Solr的數據源錯誤

Question

我試圖使一個完整的進口使用Solr和接收以下錯誤：

DataImporter Full Import failed:java.lang.RuntimeException: java.lang.RuntimeException: org.apache.solr.handler.dataimport.DataImportHandlerException: Could not load driver: com.microsoft.sqlserver.jdbc.SQLServerDriver Processing Document # 1

<dataConfig> 
    <dataSource 
    type="JdbcDataSource" 
    driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
    url="jdbc:sqlserver://localhost\ARBETSDATOR\SQLEXPRESS;integratedSecurity=true;databaseName=189021-resurs"/> 

    <document name="members"> 

    <entity name="member" query="SELECT * FROM Members"> 

     <field column="MemberId" name="id"/> 
     <field column="Name" name="name"/> 

    </entity> 
    </document> 

</dataConfig> 

難道說這是不可能的使用集成的安全性？

或者連接字符串有什麼問題嗎？

UPDATE：

我正在下載的Solr時自帶的例子碼頭。

我編輯了使用sql server的db示例。

我複製sqljdbc.jar和sqljdbc4.jar到\solr-4.6.0\example\example-DIH\solr\db\lib和\solr-4.6.0\example\lib

主目錄設置爲\solr-4.6.0\example\example-DIH\solr

現在是一個新的錯誤：

16:29:54 ERROR DocBuilder Exception while processing: member document : SolrInputDocument(fields: []):org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to execute query: SELECT * FROM Members Processing Document # 1

16:29:54 ERROR DataImporter Full Import failed:java.lang.RuntimeException: java.lang.RuntimeException: org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to execute query: SELECT * FROM Members Processing Document # 1

16:29:55 ERROR DocBuilder Exception while processing: member document : SolrInputDocument(fields: []):org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to execute query: SELECT * FROM Members Processing Document # 1

16:29:55 ERROR DataImporter Full Import failed:java.lang.RuntimeException: java.lang.RuntimeException: org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to execute query: SELECT * FROM Members Processing Document # 1

我也得到了有關唯一密鑰警告：

16:29:49 WARN IndexSchema no uniqueKey specified in schema.

即使我已經設置id到uniqueKey

<fields> 
<field name="id" type="string" indexed="true" stored="true" required="true" /> 
<field name="name" type="text" indexed="true" stored="true"/> 

<field name="text" type="text" indexed="true" stored="false" multiValued="true"/> 
</fields> 


<!-- Field to use to determine and enforce document uniqueness. 
    Unless this field is marked with required="false", it will be a required field 
    --> 
<uniqueKey>id</uniqueKey> 

<!-- field for the QueryParser to use when an explicit fieldname is absent --> 
<defaultSearchField>text</defaultSearchField> 


<copyField source="id" dest="text"/> 
<copyField source="name" dest="text"/> 

Answer 1

沒有，因爲它清楚地在錯誤日誌中說，您的JDBC驅動程序jar文件缺少com.microsoft.sqlserver.jdbc.SQLServerDriver.That被設供應商，在這種情況下是microsfot sqlserver。您需要將它提供給運行solr實例的容器。如果你使用的是tomcat，將它複製到tomcat_home \ lib目錄下。你會在你的sql server安裝中找到jar文件，或者詢問你的sql服務器管理員。
