Question

我试图搜索我的具体问题，但没有找到解决方案。我还在DIH上阅读了wiki，似乎一切设置正确，但我的查询仍然失败。谢谢你的帮助

我正在使用Tomcat 6.0运行Solr 3.1 Windows server 2003 r2和SQL 2008

我的sqljdbc4.jar位于C：\ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ lib

我的solrconfig.xml

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

我的db-data-config.xml

<dataConfig>
<dataSource driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"      url="://localhost:1433;DatabaseName=KnowledgeBase_DM" user="user" password="password" /> 
<document>
<entity name="Titles" query="SELECT mrID, mrTitle from KnowledgeBase_DM.dbo.AskMe_Data">
<field column="mrID" name="id" />  
<field column="mrTitle" name="title" />  
<entity name="Desc" query="select meDescription from KnowledgeBase_DM.dbo.AskMe_Data">
<field column="meDescription" name="description" />  
</entity>
</entity>
</document>
</dataConfig>

Answer 1

您似乎忘了描述要用于连接数据库的协议。对于MSSQL，它是

url="jdbc:sqlserver://localhost:1433;DatabaseName=KnowledgeBase_DM"

我很确定您不需要在查询中重新显示tue数据库名称，因为您已在您的URL中选择了它。 Wich将查询发送到：

 query="SELECT mrID, mrTitle from dbo.AskMe_Data"

我从来没有使用MSSQL，所以我不知道你是否应该使用dbo.AskMe_Data或只是，就像我总是使用它一样，AskMe_Data

我认为此代码应该可以解决问题：

<dataConfig>
    <dataSource  type="JdbcDataSource" driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
        url="jdbc:sqlserver://localhost:1433;DatabaseName=KnowledgeBase_DM" user="user" password="password" /> 
    <document>
        <entity name="Titles" query="SELECT mrID, mrTitle from dbo.AskMe_Data">
            <field column="mrID" name="id" />  
            <field column="mrTitle" name="title" />  
            <entity name="Desc" query="select meDescription from dbo.AskMe_Data">
                <field column="meDescription" name="description" />  
            </entity>
        </entity>
    </document>
</dataConfig>

Answer 2

sqljdbc4.jar应放在另一个目录

中

如果这是您配置文件的地方

C:\Program Files\Apache Software Foundation\Tomcat 6.0\solr\conf\solrconfig.xml

然后sqljdbc4.jar应该放在这里：

C:\Program Files\Apache Software Foundation\Tomcat 6.0\solr\lib\sqljdbc4.jar
