下面的示例展示了如何读取URL以在基于swing的应用程序中显示其页面。
使用以下API -
JEditorPane- 创建一个显示HTML内容的编辑框。JEditorPane.setPage(String url)- 从传递和显示的URL获取HTML。
示例
package com.yiibai.swingdemo;
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.LayoutManager;
import java.io.IOException;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
public class SwingTester {
public static void main(String[] args) {
createWindow();
}
private static void createWindow() {
JFrame frame = new JFrame("Swing读取URL显示页面");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
createUI(frame);
frame.setSize(560, 450);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
private static void createUI(final JFrame frame){
JPanel panel = new JPanel();
LayoutManager layout = new FlowLayout();
panel.setLayout(layout);
JEditorPane jEditorPane = new JEditorPane();
jEditorPane.setEditable(false);
try {
jEditorPane.setPage("http://www.kaops.com");
} catch (IOException e) {
jEditorPane.setContentType("text/html");
jEditorPane.setText("<html>Page not found.</html>");
}
JScrollPane jScrollPane = new JScrollPane(jEditorPane);
jScrollPane.setPreferredSize(new Dimension(540,400));
panel.add(jScrollPane);
frame.getContentPane().add(panel, BorderLayout.CENTER);
}
}
执行上面示例代码，得到以下结果：
