在为 Neo4j Spring Boot JPA 使用自定义 AttributeConverter 时获取 Neo.ClientError.Statement.TypeError
Getting a Neo.ClientError.Statement.TypeError when using custom AttributeConverter for Neo4j Spring Boot JPA
我有一个 Kotlin (v1.1.4) Spring Boot (v2.0.0.BUILD-SNAPSHOT) 应用程序 运行 Spring Data Neo4j (v5.0.0 RC2)、Neo4j (v3.2.1) 和 Neo4j OGM (v3.0.0)。
我在尝试将自定义 JPA @Query 与具有自定义 AttributeConverter.
的字段一起使用时收到以下错误

这是我的转换器：
class ZonedDateTimeStringConverter : AttributeConverter<ZonedDateTime, String> {
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
查看 Spring 在线 Neo4j 参考数据，看起来我已经准备好了一切。 OGM 正确地看到转换器（我能够调试并看到正在创建/命中 class 内部的静态 companion object。
所以，我假设 Spring 数据可能需要了解转换器。因此，根据文档，我在 spring 配置中添加了一个 ConversionService。
@Bean
fun conversionService(@Autowired sessionFactory: SessionFactory): ConversionService =
MetaDataDrivenConversionService(sessionFactory.metaData())
使用 java.util.Date 确实有效，就像 Spring Data Neo4j 文档说它应该（它的自动配置）在这里说明：http://docs.spring.io/spring-data/neo4j/docs/4.0.0.RELEASE/reference/html/#reference_programming-model_conversion
有没有人有任何尝试或为什么会发生这种情况的建议？
不可能有这样的参数
@Param("createDate") createDate: ZonedDateTime
在 @Query 注释存储库方法中。
本例中的目标类型是 String，但也可能是 Integer、Double 等。查询是相同的——SDN 不知道类型您需要转换为，因此您需要自己进行转换以更正类型（对于查询参数）。
我有一个 Kotlin (v1.1.4) Spring Boot (v2.0.0.BUILD-SNAPSHOT) 应用程序 运行 Spring Data Neo4j (v5.0.0 RC2)、Neo4j (v3.2.1) 和 Neo4j OGM (v3.0.0)。
我在尝试将自定义 JPA @Query 与具有自定义 AttributeConverter.

这是我的转换器：
class ZonedDateTimeStringConverter : AttributeConverter<ZonedDateTime, String> {
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
查看 Spring 在线 Neo4j 参考数据，看起来我已经准备好了一切。 OGM 正确地看到转换器（我能够调试并看到正在创建/命中 class 内部的静态 companion object。
所以，我假设 Spring 数据可能需要了解转换器。因此，根据文档，我在 spring 配置中添加了一个 ConversionService。
@Bean
fun conversionService(@Autowired sessionFactory: SessionFactory): ConversionService =
MetaDataDrivenConversionService(sessionFactory.metaData())
使用 java.util.Date 确实有效，就像 Spring Data Neo4j 文档说它应该（它的自动配置）在这里说明：http://docs.spring.io/spring-data/neo4j/docs/4.0.0.RELEASE/reference/html/#reference_programming-model_conversion
有没有人有任何尝试或为什么会发生这种情况的建议？
不可能有这样的参数
@Param("createDate") createDate: ZonedDateTime
在 @Query 注释存储库方法中。
本例中的目标类型是 String，但也可能是 Integer、Double 等。查询是相同的——SDN 不知道类型您需要转换为，因此您需要自己进行转换以更正类型（对于查询参数）。
