jsp表单数据添加到数据库

先由表单提交数据到某验证页面：checkregister.jsp
<form method="POST"name="form1" action="checkregister.jsp" onsubmit="return check()">

在checkregister.jsp这里可以直接传给数据库，我加了一个页面输出，为了直观的观察数据：

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%@page import="java.sql.*" %>
<%@page import="java.sql.DriverManager"%>
<%@page import="java.sql.Connection"%>
<%@page import="java.sql.PreparedStatement" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>登记验证</title>
</head>
<body>

<%

/*浏览器提交的数据在提交给服务器之前设置编码方式为UTF-8*/
	request.setCharacterEncoding("UTF-8");
	out.println("用户名："+request.getParameter("User")+"<br>");
	out.println("密码："+request.getParameter("pwd")+"<br>");
	out.println("性别："+request.getParameter("sexy")+"<br>");	
	out.println("密保问题："+request.getParameter("secret")+"<br>");	
	out.println("密保问题答案："+request.getParameter("pwd2")+"<br>");
%>

 <%

        request.setCharacterEncoding("UTF-8");
    	String dbURL="jdbc:sqlserver://localhost:1433;DatabaseName=Users";//此处为你的库名
    	//Connection conn=null;
    	//String driverName="com.microsoft.sqlserver.jdbc.SQLServerDriver";
    	Connection conn=null;
    	String userName="sa";
    	String pwd="xxxx";//xxxx是你的数据库登录密码
    	Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    	conn = DriverManager.getConnection(dbURL,userName,pwd);
    	
    	String sql="insert into Users2(username,password,question,answer,gender)values(?,?,?,?,?)";//此处username等是指数据库里的属性名
    	PreparedStatement stmp=conn.prepareStatement(sql);
    
	
	String username=request.getParameter("User");
	String password=request.getParameter("pwd");
	String question=request.getParameter("secret");
	String answer=request.getParameter("pwd2");
	//int gender=Integer.parseInt(request.getParameter("sexy"));
	String gender=request.getParameter("sexy");
   // int sage=Integer.parseInt(request.getParameter("Sage"));
            stmp.setString(1,username);
            stmp.setString(2,password);
            stmp.setString(3,question);
            stmp.setString(4,answer);
            stmp.setString(5,gender);

            int n=stmp.executeUpdate();
            if(n==1){%>数据插入成功！<br><%}  
            else{%>数据插入失败！<br><%}
%>        
     
   
</body>
</html>

　记得加入executeUpdate
