以前采用vb的webbrowser插件可以开发一个简单的浏览器，没想到java也具备这个功能。不过开发出来的看起来比较傻。看来不是java应该做的事情。或许是java还需要编写更多的代码来解析css和js
package com.javaer.examples.awt;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;
import java.io.IOException;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;
import javax.swing.text.html.HTMLDocument;
import javax.swing.text.html.HTMLFrameHyperlinkEvent;
public class WebView extends JFrame implements HyperlinkListener{
public WebView() throws Exception {
setSize(640, 480); setTitle(‘‘百度:中国最大的搜索引擎‘‘);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JEditorPane editorPane = new JEditorPane();
JScrollPane scrollPane = new JScrollPane(editorPane);
editorPane.setEditable(false);
//要能响应网页中的链接，则必须加上超链监听器
editorPane.addHyperlinkListener(this);
String path = ‘‘‘‘;
try
{
editorPane.setPage(path);
}
catch (IOException e)
{
System.out.println(‘‘读取页面 ‘‘ + path + ‘‘ 出错. ‘‘ + e.getMessage());
}
Container container = getContentPane();
container.setBackground(Color.WHITE);
//让editorPane总是填满整个窗体
container.add(scrollPane, BorderLayout.CENTER);
}
/**
* @param args
* @throws Exception
*/
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
WebView wv = new WebView();
wv.setVisible(true);
}
//超链监听器，处理对超级链接的点击事件，但对按钮的点击还捕获不到
@Override
public void hyperlinkUpdate(HyperlinkEvent e)
{
if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED)
{
JEditorPane pane = (JEditorPane) e.getSource();
if (e instanceof HTMLFrameHyperlinkEvent)
{
HTMLFrameHyperlinkEvent evt = (HTMLFrameHyperlinkEvent) e;
HTMLDocument doc = (HTMLDocument) pane.getDocument();
doc.processHTMLFrameHyperlinkEvent(evt);
}
else
{
try
{
pane.setPage(e.getURL());
}
catch (Throwable t)
{
t.printStackTrace();
}
}
}
}
}
