我在尝试使用 DataImportHandler 从 MySQL 导入位置数据时遇到问题。我的子实体之一的查询是：
SELECT [...] AS data, AsText(data_geo) AS data_geo FROM [table] WHERE [conditions]
我已经运行了查询并验证了输出看起来正确：
'128 Wall St, New Haven, CT 06511, USA', 'POINT(-72.92847010000003 41.31160920000001)'
但是，当我尝试运行导入时，出现以下异常：
SolrWriter.upload(73) | Error creating document : SolrInputDocument(fields: [[...], data=128 Wall St, New Haven, CT 06511, USA, data_geo=[B@23bcddc0, _version_=1573858358394355712])

schema.xml 中的相关配置为：
<field name="data_geo" type="location_rpt" indexed="true" stored="true" multiValued="false" />
<fieldType name="location_rpt" class="solr.SpatialRecursivePrefixTreeFieldType"
spatialContextFactory="com.spatial4j.core.context.jts.JtsSpatialContextFactory"
autoIndex="true"
geo="true"
distErrPct="0.025"
maxDistErr="0.001"

我正在运行 Solr 5.2.1
知道为什么它尝试使用似乎是 Java 对象散列的东西来导入地理字段吗？
谢谢！
