要让照片随机播放,需要把照片名改成比如photo1.jpg,photo2.jpg,photo3.jpg...的有序号顺序排列的文件名,
创新互联坚持“要么做到，要么别承诺”的工作理念，服务领域包括：成都网站建设、网站建设、企业官网、英文网站、手机端网站、网站推广等服务，满足客户于互联网时代的成安网站设计、移动媒体设计的需求，帮助企业找到有效的互联网解决方案。努力成为您成熟可靠的网络建设合作伙伴！
然后把改名后的照片文件放到你的项目名的目录下,比如你的项目名叫"slideshow",你就把照片文件放到slideshow文件夹下.
最后把下面的Java程序拷贝到你的项目中,把有DD类名的地方改成你的类名,就行了.
完整的让一些照片在JFrame窗体里自动随机播放的幻灯片程序如下
(我用的图片文件是photo1.jpg,photo2.jpg,photo3.jpg,注意事项在注释中注明
import java.awt.Graphics;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
public class DD extends JFrame implements Runnable{
ImageIcon ii=new ImageIcon("photo1.jpg");//这里换成你的图片文件名,放在你的项目名的文件夹中
DD(){
super("Slide");
setSize(400, 400);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
public void paint(Graphics g){
super.paint(g);
g.drawImage(ii.getImage(),0,0,400,400,null);
}
@Override
public void run() {
while(true){
try {
Thread.sleep(500);//这里是幻灯片播放间隔的时间,这里为500毫秒=0.5秒
} catch (InterruptedException e) {
e.printStackTrace();
}
int i=(int)(Math.random()*3)+1;//这里是产生从1-3的随机数,如果你有6个图片文件,把3改成6就是从1-6的随机数了.
ii=new ImageIcon("photo"+i+".jpg");//这里调用你的图片文件,如果你有6个图片文件,改成从1-6的文件名方便调用
this.repaint();
}
}
public static void main(String[] args) {
DD d=new DD();
Thread t=new Thread(d);
t.start();
}
}

把你的图片地址 在jsp加载的时候 循环上去 就可以了 如果可以 记得给分哦
