Question

我已经设置了我的solr_4.9.0安装与jetty一起运行，我正在尝试在solr索引中导入sqlite数据库。我在example \ solr \ collection1 \ conf \ solrconfig.xml中添加了一个额外的请求处理程序：

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

我在example \ solr \ collection1 \ conf \

下创建了一个文件db-data-config.xml

      <dataConfig>
      <dataSource driver="org.sqlite.JDBC"
       url="jdbc:sqlite:C:/..../BASE.db"
      user=""
      password="" />
      <document>
      <entity name="page" query="SELECT page_id, page_title from page">
      <field column="page_id" name="id" />
      <field column="page_title" name="name" />

      </entity>
      </document>
      </dataConfig>

我把sqlite-jdbc-3.7.2.jar放在example \ lib下我使用java -jar start.jar在cmd中运行，我有这个错误

解决：只需在solr：\ example \ solr \ lib下创建共享库并放置JDBC JAR和solr-dataimporthandler - * .jar jars。在solrconfig.xml中添加以下行：

     <lib dir="../lib" />
     <lib dir="../lib" regex="solr-dataimporthandler-.*\.jar" />

并且工作正常
