在Java通过python命令执行DataX任务

package test;

import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;

public class TestDatax {
     public static void main(String[] args) {
            try {
                System.out.println("start");
                
                String windowcmd = "cmd /c python2 datax.py F:\\json.json";
               
                //.exec("你的命令",null,new File("datax安装路径"));
                Process pr = Runtime.getRuntime().exec(windowcmd,null,new File("D:\\DataX\\datax\\bin"));
                BufferedReader in = new BufferedReader(new InputStreamReader(pr.getInputStream()));
                String line = null;
                while ((line = in.readLine()) != null) {
                    System.out.println(line);
                }
                in.close();
                pr.waitFor();
                System.out.println("end");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

    }
