我一直在尝试配置 Java 应用程序（特别是我的集成测试），但绝对没有成功。我最初有一个 XMLConfiguration，我可以毫无问题地加载和使用它。我的目录设置如下所示：
- 源代码
- 测试
- 爪哇
- 我的包裹
- 资源
- 爪哇
- 测试
之前，我在资源目录中有一个文件 myconfig.xml。我像这样加载它：
private static XMLConfiguration configuration = null;
public static void configure() {
try {
configuration = new XMLConfiguration("myconfig.xml");
}
catch (ConfigurationException e) {
System.err.println(e);
}
}
现在我正在尝试让用户可以通过在 /etc 或 /home 或其他任何内容中编写配置文件来自己配置应用程序，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>
文件 /etc/myconf/myconfig.xml 不存在，但这就是使它成为可选的全部意义。我尝试了几种不同的方法来加载我的配置，包括文档是如何做到的：http ://commons.apache.org/configuration/userguide/howto_configurationbuilder.html 。我目前拥有的是以下内容：
private static CombinedConfiguration configuration = null;
public static void configure() {
try {
DefaultConfigurationBuilder builder =
new DefaultConfigurationBuilder("config-test.xml");
configuration = builder.getConfiguration(true);
System.err.println("Yay");
}
catch (ConfigurationException e) {
System.err.println("Herp");
}
catch (Exception e) {
System.err.println("Derp");
}
}
当我运行集成测试时，我看不到 Yay，我看不到 Herp，我看不到 Derp。如果我println在尝试加载内容之前放置 a ，它会打印，所以configure被调用。我从公共配置中获得的输出为：

这些初始化方法只是调用configure然后尝试从加载的配置中获取数据。我已经用这个工作了几个小时了，真的可以用另一双眼睛。有任何想法吗？有什么我可以改变但我没有提到会影响这一点的吗？谢谢。

等等等等……但我现在确实看到了“耶”。现在我没有得到的是，它似乎没有在寻找我的非可选配置源，或者假设它位于我从未告诉它查找的位置。
编辑#2： 我仔细查看了我的输出，并埋头于来自公共的抱怨中，我发现它似乎最终加载了正确的文件。我想我可能有它的工作？当我像这样加载它时，也许我的属性路径会改变......我有一些东西要尝试。不管怎样，我问的问题已经解决了。谢谢您的帮助。
