java - 打开文件名中包含外来字符的文件

Question

我正在为下个月的考试开发一个小型应用程序。在此应用程序中，用户可以上传与其名称匹配的文件。

不幸的是，在丹麦，我们有一些外来字符 (ÆØÅæøå)，我的代码将无法打开包含这些字符的文件。

是否有解决方法可以让我使用这些文件名？

这是打开文件的代码:

Desktop.getDesktop().open(new File("kontrakt/" + getStuderende().getKontrakt()));

异常(exception)情况:

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: The file: kontrakt/5_Bjørnen-Bjørn-kontrakt.docx doesn't exist.

Answer 1

该代码可以在 Windows 中运行。但是，本主题中使用的 OSX 操作系统显然不支持此功能。

这很好用

package others;

    import java.awt.Desktop;
    import java.io.File;

    public class A {

        public static void main(String[] args) throws Exception{


            Desktop.getDesktop().open(new File("c://5_Bjørnen-Bjørn-kontrakt.docx"));

        }

    }

尝试打印您从 getStuderende().getKontrakt() 方法获得的内容

检查它是否与您正在打开的文件相同。
