for the given persistence unit will be produced as @Dependent scoped. It can be used to easily implement own EntityManagerProviders as shown in the following example which provides a producer according to the entitymanager-per-request design pattern:

 @ApplicationScoped
 public class SampleEntityManagerProducer {
   @Inject
   @PersistenceUnitName("testPersistenceUnit")
   private EntityManagerFactory emf;

   @Produces
   @RequestScoped
   public EntityManager createEntityManager() {
     return emf.createEntityManager();
   }

   public void closeEm(@Disposes EntityManager em) {
     em.close();
   }
 }
