以大秦鐵路(股票代碼:601006)為例,如果要獲取它的最新行情,只需訪問新浪的股票數據接口:/list=sh601006這個url會返回壹串文本,例如:
var hq_str_sh601006="大秦鐵路, 27.55, 27.25, 26.91, 27.55, 26.20, 26.91, 26.92,
22114263, 589824680, 4695, 26.91, 57590, 26.90, 14700, 26.89, 14300,
26.88, 15100, 26.87, 3100, 26.92, 8900, 26.93, 14230, 26.94, 25150, 26.95, 15220, 26.96, 2008-01-11, 15:05:32";
這個字符串由許多數據拼接在壹起,不同含義的數據用逗號隔開了,按照程序員的思路,順序號從0開始。
0:”大秦鐵路”,股票名字;
1:”27.55″,今日開盤價;
2:”27.25″,昨日收盤價;
3:”26.91″,當前價格;
4:”27.55″,今日最高價;
5:”26.20″,今日最低價;
6:”26.91″,競買價,即“買壹”報價;
7:”26.92″,競賣價,即“賣壹”報價;
8:”22114263″,成交的股票數,由於股票交易以壹百股為基本單位,所以在使用時,通常把該值除以壹百;
9:”589824680″,成交金額,單位為“元”,為了壹目了然,通常以“萬元”為成交金額的單位,所以通常把該值除以壹萬;
10:”4695″,“買壹”申請4695股,即47手;
11:”26.91″,“買壹”報價;
12:”57590″,“買二”
13:”26.90″,“買二”
14:”14700″,“買三”

19:”26.87″,“買五”
20:”3100″,“賣壹”申報3100股,即31手;
21:”26.92″,“賣壹”報價
(22, 23), (24, 25), (26,27), (28, 29)分別為“賣二”至“賣四的情況”
30:”2008-01-11″,日期;
31:”15:05:32″,時間;
相應地,也可以獲得深市相關股票信息,但是這種方法的弊病是只能獲得最新的或者是當天的股票數據,無法將歷史數據導入到數據庫,當然,妳也可以以某壹天為起始點自己重新創造歷史數據。所以繼續尋找其他網站接口,終於找到了雅虎財經網站,它提供的接口可以直接把股票歷史數據導成Excel,真實太方便了!直接在瀏覽器地址中數據網址即可/table.csv?s=股票代碼,但是如果手動輸入再逐壹下載保存簡直是太麻煩了,光上證股票就800多個,估計剛手動下載完就又開盤了還得重新下載。所以我的思路是,1、利用多線程方法下載股票文件。2、將這些文件統壹導入數據庫。
1.1文件下載類:
import java.io.*;
import java.net.*;
import java.util.List;
import fatowen.stocksystem.sysconfig.data.DownLoadVO;
public class HttpDownFile {
private static int BUFFER_SIZE = 8096;
/**根據URL下載文件並保存
* @param destUrl String
* @param fileName String
* @throws Exception
*/
public void saveToFile(String destUrl, String fileName) throws IOException {
FileOutputStream fos = null;
BufferedInputStream bis = null;
HttpURLConnection /table.csv?s=";
String result = "";
String savePath = "";
public HisDataAddThread(List paramList,String savePath){
this.myParamList = paramList;
this.savePath = savePath;
}
public void run() {
while(runFlag){
downLoadData = PublicDataUtil.getDownLoadData(myParamList);
if(!Lib.isEmpty(downLoadData)){
HttpDownFile oInstance = new HttpDownFile();
try {
oInstance.saveToFile(baseUrl + downLoadData, savePath + downLoadData + ".csv");
}catch (Exception err) {
System.out.println(err.toString());
}
}else{
runFlag = false;
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public List getFailureList() {
return failureList;
}
public void setFailureList(List failureList) {
this.failureList = failureList;
}
public List getSuccessList() {
return successList;
}
public void setSuccessList(List successList) {
this.successList = successList;
}
}
2.將下載完的文件統壹保存到數據庫工具類

else
return null;
}
//取得指定列的值

return null;
}
StringBuffer scol = new StringBuffer();

}
}
String str=new String(scol.toString());
str = str.substring(0, str.length() - 1);
return str;
}
//取得指定行,指定列的值
public String getString(int row, int col) {
String temp = null;
int colnum = this.getColNum();
if(colnum > 1){
temp = list.get(row).toString().split(",")[col];
}else if(colnum == 1) {
