java中调用本地脚本

java中可以调用本地脚本,也可以远程调用shell脚本,但是java调用远程脚本不安全,一般不这么做,那该怎么调用呢?
建议在本地写个脚本调用远程脚本,在java程序中调用本地脚本,具体代码:

private int execShell(String shellPath, String... params) {
        StringBuilder command = new StringBuilder(shellPath).append(" ");
        for (String param : params) {
            command.append(param).append(" ");
        }

        BufferedReader br = null;
        StringBuilder sb = null;
        try {
            Process process = Runtime.getRuntime().exec(command.toString());
            process.waitFor();

            br = new BufferedReader(new InputStreamReader(process.getInputStream()));
            sb = new StringBuilder();
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line);
            }
        } catch (Exception e) {
            LOG.error("execShell() error, shellPath: {}, params: {}", shellPath, params, e);
            return -2;
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return "".equals(sb.toString()) ? 0 : Integer.parseInt(sb.toString());
    }

注意:如果脚本执行成功,process.waitFor()会返回0状态码;如果脚本执行出错,本根据不同的错误返回不同的状态码,此时需要使用流获取到脚本返回的状态
