Java调用浏览器

J2SE 6 新增了 java.awt.Desktop ，这套桌面 API 使用你的主机操作系统的文件关联以启动与特定文件类型相关联的应用程序。调用本地浏览器非常方便，且跨平台适用。

1. public   static   void  runBroswer(String webSite) {  
2.         try  {  
3.             Desktop desktop = Desktop.getDesktop();  
4.             if  (desktop.isDesktopSupported() && desktop.isSupported(Desktop.Action.BROWSE)) {  
5.                 URI uri = new  URI(webSite);  
6.                 desktop.browse(uri);  
7.             }  
8.         } catch  (IOException ex) {  
9.             ex.printStackTrace();  
10.         } catch  (URISyntaxException ex) {  
11.             ex.printStackTrace();  
12.         }  
13.     }  

public static void runBroswer(String webSite) { try { Desktop desktop = Desktop.getDesktop(); if (desktop.isDesktopSupported() && desktop.isSupported(Desktop.Action.BROWSE)) { URI uri = new URI(webSite); desktop.browse(uri); } } catch (IOException ex) { ex.printStackTrace(); } catch (URISyntaxException ex) { ex.printStackTrace(); } }

J2SE 5及之前可使用以下代码

view plain copy to clipboard print ?

1. public   static   void  openURL(String url) {  
2.         String osName = System.getProperty("os.name" );  
3.         try  {  
4.             if  (osName.startsWith( "Mac" )) { //Mac OS   
5.                 Class fileMgr = Class.forName("com.apple.eio.FileManager" );  
6.                 Method openURL = fileMgr.getDeclaredMethod("openURL" ,  
7.                         new  Class[]{String. class });  
8.                 openURL.invoke(null ,  new  Object[]{url});  
9.             } else   if  (osName.startsWith( "Windows" )) { //Windows   
10.                 Runtime.getRuntime().exec(  
11.                         "rundll32 url.dll,FileProtocolHandler "  + url);  
12.             } else  {    //Unix   or   Linux   
13.                 String[] browsers = {"firefox" ,  "opera" ,  "konqueror" ,  
14.                     "epiphany" ,  "mozilla" ,  "netscape" };  
15.                 String browser = null ;  
16.                 for  ( int  count =  0 ; count < browsers.length && browser ==  null ; count++) {  
17.                     if  (Runtime.getRuntime().exec(  
18.                             new  String[]{ "which" , browsers[count]}).waitFor() ==  0 ) {  
19.                         browser = browsers[count];  
20.                     }  
21.                 }  
22.                 if  (browser ==  null ) {  
23.                     throw   new  Exception( "Could not find web browser" );  
24.                 } else  {  
25.                     Runtime.getRuntime().exec(new  String[]{browser, url});  
26.                 }  
27.             }  
28.         } catch  (Exception ex) {  
29.             ex.printStackTrace();  
30.         }  
31.     }  

public static void openURL(String url) { String osName = System.getProperty("os.name"); try { if (osName.startsWith("Mac")) {//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")) {//Windows Runtime.getRuntime().exec( "rundll32 url.dll,FileProtocolHandler " + url); } else { //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 Exception("Could not find web browser"); } else { Runtime.getRuntime().exec(new String[]{browser, url}); } } } catch (Exception ex) { ex.printStackTrace(); } }

如果是Applet则用以下代码直接访问链接

view plain copy to clipboard print ?

1. AppletContext context = getAppletContext();  
2. context.showDocument(new  URL( "http://blog.youkuaiyun.com/casularm" ),  "_blank" );
