Solr 4.2中的数据导入不起作用？(Data Import in Solr 4.2 not working?)
我的data-config.xml如下所示，我和solrconfig.xml一起保存在Conf文件夹中： -
<dataConfig> <dataSource name="Sample" driver="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/Sample" user="postgres" password="P@ssword"> <document name="oneDocs"> <entity dataSource="Sample" name="entity1" query="select FirstName from Employee"> <field column="EmpId" name="EmpId" /> <field column="FirstName" name="FirstName" /> <field column="LastName" name="LastName" /> </entity> </document> </dataSource> </dataConfig>我的solrconfig.xml如下： -
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">data-config.xml</str> </lst> </requestHandler>我还试图通过以下方式添加库： -
<lib dir="../../../contrib/extraction/lib" regex=".*\.jar" /> <lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" /> <lib dir="../../../contrib/clustering/lib/" regex=".*\.jar" /> <lib dir="../../../dist/" regex="solr-clustering-\d.*\.jar" /> <lib dir="../../../contrib/dataimporthandler/lib/" regex=".*\.jar" /> <lib dir="../../dist/" regex="solr-dataimporthandler-\d.*\.jar" /> <lib dir="../../dist/" regex="postgresql-9.2-1002.jdbc3-\d.*\.jar" /> <lib dir="../../../contrib/langid/lib/" regex=".*\.jar" /> <lib dir="../../../dist/" regex="solr-langid-\d.*\.jar" /> <lib dir="../../../contrib/velocity/lib" regex=".*\.jar" /> <lib dir="../../../dist/" regex="solr-velocity-\d.*\.jar" /> <!-- If a 'dir' option (with or without a regex) is used and nothing is found that matches, it will be ignored --> <lib dir="/total/crap/dir/ignored" />我不断得到同样的错误： -

注意：我使用的是Postgres和Apache Tomcat 7以及Java 7。
My data-config.xml is as follows and I have kept in the the Conf folder along with the solrconfig.xml :-

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">data-config.xml</str> </lst> </requestHandler>I have also tried to add the libraries in the following ways :-

您的data-config.xml存在缺陷。 您已将文档元素包装到数据源元素中。 两者都需要与dataConfig元素的直接子级处于同一级别。
这就是您发布的例外情况的原因：
Data Config问题：DataImportHandler配置文件必须有一个节点。
XML解析器未将document元素作为dataConfig的子节点。
试试这样：
<dataConfig> <dataSource name="Sample" driver="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/Sample" user="postgres" password="P@ssword" /> <document name="oneDocs"> <entity dataSource="Sample" name="entity1" query="select FirstName from Employee"> <field column="EmpId" name="EmpId" /> <field column="FirstName" name="FirstName" /> <field column="LastName" name="LastName" /> </entity> </document> </dataConfig>Your data-config.xml is flawed. You have wrapped the document elment into the datasource element. Both need to be on the same level as direct child of the dataConfig element.
This is why the exception you posted states:
Data Config problem: DataImportHandler configuration file must have one node.
The XML parser does not find the document element as child node of dataConfig.
Try it like this:
<dataConfig> <dataSource name="Sample" driver="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/Sample" user="postgres" password="P@ssword" /> <document name="oneDocs"> <entity dataSource="Sample" name="entity1" query="select FirstName from Employee"> <field column="EmpId" name="EmpId" /> <field column="FirstName" name="FirstName" /> <field column="LastName" name="LastName" /> </entity> </document> </dataConfig>更多推荐
