Java WEB之Servlet学习之路（一）一个最简单的Servlet应用

   好久没有更新博客了，有点冷清，主要是最近忙着看Java WEb前段时间都是基础，一些http理论和WEB容器理论，没有什么实践性代码，所以没写代码，现在终于正式开始Servlet编程了，下面就得好好的开始写代码了呃，下面奉上第一篇，Setblet的Hello World!!!

首先放上Setvlett代码

package com.bird.servlet; 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 ServletDemo2 extends HttpServlet { private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.getOutputStream().write("Bird".getBytes()); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } }

下面是相对应的Web.xml的配置文件的代码

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <servlet> <servlet-name>ServletDemo</servlet-name> <servlet-class>com.bird.servlet.ServletDemo</servlet-class> </servlet> <servlet> <servlet-name>ServletDemo2</servlet-name> <servlet-class>com.bird.servlet.ServletDemo2</servlet-class> </servlet> <servlet-mapping> <servlet-name>ServletDemo</servlet-name> <url-pattern>/ServletDemo</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>ServletDemo2</servlet-name> <url-pattern>/servlet/ServletDemo2</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
这样的话，在Eclipse中就可以装载一个Tomcat运行了，呵呵，简单吧，，。，，，，淡定
