Currently, We're working on OGM base implementation. We like to move on SDN 6 But I face problem to update relationship by neo4jRepository. I mention domain model.
@Node
public class Activity {
@Id
@GeneratedValue
protected Long graphId;
private String guid;
@Relationship(type = "PARENT_OF", direction = Direction.OUTGOING)
private Set<Activity> children;
public void addChild(Activity child) {
this.children.add(child);
}
public void removeChild(Activity child) {
this.children.remove(child);
}
}
public interface ActivityReadRepository extends Neo4jRepository<Activity, Long>{
}
@Component
public class RunableClass implements CommandLineRunner{
@Autowired
ActivityRepository activityRepository;
@Override
public void run(String... args) throws Exception {
Activity parent = activityRepository.findByGuid("xxx-xxx-xxx-xxx-xxx")
Activity child = activityRepository.findByGuid("xxx-xxx-xxx-xxx-xxx1")
parent.removeChild(child);
activityRepository.save(parent);
}
}
After used save() Method, All Child `PARENT_OF` relationship will be removed. That above code working fine in SDN+OGM, but it does not work on SDN 6.
