java调用第三方应用程序

1. java调用第三方应用使用 ProcessBuilder 对象来调用   

例子位置:

  xc-service-manage-media-processor/test/TestProcessBuilder

 

//建立processBuilder对象
        ProcessBuilder processBuilder = new ProcessBuilder();
        //设置第三方应用程序的命令
//        processBuilder.command("ping","127.0.0.1");
        processBuilder.command("ipconfig");

        //将标准输入流和错误流合并
        processBuilder.redirectErrorStream(true);
        //启动一个进程（至关于在命令行中输入命令）
        Process process = processBuilder.start();

        //经过标准输入流来拿到正常和错误的信息
        InputStream inputStream = process.getInputStream();

        //转成字符流
        InputStreamReader reader = new InputStreamReader(inputStream,"gbk");
        //缓冲
        char[] chars = new char[1024];
        int len = -1;
        while ((len = reader.read(chars))!=-1){
            String string = new String(chars,0,len);
            System.out.println(string);
        }
        inputStream.close();
        reader.close();
