JAVA爬取天天基金网数据
天天基金网网址:http://quote.eastmoney.com/center/gridlist.html#fund_lof
爬取基金历史记录代码:
1。首先要自己定义几个参数:基金编码,页数,每页显示条数 开始时间结束时间等
(我这直接写的静态方法使用的 大家可以改成Test方法自行进行测试)
/** * httClient 请求 GET * 获取基金网数据1 */ public static JSONArray testDepartmentList1(String code){ Integer pageIndex = 1; Integer pageSize=20; String startTime="2018-1-1"; String endTime = "2020-4-15"; String referer = "http://fundf10.eastmoney.com/f10/jjjz_" + code + ".html"; long time = System.currentTimeMillis(); String url = "http://api.fund.eastmoney.com/f10/lsjz?callback=jQuery18306596328894644803_1571038362181&" + "fundCode=%s&pageIndex=%s&pageSize=%s&startDate=%s&endDate=%s&_=%s"; url = String.format(url,code,pageIndex,pageSize,startTime,endTime,time); System.out.println("url= " + url); System.out.println(url); HttpRequest request = HttpUtil.createGet(url); request.header("Referer", referer); String str = request.execute().body(); //获取str的长度 System.out.println("str=" + str); int length = str.length(); System.out.println("length=" + length); //indexOf返回某个指定的字符串值在字符串中首次出现的位置 int indexStart = str.indexOf("("); System.out.println(indexStart); //截取字符串 str = str.substring(indexStart + 9, length - 90); System.out.println(str); //转换为Obj类型 JSONObject jsonObject = JSON.parseObject(str); System.out.println(jsonObject); //获取数组 JSONArray jsonArray = jsonObject.getJSONArray("LSJZList"); //计算数组的长度 int size = jsonArray.size(); System.out.println(size); return jsonArray; }
通过基金编码查询基金名称
(由于查询的基金历史日期url里面的信息只有基金编号跟涨跌幅日期等 没有基金名称 我们通过基金网的查询功能自行填充基金编码进行查询)
/** * httClient 请求 GET * 获取基金网数据2 */ @Test public static String testDepartmentList2(String code) { //数据链接 String referer = "http://so.eastmoney.com/web/s?keyword="+code+""; long time = System.currentTimeMillis(); String url = "http://push2.eastmoney.com/api/qt/stock/get?ut=fa5fd1943c7b386f172d6893dbfba10b&fltt" + "=2&fields=f59,f169,f170,f161,f163,f171,f126,f168,f164,f78,f162,f43,f46,f44,f45,f60,f47," + "f48,f49,f84,f116,f55,f92,f71,f50,f167,f117,f85,f84,f58,f57,f86,f172,f108,f118,f107,f164," + "f177&invt=2&secid=0."+code+"&cb=jQuery1124006112441213993569_1587006450385&_=1587006450403"; url = String.format(url,code); System.out.println("请求url:" + url); //http请求 HttpRequest request = HttpUtil.createGet(url); request.header("Referer", referer); String str = request.execute().body(); //获取str的长度 System.out.println("str=" + str); int length = str.length(); System.out.println("length=" + length); //indexOf返回某个指定的字符串值在字符串中首次出现的位置 int i = str.indexOf("("); System.out.println(i); //截取字符串 str = str.substring(i + 55, length - 3); System.out.println(str); //转换为Obj类型 JSONObject jsonObject = JSON.parseObject(str); System.out.println(jsonObject); String fundName = jsonObject.getString("f58"); return fundName; }
业务层实现:(主要功能:用户输入基金编号查询某个基金时如果数据库没有,自动从天天基金网爬取数据存储到数据库并显示到页面上)
显示的数据分别有:基金编号 基金日期 基金名称 实际价格 每日涨跌幅
@Override public List<FundHistory> query(String fundCode) { List<FundHistory> query = fundHistoryDao.query(fundCode); if (query.size()==0) { JSONArray jsonArray = testDepartmentList1(fundCode); System.out.println(jsonArray); //计算数组的长度 int size = jsonArray.size(); System.out.println(size); //for循环遍历 for (int j = 0; j < size; j++) { JSONObject jsonObject1 = jsonArray.getJSONObject(j); //获取净值日期 String date = jsonObject1.getString("FSRQ"); //获取单位净值 Double unit = jsonObject1.getDouble("DWJZ"); //获取累积净值 Double Accumulates = jsonObject1.getDouble("LJJZ"); //获取日增长率 String growthRate = jsonObject1.getString("JZZZL"); //创建时间 DateTime dateTime = new DateTime(); //获取创建时间 String datetime = String.valueOf(dateTime); FundHistory fundHistory = new FundHistory(); fundHistory.setFundCode(fundCode); fundHistory.setDate(date); fundHistory.setUnit(unit); fundHistory.setAccumulates(Accumulates); fundHistory.setGrowthRate(growthRate); fundHistory.setCreateTime(datetime); fundHistoryDao.saveFundHistory(fundHistory); } FundHistory fundHistory = new FundHistory(); fundHistory.setFundCode(fundCode); //获取基金名称 String fundName = testDepartmentList2(fundCode); fundHistory.setFundName(fundName); fundHistoryDao.updateFundHistory(fundHistory); List<FundHistory> query2 = fundHistoryDao.query(fundCode); FundHistory fundHistory1 = query2.get(0); fundDao.saveFund2(fundHistory1); return query2; } return query; }
controller层
/** * 基金页面数据交互 * @param * @return */ @RequestMapping("/enquiryfund") @ResponseBody public Result enquiryfund(String fundCode,String fundName){ Result result = new Result<>(); if (fundCode!=""){ List<FundHistory> query = fundHistoryService.query(fundCode); if (query==null){ List<FundHistory> query2 = fundHistoryService.query(fundCode); result.setData(query2); return result; } result.setData(query); return result; }else if (fundName!=""){ List<FundHistory> fundHistories = fundHistoryService.query2(fundName); result.setData(fundHistories); return result; } return result; }
运行效果如图:
(根据基金编号进行查询基金 如果数据库没有则自动从天天基金网拉取数据并显示到页面上 共拉取20条历史数据)
