我正在尝试使用 post.jar 来索引包含 pdf 文件的文件夹。我已经添加了请求处理程序，但我在启动时遇到错误。

看起来，它可能是版本冲突或重复的类加载，因此不被识别为 SolrRequestHandler。只是一个想法。

我在带有 iis 的 windows 2008 r2 服务器上运行 solr 3.4。

配置：

<lib dir="C:\ColdFusion10\cfusion\jetty\solr\contrib\extraction\lib" />
<lib dir="C:\ColdFusion10\cfusion\jetty\solr\dist\" regex="apache-solr-cell-\d.*\.jar" />
<lib dir="C:\ColdFusion10\cfusion\jetty\solr\dist\" regex="apache-solr-dataimporthandler-\d.*\.jar" />


<requestDispatcher handleSelect="true" >
    <requestParsers enableRemoteStreaming="true" multipartUploadLimitInKB="15000000" />
</requestDispatcher>
<requestHandler name="/update/extract" class="org.apache.solr.handler.extraction.ExtractingRequestHandler">
    <lst name="defaults">
      <str name="fmap.Last-Modified">last_modified</str>
      <str name="uprefix">ignored_</str>
    </lst>
    <!-- Optional. Specify one or more date formats to parse.  See DateUtil.DEFAULT_DATE_FORMATS for default date formats -->
    <lst name="date.formats">
      <str>dd.MM.yyyy HH:mm:ss</str>
    </lst>
</requestHandler>

它肯定看起来像图书馆冲突。你的系统上有两个版本的 Solr 吗？我将首先将指令中的相对路径更改为绝对路径，然后看看会发生什么。也许你的“主”目录不是你想象的那样。或者 LaunchAnywhere 对类路径做了一些奇怪的事情。
