SOLR 数据导入错误“无法执行查询"

SOLR DataImport Error quot;Unable to Execute Queryquot;(SOLR 数据导入错误“无法执行查询)

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使用.我能够使用管理界面并已将示例 xml 文件编入索引，但是每当我尝试导入我的数据库表之一时，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.我还在 solrconfig.xml 文件中添加了 dataimporthandler.

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事情，请告诉我.

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

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.现在数据目录中有几个文件(_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

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

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"
