包含带有可执行jar的图像 [英] Including Images with an executable jar

问题描述

我一直在浏览Stackoverflow，寻找如何做到这一点，但我还没有成功

I have been browsing Stackoverflow all day looking for how to do this and I have not been successful yet

我打包了一个快速游戏，我做了一个可执行的jar但我没有正确引用图像我只引用了文件

I am packaging a quick game I made into a executable jar but I didnt reference the images correctly I just referenced the files

background = ImageIO.read(new File("wood.jpeg"));

我的课程在src默认包
我不确定我应该在哪里添加图片或者如果我必须将它添加到构建路径
或在最新版本的eclipse中将图像添加到构建路径的正确方法

I have my classes in src default package Im not sure where I should add the images or if I have to add it to the build path or correct way of adding the images to the build path in the newest version of eclipse

推荐答案

Jar中的文件不是磁盘上文件意义上的文件。它们只是一个（可能）压缩的字节流。

Files in a Jar are not files in the sense of a file on disk. They are simply a (possibly) compressed stream of bytes.

Java可以通过使用 ClassLoader

Java makes it easy to extract these "resources" from Jar files through the use of the ClassLoader

background = ImageIO.read(getClass().getResource("/wood.jpeg"));

应该有效......

Should work...

这个将返回 URL ， ImageIO 可用于加载资源。

This will return a URL which ImageIO can use to load the resource.

• Jar将图像作为资源


• 在Jar中加载资源

我可以列出更多内容。所以，是的，它被问了很多;）

And I could list some more. So, yeah, it gets asked a lot ;)
