我有一个在 Amazon EC2 实例上运行的网站，我正在尝试让 Solr 与我正在使用的数据库进行交互和使用。我能够使用管理界面并已将示例 xml 文件编入索引，但每当我尝试导入我的数据库表之一时，我都会收到错误

SEVERE: Exception while processing: gamelydb document : SolrInputDocument[{}]:org.apache.solr.handler.dataimport.DataImportHandlerException:
 Unable to execute query: SELECT * FROM league Processing Document # 1

这是我的 data-config.xml 文件。我还将 dataimporthandler 添加到 solrconfig.xml 文件中。

<dataConfig>
  <dataSource type="JdbcDataSource"
              driver="com.mysql.jdbc.Driver"
              url="jdbc:mysql://www.mysite.com/mydb"
              user="root"
              password="mypassword"/>
  <document>
    <entity name="mydb"
            query="SELECT * FROM league">
       <field column="id" name="id" />
       <field column="leaguename" name="leaguename" />
    </entity>
  </document>
</dataConfig>

知道为什么会这样吗？如果我需要澄清任何事情，请告诉我。

所以我稍微更改了 url 并删除了“http://”，该错误似乎消失了。但是，似乎无法通过管理员搜索任何信息。数据目录中现在有一些文件(_1.fnm、_1.frq、...)。这是 solr 打印到日志的内容。

最佳答案

我认为问题出在 url 参数上。 如果MySQL数据库在同一台机器上，那么使用url="jdbc:mysql://localhost/mydb" 如果它在 www.mysite.com 上，则使用 url="jdbc:mysql://www.mysite.com/mydb"

此外，您的日志文件可能包含有关错误的更多详细信息 - 请仔细阅读日志并在此处发布适当的条目。
