spring – 具有相同类型的多个关系类

使用spring-data-neo4j,我想使用@RelationshipEntity(type =“OWNS”)创建两个类,将Person类链接到Pet和Car.

@RelationshipEntity(type="OWNS")
public class OwnsCar {  
    @Indexed
    private String name;

    @StartNode
    private Person person;

    @EndNode
    private Car car;
}

@RelationshipEntity(type="OWNS")
public class OwnsPet {
    @Indexed
    private String name;

    @EndNode
    private Person person;

    @StartNode
    private Pet pet;
}

这样可以正确保存到图形数据库,没有任何问题,因为我可以查询实际的节点和关系并查看它们的类型等.

但是当我尝试使用@RelatedTo(type =“OWNS”,elementClass = Pet.class)时,我得到一个类强制转换异常,或者在使用延迟初始化时,我得到的结果不正确.

@NodeEntity
public class Person {   
    @Indexed
    private String name;

    @RelatedTo(type="OWNS",direction=Direction.OUTGOING,elementClass=Pet.class)
    private Set

Person [nodeId=1,name=Nick,pets=[Car [nodeId=3,name=Thunderbird]],cars=[Car [nodeId=3,name=Thunderbird]]]
