我现在正在尝试从 pdf 索引数据，并且我从 Solr 得到以下响应：

<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<lst name="initArgs">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</lst>
<str name="command">full-import</str>
<str name="status">idle</str>
<str name="importResponse"/>
<lst name="statusMessages">
<str name="Time Elapsed">0:0:1.236</str>
<str name="Total Requests made to DataSource">0</str>
<str name="Total Rows Fetched">1</str>
<str name="Total Documents Processed">0</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2012-05-11 15:45:01</str>
<str name="">Indexing failed. Rolled back all changes.</str>
<str name="Rolledback">2012-05-11 15:45:01</str></lst><str name="WARNING">This response format is experimental.  It is likely to change in the future.</str>
</response>

显示此的日志文件：

配置文件如下所示： data-config.xml：

<?xml version="1.0" encoding="utf-8"?>

<dataConfig>
<dataSource type="BinFileDataSource" name="binary" />
    <document>
        <entity name="f" dataSource="binary" rootEntity="false" processor="FileListEntityProcessor" baseDir="C:\solr\solr\docu" fileName=".*pdf" recursive="true">
            <entity name="tika" processor="TikaEntityProcessor" url="${f.fileAbsolutePath}" format="text">
                <field column="id" name="id" meta="true" />
                <field column="fake_id" name="fake_id" />
                <field column="model" name="model" meta="true" />
                <field column="text" name="biog" />
            </entity>
        </entity>
    </document>

</dataConfig>

架构.xml：

<fields>
<field  name="id" type="string" indexed="true" stored="true" /> 
  <field  name="fake_id" type="string" indexed="true" stored="true" /> 
  <field  name="model" type="text_en" indexed="true" stored="true"  />
  <field  name="firstname" type="text_en" indexed="true" stored="true"/>
  <field  name="lastname" type="text_en" indexed="true" stored="true"/>
  <field  name="title" type="text_en" indexed="true" stored="true"/>
  <field  name="biog" type="text_en" indexed="true" stored="true"/>
  </fields>
<uniqueKey>fake_id</uniqueKey>
<defaultSearchField>biog</defaultSearchField>

最后，我拥有的“Tika”罐子是：

tika-core-1.0.jar 和 tika-parsers-1.0.jar

出了什么问题？谢谢

问题可能出在您的 data-config.xml 中，您在名为“f”的实体（带有 FileListEntityProcessor 处理器）上指定了 bin 文件 dataSource，而不是带有 TikaEntityProcessor 处理器的实体。我认为您可以尝试使用以下代码：

<?xml version="1.0" encoding="utf-8"?>
<dataConfig>
<dataSource type="BinFileDataSource" name="binary" />
    <document>
        <entity name="f" dataSource="null" rootEntity="false" processor="FileListEntityProcessor" baseDir="C:\solr\solr\docu" fileName=".*pdf" recursive="true">
            <entity name="tika" dataSource="binary" processor="TikaEntityProcessor" url="${f.fileAbsolutePath}" format="text">
                <field column="id" name="id" meta="true" />
                <field column="fake_id" name="fake_id" />
                <field column="model" name="model" meta="true" />
                <field column="text" name="biog" />
            </entity>
        </entity>
    </document>
</dataConfig>
