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File指向C:/Program Files/test.jar？

Answer 1

下面的代码对我的作品（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()) 

Answer 2

你可以做this.This工作

ClassLoader loader = this.getClass().getClassLoader(); 
URL url = loader.getResource("resource name"); 
String[] filePath = null; 
String protocol = url.getProtocol(); 
if(protocol.equals("jar")){ 
    url = new URL(url.getPath()); 
    protocol = url.getProtocol(); 
} 
if(protocol.equals("file")){ 
    String[] pathArray = url.getPath().split("!"); 
    filePath = pathArray[0].split("/",2); 
} 

文件所需=新的文件（文件路径[1]）;
