Neo4j - Eager为节点加载动态关系

Question

我问了一个相关的问题here。我发现像这样的普通关系实体一切正常：

@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;
    }
}

但如果我添加动态关系类型，我无法急切加载关系。

@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，以及如何解决？

欢迎任何帮助或建议。提前谢谢！

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