使用neo4j-ogm获取具有多个标签的节点

Question

我有一个图，其中某些节点可以具有多个标签

Canonical，JobTitle是赋予同一节点的标签（每个Canonical节点都是一个JobTitle节点，反之亦然）（名称为“主管”）

我的节点类定义如下

@NodeEntity(label="JobTitle")
public class JobTitle {
    @Id @GeneratedValue
    private Long id;

    private Integer count;
    private String name;
    private String name_lower;
    // other getter methods
}

@NodeEntity(label="Canonical")
public class CanonicalJobTitle extends JobTitle{

    private Integer depth;

    public Integer getDepth(){
        return depth;
    }
}

和我的nodeDAO类定义为

public class NodeDAO<T> {
    private static final int DEPTH_LIST = 0;
    private static final int DEPTH_ENTITY = 1;
    final Class<T> typeParameterClass;
    private Session session;

    public NodeDAO(Session session, Class<T> typeParameterClass) {
        this.session = session;
        this.typeParameterClass = typeParameterClass;
    }

    public Iterable<T> matchRaw(String query){
        return this.query(query);
    }
}

我正在尝试触发一个简单的查询，但出现以下错误

String query = "match (n:JobTitle{name_lower:\"supervisor\"}) return n";
// Both of the line below gives the same exception
//Iterable<CanonicalJobTitle> titles = CanonicalJobTitleNodeDAO.matchRaw(query);
Iterable<JobTitle> titles = JobTitleNodeDAO.matchRaw(query);

错误为AmbiguousBaseClassException-

[main] INFO org.neo4j.ogm.drivers.bolt.request.BoltRequest - Request: match (n:JobTitle{name_lower:"supervisor"}) return n with params {}
[main] WARN org.neo4j.ogm.session.Neo4jSession - Error executing query : Multiple classes found in type hierarchy that map to: [Canonical, JobTitle]. Rolling back transaction.

这是我对neo4j的Maven依赖项

        <groupId>org.neo4j</groupId>

一个人应该如何处理neo4j-ogm中的多标签节点？
