JPA 2.1: CDI Support

JPA 2.1: CDI Support
In JPA 2.0 or the early version, you can not @Inject a CDI bean into JPA facilities.
Utilize with Apache CODI or JBoss Seam 3, @Inject is supported in Entity Listener classes.
Luckily, JPA 2.1 bring native CDI support.
Have a look at the PostListener in the jpa-converter example.

public class PostListener {

    @Inject
    Logger log;

    @PrePersist
    public void prePresist(Object o) {
        log.info("call prePresist");
        if (o instanceof Post) {
            Post post = (Post) o;
            final Date created = new Date();
            post.setCreated(created);
            post.setLastModified(created);
        }
    }

    @PreUpdate
    public void preUpdate(Object o) {
        log.info("call preUpdate");
        if (o instanceof Post) {
            Post post = (Post) o;
            post.setLastModified(new Date());
        }
    }
}

In this example, a CDI managed Logger bean war injected into PostListener and was use for tracking the persisting and updating of the Post entity.

@EntityListeners(PostListener.class)
public class Post implements Serializable {...}

In the Post entity class, apply this EntityListener. When run this project on Glassfish 4, the related log will be displayed in the NetBeans Console view.
But unfortunately, when you try to add the same lifecycle callbacks in the @Entity class, the @Inject annotation does not work, neither in the new introduced @Converter class.
