运行时jar中的FileNotFoundException

标签: java jar filenotfoundexception

我正在使用JavaFX,现在想分享我的工件。但是,当我从jar文件运行时,我在其中一个xml上获得了运行时FNFE(其jasper报告打印布局文件)。该文件位于我的resources文件夹中,这就是我在代码中获取它的方式:

InputStream input = new FileInputStream(new File(getClass().getClassLoader().getResource("Debtors_A4.jrxml").getFile()));

我的堆栈跟踪显示:

我应该如何访问文件以便在运行时可用?该文件最初位于resources的子文件夹中,但我只是将其移出并尝试了这种方式,但无济于事。我怎样才能解决这个问题?当我从IDE运行此程序时,jrxml会毫无问题地打开。但是在运行时,它会触发异常。
