Java Apache Commons配置--无法加载/使用配置文件

我一直在尝试配置Java应用程序（特别是我的集成测试），但完全没有成功。我最初有一个XMLConfiguration，可以毫无问题地加载和使用它。我的目录设置如下所示：

• src
  • 试验
    • 爪哇
      • 我的包裹
    • 资源

以前，我在resources目录中有一个文件myconfig.xml。我是这样加载的：

private static XMLConfiguration configuration = null;
public static void configure() {
    try {
        configuration = new XMLConfiguration("myconfig.xml");
    }
    catch (ConfigurationException e) {
        System.err.println(e);
    }
}

现在，我正在尝试使用户可以通过在/etc或/home或其他文件中编写配置文件来配置应用程序，因此我在同一位置创建了一个名为config-test.xml的新文件：

<?xml version="1.0" encoding="ISO-8859-1"?>
<configuration>
    <!-- Attempt to load configuration provided on the system -->
    <xml fileName="/etc/myconf/myconfig.xml" config-optional="true" />

    <!-- Load default configuration from the classpath -->
    <xml fileName="myconfig.xml" />
</configuration>

当我运行集成测试时，我没有看到Yay，没有看到Herp，也没有看到Derp。如果我在尝试加载东西之前放置了一个

println

，它确实会打印，因此调用了

configure

。我从commons配置中获得的输出总计为：

等等等等等等。。。但我现在确实看到了“耶”。现在我不明白的是，它似乎不是在寻找我的非可选配置源，或者假设它位于我从未告诉过它的位置

编辑#2:

我仔细查看了一下我的输出结果，在commons的抱怨声中我发现它似乎最终加载了正确的文件。我想我能让它工作吗？当我像这样加载时，属性的路径可能会改变。。。我有些东西要试试。不管怎样，我问的问题已经解决了。谢谢你的帮助。

你的课程路径上似乎缺少了commons beanutils。确保罐子在那里。

Pfft。讨论如何加载配置文件。但他们是否忘记在绝对Windows路径（如c:\Users\USER\FOO\bar.xml）中检测文件URL？Commons 1.9将显示这一谨慎的信息

DEBUG DefaultFileSystem - Could not locate file C:\Users\USER\FOO\bar.xml at null: unknown protocol: c

奇怪。我已经习惯了maven为我处理依赖项，但它不在那里——我专门为它添加了一个依赖项，它确实改变了一些东西。谢谢我的类路径中有这个bean utils，问题仍然存在@Bozho
