参考以下实现方式

public static String runLinuxCommand(String command) {
        LOG.info("runLinuxCommand command: {}", command);
        Process ps = null;
        BufferedReader bufIn = null;
        BufferedReader bufError = null;
        try {
            ps = Runtime.getRuntime().exec(command);
            ps.waitFor();

            bufIn = new BufferedReader(new InputStreamReader(ps.getInputStream(), "utf-8"));
            bufError = new BufferedReader(new InputStreamReader(ps.getErrorStream(), "utf-8"));

            // 读取输出 result是shell中的输出
            StringBuilder result = new StringBuilder();
            String line;
            while ((line = bufIn.readLine()) != null || (line = bufError.readLine()) != null) {
                result.append(line);
            }

            LOG.info("runLinuxCommand result: {}", result);
            return result.toString();
        } catch (Exception e) {
            LOG.error("runLinuxCommand error", e);

            return e.getMessage();
        } finally {
            close(bufError);
            close(bufIn);
            ps.destroy();
        }

    }




    private static void close(Closeable closeable) {
        if (null != closeable) {
            try {
                closeable.close();
            } catch (IOException e) {
                LOG.error("close closeable obj error", e);
            }
        }
    }
