Since JPA 2.2, {{AttributeConverter}}-s should support CDI injection (see also [ HHH-12135 ] ). This doesn't seem to work when I rely on the converter being auto-applied, like this:
{code:java}
@Converter(autoApply = true)
public class MyAttributeConverter implements AttributeConverter<MyAttribute, String> {
@Inject
private MyUtils utils;
...
}
@Entity
public class MyEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
private MyAttribute myAttribute;
...
}
{code}
This is basically _Example 2: Auto-apply conversion of a basic attribute_ from the javadoc of {{@javax.persistence.Convert}}, so there should be nothing wrong with it. Yet, the {{utils}} field in {{MyAttributeConverter}} is {{null}} when the converter is invoked.
However, if I apply the converter explicitly:
{code:java}
@Convert(converter = MyAttributeConverter.class)
private MyAttribute myAttribute;
{code}
then it works just fine.
I'm no expert on JPA or CDI, but I believe auto-applied converters should support CDI as well.
As a reproducer, I'm attaching a simple Maven project which produces a WAR. I then deploy the WAR into WildFly 18.0.0.Final, which includes Hibernate ORM 5.3.12.Final (a reasonably up-to-date version). |
