java 调用url打开浏览器显示网页

发现新浪微博提供的API中有个类BareBonesBrowserLaunch，它的函数openURL可以实现打开传递的url参数，调用浏览器程序，打开url。

public class BareBonesBrowserLaunch {    public static void openURL(String url) {        try {            browse(url);        } catch (Exception e) {            JOptionPane.showMessageDialog(null, "Error attempting to launch web browser:\n" + e.getLocalizedMessage());        }    }    private static void browse(String url) throws ClassNotFoundException, IllegalAccessException,            IllegalArgumentException, InterruptedException, InvocationTargetException, IOException,            NoSuchMethodException {        String osName = System.getProperty("os.name", "");        if (osName.startsWith("Mac OS")) {            Class fileMgr = Class.forName("com.apple.eio.FileManager");            Method openURL = fileMgr.getDeclaredMethod("openURL", new Class[] { String.class });            openURL.invoke(null, new Object[] { url });        } else if (osName.startsWith("Windows")) {            Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);        } else { // assume Unix or Linux            String[] browsers = { "firefox", "opera", "konqueror", "epiphany", "mozilla", "netscape" };            String browser = null;            for (int count = 0; count < browsers.length && browser == null; count++)                if (Runtime.getRuntime().exec(new String[] { "which", browsers[count] }).waitFor() == 0)                    browser = browsers[count];            if (browser == null)                throw new NoSuchMethodException("Could not find web browser");            else                Runtime.getRuntime().exec(new String[] { browser, url });        }    }   }
