在使用自定义的AttributeConverter for Neo4j时获取Neo.ClientError.Statement.TypeError Spring Boot JPA

我有一个与Spring Data Neo4j（v5.0.0RC2），Neo4j（v3.2.1）和Neo4j OGM（v3.0.0）一起运行的Kotlin（v1.1.4）Spring Boot（v2.0.0.BUILD-SNAPSHOT）应用程序。

尝试对具有自定义AttributeConverter的字段使用自定义JPA @Query时收到以下错误。

这是我的转换器： 

 class ZonedDateTimeStringConverter : AttributeConverter { companion object { private val DATE_TIME_FORMAT = DateTimeFormatter.ISO_OFFSET_DATE_TIME } override fun toGraphProperty(value: ZonedDateTime?): String? = when (value) { null -> null else -> DATE_TIME_FORMAT.format(value) } override fun toEntityAttribute(value: String?): ZonedDateTime? = when (value) { null -> null else -> ZonedDateTime.parse(value, DATE_TIME_FORMAT) } }

我在这里有一个关系实体： 

 @RelationshipEntity(type = "PART_OF") data class PartOf( /* * @GraphId, @StartNode, @EndNode defined here) */ @Convert(ZonedDateTimeStringConverter::class) var sinceDate: ZonedDateTime? = null )

我的JPA查询如下： 

 @Query("MATCH (s:EntityOne {identifier: {entityOneIdentifier}})" + " MATCH (v:EntityTwo {identifier: {entitiyTwoIdentifier}})" + " CREATE (v)-[:PART_OF {createDate: {createDate}, sinceDate: {sinceDate}, active: {active}}]->(s) " + " RETURN count(s) > 0") fun createPartOfRelationship(@Param("entityOneIdentifier") entityOneId: Long, @Param("entityTwoIdentifier") entityTwoId: Long, @Param("createDate") createDate: ZonedDateTime, @Param("sinceDate") sinceDate: ZonedDateTime, @Param("active") active: Boolean): Boolean

在线查看Neo4j参考资料的Spring数据，看起来我已经掌握了一切。 OGM正确地看到了转换器（我能够调试，并看到类中的静态companion object正在创建/命中。

所以，我认为Spring Data可能需要了解转换器。 所以，根据文档，我在我的spring配置中添加了一个ConversionService 。 

 @Bean fun conversionService(@Autowired sessionFactory: SessionFactory): ConversionService = MetaDataDrivenConversionService(sessionFactory.metaData())

这使用java.util.Date工作，就像Spring Data Neo4j文档说的那样（它的自动配置）在这里陈述了： http : //docs.spring.io/spring-data/neo4j/docs/4.0.0.RELEASE/参考/ HTML /＃reference_programming-model_conversion

有没有人有任何建议尝试或为什么这可能会发生？

这样的参数是不可能的 

 @Param("createDate") createDate: ZonedDateTime

在@Query注释的存储库方法中。

在这种情况下，目标types是String ，但可以是Integer ， Double等。并且查询将是相同的 – SDN不知道您需要转换的types，因此您需要执行转换以更正types自己（用于查询参数）。
