1、导入Jar包

2、配置web.xml

  1 <?xml version="1.0" encoding="UTF-8"?>
  2 <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
  3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
  5     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  6     <welcome-file-list>
  7         <welcome-file>login.jsp</welcome-file>
  8     </welcome-file-list>
  9
 10     <filter>
 11         <filter-name>struts2</filter-name>
 12         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
 13     </filter>
 14
 15     <filter-mapping>
 16         <filter-name>struts2</filter-name>

     "http://struts.apache.org/dtds/struts-2.3.dtd">

 <struts>
      <!-- 启动开发者模式，便于调试 -->
      <constant name="struts.devMode" value="true"/>
     <package name="hello"  namespace="/hello"  extends="struts-default">
         <action name="main" class="com.aaron.action.HelloAction">
             <result>/WEB-INF/jsp/main.jsp</result>
