I am trying to inject a Spring dependency into an JPA EntityListener. Here is my listener class:
@Configurable(autowire = Autowire.BY_TYPE, dependencyCheck = true)
public class PliListener {
@Autowired
private EvenementPliRepository evenementPliRepository;
@PostPersist
void onPostPersist(Pli pli) {
EvenementPli ev = new EvenementPli();
ev.setPli(pli);
ev.setDateCreation(new Date());
ev.setType(TypeEvenement.creation);
ev.setMessage("Création d'un pli");
System.out.println("evenementPliRepository: " + evenementPliRepository);
evenementPliRepository.save(ev);
}
}
Here is my Entity class:
@RooJavaBean
@RooToString
@RooJpaActiveRecord
@EntityListeners(PliListener.class)
public class Pli implements Serializable{
...
However, my dependency (i.e. evenementPliRepository
) is always null.
Can anyone please help?
A hack to inject dependencies on stateless beans, is to define the dependency as "static", create a setter method so that Spring can inject the dependency (assigning it to the static dependency).
Declare the dependency as static.
static private EvenementPliRepository evenementPliRepository;
Create a method so that Spring can inject it.
@Autowired
public void init(EvenementPliRepository evenementPliRepository)
{
MyListenerClass.evenementPliRepository = evenementPliRepository;
logger.info("Initializing with dependency ["+ evenementPliRepository +"]");
}
