String filename = file.getName();

String ext = FileUtil.getExtension(filename);

String name = FileUtil.getName(filename);

name = RegExpUtil.filterCommandLineSpecialChar(name);

String command = "cmd /c start "+name+ext;

Process process = Runtime.getRuntime().exec(command,null,dir);

int v = process.waitFor();

System.out.println(v);

} catch (Exception e) {

//e.printStackTrace();

System.out.println(e.getMessage());

}

}

文件名處理

public static String filterCommandLineSpecialChar(String s){

String regexp = "[\\pP\\pZ\\pS]+";

Pattern pattern = Pattern.compile(regexp, Pattern.CASE_INSENSITIVE);

Matcher matcher = pattern.matcher(s);

StringBuffer sb = new StringBuffer();

while (matcher.find()) {

String p = matcher.group();

matcher.appendReplacement(sb, "\""+p+"\"");

}

matcher.appendTail(sb);

return sb.toString();

}
