Question

我试图从 Java 的外部编辑中打开文件, 但是当我运行我的源代码时, 什么都没有发生。我使用 JRE 1. 6, 我的调值系统是 Windows 7 。这是我的源代码 :

Desktop desktop = null;
if (Desktop.isDesktopSupported()) {
  desktop = Desktop.getDesktop();
}

 desktop.edit(new File("D:\Document.rtf"));

Answer 1

还应开展以下工作:

Runtime.getRuntime().exec( "cmd /C D:\Document.rtf" );

或

    Runtime run = Runtime.getRuntime();
    String lcOSName = System.getProperty("os.name").toLowerCase();
    boolean MAC_OS_X = lcOSName.startsWith("mac os x");
    if (MAC_OS_X) {
        run.exec("open " + file);
    } else {
        //run.exec("cmd.exe /c start " + file); //win NT, win2000
        run.exec("rundll32 url.dll, FileProtocolHandler " + path);
    }

Answer 2

did you read API

< a href=>"http://docs.oracle.com/javase/6/docs/api/java/awt/Desktop.html#edit%28java.io.File%29" rel=“nofollow” > 公共无效编辑(档案文件)

启动相关编辑器应用程序并打开文件进行编辑。

Parameters: file - the file to be opened for editing Throws: NullPointerException - if the specified file is null IllegalArgumentException - if the specified file doesn t exist UnsupportedOperationException - if the current platform does not support the Desktop.Action.EDIT action IOException - if the specified file has no associated editor, or the associated application fails to be launched SecurityException - if a security manager exists and its SecurityManager.checkRead(java.lang.String) method denies read access to the file, or SecurityManager.checkWrite(java.lang.String) method denies write access to the file, or it denies the AWTPermission("showWindowWithoutWarningBanner") permission, or the calling thread is not allowed to create a subprocess See Also: AWTPermission

并打印 StackTrace 的
