推荐答案

如何找到文件名？

How can I find its file name?

你已经拥有它。也许你想找到绝对的文件位置？您可以使用 ServletContext #getRealPath（） 。

You already have it. Maybe you meant to find the absolute file location? You can use ServletContext#getRealPath() for this.

String relativeWARPath = "/META-INF/MANIFEST.MF";
String absoluteDiskPath = getServletContext().getRealPath(relativeWARPath);
File file = new File(absoluteDiskPath);
// ...

或者如果你想得到 InputStream 直接使用 ServletContext #getResourceAsStream（） 。

Or if you want to get it as InputStream directly, use ServletContext#getResourceAsStream().

InputStream input = getServletContext().getResourceAsStream("/META-INF/MANIFEST.MF");
// ...
