接口方式输入命令得返回结果

    public AjaxResult doPost(HttpServletRequest request, HttpServletResponse response, String command) throws ServletException, IOException {
        // 设置响应内容类型 text/plain
//        response.setContentType("application/json");
        PrintWriter out = response.getWriter();

        try {
            // 要执行的命令（这里以"ls -l"为例）
            if(null == command){
                command = "ls -l";
            }

            // 执行命令并捕获输出
            Process process = Runtime.getRuntime().exec(command);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                log.info("执行结果: " + line);
                out.println(line);
                out.flush();
            }

            // 等待进程完成并检查退出值
            int exitCode = process.waitFor();
            if (exitCode != 0) {
                out.println("Command exited with error code: " + exitCode);
            }
        } catch (Exception e) {
            e.printStackTrace(out);
        } finally {
            out.close();
        }
       return AjaxResult.success();
    }

效果
