jsp连接mysql----------第一篇技术类文章

今天做作业连了一天的mysql。

最后我痛定思痛，决定从0開始学习jsp。省的又面临不会的局面。

忙活了一晚上。最终把数据库连接上了，只是。好伤心啊，我连个数据库都这么墨迹。

。

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<%@page import="data.database"%>

<%@page import="java.sql.*"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    <title>My JSP 'index.jsp' starting page</title>

	<meta http-equiv="pragma" content="no-cache">

	<meta http-equiv="cache-control" content="no-cache">

	<meta http-equiv="expires" content="0">

	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

	<meta http-equiv="description" content="This is my page">

	<!--

	<link rel="stylesheet" type="text/css" href="styles.css">

	-->

  </head>

  <body>

    This is my JSP page. <br>

    <%

    String server="localhost";//MYSQL 服务器的地址    

    String dbname="rowanhao";//MYSQL 数据库的名字    

    String user="root";//MYSQL 数据库的登录username    

    String pass="xxxxx";//MYSQL 数据库的登陆password    

    String port="3306";//SQL Server 服务器的端口号。默觉得1433

	String url ="jdbc:mysql://"+server+":"+port+"/"+dbname+"?user="+user+"&password="+pass+"&useUnicode=true&characterEncoding=GB2312";

	Class.forName("org.gjt.mm.mysql.Driver").newInstance();

	Connection conn= DriverManager.getConnection(url);

	Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);

    String sql="select * from student";

    ResultSet rs=stmt.executeQuery(sql);

    while(rs.next())

    {

    	out.println(rs.getString(1));

    }

    rs.close();

    out.println("aaa");

     %>

  </body>

</html>

附带：mysql中my.ini的配置

[mysqld]

# set basedir to installation path, e.g., c:/mysql

# 设置为MYSQL的安装文件夹

basedir=F:/datebase/mysql

# set datadir to location of data directory,

# e.g., c:/mysql/data or d:/mydata/data

# 设置为MYSQL的数据文件夹

datadir=F:/datebase/mysql/data

[WinMySQLadmin]

Server=F:/datebase/mysql/mysqld-nt.exe

#user=root

#password=root

#以上是设置WinMySQLadmin的配置

#default-storage-engine=MyISAM
