1、命令行执行以下语句

mvn archetype:create -DgroupId=com.watson -DartifactId=s2sh -DarchetypeArtifactId=maven- archetype-webapp

就会在当前目录下创建一个myWebapp的web工程

2、我们使用struts2框架,需要添加struts2的依赖到pom.xml里面。

3、我们使用jetty容器来运行我们的web项目,添加jetty的插件到pom.xml里面。

pom.xml

<span style="font-family:Microsoft YaHei;"><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.watson</groupId>  <artifactId>s2sh</artifactId>  <packaging>war</packaging>  <version>1.0-SNAPSHOT</version>  <name>s2sh Maven Webapp</name>  <url>http://maven.apache.org</url>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency><dependency>  <groupId>org.apache.struts</groupId>  <artifactId>struts2-core</artifactId>  <version>2.2.1</version></dependency><dependency>  <groupId>log4j</groupId>  <artifactId>log4j</artifactId>  <version>1.2.14</version></dependency><dependency>  <groupId>javassist</groupId>  <artifactId>javassist</artifactId>  <version>3.8.0.GA</version></dependency>  </dependencies>  <build>    <finalName>s2sh</finalName><defaultGoal>install</defaultGoal>  <plugins>   <plugin><groupId>org.mortbay.jetty</groupId><version>6.1.22</version><artifactId>maven-jetty-plugin</artifactId><configuration> <contextPath>/</contextPath> <scanIntervalSeconds>3</scanIntervalSeconds> <connectors>  <connector implementation="org.mortbay.jetty.nio.SelectChannelConnector">   <port>7002</port>   <maxIdleTime>60000</maxIdleTime>  </connector> </connectors></configuration>   </plugin>  </plugins>  </build></project></span>

4、然后进入工程目录下执行mvn compile,编译成功则表示配置正确。

5、在s2sh\src\main下面添加java文件夹存放java文件,添加resources文件夹存放配置文件,webapp是 web相关的文件。
在webapp文件夹下打开web.xml添加struts2的过滤器。

<span style="font-family:Microsoft YaHei;"><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app>  <display-name>s2 Web Application</display-name>    <filter>        <filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern></filter-mapping></web-app></span>

6、在java目录下新建一个类HelloWorldAction

<span style="font-family:Microsoft YaHei;">package com.watson.s2sh.action;import com.opensymphony.xwork2.ActionSupport;public class HelloWorldAction extends ActionSupport {private static final long serialVersionUID = 1L;public String execute() throws Exception {System.out.println("hero world");return SUCCESS;}}</span>

7、在webapp的目录下添加一个jsp文件,HelloWorld.jsp,内容如下

<span style="font-family:Microsoft YaHei;"><%@ page language="java" contentType="text/html; charset=ISO-8859-1"        pageEncoding="ISO-8859-1"%><%@ taglib prefix="s" uri="/struts-tags"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loo<html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Hello World!</title></head><body>        <h2>                <s:property value="messageStore.message" />        </h2></body></html></span>

8),在resources目录下添加struts.xml文件,内容如下:

<span style="font-family:Microsoft YaHei;"><?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts><constant name="struts.devMode" value="true" />        <package name="basicstruts2" extends="struts-default"><action name="index"><result>/index.jsp</result></action><action name="hello" class="com.watson.s2sh.action.HelloWorldAction" method="execute"><result name="success">/HelloWorld.jsp</result></action> </package></struts></span>

9、在工程目录下面/s2sh,使用mvn jetty:run来运行web应用。

10、启动完成后,访问如下链接:

http://localhost:7002/s2sh/hello:访问HelloWorldAction,跳转到HelloWorld.jsp.

http://localhost:7002/s2sh/index:访问index.jsp页面。
