【问题描述】：
我写了以下代码：
public static void main(String[] args){
ApplicationContext ctx= new ClassPathXmlApplicationContext("classpath:/org/postprocessor/conf/dataSupport.xml");
DaoImpl daoImpl=null;
FileZipper fileZipper=null;
}
但是当我执行这个时，我得到了以下异常：
log4j:WARN Please initialize the log4j system properly.

为什么我得到这个异常，即使文件在那里？
【问题讨论】：
-
FileNotFoundException: class path resource [org/postprocessor/config/dataSupport.xml] cannot be opened because it does not exist很清楚 imo。 -
但是文件在那里，我可以看到包和文件...有什么遗漏的
-
我确定出了什么问题：它找不到您的文件。你确定你的 xml 文件在你的类路径中吗？ （查看您的输出文件夹，如果它是 web 应用程序，可能在 WEB-INF/classes 中。
-
它不是一个webapp，但是这个文件在这个包src org/postprocessor/dataSupport.xml下
-
但是这个包在 Eclipse 中显示为白色，而所有其他包为棕色..这是否意味着这不存在...对不起，我是 maven 项目的新手
