A. 股市行情數據導入資料庫
你下載excel 再手工轉成 SQL類型的數據,只手工進行,或者是做2個程序,一個程序是固定時間段自動下載某個網站的數據excel 表,再作個程序,固定時間段將excel 自動轉成SQL,也可以2程序做一起,不過這種方法只能算手工自動話,談不上動態數據更新(因為數據更新反映時間過長),而且程序製作和運行的工作量巨大.
要想完全的數據動態更新,你必須和對方的資料庫有數據連接.基本上要花錢,估計也是你最難辦到的,你看那些股票類網站那個不要花錢花去採集數據源?
B. 如何獲取股票數據與歷史數據以資料庫方式存儲的
股票歷史數據查詢有個很不錯的網頁工具可以推薦,地址是http://tool.cnfunny.cn/#/打開就可以直接使用,還可以大批量下載,方便省事!
C. 如何實時寫股票數據進資料庫
既然你自己設計了一個資料庫,現在是每天收盤後,從同花順軟體里導出EXCEL,再導入資料庫,來進行分析。那麼你想及時查看開盤數據,那就用同樣的技術,從同花順軟體里導出EXCEL,再導入資料庫進行分析好了,向你學習!
D. 如何把股票數據導入資料庫
先從菜單欄里找到數據導出(保存),導出為EXCEL,然後打開統計軟體或資料庫,再找到文件(數據)導入,把EXCEL導入。
一般都是這個方法,不同的軟體有一定差異。
E. java爬蟲實時獲取頁面數據並存入資料庫
response push的html標簽你能拿到,就能按規律全部遍歷出來,代碼網上很多
F. 如何把股票的即時行情的數據添加到資料庫里
股票行情是什麼格式的數據?
G. 怎麼做實時的股票資料庫
如果主站提供有相關的介面的話,可以調主站的介面.如果主站不提供相關介面.那就不不斷抓取.獲取最新的信息了.
H. 如何批量獲取股票實時數據,並存儲在本地
1. 股票交易數據量實在太大,Excel不能勝任。
2. 股票交易的數據介面似乎也不太好找
I. Java 從網頁抽取數據 存入資料庫
台風的編號和名稱直接在源碼中有,但時間和地理位置我只能跟蹤到
function totf(tfbh){
location.href( "Typhoon.aspx?id="+tfbh);
}
數據需要從aspx中拿到的,應該是存放到資料庫的,頁面上是拿不到的
我認為可以通過循環模擬發送請求Typhoon.aspx?id="+XXX,然後通過解析response包的方式可以獲得詳細的信息
下面一個頁面是講模擬發送請求的

希望對你有幫助
我寫了一段獲得一組數據的代碼
//get Typhoon content by param
public static String getTyphoon(String param) {
URL url = null;
try {
url = new URL(param);
} catch (MalformedURLException e) {
e.printStackTrace();
}
HttpURLConnection connection = null;
InputStream is = null;
try {
connection = (HttpURLConnection) url.openConnection();
is = connection.getInputStream();
} catch (IOException e) {
e.printStackTrace();
}
BufferedInputStream bis = new BufferedInputStream(is);
int len = 0;
byte[] buf_all = new byte[0];
try {
while (true) {
byte[] buf1 = new byte[4096];
byte[] buf2 = buf_all;
len = bis.read(buf1);
if(len <= 0){
break;
}
buf_all = new byte[len+buf2.length];
System.array(buf2, 0, buf_all, 0, buf2.length);
System.array(buf1, 0, buf_all, buf2.length, len);
}
} catch (IOException e) {
e.printStackTrace();
}
String content = null;
try {
content = new String(buf_all, "utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
int startIndex = content.indexOf("var ary0=")+9;
content = content.substring(startIndex);
int endIndex = content.indexOf("var aryyb0=");
content = content.substring(0, endIndex);
return content;
}
得到的結果是這樣的:

再下去字元串的拆分實在是太復雜了,不想寫了
使用時只要參數為http://www.wztf121.com/Typhoon.aspx?id=
id後是台風的代碼號,寫一個循環就可以了
