java.io.FileNotFoundException log4j

Question

我遇到了一个问题，目前我得到了以下错误。当然，这是因为用户无法访问C:这不是问题所在。问题是，我找不到任何提及：

• log4j
• org.apache.log4j
• org.apache.log4j.xml.DOMConfigurator

我查看了类路径，导入了组成程序的所有类、与项目相关的XML文件，并且找不到对项目的任何引用。

我需要知道如何跟踪它被引用的位置，这样我就可以将它从项目中删除。

错误示例

任何帮助/想法，

我曾经遇到过同样的问题:我使用的第三方库内部有一个log4j副本。

下面的代码将给出加载log4j的位置

DOMConfigurator.class.getProtectionDomain().getCodeSource().getLocation();

这样您就可以找到可能的配置文件的位置。
