java 执行外部命令获取其输出

Posted 2021-09-09 -SOLO-

  static void showInfo (InputStream inputStream) {
        BufferedReader bufferedReader = null;
        try {
            bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "gbk"));
            String line = null;
            while ((line = bufferedReader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (bufferedReader != null) {
                try {
                    bufferedReader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    };

使用

Process process = Runtime.getRuntime().exec("ping baidu.com");
showInfo (process.getInputStream());
process.waitFor();
System.out.println(process.exitValue());
