Java通过MultipartFile文件上传形式动态调用python脚本、动态维度字段数据输出

环境:需要java环境、python环境

先看执行效果:

python脚本:

运行结果:

Postman入参数据

file:直接上传python脚本文件

query:自定义返回的维度(我这里是三个维度)

话不多说直接上代码！！！

    public List>> pypy(MultipartFile file,String query) throws IOException {
        //把用户上传的python脚本文件存放到指定目录
        file.transferTo(new File("D:\python\" + file.getOriginalFilename()));
        //定义python程序路径
        String pythonExe = "D:/install/python.exe ";
        //定义脚本路径
        String scriptPath = "D:/python/" + file.getOriginalFilename();
        Process process;
        BufferedReader bufferedReader;
        try {
            List>> map = new ArrayList<>();
            process = Runtime.getRuntime().exec(pythonExe + scriptPath);
            bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream(), Charset.forName("GBK")));
            String res;
            while ((res = bufferedReader.readLine()) != null) {
                List> mapList = new ArrayList<>();
                String[] split = query.split(",");
                int a = 0;
                for (String s : split) {
                    Map m = new HashMap();
                    m.put(s, res.split(",")[a++]);
                    mapList.add(m);
                }
                map.add(mapList);
            }
            return map;
        } catch (IOException e) {
            List>> map = new ArrayList<>();
            return map;
        }
    }
