使用processBuilder执行shell命令并与之交互

private void  execReloadAll(){
        List<String> cmds = new ArrayList<String>();
        commands.add("ls");
        commands.add("-l");
        commands.add("/");
        ProcessBuilder pb=new ProcessBuilder(cmds);
        int exitCode = 0;
        try {
            Process process = pb.start();
            StreamGobbler streamGobbler =
                    new StreamGobbler(process.getInputStream(), System.out::println);
            Executors.newSingleThreadExecutor().submit(streamGobbler);
            exitCode = process.waitFor();
            log.info(" 执行成功");

            // 等待该进程执行完毕
            if (exitCode != 0) {
                // 如果进程运行结果不为0，表示进程是错误退出的
                // 获得进程实例的错误输出
                InputStream error = process.getErrorStream();
                log.info("加载失败：{}",error);
                throw new BizException(ErrorCode.IKE_LOAD_ALL_ERROR.getCode(),ErrorCode.IKE_LOAD_ALL_ERROR.getMsg());
            }
            // 获得进程实例的标准输出
            InputStream sdin = process.getInputStream();
            log.info("加载:{}",sdin);
        } catch (Exception e) {
            log.error("执行失败", e);
            throw new BizException(ErrorCode.getCode(),ErrorCode.getMsg());

        }
        assert exitCode == 0;
    }
