以GenericServlet创建Servlet

1、在FirstServlet同文件夹下建立GServlet.java

package com.hunhun;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class GServlet extends GenericServlet{
	
   public void service(ServletRequest req,
             ServletResponse res)
             throws ServletException,
                    IOException{

            res.getWriter().println("GenericServlet "+new Date().toLocaleString());

      
    }
}

<?xml version="1.0" encoding="ISO-8859-1"?

> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0" metadata-complete="true"> <servlet> <servlet-name>FirstServlet</servlet-name> <servlet-class>com.hunhun.FirstServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>FirstServlet</servlet-name> <url-pattern>/FirstServlet</url-pattern> </servlet-mapping> <servlet> <servlet-name>GServlet</servlet-name> <servlet-class>com.hunhun.GServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>GServlet</servlet-name> <url-pattern>/GServlet</url-pattern> </servlet-mapping> </web-app>

3、编译文件，reload myweb项目，注意每次又一次改动*Servlet.java文件,都须要又一次编译，并又一次载入 myweb项目或重新启动tomcat7

4、浏览器訪问 http://localhost:8080/myweb/GServlet，可看到
