Связь neo4j с данными Spring в сущности

Изображение У меня есть следующая сущность: Компания и Сотрудник с аннотацией neo4j данных spring:

Company.java

@NodeEntity(label = "Company")
public class Company {
    /**
     * Graph ID
     */
    @GraphId
    private Long id;
    ......
}

Employee.java

@NodeEntity(label = "Employee")
public class Employee {
    /**
     * Graph ID
     */
    @GraphId
    private Long id;
    ......
}

Тогда есть сущность отношения для этих сущностей:

@RelationshipEntity(type = "EMPLOY")
public class EmployRel {
    /**
     * Graph ID
     */
    @GraphId
    private Long id;
    @StartNode
    private Company company;
    @EndNode
    private Employee employee;
    ......
}

Итак, как сохранить ссылку в Company и Person?

Company.java

@Relationship(type = "EMPLOY", direction = Relationship.OUTGOING)
private Set<EmployRel> employeeRel = new HashSet<>();

OR

@Relationship(type = "EMPLOY", direction = Relationship.OUTGOING)
private Set<Employee> employee = new HashSet<>();

Person.java

@Relationship(type = "EMPLOY", direction = Relationship.INCOMING)
private Company company = new Company();

OR

@Relationship(type = "EMPLOY", direction = Relationship.OUTGOING)
private EmployRel employRel = new EmployRel();
