java.io.FileNotFoundException：类路径资源应用程序上下文

Question

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;
}

但是当我执行此操作时，我得到以下异常：

log4j:WARN Please initialize the log4j system properly.

为什么即使文件存在，我也会收到此异常？
