如何在Java中从jar读取文件？ [英] How to read a file from jar in Java?

问题描述

我想读取位于我的课程路径中的 jar 之一内的XML文件。如何读取任何包含在 jar 中的文件

解决方案

如果你想从你的应用程序中读取这个文件，请使用：
$ b $ pre $ InputStream input = getClass（）。getResourceAsStream（/ classpath /到/我/文件）;

路径以/开头，但不是文件系统中的路径，在你的类路径中。所以，如果你的文件在类路径org.xml中被称为myxml.xml，那么你的路径就像/org/xml/myxml.xml。

InputStream读取文件的内容。如果你愿意的话，你可以把它包装到Reader中。

我希望有帮助。

I want to read an XML file that is located inside one of the jars included in my class path. How can I read any file which is included in the jar?

解决方案

If you want to read that file from inside your application use:

InputStream input = getClass().getResourceAsStream("/classpath/to/my/file");

The path starts with "/", but that is not the path in your file-system, but in your classpath. So if your file is at the classpath "org.xml" and is called myxml.xml your path looks like "/org/xml/myxml.xml".

The InputStream reads the content of your file. You can wrap it into an Reader, if you want.

I hope that helps.
