一.基础实例

1.参照如下例子创建maven web工程：

2.创建一个简单的Servlet 类

package com.my.web;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/** * Servlet implementation class CallWeb */public class CallWeb extends HttpServlet {    private static final long serialVersionUID = 1L;           /**     * @see HttpServlet#HttpServlet()     */    public CallWeb() {        super();        // TODO Auto-generated constructor stub    }    /**     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)     */    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        // TODO Auto-generated method stub        response.getWriter().append("
").append("This is just a test!").append("
");        response.getWriter().append("Served at: ").append(request.getContextPath());    }    /**     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)     */    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        // TODO Auto-generated method stub        doGet(request, response);    }}

 

3.在web.xml中配置如下：

 

4.Run On Server CallWeb.class

5.在浏览器中输入如下地址即可访问：

http://localhost:8080/myWeb/CallWeb

 二.表单数据提交

1.JSP界面

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

     
      
      
个人信息:
    班级：
          
      
      
      
    用户名：
      
      
      
    密码：
      
      
      
    
          性别：
      
      女        
       
      男        
      
      保密
      
      
     
     
          
      
其他信息:
    兴趣爱好：
      足球          
      篮球          
      排球
      
      
    地址：    
                                              汝州                     郑州                                                           西安                     渭南                            
     

2.Servlet处理类

package com.my.web;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/** * Servlet implementation class Show */@WebServlet("/CallWeb")public class CallWeb extends HttpServlet {    private static final long serialVersionUID = 1L;           /**     * @see HttpServlet#HttpServlet()     */    public CallWeb() {        super();        // TODO Auto-generated constructor stub    }    /**     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)     */    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        // TODO Auto-generated method stub        request.setCharacterEncoding("UTF-8");        response.setCharacterEncoding("UTF-8");        response.setContentType("text/html");        PrintWriter pw = response.getWriter();        pw.println("班级："+request.getParameter("stuClass")+"
");        pw.println("用户名："+request.getParameter("stuName")+"
");        pw.println("密码："+request.getParameter("stuPassword")+"
");        pw.println("性别："+request.getParameter("sex")+"
");        String[] arr=request.getParameterValues("love");        for (String string : arr) {            pw.println("兴趣："+string+"
");        }        pw.println("地址："+request.getParameter("address")+"
");                }    /**     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)     */    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        // TODO Auto-generated method stub        doGet(request, response);    }}
