Mapping of nested classes collected under common label #2462
Description
Hello, team!
I have a question regarding inheritance again. For Example there is the following architecture:
@Getter
@Setter
@Node("Base")
public abstract class BaseClass {
@Id
private String uuid;
}
@Getter
@Setter
@Node("PetOwner")
public abstract class PetOwner extends BaseClass {
private String name;
@Relationship(type = "hasPet")
private List<Animal> pets;
}
@Node("Boy")
public class Boy extends PetOwner {
}
@Node("Girl")
public class Girl extends PetOwner {
}
@Getter
@Setter
@Node("Animal")
public abstract class Animal extends BaseClass {
private String name;
}
@Node("Cat")
public class Cat extends Animal {
}
@Node("Dog")
public class Dog extends Animal {
}
public interface BaseClassRepository extends Neo4jRepository<BaseClass, String> {
}
I have a use case when I need to get the collection of all entities that are subclassed from BaseClass. With OGM I was able to execute the following query and have everything mapped correctly.
MATCH (n:Base) RETURN n, [(n)-[r]->(b) | [r,b]]
But now the cypher response has increased significantly and not totally correct. It doesn't expect to cover even this simple inheritance scheme described in first code block.
Please take a look at my unit tests in the repository https://github.com/idun-corp/neo4j-test (Test PetOwnerNeo4jServiceTest.testGetAllWithRelations)
