访问打包到jar文件中的文件 [英] Accessing files packaged into a jar file

问题描述

我创建了一个带有可运行编译类和一些模板文件（文本）的jar文件。我现在想要使用打包到jar中的文本文件在应用程序中作为 File 对象进行分发。

I created a jar file with a runnable compiled class and some template files (text). I now want to use the text files packaged into the jar for distribution in the application as File objects.

I试图只使用不起作用的相对路径。 如何获取指向jar中文本文件的文件对象？

I tried to just use relative paths which did not work. How do I get a File object pointing to a text file which is in the jar?

有没有办法做到这一点，所以它在运行unpackaged类文件和从具有相同代码的jar时都可以工作，还是需要使用单独的函数？

Is there a way to do this so it will work both when running the unpackaged class files and from a jar with the same code, or will I need to use separate functions?

推荐答案

你可以像 Class.getResourceAsStream（String） 或类似内容。

from inside jar you can use it like Class.getResourceAsStream(String), or something similar.

从外面看它的文件不是它的jar所以你必须提取它以便实际使用内部文件

from out side its not the file its jar so you will have to extract it in order to actually use inside file
