Open a file with an external application on Java
提问by Mercurious
How do you open a file from a java application when you do not know which application the file is associated with. Also, because I'm using Java, I'd prefer a platform independent solution.
当您不知道文件与哪个应用程序关联时，如何从 Java 应用程序打开文件。另外，因为我使用的是 Java，所以我更喜欢独立于平台的解决方案。

With JDK1.6, the java.awt.Desktopclass can be useful.
对于 JDK1.6，java.awt.Desktop该类很有用。
public static void open(File document) throws IOException {
Desktop dt = Desktop.getDesktop();
dt.open(document);
}

You could hack something together with a bat file on Windows and equivalent on Unix, but that wouldn't be that fun.
你可以在 Windows 上用 bat 文件和 Unix 上的等效文件一起破解一些东西，但这不会那么有趣。
I think your best bet would be the JDesktop Integration Components (JDIC). In particular, the Desktopclass has exactly the method you're looking for.
我认为您最好的选择是JDesktop 集成组件 (JDIC)。特别是，Desktop类具有您正在寻找的方法。
EDIT: Apparently, I'm behind the times because this has been integrated into Java 1.6. In any case, if you're working in an earlier Java, it may still be useful.
编辑：显然，我落后于时代，因为它已集成到 Java 1.6 中。无论如何，如果您使用的是较早的 Java，它可能仍然有用。

Summary
概括
It would look something like this:
它看起来像这样：
Runtime.getRuntime().exec( getCommand( file ) );
public String getCommand( String file ){
// Depending on the platform could be
//String.format("gnome-open %s", fileName)
//String.format("open %s", fileName)
//String.format("cmd /c start %s", fileName)
// etc.
}
