我正在尝试使用DIH从SQL服务器导入数据。我遇到了异常。

请帮我解决这个问题并告诉我有没有其他方法可以在不使用DataImportHandler的情况下将数据索引到solr中，或者有没有办法使用任何C＃app或类似的东西将数据索引到solr？
提前致谢。
答案 0 :(得分：0)
将apache-solr-dataimporthandler-x.y.z。jar和apache-solr-dataimporthandler-extras-x.y.z.jar文件添加到Solr home的 lib 文件夹中，并在solrconfig.xml文件中配置lib目录。
索引数据的另一种方法是使用SolrSharp项目。
