春季靴Neo4j⚡️RXdto投影与关系不起作用

如何解决春季靴Neo4j⚡️RXdto投影与关系不起作用

我正在尝试使用DTO投影，以仅获得DTO的选定关系来优化Neo4j查询。

它在普通字段上正常工作，但是当我尝试与投影字段获得洞察关系时，它返回null。

这是我的Node实体

@Node("Subscription")
data class Subscription(
        @Id
        val id: UUID,@Relationship(type = "TO_PLAN",direction = OUTGOING)
        val plan: SubscriptionPlan?,@Relationship(type = "HAS_INVOICE",direction = OUTGOING)
        val invoice: Invoice?,@Relationship(type = "HAS_INSIGHT",direction = OUTGOING)
        val insight: Map<Insight,SubscriptionInsightsRelationship>,val status: SubscriptionStatuses,val isAutorenewal: Boolean,val insightsLastChange: LocalDateTime?,@CreatedDate
        val createdDate: LocalDateTime?,@LastModifiedDate
        val lastModifiedDate: LocalDateTime?
)

地图是如何在Neo4j⚡️RX中建立丰富关系的

这是我的投影DTO

data class RetrieveSubscriptionDto(
        val id: UUID,val insight: Map<Insight,SubscriptionInsightsRelationship>?,val lastModifiedDate: LocalDateTime?
)

这是存储库

interface SubscriptionRepository : ReactiveNeo4jRepository<Subscription,UUID> {
    fun findAllByIdisNotNull(): Flux<RetrieveSubscriptionDto>
}

此投影的返回值为

   {
        "id": "d3a816e5-d0be-4721-b34d-346b011b9757","insight": null,"status": "ACTIVE","lastModifiedDate": "2020-10-18T01:29:40.37691"
    }
