Java網絡教程:JarURLConnection

Java的JarURLConnection類用來連接Java Jar文件。一旦連接上，你可以獲取Jar文件的信息。一個簡單的例子如下：

String urlString = "https://butterfly.jenkov.com/"
                 + "container/download/"
                 + "jenkov-butterfly-container-2.9.9-beta.jar";

URL jarUrl = new URL(urlString);
JarURLConnection connection = new JarURLConnection(jarUrl);

Manifest manifest = connection.getManifest();

JarFile jarFile = connection.getJarFile();
//do something with Jar file...
