Solr dataSource错误(Solr dataSource error)
我正在尝试使用solr进行完全导入并收到以下错误：
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 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 at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:270) at org.apache.solr.handler.dataimport.DataImporter.doFullImport(DataImporter.java:411) at org.apache.solr.handler.dataimport.DataImporter.runCmd(DataImporter.java:476) at org.apache.solr.handler.dataimport.DataImporter$1.run(DataImporter.java:457) Caused by: java.lang.RuntimeException: org.apache.solr.handler.dataimport.DataImportHandlerException: Could not load driver: com.microsoft.sqlserver.jdbc.SQLServerDriver Processing Document # 1 at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:410) at org.apache.solr.handler.dataimport.DocBuilder.doFullDump(DocBuilder.java:323) at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:231) ... 3 more Caused by: org.apache.solr.handler.dataimport.DataImportHandlerException: Could not load driver: com.microsoft.sqlserver.jdbc.SQLServerDriver Processing Document # 1 at org.apache.solr.handler.dataimport.DataImportHandlerException.wrapAndThrow(DataImportHandlerException.java:71) at org.apache.solr.handler.dataimport.JdbcDataSource.createConnectionFactory(JdbcDataSource.java:116) at org.apache.solr.handler.dataimport.JdbcDataSource.init(JdbcDataSource.java:64) at org.apache.solr.handler.dataimport.DataImporter.getDataSourceInstance(DataImporter.java:383) at org.apache.solr.handler.dataimport.ContextImpl.getDataSource(ContextImpl.java:99) at org.apache.solr.handler.dataimport.SqlEntityProcessor.init(SqlEntityProcessor.java:53) at org.apache.solr.handler.dataimport.EntityProcessorWrapper.init(EntityProcessorWrapper.java:74) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:427) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:408) ... 5 more Caused by: java.lang.ClassNotFoundException: Unable to load com.microsoft.sqlserver.jdbc.SQLServerDriver or org.apache.solr.handler.dataimport.com.microsoft.sqlserver.jdbc.SQLServerDriver at org.apache.solr.handler.dataimport.DocBuilder.loadClass(DocBuilder.java:916) at org.apache.solr.handler.dataimport.JdbcDataSource.createConnectionFactory(JdbcDataSource.java:114) ... 12 more Caused by: org.apache.solr.common.SolrException: Error loading class 'com.microsoft.sqlserver.jdbc.SQLServerDriver' at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:470) at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:401) at org.apache.solr.handler.dataimport.DocBuilder.loadClass(DocBuilder.java:906) ... 13 more Caused by: java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.net.FactoryURLClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:454)<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>可能是因为不可能使用集成安全性吗？
或者连接字符串有什么问题？
更新：
下载solr时，我正在运行示例附带的码头。
我编辑了db示例以使用sql server。
我将
sqljdbc.jar和sqljdbc4.jar复制到\solr-4.6.0\example\example-DIH\solr\db\lib和\solr-4.6.0\example\lib主目录设置为
\solr-4.6.0\example\example-DIH\solr现在这是一个新错误：

Or is there anything wrong with the connection string?
UPDATE:
I'm running the jetty that comes with the example when downloading solr.
I have edited the db example to use sql server.
I copied
sqljdbc.jarandsqljdbc4.jarto\solr-4.6.0\example\example-DIH\solr\db\liband\solr-4.6.0\example\libThe home directory is set to
\solr-4.6.0\example\example-DIH\solrNow it's a new error:

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
I also get a warning about unique key:
16:29:49 WARN IndexSchema no uniqueKey specified in schema.
Even though I have set
idtouniqueKey<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.

最满意答案
尽量避免使用select语句。 还学习使用
Application.ScreenUpdating属性来加速代码（这会禁用每次写入Excel工作表之间的屏幕刷新，并在最后更新所有内容，使其更快）Sub sumif_test() Dim ws As Worksheet Dim NoCol As Integer, NoRow As Integer Dim CritRng As Range, SumRng As Range Application.ScreenUpdating = False Set ws = Worksheets("AB") With ws NoRow = .Cells(.Cells.Rows.Count, 1).End(xlUp).Row NoCol = .Cells(1, .Cells.Columns.Count).End(xlToLeft).Column Set CritRng = .Range("A:A") Set SumRng = .Range("N:N") End With For r = 2 To NoRow Cells(r, NoCol) = WorksheetFunction.SumIf(CritRng, Cells(r, 1), SumRng) Next r Application.ScreenUpdating = True End Sub我重写了你的代码以避免使用select语句。 请看一下它，看看你是否可以弄清楚每个部分的作用。
Try to avoid using select statements. Also learn to use the
Application.ScreenUpdatingproperty to speed up your code (This disables the screen refreshing between each write to the excel sheet and updates everything at the end making it much faster)Sub sumif_test() Dim ws As Worksheet Dim NoCol As Integer, NoRow As Integer Dim CritRng As Range, SumRng As Range Application.ScreenUpdating = False Set ws = Worksheets("AB") With ws NoRow = .Cells(.Cells.Rows.Count, 1).End(xlUp).Row NoCol = .Cells(1, .Cells.Columns.Count).End(xlToLeft).Column Set CritRng = .Range("A:A") Set SumRng = .Range("N:N") End With For r = 2 To NoRow Cells(r, NoCol) = WorksheetFunction.SumIf(CritRng, Cells(r, 1), SumRng) Next r Application.ScreenUpdating = True End SubI've rewritten your code to avoid using the select statement. Please take a look at it and see if you can figure out what each part does.
