Java程序打开浏览器和文件夹

Java程序打开浏览器和文件夹

(1)打开网址

Java代码  

1. //启用系统默认浏览器来打开网址。  
2.         try {  
3.             URI uri = new URI("file:///"+fileFullPath.replaceAll("\\\\", "/"));  
4.             Desktop.getDesktop().browse(uri);  
5.         } catch (URISyntaxException e2) {  
6.             e2.printStackTrace();  
7. //            GUIUtil23.errorDialog(e2);  
8.             ToastMessage.toast(e2.getMessage(),3000,Color.red);  
9.         } catch (IOException e2) {  
10.             e2.printStackTrace();  
11. //            GUIUtil23.errorDialog(e2);  
12.             ToastMessage.toast(e2.getMessage(),3000,Color.red);  
13.         }  

(2)打开文件所在文件夹

Java代码  

1. String pathStr=this.tf.getText();  
2.             if(!ValueWidget.isNullOrEmpty(pathStr)){  
3.                 FileUtils.open_directory(SystemHWUtil.getParentDir(pathStr));  
4.             }  

FileUtils.open_directory实现体为:

Java代码  

1. /*** 
2.      *  
3.      * @param folder 
4.      *            : directory 
5.      */  
6.     public static void open_directory(Object folderObj) {  
7.         if (ValueWidget.isNullOrEmpty(folderObj)) {  
8.             return;  
9.         }  
10.         File file = null;  
11.         /*if (folderObj instanceof JTextField) { 
12.             JTextField tf = (JTextField) folderObj; 
13.             file = new File(tf.getText()); 
14.         } else */if (folderObj instanceof String) {  
15.             file = new File((String) folderObj);  
16.         } else {  
17.             file = (File) folderObj;  
18.         }  
19.         if (!file.exists()) {  
20.             return;  
21.         }  
22.         Runtime runtime = null;  
23.         try {  
24.             runtime = Runtime.getRuntime();  
25.             if (SystemHWUtil.isWindows) {  
26.                 runtime.exec("cmd /c start explorer " + file.getAbsolutePath());  
27.             } else {  
28.                 runtime.exec("nautilus " + file.getAbsolutePath());  
29.   
30.             }  
31.         } catch (IOException ex) {  
32.             ex.printStackTrace();  
33.         } finally {  
34.             if (null != runtime) {  
35.                 runtime.runFinalization();  
36.             }  
37.         }  
38.     }  

(3)使用notepad打开txt文件

Java代码  

1. final String pathStr=this.tf.getText();  
2.             if(!ValueWidget.isNullOrEmpty(pathStr)){  
3.                 new Thread(new Runnable() {  
4.                     @Override  
5.                     public void run() {  
6.                         String result;  
7.                         try {  
8.                             result = CMDUtil.execute(new String[]{"cmd", "/c", "notepad", pathStr}, null, null);  
9.                             System.out.println(result);  
10.                         } catch (IOException ex) {  
11.                             ex.printStackTrace();  
12.                         }  
13.                     }  
14.                 }).start();  
15.             }  

 CMDUtil.execute实现如下:

Java代码  

1. /*** 
2.      *  
3.      * @param command 
4.      * @param cmdFolder : 命令的路径 
5.      * @param charset 
6.      * @return 
7.      * @throws IOException 
8.      */  
9.     public static String execute(String[]command,String cmdFolder,String charset) throws IOException{  
10.          BufferedReader reader = null;  
11.          Process p = null;  
12.          String errorInputStr = null;  
13.             try  
14.             {  
15. //              String commandFolder=;  
16.                 if(ValueWidget.isNullOrEmpty(charset)){  
17.                     charset=SystemHWUtil.CURR_ENCODING;  
18.                 }  
19.                 if(ValueWidget.isNullOrEmpty(cmdFolder)){  
20.                     p = Runtime.getRuntime().exec(command);  
21.                 }else{  
22.                     File cmdFolder2=null;  
23.                     if(!ValueWidget.isNullOrEmpty(cmdFolder)){  
24.                         cmdFolder2=new File(cmdFolder/*命令的所在目录*/);  
25.                         p = Runtime.getRuntime().exec(command, null,cmdFolder2/*命令的路径*/);//)  
26.                     }else{  
27.                         p = Runtime.getRuntime().exec(command, null);//)  
28.                     }  
29.                       
30.                       
31.                 }  
32.                 reader = new BufferedReader(new InputStreamReader(p  
33.                         .getInputStream(),charset));  
34.                 errorInputStr=FileUtils.getFullContent4(p.getErrorStream(),charset);  
35.                 if(!ValueWidget.isNullOrEmpty(errorInputStr)){  
36.                     System.out.println("error:"+errorInputStr);  
37.                 }  
38.                 StringBuilder sb = new StringBuilder();  
39.                 String readedLine = null;  
40.                 try  
41.                 {  
42.                     while ((readedLine = reader.readLine()) != null)  
43.                     {  
44.                         sb.append(readedLine);  
45.                         sb.append("\r\n");  
46.                     }  
47.                 }  
48.                 catch (IOException e)  
49.                 {  
50.                     e.printStackTrace();  
51.                 }  
52.                 finally  
53.                 {  
54.                     try  
55.                     {  
56.                         reader.close();  
57.                         p.destroy();  
58.                     }  
59.                     catch (IOException e)  
60.                     {  
61.                         e.printStackTrace();  
62.                     }  
63.                 }  
64.                 String content = sb.toString();  
65.                 System.out.println(content);  
66.             }  
67.             catch (IOException e)  
68.             {  
69.                 e.printStackTrace();  
70.                 throw e;  
71.             }  
72.             return errorInputStr;  
73.     }
