Neo4j-节点的即时负载动态关系

我问了一个相关的问题。我发现正常关系实体的一切都很顺利，比如：

@RelationshipEntity(type="REL")
public class Rel {

    @GraphId
    private Long id;
    @Fetch
    @StartNode
    private User start;
    @Fetch
    @EndNode
    private User end;

    public Rel(){}
    public Rel(User start, User end) {
        this.start = start;
        this.end = end;
    }
}

但是，如果我添加一个动态关系类型，我就不能急切地加载关系

@RelationshipEntity(type="REL")
public class Rel {

    @GraphId
    private Long id;
    @Fetch
    @StartNode
    private User start;
    @Fetch
    @EndNode
    private User end;

    // define dynamic relationship type
    // which cause the issue!!!!
    @RelationshipType
    private String type;

    public Rel(){}
    public Rel(User start, User end, String type) {
        this.start = start;
        this.end = end;
        this.type = type;
    }
}

问题是什么，如何解决

欢迎提供任何帮助或建议。提前谢谢

Iterable rel=template.getRelationshipsBetween（user，client，UserRelationEntity.class，RelTypes.client.name（））；
 Iterable<UserRelationEntity> rel = template.getRelationshipsBetween(user, client, UserRelationEntity.class, RelTypes.CLIENT.name());
