Java实现双色球历史是否中奖查询

在一些问答里，很多彩友都在问：如何查看自己的双色球号码在历史期次中有没有中过奖？作为开发者兼彩友，这个问题就简单了，决定解决一下这个问题，先上结果：双色球历史是否中奖查询网站

要实现这个功能，关键点如下：

收集双色球历史所有数据，并自动接收增量期次数据
做一个接口，传参为双色球号码，单式、复式、胆拖，然后后台接收这个号码以后，与历史每一期的数据进行对比，查看是否中奖
做一个前端展示页面，允许用户输入号码，点击查询按钮，调用2的接口，展示返回结果

采用Springboot+Freemarker引擎实现

1. 收集双色球历史所有数据

采取java jsoup爬虫方式，示例：


public class LotteryCrawler {public static void main(String[] args) {String url = "http://kaijiang.500.com/ssq.shtml"; // 双色球开奖结果页面try {crawlLotteryData(url);} catch (IOException e) {e.printStackTrace();}}public static void crawlLotteryData(String url) throws IOException {Document doc = Jsoup.connect(url).get();Elements pageLinks = doc.select("div.iSelectList a"); // 根据实际页面结构调整选择器Path csvFilePath = Paths.get("双色球开奖结果.csv");if (Files.exists(csvFilePath)) {Files.delete(csvFilePath);}List<String> csvHeader = new ArrayList<>();csvHeader.add("期号,红球1,红球2,红球3,红球4,红球5,红球6,蓝球");Files.write(csvFilePath, csvHeader, java.nio.charset.StandardCharsets.UTF_8);for (Element link : pageLinks) {String pageUrl = link.attr("href");String period = link.text();crawlLotteryPeriodData(pageUrl, period, csvFilePath);}}public static void crawlLotteryPeriodData(String url, String period, Path csvFilePath) throws IOException {Document periodDoc = Jsoup.connect(url).get();Elements balls = periodDoc.select("div.ball_box01 ul li"); // 根据实际页面结构调整选择器List<String> dataRow = new ArrayList<>();dataRow.add(period);for (Element ball : balls) {dataRow.add(ball.text());}String dataLine = String.join(",", dataRow);Files.appendString(csvFilePath, dataLine + "\n");System.out.println("第" + period + "期开奖结果录入完成");}
}

2. 查询接口

编写REST服务接口，示例：

    //查看单期是否中奖@RequestMapping(value ="/duotoneLottery/query",method = RequestMethod.GET)public List<DuotoneLotteryHistory> getDuotoneLotteriesByList(@RequestParam(value = "blue", required = false) Integer blue,@RequestParam(value = "red") String red){long startTime = System.currentTimeMillis();logger.info("begin query, blue: " + blue + ", red: " + red);List<String> ballList = Arrays.asList(red.split(","));List<Integer> balls = ballList.stream().map(Integer::valueOf).collect(Collectors.toList());Collections.sort(balls);DuotoneLotteryHistory duotoneLotteryQO = new DuotoneLotteryHistory();duotoneLotteryQO.setRed1(balls.get(0));duotoneLotteryQO.setRed2(balls.get(1));duotoneLotteryQO.setRed3(balls.get(2));duotoneLotteryQO.setRed4(balls.get(3));duotoneLotteryQO.setRed5(balls.get(4));duotoneLotteryQO.setRed6(balls.get(5));duotoneLotteryQO.setBlue(blue);QueryWrapper<DuotoneLotteryHistory> wrapper = new QueryWrapper<>(duotoneLotteryQO);List<DuotoneLotteryHistory> duotoneLotteryHistories = duotoneLotteryHistoryService.list(wrapper);logger.info("result size: " + duotoneLotteryHistories.size());String totalTime = DateUtils.getFriendlyTimeDiff(startTime, System.currentTimeMillis());logger.info("end totalTime: " + totalTime);return duotoneLotteryHistories;}

3. 前端
