我正在尝试将 UIMA 与 Solr 集成。我正在按照https://cwiki.apache.org/confluence/display/solr/UIMA+Integration中提到的步骤进行操作。但是当我尝试索引文档时，终端中会抛出异常，并且 solr 日志也​​会记录错误跟踪。我一直在尝试解决一段时间，但无法为该问题找到适当的解决方案。我已经包含了文档中提到的所有罐子。我已经为 API 生成了有效的密钥。

分析领域：

<arr name="fields">
          <str>content</str>
        </arr>

内容字段是字段类型 text_general。它不是复制字段。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"/>

solrconfig.xml：

我一直在为这个问题苦苦挣扎一段时间。

谢谢并恭祝安康。
