如何将“jar：file”URI转换为Jar文件的路径？

Question

如何从jar:file:/C:/Program%20Files/test.jar!/foo/bar转到指向File的{​​{1}}？

Answer 1

以下代码适用于我（基于How do I get just the jar URL from a jar: URL containing a "!" and a specific file in the jar?）：

URL url = new URL("jar:file:/C:/Program%20Files/test.jar!/foo/bar");
JarURLConnection connection = (JarURLConnection) url.openConnection();
File file = new File(connection.getJarFileURL().toURI())
