写个行情接收的小程序
思路：从sqlserver数据库读取网站，然后将实时的行情写入mysql数据库http://hq.sinajs.cn/list=sh601006，假设前面几个字段即可符合要求1、sqlserver 表
create table url(www varchar(100));
insert into url values('http://hq.sinajs.cn/list=')
create table product(code varchar(10),name nvarchar(20));
insert into product values('sh601006','大秦铁路');
insert into product values('sh601001','大同煤业');
create view v_link
as
select b.www,a.code from product as a cross join url as b
2、mysql 表
create table quotdata(
ContractId INT(11),
RisePrice decimal(20,8),
FallPrice decimal(20,8),
OpenPrice decimal(20,8),
NewPrice decimal(20,8),
3、java获取的sqlserver的网址
package andyu;
import java.sql.*;
public class connSqlServer {
public static void main(String[] srg) {
connSqlServer cServer=new connSqlServer();
}
public connSqlServer()
{
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; //加载JDBC驱动
String dbURL = "jdbc:sqlserver://localhost:1433; DatabaseName=SinaQuot"; //连接服务器和数据库test
String userName = "sa"; //默认用户名
String userPwd = "123456"; //密码
@SuppressWarnings("unused")
Connection dbConn;
try {
Class.forName(driverName);
dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
System.out.println("Connection Successful!"); //如果连接成功 控制台输出Connection Successful!
Statement s=dbConn.createStatement();
String selectsql ="select * from v_link";
ResultSet r=s.executeQuery(selectsql);
while(r.next())
{
System.out.print(r.getString("www")+r.getString("code")+"\n");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
如何写代码，因为要得较急，而我对java不是很熟，特盼高手写出，不胜感激 Java 数据库 URL --------------------编程问答-------------------- 可以了。刚开始就这样写。
这个是新浪的api --------------------编程问答-------------------- 但是我想写入mysql 数据库，而且还不会截取字符 --------------------编程问答--------------------

我暂时还只会到这里 获取字符 --------------------编程问答--------------------
你把url请求到的数据json的key转换一个实体bean的属性。根据映射建表。这样入库就是简单的bean的属性映射了 --------------------编程问答--------------------
var hq_str_sh601006="大秦铁路,7.08,7.08,7.06,7.08,7.05,7.05,7.06,2013907,14229810,795171,7.05,232900,7.04,304700,7.03,373200,7.02,90500,7.01,82594,7.06,156208,7.07,98740,7.08,35900,7.09,107400,7.10,2013-06-04,09:51:30,00";
新浪这样做就是不想别人看他行情的具体属性。哈哈

楼上显然是高手！但好像是程序片段。能具体说说怎用就好了！
补充：Java , Java SE
