英文:
Index PDF Documents to Solr - Error 500 java.lang.NoClassDefFoundError: org/eclipse/jetty/server/MultiParts
问题
我正在尝试将PDF文档的索引添加到我的Apache Solr核心。
我已经在我的solrconfig.xml中添加了必要的库：
<lib dir="${solr.install.dir:../../..}/contrib/extraction/lib" regex=".*\.jar" />
<lib dir="${solr.install.dir:../../..}/dist/" regex="solr-cell-\d.*\.jar" />
我还为索引PDF文档添加了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Solr服务器，然后尝试使用curl来索引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"
我期望文档被索引，但实际上我收到了一个Error 500 java.lang.NoClassDefFoundError: org/eclipse/jetty/server/MultiParts的错误。

I'm trying to test an index of PDF documents to my Apache Solr Core.
I found the following instruction:
https://lucene.apache.org/solr/guide/8_0/uploading-data-with-solr-cell-using-apache-tika.html#configuring-the-extractingrequesthandler-in-solrconfig-xml
I added the neccessary **libraries** to my ```solrconfig.xml```:
<lib dir="${solr.install.dir:../../..}/contrib/extraction/lib" regex=".*\.jar" />
<lib dir="${solr.install.dir:../../..}/dist/" regex="solr-cell-\d.*\.jar" />
I also added the **RequestHandler** for indexing the PDF documents:
<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>
Afterwards, I restarted my Solr server and then tried to index a PDF document by using **curl**:
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"
I expected the document to be indexed, but instead I get an ```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

**得分**: 1
这是Solr 8.6.0和Solr 8.6.1的问题。请查看https://issues.apache.org/jira/browse/SOLR-14768
在问题在新的Solr版本中得到修复之前，将Solr降级至8.5.1版本应该可以解决这个问题。

It is an issue of Solr 8.6.0 and Solr 8.6.1. See https://issues.apache.org/jira/browse/SOLR-14768
Downgrading Solr to 8.5.1 should solve it until the issue is fixed in a new Solr release.
