I've been trying to figure this out for a couple of days, but I got to the point I lost my patience. The following are some code and my project structure.
几天来我一直试图弄清楚这一点，但我已经失去了耐心。以下是一些代码和我的项目结构。
QUESTION:how can I get getResources()to work in eclipse and after being imported to jar?
问题：我怎样才能getResources()在 eclipse 和导入到 jar 之后开始工作？
Thanks for the help.
谢谢您的帮助。
public enum Icons {
XXX("src/resoruces/icons/xyz.png");
private ImageIcon icon;
Icons(String path) {
try {
// will fail miserably in eclipse and after exporting to jar
URL imageURL = getClass().getClassLoader().getResource(path);
icon = new ImageIcon(imageURL);
} catch (Exception e) {
// works like a char in eclipse and after creating the jar file
// with the files in the same directory
System.out.println("getResoruce() did not work");
icon = new ImageIcon(path);
}
}

If the png files have been packaged into the JAR in the same locations as they are in the original src directory then
如果 png 文件已打包到 JAR 中的位置与它们在原始 src 目录中的位置相同，则
XXX("resources/icons/xyz.png");
should produce the right result.
应该产生正确的结果。

Normally when exporting a JAR file from Eclipse, the contents of src/resourcesare exported minusthe srcpath name itself. To get the image to load from your JAR you could do:
通常情况下，从Eclipse中导出一个JAR文件时，内容src/resources出口减去的src路径名称本身。要从 JAR 加载图像，您可以执行以下操作：
InputStream stream = getClass().getResourceAsStream("/resources/icons/xyz.png");
ImageIcon icon= new ImageIcon(ImageIO.read(stream));
One way to know for sure is to check:
确定知道的一种方法是检查：
jar tvf yourjar.jar

srcdirectory is not available in classpath
src目录在类路径中不可用
InputStream imageInputStream = getClass().getClassLoader().getResourceAsStream("resources/icons/xyz.png");
byte[] imageData = org.apache.commons.io.IOUtils.toByteArray(in)
ImageIcon imageIcon = new ImageIcon(imageData, "description about image");
