            //数据库用户名
            String userName = "root";
            //数据库密码
            String password = "root";
            //加载驱动程序
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            //创建conn对象连接数据库
            Connection conn = DriverManager.getConnection(url,userName,password);
            //创建stmt对象提交SQL语句到数据库
            Statement stmt = conn.createStatement();
            //mysl语句
            String sql = "select * from data";
            //执行查询
            ResultSet rs = stmt.executeQuery(sql);
            int i = 0;
            while (rs.next()){
                i++;
                out.println("
