开始过滤器的异常struts2 java.lang.ClassNotFoundException：org.apache.struts2.dispatcher.FilterDispatcher

Question

我一直在使用ORM进行ORM，使用eclipse作为我的IDE。我使用Maven作为我的构建系统。在学习Struts之后，我试图让一个Hello World世界运转起来。但是，我不知道是什么问题，它不断给我：

SEVERE: Exception starting filter struts2 
java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.FilterDispatcher 

这里是文件夹结构是什么样的：

的pom.xml：引擎收录here

web.xml中：

<?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>wah</display-name> 

    <filter> 
     <filter-name>struts2</filter-name> 
     <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> 
    </filter> 

    <filter-mapping> 
     <filter-name>struts2</filter-name> 
     <url-pattern>/*</url-pattern> 
    </filter-mapping> 

    <welcome-file-list> 
     <welcome-file>index.html</welcome-file> 
    </welcome-file-list> 

</web-app> 

struts.xml中：

<?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="default" namespace="/" extends="struts-default"> 
     <action name="Menu"> 
      <result>/menu.jsp</result> 
     </action> 
    </package> 

</struts> 

引入了menu.jsp有一个简单的Hello World文本。

有人可以帮我解释为什么我会得到ClassNotFoundException错误。我该如何解决它？什么是建议的目录结构设置一个struts 2项目？

这是我的应用程序文件夹结构，做工精细看到

，这是pom.xml的

，这是web.xml文件
