访问.JAR文件中的图像 [英] Accessing images in a .JAR file

问题描述

我的程序中有一组5张图像。该程序将编译为单个 .JAR 文件，因此需要从中读取它们。但是，当我拨打电话时

I have a set of 5 images in my program. The program will be compiled as a single .JAR file, so they need to be read from it as such. However, when I make a call like

images = new ArrayPP<ImageIcon>(
          new ImageIcon(getClass().getResource("/bha/resources/Portal Test Chamber 17 - Part 1.png")),
          new ImageIcon(getClass().getResource("/bha/resources/Portal Test Chamber 17 - Part 2.png")),
          new ImageIcon(getClass().getResource("/bha/resources/Portal Test Chamber 17 - Part 3.png")),
          new ImageIcon(getClass().getResource("/bha/resources/revit logo - glass.png")),
          new ImageIcon(getClass().getResource("/bha/resources/The All-Knowing Octopus.png")));

适用于 JMenuItem s中的图标（例如， jMenuItem.setIcon（new javax.swing.ImageIcon（getClass（）。getResource（/ bha / resources / icon.png）））; 将始终在IDE中进行测试时，在编译为 JAR 文件时返回 null 。

which works for the icons in JMenuItems (for example, jMenuItem.setIcon(new javax.swing.ImageIcon(getClass().getResource("/bha/resources/icon.png"))); will always work) and when testing in an IDE, but returns as null when compiled as a JAR file.

推荐答案

鉴于getResource返回一个URL，我猜它不喜欢这些空格。作为测试，我尝试做

Given that getResource returns a URL, i'm guessing that it's not liking the spaces. As a test, i'd try doing

new ImageIcon(getClass().getResource(URLEncoder.encode("/bha/resources/Portal Test Chamber 17 - Part 1.png", "UTF-8"))),
