博客介绍了Java抢购程序相关内容，包含主类、工具类、Login.class、抢购线程等，还提及了pom依赖，不过表示好像没用到，此外给出了github地址，但称已被京东强制关闭。

github地址：`https://github.com/zhao458114067/Jd-Pruchase-Kill`

github已被京东强制关闭…

1、首先是`Start.class`主类：

package com.zx.jdkill.test;

import com.alibaba.fastjson.JSONObject;
import com.sun.webkit.network.CookieManager;

import java.io.IOException;
import java.net.CookieHandler;
import java.net.URISyntaxException;
import java.text.ParseException;
import java.util.concurrent.Executors;
import java.util.concurrent.PriorityBlockingQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

public class Start {
   
   
    final static String headerAgent = "User-Agent";
    final static String headerAgentArg = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.135 Safari/537.36";
    final static String Referer = "Referer";
    final static String RefererArg = "https://passport.jd.com/new/login.aspx";
    //商品id
    static String pid = "30425081079";
    //eid
    static String eid = "W2HEXZSRULGOBXAMFF6J44UTIGCP5QGKRQO5M7KZHYUAU7RT2JBTXRG2ZNRUWHKYX2PHNKRJI2KOM7BZIZ2V3F3C64";
    //fp
    static String fp = "4ce08fcab2f99f47724c9c7cdf771d9f";

    volatile static Integer ok = 2;

    static CookieManager manager = new CookieManager();


    public static void main(String[] args) throws IOException, URISyntaxException, InterruptedException, ParseException {
   
   
        CookieHandler.setDefault(manager);
        //获取venderId

        //登录
        Login.Login();

        judgePruchase();
        //开始抢购
        ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(5, 10, 1000, TimeUnit.MILLISECONDS, new PriorityBlockingQueue<Runnable>(), Executors.defaultThreadFactory(), new ThreadPoolExecutor.AbortPolicy());
        for (int i = 0; i < 5; i++) {
   
   
            threadPoolExecutor.execute(new RushToPurchase());
        }
        new RushToPurchase().run();
    }

    public static void judgePruchase() throws IOException, ParseException, InterruptedException {
   
   
        //获取开始时间
        JSONObject headers = new JSONObject();
        headers.put(Start.headerAgent, Start.headerAgentArg);
        headers.put(Start.Referer, Start.RefererArg);
        JSONObject shopDetail = JSONObject.parseObject(HttpUrlConnectionUtil.get(headers, "https://item-soa.jd.com/getWareBusiness?skuId=" + pid));
        if (shopDetail.get("yuyueInfo") != null) {
   
   
            String buyDate = JSONObject.parseObject(shopDetail.get("yuyueInfo").toString()).get("buyTime").toString();
            String startDate = buyDate.split("-202")[0] + ":00";
            Long startTime = HttpUrlConnectionUtil.dateToTime(startDate);
            //开始抢购
            while (true) {
   
   
                //获取京东时间
                JSONObject jdTime = JSONObject.parseObject(HttpUrlConnectionUtil.get(headers, "https://a.jd.com//ajax/queryServerData.html"));
                Long serverTime = Long.valueOf(jdTime.get("serverTime").toString());
                if (startTime >= serverTime) {
   
   
                    System.out.println("正在等待抢购时间");
                    Thread.sleep(300);
                } else {
   
   
                    break;
                }
            }
        }
    }
}

2、`HttpUrlConnectionUtil.class`工具类

package com.zx.jdkill.test;

import java.util.Iterator;

 */
public class HttpUrlConnectionUtil {
   
   
    /**
     * get请求
     *
     * @param headers 请求头，可为空
     * @param url
     * @return
     * @throws IOException
     */
    public static String get(JSONObject headers, String url) throws IOException {
   
   
        String response = "";
        HttpURLConnection httpURLConnection = (HttpURLConnection) (new URL(url).openConnection());
        httpURLConnection.setRequestMethod("GET");
        if (headers != null) {
   
   
            Iterator<String> iterator = headers.keySet().iterator();
            while (iterator.hasNext()) {
   
   
                String headerName = iterator.next();
                httpURLConnection.setRequestProperty(headerName, headers.get(headerName).toString());
            }
        }
        httpURLConnection.connect();
        if (httpURLConnection.getResponseCode() == 200) {
   
   
            InputStream inputStream = httpURLConnection.getInputStream(
