2、引入servrlet-api的jar文件

<dependencies>
    
    		<dependency>
    			<groupId>org.apache.tomcat</groupId>
    			<artifactId>servlet-api</artifactId>
    			<version>6.0.33</version>
    			<type>jar</type>
    			<scope>provided</scope>
    		</dependency>
    	</dependencies>

3、引入自动复制war文件到tomcat的目录下的插件

<build>
    		<finalName>user-web</finalName>
    
    		<plugins>
    			<plugin>
    				<groupId>com.github.goldin</groupId>
    				<artifactId>copy-maven-plugin</artifactId>
    				<version>0.2.5</version>
    				<executions>
    					<execution>
    						<id>copy-war</id>
    						<phase>package</phase>
    						<goals>
    							<goal>copy</goal>
    						</goals>
    						<configuration>
    							<resources>
    								<resource>
    									<targetPath>${catalina.home}/webapps</targetPath>
    									<directory>${project.build.directory}</directory>
    									<includes>
    										<include>user-web.war</include>
    									</includes>
    								</resource>
    							</resources>
    						</configuration>
    					</execution>
    				</executions>
    			</plugin>
    		</plugins>
    	</build>

4、编写测试的Servlet

public class HelloServlet extends HttpServlet {
    
    	/**
    	 * 
    	 */
    	private static final long serialVersionUID = 1L;
    
    	@Override
    	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    
    		req.setAttribute("username", "zhang");
    		req.getRequestDispatcher("/hello.jsp").forward(req, resp);
    	}
    
    	@Override
    	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    		doGet(req, resp);
    	}
    
    }

5、web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    	id="WebApp_ID" version="2.5">
    	<display-name>Archetype Created Web Application</display-name>
    	<servlet>
    		<servlet-name>HelloServlet</servlet-name>
    		<servlet-class>cn.ztedu.servlet.HelloServlet</servlet-class>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>HelloServlet</servlet-name>
    		<url-pattern>/hello.do</url-pattern>
    	</servlet-mapping>
    </web-app>

6、hello.jsp测试页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    	pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    	<h1>Hello---->${username}</h1>
    </body>
    </html>

7、启动tomcat，访问web项目
