jsp留言板 对刚学的希望有帮助,程序很简单的

package db;

import java.sql.*;

public class DBConnection
{
    // 提供用户名和密码
    private static String user="sa";
    private static String password="123";

    public static Connection getConnection() {
        Connection con;
        try {
           // 加载驱动程序
           Class.forName(Config.DBdriver);
           // 创建连接
           con = DriverManager.getConnection(Config.DBurl, user, password);
           return con;
        } catch (ClassNotFoundException e) {
            System.out.println( e.getMessage() );
        } catch (SQLException e) {
            System.out.println( e.getMessage() );
        }
        return null;
    }
}
