网上找的教程都不完美，也许我这个教程也不完美，主要是包导入不完整，但是可以教大家如何做到完美。

1、添加jar包

commons-fileupload-1.3.1.jar
commons-io-2.2.jar
commons-lang-2.4.jar
commons-lang3-3.1.jar
commons-logging-1.1.3.jar
freemarker-2.3.19.jar
javassist-3.11.0.GA.jar
ognl-3.0.6.jar
struts2-core-2.3.16.3.jar
xwork-core-2.3.16.3.jar

2、在web.xml配置文件中配置过滤器

<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>

3、创建一个action

package com.skywo.action;public class LoginAction {// servlet api xxxpublic String execute() throws Exception{if(username != null && username.equals("skywo")){return "success";}else{return "failure";}}/*public String login() throws Exception{if(username != null && username.equals("skywo")){return "success";}else{return "failure";}}*/private String username;private String password;public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

4、配置action在struts.xml配置文件中，struts.xml放到src/下面。

<?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.enable.DynamicMethodInvocation" value="false" />    <constant name="struts.devMode" value="true" />    <package name="example" namespace="/" extends="struts-default">    <action name="login"  class="com.skywo.action.LoginAction">    <result name="success">/Success.jsp</result>    <result name="failure">/Failure.jsp</result>    </action>    </package></struts>

5、JSP调用

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><% String path= request.getContextPath();%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><title>Insert title here</title></head><body><form name="f1" action="<%=path %>/login.action" method="post"><table border="0"><tr><td>Username: </td><td><input type="text" name="username"></td></tr><tr><td>Password: </td><td><input type="password" name="password"></td></tr><tr><td colspan="2" align="center"><input type="submit" value="Login"></td></tr></table></form></body></html>

在这里要注意的是，启动tomcat的时候出现的错误不要无视，之前我就是犯了这个错误才导致了很多麻烦，一般都提示缺少包，添加对应的包即可~
