How to configure Entity Manager dependency injection on Jersey - rest

Question

I have a Java web application running on Tomcat 9.
It uses the tools: Primefaces 10, JSF 2, CDI, EclipseLink.
This application is modularized as follows:
model
dao
service
managedBean
web
I created another modules
microservice
restful
where the "restful module" is the jsersey restful webservice.
I incorporate this webservice with the "service", "dao" and "model" modules using dependency injection (CDI) binding through this class
public class MyApplicationBinder extends AbstractBinder {
// mapping dependency injection with jersey
#Override
protected void configure() {
//bind(MicroserviceDataImpl.class).to(MicroserviceDataImpl.class); // concrete class
bind(SequenceRuleImpl.class).to(SequenceRule.class); // class implementing interface
bind(CaracteristicaMS.class).to(new TypeLiteral<Microservice<CaracteristicaDTO>>(){}); // classe implementing interface with generics
bind(MSCaracteristicaDaoImpl.class).to(new TypeLiteral<Dao<Caracteristica>>(){}).qualifiedBy(new Qualifier.DaoMSCaracteristica()); // class implementing interface with generics and qualifier
}
}
My qualifier
public class Qualifier {
public static class DaoMSCaracteristica extends AnnotationLiteral<DaoType> implements DaoType {
#Override
public TipoClasse value() {
return TipoClasse.CARACTERISTICA;
}
}
}
My resource
#RequestScoped #Path("/caracteristica")
public class CaracteristicaRestful {
#Inject
private Microservice<CaracteristicaDTO> cms;
// other attributes and methods
}
My microservice class
#Dependent
public class CaracteristicaMS implements Microservice<CaracteristicaDTO>, Serializable {
#Inject #DaoType(TipoClasse.CARACTERISTICA)
private Dao<Caracteristica> cd;
// others attributes and methods
}
My dao class
#Dependent #Default #DaoType(value = TipoClasse.CARACTERISTICA)
public class CaracteristicaDaoImpl extends AbsDao<Caracteristica> implements Dao<Caracteristica>, Serializable {
#NotNull #Inject #PersistenceUnitNameType(CADMAT_PU)
EntityManagerFactory emf;
// others attributes and methods
}
My Entity Manager factory provider
#ApplicationScoped
public class EMFProvider {
public static final EntityManagerFactory EMF_CADMAT = Persistence.createEntityManagerFactory(CADMAT_PU);
public static final EntityManagerFactory EMF_SIAFNET = Persistence.createEntityManagerFactory(SIAFEM_PU);
#Produces #Dependent #PersistenceUnitNameType(SIAFEM_PU)
public EntityManagerFactory getEMF_SIAFNET() {
return EMF_SIAFNET;
}
#Dependent #PersistenceUnitNameType(SIAFEM_PU)
public void closeENF_SIAFNET(#Disposes #PersistenceUnitNameType(SIAFEM_PU) EntityManagerFactory emf) {
if (emf != null && emf.isOpen()) {
Logger.getAnonymousLogger().log(Level.INFO, "***** closing em {0}", emf);
emf.close();
}
}
#Produces #ApplicationScoped #PersistenceUnitNameType(CADMAT_PU)
public EntityManagerFactory getEMF_CADMAT() {
return EMF_CADMAT;
}
#Produces #Dependent #PersistenceUnitNameType(CADMAT_PU)
public EntityManager getEM() {
EntityManager em = EMF_CADMAT.createEntityManager();
Logger.getAnonymousLogger().log(Level.INFO, "***** creating em {0}", em);
return em;
}
#ApplicationScoped #PersistenceUnitNameType(CADMAT_PU)
public void close(#Disposes #PersistenceUnitNameType(CADMAT_PU) EntityManagerFactory emf) {
if (emf != null && emf.isOpen()) {
Logger.getAnonymousLogger().log(Level.INFO, "***** closing em {0}", emf);
emf.close();
}
}
#Dependent #PersistenceUnitNameType(CADMAT_PU)
public void close(#Disposes #PersistenceUnitNameType(CADMAT_PU) EntityManager em) {
if (em != null && em.isOpen()) {
Logger.getAnonymousLogger().log(Level.INFO, "***** closing em {0}", em);
em.close();
}
}
}
My transactional interceptor
#Interceptor #TransactionType
public class TransactionalInterceptor {
#AroundInvoke
public Object transactional(InvocationContext ctx) throws Exception {
EntityManager em = null;
Field field = null;
try {
field = ctx.getMethod().getDeclaringClass().getDeclaredField("em");
} catch (NoSuchFieldException e1) {
try {
field = ctx.getMethod().getDeclaringClass().getSuperclass().getDeclaredField("em");
} catch (NoSuchFieldException e2) {
throw new IllegalStateException("invalid interceptor configuration for " + ctx.getMethod().getDeclaringClass());
}
}
field.setAccessible(true);
em = (EntityManager)field.get(ctx.getTarget());
if (em == null) throw new IllegalStateException("*** no em for transaction");
Logger.getAnonymousLogger().info("*** transaction em " + em);
Dao.begin(em);
Object obj = ctx.proceed();
Dao.commit(em);
return obj;
}
}
My interface annotation classes
#Qualifier #Retention(RetentionPolicy.RUNTIME) #Target({TYPE, METHOD, FIELD, PARAMETER})
public #interface DaoType {
public TipoClasse value();
}
#Qualifier #Retention(RetentionPolicy.RUNTIME) #Target({TYPE, METHOD, FIELD, PARAMETER})
public #interface PersistenceUnitNameType {
public String value();
}
Is there a way to bind my EntityManager using this structure?
