如何用java执行批处理文件（bat），不要小看，试试再说，谢谢！

public static boolean spawnExe (String batch_file, boolean waitOnClose)
    {
        boolean retval = false;
        try {
            String osName = System.getProperty("os.name");
            String[] cmd = new String[3];

            // Win9X
            if (osName.equals(WIN_95) ||
                osName.equals(WIN_98) ||
                osName.startsWith(WIN_3X) ||
                osName.startsWith(WIN_FW) ) {
                cmd[0] = "command.com" ;
                cmd[1] = "/C" ;
                cmd[2] = batch_file;
                retval = true;
            }
            // W2K or greater
            else if ( osName.startsWith(WIN) ) {
                cmd[0] = "cmd.exe" ;
                cmd[1] = "/C" ;
                cmd[2] = batch_file;
                retval = true;
            }

            if (retval) {
                Runtime rt = Runtime.getRuntime();
                Process proc = rt.exec(cmd);

                if (waitOnClose)
                  proc.waitFor();
            }
        } catch (Exception e) {
            e.printStackTrace();
            retval = false;
        }
        return retval;
    }

我试了， 可以啊！


加上这一段： 可以看执行的结果输出。

InputStream in = proc.getInputStream();
                
BufferedReader line = new BufferedReader(new InputStreamReader(in));
String l = line.readLine();
    while (l!=null)
          {
          System.out.println(l);
          l = line.readLine();
         }
        
                in.close();
