使用Servlet实现用户注册

1、用户注册页面代码

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

</head>

<body>

<form action="yhzhuce" method="post">

<table align="center" border="1" weight="200" height="200">

<tr align="center"><td>请填写注册信息</td></tr>
<tr><td>帐号：<input type="text" name="zh"></td></tr>
<tr><td>密码：<input type="text" name="mima"></td></tr>
<tr><td>姓名：<input type="text" name="xingming"></td></tr>

<tr><td>性别：<input type="text" name="sex"></td></tr>

<tr><td>年龄：<input type="text" name="age"></td></tr>

<tr><td>手机号码：<input type="text" name="num"></td></tr>

<tr align="center"><td><input type="submit" value="提交信息"></td></tr>

</table>

</form>

</body>

</html>

 

2、Servlet接受并验证数据

package lianxi;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class yhzhuce extends HttpServlet {
	private static final long serialVersionUID = 1L;
    
    public yhzhuce() {
        super();
        
    }
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		response.setContentType("text/html");
		response.setCharacterEncoding("UTF-8");
		String z=request.getParameter("zh");
		String m=request.getParameter("mima");
		String nm=request.getParameter("xingming");
		String s=request.getParameter("sex");
		String a=request.getParameter("age");
		String n=request.getParameter("num");
		if(nm!=""&&s!=""&&a!=""&&n!=""&&z!=""&&m!="")
		{
			response.getWriter().write("注册成功！");
			
		}
		else
		{
			response.getWriter().write("请3秒后重新填写资料！");
			response.setHeader("refresh", "3;URL=zhuceye.jsp");
		}
		//response.getWriter().append("Served at: ").append(request.getContextPath());
	}

	
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		
		doGet(request, response);
	}

}

3、运行结果

【1】输入有空时，运行结果

2、输入完整时，运行结果
