entityStateFactory not set when saving from within @PostConstruct

[marcogerber]

Hello everybody

When I try to call save(MyEntity) on the MyEntityRepository as follows,

@NodeEntity
public class MyEntity {
  //setter and getter for a property called 'name'
}

public class MyEntityRepository extends GraphRepository<MyEntity> {
}

public class DbInitialization {
 @Autowired
 private MyEntityRepository repository;
 
 @PostConstruct
 public void initDb() {
  MyEntity entity = MyEntity.newInstance();
  entity.setName("foo");
  repository.save(entity);
 }
}

... I run into the following error:

org.springframework.data.neo4j.support.node.Neo4jNodeBacking      entityStateFactory not set, not creating accessors for class x.y.MyEntity

The bean DbInitialization is getting managed by the same application context as the SDG setup (config and repositories). I also autowire the graph repository into the bean DbInitialization to make sure that the dependencies should be resolved correctly by the spring context.
I also use aspectj compile time weaving.

Here's the complete stack trace:

I'm wondering why this happens in a @PostConstruct method. What am I doing wrong?

Thanks,

Hi Marco,
I ran into the same issue.
Did you find any solution for that?

As the aspects are also set up with the spring context you might have to declare the dependency in your bean on these beans:

* neo4jNodeBacking and neo4jRelationshipBacking (the aspects)

the following dependencies should be resolved automatically, it might be necessary to add them too

* nodeEntityStateFactory, relationshipEntityStateFactory
