java数据库编程

首先添加jdbc驱动，去官网上下，然后添加如下代码
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.*;
public class Dbconn {
public Connection getConnection()
{
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String dbURL = "jdbc:sqlserver://localhost:1433;DataBaseName=LD";
String userName = "admin";
String userPwd ="123";

Connection dbConn = null;
try {
Class.forName(driverName);//加载jdbc
dbConn = DriverManager.getConnection(dbURL, userName, userPwd);//建立连接
System.out.println("Connection Successful!");
}
catch (Exception e) {
// e.printStackTrace();
System.out.println(e.getMessage());
}
return dbConn;
}

}

呵呵，我就多说一点吧，反正无聊~(@^_^@)~
其实与数据库交互
