Solr DataImportHandler與地理區域問題

Question

我遇到了一個問題，試圖使用DataImportHandler從MySQL導入位置數據。用於我的子實體的一個查詢：

SELECT [...] AS data, AsText(data_geo) AS data_geo FROM [table] WHERE [conditions] 

我已經運行的查詢和核實輸出看上去是正確的：

'128 Wall St, New Haven, CT 06511, USA', 'POINT(-72.92847010000003 41.31160920000001)' 

然而，當我嘗試運行的進口，我得到的以下情況除外：

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中的相關配置爲：

<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" 
     distanceUnits="kilometers" /> 

我正在運行Solr 5.2.1

任何想法爲什麼它試圖使用什麼似乎是Java對象哈希導入地理領域？

謝謝！

我發現Solr的FAQ這裏的解決方案：

https://wiki.apache.org/solr/DataImportHandlerFaq#line-92

我不得不AsText的輸出轉換爲CHAR，儘管這DOC給出了其他兩種解決方案也是如此。
