Question

这些是我尝试让delta导入处理程序工作的确切步骤。如果我能提供更多信息以帮助告诉我。我真的花了整个星期五晚上和今天这个，我扔掉了。我哪里出错了？

将此行添加到solrconfig：

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

然后我的data-config.xml看起来像这样：

<dataConfig>
  <dataSource type="FileDataSource" />
  <document>
    <entity 
      name="document" 
      processor="FileListEntityProcessor" 
      baseDir="/var/lib/data" 
      fileName=".*.xml$" 
      recursive="false" 
      rootEntity="false" 
      dataSource="null">
      <entity 
        processor="XPathEntityProcessor" 
        url="${document.fileAbsolutePath}" 
        useSolrAddSchema="true" 
        stream="true">
      </entity>
    </entity>
  </document>
</dataConfig>

然后在我的var / lib / data文件夹中，我有一个如下所示的data.xml文件：

<add>
<doc>
        <field name="id">123</field>
        <field name="description">This is my long description</field>
        <field name="company">Google</field>
        <field name="location_name">England</field>
        <field name="date">2007-12-31 22:29:59</field>
        <field name="source">Google</field>
        <field name="url">www.google.com</field>
        <field name="latlng">45.17614,45.17614</field>
</doc>
</add>

最后我运行了这个命令：

http://localhost:8080/solr/dataimport?command=delta-import&clean=false

我得到了这个结果（失败）：

<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<lst name="initArgs">
<lst name="defaults">

</lst>
</lst>
<str name="command">delta-import</str>
<str name="status">idle</str>
<str name="importResponse"/>
<lst name="statusMessages">

<str name="Total Documents Skipped">0</str>

<str name="Identifying Delta">2012-11-17 17:32:56</str>

<str name="Rolledback">2012-11-17 17:32:56</str>
</lst>
<str name="WARNING">

</str>
</response>

编辑：这是tomcat.log所说的：

查看Wiki：

唯一支持delta的EntityProcessor是SqlEntityProcessor！ XPathEntityProcessor还没有实现它。所以，遗憾的是，目前还没有对XML的delta支持。

无法获得Solr Delta Import Index
