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
