找不到Solr DataImportHandler [英] Solr DataImportHandler not found

问题描述

我使用的是Tomcat 6.0.26的 Solr 3.3.0 。我能够成功安装Solr，我甚至能够使用http：/ localhost：8084 / solr / admin访问它的web界面。

I am using Solr 3.3.0 with Tomcat 6.0.26. I was able to successfully install Solr and i was even able to access its web interface using http:/localhost:8084/solr/admin.

现在我想使用它的我已经在我的solrconfig中添加了以下内容：

Now i want to use its dataimporthandler to index data from my database.I have added following to my solrconfig:

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

我也在同一个目录中创建了一个data-config.xml。

I have also created a data-config.xml in same directory.

我的solrconfig文件有dataimport的以下位置

My solrconfig file has following location for dataimport

  <lib dir="../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" /> 

并且我已经检查dataimporthandler.jar文件存在于dist文件夹中的以下路径C：\ web \solr\example\lib\apache-solr-3.3.0 \ dist

And i have checked that dataimporthandler.jar file exist in the dist folder at following path C:\web\solr\example\lib\apache-solr-3.3.0\dist

但是每当我键入http：/ localhost：8084 / solr / dataimport或http：/ localhost：8084 / solr / admin / dataimport它说资源不可用。我认为这是一些问题与Tomcat设置，所以我停止tomcat，并尝试从cmd使用java -jar start.jar启动Solr。我收到以下错误

But whenever I type http:/localhost:8084/solr/dataimport or http:/localhost:8084/solr/admin/dataimport it says resource unavailable. I thought it was dur to some problem with Tomcat setting so i stopped tomcat and tried to start Solr from cmd using java -jar start.jar. And i get the following error

HTTP ERROR 500
Problem accessing /solr/. Reason:
Severe errors in solr configuration.
Check your log files for more detailed information on what may be wrong.
If you want solr to continue after configuration errors, change: 

<abortOnConfigurationError>false</abortOnConfigurationError>

in solr.xml

推荐答案

我一直在使用solr 4.1和tomcat查看这个问题。我不能包括我需要的库与< lib dir =../../ dist /regex =solr-dataimporthandler - 。* \.jar/> - > ，我认为这是正确的，因为从我有solrconfig.xml的目录，它是两个目录，一个到dist。直到我暂时在直接路径（对我来说，/ opt / solr / dist），我意识到，问题是我从错误的目录开始。原来，我需要的是：

I've been looking at this problem for a bit on my own, using solr 4.1 and tomcat. I wasn't able to include the library I needed with <lib dir="../../dist/" regex="solr-dataimporthandler-.*\.jar" /> -->, which I figured had to be correct because from the directory that I had the solrconfig.xml in, it was two directories up and one down to dist. It wasn't until I temporarily subbed in the direct path (for me, /opt/solr/dist) that I realized that the problem was that I was starting from the wrong directory. It turns out that what I needed was:

<lib dir="../dist/" regex="solr-dataimporthandler-.*\.jar" /> -->

因此，如果您在包含此文件时遇到问题，请检查您是否从目录包含您的conf目录，而不是conf目录本身。

So, if you're having trouble with including this, check that you're starting from the directory that contains your conf directory, and not the conf directory itself.
