这是我的配置文件
dataconfig.xml

<dataConfig>
<dataSource type="JdbcDataSource" driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" url="jdbc:sqlserver://*.*.*.*;databaseName=*" user="*" password="*"/>
<document name="shop">
<entity name="*" query="select * from sg">
<field column="id" name="id"/>
<field column="sid" name="sid"/>
<field column="pid" name="pid"/>
</entity>
</document>
</dataConfig>

solrconfig.xml 如下

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">dataconfig.xml</str>
</lst>
</requestHandler>

到底是什么原因啊 求教
