Java调用exe程序

 

    String exePath= "D:\\Xftp6\\Xftp.exe";
    BufferedReader br = null;
    BufferedReader brError;
    String line = null;
    try {
        /**
        * String cmd = "D:\\Xftp6\\Xftp.exe";
        * 方式一：使用Runtime.getRuntime().exec()；
        * 执行exe cmd可以为字符串(exe存放路径)也可为数组,
        * 调用exe时需要传入参数时，可以传数组调用(参数有顺序要求)
        * String[] cmd ={"exe绝对路径", "param1", "param2", "param3"};
        * Runtime.getRuntime().exec(cmd);
        */
        //方式二：
        Process p = new ProcessBuilder(exePath).start();
        br = new BufferedReader(new InputStreamReader(p.getInputStream()));
        brError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
        while ((line = br.readLine()) != null || (line = brError.readLine()) != null) {
            //输出exe输出的信息以及错误信息
            log.info(line);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (br != null) {
            try {
                br.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
