我正在尝试使用solr进行完全导入并收到以下错误:

<dataConfig>

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

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吗?
更新
下载solr时,我正在运行示例附带的码头。
我编写了db示例以使用sql server。
我已将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:
16:29:54错误DocBuilder处理时出现异常:成员文档:SolrInputDocument(fields:[]):org.apache.solr.handler.dataimport.DataImportHandlerException:无法执行查询:SELECT * FROM Members Processing Document#1

16:29:55错误DataImporter完全导入失败:java.lang.RuntimeException:java.lang.RuntimeException:org.apache.solr.handler.dataimport.DataImportHandlerException:无法执行查询:SELECT * FROM Members Processing Document# 1
我也收到有关唯一密钥的警告:
16:29:49 WARN IndexSchema架构中没有指定uniqueKey。
即使我已将id
设为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"/>
答案 0 :(得分:0)
不,正如它在错误日志中明确指出的那样,com.microsoft.sqlserver.jdbc.SQLServerDriver缺少JDBC驱动程序jar文件。这是由供应商提供的,在本例中是microsfot sqlserver。您需要使其可用于运行solr实例的容器。如果您使用tomcat将其复制到tomcat_home \ lib目录中。您将在sql server安装中找到jar文件或询问您的sql server admin。
