Neo4j OGM doesn't read parent class fields of entity classes.
See original GitHub issueI have a common entity class as following.
import org.neo4j.ogm.annotation.GraphId;
public abstract class Entity {
@GraphId
private Long gid;
}
And my User entity class extends it.
class User extends Entity {
String uuid = Application.uuid()
String username
String password
}
But it cannot find gid
field in User class and for this reason it throws following exception:
org.neo4j.ogm.exception.MappingException: No identity field found for class: com.mayapp.domain.User

Hello Guys,
I was having the same problem, then i realized that my super class was in a package that wasn’t in the @EntityScan path. When I move my base class to any package that was in the @EntityScan path, it works.
Hope it helps. []s
Tried to reproduce with this. Can you check it out pls ?
