我一直在尝试配置一个Java应用程序，特别是我的集成测试，但没有取得任何成功。最初，我有一个单独的XMLConfiguration可以无问题地加载和使用。我的目录设置如下：
src --test ----java ------mypackage ----resources
以前，我在资源目录中有一个myconfig.xml文件。我是这样加载它的：
当我运行集成测试时，我看不到Yay，也看不到Herp和Derp。如果在尝试加载内容之前放置
那些初始化方法只是调用了
src --test ----java ------mypackage ----resources
以前，我在资源目录中有一个myconfig.xml文件。我是这样加载它的：
private static XMLConfiguration configuration = null;
public static void configure() {
try {
configuration = new XMLConfiguration("myconfig.xml");
}
catch (ConfigurationException e) {
System.err.println(e);
}
}
现在我正在尝试让用户通过编写配置文件（位于/etc或/home等位置）来自行配置应用程序，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>
/etc/myconf/myconfig.xml文件不存在，但这正是使它可选的全部意义所在。我尝试了几种不同的方法来加载我的配置，包括文档中的方法：http://commons.apache.org/configuration/userguide/howto_configurationbuilder.html。目前我使用的是以下方式：
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，也看不到Herp和Derp。如果在尝试加载内容之前放置
println，它确实会打印，所以configure被调用了。我从commons配置中得到的输出如下：-------------------------------------------------------

那些初始化方法只是调用了
configure，然后尝试从加载的配置中获取数据。我已经花费了几个小时在这个问题上，现在真的需要另一双眼睛来帮忙。有什么想法吗？是否有任何我没有提到但会影响此问题的更改？谢谢。
编辑＃1（下午1:58）： 确保beanutils在类路径上后，我现在得到了一个从堆栈跟踪开始的brutal explosion。Running TestSuite

等等等等...但是我现在看到了“耶”。现在我不理解的是，它似乎没有查找我的非可选配置源，或者假设它在我从未告诉它查找的位置。
编辑#2： 我仔细查看了输出，并在commons的投诉中发现它最终似乎加载了正确的文件。我想我可能已经解决了这个问题？也许当我像这样加载它时，我的属性路径会改变...我有一些要尝试的东西。无论如何，我所问的问题已经得到解决。感谢您的帮助。
