今天做作業連了一天的mysql。
最後我痛定思痛，決定從0開始學習jsp，省的又面臨不會的局面。
忙活了一晚上，終於把資料庫連接上了，不過，好傷心啊，我連個資料庫都這麼墨跡。。。
<%@ 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 伺服器的地址 String dbname="rowanhao";//MYSQL 資料庫的名字 String user="root";//MYSQL 資料庫的登入使用者名稱 String pass="zp930710";//MYSQL 資料庫的登入密碼 String port="3306";//SQL Server 服務器的連接埠號碼，預設為1433String 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>
附帶：mysql中my.ini的配置
[mysqld]# set basedir to installation path, e.g., c:/mysql # 設定為MYSQL的安裝目錄 basedir=F:/datebase/mysql# set datadir to location of data directory, # e.g., c:/mysql/data or d:/mydata/data # 設定為MYSQL的資料目錄 datadir=F:/datebase/mysql/data[WinMySQLadmin]Server=F:/datebase/mysql/mysqld-nt.exe#user=root #password=root#以上是設定WinMySQLadmin的配置 #default-storage-engine=MyISAM
