There's a few parts to this:
这有几个部分：
Setup the JEditorPane correctly
正确设置 JEditorPane
The JEditorPaneneeds to have the context type text/html, and it needs to be uneditable for links to be clickable:
在JEditorPane需要有上下文类型text/html，并且它需要不可编辑的链接，可以点击：
final JEditorPane editor = new JEditorPane();
editor.setEditorKit(JEditorPane.createEditorKitForContentType("text/html"));
editor.setEditable(false);
Add the links
添加链接
You need to add actual <a>tags to the editor for them to be rendered as links:
您需要向<a>编辑器添加实际标签，以便将它们呈现为链接：
editor.setText("<a href=\"http://www.google.com/finance?q=NYSE:C\">C</a>, <a href=\"http://www.google.com/finance?q=NASDAQ:MSFT\">MSFT</a>");
Add the link handler
添加链接处理程序
By default clicking the links won't do anything; you need a HyperlinkListenerto deal with them:
默认情况下，点击链接不会做任何事情；你需要一个HyperlinkListener来处理它们：
editor.addHyperlinkListener(new HyperlinkListener() {
public void hyperlinkUpdate(HyperlinkEvent e) {
if(e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
// Do something with e.getURL() here
}
}
});
How you launch the browser to handle e.getURL()is up to you. One way if you're using Java 6 and a supported platform is to use the Desktopclass:
您如何启动浏览器来处理e.getURL()取决于您。如果您使用的是 Java 6 并且受支持的平台，一种方法是使用Desktop该类：
if(Desktop.isDesktopSupported()) {
Desktop.getDesktop().browse(e.getURL().toURI());
}
