我正在尝试将UIMA与Solr集成。我正在遵循https://cwiki.apache.org/confluence/display/solr/UIMA+Integration中提到的步骤。但是当我尝试索引文档时,会在终端中抛出异常,并且还会记录solr日志中的错误跟踪。我一直试图解决一段时间,但无法为该问题找到合适的解决方案。 我已经包含了文件中提到的所有罐子。 我已经为API生成了有效的密钥。
分析字段:
<arr name="fields">
<str>content</str>
</arr>
内容字段属于字段类型text_general.It不是复制字段。该字段包含相应的文档内容。
<field name="content" type="text_general" indexed="true" termOffsets="true" stored="true" termPositions="true" termVectors="true" multiValued="true" required="true"/>

我一直在努力解决这个问题。
谢谢和问候。
