document usage of multiple entity-managers

Key: DELTASPIKE-816

Project: DeltaSpike
Issue Type: Task
Components: Documentation
Affects Versions: 1.2.1
Reporter: Gerhard Petracek
Assignee: Ron Smeral
Fix For: 1.4.1
#1) application-managed via @PersistenceUnitName:
{code}
@ApplicationScoped
public class MultiEntityManagerProducer
{
@Inject
@PersistenceUnitName(puA)
private EntityManagerFactory emfA;
@Inject
@PersistenceUnitName(puB)
private EntityManagerFactory emfB;
@Produces
//e.g.: @RequestScoped
@DbA //custom qualifier annotation
public EntityManager createEntityManagerA()
{
return emfA.createEntityManager();
}
public void closeEmA(@Disposes @DbA EntityManager em)
{
em.close();
}
@Produces
//e.g.: @RequestScoped
@DbB //custom qualifier annotation
public EntityManager createEntityManagerB()
{
return emfB.createEntityManager();
}
public void closeEmB(@Disposes @DbB EntityManager em)
{
em.close();
}
}
{code}
or
#2) select from multiple container-managed em-managers based on the
InjectionPoint:
{code}
public class EntityManagerSelector
{
@PersistenceContext(unitName = firstDB)
private EntityManager firstEntityManager;
@PersistenceContext(unitName = secondDB)
private EntityManager secondEntityManager;
@Produces
protected EntityManager createEntityManager(InjectionPoint injectionPoint)
{
CustomQualifier customQualifier =
injectionPoint.getAnnotated().getAnnotation(CustomQualifier.class);
return selectEntityManager(customQualifier); //selects
firstEntityManager or secondEntityManager based on the details provided by
CustomQualifier
}
//...
}
{code}
or
#3) select from multiple container-managed em-managers based on a custom
context:
{code}
public class EntityManagerSelector
{
@PersistenceContext(unitName = firstDB)
private EntityManager firstEntityManager;
@PersistenceContext(unitName = secondDB)
private EntityManager secondEntityManager;
@Inject
private CustomDatabaseContext customDatabaseContext;
@Produces
protected EntityManager createEntityManager()
{
if (customDatabaseContext.usePrimaryDb()) {
