Simple attributes (Boolean, Integer
etc.) can be initialized in the declaration of the corresponding field of an entity class, for example:
public class User extends StandardEntity {
...
@Column(name = "ACTIVE")
protected Boolean active = true;
...
}
Additionally, a specific initialization method with a
@PostConstruct annotation can be created in the entity
class. In this case, any global infrastructure interfaces and
beans can be invoked during initialization, for example:
public class MyEntity extends StandardEntity {
...
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "USER_ID")
protected User creator;
...
@PostConstruct
protected void init() {
setCreator(AppBeans.get(UserSessionSource.class).getUserSession().getUser());
}
}
