Java 6解決方案:

public static void launchFile(File file) {

if (!Desktop.isDesktopSupported())

return;

Desktop dt = Desktop.getDesktop();

try {

dt.open(file);

} catch (IOException ex) {

// this is sometimes necessary with files on other servers ie

// \\xxx\xxx.xls

launchFile(file.getPath());

}

}

// this can launch both local and remote files

public static void launchFile(String filePath) {

if (filePath == null || filePath.trim().length() == 0)

return;

if (!Desktop.isDesktopSupported())

return;

Desktop dt = Desktop.getDesktop();

try {

dt.browse(getFileURI(filePath));

} catch (Exception ex) {

ex.printStackTrace();

}

}

// generate uri according to the filePath

private static URI getFileURI(String filePath) {

URI uri = null;

filePath = filePath.trim();

if (filePath.indexOf("http") == 0 || filePath.indexOf("\\") == 0) {

if (filePath.indexOf("\\") == 0){

filePath = "file:" + filePath;

filePath = filePath.replaceAll("#", "%23");

}

try {

filePath = filePath.replaceAll(" ", "%20");

URL url = new URL(filePath);

uri = url.toURI();

} catch (MalformedURLException ex) {

ex.printStackTrace();

} catch (URISyntaxException ex) {

ex.printStackTrace();

}

} else {

File file = new File(filePath);

uri = file.toURI();

}

return uri;

}

這個答案在bug報告中,但我已經編輯了它,以便在有哈希值時修復。
