SOLR DataImport错误“无法执行查询” [英] SOLR DataImport Error "Unable to Execute Query"

问题描述

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协作。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

I have a website running on an Amazon EC2 Instance, and I'm trying to get Solr to interface and work with the database I'm using. I'm able to use the admin interface and have gotten the example xml files indexed, but whenever I try to import one of my database tables, I get the error

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。

Here's my data-config.xml file. I also added the dataimporthandler to the solrconfig.xml file.

<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。

Any idea why this is happening? And just let me know if I need to clarify anything.

所以我更改了网址并删除了'http：//'并且该错误似乎消失了。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。

So I changed the url a bit and removed the 'http://' and that error seemed to go away. However none of the information seems to be searchable through the admin. There are now a few files in the data directory (_1.fnm, _1.frq,...). Here is what solr prints to the log.

推荐答案

我想问题出在 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上.mysite.com，然后使用 url =jdbc：mysql：//www.mysite.com/mydb

I think the problem is with the url parameter. If the MySQL database is on the same machine, then use url="jdbc:mysql://localhost/mydb" If its on www.mysite.com, then use url="jdbc:mysql://www.mysite.com/mydb"
