Question

我正在尝试向我的程序添加背景音乐但是当我指定音频文件的路径时，我收到错误消息。我怎么能指定这个（这将被发送给另一个人）。所以路径不能在我的系统上，它也必须位于JAR中。

package main;

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;

javax.sound.sampled.AudioSystem;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

import sun.audio.AudioPlayer;
import sun.audio.AudioStream;

public class Main extends JFrame {
/**
 * 
 */
private static final long serialVersionUID = 1L;
private JPanel contentPane;

/**
 * Launch the application.
 */
public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                Main frame = new Main();
                frame.setVisible(true);
                PlaySound();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

/**
 * Create the frame.
 */
public static void PlaySound() {
    InputStream in;
    try {
        in = new FileInputStream(new File("/audio/Happy_Happy_Birthday.wav"));
        AudioStream audios = new AudioStream(in);
        AudioPlayer.player.start(audios);
    } catch (Exception e) {
        JOptionPane.showMessageDialog(null, e);

    }

}

public Main() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 717, 508);
    contentPane = new JPanel() {
        /**
         * 
         */
        private static final long serialVersionUID = 1L;

        public void paintComponent(Graphics g) {
            Image img = Toolkit.getDefaultToolkit().getImage(
                    Main.class.getResource("/images/happy_birthday.jpg"));
            g.drawImage(img, 0, 0, this.getWidth(), this.getHeight(), this);
        }
    };
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    contentPane.setLayout(new BorderLayout(0, 0));
    setContentPane(contentPane);
}
}

Answer 1

使用URL而不是File加载剪辑。到部署时，这些资源可能会成为embedded-resource。在这种情况下，必须由URL而不是File访问资源。有关标记的info page，请参阅URL。
使用javax.sound.sampled.Clip播放声音（与sun.audio包中的未记录的课程相对）。有关工作来源，请参阅Java Sound info. page。

Answer 2

InputStream in;
    try {
        in = new FileInputStream(new File("Jock_Jams_-_Are_You_Ready_For_This.wav"));
        AudioStream audios = new AudioStream(in);
        AudioPlayer.player.start(audios);
    } catch (Exception e) {
        JOptionPane.showMessageDialog(null, e);

    }

我在while循环之外使用它，只要您不介意它无法停止，它就会起作用。
