Hey!
I try to test JPA features, so I currently try embedded Objects.
Entity User
@Entity
@SuppressWarnings("serial")
public class UserDO implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
protected Long id;
protected String nickname;
protected Email email;
protected Date lastLogin;
@Embedded
protected Adress adress;
public UserDO() {
}
....
}
I added a Adress Object.
@Embeddable
public class Adress {
protected String street;
protected String town;
...
}
Everything works fine and if i get a user and to user.getAdress() I
get the correct Object.
But when I need maybe 1000 Users... How is the best pratice...
currently I use this code:
List<UserDO> data = new ArrayList<UserDO>();
EntityManager em = EMF.get();
try {
Query query = em.createQuery( "SELECT e from " +
UserDO.class.getName() + " e" );
data.addAll( query.getResultList() );
for(UserDO u : data) {
u.getAdress();
}
} finally {
em.close();
}
Is there no way to say... load this object everytime I receive the
UserDO?
Thanks for help!
