哎 我给你最简单的例子
两个简单的jsp页面,数据库连接(我给你的是mysql数据库连接示例,后面附sqlserver数据库连接部分关键代码)
首先是 获取值页面My.jsp 源码:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
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 'My.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>
<form action="Hp.jsp">
name:<input name="name" value="" type="text"></br>
password:<input name="password" value="" type="text"></br>
<input type="submit" value="button">
</form>
</body>
</html>

}
String name=request.getParameter("name"); //获取传过来的名称
String password=request.getParameter("password");//获取传过来的密码
String sql="insert into user(name,password) values("+name+","+password+")";//数据库添加一条记录sql语句
int temp=stm.executeUpdate(sql);
if(temp>0)
{
out.print("添加成功");
}
else
{
out.print("添加失败");
}
//关闭数据库连接
stm.close();
con.close();
