Jar将图像作为资源 [英] Jar get image as resource

问题描述

我正试图从我的罐子里加载一张图片。但无论我为getResource（）提供什么字符串，它总是返回null。

I'm trying to get load an image from my jar. But no matter what string I supply for getResource() it always returns null.

try {
    System.out.println(Bootstrapper.class.getResource("./img/logo.png").toURI().getPath());
} catch (URISyntaxException ex) {
    Logger.getLogger(CrawlerFrame.class.getName()).log(Level.SEVERE, null, ex);


   }
   ImageIcon ii = new ImageIcon(Bootstrapper.class.getResource("./img/logo.png"));
   setIconImage(ii.getImage());

线程AWT-EventQueue-0java.lang中的异常。 NullPointerException
at net.sharpcode.crawler.ui.CrawlerFrame.init（CrawlerFrame.java:35）
at net.sharpcode.crawler.ui.CrawlerFrame。（CrawlerFrame.java:28）
at net.sharpcode.crawler.Bootstrapper $ 1.run（Bootstrapper.java:55）

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at net.sharpcode.crawler.ui.CrawlerFrame.init(CrawlerFrame.java:35) at net.sharpcode.crawler.ui.CrawlerFrame.(CrawlerFrame.java:28) at net.sharpcode.crawler.Bootstrapper$1.run(Bootstrapper.java:55)

我试过：

getResource("") 
getResource(".") 
getResource("./") 
getResource("/img/logo.png") 
Bootstrapper.class.getProtectionDomain().getCodeSource().getLocation().getPath()

推荐答案

this.getClass().getResource("/net/sharpcode/crawler/img/logo.png")
