How do I inject CDI beans into Custom Entity Classes?

[firepod]

We use Cassandra (and the DataStax driver) to store our entities. As such we have a custom entity service that creates new instances of our entity classes when it retrieves data from Cassandra.

I also need to inject services into my entity classes using CDI. How do I do this? When I simply at the @Inject annotation, it never gets injected.

public class Customer{

    @Inject
    private Event<DeactivationEvent> events;

    private String uid;

    public void setUid(String uid){
        this.uid = uid;
    }

    public String getUid(){
        return this.uid;
    }

    public void deactivate(){
        events.fire( new DeactivationEvent() );
    }

}


public CassandraEntityService{

    public Customer findCustomer(String uid){

        ...whatever lookup logic...
        Customer customer = new Customer();
    
        customer.setUid(..)
        customer.set...
    
        return customer;

    }

}

For reference, I'm using JBoss/Wildfly 8.1.

Thanks!

Hi there, your problem is that you create the entity via new operator so CDI is not managing your entity...i can see two options:

1. @Inject the Custumer so CDI can manage it which i think is not what you want
2. or you can fire the event programactly like below:

public void deactivate(){ 
       BeanManager bm =  CDI.current().getBeanManager();
       bm.fireEvent( new DeactivationEvent() ); 
    }

if you use CDI 1.0 you have to lookup BeanManager via jndi, something like:

BeanManager bm =  return (BeanManager) InitialContext.doLookup("java:comp/BeanManager");

I hope it helps.
