ResourceUtils.extractJarFileURL介绍

[英]Extract the URL for the actual jar file from the given URL (which may point to a resource in a jar file or to a jar file itself).
[中]从给定的URL（可能指向jar文件中的资源或jar文件本身）中提取实际jar文件的URL。

 * (which may point to a resource in a jar file or to a jar file itself).
 * <p>In the case of a jar file nested within a war file, this will return
 * a URL to the war file since that is the one resolvable in the file system.
 * @param jarUrl the original URL
 * @return the URL for the actual jar file
 * @throws MalformedURLException if no valid jar file URL could be extracted
 * @since 4.1.8
 * @see #extractJarFileURL(URL)
