如何仅从jar中获取jar URL：包含“！”的URL 还有罐子里的特定文件？

如果MS-Windows不会被前导斜杠冒犯，则可以这样做：

    final URL jarUrl =        new URL("jar:file:/C:/proj/parser/jar/parser.jar!/test.xml");    final JarURLConnection connection =        (JarURLConnection) jarUrl.openConnection();    final URL url = connection.getJarFileURL();    System.out.println(url.getFile());
