我正在尝试为我的 Apache Solr Core 测试 PDF 文档的索引。
我将必要的库添加到我的solrconfig.xml:
<lib dir="${solr.install.dir:../../..}/contrib/extraction/lib" regex=".*\.jar" />
<lib dir="${solr.install.dir:../../..}/dist/" regex="solr-cell-\d.*\.jar" />
我还添加了用于索引 PDF 文档的 RequestHandler:
<requestHandler name="/update/extract"
startup="lazy"
class="solr.extraction.ExtractingRequestHandler" >
<lst name="defaults">
<str name="lowernames">true</str>
<str name="fmap.content">_text_</str>
</lst>
</requestHandler>
之后，我重新启动了我的 Solr 服务器，然后尝试使用 curl 索引 PDF 文档:
curl 'http://localhost:8983/solr/test/update/extract?literal.id=doc1&commit=true' -F "myfile=@C:\Workspace\solr\solr-8.6.0\docs\pdf\test.pdf"
我希望文档被索引，但我却收到了 Error 500 java.lang.NoClassDefFoundError: org/eclipse/jetty/server/MultiParts:
> <html> <head> <meta http-equiv="Content-Type"
> content="text/html;charset=utf-8"/> <title>Error 500

有人有想法吗？
谢谢!
最佳答案
这是 Solr 8.6.0 和 Solr 8.6.1 的问题。参见 https://issues.apache.org/jira/browse/SOLR-14768
将 Solr 降级到 8.5.1 应该可以解决问题，直到问题在新的 Solr 版本中得到解决。
关于java - 将 PDF 文档索引到 Solr - 错误 500 java.lang.NoClassDefFoundError : org/eclipse/jetty/server/MultiParts，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/63070107/
