Java中的ConfigurationException？ [英] ConfigurationException in Java?

问题描述

决定使用Apache的Common Configuration包来解析XML文件。

我决定做一个：

  XMLConfiguration xmlConfig = new XMLConfiguration（file）; 
  

Eclipse抱怨我没有捕到异常（未处理的异常输入ConfigurationException ），所以我用try / catch 命中了可靠的环绕声，并添加了以下代码：

 尝试
 {
 XMLConfiguration xmlConfig = new XMLConfiguration（file）; 
} 
 catch（ConfigurationException ex）
 {
 ex.printStackTrace（）; 
} 
  

然而现在它正在抱怨：

 不能抛出ConfigurationException类型的异常;异常类型
必须是Throwable的子类
  

我不明白为什么给它Eclipse是建议添加它的那个错误。

解决方案

org.apache.commons .configuration.ConfigurationException extends org.apache.commons.lang.exception.NestableException 。

<你在路上也有Commons Lang吗？如果没有，Eclipse将无法解析 ConfigurationException 类，您将收到该错误。

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.

解决方案

org.apache.commons.configuration.ConfigurationException extends org.apache.commons.lang.exception.NestableException.

Do you have Commons Lang on your path also? If not, Eclipse will fail to resolve the ConfigurationException class, and you'll get that error.
