今天做作业连了一天的mysql。
最后我痛定思痛，决定从0开始学习jsp，省的又面临不会的局面。
忙活了一晚上，终于把数据库连接上了，不过，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">

String server="localhost";//MYSQL 服务器的地址
String dbname="rowanhao";//MYSQL 数据库的名字
String user="root";//MYSQL 数据库的登录用户名
String pass="zp930710";//MYSQL 数据库的登录密码
String port="3306";//SQL Server 服务器的端口号，默认为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的安装目录 basedir=F:/datebase/mysql # set datadir to location of data directory, # e.g., c:/mysql/data or d:/mydata/data # 设置为MYSQL的数据目录 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
linux下部署jenkins,布布扣,bubuko.com
