使用spring数据neo4j节点存储库获取关系属性

Question

如果我们有一个像这样的公司节点，它使用OWNS关系链接到另一个节点(位置(。

@NodeEntity ("Company")
public class Company {
@Id
@Property
private String companyId;
@Property
private String partyId;
@Relationship (type = "OWNS", direction = Relationship . OUTGOING )
private Set<Location> ownedLocations;
}

自有关系

@RelationshipEntity (type = "OWNS")
public class Owns {
@Property
private String ownsProperty;
@StartNode
private Company company;
@EndNode
private Location location;
}

这是存储库

@Repository
public interface CompanyRepository extends Neo4jRepository<Company, String> {
@Query ("match (c:Company)-[x:OWNS]-(y) where c.partyId = $0 return c,x,y")
Stream<Company> getCompaniesWithRelationsByPartyId(final String partyId);
}

因此，当我运行此查询时，我只得到Company和Location实体，而没有OWNS ownsProperty。如何使用上述存储库获取关系属性？

注意：我不想使用@QueryResult

在此处输入代码

您必须将Owns关系实体定义为Company中关系的类型，如以下

@Relationship (type = "OWNS", direction = Relationship . OUTGOING )
private Set<Owns> ownedLocations;
