java 利用Runtime.getRuntime().exec()调用python脚本并传参

//TODO:执行python脚本
            System.out.println("start python");
            //需传入的参数
            String a = "aaa", b = "bbb", c = "ccc", d = "ddd";
            System.out.println("start;;;" + a);
            //设置命令行传入参数
            String[] args = new String[] { "python", "C:\\Users\\Desktop\\test1.py", a, b, c, d };
            Process pr = Runtime.getRuntime().exec(args);
            //TODO:该方法只能传递字符串
//            Process pr = Runtime.getRuntime().exec("python C:\\Users\\Desktop\\test1.py C:\\Users\\hpp\\Desktop\\test1.mp4");

            BufferedReader in = new BufferedReader(new InputStreamReader(pr.getInputStream()));
            String line;

            while ((line = in.readLine()) != null) {
//                line = decodeUnicode(line);
                System.out.println(line);
            }
            in.close();
            pr.waitFor();
            System.out.println("end");

test1.py （测试是否能取到参数）

import sys
print sys.argv[0]
print sys.argv[1]
print sys.argv[2]
print sys.argv[3]
print sys.argv[4]
