在Java中将编码过滤器添加到JFileChooser

Question

如何在我的JFileChooser保存对话框中添加编码选项“UTF-8”。

  JFileChooser fileChooser = new JFileChooser();
  FileNameExtensionFilter filter1 = new FileNameExtensionFilter("TEXT", ".txt");

        fileChooser.setFileFilter(filter1);
        fileChooser.setDialogTitle("Specify a file to save"); 
              int returnVal = fileChooser.showSaveDialog(null);
              if ( returnVal == JFileChooser.APPROVE_OPTION )
               {

                    File file = fileChooser.getSelectedFile();
               //do something
               }

使用标准Java：

String aString = "Test\nWithNewline";
try {
    Writer out = new BufferedWriter(new OutputStreamWriter(
                      new FileOutputStream("outfilename"), "UTF-8"));
    out.write(aString);
    out.close();
} catch (IOException e1) {
    e1.printStackTrace();
}

使用Apache Commons：

File f = new File("outfilename"); 
FileUtils.writeStringToFile(f, aString, "UTF-8");
