在Eclipse中导出一个JAR文件并引用一个文件 [英] Exporting an JAR file in Eclipse and referencing a file

问题描述

  URL logoPath = new MainApplication（ ）.getClass（）getClassLoader（）的getResource（ IMG / logo.jpg）。。 
  

使用该方法获取文件的URL并将其转换为字符串。然后，我必须将该字符串除以5，以摆脱此输出file：/ C：/Users/Stephen/git/ILLA/PoC/bin/img/logo.jpg

然而，当我将它导出为jar并运行它遇到麻烦。该URL现在显示为/ILLA.jar !/，我的图片只是空白。我有一个直觉，这是绊倒了我怎么解决这个问题？

干杯

解决方案

参见这里：从资源路径创建文件对象到jar文件中的图像

  String imgName =/resources/images/image.jpg; 
 InputStream in = getClass（）。getResourceAsStream（imgName）; 
 ImageIcon img = new ImageIcon（ImageIO.read（in））; 
  

请注意，您需要在档案中使用资源流。

I have a project with a image stored as a logo that I wish to use.

URL logoPath = new MainApplication().getClass().getClassLoader().getResource("img/logo.jpg");

Using that method I get the URL for the file and convert it to string. I then have to substring that by 5 to get rid of this output "file:/C:/Users/Stephen/git/ILLA/PoC/bin/img/logo.jpg"

However when I export this as a jar and run it I run into trouble. The URL now reads /ILLA.jar!/ and my image is just blank. I have a gut feeling that it's tripping me up so how do I fix this?

Cheers

解决方案

See here: Create a file object from a resource path to an image in a jar file

String imgName = "/resources/images/image.jpg";
InputStream in = getClass().getResourceAsStream(imgName);
ImageIcon img = new ImageIcon(ImageIO.read(in));

Note it looks like you need to use a stream for a resource inside an archive.
