EAGER CDI with AttributeConverter error

jorcx.liu Jan 12, 2019 6:34 AM

Hi,

I want to load some configurable data from database when my application startup, so i use . javax.enterprise.inject.spi.Extension

BUT

When i use AttributeConverter with JPA, i got the following exception

Caused by: javax.persistence.PersistenceException: Error attempting to apply AttributeConverter

Hello,

the exception suggests that you are attempting to use BeanManager too early on.
What observer method in CDI extension do you use? I would expect this won't work until AfterDeploymentValidation.

Hi,Matej

Thank you for your reply.

Yes, i use AfterDeploymentValidation observer event. e.g.

public class EagerCDIExtension implements javax.enterprise.inject.spi.Extension {
    @SuppressWarnings("serial")
    public void validate(@Observes AfterDeploymentValidation event, BeanManager bm) {
        bm.getBeans(Object.class, new AnnotationLiteral<Eager>() {})
          .parallelStream()
          .filter(bean -> bean.getBeanClass().isAnnotationPresent(ApplicationScoped.class))
          .forEach(
              bean -> {
                  bm.getReference(bean, bean.getBeanClass(), bm.createCreationalContext(bean)).toString();
              }
          );
    }
}

What shoud i use if i want loading data from database after my application started?

It works when there is no AttributeConverter

This sounds more like a Hibernate bug, or a problem in integrating CDI and hibernate bootstrap.
I have found this Hibernate issue which seems spot on to what you are describing - [HHH-12912] NullPointerException when named query with a converter is compiled before CDI BeanManager is available using… (although I don't know if you are using WFLY).

The issue above has some workarounds mentioned, give it a spin.
Otherwise, I don't think you can do much from CDI side. Maybe look for some lifecycle event that comes even after CDI's AfterDeploymentValidation, perhaps some event coming from Hibernate that you could hook into? But I am really just guessing here.
