Java执行cmd命令

因业务需求，需要在通过前端调用服务端接口来执行cmd命令，具体操作如下

 

    public String execCmdOrder(String cmdCommand) {

        if (StringUtils.isEmpty(cmdCommand)){
            throw new RuntimeException("需要执行的命令不可以为空");
        }

        /*if (***其他判断条件***){
            throw new RuntimeException("不满足判断条件的原因");
        }*/

        //组装cmd 命令
        String cmd= cmdCommand ;
        BufferedReader br=null;
        Process process=null;
        //执行命令结果
        StringBuilder result = null;
        try {
            //执行cmd命令
            process=Runtime.getRuntime().exec(cmd);
            //获取cmd命令的输出结果
            br=new BufferedReader(new InputStreamReader(process.getInputStream()));
            result= new StringBuilder();
            String tmp;
            //组装命令执行结束后返回值
            while ((tmp= br.readLine())!=null){
                result.append(tmp).append("\n");
            }
            process.waitFor();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }finally {
            if (br!=null){
                try {
                    br.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if (process != null) {
                process.destroy();
            }
            System.out.println("执行命令结束以后控制台返回结果为 ：" + result);
        }
        return result.toString();
    }
