Java 中的配置异常？
决定使用 Apache 的通用配置包来解析 XML 文件。
我决定做一个：
XMLConfiguration xmlConfig = new XMLConfiguration(file);
Eclipse 抱怨我没有捕获异常（未处理的异常类型 ConfigurationException），所以我用 try/catch 命中了可靠的包围并且它添加了以下代码：
try
{
XMLConfiguration xmlConfig = new XMLConfiguration(file);
}
catch (ConfigurationException ex)
{
ex.printStackTrace();
}
但是现在它抱怨：
No exception of type ConfigurationException can be thrown; an exception type
must be a subclass of Throwable
我不明白为什么当 Eclipse 建议添加它时它给了我这个错误。
Decided to use Apache's Common Configuration package to parse an XML File.
I decided to do a:
XMLConfiguration xmlConfig = new XMLConfiguration(file);
To which Eclipse complained that I haven't caught an exception(Unhandled exception type ConfigurationException), so I hit the trusty surround with try/catch and it added the following code:
try
{
XMLConfiguration xmlConfig = new XMLConfiguration(file);
}
catch (ConfigurationException ex)
{
ex.printStackTrace();
}
However now it's complaining:
No exception of type ConfigurationException can be thrown; an exception type
must be a subclass of Throwable
I don't understand why it's gave me that error when Eclipse is the one that suggested to add it.

org.apache.commons.configuration.ConfigurationException 扩展了 org.apache.commons.lang.exception.NestableException。
您的道路上也有 Commons Lang 吗？如果不是，Eclipse 将无法解析
ConfigurationException类，并且您将收到该错误。org.apache.commons.configuration.ConfigurationExceptionextendsorg.apache.commons.lang.exception.NestableException.Do you have Commons Lang on your path also? If not, Eclipse will fail to resolve the
ConfigurationExceptionclass, and you'll get that error.您需要 Apache Commons Lang 2.6
（当前版本的 Apache Common Configuration (1.8) 不会适用于 Apache Common Lang 库的 3.1 版本，您可能需要在此处检查通用配置依赖项）
You need Apache Commons Lang 2.6
(Current release of Apache Common Configuration (1.8) wont works with version 3.1 of Apache Common Lang library, you might need to check Common configuration dependencies here )
我也面临这个问题。
要解决此问题 - 请从 http://commons.apache.org/ 下载 commons-lang-2.6.jar正确/commons-lang/download_lang.cgi
并将此 commons-lang-2.6.jar 添加到项目的构建路径中。这应该可以解决你的问题。
I also faced this problem.
To fix this - Please download commons-lang-2.6.jar from http://commons.apache.org/proper/commons-lang/download_lang.cgi
and add this commons-lang-2.6.jar to your project's build path. this should solve your problem.
