为多核设置 solr（可能相关也可能不相关）后，我有了一个工作测试系统。除了以下几行之外，solrconfig.xml居住在其中并且看起来基本上类似于多核的示例 solrconfig 文件：/solr-4.4.0/example/multicore/expertise/conf

<dataDir>/data/website_data/solr_cores/expertise</dataDir>

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
  <lst name="defaults">
    <str name="config">/data/website_data/solr_cores/expertise/data-config.xml</str>
  </lst>
</requestHandler>

因为我想要一个支持语言的 solr，所以我用一些选择处理程序（以前handleSelect是true）和一个新的updateRequestProcessorChain. 对 solrconf.xml 的更改如下所示：

<lib dir="${user.dir}/../contrib/analysis-extras/lucene-libs/" /><!-- relative to solrs 'example' directory -->
<lib dir="${user.dir}/../contrib/analysis-extras/lib/" />
<lib dir="${user.dir}/../dist/" regex="solr-langid-.*\.jar" />
<lib dir="${user.dir}/../contrib/langid/lib/" />    

<!-- required for language detection of input records -->
<updateRequestProcessorChain name="languages">
    <processor class="solr.LangDetectLanguageIdentifierUpdateProcessorFactory">
        <lst name="invariants">
            <str name="langid.fl">focus, expertise, platforms, partners, participation, additional</str>
            <str name="langid.whitelist">en,fr</str>
            <str name="langid.fallback">en</str>
            <str name="langid.langField">detectedlang</str>
            <bool name="langid.map">true</bool>
            <bool name="langid.map.keepOrig">false</bool>
        </lst>
    </processor>
    <processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>

<!-- uses language-detecting update.chain -->
<requestHandler name="/update" class="solr.UpdateRequestHandler">
    <lst name="invariants">
        <str name="update.chain">languages</str>
    </lst>
</requestHandler>

<requestDispatcher handleSelect="false"> <!-- ORIGINALLY FALSE -->
    <requestParsers enableRemoteStreaming="false" multipartUploadLimitInKB="2048" formdataUploadLimitInKB="2048" />

            participation:participation_fr, additional:additional_fr</str><!-- return lang-defined field when asked for generic field -->
    </lst>
</requestHandler>

现在我得到错误： Can't find resource '/data-config.xml' in classpath or 'multicore/expertise/conf/', cwd=/solr-4.4.0/example</str>

数据路径没有改变。data-config.xml 文件存在于它应该存在的位置，并且它的权限是正确的。为什么我原来的 solrconf.xml 可以找到 data-config.xml 而我的新的却找不到？

似乎 solrconfig.xml 中的语句顺序会有所不同。在这种情况下，任何<lib/>声明都必须在以下之一（或可能全部）之后：<luceneMatchVersion/>、<directoryFactory/ >、<dataDir>和。<schemaFactory/><updateHandler/>

最初，我的<lib>台词紧跟在开始<config>标签之后。这恰好是我正在使用的示例中放置它们的位置。所以也许 Java 只是出了问题，我的 solrconfig.xml 没有问题。

我希望这对其他人有帮助。
