我是solr的新手，我试图从mysql导入简单数据，但我找到的例子对我不起作用。
在solrconfig.xml我有
<?xml version="1.0" encoding="UTF-8" ?>
<config>
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
more stuffs..
并在data-config.xml
<dataConfig>
<dataSource
type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/test"
user="root"
password=""/>
<document>
<entity name="name"
query="SELECT * FROM name">
</entity>
</document>
</dataConfig>
如果我尝试创建一个新的集合，例如mysqlCol，我收到此错误
Error CREATEing SolrCore 'mysqlCol': Unable to create core: mysqlCol Caused by: org.apache.solr.handler.dataimport.DataImportHandler
OR
如果我尝试将这些代码行放在现有的collection1中并从带有java -jar start.jar的cmd运行，那么错误就是
2758 [coreLoadExecutor-5-thread-1] ERROR org.apache.solr.core.CoreContainer û U
nable to create core: collection1
在\ lib \中我已经为mysql mysql-connector-java-5.1.31-bin.jar添加了驱动程序，但仍然没有。我使用的是Windows 7.任何帮助都将受到高度赞赏。

答案 0 :(得分：4)
您错误地设置了库的路径： 检查solrconfig.xml 应该有：
<lib dir="../../../dist/" regex="solr-dataimporthandler-.*\.jar" />
.....
`
它应该指向这个库所在的目录 - 我必须将其更改为默认安装的一个目录，你的可能会有所不同，你可以在开始时看到它工作的绝对路径。
