Java调用shell脚本解决传参和权限问题的方法

 /**   * 执行shell   * @param execCmd 使用命令 或 脚本标志位   * @param para 传入参数   */  private static void execShell(boolean execCmd, String... para) {    StringBuffer paras = new StringBuffer();    Arrays.stream(para).forEach(x -> paras.append(x).append(" "));    try {      String cmd = "", shpath = "";      if (execCmd) {        // 命令模式        shpath = "echo";      } else {      //脚本路径        shpath = "/Users/yangyibo/Desktop/callShell.sh";      }      cmd = shpath + " " + paras.toString();      Process ps = Runtime.getRuntime().exec(cmd);      ps.waitFor();      BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));      StringBuffer sb = new StringBuffer();      String line;      while ((line = br.readLine()) != null) {        sb.append(line).append("/n");      }      String result = sb.toString();      System.out.println(result);    } catch (Exception e) {      e.printStackTrace();    }  }
