SOLR配置麻烦(SOLR configuration troule)

我正在按照Youtube上的“在Windows Tutorial上运行Nutch和Solr”教程(第1部分)并尝试正确配置Solr。 我在C:\ Program Files \ Apache Software Foundation \ Tomcat 7.0 \ webapps \ solr \ WEB-INF \ web.xml文件中进行了更改,如教程中所述 - 将solr主路径放入:

<env-entry-value>C:\cygwin64\home\solr\example\solr</env-entry-value>

我在浏览器中获益:

    HTTP Status 500 - {msg=SolrCore 'collection1' is not available due to init failure: Error opening new searcher,
trace=org.apache.solr.common.SolrException: SolrCore 'collection1' is not available due to init 
failure: Error opening new searcher at 
org.apache.solr.core.CoreContainer.getCore(CoreContainer.java:745) at 
org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:307) at ...

当我将文件夹C:\ cygwin64 \ home \ solr \ example \ solr的内容复制到C:\ solr中的新文件夹并将solr路径更改为:

<env-entry-value>C:\solr</env-entry-value>

它工作正常。 当我设置Java系统属性solr.solr.home时,我的Solr Home:Windows> Start> Monitor Tomcat> Java Tab> Java Options - >输入以下条目:

-Dsolr.solr.home=c:\solr

它在这个cae中工作得很好,但是当我把它放入时:

-Dsolr.solr.homeC:\cygwin64\home\solr\example\solr

我希望solr能像在教程中那样在cygwin下工作,因为稍后可能需要在该文件夹中,而我无法在问题所在的地方找到它。 提前致谢。


I am following the tutorial "Running Nutch and Solr on Windows Tutorial" (Part 1) from Youtube and trying to configure properly Solr. I make the change in the C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\solr\WEB-INF\web.xml file as explained in the tutorial - putting the solr home path:

<env-entry-value>C:\cygwin64\home\solr\example\solr</env-entry-value>

And I gain in the browser:

    HTTP Status 500 - {msg=SolrCore 'collection1' is not available due to init failure: Error opening new searcher,
trace=org.apache.solr.common.SolrException: SolrCore 'collection1' is not available due to init 
failure: Error opening new searcher at 
org.apache.solr.core.CoreContainer.getCore(CoreContainer.java:745) at 
org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:307) at ...

When I copy the content of the folder C:\cygwin64\home\solr\example\solr to a new folder at C:\solr and the change the solr path to:

<env-entry-value>C:\solr</env-entry-value>

it works fine. It is the same situation when I Set the Java system property solr.solr.home my Solr Home:Windows > Start > Monitor Tomcat > Java Tab > Java Options -> Enter the following entry:

-Dsolr.solr.home=c:\solr

It works fine in this cae, but not when I put:

-Dsolr.solr.homeC:\cygwin64\home\solr\example\solr

I want solr to work under cygwin as in the tutorial, since it might be needed in that folder later, and I can't get it where could be the problem. Thanks in advance.

最满意答案

CFMutableDictionary的文档说:

CFDictionary Reference提供了管理字典的基本接口。

...这CFDictionaryGetValue()您引导至CFDictionaryGetValue()


The documentation for CFMutableDictionary says:

The basic interface for managing dictionaries is provided by CFDictionary Reference.

... which leads you to CFDictionaryGetValue().
