Java Swing：无法使用getResource加载图像 [英] Java Swing: unable to load image using getResource

问题描述

尝试将图像添加到类目录时，我试图找出问题所在。 （这样做当我导出为可运行的JAR时，图像包含在包中）。

I'm trying to isolate where the problem could be when trying to add an image to the class directory. (Doing this so when I export as a runnable JAR, the image is included in the package).

所以我得到了位于'C的strawberry.jpg文件：\ Users \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
谢谢！

So I've got the strawberry.jpg file sitting in 'C:\Users\sean\workspace\myApps\src\testing' Could you advise what I'm missing? Thanks!

package testing;

import java.awt.*;
import javax.swing.*;

public class IconTest {

    public static void main(String[] arguments) {

        JFrame frame1 = new JFrame();
        frame1.setTitle("Frame1");
        frame1.setSize(500, 500);
        frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        FlowLayout flo = new FlowLayout();
        frame1.setLayout(flo);

        JLabel label1 = new JLabel(new ImageIcon(
            IconTest.class.getResource("strawberry.jpg")));
        frame1.add(label1);
        frame1.setVisible(true);
    }
}

推荐答案

我如下例所示：

public static void main(String[] arguments) throws IOException {

    JFrame frame1 = new JFrame();
    frame1.setTitle("Frame1");
    frame1.setSize(500, 500);
    frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    FlowLayout flo = new FlowLayout();
    frame1.setLayout(flo);

    InputStream resourceAsStream = IconTest.class.getResourceAsStream("strawberry.jpg");
    Image image = ImageIO.read(resourceAsStream);

    JLabel label1 = new JLabel(new ImageIcon(image));
    frame1.add(label1);
    frame1.setVisible(true);
}
