Java程序打开浏览器和文件夹

(1)打开网址

   Java代码  
    
  
//启用系统默认浏览器来打开网址。  
        try {  
            URI uri = new URI("file:///"+fileFullPath.replaceAll("\\\\", "/"));  
            Desktop.getDesktop().browse(uri);  
        } catch (URISyntaxException e2) {  
            e2.printStackTrace();  
//            GUIUtil23.errorDialog(e2);  
            ToastMessage.toast(e2.getMessage(),3000,Color.red);  
        } catch (IOException e2) {  
            e2.printStackTrace();  
//            GUIUtil23.errorDialog(e2);  
            ToastMessage.toast(e2.getMessage(),3000,Color.red);  
        }  

(2)打开文件所在文件夹

   Java代码  
    
  
String pathStr=this.tf.getText();  
            if(!ValueWidget.isNullOrEmpty(pathStr)){  
                FileUtils.open_directory(SystemHWUtil.getParentDir(pathStr));  
            }  

FileUtils.open_directory实现体为:

   Java代码  
    
  
/*** 
     *  
     * @param folder 
     *            : directory 
     */  
    public static void open_directory(Object folderObj) {  
        if (ValueWidget.isNullOrEmpty(folderObj)) {  
            return;  
        }  
        File file = null;  
        /*if (folderObj instanceof JTextField) { 
            JTextField tf = (JTextField) folderObj; 
            file = new File(tf.getText()); 
        } else */if (folderObj instanceof String) {  
            file = new File((String) folderObj);  
        } else {  
            file = (File) folderObj;  
        }  
        if (!file.exists()) {  
            return;  
        }  
        Runtime runtime = null;  
        try {  
            runtime = Runtime.getRuntime();  
            if (SystemHWUtil.isWindows) {  
                runtime.exec("cmd /c start explorer " + file.getAbsolutePath());  
            } else {  
                runtime.exec("nautilus " + file.getAbsolutePath());  
  
            }  
        } catch (IOException ex) {  
            ex.printStackTrace();  
        } finally {  
            if (null != runtime) {  
                runtime.runFinalization();  
            }  
        }  
    }  

(3)使用notepad打开txt文件

   Java代码  
    
  
final String pathStr=this.tf.getText();  
            if(!ValueWidget.isNullOrEmpty(pathStr)){  
                new Thread(new Runnable() {  
                    @Override  
                    public void run() {  
                        String result;  
                        try {  
                            result = CMDUtil.execute(new String[]{"cmd", "/c", "notepad", pathStr}, null, null);  
                            System.out.println(result);  
                        } catch (IOException ex) {  
                            ex.printStackTrace();  
                        }  
                    }  
                }).start();  
            }  

CMDUtil.execute实现如下:

   Java代码  
    
  
/*** 
     *  
     * @param command 
     * @param cmdFolder : 命令的路径 
     * @param charset 
     * @return 
     * @throws IOException 
     */  
    public static String execute(String[]command,String cmdFolder,String charset) throws IOException{  
         BufferedReader reader = null;  
         Process p = null;  
         String errorInputStr = null;  
            try  
            {  
//              String commandFolder=;  
                if(ValueWidget.isNullOrEmpty(charset)){  
                    charset=SystemHWUtil.CURR_ENCODING;  
                }  
                if(ValueWidget.isNullOrEmpty(cmdFolder)){  
                    p = Runtime.getRuntime().exec(command);  
                }else{  
                    File cmdFolder2=null;  
                    if(!ValueWidget.isNullOrEmpty(cmdFolder)){  
                        cmdFolder2=new File(cmdFolder/*命令的所在目录*/);  
                        p = Runtime.getRuntime().exec(command, null,cmdFolder2/*命令的路径*/);//)  
                    }else{  
                        p = Runtime.getRuntime().exec(command, null);//)  
                    }  
                      
                      
                }  
                reader = new BufferedReader(new InputStreamReader(p  
                        .getInputStream(),charset));  
                errorInputStr=FileUtils.getFullContent4(p.getErrorStream(),charset);  
                if(!ValueWidget.isNullOrEmpty(errorInputStr)){  
                    System.out.println("error:"+errorInputStr);  
                }  
                StringBuilder sb = new StringBuilder();  
                String readedLine = null;  
                try  
                {  
                    while ((readedLine = reader.readLine()) != null)  
                    {  
                        sb.append(readedLine);  
                        sb.append("\r\n");  
                    }  
                }  
                catch (IOException e)  
                {  
                    e.printStackTrace();  
                }  
                finally  
                {  
                    try  
                    {  
                        reader.close();  
                        p.destroy();  
                    }  
                    catch (IOException e)  
                    {  
                        e.printStackTrace();  
                    }  
                }  
                String content = sb.toString();  
                System.out.println(content);  
            }  
            catch (IOException e)  
            {  
                e.printStackTrace();  
                throw e;  
            }  
            return errorInputStr;  
    }
