用jsp+Servlet实现简单的提交表单并显示的注册

目录结构：

步骤：

1、注册表单页面register.jsp

2、处理注册表单信息并实现显示的Servlet：HomeWork.java

3、显示信息的页面：output.jsp

4、修改web.xml，配置servlet信息

register.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

  
    
  
  
  

 
注册页面填写
  


  姓名


  性别男
女


出生年月 


  民族


个人介绍 


    

 

  

output.jsp：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

  
    
  
  
  <% request.setCharacterEncoding("UTF-8");%> //防止乱码
  
用户注册信息如下：
 <%=request.getAttribute("outputMessage") %>
   

HomeWork.java：

package servlets;

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

public class HomeWork extends HttpServlet {
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
	}
	
	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		response.setContentType("text/html;charset=utf-8 ");
		request.setCharacterEncoding("UTF-8");
		PrintWriter out = response.getWriter();
		String yourname=request.getParameter("yourname");
	    String sex=request.getParameter("sex");
	    String userdate=request.getParameter("userdate");
	    String minzu=request.getParameter("minzu");
	    String introduction=request.getParameter("introduction");
		out.println("您的姓名是："+yourname+"
");
		out.println("您的性别是："+sex+"
");
		out.println("您的出生日期是："+userdate+"
");
		out.println("您的民族是："+minzu+"
");
		out.println("您的个人介绍是："+introduction+"
");
		out.flush();
		out.close();
		 request.setAttribute("outputMessage", out);
		    request.getRequestDispatcher("/output.jsp").forward(request,response);
	}
}

修改web.xml：

  
    This is the description of my J2EE component
    This is the display name of my J2EE component
    HomeWork  //修改成你的servlet名
    servlets.HomeWork //要修改的地方
  
  
    HomeWork //要修改的地方
    /HomeWork //要修改的地方
