SOLR DataImport错误“无法执行查询”

标签： mysql search indexing solr

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。我能够使用管理界面并获得索引的示例xml文件，但每当我尝试导入我的一个数据库表时，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内容，请告诉我。

所以我稍微更改了网址并删除了'http：//'，这个错误似乎消失了。但是，没有任何信息似乎可以通过管理员进行搜索。现在数据目录中有一些文件（_1.fnm，_1.frq，...）。这是solr打印到日志的内容。

3 个答案:

答案 0 :(得分：2)

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" 如果在www.mysite.com上，请使用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 - 请仔细检查日志并在此处发布相应的条目。

答案 1 :(得分：2)

我遇到了类似的问题。我的数据库在同一台机器上。 在data-config.xml中，我更改了行：

url="jdbc:mysql://localhost/mydb"

到

url="jdbc:mysql://127.0.0.1/mydb"

然后事情奏效了。 Solr / Lucene的方式很奇怪！

答案 2 :(得分：1)

你可以尝试做以下麻烦：

  • 如果sqlDB安装在同一台计算机上，请使用url="jdbc:mysql://localhost:1433/mydb。
  • 检查Tomcat文件夹是否有错误（Catalina文件）。
  • 启用数据库级别的审核并检查其上的日志。
