我今天才发现有一个新的 solr 版本（4.0 ALPHA）。所以，我试一试。设置后（在 Tomcat 下）我收到以下错误消息：此界面要求您激活管理请求处理程序，将以下配置添加到您的 solrconfig.xml：
<!-- Admin Handlers - This will register all the standard admin RequestHandlers. -->
<requestHandler name="/admin/" class="solr.admin.AdminHandlers" />
当我在 solrconfig.xml 中添加以下内容时弹出上述错误：
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
有人知道这是怎么回事吗？
先感谢您，
汤姆希腊
