Lazy/Eager loading/fetching in Neo4j/Spring-Data

Question

I have a simple setup and encountered a puzzling (at least for me) problem:

I have three pojos which are related to each other:

@NodeEntity
public cl         


        

Answer 1

Found the answer to all the questions myself:

@Iterable: yes, iterable can be used for readonly

@load on access: per default nothing is loaded. and automatic lazy loading is not available (at least as far as I can gather)

For the rest: When I need a relationship I either have to use @Fetch or use the neo4jtemplate.fetch method:

@NodeEntity
public class User {
    @GraphId Long nodeId;
    @RelatedTo(type="user", direction = Direction.INCOMING)
    private Iterable worker;
    @Fetch Unit currentUnit;

    String name;

}

class GetService {
  @Autowired private Neo4jTemplate template;

  public void doSomethingFunction() {
    User u = ....;
    // worker is not avaiable here

    template.fetch(u.worker);
    // do something with the worker
  }  
}
