我有一个网站在亚马逊EC2实例上运行，我试图让Solr接口并使用我正在使用的数据库。我能使用管理界面，并已经得到了索引的示例XML文件，但每当我试图导入我的数据库表中的一个，我得到的错误SOLR DataImport错误“无法执行查询”
SEVERE: Exception while processing: gamelydb document : SolrInputDocument[{}]:org.apache.solr.handler.dataimport.DataImportHandlerException:
Unable to execute query: SELECT * FROM league Processing Document # 1
这是我的数据-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>
任何想法为什么会发生这种情况？只要让我知道我是否需要澄清任何事情。
所以我改变了网址，删除了'http：//'，那个错误似乎消失了。但是，没有任何信息似乎可以通过管理员搜索。数据目录中有几个文件（_1.fnm，_1.frq，...）。这是什么solr打印到日志。

编辑：如果你发现这里的东西downvotable，请让我知道，所以我可以修复它。
最有可能的原因是与Solr或Lucene无关。它与使用IPv6的Java相关。因此，'localhost'被解析为“:: 1”而不是127.0.0.1。哪些mysql无法识别。要强制Java使用IPv4（在Linux上），请使用：export _JAVA_OPTIONS =“ - Djava.net.preferIPv4Stack = true” –
