"Cannot locate configuration source" when using commons-configuration XMLConfiguration with Tomcat
提问by Bruno Shine
I'm building two apps that uses commons-configuration XMLConfiguration. Since the apps are related, I've build another project, called commons, that has a custom configuration manager that initializes the XMLConfiguration like so:
我正在构建两个使用 commons-configuration XMLConfiguration 的应用程序。由于应用程序是相关的，我构建了另一个名为 commons 的项目，它有一个自定义配置管理器，可以像这样初始化 XMLConfiguration：
config = new XMLConfiguration("conf/config.xml");
What happens is that the "command-line" app works fine, loading the configuration file. But when I try to use my custom configuration manager on a webapp (using Tomcat) I get a
发生的情况是“命令行”应用程序工作正常，加载了配置文件。但是当我尝试在 web 应用程序（使用 Tomcat）上使用我的自定义配置管理器时，我得到一个
org.apache.commons.configuration.ConfigurationException: Cannot locate configuration source
org.apache.commons.configuration.ConfigurationException：找不到配置源
I've placed the conf directory on the WEB-INF folder, the root folder and the META-INF folder. I've also tried with "/conf/config.xml", "./conf/config.xml"and "../conf/config.xml".
我已将 conf 目录放在 WEB-INF 文件夹、根文件夹和 META-INF 文件夹中。我也试过"/conf/config.xml","./conf/config.xml"和"../conf/config.xml"。
The only time I got this to work - on the web app - was using an absolute path.
我唯一一次让它工作 - 在网络应用程序上 - 是使用绝对路径。
What am I missing?
我错过了什么？
Thanks, Bruno

Use ServletContext.getResourceAsStream(..), and pass the stream. Or if the file is on the classpath, you can use getClass().getResourceAsStream(..)
使用ServletContext.getResourceAsStream(..), 并传递流。或者，如果文件在类路径上，您可以使用getClass().getResourceAsStream(..)

Actually, org.apache.commons.configuration.XMLConfigurationdoes not have a constructor which accepts an InputStream, so getClass().getResourceAsStream()will not work. There is an XMLConfigurationconstructor which takes a URL, however, so use getClass().getResource()instead.
实际上，org.apache.commons.configuration.XMLConfiguration没有接受 an 的构造函数InputStream，因此getClass().getResourceAsStream()不会起作用。XMLConfiguration但是，有一个构造函数接受 URL，因此请getClass().getResource()改用。
