java调python文件(使用conda的环境)

:: windows切换环境
activate gdal3.3.1

// 先切换环境再执行脚本
String cmd = "D:\\ars\\m2m\\activate.cmd && " ;   // 切换环境
      += " python D:\\ars\\m2m\\tvdi.py" ;    // 执行脚本
      += " --LC08_fn --shape_fn" ;        // 传递参数
logger.info("-------------------> " + cmd + " <-------------------");
// 执行
Process p = Runtime.getRuntime().exec(cmd);
String read, result = "";
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream(), "gbk"));
while ((read = in .readLine()) != null) {
    result += read;
}
p.waitFor();
// 返回结果
logger.info("-------------------> " + result + " <-------------------");
