1. 创建一个继承于GenericServlet的类

bubuko.com,布布扣

3. 重写Server方法

package cn.school;

import java.io.IOException;

import javax.servlet.GenericServlet;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class ServletDemo extends GenericServlet {

        @Override
        public void service(ServletRequest req, ServletResponse res)
                throws ServletException, IOException {        
            res.getOutputStream().write("Hello world wokaoa".getBytes());        
        }
}

4. 导入tomcat源码

5. 要在MyEclipse中集成tomcat

window-》Preference-》MyEclipse-》Servers-》Tomcat-》我这里选择的是7.x

然后导入tomcat路径

bubuko.com,布布扣

6. 把web项目加入到tomcat服务器里面去

bubuko.com,布布扣

7. 配置外部访问路径

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    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_2_5.xsd">
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <servlet>
    <servlet-name>ServletDemo</servlet-name>
    <servlet-class>cn.school.ServletDemo</servlet-class>
  </servlet>
  
  <servlet-mapping>
     <servlet-name>ServletDemo</servlet-name>
     <url-pattern>/ServletDemo</url-pattern>
  </servlet-mapping>

</web-app>
