jsp页面,数据库连接(

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+"/";
%>

name:

password:

处理页面 Hp.jsp 源码:
<%@ page language="java" import="java.util.*,java.sql.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>


















<%
Connection con = null;
Statement stm = null;

String url = "jdbc:mysql://localhost:3306/数据名称";//数据库名称就是你的数据库名字
String driver = "com.mysql.jdbc.Driver"; //驱动类位置
String username = "root"; //数据库登录名称,此处写上你的用户名称
String pwd = "root"; //数据库登录密码,此处写上你的登录密码
try
{
Class.forName(driver);
con = DriverManager.getConnection(url, username, pwd); //创建Connection连接对象
stm = con.createStatement(); //创建Statement 命令执行对象
}
catch (ClassNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

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();

%>


注意 连接不同数据库要导入不同的数据库驱动包 你要导入才行啊
附 sqlserver数据库连接 部分关键代码:
private static Connection con = null;
private static Statement stm = null;

private static String url = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=数据库名称";
private static String driver = "com.microsoft.jdbc.sqlserver.SQLServerDriver";//与mysql有所不同
private static String username = "sa";//默认用户
private static String pwd = "123"; //密码

static {
try {
Class.forName(driver);

con = DriverManager.getConnection(url, username, pwd);
System.out.print("连接成功!");
stm = con.createStatement();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
