试图从jar文件加载图标 [英] Trying to load icon from jar file

问题描述

我正在尝试从jar文件加载图标。我都试图从jar文件中的类以及jar文件之外的类加载它。

I am trying to load icons from a jar file. I have both tried to load it from classes within the jar file as well as classes outside the jar file.

在jarfile之外 - 返回空异常

outside of the jarfile - returned a null exception

java.net.URL imageURL = LoadHTMLExample.class.getClassLoader()
    .getResource("icons/mouse.png");

位于LoadHTMLExample的jar文件一侧

in side of the jar file in the LoadHTMLExample

java.net.URL imageURL = this.getClass().getClassLoader()
    .getResource("icons/mouse.png");

得到同样的错误。

I还尝试了
icons，/ iconsicons // icons / _mouse.pngicons / mouse.png

I have also tried variations of "icons", "/icons" "icons/" "/icons/mouse.png" "icons/mouse.png"

似乎没有任何想法

图标在jar文件中

jar
 --icons --- {all the images}

 --com.blah.blah

推荐答案

跳过类加载器，将资源作为流来获取。如果您不需要URL，可以将它们直接转换为BufferedImages。我已将流和异常处理作为进一步的练习。

Skip the class loader, and get the resource as a stream instead. If you don't need the URL you can turn them directly into BufferedImages like so. I've left the stream and exception handling as a further exercise.

InputStream stream = LoadHTMLExample.class
    .getResourceAsStream( "/icons/mouse.png" );
BufferedImage image = ImageIO.read( stream );

提问者需要将我们带回给所有人的网址别的建议。绝对是罐子里的图像不是吗？

Questioner needs the URL which brings us back to everyone else's suggestions. The images are definitely in the jar aren't they?
