通过相对
引用链接资源（例如CSS或图像）的Jar文件中的HTML即可正常工作。
例如
本示例从
Jar中加载HTML（具有相对于图像的引用）。
import javax.swing.*;import java.net.URL;class ShowHtml { public static void main(String[] args) { final String address = "jar:http://pspre.org/jh/hs/object.jar!/popup_contents.html"; SwingUtilities.invokeLater(new Runnable() { public void run() { try { URL url = new URL(address); JEditorPane jep = new JEditorPane(url); Jframe f = new Jframe("Show HTML in Jar"); f.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); f.add(new JScrollPane(jep)); f.pack(); f.setSize(400,300); f.setLocationByPlatform(true); f.setVisible(true); } catch(Exception e) { e.printStackTrace(); } } }); }}Screenshot

E.G. 2
对于动态创建的HTML，JRE可能会将类文件的
位置用作HTML的假定位置。但是，为了消除所有疑问，我们可以在中
指定
base元素
head。
import javax.swing.*;class HtmlUsingbase { public static void main(String[] args) { final String htmlContent = "<html>" + "<head>" + "<base href='http://www.gravatar.com/'>" + "</head>" + "<body>" + "<h1>Image path from base</h1>" + "<img src='avatar/a1ab0af4997654345d7a9" + "49877f8037e?s=128&d=identicon&r=PG'" + " width='128' height='128'>" + "</body>" + "</html>"; SwingUtilities.invokeLater(new Runnable() { public void run() { JLabel label = new JLabel(htmlContent); JOptionPane.showMessageDialog(null, label); } }); }}
